Patent CA-2010208-A1 (CA)
Title: Paper feed system
Inventor: BARRUS GORDON B
IPC: B41J11/30
Filed: 1990-02-16
Abstract: ABSTRACT OF THE DISCLOSURE Each of a pair of spaced apart paper feed mechanisms within the paper feed system of a dot matrix line printer has opposite upper and lower portions thereof slightly angled relative to each other and disposed on opposite sides of and close to an elongated print station having a platen at one side thereof on which the paper feed mechanisms are mounted.  Each paper feed mechanism is locked in a desired position on the platen using a manually operated lever arm arrangement having a mechanical advantage.    Phasing or pitch adjustment between the opposite portions of each paper feed mechanism is accomplished either by adjustment of an eccentric hub rotatably mounting a pulley which engages an endless belt between the opposite portions or by adjustment of a cam which engages a pivotable lever arm assembly having a belt engaging pulley at an opposite end thereof, in combination with an opposite spring mounted pulley which bears against the inside of and tensions the endless belt.  A knob rotates a common shaft on which the eccentric hub or the cam of each paper feed mechanism is mounted to accomplish phasing adjustment.         The opposite portions of each paper feed mechanism terminate in ramps which are angled to facilitate partial but not complete withdrawal of pins on the belt from apertures at the edges of the print paper as each pin advances to the end of the paper drive mechanism.  A lug arrangement at the end of the ramp prevents the toothed underside of the belt from slipping off of the meshing teeth of a pulley about which the belt extends.  Slide members resiliently mounted underneath hinged covers extending over the opposite portions of each paper feed mechanism bear against and maintain the edges of the paper in contact with the belts.  Guides in the form of parallel ridges on a ribbon guide within the print station guide a length of paper introduced onto one portion of the paper feed mechanism through the print station and onto the other portion.

Title: Photochemical treatment of blood vessels
Inventor: BERNS MICHAEL W
IPC: A61N5/06
Filed: 1990-03-14
Abstract: PHOTOCHEMICAL TREATMENT OF BLOOD VESSELS            Abstract of the Disclosure A method for treating blood vessels to destroy the blood vessel without damaging surrounding tissue.   The method  involves  introducing  a  photoreactive  compound into  the blood  flowing through the blood vessel  and allowing the photoreactive compound to accumulate in the blood  vessel  wall.    The  photoreactive  compound  is activated by exposure to radiation prior to accumulation of the reactive compound into surrounding tissues.  The activation  of  the  photoreactive  compound  prior  to movement  into  surrounding  tissues  provides  selective destruction of blood vessels while limiting destruction of surrounding tissues.

Patent CA-2015821-A1 (CA)
Title: Flexible multiplexer
Inventor: EHRICKE CLAUS
IPC: H04J3/16
Filed: 1990-05-01
Abstract: ABSTRACT OF THE DISCLOSURE            A flexible multiplexer enables a liberal grouping and distribution of time sections of digital multiplex signals on dedicated lines with increasing numbers of line units on the subscriber side and the line side.   The accommodation of the numerous voice/data and identifier multiplex signal lines between the line units thereby causes increasing numbers of problems.   A reduction of the multiplex signal lines occurs when all channel units in the line units of the subscriber side and all line units of the line side are no longer connected to each multiplex line, but groups of line units of the subscriber side and all line units of the line side are each respectively connected via an incoming and an outgoing voice/data multiplex signal line to a voice/data switching matrix network and are connected via an incoming and an outgoing identifier multiplex signal line to an identifier switching matrix network.  Such a flexible multiplexer enables connections between line units of the subscriber side, enables a grouping and separating of multiplex signals between line units of the subscriber side and of the line side and also enables a channel distribution between line units of the line side.

Title: Marine propulsion device
Inventor: BINVERSIE GREGORY J
IPC: B63H20/00
Filed: 1990-09-12
Abstract: ABSTRACT OF THE DISCLOSURE          A marine propulsion device includes a support adapted to be attached to a boat hull and a propulsion assembly including a propeller adapted to be driven by an engine.  The propulsion assembly is connected to the support for vertical pivotal movement relative thereto and a hydraulic tilt cylinder and piston assembly is connected at one end to the support and has a second end connected to the propulsion assembly. The piston is movable toward the other end of the cylinder when the one end is pressurized to tilt the propulsion assembly upwardly.  At least one trim cylinder is fixed relative to the support and includes a trim piston reciprocally mounted on the cylinder and releasably engageable with the propulsion assembly.  Actuation of the propeller while the propulsion assembly is tilted upwardly is operative to force the propulsion assembly downwardly against the piston.  A valve is operable when the piston is forced toward the one end of the cylinder to vent hydraulic fluid from the one end of the cylinder and an orifice is provided for controlling the flow rate of fluid through the valve to prevent the rapid descent of the propulsion assembly.

Title: Data redundancy and recovery protection
Inventor: SCHULTZ STEPHEN M
IPC: G06F11/14
Filed: 1990-11-01
Abstract: Abstract A method for detecting the presence of a replacement disk in a fault tolerant, intelligent mass storage disk array subsystem having a microprocessor based controller in  a  personal computer system and rebuilding the replacement disk independent of the computer system processor.   The method calls for the microprocessor controller to run a disk array check at system powerup or at specified intervals at which will detect the existence of a replacement drive.  The microprocessor then builds a series of disk drive commands which attempt to read every sector on the replacement disk.  The read commands will return a null data read, indicating that the sector must be restored.  The microprocessor controller converts the replacement  read  commands  for all  sectors on the replacement  disk  to  write-restore  commands.   The microprocessor executes the write commands and restores the data to the replacement drive.

Title: Essentially passive method for inverting the orientation of a dual spin spacecraft
Inventor: FONG HERBERT S
IPC: B64G1/38
Filed: 1991-01-09
Abstract: ABSTRACT       An essentially passive and "fuel-less" method for inverting the orientation of a preferably nutationally stable, dual spin spacecraft disposed in an inclined orbit, includes the steps of increasing the rotational speed of (i.e., "spinning up") the spacecraft's despun platform and decreasing the rotational speed of (i.e., "spinning down") the spacecraft's rotor, to thereby generate, via product of inertia coupling, a transverse torque of sufficient magnitude to temporarily destabilize the spacecraft and cause the spacecraft spin axis, which is the minimum moment of inertia axis of the spacecraft, to diverge and precess through a flat spin orientation and towards a final, inverted orientation, e.g., disposed at a precession angle of 180° relative to the initial orientation of the spacecraft spin axis. Normally, prior to the spacecraft spin axis reaching the final, inverted orientation, the spin axis encounters and is "stuck at" a barrier nutation angle beyond which further precession of the spacecraft spin axis is not possible without the implementation of a final acquisition procedure, which includes the steps of detecting the occurrence of the spin axis reaching the barrier nutation angle, and in response thereto, instituting limit cycle rotational motion of the platform, to thereby render non-secular the rotational motion of the platform, whereby the spacecraft damping system is brought into its pull-in or effective operating range for penetrating the barrier nutation angle, in order to achieve acquisition of the final inverted orientation of the spacecraft spin axis. Limit cycle rotation of the platform is preferably effectuated by means of applying a first and a second series of torquing pulses to the spacecraft despin motor suitable for reducing the rotational speed of the platform, the first series of pulses being of larger magnitude than that of the second series of pulses.
