Granted: 1983-02-08
Abstract: ABSTRACT           Penicillin sulfoxide esters are reacted with an iso-cyanate to produce the corresponding (substituted)-2-carbamoyl-oxyamethylpenam, the corresponding (substituted)-3-carbamoyl-oxycepham or the corresponding 3-methylcepham.  the 6- or 7-side-chain of these products may be cleaved to give the corresponding 6-amino (penams) or 7-amino (cephams and cephams) compounds, and the latter may be reacylated to produce different 6-acyl-2-carbamoyloxymethyl penams, 7-acyl-3-carbamoyloxy cephams and 7-acyl-3-methylcephams.  The substituent groups may be removed from the (substituted)-2-carbamoyloxypenams or the (substituted)-3-carbamoyloxycephams to give the corresponding free 2-carbamoyloxymethylpenams or 3-carbamoyloxycephams, respectively.  Novel penams and cephams provided by the present invention (after removal of the carboxyl-protecting group to produce the free acid) are active against various Gram-positive and Gram-negative organisms and, accordingly, are useful antibacterial agents for the treatment of diseases caused by such organisms in animals, including man.

Abstract: METHOD OF REMOVING HOSE FROM A MANDREL   AND A MANDREL ADAPTED TO THE METHOD             Abstract of to Disclosure A hose built on a non-expanding, non-collapsing mandrel is removed readily lengthwise of and off the mandrel facilitated by a tube of tough, flexible, thin anti-adherent film disposed in snug fitting contact with the length and girth of the mandrel.  The tube is secured to the rigid metal member only close to the end thereof from which the hose is removed.  Preferably, the tube is invaginated so as to provide inner and outer slidably juxtaposed walls.  The hose built on such mandrel is moved lengthwise together with the outer wall of the tube which slides on the inner wall or the metal member.  Lubrication, as by an air film, can facilitate the sliding, and does not contact the hose.  The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.

Abstract: ABSTRACT           In a snowmobile ski suspension each ski is carried on a trailing swing arm pivotally mounted in the front of the snowmobile.          The swing arm carries a steering tube in which the ski leg is pivotable about a generally upright axis.  A hydraulic damper-coil spring assembly is attached between a mounting on the lower end of the swing arm, and a bracket within the front part of the snowmobile, and controls upwards and downwards deflection of the ski assembly.  The skis on opposite sides of the vehicle are interconnected by a transverse torsion bar stabilizer which is arranged to transmit deflection forces from the ski on one side to the ski on the opposite side and vice versa, and thus enhance the roll stability of the machine.

Abstract: LANTY " A 2 22.            COMPUTER INPUT/OUTPUT ARRANGEMENT            Abstract of the Disclosure A computer input/output arrangement is disclosed which utilizes a rotate memory instruction of a computer instruction set for performing a bit by bit read/write data transfer between the computer memory and a connected peripheral device.  The arrangement enables the rotate memory instruction to perform read and write steps simultaneously from memory and the peripheral device. During the read step data is simultaneously read from the memory location and the peripheral device into associated locations in a computer register.  The register data is rotated such that the received data in the peripheral device bit location is rotated into the memory bit locations of the register while simultaneously rotating a memory data bit into the peripheral device bit location. The write step writes register data from the peripheral device bit location to the peripheral device while simultaneously writing the data from the memory bit locations into the memory.

Abstract: LAMPHOLDER HAVING TERMINALS OF THE INSULATION-DISPLAYING TYPE        ABSTRACT OF THE DISCLOSURE    A lampholder, of the type intended to support and supply electrical current to an incandescent lamp bulb, has terminals movable from normally retracted positions to positions in which they displace the insulation sheath of a current-supplying conductor wire, so as to make elec-trical contact with the conductive element of the wire.          On movement of the insulation-displaying terminals to positions in which they displace the wire insulation and make contact with the wire conductors, the terminals are latched automatically against retrograde movement.  Means is provided for facilitating the wiring of the lampholder to supply current either to single-filament or two-fila-ment lamps, whether in association with a single lamp of the single-filament or double filament type, or alterna-tively in parallel with one or more additional single or double filament lamps.  The lampholder can if desired be made as an interior for use in shells already standard in the industry, and in addition, is adapted to be made either with switches (for example, rotary turn knob switches) or alternatively, as a keyless device.
