Patent CA-2094990-C (CA)
Inventor: DADEL MARTIN ROBERT
IPC: B60T10/02

Granted: 1997-02-25
Abstract: An electronically controlled hydrodynamic retarder interconnects with the output shaft of a vehicle transmission to selectively apply a braking torque thereto. The retarder includes a solenoid valve, the operating duty cycle of which controls the retarder capacity and resultant braking torque. A control unit, interconnecting the transmission and the retarder, regulates the duty cycle of the solenoid valve to regulate the retarder operation as a function of excessive deceleration or overheating, while also regulating such operation during downshift to assure efficient, effective, and comfortable operation of the transmission/retarder. The retarder is adaptive to accommodate variations resulting from age, wear, and the like.

Abstract: This device is used for controlling the attitude of a spacecraft to be rotated about a body axis of rotation.      Actuators 38 generate torques about the axis of rotation and two lateral axes. Angular velocity signals .omega.x, .omega.y with respect to the lateral axes are in each case fed to first and second signal paths 19, 20 and 21, 22. The latter contain an integrator 25. Modulators 36 and 37, which each comprise a variable dead zone, supply control signals for the actuators 38. In order to limit the nutation amplitude in a reliable manner to a constant value, multiplication elements 23, 24 and 26, 27 are provided in the first and second signal paths, in which multiplication elements the lateral-axis angular velocity signals .omega.x, .omega.y or the angular position signals .PHI., .theta. are acted upon by factors which are proportional to the rotation axis angular velocity signal .omega.z or its square. Furthermore, the thresholds of the dead zones of the modulators 36, 37 are varied proportionally to .omega.~. A corresponding process for the attitude control is also indicated.

Abstract: Sustained release oral drug dosage forms that comprise a tablet or capsule of a plurality of particles of a solid-state drug dispersed in alkyl cellulose such as hydroxyethylcellulose or hydroxypropylcellulose. Once ingested the tablet or capsule disinte-grates to disperse the particles into the stomach where they imbibe water to cause them to swell and also to become slippery, thus enhancing their retention in the stomach. Imbibed water from the gastric fluid dissolves the drug entrapped in the particles and the resulting solution diffuses from the dispersed particles, assuring that no solid drug, which is more irritating, contacts the mu-cosal tissue. A number of embodiments of the dosage form utilizing different drugs are exemplified and the benefits are ex-plained. Aspirin is one example.

Title: Telecommunication system with synchronous-asynchronous interface
Inventor: PUNJ VIKRAM
IPC: H04L12/56
Filed: 1995-10-26
Granted: 2001-01-02
Abstract: Line cards provide an input/output interface between synchronous communication channels and an asynchronous network.          An input line card generates a plurality of packets where each packet contains information carried by a group of synchronous communication channels; each synchronous communication channel of the group having a destination of the same output line card.  A mechanism is provided for selecting a sequence for the sequential transmission of packets from the input line cards to the asynchronous network.  The selecting mechanism minimizes  the probability that a plurality of the input line cards will concurrently transmit a packet to the same output line card thereby creating a collision of packets requiring that all but one of the colliding packets be stored in a queue.  Thus, minimizing collisions also minimizes queuing delays.

Abstract: A two roll paper dispenser has an enclosure for confining first and second roll-supporting man-drels mounted on slide blocks in a cantilevered po-sition.  The mandrels are movable from a first posi-tion wherein the first mandrel slide block is lo-cated at a juncture of a first path portion and a second path portion and the second mandrel slide block is located above the first mandrel slide block in the first path portion and wherein the first man-drel slide block can be moved from the juncture along the second path portion when sufficient paper is consumed from the roll carried thereon to open the juncture allowing the slide block of the second mandrel to be moved to expose the second roll to the access opening.  A spring engages the first mandrel slide block biasing the mandrel for movement away from the juncture,  and the second mandrel slide block is biased for movement along the second path toward the juncture.  The housing is preferably pro-vided with a metering block on its rear wall posi-tioned to engage a roll of paper on the first man-drel. The block serves multiple functions, including limiting the use of the dispenser to accomodate a particular diameter roll. Movement of the roll on the second mandrel to the juncture is also prevented until the roll of paper on the first mandrel is ex-hausted.  The projection preferably has a convex roll-engaging surface.   The mandrels each have a proximal end attached to one of the mandrel slide blocks and a distal free end for insertion thereon of a roll of paper.  The distal end is tapered on its lower surface to a reduced diameter and is pro-vided on its upper surface with an upwardly extend-ing projection.
