Abstract: A coupling mechanism for interconnecting a drive spindle and a capping chuck, the mechanism including a coupling hub internally threaded for fastening to the spindle. A collar is disposed around the hub, and the hub has an arcuate groove in which a spring is positioned and retained by a removable plate. The hub has lugs integral therewith extending into receiving slots in a floating ring positioned in the collar below the hub. The floating ring is elliptically shaped for lateral movement relative to the collar along a first axis, and has feet integral therewith extending into keyways in a coupling member laterally movable relative to the ring along a second axis right angularly related to the first axis. The coupling member drives a chuck sleeve through a torsion spring to release the closure upon achieving a predetermined degree of tightness on a container.

Abstract: A hand held apparatus for the vapor polishing of plastic surfaces by movement of the apparatus over a plastic surface to be polished includes a body portion defining a vaporizing chamber. A container for plastic solvent, such as methylene chloride, is mounted on one side of the body for flow of solvent into the chamber when the apparatus is positioned with the container disposed above the chamber, with the solvent flow being interrupted when the apparatus is inverted to dispose the container below the chamber. A thermostatically controlled electric heating element is disposed in the chamber for vaporizing the solvent. An open-end guide tube projects from the opposite side of the body and is in fluid communication with the chamber. The guide tube opens downwardly when the apparatus is positioned with the container disposed above the chamber for directing the vaporized solvent to the plastic surface to be polished.

Abstract: A security system is disclosed which utilizes plural remote terminals for controlling access at plural locations throughout a secured area or building. Each of these remote terminals is capable of independent functioning, and includes a memory for storing plural independent identification numbers which define the personnel who will be granted access. These numbers stored in the terminal memories may be different from terminal to terminal, or may be uniform throughout the system, and may be the same as a list stored at a central processing location. Thus, access may be limited to the same group of individuals regardless of whether it is provided by a central memory list or a remote memory list. The remote memories provide total memory flexibility, so that the deletion of identification numbers from the list does not reduce the memory size.

Abstract: Apparatus for article deposit and/or removal from carrier cases and comprising a pair of endless carrier conveyors operatively positioned on an upper portion of a frame in adjacent parallel relationship for movement through a fixed course extending longitudinally of the frame; a plurality of positioning members or carrier bars for article grippers are operatively connected to the carrier conveyors for movement therewith, which positioning members extend transversely of the frame and have the article grippers depending therefrom; and a pantograph that extends longitudinally of the frame is present for each set of carrier bars corresponding to the array of articles in the cases to be processed, the pantograph has a leading and a trailing end with different ends being secured to different ones of the conveyors for movement therewith.

Abstract: Article packing or unpacking apparatus, including two correlated driven conveyors one for articles and one for moving cases through a fixed course having a horizontal section and with both conveyors having fixed orbits, the article conveyor being in a vertical plane above the one conveyor horizontal section; and article grippers are positioned by carrier bars engaged with the article conveyor, which grippers depend from the carrier bars in a lower reach of such article conveyor. A pair of control arms are individually secured to each carrier bar at different ends thereof to engage guides as the article conveyor is moved downwardly towards an inflection area so that the article grippers are presented on vertical axes as they are moved into, along with, and lifted from cases moving through the horizontal section of the case conveyor fixed course.

Abstract: A microminiature palladium oxide gas detector and its method of manufacture. The detector comprises an extremely small coil of extremely fine wire such as platinum which is retained, sealed and insulated with an amorphous ceramic binder. The detector further comprises a catalyst applied to its exterior surface. The detector is manufactured by winding the wire about a mandrel which is desirably molybdenum. The coil is then coated with the binder composition which preferably comprises reduced chromic and phosphoric acids. The binder is then cured to retain the coil and the mandrel is removed by etching or oxidation. The catalyst is then applied which is preferably palladium nitrate in a weakly acidic hydrolyzed solution which has been adjusted to a pH of about 3 with tertiary octyl amine. The catalyst is then dehydrated and calcined desirably using an automatic electronic pulse controlled machine to precisely adjust and control processing temperatures and times.

Abstract: A tip-up and mounting apparatus in a sortation conveyor includes a support angle, upstanding mounting angles, mounting brackets, and a tray engaging roller mounted on crank arms pivoted to the mounting brackets. The mounting angles are disposed with their apices facing outwardly of the conveyor, thus providing a mounting surface at 45.degree. to the conveyor's machine direction for the mounting bracket. The crank arms are pivoted to the mounting bracket, and this configuration provides an in and out component of motion to the rollers during their movement to and away from sortation tray engagement, thereby maintaining a short roller dwell time in tray interfering position. Adjustable construction of the components, together with a self-aligning actuating cylinder mounted within the mounting bracket reduces bulk and provides a highly tunable and smoothly operating tip-up apparatus.

Abstract: A zero pressure accumulating conveyor is provided from a standard belt driven live roller section and "bolt-on" accumulating elements. The accumulator includes a plurality of accumulation zones, each zone having an article sensing apparatus and frictional braking apparatus for braking at least one roller, and preferably less than all rollers, in the zone. Each sensing apparatus includes a first valve, actuated in response to an article in the respective zone for pressurizing the brake apparatus. All zones, except the downstream-most zone, have second valves. The second valves, in a respective zone, are opened in response to actuation of the first valve, in the immediate downstream zone, for passing the pressurized air from the first valve in the respective zone to the brake apparatus in the respective zone only when an article is sensed in the immediate downstream zone, and a subsequent article is sensed in the respective zone.
