Patent GB-2150048-A (GB)
Title: Pulsator device
Inventor: CROSS DONALD JAMES
IPC: B03B5/04
Filed: 1983-10-14
Abstract: An electro-magnetic pulsator device (1), for use in material treatment apparatus such as a mineral jig, shaking table or vibratory screen, comprises an actuating spindle (2) which is slidingly received in a housing (6, 7, 8) and which is operatively coupled to an oscillatable member of the apparatus. The spindle (2) is given a pulsating action for vibration of the member by electromagnetic means (4, 5) which includes magnetic disc blocks (4, 5) spaced apart by a distance greater than the required pulsation amplitude. A radial metal reaction disc (3) attached to the spindle (2) is located in the space between the magnetic blocks (45) and serves to transmit the electromagnetic pulsation forces to the spindle (2). Electrical control means controlling the magnetic currents serves to control the spindle pulsation. The pulsator device provides a smooth and quiet operation, with readily controllable pulsation. <IMAGE>
Patent GB-2148751-A (GB)
Title: Manufacture of magnetic cores
Inventor: GIBBS MICHAEL RICHARD JOHN
IPC: H01F41/02
Filed: 1983-10-31
Abstract: A magnetic core is made by winding a length of amorphous strip of ferromagnetic material onto a mandrel. Simultaneously heating current is passed through a portion of the strip that is approaching the mandrel in order to heat-treat it and so modify the magnetic properties obtained. In this way the advantages of a very rapid annealing step can be achieved without the complications of pulse current techniques, and the material reaching the winding point may be hot enough to ensure stress relief. Induction heating may be used, or electrode heating applied. Here two spaced adjustable sliding contact electrodes or one electrode and the mandrel are utilised.

Title: Electronic typewriter
Inventor: GUBAU GIUSEPPE
IPC: B41J1/30
Filed: 1983-12-12
Abstract: The daisy wheel of an electronic typewriter is positioned by a stepping motor driven clockwise and anticlockwise by pulses passed through gates 228 and 229 respectively. Keyboard data on lines 163 is converted to a digital representation of desired angular position by a converter 200 and decoder 208. A counter 206 counting tachometer pulses provides a representation of actual position. A subtractor 211 and complementing logic 208 provide a position error signal on lines 214. A counter 219 counts clock pulses between successive position codes from the daisy wheel and a look-up table converter 218 provides a digital speed signal on lines 221. The difference between the position error and speed codes is formed by a subtractor 238 which controls a pulse width modulator 240 supplying pulses to the gates 228 and 229, whereby the power to the stepping motor is increased the larger the position error of the daisy wheel. <IMAGE>

Title: A process for dewatering a coal slurry
Inventor: SLACK DAVID JAMES IAN
IPC: F26B5/12
Filed: 1984-06-19
Abstract: Dewatering of coal slurry is improved by heating the slurry by passage through heat exchangers (15, 16) to 60 DEG C before feeding it to disc, belt or drum-type vacuum filter (11). The slurry is initially heated in heat exchanger (15) fed by hot filtrate from filter (11), and then in heat exchanger (16) by e.g. steam from line (17). Heating reduces the surface tension to produce a drier filter cake.

Title: Skipping rope
Inventor: MILLER ROBERT A
IPC: A63B5/20
Filed: 1985-01-24
Abstract: The rope includes resiliently flexible handles one at each end of the rope, for altering the moment of force imposed upon the user by the swinging rope.

Title: Fault avoidance in semiconductor memories
Inventor: SANDER WENDELL B
IPC: G11C29/00
Filed: 1985-08-01
Abstract: Semiconductor memories employing shared row and column input lines and having faulty memory cells or sense amplifiers are usable at their normal speed and without delay losses with the circuitry of the invention which separates input row and column addresses, and transmits the row addresses through a gated buffer (52) to the shared input lines (A0-A8) of the memory during the first state of a gating signal for use during a row enable signal. The circuitry includes a column address changing PROM (54) which has been programmed to skip addresses of columns having faulty cells or sense amplifiers and redirect the addresses to good columns. The PROM completes its address translations during the first state of the gating signal and transfers the corrected column addresses to the shared input lines during the second state of the gating signal for use during a column enable signal. <IMAGE>

Title: Reflected light surface roughness analyser
Inventor: HONDA YOSHIZO
IPC: G01B11/30
Filed: 1986-06-27
Abstract: A surface roughness analyzer directs a beam of light from a source (1) to an object (4) whose surface roughness is to be measured. A modulator (5) modulates a light source (1) with a modulating frequency. Mirror reflected light is detected by a detector (2) and scattered light by a detector (3). Filters (6, 7) are connected to the outputs of the respective detectors (2, 3) to take out only the component of light at the modulating frequency. The outputs from the filters (6, 7) are not affected by the influence of incoming light other than light from the source (1) and the surface roughness of the object (4) can be accurately measured. Other embodiments describe quadrant detectors to assist in monitoring correct alignment of the apparatus, surface and arrangement in which the scattered light is collected over an annular volume so that the result is not sensitive to directional irregularities on the surface.   <IMAGE>
