Patent CA-1243798-A (CA)
Title: Polymer composition
Inventor: COX MICHAEL K
IPC: C08K3/38
Filed: 1985-01-31
Granted: 1988-10-25
Abstract: Abstract Polymer Composition A polyaryletherketone composition has a pliability which is such that a wire coated with the composition has a recoil of not more than 40°.  Compositions having such pliability include those containing a polyaryletherketone and boron nitride.  The polyaryletherketone can be polyaryletheretherketone.  The composition can be obtained by blending together the polymer and boron nitride, and the blend can be extruded onto an electrical conductor.  When extruded onto a wire, the composition gives a more pliable coated wire than is obtained using the polymer alone as the wire coating. The composition gives a coherent coating when coated onto a wire. The composition is also suitable for the production of bearings or bearing liners.

Abstract: ABSTRACT OF THE INVENTION        "A SEMICONDUCTOR POWER SWITCH COMPRISING A THYRISTOR"     A power switch comprises an asymmetrically blocking thyristor (ASCR) (1) which is connected in series with a diode (2).  Both the ASCR and the diode require only approximately half the central zone thickness as compared with a symmetrically blocking thyristor designed for an equal blocking voltage in the reverse direction (URRM).  This results in a substantially smaller turn-off delay charge (Qrr) for the series arrangement.     (Figure 1)

Abstract: Abstract of the Disclosure There is disclosed a diazotype copier for deodorizing developed diazocopy material.  The copier includes a light source for exposing the diazotype copy material and a developing chamber for developing the exposed copy material.          After exiting the developing chamber, the developed material passes under a heating chamber which includes a heating element and means for providing a flow of air into the chamber, around the heating element, and across the developed copy material.          The heated air releases the entrapped ammonia vapors from the developed copy material.  Thereafter, the air, including the released ammonia vapors, flows toward and into a scavenging device which neutralizes the ammonia vapors.

Abstract: ABSTRACT         The specification discloses a coin mechanism for dis-pensing machines including two or more  rectangular chutes  for receiving and containing a given number of coins.  A rectangular gate selectively directs coins into the chutes and a rocker arm is operable to pivot the gate from a first position and hold it in a second position to direct coins into a second chute when the coins reach a predetermined height in a first chute.   A pawl is adjustably mounted adjacent to the second chute and is operable to prevent upward movement of  a predetermined number of coins deposited  in  the  second  chute.   A  catch  plate  is  pivotally attached to the door of the dispensing machine and is located below the chutes to support the coins therein.   The catch plate receives a hook which prevents opening of  the door until  the coins  in the second chute  are high  enough  to engage the pawl whereupon  the  lower  coin  in  the  second  chute  engages  a  cam located on the catch plate causing the plate to pivot downward as the door  is opened  thereby escaping the hook and allowing the coins to fall out of the chutes.  A number of intermediate chutes may be located between the first and second chutes.  A contact lever located in an intermediate chute is operable to engage the rocker arm and pivot the gate to a next position directing coins into the next chute when the coins  in the  intermediate chute reach a predetermined height.

Abstract: A B S T R A C T     This invention consists of a tractor drawn planter which automatically plants equally spaced, especially prepared transplants into the ground.  It is made of a rectangular frame-work having two rear wheels upon which it rides and a flexible hitch to attach it to the tractor.  A magazine and a discharge tube contains the transplant.  Inside, the discharge tubes are provided with doors which allow the passage of the transplant through one tube at a time.  These doors are controlled by a computer controlled motor powered by the tractor battery which in turn moves a positioner by a rotating threaded rod to force open the spring loaded doors to allow passage of transplants through one tube at a time.  A travelling flat belt transports the transplant to the rear of the transplanter where a door controlled by a spring loaded solenoid controlled by a computer powered by the tractor battery, drops the transplant through the positioner and into the planting furrow.  A plow opens the ground to provide an opening for the transplant to enter.

Abstract: ABSTRACT OF THE DISCLOSURE           A helical scan type video tape recorder (VTR) having an editing function mode in which a new video signal can be inserted between a cut-in point and cut-out point on a previously recorded video tape.  The VTR comprises a rotary head drum; a rotary video head secured to the rotary head drum for recording video signals on the video tape in a plurality of skewed video tracks; a recording control circuit for supplying a recording current of the new video signal to the video head in response to a recording command signal; a rotary erase head secured to the rotary head drum for erasing a video signal recorded on selected ones of the video tracks, the rotary erase head being positioned to scan the tracks ahead of the video head by a predetermined interval; and an erasing control circuit for supplying an erasing current, in response to the recording command signal, to the rotary erase head during the editing interval of the editing function mode except for at least one or two intervals in which the rotary erase head traces tracks at the cut-in point and the cut-out point so that the erasing current does not leak to the adjacent track in advance of the cut-in point and to the adjacent track following the cut-out point.  Consequently, a fringe effect caused by the operation of the erase head is prevented from affecting other tracks outside the cut-in and cut-out point tracks.
