  • Patent number: 4731042
    Abstract: The disclosed toy may be used for capturing an intended toy victim within a snare net sufficiently large when opened to fit over and around at least part of the victim. A carrier, shaped as a monstrous insect or the like, may be used for holding the net open while stalking the victim, for positioning the net over and down around the victim, and for releasing the net when desired to snare the victim. The carrier may have a body and a plurality of legs depending from the body in an array to fit at least partially down and around the victim. Corresponding free ends of the legs have means for receiving and removably holding the snare net, to hold the same opened. The net may be elongated and generally tubular in shape, having a closed end and an open end. Flexible elastic means at the open net end, may be stretched to the holding means on the legs; and when released, may resiliently close the open net end against and relative to the victim.

  • Patent number: 4719686
    Abstract: A method of repairing an end-of-car cushioning device for railroad cars is disclosed. The cushioning device is of the type having a piston and a shaft connected to the piston. In such devices, the shaft may become damaged with wear. In the disclosed method of repair, the old piston and shaft are removed from the cushioning device. The old shaft is substantially removed from the piston. The piston's true center is found, and a bore is cut through it. The bore is threaded, and an angled chamfer is cut in one end of the bore. A new shaft is provided with a threaded portion, the threads being adapted to mate with the threads of the bore. The shaft also has an angled chamfer adapted to mate with the bore's chamfer. The new shaft is connected to the old piston so that the threads engage and the chamfers abut.

  • Patent number: 4669738
    Abstract: A package seal particularly suited to pumps or other applications having a drive shaft which terminates internally of a housing at its connection to the impeller or fluid working element. In such an apparatus partial disassembly of the components provides access to the free end of the drive shaft. The package seal has an outer member adapted to be disposed coaxially on the rotatable shaft and pass through the housing bore. The outer member includes a mounting flange adapted to be secured in the interior of the housing and a cylindrical body adapted to extend axially along the rotatable shaft from the seal flange to the exterior of the housing. The cylindrical body houses the seal components which provide a fluid tight seal between the housing and shaft.

  • Patent number: 4639236
    Abstract: A toy formed as a small vehicle which is propelled from a simulated explosive such as dynamite. The simulated dynamite is inserted in the rear of the toy. The toy vehicle is released from the simulated explosive by a cable attached to a plunger type detonator. The insertion of the simulated dynamite into the vehicle compresses a spring which drives the vehicle away from the simulated dynamite on actuation of a release mechanism.

  • Patent number: 4635798
    Abstract: An apparatus and method utilizing pressurized air discharged through nozzles to segregate a mixture of elements having either different geometrical characteristics or different masses. The mixture is placed in a container having a conveyor track, and is forced to move along the track, across a primary nozzle which forms the mixture into a single layer. The mixture then moves across a blow-off nozzle which propels one set of elements off the track and out of the container while the other remains within the container. A two stage separation may be used to optimize efficiency.

  • Patent number: 4624482
    Abstract: An elongated sheet of printed material for a roll stamp dispenser having formed flaps serving as driving sprockets and also having perforated score lines for tearing the stamp from the dispenser. A plurality of partially cut spaced apart flap groups formed of flaps along transverse lines mate with driving pins on the roll stamp dispenser. The flaps remain in tact with the stamp roll so as not to destroy the printed appearance of the stamp roll. Perforated transverse continuous score lines are formed at predetermined positions along the longitudinal length of the roll for use in separating adjacent sections of the roll as desired.

  • Patent number: RE32386
    Abstract: Improvements in sprinkler systems having fluid under pressure flowing therethrough and a sprinkler head with a pop-up nozzle actuated by fluid pressure. An impeller is actuated by the fluid flow to rotate the nozzle and thus rotate the spray of fluid therefrom. A transmission is disposed between the impeller and the nozzle for transmitting rotation of the impeller to the nozzle. The transmission is sealed off from the fluid passing through the system by a resilient expandable diaphragm at one end. A fluid pressure responsive seal is provided in the system in sealing engagement with the nozzle. The sealed-off portion of the transmission is completely filled with a lubricating medium which is free to selectively contract or expand against the diaphragm in response to varying ambient conditions encountered by the sprinkler head. The nozzle may also include means for varying the pattern of the sprayed fluid and may be comprised of molded plastic components which may be assembled together.
