Patent CA-1080045-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE   A stabilized life raft utilizing a fluid filled depending buoy chamber for overall stabilization and including as improved features thereon a peripheral skirt chamber which fills with the raft supporting fluid upon deployment of the raft and serves as a temporary stabilizing means while the buoy chamber becomes filled. The buoy chamber includes baffle means to impede the flow of the stabilizing fluid from one portion of the chamber to another in the event of a sudden weight shift within the raft. Improved valve means permit a more rapid inward flow of fluid upon deployment of the raft and yet prevents outward flow in instances where the buoyant raft is suddenly thrust upwardly by elements such as waves. The raft, because of the particular placement of the various structural elements in conjunction with the placement of the survival gear and inflation system, is automatically self-righting.

Abstract: ABSTRACT           A method of forming two diverging beams of energy from a single beam of energy including the steps of splitting the single beam of energy into an externally reflected beam and an internally transmitted beam at a first surface on a wedge-shaped energy beam splitting device; splitting the internally transmitted beam into an internally reflected beam and an externally transmitted beam at a second surface of the wedge-shaped energy beam splitting device, and substantially totally reflecting the internally reflected beam between the first and second surfaces until the internally reflected beam reaches an end of the wedge-shaped energy beam splitting device.  The above method may further include steps parallel-ing the above steps wherein two diverging beams of energy are formed from a second beam of energy impinging on the second surface and then combining the two diverging beams with the two diverging beams formed from the beam of energy split by the first surface, to form first and second combined beams.

Abstract: Title of the Invention INITIALIZING MEANS FOR A BUS-ORIENTED DATA PROCESSING SYSTEM EMPLOYING FIRMWARE-CONFIGURED                      MODULES            Abstract of the Disclosure In order to initialize firmware-configured modules, such as the system processor and input/output controllers, in a data processing system, a service processor is employed.  The service processor, which itself normally functions as a power-ful input/output controller, includes an instruction memory comprised, at least partially, of non-volatile memory means such as a read-only memory.  Upon utilization during actual start-up or when changing the configuration of the data pro-cessing system under program control, an instruction counter in the service processor is forced to a predetermined address in the non-volatile section of the instruction memory.  The predetermined location contains the first instruction in a boot-strap routine by which a loader and the necessary firmware may be obtained from a diskette coupled to the service processor The firmware is then distributed among the firmware-configured modules throughout the system.  When the system is configured, the service processor itself is reconfigured to function as an input/output controller for peripherals coupled to it.

Abstract: ABSTRACT OF THE INVENTION         Method and apparatus for controlling the power output and speed of a high slip motor associated with a pumpjack unit.          The stators of the high slip motor are automatically connected in various different configurations to provide the optimum torque and speed at which the pumpjack unit should be reciprocated with respect to the varying downhole pumping conditions.  A novel con-trol circuitry is connected between the motor starter and the motor stators.  The control measures the power drawn by the sta-tors and selects the most optimum configuration thereof for the load required by the pumpjack.  This selection operates the motor in the lowest possible torque mode, which is considered the best electrical and mechanical operation of the pumpjack apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE         A brake system includes a master cylinder which is operable to communicate pressurized fluid to a wheel assembly in order to brake the latter.  The wheel assembly is capable of spinning or skidding under exces-sive acceleration or deceleration, respectively, and an electronic control unit cooperates with a modulator valve and a pressure source to compensate for spinning or skidding by controlling the communication of pressurized fluid from the modulator valve to the wheel assembly.  The modulator valve communicates with the pressure source and the master cylinder and includes a first bore for slidably supporting a piston assembly and a second bore for slidably supporting a plunger.  The piston assembly cooperates with a modulator valve housing to define a storage chamber and the pressure source is operable to move the plunger to a position communicating the master cylinder and the wheel assembly with the storage chamber.  The piston assembly comprises at least three pistons, two of which define pressure chambers and the third defines the storage chamber.  At least two solenoid valves are coupled to the control unit so that one of the solenoid valves is actuated upon skidding to vent one of the pressure chambers and the other solenoid valve is actuated upon spinning to vent the other pressure chamber.  A first piston includes a projection extending through a bore in the second piston to oppose a third piston.
