Patent GB-919340-A (GB)
Title: Improvements relating to position indicating devices
Inventor: KAY ANTHONY GILBERT
IPC: G01D5/243
Filed: 1960-12-05
Abstract: 919,340. Digital position indicating apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 5, 1961 [Dec. 5, 1960], No. 41764/60. Class 40 (1). The apparatus provides means for deriving a digital representation of the rotation of a shaft. The shaft 1 is connected through gearing 6 to the rotors of synchros 3, 4. The stators of the synchros are fed with 3-phase A.C. and the rotor outputs are fed to sampling circuits 12, 13. The phase of the rotor outputs depends upon the positions of the rotors. Circuits 12, 13 each give a pulse when the rotor output passes from positive to negative, and these pulses enable gates 14, 15. A counter 8 counts up to 100 repeatedly during one cycle of rotor output, so that the outputs of gates 14, 15 are the values indicated by the counter at the instant the relevant sampling circuit pulses. These counts are fed to the indicator 2. In order that the indicator shall step its second digit by one when the third and fourth digits have reached their maximum these latter digits feed a converter 16 which sends a bias voltage to circuit 17 thereby to vary the instant at which the rotor output passes through zero. Gates 21, 22 are provided to ensure that no signal passes to gates 14, 15 when counter 8 is changing from one count to the next.

Title: Process for dyeing or printing polyester or polyamide fibres
IPC: D06P5/04
Filed: 1977-10-10
Abstract: Pad dyeings or coloured prints produced on web-like textile two-dimensional structures which consist entirely or partially of polyester or polyamide fibres or filaments are fixed in the presence of methylene chloride by allowing the padded or printed structures to dwell, directly or after an interpolated intermediate drying, together with an adjacent material, also in web shape, in a rolled-up, plated or festoon form. The adjacent material may be in the form of either a separate web-like two-dimensional structure or be bonded by one of its two surfaces onto one surface of the web-like textile two-dimensional structure. The separate web-like adjacent material is impregnated with liquid methylene chloride before being brought into contact with the textile two-dimensional structure. If one surface of the textile structure is already bonded to the adjacent material, the liquid methylene chloride is applied to the outer surface of the adjacent material.

Abstract: 1314839 Automatic temperature control systems HUGHES AIRCRAFT CO 3 Sept 1970 [27 Oct 1969] 42212/70 Heading G3R A bonding tip electrical heater has a positive temperature co-efficient so that current pulses of constant amplitude flowing therethrough provide an increasing potential difference. At a determined voltage a work cycle is initiated, and the tip is maintained at a substantially constant temperature during the cycle. A start switch 100 Fig. 3 is closed to initiate the cycle, which switch may be closed when a capillary tip 11 is pushed on to a workpiece with a predetermined force, hence a flip-flop 21 is set and a transistor Q5 rendered conductive so that a turn on pulse is applied through a terminal 34 to a transistor Q3 Fig. 2 controlling through a transistor Q2 thyristors SCR1, 2 supplying power through a transformer T1 to tip 11. As the tip heats its resistance increases hence the voltage across the heater sensed by a transformer T2 Fig. 3 changes. At a temperature determined by potentiometer 18 connected to a differential circuit including transistors Q9, Q11, a transistor Q10 sets a monostable flip-flop circuit 19 for a period determined by resistors R24, R25 e.g. 10-100m/sec. Power is turned off for this time. Another monostable flip-flop 20 having a longer period and set simultaneously with flip-flop 19 controls the length of the heating period at the end of which bi-stable flip-flop 21 is reset ready for another operation. The thyristors are controlled by variable angular delay set by potentiometer R5 and capacitor C1 in a relaxation circuit including uni-junction transistor Q2. To compensate for mains voltage variations a potentiometer R11, R12 is connected across the supply and voltage from the common point D is rectified and smoothed by D10, C14 hence varying the potential at the right hand end of the potentiometer R5 in such a way as to compensate for mains voltage variations. The control circuits are fed from a regulated voltage arrangement 15 which also supplies stabilized and synchronise pulses to the control circuit 16. A plurality of tapped resistors and a selection switch may be provided to adjust the duration of heating, also the temperature levels sense may be varied by another group of tapped resistors and corresponding selector switch.

The spindle of a multiple part two for one twisting spindle is provided at the level of a yarn disc 16 with a transverse recess 7 into which a shaped part is inserted, the shaped part consisting of two plastics matching parts 8 and 9 with an intermediate matching part 10 made from wear resistant material e.g. sintered corundum housed therebetween. The parts define between them a curved yarn guide channel 11 inside which yarn entering vertically in the centre from stationary tube 4 is deflected along the curved path of the channel into the radial direction. When part 10 becomes worn due to yarn rubbing against it can be replaced by merely removing part 9 from the recess. The parts 8 and 9 are preferably made from flexible plastics material such that when inserted in the recess they are held in position by slight deformation. Matching surfaces 12, 13 are roughened or formed with small knobs, grooves or fins to compensate for slight measurement tolerances. The shaped part may define two curved guide channels in which case it consists of a symmetrical plastics lower part and the upper plastics matching parts of identical shape which between them house a symmetrical intermediate part of wear-resistant material, (Figs. 5 and 6).

The housing of a thermographic copying machine for "front printing" comprises two relatively movable mating portions, one of which contains a hollow aluminium rotary print roll 32 and the other a source 20, 22 of radiant energy directed on to the roll 32 thus defining a printing station between a supply roll 24 and a motor driven take up roll 18 for a transfer sheet 30. The housing has a slit 46 below the roll 32 to allow an indicia bearing original sheet to be inserted therein, a copy sheet 40 from a roll 26 being sandwiched between the original and transfer sheets with the indicia against the copy sheet. The relative movement between the two portions of the housing permits the print roll to be moved out of contact with the sheet 30 to facilitate changing of this sheet.

Abstract: 1,012,038. Time switches. VENNER Ltd. Dec. 20, 1961 [Dec. 20, 1960], No. 43808/60. Heading H2B. A time switch for controlling heating of buildings is modified to provide automatic adjustment of switching time in accordance with changes in external ambient termperature. A clockwork or electric motor drives a shaft 8 carrying a boss 1, a base plate 11 with " on " switching arm 32, an " off " switching arm 5, and a calibrated time dial 3, all of which can be mutually adjusted and then locked by tightening nut 10. A switch (not shown) is operable by lever 36 engageable by a pin 35 depending from the end of an arm 7 which is loosely carried on boss 1 and urged in the direction of arrow A (Fig. 2) by a spring which is not strong enough to move lever 36. The time dial 3 and arm 5 have been removed in the plan view of Fig. 2. Arm 7 carries an arcuate member 33 having steps 34 for engagement by an arm 32, which is carried on the ends of two bimetal strips 25, 26 attached by screws 27, 28 to a block 17 pivotally mounted at 18 on block 16. The arm 32 is thus movable between base plate 11 and dial 3 according to thermal response of strips 25 and 26 and its mean position is adjustable by screw 19. Arm 7 is normally held against a stop 37, and arm 32 is thus free to be thermally moved. The assembly is driven counterclockwise (Fig. 2) until lever 36 is engaged by pin 35. The arm 7 is then restrained from further rotation until the arm 32 engages one of the steps 34 depending upon its thermally controlled position, as shown in Fig. 2, wherein, for example, the temperature, and hence strips 25, 26 have risen above the mean setting. The arm 32 then moves the member 33 and pin 35 to operate the switch lever 36. A back stop 38 limits the extent of the thermally controlled switching delay.
