Patent CA-2111458-A1 (CA)
Title: Method of decorticating flax, and flax-processing machine designed to carry out the method
Inventor: SCHAAL WALTER
IPC: A01D45/06
Filed: 1992-06-12
Abstract: (57) Abstract Described is a method of decorticating flax, and a ma-chine suitable for doing this. The aim of the invention is to pro-duce, after only a short dew-retting time or light chemical pre-treatment, a degree of decortication sufficient to form the preli-minary step of a constant-flow fibre-digestion process. The flax is picked up as a tangled mass and processed in a tangential-flow breaker unit(10, 11) and a subsequent longitudinal-flow fi-bre scutching and cleaning unit (12). Incorporated in the first breaker (10) is a system of parallel slots and in the second breaker (11) a peripheral gap whose axis of curvature is at right angles to the slots in the first breaker (10). The fibre scutching and cleaning unit (12) has several longitudinal sections fitted with fibre-conveying and loosening means which separate and clean the fibres. The decorticated fibres are then compressed, in a built-on baler unit (22), into bales.
Patent CA-2114329-A1 (CA)
Title: Powered rotatable curved instrument
Inventor: SMITH GRAHAM
IPC: A61B17/28
Filed: 1994-01-27
Abstract: POWERED ROTATABLE CURVED INSTRUMENT                           ABSTRACT       A surgical instrument includes a first member that has an opening in its distal region for admitting tissue and that is rotatable with respect to a base from which the first member extends to allow the rotational orientation of the opening to be selectively changed with respect to the axis of the instrument.  A second member is disposed within the first member to transmit force to move a cutting implement disposed at its distal end and cause it to cut tissue that is exposed to the implement through the opening.  In one embodiment, a curved, rigid member is disposed coaxially with the first and second members to provide the first member with a bend region that angularly offsets the distal region (and hence the opening) from the axis of the instrument in a selected direction. The first member is relatively flexible, at least in the bend region, to allow the rotational orientation of the opening to be changed without changing the selected direction of the offset.  At least a portion of the second member that is disposed in the bend region is also relatively flexible to transmit the applied force through the bend region to the cutting implement.

Title: Adjustable strobe with temperature stabilization
Inventor: APPLEGATE EDWARD V
IPC: G08B7/06
Filed: 1994-03-09
Abstract: Abstract of the Disclosure Adjustable Strobe With Temperature Stabilization A strobe alarm circuit includes a voltage source circuit which has a capacitor connected across its output terminals.  The voltage source circuit is connected to a flash circuit which includes a flashtube shunted by a trigger circuit.  The trigger circuit causes the flashtube to flash when the voltage across the voltage source circuit capacitor reaches a predetermined threshold firing voltage.  A resistor divider network is employed in the trigger circuit to ensure that the flashtube is triggered at virtually the same instant as the voltage across the capacitor exceeds the trigger threshold value.

Title: Snap-on wallplate system
Inventor: ARENAS ALFREDO
IPC: H02G3/14
Filed: 1995-01-12
Abstract: A cover plate device for covering a wall mounted wiring device having no visible fasteners when installed. An attachment device is attached over a siring device to the ears of a gang box using the screws normally employed to attach the wiring device to such gang box. Latch pawls are arranged at the opposite longitudinal ends of the attachment device. A cover plate member overlies the wiring device and gang box and provides a series of recesses to receive the associated pawls in locking arrangement. Because of the number of recesses available at each pawl location, the cover plate can still be installed even if the wall is not flat or even. The attachment member and cover plate member can be provided with various types and numbers of apertures, and the number of pawls and groups of recesses employed depend on the size of the attachment and cover plate members.

Abstract: A cooling system includes a unit for processing product to be cooled or frozen.  A secondary refrigeration loop is connected to this unit and introduces a refrigerant at or near atmospheric pressure into the unit.  The secondary refrigeration loop may be open or closed.  The secondary loop includes a secondary heat exchanger for cooling the refrigerant.  A primary, closed refrigeration loop, operating at a pressure of not less than 2 atmospheres, includes a forward flow path which comprises a primary refrigerant compressor for producing compressed primary refrigerant, a primary heat exchanger for receiving and cooling the compressed primary refrigerant and an expander for further cooling and transferring the compressed refrigerant to the secondary heat exchanger to enable cooling of the secondary refrigerant.  The primary loop further includes a return flow path from the secondary heat exchanger to the primary refrigerant compressor and to the primary heat exchanger.  The primary heat exchanger thereby provides heat exchange from the return flow path to the forward flow path to accomplish a cooling action.
