Patent GB-941917-A (GB)
Abstract: 941,917. Axle counting systems. STANDARD ELEKTRIK LORENZ A.G. March 24, 1961 [March 25, 1960; May 5, 1960], No. 10885/61. Heading B7N. [Also in Division G4] In an arrangement for counting axles into and out of a railway section, each axle generates an impulse which sets up a direction-dependent storage device and at the same time is applied positively or negatively to a counter dependent on direction of movement, the counter then sending an impulse to restore the storage device. Failure brings up an alarm. Axles can be counted in or out at both positions I and II, the direction of movement being determined by the order at which impulses are generated at A1, B1 and A2, B2. The signals are analysed at J1, J2 and pass through an intermediate store T to a counter AZ which thus indicates the number of axles in the section. Each signal from position I or II is likewise fed to J11 or J12 to set up the associated supervisory device Sa or Sb but this is restored at each addition or subtraction from the counter AZ. If Sa or Sb remains operated for a predetermined time an alarm is operated by relay D. Step output from counter AZ. The counter AZ is a known type of binary cascade counter with 9 stages arranged in three groups of three. Each stage has a resistor output so that each group can supply any one of 8 different potentials to its associated output lead 1, 2 or 3, Fig. 4. A step in potential on any one or more of these leads is differentiated and amplified to produce a " return pulse " on lead 4. Detection of incoming and outgoing axles, Fig. 3. An impulse from B1 is converted by a threshold switch Tr3, Tr4 into a rectangular impulse which is applied to the emitter of transistors Tr5, Tr6. An impulse from A1 is likewise converted by Tr1, Tr2 and differentiated by L4 before being applied either with the same or inverted polarity to the base of Tr5 or Tr6, respectively, according to whether it follows or precedes the impulse from B 1. Accordingly an "in" or an " out " pulse appears on terminals e11 e12 or a11, a12, respectively, by reversing the transistor pair Tr9, Tr10 or Tr7, Tr8. The operated transistor pair is restored by an " interrogating " pulse on lead a2. Supervisory circuit, Fig. 5. Impulses from position I are applied to threshold switches Tr19, Tr20 and Tr21, Tr22 as in the case of Fig. 3. However, in this case Tr23 conducts only at the detection of an incoming axle to change over transistor pair Tr24, Tr25. A " return pulse " on lead 4 from counter AZ restores the transistor pair. Otherwise, after a delay of 10 m. sees., Tr26 conducts to mark lead 5 and energize the alarm circuit (Fig. 6, not shown). If the capacity of the counter AZ is exceeded the absence of a " return pulse " causes operation of the alarm. The alarm circuit may also operate if the voltages at various points in the apparatus are incorrect.

Title: Liquid crystal display
Inventor: OCHI ISAO
IPC: G09G3/36
Filed: 1995-01-24
Abstract: A liquid crystal display capable of removing D.C. voltage applied to a liquid crystal panel when halftone images are formed by dithering. In a halftone liquid crystal display operated by switching a plurality of sets of reference voltages in an A/D converter for dithering, a phase control signal (20) is provided for controlling the phase of dithering, and a set of reference voltages selected for one polarity of a liquid crystal driving voltage can be switched to other set of reference voltages by changing the logical value of the phase control signal (20). The D.C. voltage applied to the liquid crystal panel is offset by the voltage difference between the polarities of the liquid crystal driving voltage that occurs when data is converted to another data different by one gradation by dithering. The burn on the liquid crystal screen is thus reduced. <IMAGE>

Title: Automatically adjusting clutch
Inventor: YOUNG ALASTAIR JOHN
IPC: F16D13/75
Filed: 1996-09-14
Abstract: An automatically adjusting clutch including a pressure plate 213. The pressure plate has a first part 230 adjacent a driven plate 215 and a second part 240 situated in the force bias path between a clutch engaging spring 212 and the first part when the clutch is engaged. The first part is limited in its disengagement movement by a stop ring 271, and the second part moves axially relative to the first part to adjust the effective thickness of the pressure plate. During disengagement of the clutch following wear of the facings, the effective axial thickness of the pressure plate 213 is increased and subsequently during re-engagement of the clutch the stop ring is adjusted to ensure the disengagement movement of the first part remains substantially constant throughout the life of the clutch. The second part 240 and the stop ring may each rotate relative to the first part 230. The automatically adjusting clutch may have resilient retraction means 214 which assist in moving the first part away from the flywheel during clutch disengagement and when the first part reaches the limit of its movement the load of the resilient retraction means is reacted by the stop ring 271.

Title: Printing on a surface of an elastic plastics material, especially a PVC based computer mouse mat, involving firstly screen printing then transfer printing
Inventor: ALLEN ARTHUR
IPC: B41M5/50
Filed: 1997-01-06
Abstract: There is disclosed a method of printing on a surface of an elastic plastics material, comprising: screen printing a background ink or varnish; and transfer printing a colour image and/or text over the background ink or varnish. Preferably, the ink or varnish is continuous. This allows a customary coverseal to be dispensed with. In an alternative which uses less ink or varnish, that is printed in an array of dots. This method is particularly suitable for the printing of computer mouse mats, eg with promotional material, since (1) Screen printing is limited to the application of blocks of solid colour, it not being possible to produce graded photograph-like colour images; and (2) experiments have been conducted with printing the base layer of a mouse mat by transfer printing using a colour copier but a adhesion of the transfer ink to the base layer is not good, especially if the layer is stretched.

Abstract: 976, 517. Gyroscopic apparatus. LITTON INDUSTRIES Inc. Feb. 18, 1963 [Feb. 19, 1962], No. 6399/63. Heading G1C. A gyroscopic assembly has undesirable torque resulting from mass unbalance counteracted by applying a torquing signal to the gyro torquer representative of accelerations experienced by the gyroscope. As applied to an inertial guidance system 10, the accelerometers 30, 31, 32 which are already provided are used also to supply signals to networks 40a, 40b, conveniently arranged on the casings 12,13 of the particular gyroscope with which they are associated, the networks 40a, 40b having resistances of such values that the currents passed from the networks to the torquers of the associated gyroscopes cause torques to be applied to the gyroscopes which balance the error torques caused by acceleration acting on the mass unbalance of the gyros. To facilitate the provision of correct resistances the centre of gravity is arranged to be nearer the intersection of the three axes than the centre of buoyancy. Specifications 885,303 and 924,093 are referred to.
