Sitabkhan 2 FIBER OPTIC CONNECTOR     ABSTRACT OF THE DISCLOSURE   An actuated fiber optic connector is disclosed in which the plug and receptacle connector members are axially mated with the fiber optic ferrule in the plug connector member sliding into a V-shaped channel in the receptacle connector member with zero insertion force to abut the receptacle fiber optic ferrule therein. A leaf spring is mounted in the channel.  An axially slidable actuating sleeve is mounted on the plug connector member. When the connector members are mated, the sleeve engages a radially shiftable plunger in the receptacle, forcing the plunger inwardly to automatically urge the spring, and thus the ferrules, into the V-channel thereby precisely laterally aligninq the optical fibers in the ferrules.

Abstract: ABSTRACT OF THE DISCLOSURE:         A transducer for measuring vibrations comprising a ferromagnetic housing, a non-magnetic, low friction bush disposed within the housing, and an elongated movable per-manent magnet mounted for reciprocation within the bush.          This movable permanent magnet is suspended and reciprocable in a magnetic field formed by aligned fixed permanent magnets wich repel the movable permanent magnet, and has a central longitudinal opening therethrough aligned with a direction of reciprocation of this movable permanent magnet.  Two spaced coaxial induction coils are wound upon a coil shell, these coils and coil shell being disposed within and aligned with the central opening of the movable permanent magnet.          The respective ends of the movable permanent magnet overlap the respective inner, confronting ends of the coils when the movable permanent magnet is in a central position.  The ends of the movable permanent magnet is separated from the res-pective coils by radially narrow toroidal air gaps, the movable permanent magnet being freely movable with respect to the coils and the coil shell.  The fixed permanent magnets are preferably of toroidal shape.  The ratio  of the thickness of the bush   to the outer diameter of the movable permanent magnet may be within the range from 0,01 to 1,0.  This trans-ducer for measuring vibrations has far smaller dimensions that induction transducers known up to now and withstands big accelerations and vibration amplitudes.

Abstract: ABSTRACT      METHOD OF FABRICATING A SEMICONDUCTOR DEVICE A method for making a MOSFET device (20) in a semiconductor body (10) includes forming source and drain contact electrodes (12.1, 12.2) prior to growth of the gate oxide (10.3) and after formation of a high conductivity surface region.  The exposed mutually opposing sidewall edges of each of the contact electrodes (12.1, 12.2) are coated with a sidewall silicon dioxide layer (15. 1, 15.2), and the exposed surface of the semiconductor body (10) between these sidewalls is then etched to separate the high conductivity surface region into the source and drain regions (10.1, 10.2). Formation and etching of the high conductivity region may be omitted by using Schottky barrier or impurity doped material for the contact electrodes (12.1, 12.2).

Abstract: ABSTRACT    GAS OPERATED AUTOMATIC OR SEMI-AUTOMATIC GUNS       A gas operated gun having a receiver (1) including a rear wall (100) at one end and a barrel (10) at the other end and a bolt carrier assembly (3) reciprocal within the receiver is arranged to co-operate with a main drive spring (307) that urges the bolt carrier assembly toward the barrel.  The gun is designed so that in one aspect of the invention on an automatic cocking cycle the bolt overtravels the cartridge feed station by an amount equal to or greater than the overall length of a live cartridge.      In a further aspect, the gun is additionally designed using parameters calculated such that a substantially constant reaction is felt by a user.  The parameters involved are essentially the product of sprung weight (the total weight in kg. of all components driven by the main spring) x springing force (an average value of spring force that accelerates and retards the sprung weight) x cycling distance (the length of allowable travel of the bolt carrier assembly in meters) is equal to (0.5I)2 x 0.5g15% where I is the cartridge impulse and g is the acceleration due to gravity.  The length of allowable travel of the bolt carrier assembly is arranged such that the assembly does not impact a positive stop (100).

Abstract: ABSTRACT OF THE DISCLOSURE   The present machine is intended for the printing of selected characters on labels borne by a conti-nuous tape (13) passing over a print table (11) and driven by a chassis (22) imparted a reciprocating movement by the operating of a trigger.     In order to prevent the strip of labels from being pulled towards the outside at the time of the pulling off of the label said machine has a hand brake (28, 30) located in front of the print table.     This brake comprises a pivoting brake shoe (28) which is placed out of operation during the transport stroke of the continuous strip (13) by an interceptor (32) which is fastened to the transport chassis (22). This arrangement is established in order to permit a precise and effective braking action without requi-ring recourse to tolerances which are incompatible with mass production.

Abstract: ABSTRACT OF THE DISCLOSURE A method is disclosed of immobilizing actinide metal oxide ions.  A liquid composition is prepared of the actinide metal oxide ions and a monomer which is capable during electropolymerization of complexing with the acti-nide metal ions.  An optional polar solvent may be in-cluded in the composition if it is necessary to dissolve a solid monomer.  The monomer is then electropolymerized to form a polymeric complex with the actinide metal oxide ion.  The polymeric  complex  can be  separated  from the remainder of the liquid composition by the addition of a non-solvent for the polymeric complex which results in its precipitation.   Vinylimidazoles  have  been found  to  be suitable monomers for use in this process.
