Title: Hydraulic control circuits for continuously-variable-ratio transmissions
Inventor: GREENWOOD CHRISTOPHER J
IPC: F16H61/662
Filed: 1989-08-15
Granted: 1993-04-20
Abstract: ABSTRACT IMPROVEMENTS IN OR RELATING TO HYDRAULIC CONTROL CIRCUITS FOR CONTINUOUSLY-VARIABLE-RATIO TRANSMISSIONS A hydraulic control  valve for a continuously-variable-ratio transmission (CVT),  particularly one of the toroidal race rolling traction type.   The transmission includes hydraulically operated clutches  whose  capacity  to  transmit  torque  varies  with  the operating pressure supplied to them.   The transmitted ratio is related  to  the  position  of  a  hydraulic  ram   which  when  it overshoots its normal stroke creates a pressure rise upstream of it  in  the  circuit.   This  pressure  rise  first  resists  further overshoot  and then causes a reduction in the clutch operating pressure.   Ram position is controlled by valve means which are located downstream of the ram  and which are themselves sensitive to feedback from upstream circuit pressure:  when that pressure rises   the  valve  means  open  so as  to depress  the  downstream circuit  pressure  by which  the  clutches  are operated.   In  the illustrated embodiment of the invention a double-acting ram is shown  controlled by a circuit comprising two parallel hydraulic lines associated respectively with the opposite ends of the ram each  line  being  controlled  by  a  separate  downstream  control valve.   The  pressure  feedback  to  the  control  valves  and  the operating   pressure   for   the   clutches   are   taken   from cross-connections  between  the  two  lines   so  that  each  such pressure always has the higher of the values existing in the two lines at each end of the cross-connection.

Abstract: ABSTRACT OF THE DISCLOSURE        A muting  circuit which mutes noises generated instantaneously whilst turning off the power, or noises of null data generated by the data distorted by an external or internal influence.  The muting circuit in a digital audio system mutes interfering beat noises which are generated by pop noises during the process of muting. The beat noises are generated because of data distored by the pop noises during the turning off of the system power or by an external source.  A preferred embodiment includes a digital signal processor (DSP), a first latch,  a second latch,  a comparator, an address encoder, a counter,  a memory, a divider, a multiplier, and a first switching circuit.

Abstract: MODULUS CONTROL IN SILICONE SEALANT    Abstract A silicone sealant which is stable in the absence of moisture and cures upon exposure to moisture to give an elastomer with a controllable modulus is produced by mixing a polydiorganosiloxane having both vinyl and alkoxysilethylene endblocking, alkoxy silane crosslinker, titanium catalyst and optional filler.  The modulus is controlled by varying the ratio of vinyl to alkoxysilethylene endblocking present on the polymer.

Abstract: A modular joint prosthesis for implantation in a body. A component adapted to be fixed to a long bone having an intramedullary canal includes an elongated male stem having a uniformly tapered outer surface.  In order to accommodate the particular size of long bone to which the component is to be fixed, a properly sized female stem is attached to the male stem before the component is fixed to the long bone.  The female stem is adapted to be received in the intramedullary canal for fixation thereto, and has a uniformly tapered inner surface, the angle of the taper being substantially similar to the angle of taper of the outer surface of the male stem. As a result, the male stem and female stem become locked together when the inner surface of the female stem engages the outer surface of the male stem.  The proper size of female stem is obtained by selecting it from a family of female stems having a graduated sequence of different external dimensions.  Tools are also disclosed for disengaging the male stem from the female stem as well as for disengaging the female stem from the bone.

Abstract: An intraluminal grafting system includes a hollow graft which has a proximal staple positioned proximate its proximal end and a distal staple adapted proximate its distal end.  The system includes a capsule for transporting the graft through the lumen and for positioning the proximal end of the graft upstream in a lumen which may be a blood vessel or artery.  A tube is connected to the capsule and extends to exterior the vessel for manipulation by the user.  A catheter is positioned within the tube to extend from the cavity and through the graft to exterior the body.  The catheter has an inflatable membrane or balloon proximate the distal end thereof which is in communication via a channel with inflation and deflation means located exterior the vessel.  With the inflatable membrane deflated, the capsule is positioned in the lumen and manipulated to a desired location.  The inflatable membrane is manipulated by the rod away from the graft.  The force exerted by the inflatable membrane and the structure of the staples urges the staples in the vessel wall, retaining the graft in position.  The remainder of the intraluminal grafting system is then removed from the corporeal vessel.

Abstract: The disclosed invention is concerned with porous substrates impregnated with moisture curing polyurethane oligomers incorporating tertiary nitrogen atoms and free aromatic isocyanate groups in which the yellowing tendency of these isocyanates is diminished or supressed by the inclusion of specific light protection agents. These agents are either substituted oxalanilides or indole or indoline derivatives. The impregnated substrates cure rapidly when exposed to moisture to yield rigid structures suitable as a replacement for Plaster of Pairs in medicinal and veterinary bandaging applications.

Abstract: The various functional units which comprise a central pro- cessing unit of a computer are organized so as to enable a main arithmetic logic unit and special function units including an auxilliary arithmetic logic unit to access data registers, literal constants, and data from a memory cache. A general purpose bus closely couples the functional units to the main data paths and allows the CPU sequencer to branch on numerous conditions which may be indicated via test lines. Parity from the functional units is sent a clock cycle later than results in order that the parity path does not affect machine cycle time. The architecture allows unused microcode options to be used to check for correct CPU operation by halting CPU operation on a miscompare of two buses.
