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.

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.

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.

Abstract: A lock mechanism for a rotatable stub such as the operating shaft of a fluid flow control valve has a main body 10 connected to a drive member 12 adapted for mounting on the rotatable stub. A locking sleeve 17 is adapted to fit closely to the machine (e.g. valve) on which the mechanism is fitted so as to be held against rotation, and mounted in the body are two key-operated lock members 25 engageable with the sleeve 17 to lock the body against rotation. Associated with each lock member 25 is a control plate 56, movement of which can be blocked by a stop member 53 so preventing operation of the associated lock member 25. The two stop members 53 are threaded on studs 55 fixed in the body 10, and are moved linearly on being rotated by respective toothed wheels 46, driven by a peg 62 on sleeve 17 as the body 10 is rotated.

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.

Abstract: A depth-type filter cartridge comprises an elongated fluid-conducting core, and a plurality of filter cells mounted generally parallel to one another along the length of the core. Fluid to be filtered passes from the exterior into the interior of the cells through a filter medium, and then from the interior of the cells into the core. Support for the filter cells to prevent distortion or damage when used under extreme conditions is provided by external filter cell separators which coact with the cells and are mounted radially about the core between each pair of adjacent cells.

Abstract: An inflatable bladder and extendable diaphragm are affixed within the cap of a standard liquid container. The shaft and brush for removing the liquid from the container are attached to the diaphragm portion. The bladder can be compressed in a variety of ways manually and thereby causing the diaphragm portion to extend, moving the shaft and liquid pick-up means so that the liquid at the bottom of the container can be easily removed.

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.

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.

Abstract: A secondary containment tank and ground level manhole cover provide access to a fill pipe for a main underground storge tank and prevent overflow of excess volatile liquid such as gasoline into the ground. The containment tank includes an upper ring or rim secured on an in-ground vertical skirt supported in a concrete base. An inner container is secured to the vertical skirt and has an open end adjacent to the upper ring. The cover fits into and is supported on a horizontal flange or step of the upper ring over the opening of the inner container and includes a vertical ring extending downwardly from the underside of the cover into a space between the inner container and vertical skirt. The vertical ring on the cover extends below the level of the container opening and thus bypasses any surface water leakage through the upper ring around the cover into the space adjacent to the container and into the ground below.

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.
