Abstract: HYDRAULIC-ELASTOMERIC MOUNT Abstract of the Disclosure There is disclosed a hydraulic-elastomeric mount comprising a pair of mounting members that are interconnected by a hollow elastomeric body, an elastomeric diaphragm that closes the elastomeric body to form a closed cavity filled with liquid and a plastic partition and orifice assembly that divides the cavity into a chamber enclosed by the elastomeric body and a chamber enclosed by the diaphragm.  The partition and orifice assembly comprises a partition plate that actually separates the chambers and an annular plate having mating faces formed so as to cooperatively define at least one orifice between the plates extending in a plane along and adjacent the periphery of the plates with each of the plates further having an opening there-through to one end only of the orifice so that it interconnects the chambers and has a length which may thereby be made substantially as expansive as the periphery of the plates.  There is also a two-piece plastic damping decoupler assembly that fits together through and has a limited travel connection with the partition plate so as to effect limited cyclic volume change in the chambers and thereby permit limited vibratory amplitudes at low frequencies without hydraulic damping.

Abstract: Abstract of the Disclosure Improvements in the lateral recrystallization of semiconductor material on buried insulator are disclosed. In particular, in the zone-melting process applied to seeded Si, it is found that scanning the molten zone in a (110) direction can result in substantially subboundary-free recrystallized material. Furthermore, appropriate patterning of the capping layer, to provide means for accommodating the volume change attending solidification of the semiconductor material, can result in significant decrease of defect density in laterally recrystallized semiconductor material on insulator. Especially advantageous results are produced when combining the improvements.

Abstract: ABSTRACT        In a continuous casting apparatus, the level of liquid in the mold is monitored and compared to a desired reference level.  A microcomputer examines the resulting error signal and determines the amount of movement of a valve which would be appropriate to correct the detected error.  A control pulse is then generated having a duration corresponding to the desired movement distance, and the valve is adjusted accordingly.

Abstract: ELECTRICALLY SWITCHED FIBER                OPTIC DIRECTIONAL COUPLER                Abstract of the Disclosure This  invention  relates  to  an  electrically switchable   fiber   optic   directional   coupler.     Two oppositely oriented blocks of an interaction material are placed adjacent the fibers in an evanescent field coupler.          Application of an electromagnetic field to the interaction material increases the refractive index of one fiber and decreases the refractive index of the other.   The change in refractive indices of the blocks of the interaction material increases the propagation constant of one fiber and decreases that of the other fiber.   The coupling of optical signals between the fibers may be varied between zero and 100% by controlling the aplied field to change the  propagation  constants  between  values that  provide complete cross coupling of light from one fiber into the other  and  straight  through  propagation  provides  an electrically controllable switching action.

Abstract: REVERSING SWITCH FOR RECHARGEABLE HAND TOOL   Abstract Of The Disclosure A reversing switch for use in a rechargeable hand tool, the switch being located between the battery and the electric motor and being in direct contact with both.  The switch has an actuator privotally connected to an insulating mounting support which also holds two transfer terminals, one connected to each of two terminals of the battery, and a contact carrier which is rotat-ably connected to the support and coupled to the actuator in order to be rotated by the pivoting of the actuator.  Pivot contacts are attached to the contact carrier displaced from one another to provide a space for the parallel leads of the electric motor. Pivoting of the actuator reverses the connection of battery ter-minals to the motor leads and, accordingly, reverses the direction of the electric motor.  The transfer terminals have recharging contacts which are accessible through ports in the housing of the hand tool to allow recharging of the battery without removing it from the rest of the tool.
