Patent CA-2164785-A1 (CA)
Title: Oxide remover
Inventor: ROELLIN ERICH
IPC: B22D17/10
Filed: 1995-12-08
Abstract: Process for manufacturing shaped parts out of thixotropic metal billets in horizontal pressure diecasting machines such that inclusions of oxide skin surrounding the thixotropic metal billet are avoided in the alloy structure of the shaped part. Before introducing the thixtropic metal alloy into the space inside the mould, the oxide skin surrounding the metal billet is removed completely and collected in a container such that removal of oxide-free, homogeneous thixotropic metal alloy is minimised by taking into account the thermal and mechanical properties of the thixotropic billet, which are asymmetric with respect to the longitudinal axis of the metal billet.   The removal of the oxide skin takes place in a horizontal diecasting machine which contains an oxide remover (30) between the casting chamber (10) and the mould (70). The oxide remover (30) is represented by a ring-shaped body with a horizontal concentric middle axis (m) and a throughput opening. The oxide remover (30) contains a ring-shaped recess, the oxide deposit ring (40) which is connected to the throughput opening (31) of the oxide remover (30) via a concentric, ring-shaped oxide remover opening (42), the cross-section of the oxide remover opening (42) being asymmetric with respect to the concentric middle axis (m) of the oxide remover (30).

Title: Convertible seating arrangement
Inventor: RAUTENBACH MARTHINUS WESSEL
IPC: B60N2/34
Filed: 1996-02-08
Abstract: A convertible seating arrangement can be configured either as a seat or as a bed. The arrangement comprises a frame which supports a seat member on a track, and a back member on a pair of pivoting arms. The seat member can slide fore and aft on the track, while the back member can rotate through 180 on the arms and be locked in position thereon. With the seat member extended forwardly and the arms oriented upright, the arrangement functions as a conventional seat. The seat member can be retracted, and the back member is rotated through 180 on the arms and locked into its new position before being lowered to lie adjacent to and coplanar with the seat member to define a bed. A pair of the seating arrangements can be located facing one another and spaced apart to define a relatively large sleeping surface.

Patent CA-2177869-A1 (CA)
Inventor: KIRBY IAN JOHN
IPC: C06B21/00
Filed: 1996-05-31
Abstract: The invention provides an improved process for the production of a pyrotechnic or explosive device containing encased hazardous solid material wherein the material is dispersed in an inert liquid, the dispersion is formed into droplets and the droplets are solidified in a cooling medium.  The solidified droplets are loaded into a casing and freeze-dried in situ in the casing to produce dry particles of the hazardous material, which may optionally be pressed within the casing, advantageously under vacuum.            Only the operations (if any) subsequent to the freeze-drying need special precautions to be taken to prevent damage to personnel or equipment.            The invention is advantageous for the preparation of detonators, igniters and other devices containing hazardous materials for example lead azide, lead styphnate, pentaerythritol tetranitrate and boron/potassium nitrate mixtures.

Abstract: A microporous film of high molecular weight polyolefin useful in the prepration of filter mediums or non-aqueous battery separators and a process for producing the film are disclosed. The microporous film of high molecular weight polyolefin contains leaf vein-like fibrils as a main constituent on each of which fibrils indeterminate-form crystallites of not more than 1 µm in size flocculate and has an intrinsic viscosity, [?], of 4 dl/g or more and, preferably, has: (a) a void content of 25 % or more; (b) a gas permeability of 1900 sec/100 cc or less; (c) a tensile strength of 0.05 GPa or more; and (d) a gas impermeability-acquiring temperature of 140°C or lower. The microporous film is produced by subjecting a high molecular weight, biaxially oriented polyolefin film of 60 % or more in crystallinity to a heat treatment and, if necessary, to a stretch treatment to thereby melt or dissolve the indeterminate-form portion of the film, then crystallizing it onto the fibrils as crystallites.

IPC: H04B10/075
Filed: 1996-08-01
Abstract: There is provided a method and apparatus for managing the buffer memory of a fibre channel switch to provide a memory management system that is responsible for coupling incoming and outgoing data frames or packets to internal switch data paths. The fibre channel switch has ports that support the transmission of frames between a first and second device coupled to the ports. A number of buffer memories at each port are employed for temporarily storing frames received from the first device prior to routing by the fibre channels switch to a destination port and the associated second device. A number of state machines each corresponding to a selected buffer memory maintain buffer status information representative of whether the buffer memory is available to receive a frame. The buffer status information is analyzed by status/control logic which directs a received frame to the first of the buffer memories at the first receiving port that becomes available and updates the state machine corresponding to the first available buffer.

Title: Rolled web dispenser and cutting apparatus
Inventor: BLOCH NATHAN D
IPC: B65H19/10
Filed: 1995-03-01
Abstract: A rolled paper towel dispenser having a spring (178) loaded cutting blade gearedto rotate in conjunction with a slotted drive drum (54). The blade is shielded by a fixed cowl (34). Guide rollers (68, 70) and the drive drum include threading clips. A brake mechanism ensures that the rolled towel cannot be free spooled. Supports (25, 26, 86) are provided for both a primary roll and a stub roll. Geared sensor arms sense the diameter of the stub roll and when the diameter decreases to a point near the end of the roll, the tail from the primary roll is automatically delivered to the surface of the drive drum and automatically threaded therethrough. To dispense a towel fromthe dispenser, the user grasps the tail of the towel extending from the dispenser and pulls downward. This drives the drive drum which in turn rotates the cutting blade into position severing the sheet at the proper location.

Patent CA-2191162-A1 (CA)
Inventor: CRONK ARTHUR EDWARD
IPC: H03K17/56
Filed: 1996-11-25
Abstract: This circuit provides for a capacitor to be charged to a working level while a small current is allowed to flow through a transistor-resistor circuit which is paralleled with the gate circuitry of a thyristor. Under quiescent operating conditions when the gate circuitry is not energized, only a small current flows in the transistor-resistor circuit. Upon receipt of a turn on signal from the trigger circuit, the gate circuitry is switched on allowing the capacitor to discharge through the gate circuitry into the gate of the load thyristor.      A second transistor connected into the transistor-resistor circuit allows the initial steep pulse to be transmitted to the gate, but the gate current is limited as the second transistor biases the first transistor into a state where only a limited current may pass to the thyristor gate.

Abstract: A process is disclosed for determining the position and/or the displacement in time (trace) of a (radar) target surface by means of a radar installation. A  predeterminable number M of the largest echo amplitudes is first determined for the target surface, as well as the corresponding resolution cells (distance and azimuth co-ordinates). By averaging the distance and azimuth co-ordinates of the selected resolution cells, co-ordinates are determined for a reference point that is stable in space in relation to the target surface.  This reference point is used for locating and/or tracing objects, in particular ships.
