Title: Speed control for a body of variable resistance
IPC: G05D22/02
Filed: 1950-08-22
Abstract: 679,076. Automatic moisture content control systems. DU PONT DE NEMOURS & CO., E. I. Aug. 22, 1950 [Nov. 25, 1949], No. 20728/50. Class 38 (iv). In a system for controlling the speed of a body of variable resistance, a portion of the body Forms an arm of a bridge circuit associated with an electronic valve which when conductive causes the speed of the body to increase another arm of the bridge circuit being associated with another valve which when conductive causes the speed of the body to decrease. As applied to apparatus for maintaining constant the moisture content of yarns, filaments, ribbons &c. during a winding process, the speed of the yarn &c. as it passes through a, dryer is controlled by a Wheatstone bridge 8 one arm of which includes stationary or roller electrodes 2, 3 over which passes the yarn 1, the resistances of which varies with the moisture content. The desired moisture content is predetermined by the variable balance arm R1 and the bridge controls through amplifiers T1, T2, the relays CR1, CR2 which respectively slows down or speeds up the speed of wind so as to facilitate correct drying and thus maintains moisture content constant. The bridges and the biasing resistors for the amplifiers T1, T2 are supplied through rectifiers T3, T4 and the relays CR1, CR2 control further relays CR4, CR5 which operate the pilot motor F for the control gear, e.g. a variable gap core of the main A.C. winding motor (not shown). With the machine shut down all the " stop " and limit switches 14 are closed and the " start " buttons 10 which are located at convenient places are open. When a start button is operated locking relay CR12 is actuated to start and run the main motor at its lowest speed over contacts X, Y, Z and at the same time prepares a circuit over " high speed " buttons 18 for relay CR6. One of the buttons 18 is then operated and relay CR6 completes the control circuit for the motor F from the contacts of relays CR1, CR2 the relay CR6 being locked up over buttons 20 which if operated restore the " slow speed " running condition of the main motor. As the machine has been stopped, the moisture content of the yarn is too low and hence relay CR2 is operated and a circuit is completed over a high-speed cam 7 for relay CR5 which operates pilot motor F to speed up the main motor. As the speed increases cam 8 closes contacts 34 and operates relay CR3 and transfers operation of motor F to variable inductance 37 which reduces the speed of the motor F to prevent overshooting. If now the moisture content in the yarns becomes too great relay CR1 operates a relay CR4 to associate the inductance 37 with the slow speed winding of the motor F and lower the speed of the main motor.

Patent GB-971985-A (GB)
Title: Improvements in or relating to electric signal sampling and encoding apparatus
IPC: H04B14/04
Filed: 1963-05-27
Abstract: 971,985. Electric selective signalling. G. BATTAIL. May 27,1963 [June 25,1962], No. 21012/63. Heading G4H. [Also in Division H4] A coder in a pulse code modulation system employs a conventional cathode-ray tube having a fluorescent screen which co-operates with an optical system and coding masks to produce a coded representation of the amplitude of the input signal the arrangement being such that sampling of the signal is effected within the optical system. As shown in Fig. 1,the electron beam of a cathoderay tube 1 is controlled in the vertical direction by the input signal applied via terminals 81, 82 and amplifier 8 to the vertical deflection plates 111, 112, and a scanning voltage from a source 6 is supplied to the horizontal deflecting plates 121,122, means being provided via a phase shift network 7 for suppressing the beam during flyback. The screen of the cathode-ray tube is masked with the exception of a slot 21 in a collimator 2 so that sampling is carried out when the spot 14 passes this slot, the height of the spot in the slot being determined by the input signal amplitude. Fig. 2 shows a section of the collimator 2 but rotated with respect to Fig. 1. The lenses 22, 23, 26 and slot 25 co-operate so that when the spot 14 is not in the plane V-V any light passing through lenses 22, 23 will be intercepted by the plate 24 but when the spot is formed in this plane the beam is aligned with the slot 25 and is transformed by the lens 26 into a divergent beam which appears to issue from a virtual point source slightly in front of the spot 14. The light beam from the lens 26 encounters eight objective lenses 301 &c., in an optical coding device 3, which produce an image of the virtual spot on each of the eight associated coding masks 311 &c., Fig. 4; which are arranged so that each image appears at a distance from the reference edge of each coding mask proportional to the instantaneous amplitude of the input signal at terminals 81, 82. The masks comprise alternate opaque and transparent strips producing a reflected binary code and co-operate with eight associated photo-multiplier tubes 411 &c. to produce voltage pulses across the appropriate load resistors 421 &c. In order to prevent errors which could arise due to the persistence of the luminous screen the signals from terminals 431 &c. are supplied via respective gates controlled through a shaping network 9 from the time base 8 to associated pulse discriminators also controlled from the network 9 which pass a signal only when a predetermined threshold voltage has been exceeded. The resulting signals are converted into serial form by a tapped delay line 5. In an alternative arrangement, Fig. 6 (not shown) the gate circuits are replaced by differentiating circuits.

