Title: Media server for supplying video and multi-media data over the public telephone switched network
Inventor: CRAIG BERNARD J
IPC: H04N7/173
Filed: 1993-06-18
Abstract: A media server receives, stores and forwards multi-media data and full motion video feature presentations within a PSTN.  The media server receives wide band digital video and MPEG encoded video signals.  The wide band digital video is encoded using either a real time MPEG encoding for immediate transmission over network facilities to subscribers or using a multi-pass MPEG encoder for storage by the Media Server for subsequent transmission.   The Media Server includes DRAM, optical and magnetic disk storage, high speed tape storage and archival storage.   A Librarian Processor allocates storage space on a media appropriate to retrieval requirements for the video data.  The Librarian is responsive to a storage Manager Processor and a Session Manager Processor for providing video program data to an Output Controller.
Patent CA-2140053-A1 (CA)
Inventor: ROSENBLATT JOEL S
IPC: A61K38/00
Filed: 1995-01-11
Abstract: Drugs are delivered in a sustained manner from an in vivo depot which is formed from a collagen-based injectable composition. The injectable composition is fluid when injected but undergoes crosslinking in situ to form a crosslinked collagen matrix which encloses the drug to be released. The composition also includes a flexible chain polymer which is similarly charged to the precrosslinked collagen. This flexible chain polymer is enclosed in the matrix as well when the matrix forms and alters the effective porosity of the matrix. The drug diffuses out of the matrix at a rate which depends upon the matrix's effective porosity.

Title: Flexing Keyboard Structure for a Notebook Computer
Inventor: CLANCY KEVIN F
IPC: H01H13/70
Filed: 1995-06-28
Abstract: A notebook computer has a keyboard structure with a flexible top side portion disposed along the top side of its base housing to which the computer lid portion is secured for movement between a closed position in which the lid portion extends across and covers the top side of the base housing and the keyboard structure, and an open position in which the lid portion is generally transverse to the base housing and uncovers the keyboard structure.  The flexible top side portion of the keyboard structure is linked to the computer lid portion in a manner such that when the lid portion is closed the top side portion of the keyboard structure is essentially flat and parallel to the bottom side of the base housing, and when the lid portion is opened, the top side portion of the keyboard structure is resiliently bent to an upwardly and rearwardly sloped orientation and concavely curved in an upward direction to thereby emulate the slope, curvature and typing feel of a sculpted desktop computer keyboard.
Patent CA-2152938-A1 (CA)
Title: Glassware transfer
Inventor: BOLIN JAMES A
IPC: C03B35/10
Filed: 1993-12-28
Abstract: A pusher mechanism of a bottle forming machine transfers a plurality of glass bottles onto a belt by rotating the bottles through an arc to align the bottles with the belt (72) while moving the bottles at a converging acute angle toward the belt. The movement increase the radius of the path and the speed of the bottles. The centrifugal effect applied to the bottles by the pusher mechanism is limited or reduced without introducing instabilities in the bottles. A nozzle (290) is positioned to counteract instabilities.  A takeout mechanism rotates the bottles at an acute angle to the conveyor belt. This initial acute angle reduces the amount of rotation which the pusher mechanism must impart when placing the bottles on the conveyor, thus reducing the possibility of introducing instabilities.

Title: Spit and pan barbecue system with direct drive and canopy therefore
Inventor: DANTZER HUGH
IPC: A47J37/07
Filed: 1995-06-30
Abstract: An assemblage of metal products, dubbed a roasting pan, that enables a person to effortlessly and safely roast an entire animal carcass.  This unique roasting pan is designed to ensure success in roasting meat thoroughly while simultaneously reducing the risk of burning and undercooking meat.  This is accomplished with the following features the roasting pan provides. 1) The spit system is long enough to accommodate any carcass up to 150 lbs.  The attachments are designed to ensure the carcass will adhere to the spit and not become dislodged at any time during the roasting process. 2) The roasting pan includes crank lifters that enable a person, with minimal effort, to raise or lower the carcass as required.  This is to prevent burning or undercooking while roasting. 3) The motor is self-contained and has a fan-cooled direct drive attached to the lift system. 4) In front of the direct drive motor is a stationery cradle that helps accommodate the spit prior to installation into the motor.  The cradle is positioned in such a way that the spit, once placed in the cradle, can be engaged quickly and easily into the direct drive motor by sliding it off the cradle directly into the connector on the direct drive motor. 5) The pan opens up into a canopy-style unit.  The lid forms the back, and the inside section of the lid folds out to form the roof of the canopy.  This permits roasting under a variety of weather conditions.  Also, the canopy creates a convection effect, reducing roasting time (compared to a conventional open air roaster) by half. 6) The pan has four stationery legs with pneumatic tires.  Two of the four wheels are the swivel type with locking positions.  This enables a person to brake the pan into position to prevent rolling on uneven surfaces.

Abstract: An automatic door opening and closing system opens a door by driving means when a person approaches the door.  A monitoring area is set in the vicinity of the door, and moving speed and direction computing means computes the speed and direction of movement of the person on the basis of changes in position of the person in the monitoring area.  When it is judged from the computed direction of movement that the person is moving toward the door, door enabling area selecting means selects one of plural door enabling areas suitable for the speed of movement of the object.  Open-door command means provides an open-door signal, which causes the door to be opened at a fixed speed, to the driving means so that the door is fully opened upon the predicted arrival of the person at the door.

Patent CA-2157986-A1 (CA)
Title: Sync separator and video signal detector circuits
Inventor: BRUINS BRYAN
IPC: H04N5/16
Filed: 1995-09-11
Abstract: Sync separator and video detector circuits, including a sync tip clamp having symmetrical and non-symmetrical clamps. The symmetrical clamp clamps the input video signal to a reference voltage during composite sync pulses, so the coupling capacitor discharge current is kept small between composite sync pulses. For startup, the non-symmetrical clamp employs an operational amplifier, diode and controllable current source to charge the coupling capacitor to a minimum desired level, and to discharge the capacitor e.g. when there is a change in DC level so that the output level is too high. A sync slicing detector is also provided, using two comparators. One comparator compares the slicing level with the clamped video and produces a properly sliced composite sync output, while the other compares the clamped video with a small reference voltage and produces a fixed sync output. If the clamped video level drops suddenly, a delayed version of the fixed composite sync output clocks a flip flop, creating a fault signal which discharges a memory capacitor over a time period. When composite sync pulses are again sliced, the output from the first comparator resets the flip flop. The circuit also includes a video signal detector which enables its sync outputs only when it receives a predetermined number of valid lines of video with the frequency of the lines being in a predetermined range and with the last several lines being relatively free of noise. This is performed by a counter which provides a full count on receipt of the predetermined number of lines, but which has its inputs cleared if the frequency is outside the desired range, and which has its most significant bit cleared if significant noise is present. A timer prevents muting of the outputs if the input signal frequency is disturbed only momentarily.
