Title: Bearing assembly for a shaft journal
Inventor: WILLIAMS SAMUEL R
IPC: F16C35/063
Filed: 1991-03-26
Abstract: ABSTRACT A bearing assembly fits over the journal at the end of a shaft and is clamped between a fillet at one end of the journal and an end cap which extends across the opposite end of the journal.  The bearing assembly includes a double row tapered roller bearing having two indirectly mounted cones, a double cup around the cones, and tapered rollers arranged in two rows between the raceways of the cones and cup.  The bearing assembly also includes seal rings located against the cones and seals fitted into the end of the cup and cooperating with the seal rings to establish barriers at the ends of the bearings.  The outboard seal ring is clamped between the end cap and the outboard cone, whereas the inboard seal ring is clamped between the inboard cone and the backing ring.  A slight clearance exists between the inboard seal ring and the journal to prevent fretting beneath that sea ring due to slight flexures in the journal.  The inboard seal ring fits into a bore on the fillet ring so the fillet ring maintains the inboard seal ring centered with respect to the axis of rotation.

Title: Compact molded case circuit breaker with increased ampere rating
Inventor: MORGAN ROGER J
IPC: H01H9/00
Filed: 1991-05-09
Abstract: A compact molded case circuit breaker with increased ampere rating employs a latch assembly for maintaining the circuit breaker operating mechanism in a closed condition against a pair of powerful operating springs.

Inventor: GUTENSON CHARLES E
IPC: H02G3/00
Filed: 1991-01-16
Abstract: A wiring layout for new home construction is disclosed in which primarily two different cables conduct distribute various electrical signals from a central location to different rooms in a home.  The first cable, an AC power and internal communications cable, is a ribbon cable containing power conductors and digital data conductors. A predetermined number of lengths of this ribbon cable form that number of branches from the central location to different areas of the home. The second cable, the external communications cable, is a cable containing coaxial conductors and twisted wire pairs in one casing. This cable is run from the central location to a splitter. A predetermined number of lengths of the second cable are then run from the splitter to selected locations in some or all the rooms. The resulting layout from this combination branch-star layout allows efficient transmission of signals through a home and enables reduced installation costs.

Abstract: A capacitor (58) is charged to a high potential or voltage from a power source (52).  A plasma switch,  (56) preferably a CROSSATRON modulator switch, is periodically closed and opened to discharge the capacitor (58) into an object (12) for implantation with ions from a plasma (19) in a plasma source ion implantation apparatus (10).  The periodic discharge results  in the application of high voltage negative pulses to the object (12), causing ions from the plasma (19) to be accelerated toward, and implant-ed into the object (12).   A pulse transformer  (92)  is preferably provided between the plasma switch  (56)  and capacitor (58), and the object (12) to step up the voltage of the pulses and enable the plasma switch (56) to operate at lower voltage levels.  The plasma switch (56) enables high duty factor and power operation, and may be combined with arc  detection  and  suppression  circuitry  (64)  to prevent arcing between the object (12) and plasma (19).  A second power source (52), capacitor (58), and plasma switch (56) may be provided to apply positive pulses to the object (12) in alternation with the negative pulses to cause generation of the plasma, or to accelerate electrons into the object  (12)  for performing thermally assisted  ion implantation, surface annealing, and the like.

Title: Triple lock handcuff with cushion grip
Inventor: CORCORAN DAN E
IPC: E05B75/00
Filed: 1992-05-22
Abstract: A triple-lock handcuff of the type having a blade pivotally joined to spaced-apart cheek plates for movement through a locking channel includes several improvements. The lock assembly includes first and second pawl members resiliently urged toward the channel independently of one another by separate springs. A key operated extractor block carries a yoke for moving both pawl members simultaneously away from the channel to open the handcuff. The first and second pawl members are spaced-apart within the locking channel. An elongate resilient cushion is arranged along the inner edge of the blade so as to assume a first unloaded profile capable of passing between the cheek plates and, alternately, a second profile when bearing upon a limb, incapable of passing between the cheek plates. A sleeve detachably fastens the cushion to the blade's inner edge while leaving the blade's outer edge free of overlay. When the cushion is loaded, the sleeve locks the cushion on the edge of the blade by urging a pair of opposed feet into grooves formed in the side of the blade.

Patent CA-2083863-A1 (CA)
Inventor: HAAS THOMAS
IPC: C07B61/00
Filed: 1992-11-26
Abstract: This invention relates to a process for the preparation of 3-hydroxyalkanals  having 3 to 12, in particular 3 or 4 carbon atoms, by hydration of the corresponding 2-alkenals with water in a homogeneous phase in the presence of an acid catalyst.  The previously known hydration using mineral acids or carboxylic acids as catalyst results in low volume/time yields and/or low selectivities.  These disadvantages can be avoided by using, as catalyst, a dissolved acid-base buffer which results in a pH of from 2 to 5 in the reaction mixture and the acid component and corresponding base of which are present in a total quantity of from 0.5 to 40% by weight in the reaction mixture.  The preferred buffers composed of a low monobasic carboxylic acid and a tertiary amine can easily be recycled.
