Title: Small Watercraft Automatic Steering Apparatus and Method
Inventor: FORD DOUGLAS W
IPC: B63H25/22
Filed: 1995-09-12
Abstract: An automatic steering system (10) has a control subsystem (14) that employs a yaw rate control loop (90) and a steering control loop (92) to drive a hydraulic subsystem (12) in which the deflection rate of a steering actuator (16) is controlled without need for either a steering actuator angle sensor or an electronic steering bias integrator.  Rather, the control subsystem employs a proportional rate servosystem to control the steering actuator deflection rate and a double-acting hydraulic cylinder (34) to provide the steering bias integral action.  The control subsystem employs an electric compass (96) to generate heading data that are stored in a heading command register (102).  An heading error is formed by calculating a difference between a desired heading and the current heading.  A rate taker (94) generates  a yaw rate feedback signal by differentiating changes in the current heading.  The heading error and yaw rate feedback signal are processed to generate a steering rate command to which the steering control loop responds by pumping hydraulic fluid at a rate proportional to the steering rate command into the hydraulic cylinder to deflect the steering actuator of an outboard motor (18).

Title: Molecular diagnosis of familial adenomatous polyposis
Inventor: KINZLER KENNETH W
IPC: C12Q1/68
Filed: 1994-12-13
Abstract: A two-pronged method for diagnosis of genetic diseases can detect mutations in about 87 % of familial adenomatous polyposis (FAP) patients. One part of the diagnosis method employs in vitro protein synthesis from surrogate genes created by amplifying either cDNA or genomic DNA. The second part of the diagnostic method employs an allele-specific expression assay which distinguishes the amount of mRNA expressed in vivo from each of a patient's two alleles. These approaches are readily applicable to the diagnosis of other genetic diseases.
Patent CA-2180257-A1 (CA)
Title: Coin discriminator with offset null coils
Inventor: BELL EDWARD H
IPC: G07D5/08
Filed: 1994-11-01
Abstract: A  discriminator  for coins and tokens monitors the extent  to  which  an alternating  electromagnetic field is coupled  through  a deposited  coin  (22) and  a reference coin (24) as  the deposited  coin passes along a  feed  path (40).  A first electromagnetic  field  is incident on a reference coin along an  axis (42) normal to  the referene  coin and displaced  from  a  midpoint (44) of  the  reference coin.  As  the deposited coin  moves  though  a second   electromagnetic field traversing feed path, the deposited  coin  passes two positions at which the second  electromagnetic field is aligned to  the  deposited coin  to a  same degree as the first  electromagnetic  means is aligned to the  reference coin.  The  electromagnetic fields preferably are provided by two series connected coils (32, 34) in a stack, and the fields passing through the coins are added at opposite polarity by a receiver coil (38) placed between the series connected  coils (and also between the sample coin and the deposited coin).  The received signal is rectified, filtered and digitized, whereupon at least one of the following may be  ascertained: the received waveform shape, the maximum and minimum peak levels, and the timing  characteristics.  This  ascertained information and  detected data of an optical code on the deposited coin can be compared to stored criteria, for passing or sorting coins.
Patent CA-2180797-A1 (CA)
Title: Tire cure bladders containing polytetrafluoroethylene powder and use thereof
Inventor: PATITSAS GEORGE PHILEMON
IPC: B29C33/62
Filed: 1996-07-09
Abstract: Expandable bladders for use in curing presses for hydrocarbon rubbers, such as pneumatic tires, are a crosslinked elastomer composition comprising isobutylene repeat units and including a fluorinated ethylene polymer added in particulate form and thereafter dispersed throughout the bladder. These fluorinated ethylene polymer may or may not form fibers. The bladders may further comprise graphite. A preferred isobutylene elastomer is a brominated copolymer of from 80 to 99 weight percent isobutylene and from 1 to 20 weight percent paramethylstyrene. The bladders have enhanced lubricity, reduced adhesion to cured tire innerliners, better resistance to cracking during flexing, and have lower tension set than similar compositions without fluorinated ethylene polymers. The above enhancements allow hydrocarbon rubbers such as tires to be molded with fewer defects caused by abraded or deformed bladders. They also enhance the useful life of the bladder reducing the cost of tire curing.

Patent CA-2191554-A1 (CA)
Inventor: GRIEPENTROG DAL FRANK
IPC: H04N9/73
Filed: 1995-05-30
Abstract: Video signals to be displayed are applied via a video driver amplifier (50) to the cathode electrode (32, 34, 36) of a kinescope (30). A beam current sensor (56), also coupled to the cathode electrode (32, 34, 36), provides a beam current indicating signal (S6). An AKB regulator (60), responsive to the beam current indicating signal (S6), supplies a black level correction signal (Ia) to the driver amplifier (50) for regulating the black level of images displayed by the kinescope (30). A screen grid supply system (70, 90) is provided for controlling the G-2 (screen grid) voltage of the kinescope (30) as a predetermined function of the black level correction signal (Ia) thereby forming with the AKB regulator (60) a dual feedback loop for providing black level regulation by both the driver amplifier (50) and the screen grid (G2) thereby maximizing or extending the overall black level control range.  Consequently, the high voltage screen control potentiometer (97) normally required for setting screen grid bias may be completely eliminated if desired, or, in applications where it is retained, no adjustments are required subsequent to an initial adjustement.
