Patent CA-2012457-A1 (CA)
IPC: H01H51/22
Filed: 1990-03-19
Abstract: A polarized electromagnetic relay is designed to have a minimum height as less as that of an electromagnet block constituting one major part of the relay.  The relay includes a base which is formed to receive the electromagnet block and to have a set of fixed contacts.  The electromagnet block includes a generally U-shaped yoke with a pair of opposed legs connected by a center core and at least one excitation coil wound around the center core.  An armature block is mounted within the base together with the electromagnet block and comprises an elongated armature extending over the opposed pole legs and pivotally supported for movement between first and second positions about a pivot axis.  The armature block carries a movable contact for contact selectively with one of the fixed contacts in response to the armature movement between the first and second positions.  The armature is magnetically coupled to the pole legs by means of a permanent magnet such that the armature block responds to polarity change in the current energizing the excitation coil to move between the first and second positions.  The permanent magnet is disposed in the bottom portion of the base within the plane of the pole legs.  The armature block is disposed above the permanent magnet in such a manner that the armature block and the permanent are stacked within the height of the electromagnet block.

Title: Fuel metering method and apparatus
Inventor: WOODY JOHN C
IPC: F02M5/08
Filed: 1990-10-25
Abstract: Method,  system and apparatus for metering fuel to an internal combustion engine via a carburetor having a mixture conduit with a venturi therein.  A main fuel nozzle supplies fuel to the venturi of the carburetor in response to the static pressure drop induced across an associated main fuel flow controlling restriction by the engine intake induced air flow through the carburetor mixture conduit. A pitot tube is disposed in the venturi with an opening facing upstream in a zone of maximum air  flow through  the carburetor venturi.   A vent passageway system connects the pitot tube to a single closed air chamber cooperable with either a diaphragm or a float to regulate operation of an inlet valve controlling flow of fuel to a main fuel controlling restriction.   The adverse effect of engine intake induced tuning pressure wave forms in the mixture conduit of the carburetor transitting the venturi is eliminated, reduced or modulated by the dynamic pressure exerted by said tuning waves at the pitot tube and transmitted by the vent passageway to said chamber and to said main fuel restriction.

Abstract: FOUR-WAY SLIDE VALVE                   ABSTRACT OF THE DISCLOSURE   A four-way slide valve including an elongated valve body (10) having an inlet port (15), an outlet port (16), and two working ports (17, 18).  A slide assembly (28) within the body is movable longitudinally to alternatively interconnect the outlet port with one or the other of the working ports.  The slide assembly carries two longitudinally spaced-apart first and second pistons (33,35) which define first and second chambers (38,39) between the pistons and  their  respective  ends  of  the  valve  body.    Passageways (41,49,50) within the slide assembly provide communication between the first chamber and the outlet port, and a control device, such as a pilot valve (59) within the valve body, selectively provides communication between the second chamber and either the inlet port or the outlet port, so as to cause the slide member to move to one of its extreme positions or the other.   The first piston is smaller than the second piston, the first chamber is in constant communication with the outlet port, and the region (40) between the pistons is in constant communication with the inlet port.  The movable armature of a solenoid actuator (64) acts directly upon the pilot valve within the slide valve body, the movement of the armature in one direction causing movement of the slide assembly in the opposite direction.  A slide member (42) forming part of the slide assembly, slides upon a flow plate (21) which contains the outlet and working ports,  the face of the slide member opposite the flow plate being in communication with the outlet port.

Title: Attachable electro-impulse de-icer
Inventor: ADAMS LOWELL J
IPC: B64D15/16
Filed: 1990-12-18
Abstract: ATTACHABLE ELECTRO-IMPULSE DE-ICER     Abstract An attachable electro-impulse de-icer for de-icing an aircraft structural member includes an inductor coil disposed in proximity with the outer surface of the structural member.  The coil is supported by a flexible, ice-accumulating support member (surface ply)  that permits the coil  to move relative  to the structural member.   Preferably the coil and support member are formed in an integral construction that can be attached to the leading edge of the structural member.  The coil and support member are rapidly, and forcefully, displaced away from the structural member upon passing a short-duration, high-current pulse through the coil.  The current flow creates an electromagnetic field that induces eddy currents in the support member (if made of metal), and the structural member (if made of metal).  Upon collapse of the electromagnetic field in the coil, the support member is pulled rapidly to  its rest position adjacent the structural member.          Alternative arrangements are provided wherein (1) a metal target is disposed in proximity with the outer surface of the coil,  (2) a metal target is disposed in proximity with the outer surface of the structural member, and (3) an additional target (doubler) is attached to the inner surface of the structural member.

Title: Optical pickup device
Inventor: MIYAKE TAKAHIRO
IPC: G11B7/1398
Filed: 1991-04-18
Abstract: ABSTRACT OF THE DISCLOSURE    An optical pickup device having an optical  system provided with at least a light source, a shaping prism, an diffracting element and a photodetector.  The light source projects  light  whose  intensity  distribution  has  an elliptical shape in its cross section orthogonal to the optical axis.  The shaping prism directs the light to a recording medium after shaping the intensity distribution thereof into a circular shape.  The diffracting element has diffraction regions formed by at least one division line substantially parallel to a reference direction.  The light  reflected  from  the  recording  medium  forms  an elliptical bright portion on the diffracting element.  The photodetector is divided by a plurality of division lines, at least one of which is substantially parallel to the reference direction.   The diffracting element diffracts the  reflected  light  so  as  to  converge  it  on  the photodetector.  Here, a hypothetical line extending from a projecting point of the light source through the center of a light-receiving face of the photodetector is also set to be parallel to the reference direction.  For example, when the shaping prism is to shape the intensity distribution having the elliptical shape with respect to its minor axis direction,  the optical  system is arranged  so that the minor  axis  of  the  bright  portion  is  parallel  to  the division line of the diffracting element.   Thus,  it is possible to always obtain an accurate focusing control signal.
