Patent CA-2009717-A1 (CA)
IPC: G06F12/10
Filed: 1990-02-09
Abstract: ABSTRACT OF THE DISCLOSURE     A multiprocessing system comprises a single translation lookaside buffer partitioned into a plurality of buffer areas, and a plurality of directory registers respectively corresponding to the buffer areas. Each register is partitioned into a first field and a second field having bit positions respectively assigned to processors. A directory controller selects one of the registers and writes a segmented virtual space identifier of a requesting processor into the first field of the selected register and a bit "1" into its second field in a position assigned to the requesting processor. If, during a nonshared-access mode, the directory controller accesses a buffer area corresponding to the selected register to load a copy of the translation tables from a main memory into the buffer area.          During a shared-access mode, the directory controller searches all registers to detect a first one whose first field contains the segmented virtual space identifier of the requesting processor and whose second field contains a bit "1" in a position assigned to that processor and a second register whose first field contains the same identifier as the first and whose second field contains a bit "1" in a position assigned to a master processor to indicate the denial of access right. The bit "1" of the first register is reset to zero and a bit "1" is set in the second field of the second register in a position assigned to the requesting processor to indicate the grant of access right. In a subsequent, nonshared-access mode, one of the bits "1" in the second register is reset in a position assigned to the requesting processor and a copy of the translation tables is loaded into the buffer area corresponding to the register containing instructions issued from the requesting processor.

Title: Method and apparatus for maintaining an opening in outdoor ice
Inventor: SCHEFERS HERBERT F
IPC: A01K97/01
Filed: 1990-03-19
Abstract: 89,0105 H.F. & S. O. SCHEFERS      ABSTRACT OF THE DISCLOSURE       A method and apparatus using a pressurizable bladder for maintaining a hole open in outdoor ice atop a body of water.  The apparatus has a top plug with an air tube and valve, an elongate bladder extending down from the plug, and radially spaced apart longitudinal cords in the bladder which constrains elongate growth but enable diameter growth of the bladder.  The method has steps of placing the ice plug over a hole, weighing the ice plug, inflating the bladder to a pressure of about 2-3 PSIG, and restraining the ice plug in the hole with a diametrically expanded lower part of the bladder underneath the ice.

Inventor: FAESSLER COURT
IPC: E05B65/00
Filed: 1990-09-07
Abstract: A cable lock assembly for the bundling of lengths of material such as logs includes a lock affixed to a first end of a cable. One of a number of buttons rigidly affixed to the cable at a second end thereof may be placed in a complementarily shaped socket in a base of the lock. The button may be retained in the socket by a cover which is rotatably connected to the base and may be releasably secured thereto in its button retaining closed position. The cable lock assembly of the present invention is easy to handle without the requirement of specific tools and is reusable, thus reducing operating costs. Slipping of the cable through the lock in the closed position of the cover is substantially prevented, thus improving the reliability of the cable lock assembly.

Abstract: A  lift-off  shoe system uses non-locking sash support shoes (30) movable vertically and  spring  biased upwardly  in  a  tilt window.  Sash pins (25) have heads (26) that interlock with open top slots  (31)  in  sash shoes  (30)  so that the sash pins are removable from the shoes only by lifting the pins vertically from above  the uppermost  position  of  the shoes.  This simplifies the shoes,  eliminates  damage  caused  by   shoe-locking mechanisms,  and makes sash removal and replacement simple and convenient.

IPC: G02B7/00
Filed: 1990-10-01
Abstract: In a device for injecting the light energy of a laser beam into a multimode fibre-optic optical waveguide (2) a small part of the light emerging from the end face of the optical waveguide (2) is projected through a beam splitting cube (7) and a reproducing lens (21) onto a display screen (1), so that an image (24) of the end face of the optical waveguide (2) can be observed on the display screen (1). The arrangement is such that the system is correctly focused only when the distance between the optical waveguide (2) and a focusing point of the laser beam (12) reaches an intended value. The light spot of the laser beam on the end face of the optical waveguide (2) is clearly visible on the display screen (1) so that an optimum positioning and adjustment can be readily effected.

Patent CA-2028291-A1 (CA)
IPC: E05D3/06
Filed: 1990-10-23
Abstract: ABSTRACT OF THE DISCLOSURE A multiple piece thrust bearing assembly for a hinge structure having two hinge members and a clamp member.  The hinge members are rotatably joined along their adjacent longitudinally extending edges by intermeshing gear segments which are held together by the clamp member to permit smooth and uniform movement of the hinge members.  The multi-piece thrust bearing assembly of the present invention comprises a thrust bearing member and bearing inserts arranged between the thrust bearing member and each of the hinge members for improving durability of the thrust bearing assembly and, thereby, the hinge structure.  The thrust bearing member of the bearing assembly is formed from a non-metallic material which extends laterally across the hinge members to inhibit their longitudinal movement relative to each other.  A first or upper pair of non-metallic bearing inserts are arranged between an upper bearing surface of the thrust bearing member and each of the hinge members to reduce frictional sliding contact therebetween.  A second or lower pair of non-metallic bearing inserts are arranged between a lower bearing surface of the thrust bearing and each of the hinge members to further reduce frictional sliding contact therebetween.

Abstract: An animal gate latch mechanism having upper and lower latch units movable successively and alternatively between gate open and  gate  latching  positions  therefor  by  a  linkage  system including a single actuating arm.  From a gate open position of both latch units, movement of the actuating arm in one direction will independently move the latch units  to the gate latching positions therefor.   An intermediate latched condition of the gate is thus provided which can quickly and easily be effected by an operator on horseback.  With both latch units in the latched position  therefor,  the  gate  is  securely  latched  at  two spaced-apart  locations  to prevent  twisting of  the  gate by a confined animal and its possible escape therethrough.

Title: Centerless runout and profile inspection system and method
Inventor: MILLER THOMAS W
IPC: G01B21/00
Filed: 1991-07-19
Abstract: Abstract of the Disclosure The runout or profile of parts is measured without the  need  for  precision  supports  by  rotating  the  part generally  about  an  axis  of  rotation.    The  changes  in position of one or more reference surfaces on the part along first and second  tracking axes are measured for a plurality of rotational positions of the part.  The change in position of the target surface for which the runout or profile is to be determined is measured along a third tracking axis which lies substantially in a common plane with the first and second  tracking  axes.    The  change  in  position  of  the rotational axis of the part along the third tracking axis is determined from the changes in position of the one or more reference surfaces and the distances between the tracking axes, and is subtracted from the measured change in position of  the  target  surface along  the  third  tracking axis  to determine the runout or profile.   Independent measurement devices, which can be aligned to the vertical using a level when the tracking axes are horizontal comprise a transmitter generating  a  plane  of  laser  energy  extending  along  and perpendicular  to the  tracking  axis and a  receiver  which detects the change in the portion of  the plane of laser energy blocked by the surface being tracked.
