Patent CA-2034363-A1 (CA)
Inventor: CHEN CHING-SHIH
IPC: G01F11/10
Filed: 1991-01-17
Abstract: ABSTRACT OF THE DISCLOSURE    In   a  cleanser  dispenser,  the   motor-operated cleanser discharge unit is provided with a plurality of press  rollers  which are mounted on a  rotary  support operated  by the motor in such a manner that  they  are angularly  spaced from one another and that their  axes are  parallel  to and equally spaced from the  axis  of rotation  of the rotary support.   The  press  rollers depress a flexible cleanser discharge conduit against a curved guide wall to stop the flow of the cleanser. The press  rollers  minimize the friction produced  on  the flexible  conduit.   The  flexible  conduit  is  always compressed by at least one press roller regardless  of the  accuracy  of the control of the  motor  operation, thereby alleviating the problem of cleanser leakage.

Title: Method for recovering and using lignin in adhesive resins
Inventor: SCHROEDER HERBERT A
IPC: C07G1/00
Filed: 1991-05-27
Abstract: ABSTRACT     Lignin, or a lignin derived material, which has been   significantly   demethylated    (e.g.,    the demethylated lignin found in the raffinate produced as a by-product of dimethyl sulfide production which can be carried out using the spent liquor from wood pulping operations)  can be isolated by a process wherein an organic solvent is added to a lignin-containing aqueous solution.  The organic solvent is typically a polar, and at least a partially water-immiscible substance such as,  for example,  ethyl acetate.   The resulting lignin-containing aqueous solution/organic  solvent  mixture  is  acidified  to produce a water layer which is discarded and an organic solvent layer which contains the demethylated lignin.  Upon its recovery, the demethylated lignin is dissolved in an alkaline solution to which an aldehyde source is added to produce a resol-type resin.  The aldehyde source may be  formaldehyde  in  solution, paraformaldehyde,  hexamethylenetetramine,  or other aldehydes including acetaldehyde, furfural, and their derivatives.

Abstract: An image rotation method and an image rotation processing apparatus in an image processing apparatus are disclosed. The image rotation method obtains the coordinates (x',y') of a second memory where the rotated image will be recorded, by sequentially scanning a first memory where the M?N original image is recorded and adding the increments of x and y corresponding to a rotation angle .theta. repeatedly, and transmits the image element data of the coordinates (x,y) of the first memory to the coordinates (x', y') of the second memory with one-to-one correspondence, thereby obtaining the rotated image through the rotation angle .theta. from the original image. Thus, the present invention can obtain the rotated image using only addition operations and without any multiplication operations, so that high-speed operation is possible and an image can be rotated through a specified angle .theta. through software in common computer graphic systems having no floating point multiplier.

Abstract: PARALLEL ASSOCIATIVE PROCESSOR SYSTEM                       ABSTRACT      Multiprocessor parallel computing systems and a byte serial  SIMD processor parallel  architecture  is used  for parallel  array processing with a  simplified  architecture adaptable  to  chip  implementation  in  an  air  cooled environment.  The array provided is an N dimensional array of byte wide processing units each coupled with an adequate segment  of  byte  wide  memory  and  control  logic.   A partitionable  section  of  the  array containing  several processing units are contained on a silicon chip arranged with  "Picket"s,   an  element  of  the  processing  array preferably consisting of combined processing element with a local  memory  for  processing  bit  parallel  bytes  of information in a clock cycle.  A Picket Processor system (or Subsystem) comprises an array of pickets,  a communication network, an I/O system, and a SIMD controller consisting of a  microprocessor,   a  canned  routine  processor,  and  a microcontroller that runs the array.The Picket Architecture for  SIMD  includes  set  associative  processing,  parallel numerically  intensive  processing  with  physical  array processing similar to image processing  a military picket line analogy fits quite well.  Pickets, having a bit parallel processing  element,  with  local  memory  coupled  to  the processing   element   for   the   parallel   processing   of information  in  an  associative  way  where  each  picket  is adapted to perform one element of the associative process. We have provided a way for horizontal association with each picket.  The memory of the picket units is arranged in an array.  The array of pickets thus arranged comprises a set associative memory. The set associative parallel processing system on a single chip permits a smaller set of 'data' out of  a  larger  set  to  be  brought  out  of  memory where  an associative  operation  can  be  performed  on  it.   This associative  operation,  typically  an  exact  compare,  is performed on the whole set of data in parallel, utilizing the Picket's memory and execution unit.

Title: Stock divider
Inventor: LONERGAN MARK A
IPC: B23F23/08
Filed: 1992-02-05
Abstract: A grinder for form grinding gear teeth in which a work gear is positioned rotationally by a computer controlled drive. A sensitive probe in known angular relation to a grinding wheel about the axis of the gear is positioned at random in any tooth space in each of a series of probing operations carried out at a plurality of spaced points along the length of a tooth space. In the probing operation at each point, the probe senses the angular positions of the gear when the gear is driven in opposite directions into probe actuating positions of adjacent tooth surfaces and the computer computes one half of the angular difference between the two angular positions. The computer then averages the one half angular difference computed at each of the plurality of spaced points to provide a stock divided grinding position. The gear may then be rotated to the stock divided position for grinding. tonnes per day

Title: System and method for checking the aim of a vehicle headlamp
Inventor: OLDWEILER WILLIAM E
IPC: G01M11/06
Filed: 1992-02-17
Abstract: Abstract A system and method for checking the aim of the high and low beams of a vehicle headlamp are provided.  The system comprises a vehicle position locator adapted to be centered under the vehicle, and a target screen located at a predetermined distance from the headlamp of a vehicle centered on the locator.   A laser/prism subassembly is mounted to the locator for lateral and vertical movement relative to the vehicle.  The prism directs the laser beam toward the headlamp when it is positioned in front of the laser. A plurality of photosensors on the target screen sense the intensity of a light beam from the headlamp, and meters on the target screen indicate comparisons of the levels of intensity of portions of the beam sensed by the individual photosensors.  The method comprises the steps of directing the laser beam at the center of the headlamp lens with the prism,  fixing the position of the  laser with respect to the headlamp lens,  and moving the prism to redirect the laser beam at the target screen to establish an origin point for a properly aimed headlamp. The vehicle headlamp is then shined upon the photosensors.   If the headlamp beam intensities sensed by the photosensors have the proper comparative distribution, the meters will verify the proper aim of the headlamp.  If not, the target screen is moved until the meters show an acceptable aim indication. The steps of directing the laser light beam at the center of the  headlamp  lens,  fixing  the  laser  position,   and redirecting the laser light beam at the target screen are then repeated.   The distance on the screen between the origin point and the location of the laser beam after moving the screen indicates the amount of headlamp misalignment. The headlamp is accepted only if this distance is within prescribed limits.
