Patent CA-2019073-A1 (CA)
Title: Radio receiver
Inventor: HALES JEFF
IPC: H01P7/00
Filed: 1990-06-15
Abstract: ABSTRACT          A radio receiver includes a filter having one or more filter sections.  Each filter section has a shield provided with several helical resonators.  Each helical resonator has a quarter-wavelength transmission line wound in the form of a helix with the transmission lines adjacent resonators being wound in opposite directions and being grounded at opposite ends, whereby the frequency response of the filter section has a transmission notch on the high frequency side of the filter section passband.          At least one grounded shielding pin is disposed between adjacent helical resonators at such locations whereby the transmission notch in the frequency response of the filter section is steered to be coincident with or near to the image frequency.  By using such a filter section as distinct from one using conventional helical resonators a transmission notch is generated on the high frequency side of the passband and by steering the transmission notch in the frequency response to be coincident with or near to the image frequency, extra image frequency rejection is gained.          As a consequence a reduced number of helical resonators may be utilised to obtain the required image frequency rejection than if conventional helical resonators were used.  Moreover the use of shielding pins avoids the costs that are associated with the use of partitions in conventional helical resonators.

Title: Method and apparatus for controlling a blower motor in an air handling system to provide constant pressure
Inventor: BEIFUS BRIAN L
IPC: F04D27/02
Filed: 1991-01-17
Abstract: Apparatus and method for controlling a motor having a stationary assembly with a plurality of winding stages for carrying motor current and further having a rotatable assembly in driving relation with a blower in an air handling system. The apparatus provides control of the pressure over a range of flow restrictions to maintain air pressure in the system at a relatively constant preselected level. The apparatus receives a preselected pressure signal representing the preselected air pressure level. A microprocessor, responsive to both the preselected pressure signal and a motor speed signal, generates a desired torque signal which is a function of the preselected pressure signal, the speed signal and a previous desired torque signal. The desired torque signal is compared to a signal representing motor torque and a comparison signal representing the comparison is generated. An IC control applies a motor voltage to one or more of the winding stages at a time in accordance with the comparison signal and commutates the winding stages in a preselected sequence to rotate the rotatable assembly. As a result, the blower is driven by varying the motor speed according to motor torque (i.e., torque compensated speed) to maintain substantially constant air pressure in the system at the preselected rate substantially independent of variations in the flow restrictions.
Patent CA-2036705-A1 (CA)
IPC: E04C3/07
Filed: 1991-02-20
Abstract: A hollow,  tubular,  elongated beam is made by roll-forming an elongated strip of sheet metal into a generally  rectangular  cross-section  shape  with  its opposite edge portions overlapped to form a double ply beam wall along one side of the beam.   The plies are adhesively  secured  together  by  an  adhesive  material inserted between them.   The  sheet metal  is  initially rolled into a U-shaped channel having a base and opposite walls.  An integral,  interior ledge is formed in,  and extends along the length of, one of the channel walls.          Then, the edge portion of the opposite channel wall is bent to form an inner ply that overlaps and closes the open channel, to form the tubular shape, with its free edge abutted against the ledge.  Next, the free edge of said one channel wall is bent to form an outer ply around and overlapping the inner ply, with the abutted inner ply free edge and ledge serving as a support for the bending of the outer ply.  The adhesive is inserted between the plies when the outer ply is bent.

Patent CA-2044805-A1 (CA)
Inventor: SANO MASAMICHI
IPC: B22D1/00
Filed: 1991-06-17
Abstract: A melt is stored in a vessel.  A lower half of a degassing member is immersed in the melt.  The degassing member has a cylindrical form with the lower end closed, and the lower half section is made of a porous material which is permeable to gas and impermeable to melts as molten metal, molten slag, or molten matte.  This lower half section is a partitioning member.  When an internal space inside the degassing member is sucked to realize vacuum or reduced pressure atmosphere, gas producing components in the melt pass through the partition member of the degassing member, and are exhausted to inside the degassing member, thus being separated from the melt.          Also, by making the degassing member rotate or move in a horizontal or vertical direction, the melt is stirred.     With these features, gas-producing components in the melt can be removed at a high efficiency.

Title: Recycling apparatus for disintegrating discarded containers
Inventor: BARON KYLE L
IPC: B02C18/22
Filed: 1991-09-09
Abstract: Abstract of the Disclosure An apparatus, suitable for household use, for cutting and breaking empty discarded frangible containers into small pieces of material to facilitate subsequent processing and recycling of those materi-als.  The apparatus includes a manually operable load-ing bin for dumping containers (glass or plastic bot-tles and jars,  metal cans,  small cardboard boxes, etc.) into the wide upper inlet opening of a conical chamber.   Motor-driven  rotatable  circular  cutting blades,  having sharp edges which project into the chamber through slots in the chamber wall, cut and break the containers descending through the chamber into small pieces of material (glass, plastic, metal, cardboard, etc.).  The pieces exit the narrow lower outlet opening of the chamber into a selected one of several compartments in an adjustably positionable carousel below the outlet opening.   The slots (and blade edges projecting therethrough) are arranged in three radially spaced apart vertical columns around the chamber wall.  The slots in each column are verti-cally spaced apart.  The cutting blades in each column are rigidly mounted in vertically spaced apart, eccen-tric relationship on a drive shaft mounted exteriorly of the chamber.  One shaft is motor driven and drives the other two shafts through a pinion/ring gear mecha-nism.  Containers descending through the chamber are squeezed,  scored, cut and broken between the sharp edges of the cutting blades and the opposing cutting blades or opposing wall surfaces.

Abstract: ABSTRACT     A programmer for controlling the actuation and deactuation of a plurality of load function switches.  A motorized cam drum track moves a follower pivoted about a fulcrum pin.  A solenoid controlled by a microcomputer moves a slidably bar operable to selectively latch and unlatch the fulcrum pin.  When latched, the pin causes the follower to pivot and effect the actuation and deactuation of the associated switch in response to the cam track and the follower, when the fulcrum is unlatched, leaving the switch unmoved.  The solenoid controls latching and unlatching independently of the cam drum rotation.
