Title: Improvements in axminster looms
IPC: D03D39/02
Filed: 1963-12-19
Abstract: 1,038,202. Axminster looms. JAMES LEES & SONS CO. Dec. 19, 1963 [Dec. 20, 1962], No. 50208/63. Heading D1E. An Axminster carpet is woven with rows of long or short tufts and, if desired, some tufts of a row being omitted so that the tufts of adjacent rows "spread" to give sculptured areas. In a comb-type loom, Figs. 1-12, cam plate 70, revolving anti-clockwise at half loom speed, moves followers 97, 77, 105 and 92, in that order, the followers 105, 92 being nearer the rotational axis of cam 70 so that they have a greater throw. The followers 77 and 92 are both connected to a comb 75 which is therefore raised two different heights depending on which follower is actuated. The followers 97, 105 similarly raise a spool-dip stop rod 99 two different heights. In operation, the follower 97 has raised the rod 99 a small amount so that the spool 95 has dipped a relatively large amount into the warp and wiped in long tufts which are beaten up by a reed 115. The follower 77 then raises the tuft ends 120 a small amount, weft 125 is laid and beaten-up and knives 126, 127 operate to shear the tufts. The cam 70 then actuates follower 105 to raise rod 99 a relatively larger amount so that the spool 95 is prevented from dipping so far into the warp and smaller length tufts are inserted and beaten-up. The follower 92 then raises the comb 75 a relatively larger amount, Fig. 23 (not shown), so that a member 135 on the comb lifts the fabric from the race board 117 so that when the knives operate they cut shorter tufts. A reciprocating member 140, Fig. 23 (not shown), may clear the long tufts from the path of the knives and a stop 109 on the rod 99 may replace the follower mechanism 97 for the long tufts and various cam arrangements 70 may be used to give different arrangements of long and short rows. The invention is also described in application to a noseboard type Axminster loom.

Patent GB-1076519-A (GB)
Title: Process for preparing pastes containing metal powder
IPC: B22F3/22
Filed: 1964-12-16
Abstract: A paste comprising nickel powder suspended in a gel is prepared by dry mixing nickel powder and a powdered cellulose derivative capable of forming a gel with water, subjecting the resulting homogeneous mixture to a vacuum, and thereafter adding water to the mixture in vacuo to form the paste.  The cellulose derivative may be hydroxyethylcellulose or carboxymethylcellulose. The water may be degassed, for example by boiling, before being added to the dry powder mixture and also may be preheated to such a temperature that it boils when added to the mixture in vacuo.  As described and illustrated, the mixture of nickel powder and cellulose derivative may be placed in a pressuretight container which is evacuated before adding the water; the latter preferably is sucked into the container as a result of the reduced pressure therein. The powder mixture and water may be mechanically stirred, preferably under reduced pressure. By causing the mixing to take place with degassed water boiling under reduced pressure, a paste is given which is free of occluded air bubbles, which retains the original metal powder structure, and which is suitable for the preparation of a sintered electrode carrier for a storage cell.

Title: Apparatus for forming the product of two binary data word
IPC: G06F7/533
Filed: 1975-12-17
Abstract: 1523750 Multipliers WESTERN ELECTRIC CO Inc 17 Dec 1975 [20 Dec 1974] 51594/75 Heading G4A An n bit 2s complement product of an n bit and an m bit signed 2s complement word is calculated by forming the partial products of the data words, periodically truncating the least significant bit of some of the partial products and extending the truncated partial product by duplicating the sign bit thereof. As described the apparatus includes m cascaded stages and a 2s complementing stage, one bit of each of the m bit words being latched into a bistable, e.g. 308 in each stage and the sign bit being latched into bistable 318 of the 2s complemented. In each stage a partial product sequence B<SP>1</SP>, D, G, J is formed by adding the stored bit of the m word applied at input 302 with the successive bits of the n bit word applied at input 300, in each stage except the first, each of these bit products being summed (e.g. in summer 315) with the output bit of equal significance of the preceding stage. Truncation is effected by using, e.g. AND gate 311 receiving control signal r 0  delayed to produce control signal r 1 . Extension of the sign bit is effected by AND gate 312 causing the output, e.g. C of each stage to be reapplied to an associated storage bistable, e.g. 314. If the sign bit stored in bistable 318 is "1" indicating a negative word the output signal is 2s complemented to provide the required product at terminal 323.

Abstract: 1,150,169. Interruptions during break-spinning. SCHUBERT & SALZER MASCHINENFABRIK A.G. 14 Nov., 1967 [19 Nov., 1966], No. 51784/67. Heading D1D. Before feeding back a piece of yarn into the spinning chamber 2 of a break spinning device for restarting spinning, e.g. after interruption due to threa breakage, the yarn is separated at a predetermined point to provide a flawless thread end, and the separated off thread end is removed from the chamber by suction through tube 4. The separation may be effected by a mechanical or electrical cutting device 7 engaging through a slit 32 in the yarn outlettube and axially displaceable thereabout. Alternatively the separation is effected by allowing the spinning chamber to run on after the delivery and withdrawing devices have been stopped so that the yarn F is excessively twisted but the twisting is not communicated to the fibre ring R due to centrifugal force such that breakage of the thread occurs.

