Title: Improvements in or relating to the Reduction of Wheel Slip in Locomotives.
Inventor: HILL MICHAEL LEO GEORGE
IPC: B60L3/10
Filed: 1968-01-26
Abstract: 1,182,855. Control of motors. HAWKER SIDDELEY DYNAMICS Ltd. 27 Jan., 1969 [26 Jan., 1968], No. 4287/68. Heading H2J. In a system for reducing wheel slip in railway locomotives in which the energizing voltage is temporarily removed (from all motors) when slip is detected the rapid build-up of current consequent upon restoration of the voltage is checked at a value less than that which obtained when slip was detected, further increase occuring only at a slower rate. The object is to prevent the immediate recurrance of slip. The current in each motor M (there may be six), is detected by a magnetic dependent resistor 11 in a C-core 12 surrounding each bus-bar 14. The current signals are differentiated at 19 to provide rate of change signals which are combined and amplified at 20. If the rate of change exceeds a threshold value in a device 21 this is deemed to be due to wheel slip and an over-ride signal is applied to the regulator 17 of a diesel driven generator 15 to reduce its output to zero. The rate signal is also applied to a memory circuit 22 which comprises an integrating capacitor, the charge on which represents motor current, and when slip occurs this discharges at a predetermined rate. When slip has ceased the voltage is restored and the current rapidly increases to a value corresponding to the now reduced charge on the capacitor, and further increase occurs at a rate determined by the charging rate of the capacitor. The slip signal may also be applied to an engine regulator 18 to prevent undesired governor reset and the system may be combined with one in which motor currents are compared and a small reduction of current is made if this indicates " creep " or slip at high speed, but this arrangement is not described in detail.

Filed: 1969-01-25
Abstract: 1299871 Image reproduction EMI Ltd 26 Jan 1970 [25 Jan 1969] 4332/69 Heading H4F In an image reproduction arrangement in which it is required to reproduce images having no grey scale on a C.R.T., e.g. in photographic type composing apparatus, the video signal obtained for example by scanning an alphanumeric character with a flying spot scanner, is fed directly and via a delay device (e.g. one line or for interlaced scanning one field period delay) to an adding network before it is quantized. The delay is such that signal elements from corresponding positions in adjacent line scans of the image are superimposed. Preferably the delayed signals comprise only those which are too small to be passed by the quantizing device, i.e. they would be quantized to "0" by the quantizing device rather than "I". In this manner the parts of the images which straddle two line scans, as shown in Fig. 1, are not omitted as shown in Fig. 2 but are reproduced as shown in Fig. 4. In the type composing apparatus the characters are selected from a matrix and the resulting C.R.T. display is photographed (Fig. 5, not shown). Instead of a flying spot scanner a television camera may be employed.

D. ; 94, Kenilworth Drive, Akron, Ohio, U.S.A.) Feb. 19, 1932, No. 4979. Convention date, March 11, 1931. [Classes 70 and 87 (ii).] A collapsable former or core for wheel tyres comprises a pair of key sections and a pair of intermediate sections, all being fitted with racks engaging pinions having concurrent rotary movement, but adapted to move the key sections radially inwards first and then the two intermediate sections. The two key segments 35 are fitted with racks meshing with opposite sides of a pinion 20, while the remaining segments 44 carry racks engaged by mutilated pinions 21, 22 respectively. The application of a brake band 14 to the sleeve 12 while the assembled former is rotating, causes the link 47 to draw the one key section 35 downwards, thus causing a corresponding movement of the opposite section through rotation of the pinion 20. The same movement rotates the mutilated pinions 21, 22 so that they eventually gear with their respective racks to produce an inward movement of the remaining segments in timed relation to that of the first pair. On releasing the band brake the segments are restored to the acting position by centrifugal force. The untoothed portions of the mutilated pinions are formed as cam surfaces to bind against the rack bars and prevent movement of same when the gears are not in operation. A modified construction is described for use when the drum is rotated by hand.

Title: Apparatus for galvanizing the insides of pipes and similar hollow bodies
IPC: C25D7/04
Filed: 1929-02-14
Abstract: 328,709. Schl÷tter, M. Oct. 30, 1928, [Convention date]. Electrodes;connections; supporting electrodes; electrodes, moving; electrolytes, circulating.- In electroplating pipes internally by apparatus in which the pipe as the cathode is held vertically, and a flexible anode is passed through cap stoppers at both ends of the pipe so as to be centrally positioned, the anodes are kept taut by means of weights. Pipes 8 are pressed into clamps 6 on a cathode lead 5 which is carried on insulating supports 7. A spring cap stopper 10 of insulated material or provided with an insulating liner 9 is placed over the lower end of each pipe and is so arranged that on operating a lever thereon, the liner fits tightly against and seals the pipe. The top of each cap is closed by a cap 15 provided with a movable lateral discharge tube 16 spinning into a main 17. The electrolyte enters the pipes 8 through adjustable taps 11 on the stoppers 10 and completes its circuit through the caps 15, pipes 16, main 17, tank 18, pipe 19, pump 20, pipe 22, feed tank 14, and distributing pipe 12. An open channel underneath the lower platform allows the electrolyte to be run off into the tank 18 when the process has been completed. The anodes, normally in the form of wire, are wound on drums, and to insert an anode, the corresponding drum is released and the anode, kept taut by weights on its end, is drawn into the pipe over a set of rollers. It is guided centrally through the cap 15 and passes through a slotted stopper in the cap 10, and when freely suspended and taut with the weights outside the pipe. the slotted stopper is closed and the tap 11 opened. In the case of curved pipes, the anode is maintained in a central position by insulated spacing rings threaded upon it, and the slotted stopper presses elastically against the anode which is moved to and fro during the process.