Title: Improvements relating to the removal of yarn residue from bobbins
IPC: B65H73/00
Filed: 1962-05-31
Abstract: 934,032. Stripping waste from bobbins. G. ROHL. May 31, 1962 [June 9, 1961; Sept. 1, 1961], No. 21033/62. Classes 120 (3) and 142 (2). Apparatus, for fitting to a loom for the removal of yarn residue from bobbins, comprises a downwardly inclined track 3, down which bobbins slide, with their heads uppermost, a vertical tubular casing 10, spaced beneath the end of the track by a distance at least equal to the length of the bobbin stem, and is fitted at the lower end with a suction device and at the top end with a spacer 11 for engaging the head 6<SP>11</SP> of the bobbin to provide an annular suction opening between the top of the casing and the head of the bobbin. The apparatus also includes means for lifting the bobbin out of the casing, after the removal of the residue by suction. The bobbin head 6<SP>11</SP> advancing down two slide bars of the zig-zag track 3 drops on to the horizontal end 7 of the track and is stopped by the " stop " arms of two-armed levers 20, 21 mounted on a shaft 22. The head 6<SP>11</SP> depresses an arm 8 to close a microswitch 22 which starts motors for conveyer belt 17 and the suction blower, A stop 34 on the belt 17 strikes and rotates shaft 26 which, through gearing 24, 25, rotates shaft 22 so that the " feed " arms of the levers 20, 21 cause the bobbin to drop into the casing 10. Stirrups 18 now engage the head of the cleaned bobbin to carry it upwards to an ejection track 19 (Fig. 1, not shown). The next stop 34 strikes arm 36 of switch 35 to stop the two motors. The belt 17 may be driven from the loom. The spacer 11 is adjustable heightwise of the casing 10.

Abstract: 717,557. Proofing permeable materials: mould-resistant paper. DEUTSCHE GOLDUND SILBERSCHEIDEANSTALT VORM. ROESSLER. Sept. 2, 1952 [Sept. 4, 1951], No. 21060/52. Classes 96 and 140. Textiles and paper are impregnated with a solution of zinc thiocyanate in order to improve their durability. The treatment may be combined with known treatments for water-proofing, e.g. with aluminium salts or titanium or zirconium double salts. Water-soluble resin pre-condensates may also be added to the zinc thiocyanate solutions, especially urea-, dicyandiamide- and melamine-formaldehyde precondensates. If the zinc thiocyanate causes flocculation of the resin, the two treatments may be given in succession. In an example (1) hemp cords are soaked with a 4 per cent zinc thiocyanate solution and dried. A further example (5) describes the treatment of paper with a urea-acrolein-formaldehyde precondensate, aluminium chloride and zinc thiocyanate.

Abstract: 1,122,592. Hypodermic syringes. F. WANTOCH. 31 Aug., 1965 [19 May, 1965], No. 21155/65. Heading A5R. A hypodermic syringe, used to inject fluid from a replaceable flexible bag 6 through a needle 8, comprises two pistons 15, 16 able to be moved to a limited extent independently of each other inside a cylindrical barrel 1, the space 22 above the pistons receiving the bag 6 when it is filled with fluid (Figure 3, not shown), there being apertures 24 in the piston 15 and there being communication between the space 23 and the atmosphere through the hollow piston rod 17. Concentric hollow piston rods 17, 20 are used to move the pistons and, when filling the bag 6 from a separate container, the piston 16 is moved away from the piston 15 (into the position shown in Figure 2) to extract air from the space 22 into a space 23, thus ensuring that the bag 6 fills the space 22 completely. Alternatively, a pre-filled bag may be fitted into the syringe. The syringe is also provided with a clip device 10, 12 releasaby retaining the bag and the needle hub (3). A layer 25 of foam plastics material on the piston 16 is impregnated with a silicone lubricant to lubricate the internal surface of the chamber of the syringe. A device, Figures 7 and 8 (not shown), is pnovided on the piston 15 for gripping the bag 6. In an embodiment (Figure 6, not shown), one piston (52) is loosely contained within the other (50).

Filed: 1966-05-12
Abstract: 1,085,415. Ratchet clutches; slip couplings. GENERAL MOTORS CORPORATION. May 12, 1966 [May 20, 1965], No. 21166/66. Heading F2C. A clutch interposed between an aircraft turbo-prop engine shaft 6 and a propeller driving shaft 10 and disengaging under a predetermined negative torque, e.g. on engine failure, comprises an intermediate member 30 which is helically splined at 36, 38 on the shaft 6, is rightwardly urged by Belleville springs 42 to engage helical dog clutch splines 34 thereon with corresponding splines 28 on the shaft 10, and is leftwardly urged by negative torque, when the force of the springs 42 is overcome, to disengage the dog clutch splines 34, 28. The shaft 10, the propeller windmilling, may drive the shaft 6 (negative torque) up to the limit determined by the Belleville springs 42 for engine re-starting or to provide aircraft drag. The splines 36, 38 and 34, 28 are of opposite hand. To avoid attempted re-engagement of the dog clutch splines 34, 28, on disengagement, by residual engaging force of the Belleville springs 42, a multi-disc friction slipping coupling 66, loaded by a spring 64 is interposed between the intermediate member 30 and the shaft 10. The friction slipping coupling 66 provides a slipping drag on the intermediate member, on disengagement, to further leftwardly move and maintain the intermediate member 30 in its dog clutch disengaged position. The outer plates 62 of the coupling 66 are in high back-lash splined connection with the shaft 10, this feature (i) facilitating movement of the plates 62 axially of the shaft 10; (ii) rendering the coupling 66 inoperative under positive torque to thereby prevent an undesirable rightward torque responsive force, additional to the rightward force of the Belleville springs 42, on resumption of positive torque, such undesirable force producing impact loads should the dog clutch splines 28, 34 be misaligned; and (iii) permits some relative rotation between the intermediate member 30 and the shafts 6, 10 due to helical movement, thereby eliminating drag during re-engagement. The dog clutch splines 28, 34 have bevelled radial faces to facilitate re-engagement.
