A second three-input AND gate coupled to the output of the first three-input AND gate and a highest axle speed signal terminal. A minimum axle rate discriminator circuit connected to each of plurality of axle rate signal terminals of the multiple axles of the railway vehicle. A brake cylinder pressure circuit check and a brake cylinder pressure signal generator coupled to a truck brake cylinder pressure signal terminal.

Abstract: A safety or pressure relief valve which relieves excessive pressure in a storage reservoir in a compressed air system. The valve includes a lower valve body and an upper valve housing. A valve seat member is secured in the lower valve body. The valve seat member includes an annular dovetail groove for accommodating and retaining a fluorocarbon rubber O-ring seat. A valve disc and stem slidable within a stem guide member located in the upper valve housing. A compression spring for urging the valve disc against the fluorocarbon rubber O-ring seat to positively seal off the flow of air between an inlet and outlet port.

Abstract: An interslip sequence slip control system for multiple wheel axle units for railway vehicles including an electronic logic network for determining whether all the axles of the vehicle are slipping at the same time. A first circuit for selecting the maximum axle speed on the vehicle and a second circuit for selecting the minimum axle rate on the vehicle. A converter circuit for increasing the bit size of the maximum axle speed signal. A plurality of calculating circuits for producing a speed reference signal. An interslip sequence circuit for supplying the maximum axle speed signal to a reconversion circuit when at least one axle is not undergoing slippage and for supplying the speed reference signal to the reconversion circuit when all the axles on the vehicle are slipping.

Abstract: A latchable safety protection device for covering the cassette receiving opening of a cassette tape recorder for preventing the introduction of foreign elements into the recording chamber in which the device includes a plastic body having an integral hollow insert portion and cover portion. A pair of spring biased latching members which engage the sides of the cassette receiving opening, and a pair of slidable release members for retracting the spring biased latching members to permit the withdrawal of the device from the cassette receiving opening to allow the insertion of a tape cassette.

Abstract: An automatic car coupler control system for a railway train consisting of at least one powered car and at least two nonpowered cars. An electrical switch and a timer carried by the nonpowered car following the powered car is connected to a voltage source located on the powered car. An electrical switch and a timer carried by a subsequent nonpowered car is connected through the electrical switch of the nonpowered car following the powered car. The timers of each of the nonpowered cars is connected to a plurality of electromagnetic valves which pneumatically actuate the head pistons of the couplers when the nonpowered cars meet and which initially pneumatically actuate the head pistons and the head unlocks of the coupler and which subsequently pneumatically activate a latch cylinder on the coupler on the nonpowered car following the powered car when the nonpower cars are uncoupled by actuating the electrical switch on the nonpowered car following the powered car.

Abstract: A bullet for muzzle loading black powder rifles having an elongated cylindrical metal body. The metal body includes a front paraboloidal segment and a recessed base. A rear expansion band for initially guiding the bullet into the rifled bore and for tightly sealing the explosive gases upon firing of the rifle. A front rifling band which is cut by the lands of the rifling to cause rotation about the longitudinal axis of the bullet. An intermediate knife-like cleaning band which removes residue from the rifled bore as the bullet is propelled outwardly by the explosive gases.

Abstract: A static-type of multi-color searchlight signal for displaying one of a plurality of color signals including a plurality of parabolic reflectors, each having a focal point at which an associated "white light" source is located so that light rays are collected and reflected in a substantially parallel configuration, a plurality of color filters, one of which is disposed in front of each one of the plurality of parabolic reflectors for passing a given color of the parallel light rays and for absorbing all other colors, a plurality of dichroic filters situated in the optical path of the passed parallel light rays and having an angle of incidence which corresponds to the angle of incidence of the passed parallel light rays, and a lens system for projecting the passed parallel light rays for providing a color signal aspect.

Abstract: A forearm rest for assisting an angler in holding a spinning type of fishing rod and for allowing the angler to freely cast without hinderance. The forearm rest includes a long narrow arcuate portion extending outwardly from the handle for accommodating the forearm of the angler and includes a handle attaching portion for secure connection to a desired position along the handle of the fishing rod.

Abstract: This disclosure relates to an elevational and windage adjustable sight rifle mount for readily and rapidly attaching the scope to the rifle and for quickly and easily detaching the scope from the rifle. The mount includes a pair of spaced saddle assemblies fixedly secured to the receiver housing of the rifle. One of the saddle assemblies includes an inclined contact edge while the other assembly includes a flat deformable leaf spring. The scope is clamped to an elongated carrier having one end formed with a sloped or oblique surface which matches and engages the inclined contact edge and having the other end provided with a pivotal lever. One end of the pivotal lever includes a digital tab for being manipulated from an unlocked position to a locked position while the other end of the lever includes a rounded portion which frictionally engages a locking ledge and deflects the leaf spring to positively lock the scope to the rifle.

Abstract: This disclosure relates to a versatile lightweight rifle rest having a pointed upstanding rod member and a step-on member for affixation to the ground and having an adjustable two-point contact cradle member for supporting the entire rifle and being readily positive positioned along the length of the upright rod member and being quickly and easily angularly rotated and elevationally pivoted to effectively sight in the rifle on a target.
