Patent CA-2076103-A1 (CA)
Title: Sealed lever latch
Inventor: GROMOTKA GABRIEL
IPC: E05B63/06
Filed: 1992-08-13
Abstract: The present invention provides a sealed lever latch for securing a door panel of a cabinet or the like in a closed position relative to the frame.  The sealed lever latch is installed within an aperture formed in the door, and releasably retains the door against the frame when the door and the frame are latched together.  The sealed lever latch includes a housing for mounting in the door, a handle assembly which is pivotally attached to the housing, and rotatable between an opened and closed position, and a fastening means.  The fastening means retains the door, when the door is closed against the frame, by engaging the frame as the handle assembly is rotated to the closed position.  The housing, handle assembly and fastening means form a integral solid structure for preventing the passage of matter through the latch itself. The sealed lever latch further includes a biasing means which is adapted to retain the handle assembly in the closed position, and urge the handle assembly from the closed position to the opened position upon disengagement.  A trigger means is also included for latching the handle assembly in the closed position, and unlatching the handle assembly from the closed position for movement to the opened position.  The trigger means which is integrally disposed within the central vicinity of the handle assembly provides increased mechanical advantage during the closing thereof.

Abstract: An exemplary frame for carrying two or more tiers of vehicles within a standard cargo-carrying container includes frame-supporting wheels rotatably supported in interposed relation between the sides of the lower rail of the frame for streamlined operation. Installing structure included on the upper and lower rail of the frame, such as an upper and lower plate each having a toothed edge, enable selective coupling of a vertical post member to the upper and lower rails either in a first suspended position in which longitudinal movement along the respective rails is possible or in a second suspended position locked against such movement. The exemplary frame also includes a storage mechanism where each vehicle-supporting wheel cradle is pivotable about a load-bearing hanger for securement in a storage position extending parallel to the sides of the frame. Also included is a mechanism for limiting longitudinal movement of the frame inside a container, which includes a head selectively extensible in a direction longitudinal of the frame toward an interior margin of the container. Preferably the head also pivots transversely for engagement of the head with a respective side wall of the container so that, in conjunction with a like mechanism operating on a separate frame, the ends of a number of collapsed frames may be securely held in transversely clamped condition within a single container.

Title: Hearing aid
Inventor: PFANNENMUELLER GERHARD
IPC: H04R25/00
Filed: 1993-06-25
Abstract: ABSTRACT OF THE DISCLOSURE A hearing aid has a microphone, an amplifier, an earphone, and a battery as a source for an operating voltage. A switching amplifier is provided as an output stage. A delta voltage generator forms a base signal generator for a pulse-duration-modulated signal with which the switching amplifier can be controlled. The delta voltage generator comprises at least one integrator whose integration direction is reversible, dependent on an input signal thereto. A quotient of an operating voltage and a peak value of a delta voltage of the delta voltage generator remains at least largely constant given a changing operating voltage. For that purpose, the integrator is in an interactive connection with a switch at its input side and with a comparison circuit at its output side. The comparison circuit controls the switch by which the input signal can be supplied to the integrator, dependent on at least one threshold voltage derived from the operating voltage.
Patent CA-2101071-A1 (CA)
Title: Transmission of multiple carrier signals in a nonlinear system
Inventor: POSNER RICHARD D
IPC: H04B14/02
Filed: 1992-01-29
Abstract: A narrow band complex input signal, typically having multiple independently modulated carriers, is processed to produce an output signal. The process separates the multiple input signals (10) into an amplitude-limited angle-modulated carrier component (14) and an envelope component (18), and then combines these components by a form of pulse-duty-factor modulation such as pulse-duration modulation (16), at a sufficiently high sampling rate. The combined signal is input to a nonlinear power amplifier (22). Unwanted sidebands are rejected by bandpass filtering (24) at the amplifier output so as to pass only the carrier and its signal bandwidth.

Title: Beam compensation methods for satellite communication system
Inventor: PATTERSON DAVID P
IPC: H04W16/24
Filed: 1992-11-06
Abstract: Beam Compensation Methods pertain to the management of radio beams (11) which are generated by a constellation of satellites (S).  These beams (11) are precisely controlled so that they illuminate ''Earth-fixed cells'' as opposed to ''satellite-fixed cells''.  In previous satellite communication schemes, spacecraft which are not held stationary over one particular location on the Earth in geo-synchronous orbits fly over large regions of the Earth very rapidly. In a system that employs satellite-fixed cells, the ''footprint'' (10) of the radio beams (11) propagated by the spacecraft defines the zone on the ground called a ''cell'' which is illuminated by the spacecraft. This satellite-fixed cell moves constantly as the spacecraft moves around the globe. In sharp contrast, an ''Earth-fixed cell'' (14) is a stationary region mapped onto the surface of the Earth that has permanent fixed boundaries, just like a city or a state.
