Title: Switchable light fixture
Inventor: TAKANO TSUNESUKE
IPC: B60Q3/02
Filed: 1993-02-09
Abstract: A switchable light fixture which may be usefully be employed as an interior automotive lighting fixture includes an insulating plate defining an interior cavity in which a sliding piece is disposed and supports an opposed pair of lamp sockets for holding a lamp. A plurality of stationary parallel contacts (at least two of which form a pair of lateral stationary contacts, and one of which forms a middle stationary contact) are positionally held by means of recessed surfaces or channels defined between respective upright supports. A pair of lateral plugs each formed by an outwardly bent terminal end portion of a respective one of the lateral stationary contacts is positioned in a respective pair of the recessed surfaces or defined channels so as to be disposed over the lateral pair of stationary contacts, with a middle plug being portioned between the pair of lateral plugs. Each of the middle stationary contact and the middle plug includes a connector strip which is connected to a respective one of the lamp sockets. A switch cover which forms an upper extent of the cavity in which the sliding piece is disposed is provided with a unitary plug cover. The switch cover positionally holds stationary contacts, while the plug cover provides a protective cover over the lateral pair of plugs and the middle plug.

Title: Gear pump for high viscosity material
Inventor: GHOSH SYAMAL K
IPC: F01C21/02
Filed: 1993-02-09
Abstract: ABSTRACT OF THE DISCLOSURE         A pump 10 for materials having a viscosity up to about 3.0 x 105 cps, such as cellulose acetate, has a pump body 12 formed with a gear receiving means and, mounted thereon for closing the gear receiving means 13, a pair of side plates 16,18 having bearing receiving cavities 21.  The side plates 16,18 have pressure relief means 50 for relieving pressure that builds-up in the intermesh of gears 14 when highly viscous material, such as cellulose acetate, is being pumped.  This means of diverting the pressure buildup enables the pump 10 and component parts, such as shafts 22,24 and plain bearings 20, to resist premature failure due otherwise to the resultant load caused by residual pressure buildup.  In the preferred embodiment, wear resistant ceramic plain bearings 20 are press fitted in the bearing cavities.  Grooves or channels 30 in the interior walls 32 of bearings 20 provide a means to lubricate shafts 22,24 rotatably supported in the bearings 20.  Wear resistant coatings, such as, thermally sprayed tungsten carbide, are coated on the shafts 22,24 and surface 46 of side plate 16,18 to promote wearability and increased life of the apparatus 10.

Title: Oscillator with bias and buffer circuits formed in a die mounted with distributed elements on ceramic substrate
Inventor: BLACK GREGORY R
IPC: H03B5/18
Filed: 1992-06-08
Abstract: A voltage controlled oscillator and buffer amplifier circuit (211) is disclosed. The circuit is in a stacked configuration, whereby, the current from the power supply (361) is used by the buffer amplifier circuit and reused by the VCO circuit. The VCO circuit includes two transistors (333, 325). The transistors are set-up in a mirrored configuration, so that one of the transistors (325) controls the bias current in the other transistor (333). Both of the transistors are integrated into a semiconductor circuit die (365), thus, matching the thermal characteristics of the transistors (333, 325) and improving control of the bias current. The die (365) is bonded to a ceramic substrate (601). The substrate (601) has connectivity paths for connecting components in the circuit die to components external to the circuit die. Some of the connectivity paths are made of a material and length to form passive circuit elements.

Filed: 1993-07-30
Abstract: A method for the recovery of organic materials trapped in the emulsions generated in solvent extraction plants.  The emulsions are first washed in aqueous solution.  The washed emulsions are then subjected to a mechanical breaking process in aqueous/organic dispersion, inducing the inversion of the continuity of phases in the emulsions and the release of the phases involved.  Subsequent separation of the phases by decanting enables the removal of significant quantities of solids and increases the overall recovery of the organic trapped in the emulsions.
