Title: Improvements relating to deceleration controllers
Inventor: HARRISON ANTHONY WILLIAM
IPC: B60T8/26
Filed: 1987-02-27
Abstract: The present invention provides a deceleration controller for a railway vehicle comprising a valve member (23) which is axially movable in a pressure chamber (1) in a body (3) between an open position and a closed position to control fluid flow between an inlet (33) and an outlet (25), a passage (19) connecting one part (7) of the chamber (1) which includes the outlet (23) with another part (21) of the chamber (1) located between said valve member (23) and a spring loaded piston (11). When the brake is applied the initial fluid flow through the controller takes up brake pad clearance. When the clearance is taken up pressure in chamber 7 rises rapidly and causes piston 11 to move to an equilibrium position. This increase in volume of chamber 21 causes a rapid fluid flow through passage 19 which causes a pressure drop across the valve member 9 which thus moves to the right. The angled surface 29 approaches valve seat 31 closing the controller and reducing the pressure rise in chamber 7. <IMAGE>

Title: Resistance welding apparatus
Inventor: BROWN ROBERT
IPC: B23K11/24
Filed: 1987-05-20
Abstract: Welding electrodes 2 are connected to the secondary winding 4 of a transformer 6 which has a primary winding 8 connected at one end to a neutral dine N of a three phase AC supply, the other end of the winding 8 being sequentially connected to the three phase liner R, Y, B via thyristor which are controlled so that the winding 8 is connected to one only of the phase liner R, Y, B at any time. Changeover from connection to one phase to connection in another phase is effected at a zero crossing of the remaining phase in each case, so that each welding current pulse has a duration of one sixth of an A.C. cycle (Fig. 2). The apparatus may be used to produce overlapping weld spots along the seam of a tinplate can. The welding current pulse duration is increased and decreased stepwise as respectively the leading and trailing end of the seam is approached to compensate for the decreased heat dissipation from the welding zone when near the seam ends, whereby the weld spots near the ends have a size comparable to the other weld spots. <IMAGE>

Patent GB-2236464-A (GB)
Title: Method and apparatus for non-linear dithering of digital images
Inventor: WELLS STUART C
IPC: H04N1/40
Filed: 1990-05-10
Abstract: The method and apparatus of the present invention takes into consideration that the eye is more sensitive to intensity variations at low levels of intensity than at high levels of intensity and produces higher quality dithered images by employing a sectioned or piecewise linear quantization strategy which sacrifices the fineness of interval spacing at the high end of the intensity scale in order to achieve greater accuracy of reproduction at the low end. The input intensity values are divided into a plurality of sub-ranges indicative of low, mid and high intensities. The number of input intensity levels allocated to the low intensity sub-ranges is small (eg 9) and the number of quantized or output intensity levels allocated to the low intensity sub-ranges is large compared to those allocated to the high intensity sub-ranges such that the interval spacing at the low intensity sub-ranges is small to provide greater accuracy at the low intensity levels where the eye is most sensitive.   <IMAGE>

Title: Master/slave field programmer
Inventor: SOERENSEN SOEREN
IPC: G06F9/445
Filed: 1992-01-31
Abstract: A master field programmer 10, 11 is used for programming selected functions into equipment 17 in the field, for example programming radios. In addition to storing a master program of all possible functions the master field programmer has means 19 for receiving and storing information defining a subset of those functions and means for irreversibly restricting its operation to that subset of functions, so as to operate as a slave programmer capable of programming into equipment functions selected from only the subset of functions. Whether the programmer operates as a master or slave is determined by comparing an actual measured size of the stored program and any subset defining information with a predetermined value. If the actual size value exceeds the predetermined value then the field programmer is storing data defining a subset of functions in addition to the master program and is accordingly restricted to operate as a slave programmer. <IMAGE>

Title: Method for transporting fluids.
Inventor: HARRISON DAVID
IPC: E21B43/01
Filed: 1992-02-21
Abstract: A method of transporting a fluid through a body of liquid involves the use of a collapsible hose 7. The fluid is initially compressed 2 to a pressure equal to or slightly above ambient and transported by the hose to a position of shallower depth. During transportation the pressure of the fluid is maintained equal to or slightly above the ambient while the hose rises in the liquid. The method is particularly suitable for the transportation of gas through seawater. For longer distances, the fluid is periodically recompressed and transported from a lower depth to a higher depth e.g. through hose (14). The hose can be laid along a rising seabed, Fig 2 (not shown). <IMAGE>
Patent GB-2255246-A (GB)
Title: Elevator system
Inventor: TAKAHASHI HIDEAKI
IPC: B66B5/02
Filed: 1992-03-13
Abstract: To obtain accurate data on the position of an elevator cage (1), in spite of power failure or vertical vibration of the cage, a serial absolute rotary encoder (SAE) (10) is rotated in accordance with the movement of the elevator cage (1). An output of the SAE (10) when the cage (1) is positioned at a reference floor is stored. When data on the position of the cage is necessary, the current output of the SAE (10) is read and the difference between the read output and the stored reference positional data is calculated. An uninterruptible power source having a capacity low enough only to back up a C-RAM suffices. The speed of the cage (1) is calculated from the output of a pulse encoder (11) and compared with a desired speed calculated from the calculated position data to control the torque of a driving motor (5).
