A compact, completely housed electric power plant designed for such mobile applications as emergency lights, saws, rescue equipment, etc., has been developed by the Onan Division of Onan Corporation.
Called the Power Drawer, the self-contained power package is adaptable to both new and existing vehicles. No separate compartment or mounting plate is required and only four bolts are needed to secure the outfit.
Slide rail frame design and flexible connections enable the generator to be unlatched and extended 24 inches from flush against the vehicle.
The electric plant is available in 4000 and 6000 watts. Both models are powered by Onan Vacu-flo gasoline, air-cooled, twocylinder, opposed, 4-cycle engines.

Emergency Vehicle Signals
The Su-Power system of emergency vehicle signals developed by Unity Manufacturing Company uses a Par 46 rotating beacon and high-candlepower Hi-dome warning lights along with the Si-tron siren/PA system.
The Par 46 Unibeacons, available with the Spitfire dome, employs four 60,000candlepower, 6-inch sealed-beam lamps. They produce approximately 115 flashes per minute with up to 100 percent longer dwell per flash.
The Hi-dome warning lights feature a Par-36, 5-inch lamp which provides a full 180 degrees viewing angle with increased brightness. They are available in all-red, blue or amber, or with red, blue or amber sides and a clear face. The clear face unit provides 43,000 candlepower of illumination.
The Si-tron is designed so that it will put out 75 watts with 11-ohm speakers presently in use and can be activated by buttons on the control panel, the vehicle horn rim, or a foot switch.

Thompson Carrier Company announces the Thompson Carrier, a rescue litter built to withstand the most rigorous use. According to the manufacturer, it can slide over the most difficult surfaces—rocks, sand, snow, debris—without damage. It can be dropped from a helicopter at significant altitude without effect.
Made of high-density polyethylene, the litter is impervious to moisture and chemicals and is nonconductive. It never needs painting because the orange color is molded into the material. X-ray pictures can bp taken through the polyethylene.
The carrier is easy to handle. The 3/8inch nylon rope that is laced around the upper edge provides a combination of tiedown points to secure the patient properly. Four corner hand holds provide sling attachment points.
Also available is a two-part model. It is rigid, virtually jam proof and easily assembled.

The 12-volt Omni-Sound electronic siren/amplifier from R. E. Dietz Company features four siren modes, including manual, wail, yelp and hi-lo, as well as public address and radio capability through the main siren speaker.
The solid state unit uses integrated circuits that reduce the number of components by 30 percent. Repairs are simplified since 90 percent of the circuitry is in a pull-out section and can be replaced in minutes.
Designed for auxiliary manual siren control from foot switch or horn ring, the Model 14-450 has a unidirectional microphone that eliminates background noise and feedback squeal. Mounted with a heavy-duty adjustable bracket, the unit measures 3 inches high, 7 inches wide and 7 1/2 inches deep. It has front lighting for night operation. Amperage draw is .50 amps standby with 100-watt peak siren power and 40-watt peak PA and radio power.

A new sidewall sprinkler design from “Automatic” Sprinkler Corporation of America provides a long-throw spray pattern of up to 300 square feet. This area coverage makes it possible to install a lower-cost sprinkler system with few sprinklers and fittings, less pipe, and frequently, reduced pipe sizes.
With the Series 38-3000 design, a single sprinkler can often provide protection for an average size room. It is offered in both bronze and chrome finishes, and the pipe flange and elbow can be painted for compatibility with room decor.

A helmet-mounted communications system to permit fire fighters to transmit and receive voice messages over approximately a half-mile line-of-sight range has been introduced by Mine Safety Appliances Company.
The battery-operated Topgard transceiver, which snaps into the crown ridge of MSA’s standard Topgard fireman’s helmet, eliminates the need for carrying conventional hand-held communications equipment.
A self-contained unit, the Topgard transceiver has miniature solid state electronic components attached to a contoured circuit board mounted on an impact-resistant helmet liner. Controls, nondirectional microphone and battery case are fitted into the liner brim, while the antenna is enclosed in a rubber guard around the helmet brim.
The transceiver is activated by turning an on-off squelch knob under the front brim of the helmet. A red light emitting diode located under the front brim, blinks to indicate the unit is operational.
The battery power source can be a mercury, alkaline or Ni-Cad rechargeable battery, or two 9-volt transistor batteries.

A series of thermal fire detectors for use with Pyr-A-Larm early warning fire and smoke detection systems is available from Pyrotronics, a Division of Baker Industries, Inc. These detectors are available for both Pyr-A-Larm low-voltage and high-voltage systems.
The detectors operate on the rate compensation/fixed temperature principle. The basic units include interchangeable plug-in models with exposed indicating lamps and surface-mounted units with or without internal indicating lamps, all of which are rated at either 125 or 200 degrees F. One series can be used with any fire alarm circuit of any manufacture using open-circuit, direct-shorting type units.
All models are Underwriters’ Laboratories listed and can protect up to 25000 square feet.

Fire Alarm Panels
Two control panels for use with Pyr-ALarm early warning fire detection and alarm systems have been announced by Prytronics, a division of Baker Industries, Inc. These panels, Models CP-2 and CP2E, are designed for noncoded, automatic systems with low voltage ionization, flame or thermal detectors and manual fire stations connected across a two-wire circuit.
Two-zone basic protection can be afforded by the CP-2 panel, and with the addition of the CP-2E extender panel, the system can protect up to six zones. As an alternative, modules can be substituted to provide municipal tie-in, leased line or supplementary relay operation to control a variety of external devices such as extinguishing systems, smoke dampers, ventilating fans, etc.
A maximum of 30 plug-in ionization, flame or thermal detectors can be connected to each zone. In addition, any number or combination of thermal detectors or manual stations may be tied into each zone. Both models are UL-listed.

Sno-Treds from the Detwiler Corporation, offer a solution to the winter traction problem.
They are a series of flexible bands, made of a durable polyurethane elastomer, which lie flat against the tire during regular driving. In snow, when the tires begin to slip, these harder-than-rubber, teeth-like bands twist downward into a “paddle-like” position that bite into the snow to provide the needed traction. The same principle applies in sand or mud. Because SnoTreds are harder than tread rubber, they also are effective on hard-packed snow.
Like chains, the bands are detachable and are intended for use only during snow emergencies. They are lightweight and can be installed in approximately two minutes without having to jack up the car, according to the manufacturer.
