  • Patent number: 4772170
    Abstract: A method of stacking boxes, cases, cartons, crates or the like using a computer-controlled apparatus having a lifting grab fitted with two independently movable grippers between which a box to be lifted may be clamped. In a first step, the grab is positioned at a loading station, the grippers are relatively separated and then the grab is lowered over the next box to be stacked. One gripper is then moved to a datum position and the other gripper is moved towards said one gripper so as to clamp a box therebetween. The grab is raised and moved together with the clamped box to a stacking station whereat the grab is finely positioned to have the box correctly placed in the stack under assembly with said one gripper alongside a previously stacked box. The lifted box is released by moving said other gripper away from said one gripper and then the grab is raised clear of the stack without disturbing the placement of the last-lifted box.

  • Patent number: 4731009
    Abstract: Spring-loaded rollers for a mold have a sealed axle mount which passes through the roller into a supporting portion of the seats in the platen to prevent the roller from rotating, twisting or otherwise moving in the seat in the roller assembly and in the mold. The roller assembly is easily removed from its seat through the use of a removal device cooperating with screw threads in the roller. A plurality of rollers are used to permit a mold to be easily moved into and out of position in a press. The mold is thus mounted in position since the rollers limit the ability of the mold to move laterally. The seals are dished TEFLON disks which overfit the axle and interfit either against the sides of the roller or within slots cut circumferentially on either side of the roller. The walls of the slot may be undercut and/or otherwise shaped. The invention makes it very easy to move the heavy molds into and out of the press thereby reducing operator fatigue.

  • Patent number: 4723673
    Abstract: A cap assembly for a threaded neck of a container includes an inner threaded cap which fits closely within an outer cap that is rotatable about the inner cap within defined limits. The outer cap includes a transparent window through which means are displayed to provide a positive indication of a prior usage or tampering. In one embodiment, a drive bar and a series of breakable fins on the outer cap seen through the window are moved into contact with a break and open bar on the inner cap. After the fins are broken, the drive bar engages the break and open bar to permit rotation of the inner cap with the outer cap and removal of the assembly to open the container. Replacement in the opposite direction causes the drive bar to engage a close bar on the inner cap to reseal the container while the broken fins remain visible. A second embodiment has an indicator sleeve instead of fins with a second drive bar to move a SAFE indicia in view of the window during the opening rotation.

  • Patent number: 4716262
    Abstract: A shielded electrical switch includes a pressure-actuated switch comprised of three layers, the top and bottom layer of which are electrically-conductive and the intermediate layer of which is a spacer layer containing apertures at the switch points. A sealing membrane is coupled over the layered switch, the membrane having thickened push-button supports overlying the switch points. The thickened push-button supports are spaced from the membrane via frustro-conical mounting portions on the membrane. This frustro-conical mounting gives the buttons the sufficient "feel" or resistance when depressed, and also insures that the switch-actuating portions of the membrane will make contact with the upper surface of the switch to insure that the switch points of the upper and lower layers of the switch will make contact via the intermediate layer. The membrane and the sealed, layered switch are, in turn, enclosed in an armored, sealed push-button enclosure.

  • Patent number: 4687134
    Abstract: A railway fastening, especially adapted for securing a bridge girder or cover plate of the girder to a cross-tie on a bridge, or like supporting structure, is in the form of a resilient clip having a substantially planar body portion with an opening for a bolt which is offset with respect to the resilient end engaging bridge girder. The resilient end in the form of a compression arch engages a girder flange to limit vertical movement and a tie-engaging end includes downwardly and outwardly extending ears for laterally restraining the cross-tie. A shoulder on the resilient end also engages a side of the girder flange to further limit lateral movement. In order to provide greater resilience, the arch can be in the form of two separate finger portions joined at the base with the body portion to form a U, each of the finger portions having a lip adapted to overlie the girder flange. A projecting lug adjacent to the opening for the bolt is provided to facilitate securing a bolt tensioning member, i.e., a nut.

  • Patent number: 4682511
    Abstract: A CVT combined with a gearshift mechanism to permit shifting of power flow under conditions of zero load and synchronous speed. The CVT can adjust the output speed within a gear ratio without resetting of the CVT ratio during a shift. The full speed range of the CVT is matched by two planetary drivetrains having normal and inverted characteristics and driven by two shifting gearboxes. Input power is divided into three paths to drive a central CVT and the two shifting gearboxes. The output of one of the gear-boxes is clutched to the normal input of a compound planetary drivetrain and the output of the other gearbox is clutched to the inverted input of the compound planetary. The CVT is coupled to the sun gear input of the compound planetary with the output of the compound planetary providing the output of the gear-assisted CVT. Operation occurs with either of the two clutches engaged to a respective input but not both, so that each gearbox may be shifted when its output is disengaged.

  • Patent number: 4640009
    Abstract: A tool for preparing the end portion of a co-axial cable has a blade which may pivot between two limiting positions, in one of which the cutting edge of the blade lies across a cable-receiving opening to a greater extent than in the other of which positions. On inserting a co-axial cable through the opening and rotating the tool around the cable in one sense, the blade is caused to move to one limiting position so effecting one depth of cut, but on rotating the tool in the other sense around the cable, the blade is caused to move to the other limiting position so effecting a different depth of cut. In this way, the different layers of the cable may be severed and removed.
