Title: Atm communications equipment
Inventor: RIEDEL MICHAEL
IPC: H04L49/111
Filed: 1996-06-07
Abstract: The ATM communications equipment unit comprises at its terminals input-side and output-side multiplex equipment units designed for a statistical multiplexing of message cells. Input queues, which can be individually allocated to the output-side multiplex equipment unit, are controlled in the input-side multiplex equipment unit for storing message cells to be transmitted. In addition, indications concerning the current usage of the bandwidth available at the respective terminal are respectively retained in these input-side and output-side multiplex equipment units. For the transmission of message cells from an input-side multiplex equipment unit to an allocated output-side multiplex equipment unit, a flow control is carried out such that a request message is respectively transmitted by the input-side multiplex equipment to the output-side multiplex equipment unit for a request of a determined bandwidth. If no free bandwidth is currently available at the output side, the individual request messages are inserted into a request queue that is processed as bandwidth becomes free. As bandwidth becomes free, a determined bandwidth is offered to the respective input-side multiplex equipment unit by means of an offer message. This offer message is acknowledged with an indication of the actually required bandwidth.

Title: Inactivation of viruses present in blood components using chemically-activated compounds
Inventor: ZEPP CHARLES
IPC: C07F9/655
Filed: 1995-01-09
Abstract: A method of inactivating viral molecules present within a blood sample and compounds for use in same. The method involves adding to a virus-containing blood sample an effective quantity of a compound which both has an affinity for viral nucleic acid and which is activatable to an excited state in which the compound covalently binds viral nucleic acid. After permitting the compound to complex with viral nucleic acid, the compound is raised to its excited state by chemical activation. In a first preferred embodiment, psoralen, hypericin or a derivative of psoralen or hypericin is used as the activatable, viral-inactivating compound, and chemical activation of the compound is effected by the decomposition of a dioxetane proximate to the nucleic acid/compound complex. In a second preferred embodiment, the activatable, viral-inactivating compound is incorporated into a dioxetane molecule, and chemical activation of the compound is effected by decomposition of the dioxetane into a pair of carbonyl compounds.

Title: Electronic Controller for Linear Cryogenic Coolers
Inventor: NELSON ARTHUR RANDALL
IPC: F41G3/00
Filed: 1996-09-24
Abstract: A highly efficient motor driver circuit of an electronic controller for linear cryogenic coolers operates directly from a variable power supply, such as a batter, without the need for the voltage regulator control circuit of the prior art.      Elimination of the prior art voltage regulator ensures a higher efficiency motor driver circuit of the electronic controller. Both open-loop and closed-loop controllers electronically control the motor driver circuit. The open-loop controller protects against temperature sensor failure, and will limit maximum motor power as a function of system ambient temperature. The closed-loop controller regulates the temperature of the cold finger accurately to a preset value, using feedback from a temperature sensor along with a novel pulse-width modulation concept for modifying motor drive waveforms. The motor driver circuit provides the advantages of increased efficiency, operation from a variable power source, tight control of temperature regulation, a fail-safe mode of temperature sensor feedback, and a small envelope space enabling electronic controller mounting internal to the cooler motor/compressor assembly of a linear cryogenic cooler.

Inventor: HOY TREVOR
IPC: A63C13/00
Filed: 1997-01-31
Abstract: It is common knowledge that most conventional snow-shoes are quite cumbersome in close quarters because of their length and width ( i.e. 44" x 13" wide ) .This invention ,overcoming a great deal of this difficulty by shortening the length and width ( i.é.18" x 9 3/4 ") is designed so that the feet are located close to the leading edge of the boot extension (approx.1 1/2") allowing the wearer to do many chores almost normally which may be very difficult to do while wearing conventional snow-shoes.   The harness included in this invention in combination with the flexibility of the boot extension decreases the difficulties associated with travelling and working in deep snow.

Title: Cartridge Heater System
Inventor: LACOMBE THOMAS DAVID
IPC: F24H9/18
Filed: 1995-06-15
Abstract: A linear cartridge heater has a cylindrical heater element and an integral, concentrically-mounted current collector element positioned within a fire retardant chlorinated PVC enclosure. The enclosure includes a unitarily-molded mounting flange for sealingly mounting the cartridge heater, a unitarily-molded special "tee" section interconnected with the mounting flange, and an alignment bushing. The alignment bushing is interconnected with the special "tee" section by a pipe section to form a fluid flow path between the alignment bushing and the special "tee" section. The special "tee" section provides an outlet for discharging heated water and a mounting place for a first thermistor temperature sensor. The alignment bushing mounts a second thermistor sensor and concentrically positions the heater element within the enclosure, such that the water flow rate past the heater element is substantially increased by the change from circular pipe flow into the alignment bushing to annular flow about the heater element.

Patent CA-2207217-A1 (CA)
Inventor: BARANEK BODO
IPC: F16C17/22
Filed: 1995-12-08
Abstract: A device is proposed for centering a bearing bushing on a shaft wherein the bushing is made of a material, such as a ceramic, that is sensitive to tensile stress. At lower operating temperatures the bushing exhibits a degree of play relative to the shaft, but is play-free relative thereto at high operational temperatures. Correct centering of the bushing is ensured even in the higher temperature range by the provision of a pair of centering rings which are connected to the shaft without play and act on the bushing to center it. The centering rings are made of a material which, in comparison to the bushing, is not sensitive to tensile stress. It is expedient to provide the two centering rings at the end faces of the bushing.      The clamping action of the centering rings on the bushing assures rotational pull of the bushing at low operating temperatures. The thermal expansion of the bushing and its associated clamping members approximately equals that of the corresponding shaft section to provide a butting driving connection between the shaft and the bushing at the higher operating temperature range.

Title: Point-to-multipoint broadband services drop with multiple time slot return channel for customer premises equipment
Inventor: SHARPE RANDALL B
IPC: H04N7/173
Filed: 1996-02-06
Abstract: Remote sites in a communication system are coupled over an unshielded twisted pair-configured, multi-drop communication link to an optical network unit, which is ported to the fiber optic link. In order to convey broadband information signals that have been downlinked from a master site (10) to the optical network to the remote sites, and to provide for return messages from the remote sites, a point-to-multipoint communication scheme is provided. Pursuant to this scheme, an upstream transceiver in the optical interface unit transmits STS-1 frames, which contain broadband information signals, intended for one or more remote sites, and a return time slot-representative control code associated with each destination remote site, over the multi-drop communication to the remote sites. At a remote site, a downstream transceiver uses the return time slot-representative control code to control its time of transmission over an uplink slotted bus return channel.
