IPC: F16D57/02
Filed: 1990-07-11
Abstract: HYDRAULIC RETARDER AND CONTROL            Abstract of the Disclosure A hydraulic retarder and control composed of an accumulator, for rapid filling of the retarder; a pulse valve, for controlling fluid flow to and from the accumulator; a regulator valve, for limiting the inlet pressure to the retarder; and a pair of check valves, for preventing fluid flow from the retarder to a pressure source and from the retarder to the accumulator.  The pulse valve is controllable to provide rapid filling of the retarder, while the regulator valve will direct fluid from a secondary source to the retarder and control the pressure at the retarder inlet.  The accumulator is filled from the main pressure source, between retard requests, at a rate that does not disturb the main transmission pressure level.  One of the check valves and the pulse valve prevent the fluid in the accumulator from returning to the system other than when a retard request is present.

Patent CA-2022586-A1 (CA)
IPC: G06F12/06
Filed: 1990-08-02
Abstract: A scan converter control circuit includes first and second memories, each having a data write mode and a data read mode which are selected in response to a switching signal so that the first memory is in the data write mode when the second memory is in the data read mode and the first memory is in the data read mode when the second memory is in the data write mode.  A write address counter generates a write address which is to be alternately supplied to the first and second memories and generates a write completion signal when the write address becomes equal to a predetermined count value.  A read address counter generates a read address which is to be alternately supplied to the first and second memories and generates a read completion signal when the read address becomes equal to a predetermined count value.  A data input controller enables the write address counter in response to a data input signal supplied from an external circuit and disables the write address counter when receiving the write completion signal.  A memory switching controller generates the switching signal having a logic value which is changed in response to the write completion signal.  A data output controller enables the read address counter in response to the write completion signal and disables the read address counter in response to the read completion signal.

Title: Panel attached independant height adjustable corner terminal table
Inventor: BINGLEY BARRY
IPC: A47B9/12
Filed: 1990-11-29
Abstract: ABSTRACT      In a corner worksurface for supporting computer display terminals, it is known that said surfaces may be attached to panels at various height locations and may be disengaged from said panel(s) and reassembled at alternate height(s).  In this invention height adjustability may be attained without the need to disengage worksurface(s) from panels and thereby not affecting the height of supported surface.  The attached surface may have a secondary Independant Height Adjustable Surface housed within its structure to support the display terminal, and by means of a Mechanically Height Adjustable feature be raised or lowered as required to view the display terminal at a proper viewing height.  Because the height of the attached surface need not be altered, any adjacent worksurface(s) can remain at the same height creating a consistent height of worksurface(s) throughout work-station configuration.

Title: Rigid grating mat with unidirectional elements
Inventor: BEDICS MICHAEL A
IPC: E04C2/42
Filed: 1990-12-18
Abstract: A grating mat assembly is disclosed, which is of a generally rigid construction, as distinguished from an articulated, roll-up construction. Unlike conventional rigid grating mats, the structure of the present invention comprises a plurality of slot-like sections joined edge to edge in a manner providing for sufficiently rigidity for manufacture, handling and installation, while eliminating the customary longitudinally extending locking bars, utilized in more conventional grating mat assemblies, which add significantly to the cost of manufacture thereof. The slot-like mat sections of the new design are of extruded construction, formed with a horizontal upper ball, widely spaced vertical end walls, and one or more intermediate vertical walls. The vertical walls support the upper wall substantially above a base surface. The opposite vertical end walls of the slot-like sections are formed with tongue and groove structures, such that a pair of adjacent sections interfit to provide positive horizontal alignment. Adjacent slot-like sections are secured tightly together either by way of the tongue and groove structure, or by separate means.

Inventor: LAPCEVIC THOMAS G
IPC: A63B21/00
Filed: 1991-01-11
Abstract: ABSTRACT OF THE DISCLOSURE        The present invention provides a variable resistance exercise device which enables a user to select from an almost limitless set of resistance curves having various shapes and amplitudes.  These results are achieved using a baseline fixed resistance and a variable resistance generated by a torque arm assembly. Preferably, the torque arm assembly has a vertical diametric torque arm and two horizontal radial torque arms which are perpendicular to the vertical torque arm.  By varying the position of a weight member on each of these arms, as well as the ratio of the net horizontal torque and the vertical torque generated by the weight members, the resistance curve that the user experiences can be infinitely varied.  Additionally, through the use of a gear assembly, the user can achieve a force variance during the exercise which is greater than the minimum force experienced during the exercise.

Title: Improved composite cap including tamper indicating band
Inventor: MARSHALL F PAUL
IPC: B65D41/34
Filed: 1991-02-14
Abstract: This relates to an improved tamper band construction for use in conjunction with closure caps for locking beneath a retaining bead on a container neck finish when the closure cap is removed to indicate rotation of the closure cap. The tamper indicating band is provided with a plurality of flaps which are initially molded in a radially inwardly, axial downwardly directed position and then are folded upwardly to radially inwardly and axially upwardly directed positions where they are engagable beneath a container retaining bead. Most particularly, the plurality of flaps are joined in groups by connecting bridges so that each group of flaps pivot as a unit will the connecting bridges stretching and providing an over center snapping action to retain the flaps in their operative positions after they are folded to such positions. By providing a plurality of individual flaps which are joined together only by the relatively narrow connecting bridges, washing of the container beneath the closure cap to remove excess product is facilitated.

Patent CA-2038473-A1 (CA)
Inventor: ONODA MASAHIRO
IPC: H04L1/20
Filed: 1991-03-18
Abstract: In a mobile radio communication system, a mobile station constantly monitors a quality of a radio line between the mobile station and a first base station with which the mobile station is presently communicating, detects a deterioration of the quality of the radio line between the mobile station and the first base station outside a tolerable range, successively detects field intensities of signals received from the base stations neighboring the first base station using a free time slot which is unused by the mobile station for communication to determine a maximum field intensity, supplies to the first base station predetermined information related to a second base station from which the signal with the maximum field intensity is received so as to make a handover request, and ends a communication with the first base station in response to a handover message.  The first base station supplies a handover request message to a control station in response to the handover request from the mobile station, and the control station carries out a handover process in response to the handover request message. The handover process includes selecting a new communication channel with which the mobile station is to communicate with the second base station when the mobile station moves from a first radio zone to a second radio zone, and notifying the handover message and the new communication channel to the mobile station and the first and second base stations, so that the mobile station ends the communication with the first base station in response to the handover message and starts a communication with the second base station using the new communication channel.
