Patent GB-2238845-A (GB)
Title: Adjustable couplings
Inventor: IMURA YOSHIHITO
IPC: B62D5/083
Filed: 1990-10-16
Abstract: A power steering device comprising an input shaft 1 connected to a steering shaft, an output shaft 2 connected to a rack for driving vehicle wheels, a servo valve 9 including a valve sleeve 3 surrounding the input shaft and engaging the output shaft, and a torsion bar 4 with both ends secured to the input shaft and the output shaft. In the power steering device, the torsion bar 4 is positioned and secured via a balance pin 6 in the input shaft 1. The balance pin 6 has multiple projecting portions arranged alternately on opposite sides of the balance pin along the length of the balance pin. After inserting the balance pin 6 into the input shaft 1 and the torsion bar 4, the input shaft and the torsion bar are relatively rotated by the protruding portions of the balance pin. A servo valve is thus correctly centered. The hydraulic pressure produced by the servo valve is balanced. <IMAGE>
Patent GB-904617-A (GB)
Abstract: 904,617. Ignition systems. TUNG-SOL ELECTRIC Inc. March 1, 1961 [March 7, 1960], No. 7533/61. Class 7(4) An ignition system has means connected or adapted to be connected to a source of direct current for creating a series of current pulses synchronized with the movement of the engines pistons, a current amplifier for amplifying pulses created by the said means, an inductor or transformer coupled to the output circuit of the amplifier a capacitor coupled to the inductor or transformer for receiving a charge therefrom and a discharge circuit which includes the capacitor a switching device and an input winding of an output transformer the output transformer having a winding coupled to the spark plugs. In Fig. 1 the breaker contacts 11 are operated by mechanical gearing coupled to the engine shaft. When the contacts 11 are opened the current through the transistor output circuit is cut off abruptly and the collapse of the magnetic field sets up a voltage in the secondary winding 18 which results in a charging current through rectifier 38 capacitor 21 and the winding 24. This current charges the capacitor 21 to a potential of approximately 2000 volts. When contacts 11 are again closed a positive voltage pulse is applied to the firing electrode 32 by winding 20 and discharge device 23 is made conductive discharging the capacitor 21 through the discharge device and the primary winding 24 of the output transformer. In a modification a crystal diode is substituted for the rectifier tube 38 and the transistor is of the NPN type. During starting conditions the arm of the switch 58 is placed in engagement with a contact 59. In other modifications there are two transistors in circuit with the primary winding. The discharge device 23 has its firing electrode energized by the secondary winding of a transformer whose primary winding is connected in series with the battery 10 and contacts 11. In Fig. 7 a modified primary circuit is employed including a transistor 65 and an NPN transistor 67 is employed in place of the discharge device 23. The output transformer is an auto-transformer 71. Use of a semi-conductor type thyratron for example a silicon controlled rectifier is referred to.

A method of making a door support housing comprising a body portion having pairs of side and end walls, an open guide-way on one side and external mounting flanges projecting in opposite directions about the guideway, comprises providing a strip of end connected metal housing blanks having lugs projecting from each side, bending the lugs of the lead blank at 90 degrees to form the housing end walls, confining the end portions in a die to form mounting flanges and bending the intermediate portions of the blank along parallel transverse lines to cause the sections to close towards each other to form opposed side walls and then severing the housing from the strip. A strip 61 of interconnected blanks 60 having lugs 37, 38, tabs 40, 41, holes 66, 70 and partially sheared nib projections 71 is fed through a progressive forming tool 63. Prior to passing through the die 63 the tabs 40, 41 are deflected through 90 degrees along bend lines 72. The blank 60b is held on a guide rib 85 by a spring-loaded stripper plate 81 and a fork-ended punch 79 engages and deflects the lugs 37, 38 downwardly alongside the side faces of the rib 85. In a second operation the blank 60 and the end piece 94 are sheared from the portion 25a by a punch 80 which holds the blank on the spring- loaded pressure plate 99 and the guideway portion formed by bending the blank along the lines 67, 68 over a fixed mandrel 97 into a recess 101 to cause the tabs 40, 41 to overlap the lugs 37, 38. The punch 80 is provided with a spring-loaded ejection plunger 106. The tabs 40, 41 are subsequently welded to the lugs 37, 38 at a point 43. A wedge 27 and a spring 49 are assembled with a rod 44 to a housing 25 to make a door support. Specification 916,754 is referred to.

Title: Monitoring operation of tap changing power transformer
Inventor: HISCOCK NICHOLAS JOHN
IPC: H02J3/00
Filed: 1992-05-27
Abstract: A monitoring device prevents the voltage applied to an electrical distribution network reaching unacceptable levels if a system in use to operate regulating tap changing equipment attached to a power transformer operates without correct initiating signals from the control system. Any action of the regulating equipment must be preceded by a control signal to initiate the action. The device monitors a tap changing initiation signal 111, and changes in a signal 105 representing the actual tap position.

Title: Non-coherent cache refresh mechanism.
Inventor: JARVIS NEIL ALASDAIR JAMES
IPC: G06F12/12
Filed: 1992-10-01
Abstract: A cache memory refreshment mechanism employing ageing-out criteria to remove stale entries from the cache memory, Entries in the cache memory may have one of four states: 1) VALID, indicating that the entry may be used by the local processor; 2) DYING, indicating that the entry may be used, but that it has been in existence in the cache for a predetermined period of time; 3) REFRESH, following a dying status, indicating a) that the entry may still be used, b) that the entry has just been used while in the dying state, and c) that retrieval of data to update the entry and return it to its valid state is being effected; and 4) IDLE, indicating that the entry has been aged out of the cache, and may not be used. The refresh status enables a cache entry to be updated independently of the processor, and thus the number of processor stalls resulting from data not being available in the cache after having been aged out is reduced. <IMAGE>

Title: Controlling a plurality of devices
Inventor: MAGILL SHAUN
IPC: H04Q9/14
Filed: 1993-10-04
Abstract: Apparatus for controlling a plurality of dampers in an air conditioning system comprises a plurality of damper control stations (7) connected in a serial network loop (10) controlled by a network controller (15). Initially the network controller (15) transmits a global poll message around the network loop through the station controllers (7) each of which attaches its address to the message so the global poll message received by the network controller comprises the station addresses in the sequence in which the station controllers are connected in the network (10). A break in the loop and its location are detected by transmitting a global poll message. Each controller acknowledges receipt of the message to the preceding controller. If this does not receive the acknowledgement it sends the message back to the network controller (15) which then sends a global poll message the other way round the loop. A station controller (7) can be by-passed and operate under its own local control. <IMAGE>
