Title: Speed control of stranding equipment
IPC: D07B7/02
Filed: 1967-12-01
Abstract: 1,204,700. Driving stranding machines. GENERAL CABLE CORP. 1 Dec., 1967 [20 Dec., 1966], No. 54720/67. Heading D1T. A cable-stranding machine of the kind in which there are a plurality of supply bobbins angularly spaced about the cable by a rotatable frame, and feed means for advancing the finished cable, is characterized by means for speeding up the rotation of the frame and said feed means as the diameter of the reels of wire on the bobbins decrease. The frame and the feed means are in substantially constant speed relationship. The decrease in diameter of a bobbin is sensed by the resulting increase in rate of rotation of the bobbin. This increase in rate of rotation of a bobbin may be determined by means of a generator responsive to the speed of rotation of the bobbin holder. The rotatable frame and the feed means are driven by a common motor, the feed means or the rotatable frame being connected to said motor through a variable speed transmission that is adjustable to change their relative speeds and so change the lay of the cable. In Fig. 2 the bobbin 44 drives a tachometer generator 50 coupled to a voltage divider or inverse function generator 66. Another tachometer generator 70, driven by the main drive motor 22, is also coupled to the generator 66. The generator 66 supplies a control signal to an integrating circuit 76 controlling a siliconcontrolled rectifier 78 connected with the field of the main drive motor 22. Thus the speed of the motor 22 can be caused to increase in a manner causing the output of the tachometer generator 70 to match the ever increasing output of the tachometer generator 50.

Abstract: 1488368 Electrotherapeutic apparatus K SATO 20 Dec 1974 [28 Dec 1973] 55202/74 Heading A5R Electrotherapeutic apparatus for applying current via electrodes to the body, produces A.C. with a fundamental frequency of 250- 6000 Hz, a voltage not exceeding 300 V, a current not exceeding 50 mA and a waveform consisting of groups of 1-16 waves separated by intervals having a duration of 0.5-3.5 cycles of the fundamental frequency. Alternate groups may be of opposed phases, and may differ in the number of waves by one, a preferred arrangement being four waves alternating with three waves of the opposite phase. Apparatus for producing a group of two waves, an interval of half a cycle and a group of two waves of opposite phase comprises an RC oscillator 2 including an integrated circuit IC 1 , which may be of CMOS type, producing a triangular waveform at terminal a. and a sinusoidal waveform at terminal b. A wave-shaping section 3 converts the triangular waveform to a rectangular output which enters an arithmetical unit 4 at a NAND gate NG n  used as an inverter. An integrated circuit shift register IC 2  has a first input C1 and outputs Q 1-4 , initially all at higher voltage lever (true), Fig. 2 (not shown), which are connected to a second input D 1  through a NAND gate NG 1 . Successive pulses entering IC 2  at input C1 set Q 1 , Q 2 , Q 3 , Q 4  false in sequence, finally restoring the register to Q 1-4  all true. An integrated circuit IC 4  forms a switching signal G 1  from the logical sum of the inverted outputs of Q 1  and D 1 ; an integrated circuit IC 3  forms a switching signal G 2  from the logical sum of (i) the logical product of Cl and Q 2  (ii) Q 3  (iii) the logical product of C1 and Q 4 .

Abstract: 1,249,310. Television signal recording. COLUMBIA BROADCASTING SYSTEM Inc. 22 Nov., 1968 [24 Nov., 1967], No. 55576/68. Heading H4F. Video signals from pairs of successive fields produced by a television camera 10a are recorded on black and white cinematograph film in interlaced relationship in a single film frame. To shorten the number of film frames needed to record a program of a plurality of pairs of interlaced television fields the signals are passed through a one-field period delay means 18, and the delayed and non-delayed luminance signals are alternatively sampled at 27 at a frequency high relative to a line period whilst the spot producing the raster on the printing cathode-ray tube 28, Fig. 1, is subjected during the display to a castellated line scan, Fig. 2A, of said sampling frequency, such that the successive luminance fields are laid down in a dot-interlaced manner, e.g. field 1 on line portions 39 and 42 and field 2 on line portions 41 and 43. Vertical sync. pulses control the continuous film drive. To ensure that the delay of the delayed video signal is exactly one-field period, a small variable delay 19 is used, servo controlled by the output of a phase detector 22 determining the phase difference between sync. signals from the delayed and non-delayed video signals. The high frequency sampling signal is produced by generator 27a and is also added at 34 to the vertical deflectors signal from the tube 28. As an alternative to the above sequential sampling with a single beam, a recording beam tube 28<SP>1</SP>, Fig. 3, using two beams may be used, beam 1 recording lines 39a, 42a, Fig. 2B, from the delayed first field of a pair and beam 2 recording interlaced lines 41a, 43a<SP>1</SP> from the second field of the pair. Continuous film movement is again used, and each field is recorded twice in consecutive film frames. In the arrangement of Fig. 4 a twobeam tube 2 is again used. Delays 62 and 64 delay the successive fields A 1 , B 1 , A 2 , B 2 , A 3 , B 3  &c. for one and two-field periods respectively. A gate 66 passes the undelayed field signals, and the two-field period delayed signals on successive fields under the control of sync. generator 16. Beam 1 is modulated with the output of the gate 66 and beam 2 with the output of delay 62. The action of the circuit may be summarized by the following table:

Abstract: 1390070 Drawing WESTFALISCHE UNION AG 4 Dec 1972 [11 Jan 1972] 55930/72 Heading B3P A negative pressure, e.g. 30-50 Torr is produced in the interior of a drawing drum 3 in order to evaporate cooling water, supplied to the drum interior. In one embodiment, a suction is produced within the drum 3 by a vacuum pump 9 connected to a pipe 20, passages 21 in the drum hub or shaft 2 and a suction pipe 6 extending down to the lower end wall of the drum 3. Cooling water is caused to be drawn from a tank 13 and sprayed by pipes 10 onto the hot inner wall of the drum 3, whereupon it is evaporated due to the reduced pressure within the drum 3. Water is removed through the suction pipe 6 into a condenser 7 which has an outlet 8. In another embodiment (Fig. 1, not shown), the suction and water cooling pipes 6, 10 are mounted in a stationary member (5) surrounding the drum shaft 2 at the lower end of the drum 3.

Abstract: 1,268,350. Settling tank with rotary sludge rake. UNION CORP. Ltd. 25 Nov., 1969 [26 Nov., 1968], No. 55991/68. Heading B1D. Hollow tubular sludge rake arms 2 are mounted for rotation about central column 6 in settling tank 1 and are also capable of pivoting about their inner arms 4 to ride over obstructions, and pipes 15a, 18a enable the arms to be variably filled with water or compressed air to vary their buoyancy and thus adjust their normal position relative to the tank floor. In Fig. 2, both pipes are brought back to the central column where are provided couplings for water reservoir 24 and a compressed air supply. In Fig. 1, not shown, pipe (18) extends up from the outer end of arm 2 and is pivoted to prevent it catching on bridge (13) when raised. Pipe (15) is used to supply water to arm 2, which may be emptied by delivering compressed air to pipe (15) or (18) or pumping water from pipe (15) while pipe (18) serves as a vent. Bridge (13) carries sludge inlet pipe (14). In both embodiments, the rake rotation must be stopped to adjust buoyancy, but rotary couplings and valves could obviate this. The arms 2 are pulled round by tie ropes (7) extending forward to radial drive arms (9) and other ropes (12) determine their lowermost positions (Fig. 1). Buoyancy could be adjusted using hollow chambers other than arms 2.
