Abstract: Abstract This disclosure relates to a method of rotating priorities among stations on a communication channel, and particularly on a contention channel where a plurality of active stations are provided, each capable of seizing use of the channel.  A counter device at each station contains an indication rep-resentative of the station having highest priority to the channel.  Each station establishes a priority rank for itself based upon the contents in the counter device.  The indication is sequentially altered to provide priority to other stations.  The priority indications in the counter device are synchro-nized each time a station seizes use of the channel, and may also be syn-chronized periodically if no station seizes use of the channel.

Granted: 1984-02-07
Abstract: ABSTRACT   This invention relates to a device for detecting the tape end of a magnetic recording apparatus in a sure and reliable fashion, which thereby permits the tape to be automatically stopped. The device uses a photo-transistor incorporated into a positioning pole in the cassette and a light-emitting diode opposing this phototransistor.  The two elements cooperate to detect the lead tape connected to the tape to ensure detection.  An additional advantage is that the phototransistor is incorporated and requires no extra space for installation.  The device is accordingly easily incorporat-ed into existing magnetic recorders such as video tape recorders.

Abstract: ACTUATING MECHANISM FOR FLUID   PUMP INLET CLOSURE VALVE              ABSTRACT OF THE DISCLOSURE       This invention relates to an actuating mechanism for a pump inlet closure valve and includes in combination a pump housing which projects into a fuel tank and has an opening to allow passage of fuel from the tank into the pump housing.  A pump inlet closure valve sleeve is positioned within the pump housing and is mounted for movement in a predetermined path.  A pump is positioned within the valve sleeve.  A fixed pump housing seal is located in the path of the valve sleeve as well as within and between the pump and the housing.  A valve actuating mechanism includes a handle which is pivotally secured to the pump housing and slideably moveable in a direction parallel to the path of the valve sleeve.  The handle is mechanically coupled to the valve sleeve whereby initial manual movement of the handle causes the valve sleeve to move into a position blocking the opening to the fuel tank.  The valve sleeve is locked in place during subsequent pivotal movement of the handle, which movement allows for the unobstructed passage of the pump from the housing.

Abstract: ABSTRACT    A device comprising a unit, preferentially of microcomputer type, which detects traffic and controls the functions of a PABX. A computer equipment is connected to or from a part of the unit for interworking with it. The computer equipment has a terminal (A1) at an operator's position, intercept or equivalent position, the terminal being arranged to display information relating to the PABX interception facility. A PABX extension enters information about his own interception by making a call by dialling a predetermined code. His number and the code are stored in the unit. A subsequent call to the self-intercepted extension causes the unit to transfer the caller to an operator or other attendant and to give on a display on the terminal at the operator' s or other attendant's position a standard information preprogrammed in the computer equipment and of the extension number.

The stand includes a central, disc-shaped hub portion which interlocks vertically and horizontally with a plurality of radiating, tapered legs, with the component parts so configured that, when interlocked, they cannot be separated under load, or loosen or "wobble" with respect to each other. The component parts are comprised of substantially rigid thermoplastic resin material with a slight degree of resiliency, such as high impact polystyrene, so as to provide a gripping action between the parts when they are joined. The legs are connected to the hub portion with a tongue and groove arrangement connectable from the bottom of the stand upwardly, so that applied loads from above serve to urge the tongue and groove joints into a fully seated and totally stable condition.

Abstract: Abstract A rotary internal combustion engine is herein disclosed consisting of an annular rotating block with a cylindrical exterior wall and an interior wall formed with a plurality of radially arranged, inward opening, eliptical chambers housing a plurality of revolving eliptical pistons, each with a geared track which meshes with a geared track on a roller mounted on a central rotating driving shaft journaled through disc-shaped walls attached to the sides of the block.  The pistons are held in sealed contact with the interior wall of the block by the geared roller, and in sealed contact with the disc-shaped walls by spring-loaded rings on each side of the pistons.  The block, together with the attached disc-shaped walls and the central driving shaft are held by an annular stationary casing with spark-plug mounts, intake and exhaust ports, and roller bearings on the inside cylindrical wall. Ports at the apex of each eliptical chamber in the rotating block register successively with the spark plugs and the intake and exhaust ports.  A spur gear mounted on the driving shaft, between two walls respectively attached to the block and the casing, meshes with gears mounted on that wall attached to the casing, and these mesh with a ring gear attached to the block wall, such the the block rotates a radial distance of one chamber while the pistons revolve 180°.  If the block and pistons rotate in a counter-clockwise direction, the driving shaft together with the geared roller rotate in a clockwise direction.      In certain embodiments of this invention, the chambers and the pistons may be on any number of shapes other than eliptical, provided that the centrally mounted roller is corres-pondingly shaped such that the piston, or a lobe of the piston, may penetrate successive chambers and revolve in sealed contact with the walls of the block.  The invention may also be modified for use as a compressor or pump.

Abstract: PROCESS OF FORMING FOUNDRY CORES AND MOLDS UTILIZING BINDER CURABLE BY FREE RADICAL         POLYMERIZATION                       ABSTRACT        A binder is formed by polymerizing or hardening a binding material or composition, an unsaturated polymer or unsaturated monomer or mixtures thereof (polymer solution), wherein at least part of the unsaturation is ethylenic, preferably of vinyl or acrylic type, by free radical polymerization.  The free radical polymerization is caused by contacting the unsaturated binding material with a free radical initiator comprising a peroxide and catalytic agent.  In the preferred embodiment the binding material is a solution of an ethylenically unsaturated polymer in a solvent of unsaturated monomeric compound or compounds, in which vinyl or acrylic unsaturation is present.  The binder is formed upon poly-merization which occurs when the unsaturated monomer, polymer or polymer solution is exposed to the free radical initiator.  Sub-jection of the unsaturated monomer, polymer or polymer solution to the initiator begins the formation of free radicals and sub-sequently the binding composition is polymerized to form the binder.  This binder has been found to be especially suitable as a foundry binder of the cold box type wherein a room temperature, rapid gas cure is utilized.  The gas, preferably sulfur dioxide, serves as the catalytic agent of the free radical initiator.     Cores made using this binder are especially useful in casting aluminum and other lightweight metals because the binder collapses readily after casting of these metals to provide complete shake-out of the core without application of external energy.  The binder also has application to make cores used in casting iron.
