Abstract: A conveyor carries cans or other refuse from a source of cans to a jaw crusher. The conveyor is adapted to drop cans generally one at a time into a bin, and the bin has an opening to release each can when the jaws open to receive it. In the open position, the jaws are spread far enough apart so that the can drops to the bottom thereof. A flap is provided at the bottom to hold the can between the jaws. The end of the flap extends to a position above the bottom of the stationary jaw. As the jaws come together in crushing, the moving jaw cams the flap downward along the stationary jaw. However, the flap is not cammed entirely out of the area beneath the jaw until the jaws have come together to hold the can. The flap ensures that no lip is formed on the can. After the jaws close, the flap is moved out from beneath the jaws so that when the jaws open, the crushed object can fall out of the jaws for carrying away.
Abstract: An improved fluid spray head for sprinkler apparatus is disclosed adjustable both as to the flow rate of fluid to the discharge orifices and the precipation rate over the ground area sprayed, and particularly adapted to spray a specifically shaped non-circular area. The spray head has a plurality of circumferentially-spaced discharge orifices having cross-sectional areas equally proportional to the square of the distance that their respective spray streams are desired to travel whereby the perimeter of the ground area sprayed defines the preselected shape and receives a substantially uniform coverage of fluid.
Abstract: An apparatus and method of controlling and abating gasoline vapor emissions which occur at a gasoline service station during transfer of liquid gasoline from a gasoline supply tank truck to underground storage tanks at the station and also during transfer of liquid gasoline from the underground storage tanks to the gasoline tank of an automobile through a service station gasoline pump. Vent outlet pipes of the underground storage tanks are manifolded to a common vent pipe where vapor pressure is sensed by a plurality of preset pressure sensing means to direct vapors from the vent pipe to a burner means under predetermined below atmospheric pressure or vacuum conditions. A compressed air source provides pressure air for directing the gasoline vapors to the burner means as by suction pumping and to also actuate valve means in the gas vapor line to permit flow of vapors to the burner means.

Also provides an apparatus which embodies a novel combination of mechanical improvements which overcome problems of weight, stability, flexibility, durability and dependability under various field conditions, and which employs the mode of operation above referred to.
Abstract: Method and apparatus for decoding and duplicating a key wherein the notches in the shank of the key are coded to a predetermined coded depth and spacing therebetween. An index card having a sequential index thereon corresponding to the predetermined coded depth is inserted into a housing and the key to be duplicated is inserted into a slot in the housing where it engages an indexing member which enters one of the notches on the key and indicates on the card the coded depth of that notch. The angle of cut of the same notch may also be determined. The remaining notches of the key may be decoded in like manner. The same index card is then inserted into a housing associated with a grinding wheel. The depth of the cut made by a grinding wheel on the blank key is indicated on the card by a pointer pivotally secured in the housing.In an alternate embodiment, the same index card is inserted into a housing and the position of the key to be duplicated is calibrated with respect to the grinding wheel.

The inertia-responsive member is adapted for moving into the seat back locking position during a vehicle deceleration. The latch mechanism further includes a device for maintaining said inertia-responsive member in its seat back locking position subsequent to said vehicle deceleration. The seat back latch mechanism may also include a device for releasing said seat back from its locking position subsequent to said vehicle deceleration.
Abstract: A stablized gasoline powered model airplane and pylon assembly has a thin vertically extending pylon of substantially uniform cross-section, a base for supporting the pylon vertically without circumferential lateral interference, a gasoline powered model airplane mounted for powered flight around the pylon by a small ring freely mounted on the pylon and a restraint line extending between the model airplane and the ring. A circular element of resilient plastic is secured near the upper end of the pylon for engaging the ring on the restraining wire to limit vertical travel, and oscillation of the model during flight. The model airplane is constrained to take-off, circle about the pylon, climb to the height of the pylon, and, following engagement with the flexible damping and stop element, to continue circular flight about the upper end of the pylon until fuel is exhausted and then to glide to a landing.
Abstract: The present test apparatus is connected to a jet engine to perform a large number of tests of the mode of operation of the jet engine on both a static and dynamic basis. The multifunctional tester includes four sets of numerical displays on the face of the instrument. The first of these displays shows a sequence number and represents the specific test sequence which is being undertaken by the test apparatus at a particular time. An advance switch is provided to advance to the desired test sequence; and the initiate switch which starts the displayed test sequence. Both the advance switch and the initiate switch have indicator lights associated with them indicating that the test apparatus is ready either to have the sequence advanced, or to initiate a test represented by the sequence number. Input switches are also provided on the face of the test instrument for entering the trim RPM for the particular jet engine under test.

Abstract: A small lightweight hand-held data processing terminal is provided with several visible field display registers, one entry register, and a keyboard. When used by a route salesman, for example, the salesman initially enters information from the keyboard into the entry register, and then upon verifying that the information is accurate the salesman shifts the information up to the individual field registers which might for example relate to product code information, the number of units which are being purchased or sold, the type of transaction whether it is cash, check, credit card, or the like, and other desired information. The transaction information is initially entered in the entry register and is then shifted up to the appropriate field register. Finally, the customer identification number is entered in the entry register, the entire transactional entry is rechecked visually, and then entered into storage.
Abstract: The invention relates to a correcting device for controlling the normal operating speed of an automotive engine with a variable speed transmission.The variable speed transmission incorporates a hydraulic control mechanism of which a movable member is connected to the actuating member of the speed reduction ratio control device, and is capable of being placed in communication selectively with a pressure fluid source and a reservoir through a distributing valve. A slide of the distributing valve is so connected that their actions oppose one another to a centrifugal governor and a resilient member connected to the acceleration control pedal of the vehicle through a pivotal lever. A movable part is connected to the speed reduction ratio control device and is disposed opposite the lever and serves as an abutment limiting the pivotal movement of the lever.
