Patent CA-2015449-A1 (CA)
IPC: E05F3/14
Filed: 1990-04-25
Abstract: According to the invention, there is provided a damper for a flapdoor that does not show any damping effect when its movable shaft of the damper is rotated with the door in one sense whereas it effectively damps the rotary movement of the flapdoor when the movable shaft is rotated with the door in the other sense, wherein a one-way clutch for engaging or disengaging said movable shaft with a movable member depending on the sense of rotation of the movable shaft to cause a viscous shearing drag in the viscous fluid contained in the damper and a power source constitute so many integral parts of a coil spring.  A damper for a flapdoor having such an arrange-ment can have a simplified configuration as compared with a damper provided with a separate coil spring as power source and a separate one-way clutch and therefore can be realized with reduced dimensions.  Moreover, since such a one-way clutch can be prepared from a coil spring without requiring any additional processes and by simply engaging a portion of the coil spring with the movable member, the rest of the coil spring functioning as power source, the damper can be realized at a significantly reduced cost.

Abstract: MULTI-FUEL ENGINE CONTROL WITH FUEL CONTROL PARAMETER LOCK            Abstract of the Disclosure A fuel control for an engine using a liquid mixture of two fuels such as gasoline and methanol and derives a fuel control parameter from the output of a fuel composition sensor in a first mode of engine operation and locks the value of the fuel control parameter at the end of the first mode of engine operation for use throughout a second mode of engine operation including closed loop control in response to an air/fuel ratio sensor, as long as the fuel composition does not change more than a predetermined amount during the second mode.  The stable operation of the fuel control in the second mode is thus protected from instabilities introduced by small fluctuations in the fuel composition signal.  In an engine with adaptive learning control, the adaptive learning control mode is reserved for particularly stable modes of engine operation including closed loop stoichiometric control and thus serves well as the second mode of engine operation.

Abstract: The paper pressing arrangement comprises a paper guide plate for guiding a sheet of paper around a platen roller towards the typing line. The paper guide plate comprises two conveyor modules each of which supports three paper pressing rollers and is provided with a pivot element projecting from the barycentre of the triangle joining the midpoints of the three rollers. A control mechanism, in an operative position, transmits by means of a rocker lever pivotally connected to the pivot elements the action of a spring to urge the conveyor modules against the roller. The control mechanism comprises a lever for positioning the two conveyor modules in an inoperative position to permit insertion of the sheet of paper.      Each conveyor module defines a first axis for rotation of two front paper pressing rollers and a second axis spaced from the first axis for rotation of a rear roller disposed intermediate each pair front rollers. The paper pressing rollers have a rotary shaft of plastics material and a covering of rubber. Each conveyor module comprises, for each paper pressing roller two depressed seats for accommodating the shaft without force, and a through slot positioned between the two depressed seats. The through slot is of a width which is slightly less than the diameter of the paper pressing roller so that, in mounting, the rubber covering on each roller has to be slightly forced into the slot to permit the ends of the shaft to reach the seats. Each paper pressing roller then remains restrained between the two seats and the respective slot and will be capable of slight axial and radial movements until it is positioned against the platen roller.

Abstract: COORDINATION METHOD FOR MULTI-USER      SYSTEM CONFORMANCE TESTING          Abstract Coordination of test sequences to be run simultaneously by individual testers for conformance testing of multi-user systems to their specification is achieved in accordance with the present method. In order to utilize the present invention, it is necessary to generate a test sequence, desirably, one of minimum cost, which covers all aspects of the specification for the multi-user system under test. For many standard test sequence generation techniques, it is preferable torepresent the multi-user system as a finite state machine. The test sequence is then divided into several different test sequences corresponding to individual testers wherein each of the different test sequences can be run simultaneously by individual testers. Then, the separate test sequences are inspected to identify instances where coordination is required among the various multiple testers which are expected to run the tests simultaneously. After the coordination instances are identified, additional instructions coordination primitives are inserted into the original test sequence for each tester to permit effective coordination between all testers. coordintion signalling is performed on an out-of-band communication media between the testers.
