Title: Data integrity verification
Inventor: HELYER RICHARD MARTIN
IPC: G07D7/20
Filed: 1984-12-18
Abstract: Apparatus for verifying the integrity of data applied to a body, e.g. a cheque, from two sources has a strobe head 14a adapted to give an output signal when the presence of a strobe marker 12 is detected to initiate a reading of further data by read heads 14b to 14d.

Patent GB-2172802-A (GB)
Title: Apparatus for washing parts of human body
Inventor: ICHINO MASARU
IPC: E03D9/08
Filed: 1985-09-27
Abstract: The apparatus for washing parts of the human body is constructed by an external cylinder (1) attached to a toilet bowl (4), an intermediate cylinder (2) and a cylindrical nozzle (3) for spraying warm water. These three cylinders are telescopically received within each other. Between the external cylinder and the intermediate cylinder, a first coiled spring (6) is provided so as to be able to project and retract the intermediate cylinder from and into the external cylinder. Between the intermediate cylinder and the nozzle, a second coiled spring (7) is provided so as to be able to project and retract the nozzle from and into the intermediate cylinder. The nozzle has a loaded valve which is closed by a third coiled spring (8). When the pressure of the warm water is exerted upon the apparatus, the intermediate cylinder and the nozzle will project from the external cylinder against the resilient force of the first through third coiled springs, and when the pressure thereof is released, these cylinders are retracted to their initial positions in the external cylinder. The invention provides a shorter external cylinder than is usual and avoids exposure of the conduit to corrosion. <IMAGE>

Title: Mounting heated-resistor fluid-flow measuring sensors
Inventor: OHTA MINORU
IPC: G01F1/68
Filed: 1986-02-17
Abstract: A heated-resistor fluid-flow sensor comprises a film resistance pattern 82a, e.g. of Pt, Ni, or Ni-Cr deposited on at least one surface of a substrate 81 made of material, such as glass or ceramic, having a poor thermal conductivity which is supported at one or both ends by a member 14a, 14b made of a material having a thermal conductivity at least 10 times greater than that of the substrate, e.g. materials such as copper or aluminium, whereby heat generated in the resistance pattern 82a is efficiently diverted by conduction away from the sensor to the fluid flow rather than to a duct, such as the air intake of an i.c. engine, in which the sensor is mounted. The desired dissipation of heat may be further assisted by apertures 15 a, 15b in the supporting members, by portions of reduced cross-section or by mounting the supporting members 14a, 14 b on good thermal insulators, such as polyimide. The resistance film 82a is connected to an unheated resistor in a conventional bridge circuit which is arranged to maintain a constant temperature difference between the sensing and unheated resistors, the current supplied to the sensing resitor to achieve this being converted to a fluid-flow representative voltage which can be used to control fuel injection or ignition in the i.c. engine. <IMAGE>

Title: Control method for a direct-coupling mechanism for a torque converter or fluid coupling of an automatic vehicle transmission
Inventor: NISHIKAWA MASAO
IPC: F16H59/16
Filed: 1986-06-13
Abstract: A method of controlling a direct-coupling mechanism of hydraulic power transmission device of an automatic transmission for an automotive vehicle, wherein the transmission capacity of the direct-coupling mechanism is controlled such that the valve of a predetermined parameter indicative of an amount of relative slip between input and output members of the hydraulic power transmission device which are mechanically engaged with each other by the direct-coupling mechanism lies within a predetermined reference range. The predetermined parameter value is detected and the detected value is compared with the predetermined reference range. A desired value of the predetermined reference range and a predetermined period of time are determined on the basis of the comparison result. The transmission capacity is controlled to the determined desired value for the determined predetermined period of time. The transmission capacity is maintained so long as the detected predetermined parameter value lies within the predetermined reference range. At least first and second transmission capacity increasing regions are provided which correspond to larger values of the amount of relative slip than that the predetermined reference range corresponds to, wherein the first region is closer to the predetermined reference range than the second region is. A rate of increase of the transmission capacity in the first region is set to a value smaller than that in the second region. A fine-control region is provided adjacent at least one of extreme limits of the predetermined reference range, wherein the transmission capacity is finely adjusted toward the predetermined reference range.

IPC: H01H43/02
Filed: 1987-11-16
Abstract: The present invention provides a magnetron power control switch assembly for a microwave oven, comprising: a timer switch (2) providing a selectively variable period for which power may be applied to the magnetron, an ON/OFF micro switch (15) which, during the said period, when switched ON connects a power supply to the magnetron and disconnects the power supply when switched OFF, an actuating mechanism (2a) arranged to provide repeated ON/OFF switching of the ON/OFF switch (15), and manual control means enabling the ON/OFF switch (15) to be continuously switched ON independently of operation of the actuating mechanism (2a). Manual control (9) rotates a cam within a shied (11) to move a slide (14) from a lower position in which it holds the microswitch (15) in a permanently ON condition as shown, to an upper position. In the latter, rotating cogs and cam of the timer switch (2) vertically oscillate a finger (2a) to repeatedly switch the microswitch ON and OFF via lever (16). In the former position, the finger (2a) still oscillates but is ineffective, as lever (16) is permanently held down by slide (14). <IMAGE>

Title: Heart valve with disc occluder
Inventor: MARTIN RICHARD L
IPC: A61F2/24
Filed: 1989-11-22
Abstract: A heart valve prosthesis (10) which is suited for replacement of the aortic valve or mitral heart valve or any of the four valves in the heart. The invention includes a ring body portion (30) having a fluid flow bore (32) with an elliptical inner wall through which blood flows controlled by a disc occluder (44) supported between proximal and distal support struts (50, 52) having their ends attached to the metallic ring and coinciding with the curvature of the disc. The disc has a thickened outer edge (42) so that the disc allows blood flow through the opening in the ring by rotation and translation of the disc occluder, from a closed position in sealing engagement (35) around the ring body, to an open position wherein the thickened edge of the disc occluder (44) serves as a travel stop for translational movement of the occluder during operation.
