  • Door set mounting
    Patent number: 4854620
    Abstract: A door set mounting including a baffle assembly formed of two circular sheet metal members arranged in face-to-face relationship, and a cylindrical tubular shroud also formed of sheet metal which extends around those members so as to be substantially coaxial therewith. Each circular member has a transversely extending channel formed therein and those channels combine to form a receptacle for a door latch housing. An opening formed through the base of each channel allows passage of a drive spindle for the latch. The two circular members are held in face-to-face relationship by a pair of clips, each of which straddles those members, and the same clips also serve to hold the shroud in assembly with the circular members. Preferably, the shroud is formed of two parts each of which is held by a respective one of the clips.

  • Novel copolycarbonate
    Patent number: 4855377
    Abstract: A novel copolycarbonate is provided, which comprises recurring units respectively of the formulae: ##STR1## in a molar ratio of units (A) to units (B) of from 9:1 to 1:9. The copolycarbonate has a number average molecular weight of from 300 to 50,000. The copolycarbonate is useful as a reactive polymer for producing final polymers such as a polyurethane and a thermoplastic elastomer. The copolycarbonate as well as various final polymers produced therefrom have excellent resistance to hydrolysis, light, chlorine, oxidative degradation, heat, etc. The polyurethane and the thermoplastic elastomer containing units of the novel copolycarbonate as soft segments exhibit remarkably improved flexibility and elastic recovery as compared to those of the conventional polymers.

  • Fluid containers
    Patent number: 4854343
    Abstract: Containers for storing fluids, especially carbon dioxide, under pressure comprise a tubular component (made of a deformable material capable of at least 7% elongation before fracture) which is preferably closed by a top plug with a filling/emptying device (and any end plug) by crimping open end(s) of the component over a circumferential shoulder on the plug(s). A primary pressure relief device comprising a poppet with a piston section, a return spring and a control (exit) orifice tolerates and ejects dirt, prevents the formation of solid phase material and vents the contents in brief spurts so as to minimize loss. Desirably, a narrow helical conduit connects the primary pressure relief device to the container interior and, by being in thermal contact with the tubular component, chills the contents during venting so as to minimize loss.

  • Hydraulic valve actuating device
    Patent number: 4852852
    Abstract: A 2-port, 2-directional hydraulic valve is disposed alongside a pulse generator in a casing, the actuating force of the pulse generator being transmitted to a push rod of the valve for actuating the latter via a two-armed lever mounted like the beam of a balance. A threaded bore in one lever arm receives a bush which is adjustable in the direction of actuation and contains a spring-loaded pressure member. A set screw can be used to pre-stress the spring and thus exactly adjust the transmitted actuating force, while the adjustable bush is used for pre-setting the actuating travel.

  • Piston wrist pin installation and removal device and method of using
    Patent number: 4852231
    Abstract: A device for installation and removal of a wrist pin from a piston includes a press pin having an upper end for engaging a hydraulic ram and a lower end section of reduced diameter which engages into the bore of the upper end of a wrist pin. The lower end of the wrist pin is engaged by an end section of reduced diameter of a guide pin, the end section of reduced diameter having at least one groove encircling its circumference and having an O-ring engaged in the groove. The press pin, wrist pin and guide pin engage together to form a substantially rectilinear rod-like structure, enabling the wrist pin to be inserted through the shaft of the piston and eye of the connecting rod without damage to the shaft.

  • Toy for demostrating magnetic force and the effects of air pressure
    Patent number: 4852497
    Abstract: In a magnet-floating toy running inside a loop of vacuum-like state, a .perp. shape monorail is provided within a loop of air-tight, transparent round pipes, air within the loop is drawn by suction to make loop reach a vacuum-like state to reduce air resistance. In the two extended wings of the monorail and also underneath the surfaces of the car body, permanent magnets are installed and are arranged so that the magnet poles of the two magnets are the same to induce repulsion force and that when the car rides on the monorail, it may float. Power is supplied from source outside the loop to the conductive rail mounted in the top surface of the monorail and through the brush, then in turn, transmit to the motor. Thus motor will enable car to run within the loop.

  • Ash conveyer
    Patent number: 4848535
    Abstract: A conveyer for moving elements along a pan is disclosed. The conveyer uses a pivotally-mounted scoop carried by a trolley which rides on a track running beside the pan. When moving in the forward direction, the scoop is pivotally rotated to engage the bottom of the pan and move the articles along the pan. When moving in the reverse direction, the scoop is rotated so that it does not engage the bottom of the pan to allow it to move rearwardly whereupon another forward motion occurs. At the upper end of the pan, the track moves at an increased angle to cause the scoop to pivot into a position whereby the articles are more efficiently pushed over the edge of the pan.
