Patent CA-2053071-A1 (CA)
Inventor: PLUMMER DAVID D
IPC: E06B3/972
Filed: 1991-10-09
Abstract: A corner fastener (10) is used for securing a first frame member  (11)  to a second frame member  (12).   The corner fastener (10)  includes a body sized to be inserted in a cavity (11c)of the first frame member (11).  Locking tabs (22 and 32) have first ends (22a and 32a) operatively connected to the body and second ends  (22b and 32b)  free to move between an unengaged position and an engaged position.  The locking means have detent engaging members (24 and 34). The body has a fastening member aperture (27a and 37a).   The aperture is in general axial alignment with an opening (12k), wherein when the body is positioned in the cavity and when a fastening member (50) is inserted in the opening and the aperture, the detent engaging member is locked in a detent by the fastening member, thereby fastening the first and second frame members together.

Abstract: ABSTRACT OF THE DISCLOSURE      ZERO OPTICAL PARALLAX STYLUS INTERFACE DEVICE      An  improved  handwriting  capture  tablet  has  zero optical parallax allowing a highly accurate stylus driven computer-user interaction.  The plane of contact of the stylus and the plane of the writing image are made to coincide, eliminating all optical parallax and resulting registration errors.  This is accomplished by the use of an image transmission device, such as a fiber-optic face plate,  to transmit the  generated image to the stylus plane of contact.

Patent CA-2066599-A1 (CA)
Inventor: SMYTH PETER P
IPC: H04B10/69
Filed: 1990-09-13
Abstract: An optical detector for use in detecting digital optical signals has an optical fibre coupler (2) which splits a received optical signal into two signal portions. The coupler (2) has unequal length output fibres (8, 10) so that one signal portion impinges an as-sociated photodetector (12, 14) delayed relative to the other. The photodetectors (12, 14) are connected in series non opposed. When the delay is equal to the bit period of the optical signal the output of the detector is the differential code (dicode) of the re-ceived signal which can be recovered by a high input impedance, i.e integrating, amplifier. By forming the dicode in the optical domain in this manner large DC and AC dynamic ranges are obtained without linearity constraints on the optical transmission source that apply when the optical signal is transmitted as a dicode.

Title: Method for recovery of a computer program infected by a computer virus
Inventor: MANN OMRI
IPC: G06F21/00
Filed: 1992-05-22
Abstract: A recovery technique allows a computer program to be recovered from a program which has been infected with a computer virus. Prior to the program being infected, a unique fingerprint of the program is taken and stored along with data relating to the beginning portion of the program at a location separate from the program. A program thought to be infected is processed by generating a fingerprint of a string in the program utilizing the stored data. The fingerprint that is generated is compared with the stored fingerprint to determine whether or not the two fingerprints match. If the fingerprints match, the program is restored from the stored information and the string. If the fingerprints do not match, the value utilized to select the string can be incremented and the process repeated.

IPC: G06F7/72
Filed: 1990-12-25
Abstract: ABSTRACT        A high speed operation system intended for data closed for operations such as floating-point data in which a desired final operational result is obtained by converting the data to the one for which an arithmetic and logict ( ALU ) can be simplified (the number of elements and gate delay time, etc., are reduced ) with an encoder .PHI., by executing a series of operations for the encoded data, and by restoring the obtained result to the original data representation with a decoder,  ?.  The encoding is defined by mappings which correspond completely to the respective ones of the ALU for the original data representation(the ALU for the original operation system), the encoder .PHI., the decoder ?, and the ALU for the encoded data (the ALU for the new operation system).  Therefore, the encording such that the ALU of the ALU of the new operation system can be simplified can be determined by, for example, utilizing a computer.

Abstract: A brushwood clearing machine comprises two mutually adjacent brushwood cutting units rotating in opposite directions about respective parallel axes lying in a generally horizontal plane.  The cutting units are elongate and comprise cylindrical surfaces centered on the axes of rotation, and longitudinal brushwood cutting blades mounted on the cylindrical surfaces.   In the region between the cylindrical surfaces of the two cutting units, the cutting blades of one cutting unit imbricate the cutting blades of the other cutting unit.  In operation, rotation of the cutting  units  in  opposite  directions  force  the brushwood between the cylindrical surfaces where the blades cut the brushwood and throw the cut brushwood material upwardly.  A funnel-like channel has a wide lower  opening  surrounding  the  cutting  units  to efficiently  receive  the  cut  brushwood  material directed toward a discharge opening of this channel. The latter opening can be provided with a spout to discharge the cut brushwood material into a container.

Title: Method for evacuating floating sludge from settling tanks and thickener tanks
Inventor: KETTENBACH KARL
IPC: B01D21/24
Filed: 1992-09-03
Abstract: Abstract The  new  floating  sludge  evacuating  unit  for circular tanks having a drain,  and a  scraper blade movable in relation thereto is characterized in that the  scraper blade is  lifted repeatedly in  order  to evacuate the tank surface by sections, advanced to a position remote from the drain where it is stopped and lowered, while the drain follows the scraper blade and pushes the floating sludge together, and that prior to the lowering motion causing the floating sludge to be evacuated a push-down unit causes the intake edge of the drain to be pre-lowered to a position which takes the level in the tank into account. Then, the lowering path  for  floating  sludge  evacuation  will  always  be correct,  and evacuation of water will be avoided.  A scraper  blade  interacting  with  several  stationary drains is operating according to the same principle. It is lowered behind every drain and pushes the floating sludge toward the next drain.

Patent CA-2083227-A1 (CA)
Inventor: CHASE RUSSELL C
IPC: B25B1/24
Filed: 1992-11-18
Abstract: A machine tool vice is provided with a set of soft jaws. The soft jaws attach inside and against two master jaws.  Both jaws of the vice are equipped with an alignment mechanism to position the soft jaws to assure repositioning.  Each jaw is provided with a lengthwise slot which provides a registration face at right angles to an upright registration face at the master jaw.  The soft jaw is provided with a bracket that  registers  on   the two faces just mentioned to obtain  precise  repositioning in two  dimensions. Positioning in the third dimension is accomplished by use of a registration pin joining the soft jaw to the master jaw, and a tapered set screw threading into a chamfered opening is used along with the pin to accomplish clamping, thereby assuring complete registration of the bracket holding the soft jaw  in the vice.  The soft jaws can be mounted, removed and later returned with assurances that the soft jaws are held at a fixed location with respect to the cutter and spindle supporting the cutter.  This overcomes errors in and assures parallelism between the cutter and the work piece ultimately supported in the soft jaws.
