Title: Electrical control circuit for a bidirectional motor
Inventor: ETSCHEIDT RONALD J
IPC: H02P7/00
Filed: 1990-01-24
Abstract: ABSTRACT OF THE DISCLOSURE            A field installable motor operator for a circuit breaker includes a bidirectionally controllable motor that is coupled through a torque limited module to a circuit breaker operating mechanism.  The motor is bidirectionally driven by a transistor switching bridge that supplies output current in reversible flow directions through one of the windings of the motor to the input of a rectifier bridge that supplies the other winding with currents that flow in the same direction. The torque limited module includes a centering and spacing ring which precisely confines the clutch elements to provide consistent torque.  The motor is supplied with a current pulse of 250 milliseconds duration that is longer than the time required to fully operate the breaker. The clutch slips when breaker operation is completed and permits the motor to overrun without damage.

Patent CA-2011053-A1 (CA)
Title: Steel plate with organic coating having improved corrosion resistance
Inventor: OGISHI HIDEO
IPC: B05D7/24
Filed: 1990-02-27
Abstract: The improved corrosion-resistant steel plate with an organic coating comprises a steel plate having a zinc or zinc alloy plate layer which is overlaid with a chromate film which in turn is coated with an organic resin paint film. The organic resin coat comprises an epoxy resin having a dialkanolamine incorporated into its bisphenol A skeleton, an amino resin, and silica. The dialkanolamine combines with the amino resin to provide satisfactory curability at low temperatures; at the same time, it combines with the silica to provide a satisfactory film reinforcing effect. The organic coat formed of this composition can be effectively cured at low temperatures and yet it will neither dissolve nor soften upon swelling under the action of the alkali that is generated during cationic electrodeposition at the interface between the electrodeposited film and the organic coat. Thus, the organic coat has good paint adhesion, high corrosion resistance, as well as good workability and weldability and makes the steel plate suitable for use as an automotive part after painting. If the proportion of trivalent chromium in the chromate film and the amounts of zinc oxide and silica sol to be incorporated as additives are properly adjusted, the organic coating will exhibit satisfactory resistance to chromium dissolution and hence its paint adhesion and corrosion resistance are further improved to make the steel plate more suitable for use as an automotive part after painting.

Patent CA-2012883-A1 (CA)
Title: Dinghy rigger
Inventor: SANDROW MARTIN S
IPC: B63B23/32
Filed: 1990-03-22
Abstract: ABSTRACT OF THE INVENTION    A smal boat or dinghy rigging mechanism is provided advantageously designed to permit the expeditious recovery, hoisting and stowing of a small boat or dinghy in an upright position at the stern of a main vessel.  The apparatus of the invention is devised to be readily detached from the main vessel and stowed so that any unsightly presence of the equipment when it is not being used is obviated.  The rigger equipment may be detachable affixed for use directly on the transom of a vessel or adapted to be detachably secured at the trailing edge of a platform such as a swim platform that is behind the transom.  Because the mechanism is devised to dip into the water allowing the small boat or dinghy to be floated into position on the arms of the rigging apparatus, it substantially facilitates the recovery of such craft and obviates any heavy lifting or exertion of the kind frequently encountered by a user in operations of this kind.  Also because the dinghy or small boat is recovered while being maintained upright, is supported underneath, stored at the stern of the main vessel and secured in an upright position, the outboard motor or other depending propulsion or steering equipment need not be removed from the dinghy or small craft in order to recover and stow the small craft on the main vessel.
Patent CA-2012917-A1 (CA)
Inventor: BATEMAN ANDREW
IPC: H04B1/68
Filed: 1990-03-23
Abstract: In deriving a control signal for recombining the parts of the spectrum separated by a frequency notch in transparent tone-in-band signals, cross-correlation products give rise to undesirable frequency and phase fitter. In a receiver which overcomes this problem an input signal E containing the notch is passed to two first mixers and then portions corresponding to the lower and upper portions of the input spectrum are selected by two mirror filters before being translated in frequency by two second mixers to a final output band in which the notch is eliminated. Two selection filters select parts of the spectra at the outputs of the first mixers which correspond to an overlap region of the said lower and upper portions when derived in a transmitter and apply them to a control-signal mixer. A control signal for the second mixers is derived from the output of the control-signal mixer by noise filtering and frequency division by two. The above mentioned problem is overcome by giving the mirror filters transfer functions H1-(f) and H1+(f) which are the same as the transfer functions of mirror filters in the transmitter which produced the notch and by giving the selection filters transfer functions H2-(f) and H2+(f) which satisfy the relationships H2-(f) = ~H1+(f)2 and H2+(f) = ~H1-(f)2.

Abstract: A multiple television screen processing circuit having a teletext function.  The circuit comprises a TV video signal generator for producing a TV video signal, a PIP signal generator for producing a PIP signal, an ON screen display signal generator for producing an ON screen display signal, and a teletext signal generator for producing a teletext signal.  Each is controlled by a microcomputer.  There is a selection controller for combing logically the selection-controlling signals.  A signal selector selects and outputs, under the control of the selectioncontrolling signals and the output signal of the selection controller, the TV video signal, the PIP signal, the ON screen display video signal or the teletext signal.  There is an amplifier for amplifying the output signal of the signal selector.  A Braun tube displays the output signal of the amplifier.  Thus, the TV video signal, the PIP signal and/or ON screen display signal can be simultaneously or separately displayed on a screen. The teletext signal can be displayed on a screen with the ON screen display signal; or the teletext signal can be displayed on a screen with the PIP signal and the ON screen display.

Title: Restraining protective seat for infants
Inventor: MINAMI YOSHIHIKO
IPC: B60N2/28
Filed: 1990-06-28
Abstract: ABSTRACT    A protecting member (10), which does not allow a seat belt (7) to come into direct contact with a seat main unit (2) when the seat belt (7) is tightened, is interposed between the seat belt (7) and the seat main unit (2).  An engaging mechanism (2c, 10d, 11, 12), which causes the protecting member (10) and the seat main unit (2) to engage when the vehicle undergoes deceleration in excess of a predetermined value, is provided.  As a result, the seat belt (7) does not directly engage the seat main unit (2) when an infant restraining protective seat (1) is secured to a vehicle seat by pulling the seat belt (7) tightly upon passing it through mounting holes in the seat main unit (2).          Accordingly, the reclining angle of the seat main unit (2) can be adjusted with the seat belt left (7) in the tightened state.  Since the protecting member (10) and the seat main unit (2) are engaged by the engaging mechanism (2c, 10d, 11, 12) when the vehicle undergoes a large amount of deceleration, the seat main unit (2) can be held reliably without undergoing a change in reclined attitude.
