Pump Pressure Computer
Fire Research Corporation has added a pump pressure computer to its fire fighting line. The manufacturer states that the instrument will compute the required output pressure on any type of standard hose lay and nozzle operation currently in use by the fire service.
Designed to be flush-mounted on a pumper panel, it operates off 12 volts DC and is lighted for nighttime operation. To use, one simply dials the size of the hose, the number of lengths of hose and the type of nozzle used. The right-hand gage is adjusted for the desired nozzle pressure and the left-hand gage then automatically indicates the pressure required at the pump.

Coolant Aeration Detector
The Water-Larm manufactured by Larmco, a subsidiary of Standard Controls, Inc., warns the operator of a diesel or gasoline engine when the cooling system begins pumping air, before temperature gages can react to a potential overheating condition and before damage can occur. By filtering and sampling the coolant, it detects air bubbles caused by internal and external leakage or low coolant level and activates a red aircraft light on the dash panel.
The unit is available as a factory-installed option from all major diesel engine equipment manufacturers, or as a kit for installation in the buyer’s own shop or maintenance facility.
To guard against possible malfunction, a push-to-test switch is wired into the system.

First Aid Kits
Scott Aviation now manufactures and markets a complete line of first aid kits and refills. These kits were formerly produced by Davis Emergency Equipment Company. Earlier this year Davis, a Division of “Automatic” Sprinkler Corporation of America, was combined with the Scott division of the same parent corporation. Their products now bear the name, Scott Aviation, Davis Products.
By employing the interchangeable unit system—D Carton type, a customer may purchase the assortment best suited to his own specific requirements. Size of kits varies from small pocket size to full 36-unit cabinets.
All units are wrapped in cellophane with quick-opening pull tab. When the tab is not in evidence, it indicates that the package has been opened. Transparent windows show contents at a glance.

Revolving Emergency Light
K-D Company is introducing the No. 888 Wobble light, which has chromeplated solid brass base and incorporates a heavy-duty motor, plus a ball-bearing race for the revolving assembly.
The light pattern is achieved by the use of two tilted, clear, sealedbeam units and two red units. Designed for toggle mounting, the light stands 10 inches high and measures 10 1/8 inches across the base. It is supplied with a moistureproof neoprene mounting pad.
Other models of the series include a choice of two, three or four sealed beam units and either red, amber or blue lens.

Dana Corporation’s Clutch & Marine Division announces the Spicer Angle-Spring clutch.
The patented device provides such features as constant plate load, reduced pedal effort and shorter pedal stroke. Pedal effort is reduced up to 35 percent, eliminating the need for a pedal assisting device and making it possible to shorten the in-cab clutch pedal stroke.
Constant plate load is possible because the clutch compensates for normal loss of spring load during driven disk wear by automatically changing spring positions. This is said to provide like-new torque capacity throughout the wear life of the clutch facing material.
Direct interchangeability with the 14-inch. 2-plate, pull-type clutch is possible with the new clutch.

Hose Cabinet Shield
A cardboard shield has been developed by Potter-Roemer, Inc., to protect the company’s fire hose and fire extinguisher cabinets from plaster, paint and other contamination during construction of commercial and industrial structures.
The cover, which now is included free with each unit manufactured by Potter-Roemer, was developed because of the destructive effect of certain building materials during construction.
Various cover sizes are available for different cabinet models. When the cabinet is set in the wall, the cover is easily applied with masking tape by the contractor until construction is completed.

A portable inhalator that can supply oxygen within seconds to heart attack victims and other emergency cases is being marketed by Mine Safety Appliances Company.
To administer the oxygen, the user places the Oxygen Administrator’s plastic mask on the patient’s face and turns a handwheel which opens an oxygen cylinder valve, permitting oxygen to flow continuously at a rate of approximately 6 liters per minute. The unit provides a 1-hour oxygen supply which enables transport of the victim, if necessary.
Equipped with an elastic headband, the face mask has a rebreathing bag which acts as a volume reservoir and permits deep inhalation. A circular pattern of tiny holes on the side of the mask enables atmospheric air to mix with the oxygen and assures adequate flow for inhalation. An easyto-read pressure gage serves as a constant check on the supply of oxygen available. A pressure regulator assures the present rate of flow regardless of cylinder pressure.
Housed in a compact, sturdy carrying case, the entire unit is 22 1/2 inches long by 6 inches wide by 9 inches high, and weighs only 13 1/2 pounds.

Audio-Visual Warning System
A speaker-light for vehicle roof mounting has been developed by Sireno Signal Mfg. Corp. A twin sealed-beam, 360° revolving light and an electronic siren-speaker are self-contained in a single unit.
Weighing only 14 pounds, the unit measures only 12 inches at the base and 11 1/2 inches high. Two units can be mounted on a single bar without roof reinforcement, providing two separate revolving lights and speakers for use with a 125-watt Sireno electronic siren.
The dome can be removed for easy relamping. Red, amber, blue, clear or split-color domes are available. Any combination of red, amber, blue or white bulbs can be supplied with clear domes.
The speaker-light is rated at 75 watts for use with Sireno Models SFD3, SFD4, SFD5 and SFD6 electronic sirens.

A fire-retardant paint that is said to provide protection against structural failure of wood, wallboard, plaster, acoustical tile and the warpage of steel during high-intensity industrial fires has been developed by Cheesman-Elliot, a division of the Seagrave Corporation.
Known as Firehold 10, the paint, which can be applied by brush, roller or spray, begins to puff into a foamlike insulating mat when exposed to a temperature of 350°F. This foam expands to over 200 times its original thickness the manufacturer declares. Firehold 10 has been listed 10 by Underwriters’ Laboratories, Inc., following experiments in which two coats of the paint were applied to wood and exposed to the UL tunnel test.

A safety tilt can mounted on a sturdy frame for safe transfer of flammable liquids into small containers has been developed by Justrite Manufacturing Company.
The can features a self-closing faucet, which eliminates loss through dripping, and a capped fill opening with a built-in vent for automatic pressure and vacuum relief during storage or draining. Both faucet and fill opening are equipped with flash arrestor screens to keep sparks or flames from entering. Flow of liquid from the 5-gallon can is controlled by the amount of pressure on the faucet and the angle of the can itself. When dispensing of flammables is completed, the faucet closes automatically and the can returns to the upright position.

Scott Aviation, a division of A-T-O Inc., announces a self-contained, oxygen inhalator-resuscitator.
It is used as an inhalator for the breathing patient and a resuscitator for the nonbreathing patient. When resuscitation is required, a resuscitator mask is snapped onto the control head, the oxygen is turned on, and the unit is ready for instant use. When unassisted breathing begins, the operator removes the resuscitator mask from the patient’s face and replaces it with the demand inhalator mask, with mask-mounted regulator. Both the inhalator and the resuscitator may be used simultaneously on two persons if required.
All components fit into a compact, high-impact oxygen-identifying green plastic case. The complete unit weighs only 19 pounds and includes a Scott Duo-Seal facepiece with a mask-mounted demand regulator for use as an inhalator mask, a resuscitator control head with both an adult and a child’s mask, a “D” size oxygen cylinder and valve assembly, a pressure-reducing regulator, a gage and outlet assembly, and a cascading hose assembly. The unit offers between 20 and 30 minutes duration.
