Patent CA-2143951-A1 (CA)
Inventor: PETERSEN BRIAN
IPC: H04L12/56
Filed: 1993-09-17
Abstract: Combined indication signals of data block transfers are generated by a device which reduces the number of interrupts to a host processor (5). The reduction in the number of interrupts enhances host system performance during data block transfers. An embodiment of the device may be a network adapter (3a) comprising network interface logic (11) for transferring a data frame between a network (2) and a buffer memory (9) and host interface logic (11) for transferring a data frame between a buffer memory (9) and a host system (1). The network adapter (3a) further includes threshold logic (10) for generating an early receive indication signal when a portion of the data frame is received. Indication combination logic (l0a) delays the generation of a transfer complete interrupt to slightly before the expected occurrence of the early receive indication. The host processor (5) is able to service both the transfer complete indication and the early receive indication in a single interrupt service routine caused by the transfer complete indication.

Abstract: A multi-standard video decompression apparatus has a plurality of stages interconnected by a two-wire interface arranged as a pipeline processing machine.  Control tokens and DATA Tokens pass over the single two-wire interface for carrying both control and data in token format.   A token decode circuit is positioned in certain of the stages for recognizing certain of the tokens as control tokens  pertinent  to  that  stage  and  for  passing unrecognized   control   tokens   along   the   pipeline. Reconfiguration processing circuits  are positioned  in selected stages and are responsive to a recognized control token for reconfiguring such stage to handle an identified DATA Token.  A wide variety of unique supporting subsystem circuitry and processing techniques are disclosed for implementing the system.

Title: Pipe and cable clamp with base part and receiving strap (i)
Inventor: JANSSEN RUPERT
IPC: F16L3/04
Filed: 1995-09-08
Abstract: A pipe and cable clamp is formed of a base part and a generally arcuately shaped receiving strap extending outwardly from the base part.  A joint is located in the receiving strap spaced from the free end and the joint is shaped so that the free end region extending from the joint can be folded into a receiving space bounded by the receiving strap.  As a result, pipes and cables of different diameters can be secured to the structural member, so that the free end region is folding into receiving space when smaller diameter pipes and cables are clamped, and the free end region is prevented from folding outwardly if larger diameter pipes are clamped, so that the free end region assists in securing the pipes and cable of larger diameter.

IPC: B24B33/08
Filed: 1995-11-14
Abstract: A chipping blade of the type used in the forestry industry is sharpened initially by grinding an incline surface between two parallel side surfaces of the blade so as to form a sharpened junction between the incline surface and one side surface. The grinding action generates a burr wire or bead at the junction and this is removed in a honing action in which the blade is inserted into the cusp between two rotating honing bodies and moved back and forth. The honing bodies each comprise a series of honing discs at axially spaced positions on a shaft so that the discs of one body intermesh with the discs of the other body by a distance greater than 1 inch. The discs are formed from stacked sheets of woven fabric so that the cylindrical outer surface is compressible and fibrous.

Title: Drug delivery agents incorporating mitomycin
Inventor: SCHACHT ETIENNE HONORE
IPC: A61K47/48
Filed: 1994-08-17
Abstract: A conjugate of a carrier polymer and aziridine ring containing mitomycin (MMC) drug molecules is prepared by coupling the MMC molecules via their aziridine imino groups to spacer groups that terminate in protected amino groups, deprotecting said amino groups, recovering and purifying the spacer-MMC derivatives, and then coupling these derivatives via said deprotected terminal amino groups to the carrier polymer.  Alternatively, the MMC may first be treated with an activating agent, e.g. carbodiimidazole, to form on activated MMC derivative which is then coupled directly to spacer groups linked to the carrier polymer.

Title: Liposuction apparatus
Inventor: NARAYAN KRISHNA
IPC: A61M1/00
Filed: 1994-07-29
Abstract: A method for removing adipose tissue uses an elongate rigid tube or probe member (14) hav-ing a distal end (16) and a proximal end, and an axially extending lumen (20). An incision is formed in a skin surface of a patient, the tube being inserted through the incision into subcuta-neous adipose tissues of the patient. Upon inser-tion of the tube through the incision, an ultrasonic pressure wave is generated at the proximal end of the tube, the waveform being transmitted through the tube to establish a standing wave therein. The standing ultrasonic wave in the insertion tube pro-duces cavitation bubbles at the distal end of the tube, the bubbles causing liquefaction of adipose tissues of the patient at a surgical site located dis-tally of the distal end of the insertion tube. Suc-tion is applied to the lumen of the tube, thereby aspirating the liquefied adipose tissues from the surgical site through the lumen. During the en-tire procedure, the distal end of the tube and the adipose tissues at the surgical site are maintained at approximately body temperature.          .

IPC: H04L12/56
Filed: 1996-07-16
Abstract: A method for supporting end to end VC oriented service between mobile hosts. Included are protocols designed for a micro-cellular wireless environment in which mobile hosts make frequent transitions between cells. A VC rerouting procedure minimizes the effect of frequent hand-offs by extending routes and triggering a route rebuild only when performance as seen by an application degrades below a certain level. VC establishment and rerouting protocols assume the existence of separate signaling protocols for the wired and the wireless network, respectively. This minimizes the changes required to the signaling infrastructure used in the wired network while allowing the signaling in the wireless network to be customized for the unique requirements of that particular environment.

Abstract: A noise reduction kit for modifying a two (2) spool axial flow turbofan engine with multi-stage compressors and fan driven by multi-stage reaction turbines, and a thrust of at least about 18,000 lbs. at sea level. There is a fan at the upstream end of the core engine for generating axial fan air flow through bypass ducts terminating at a common nozzle, the common nozzle having a mixing plane area for each of the fan air flow and for the exhaust gas in a range between 700 and 800 square inches. A target thrust reverser includes opposing doors rotatable into position to block and divert the flow of exhaust gas for generating reverse thrust. A material layer is located in a spacing between a tip of blades for at least some of the fans and a duct for the fans, thereby to reduce a normal clearance between the tip of blades for the fan and the duct. Mixing means for radially diverting fan air and permitting radially outward expansion of exhaust gas is provided coaxially downstream to the core engine. An acoustically dampened light bulb-shaped nose cone is provided for coaxial attachment to an upstream end of the core engine. The axial flow front fan is axially separated from the inlet guide vane is extended relatively forwardly. A bleed air valve, selectively operational to bleed air from the core engine when the valve is open, is ducted for directing bleed air to the vicinity of the common nozzle.
