Patent CA-2008686-A1 (CA)
Inventor: PRATT RICHARD L
IPC: H02P27/06
Filed: 1990-01-26
Abstract: A motor control method is disclosed in which a drive motor is connected to an adjustable frequency power supply in which the frequency of the power supplied to the motor can be selectively varied.  While the motor is running at a constant speed as determined by the frequency of the power supplied to the motor, the value of the current being supplied to the motor by the power supply is sensed and an actual current signal representative of said actual current value is produced.  A reference current signal which is representative of a selected maximum current value and thereby a maximum load at which the motor speed may be increased is also provided.  The actual current signal is compared with the reference current signal and if the former is less than or equal to the latter, an output signal is provided.  In response to the output signal resulting from the comparison, the value of the actual frequency of the power supplied to the motor is increased to a preselected value so that the motor speed also increases.  The accel-eration rate of the motor while its speed is increasing may also be changed.

Title: Bowling dartboard game
Inventor: TURNER DAVID W
IPC: F41J3/00
Filed: 1990-01-29
Abstract: ABSTRACT OF THE DISCLOSURE          A dart game toy that is suitable for simulating the popular bowling games,  it  comprises  a  dart,  and  a target board with representations of bowling pins.  One game  play  consists  of  a  set  of  sequential  dart throwings being thrown by one player.  The objective is to have the initial dart landed on the strike target zone on the target board.  If the dart is landed in the strike target zone, the player scores a "strike" as in bowling, if outside the strike target zone the player will throw a second dart at other target zones in an attempt to score a "spare" as in bowling by landing a dart in a target zone which when added to the results of the  first throw would count as  a spare.   When simulating ten pin bowling two dart throws would be allowed,  and when simulating five pin bowling three dart throws would be allowed.  The games rules are such that players will use regular bowling score sheets and a game will consist of ten plays by each player as in bowling.

Title: Buck derrick drain valve
Inventor: DERRICK ELWOOD B
IPC: E03B7/08
Filed: 1990-08-17
Abstract: ABSTRACT The Buck Derrick Drain Valve is a form of check valve to prevent liquid back flow in drain lines that are round pipe design. The device is designed to fit inside the opening of the drain pipe at the entrance of the drain, and is secured in place by three set screws or bolts. The set screws or bolts are held in placeby tee nuts. The device requires no major tools to install. The Buck Derrick Drain Valve is designed as a low-cost check valve to prevent liquid back flow that occurs in round pipe drain lines. It is known that there are other types of valves that serve the same purpose, but are more complicated and not reasonable. The Buck Derrick Drain Valve is made of fibreglass, plastic,or metal. As all drains are designed for down-flow and not up-flow, it is impor-tant that the down-flaw has as little obstruction as possible.

Title: Magnesium die casting machine
Inventor: YAFFE STEPHEN
IPC: B22D17/04
Filed: 1990-08-30
Abstract: A machine for producing metal die castings is disclosed and comprises a crucible that incorporates an injection pump assembly which is mounted in such a way as to clear the upper access of the crucible to facilitate cover sealing and removing.  The crucible is located in a furnace and is reciprocable to move the injection barrel and nozzle to and from a mold.  The injection barrel is immersed in the crucible beneath the level of the molten metal to enhance heat transfer between the barrel and injected metal.  The separate plunger and shot assemblies are located in the pump body in a "V" configuration so that maintenance of these units can be carried out without exposing the top of the furnace to the atmosphere.  The plunger and shot assemblies include sealing means in connection with their actuating mechanisms to avoid molten metal splashing outside of the crucible when they are moving in an injection operation and to prevent the ingress of moisture, hydraulic fluid or the like into the crucible or injection chambers.  The apparatus is particularly suitable for use with high melting point alloys such as magnesium.

Inventor: YANAGI SHIGENORI
IPC: G11B7/095
Filed: 1990-08-30
Abstract: When a light beam of a reference optical head correctly tracks on the center of a proper track, deviation, due to an optical head assembling error or an optical disk eccentricity, of a light beam of a non-reference optical head from the center of said proper track is memorized in advance as  bias information.    At a time of a seek control or a track jump control, the non-reference optical head is controlled to move along a track with said bias information, so that not only the reference optical head but also the non-reference optical head correctly track on the proper aimed track, when a seek control or a track jump control is performed.    This invention enables both the light beam of the reference optical head and the light beam of the non-reference optical head to correctly track on a proper track without being affected by neither any optical head assembling error nor any optical disk eccentricity.
