Abstract: An improved lever arm for a tilt tray sortation conveyor has formula defined unlatching and tipping cam sections. The tipping cam section imparts a constant angular acceleration of about 20 radians/sec..sup.2 to the tray during positive tipping. Such angular acceleration produces a maximum tangential acceleration for any article on the tray, approximately equal to or less than the acceleration of a free-falling body. An improved tray latch or index plate has an inclined cam resisting rebound of the tray after initial tipping. Integral shock absorbers disperse impact forces in tray tip-up apparatus and resist elongation of tip-up mounting pin holes.

Abstract: An aerial apparatus swingable outwardly of a fire truck chassis is stabilized by outriggers on opposite sides of the chassis with the aerial apparatus being swingable to one side or the other only if an extendible section of an outrigger for that side has been moved relative to its base section from a storage position to a fully extended outrigging position on that side. The swinging of the apparatus to a side of the chassis is enabled by withdrawing stop means which is spring urged into the path of rotation of the apparatus to that side. The withdrawal of the stop means is actuated mechanically by means on the extendible section engaging and moving an actuating rod carried by the base section for the extendible section to effect operation of a linkage to withdraw the stop means against its spring bias. On retraction of the extendible section from its fully extended position, the spring urged stop means resets as the extendible section leaves the fully extended position.

Abstract: A fire truck includes an aerial ladder mounted on a rotatable base and outriggers on each side of the truck to stabilize the ladder in use. The outriggers may be deployed on only one side of the vehicle to permit use in confined areas. The ladder base is interlocked with the outriggers to permit the ladder to be positioned only on the side of the fire truck stabilized by the deployed outriggers. A retractable pin is connected through a mechanical linkage to each outrigger. Stop blocks mounted on opposite sides of the rotatable base contact any extended pins. Rotation of the base is thereby confined to a sector where the pins have been retracted by deployment of the associated outriggers. Small auxiliary jacks on each side of the fire truck are deployed in response to deployment of the outriggers on the opposite side of the truck. The jacks provide stability when the aerial ladder is used as a water tower for supporting a high pressure hose.

Abstract: A method of making a cast hopcalite filter. The filter is formed by adding to "green" hopcalite a given weight of ceramic fibers. Additional water may also be added as required. This mixture is blended briefly in a high speed blender and then poured into a mold. Water is drained by vacuum through a filter paper in the bottom of the mold, preferably with the aid of a vacuum. The wet preform is then placed in a high temperature (600.degree. F. to 650.degree. F. ) oven for approximately 90 minutes for calcining. In this process the basic catalyst material saturates the fiber matrix before drying and transformation into its final chemical state.

Abstract: A high flow sodium chlorate oxygen generator assembly (10) of a relatively small diameter. The generator assembly includes a chlorate candle (12) mounted within a containment vessel (14, 16, 18), the chlorate candle being provided with a deep conical recess (54) which is thinly coated with a rapidly combustible material (56). Ignition of the rapidly combustible material is achieved by extending a hollow ceramic tube (58) from a primer (38) located at one end of the containment vessel, the hollow tube directing the flame from the primer, when ignited, towards the center of the deepest part of the conical depression. The above construction provides a high surface area for burning, and also intensifies the heat flux within the chlorate candle thereby substantially increasing the rate of oxygen output over known chlorate candles of comparable diameters.