Suitable materials are silicon, germanium and gallium arsenide for the semi-conductor body and silica, silicon nitride and germanium dioxide for the optional insulating film. A preferred device based on a lohm. cm. N type silicon wafer 200Á thick comprising a 15-500 A silica layer and a layer of tin oxide 6Á thick is made as described in copending application 51836/72 up to completion of the tin oxide layer, which is then coated with nickel by vapour deposition. The oxide on the periphery of the wafer is then exposed by etching away the overlying nickel and tin oxide, and removed by treatment in 5% hydrofluoric acid. A natural oxide layer which reforms on the exposed surface may be reinforced. If the device is required to be light-sensitive an area of the nickel overlying the transparent tin oxide is removed. The reverse breakdown voltage of the interface increases with increasing humidity. In operation with the interface biased beyond its breakdown voltage the avalanche current decreases with increase in humidity.

Abstract: 1368811 Colour television RCA CORPORATION 11 Nov 1971 [17 Nov 1970] 52345/71 Heading H4F In a colour television display system employing a single electron gun colour display tube the  beam from which impinges sequentially on different colour producing phosphors in synchronism with the application of corresponding colour signals to the gun, an attenuator, operating synchronously with the application of the colour signals controls the beam intensity in an adjustable manner such that a predetermined light intensity is emitted in each of the colours. This arrangement allows correction to be effected for variations in the efficiencies of the phosphors. Figures 1 and 2, show the general arrangement in which shunts 30, 40 and 50 comprising adjustable resistors R2, R3, R4 are switched across the clamped video input to the output amplifier under the control of the red, blue and green synch. pulses. In the practical and preferred embodiment shown in Fig. 3, in which no shunt resistor is employed during the occurrence of the red signal (since the efficiency of red phosphors is lower than that of blue and green phosphors) the shunt resistors for blue and green, R2 and R3 respectively, are switched into circuit by transistor switches Q1, Q2 the base electrodes of which are supplied from a 6V bias source and via terminals RCB and BCG, with gating signals from circuits 70 and 80 respectively of Fig. 1. Any of the sequential video signals may be shorted to ground by means of switches S1, S2 (not equivalent to S1 and S2 of Fig. 2) a further transistor switch Q3 and switch S3 being provided for shorting the red signals. The input video signals are supplied via a known integrated circuit amplifier (detailed in Fig. 4, not shown) to an emitter follower Q4 feeding resistor R1 at the input of the shunt circuit, the base of Q4 being connected to a D.C. clamp circuit comprising D1, R4, R5 and R6 and C2 and C3. To provide for brightness control negatively-going pulses of adjustable height and to which D1 will clamp rather than to the blanking pulses in the video signal are combined with the latter. Instead of shunting the video input, the latter signals may be supplied to the tube cathode and the shunting arrangement employed to vary the bias on the tube control grid.

Abstract: 1527632 Apparatus for cleaning vertical surfaces SANKO CO Ltd 24 Dec 1975 [28 Dec 1974] 52856/75 Heading B7H An apparatus for adhering to vertical walls comprises electromagnets or' suction cups 14 for holding the apparatus on the wall, and means for sequentially separating a wall adhering member from the wall, moving it relative to the apparatus and re-fixing it to the wall. In a first embodiment the wall adhering members 14 are electromagnets and are mounted on piston-rods 15a of cylinders 15, the rods passing through bases 12 slidably arranged between guides 11 so as to be movable along the length of the apparatus by pneumatic cylinders 13. The apparatus is driven by an air or electric motor 6 through wheels 2 and wheels 3 are steerable by means of pneumatic cylinder 10. The members 14 are urged against the wall by springs (16), (Fig. 2, not shown) at the underside of bases 12 and are lifted clear of the wall when air is supplied the vertical pneumatic cylinders 15. A solenoid actuated valve system and electronic control circuit controls air supply to cylinders 13, 15 (Figs. 3, 4, not shown). In operation both magnets MG1, MG2 are energized and cylinders 15 opened to atmosphere to allow springs 16 to urge the magnets to the wall. Cylinders 15 are then supplied with air to raise the rods 15a and force the wheels 2, 3 against the wall. To move ,the apparatus the motor 6 is started and one magnet MG1 is de-energized and is lifted by its cylinder 15. The cylinder 13 attached to MG1 is supplied with air, the other cylinder 13 being open to atmosphere, to move MG1. The magnet MG1 is then re-energized and its cylinder 13 opened to atmosphere. The cylinder 15 attached to MG1 is then opened to atmosphere and its spring 16 moves the magnet to the wall, and the cylinder 15 repressurized to pull the apparatus back to the wall. During movement of MG1, the cylinder 13 of MG2 is open to atmosphere. The cycle is repeated for movement of magnet MG2. Synchronization of the operating cycle of the magnets with the drive wheels 2 allows smooth movement of the apparatus. In another arrangement, Fig. 13, the cylinder 13 is used to aid movement of the apparatus. Instead of the cylinder opening to atmosphere at the end of movement of the magnet, it is pressurized in the opposite sense to pull the apparatus up. The sequence of operations is otherwise the same as the first embodiment. The electromagnets may be replaced by suction cups, Fig. 11, of elliptical plan and having inner and outer resilient walls 25, 32, the outer wall being softer than the inner. The cup, bottom 26 has spaced plates 27 attached thereto, these being connected to the piston-rod 15a of cylinder 15 for flexing the cup. A suction line 30 is connected to the cup, In a further embodiment (not shown) the apparatus is not self propelled but is connected to a cable of a winch mechanism which acts to raise or lower the apparatus on the wall.
