Title: Improvements relating to the indication of movements at a distance
IPC: B64C13/02
Filed: 1934-07-27
Abstract: 442,078. Electric signalling systems. PATIN, A. K. F., 24, Badenschestrasse, Wilmersdorf, Berlin. July 27, 1934, No. 21994. [Class 40 (i)] In a system for indicating at a dis tancethe rotationa position of a mem ber having un limited rotation the balance of a bridge formed by closed impedance or resis tance loops at the transmitter and receiver is effected automatically and directly by coils which carry the out-of-balance currents. As shown, the member operates contacts 2, 3 relatively to closed resistance loops supplied at diametrical opposite points, to vary the current distribution in line wires 4, 5 which are connected through the crossed coils 6, 7 of the receiver to a similar contact arrangement operated by the receiver. The coils 6, 7 are rotatable in a magnetic field and the arrangement is such that the receiver always operates to maintain a resistance balance at the transmitter and receiver. In a modification, the transmitter and receiver are provided with three brushes displaced at 120‹ around the resistance loops and the receiver comprises three coils similarly displaced in a magnetic field. The resistance loops may be rotatable and the brushes stationary. The resistances may be replaced by loops of capacitative or inductive elements. Indications may be given of movements having more than one degree of freedom.

Title: A magnetic film memory
IPC: H01F10/14
Filed: 1965-05-25
Abstract: 1,092,289. Magnetic storage devices; lasers. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 25, 1965 [June 29, 1964], No. 22034/65. Headings H1C and H1T. [Also in Division H3B] Information is stored in an anisotropic thin film magnetic element by means producing a magnetic field along the hard axis which produces a stable state of magnetic remanence along that axis and second means producing a field in the opposite direction to the first field which destroys the stable state. In one arrangement a memory plane 32, Fig. 1, carrying anisotropic magnetic film bands 36 is arranged so that an electron beam 46 can be moved by a deflection yoke controlled by signal circuits (not shown) over the film bands. The remanent magnetization in the film bands is set in the hard direction by coils 52, 54, or by currents through selected conductors 44, to record " 0's " in the film areas. The field surrounding the electron beam scans the bands, unlocking the areas which it contacts from hard direction remanence, and these areas are then set to easy axis remanence (" 1's ") by a bias field from coils 68, 70. A beam 72 of polarized light from a laser 71 directed by a calcite light deflector control 74 by control circuitry (not shown) on to a film area to be read out is reflected by that area into an analyser 78 which may transmit light only when reflected from an area in a " 1 " state. This light is detected by a photomultiplier 80 which generates a suitable read-out signal. If the magnetic films have a high degree of variation of the angles of the individual dipoles about the easy axis the unlocking action of the electron beam on the hard direction remanent magnetizations may be assisted by a bias field produced by coils 52, 54. In another arrangement (Fig. 11, not shown) the electron beam and optical read-out arrangements are dispensed with and areas of an anisotropic film 90 are provided with row and column conductors 98, 100 arranged adjacent and parallel to the easy axis in each area so that any area can be locked in a hard axis remanent state by coincident current in its two conductors (a " 1 "). Interrogation is effected by oppositely pulsing only one of the two conductors of a region the read-out pulse being detected on the other and the film area being then in an " 0 " state with the dipoles in the film area directed in one or both directions along the easy axis. A " 0 " can be written into any area by unlocking it from hard axis remanence by coincident currents of appropriate value in its associated conductors.

Title: Improvements in ring spinning and doubling frames
IPC: D01H1/02
Filed: 1922-08-14
Abstract: 205,266. Potter, T., Fielding, F., Fielding, J. T., and Potter, T. Aug. 14. 1922. Spindle apparatus; building-motions; antiballooning arrangements.-Relates to means for enabling yarn to be spun or doubled upon the bare spindle in ring spinning or doubling frames, travellers of the usual bow formation being employed and the yarn guides being dispensed with. A ring 5 is mounted on the ring rail to control the yarn and to reduce friction between the ring and traveller; the ring rail is operated by a cam 6 so that it rises at a gradually increasing speed, which is suddenly increased at the nose of the cop, and falls at a high speed which diminishes after the rail has fallen a short distance but is at all times higher than the rising speed; the spindles are inclined towards or away from the rollers; and a wire 15 is provided on the ring rail to prevent the yarn coils slipping off the spindle. The apex 12 of the cam is set back and a projection 13 on the descending side serves to break the fall of the ring rail. The cam runs at a greater speed than is usual for spinning on bobbins. The rings 5 are preferably such as described in Specification 138,432, and assist the cam in obtaining a binding of the yarn at the nose of the cop. The wires 15, which are mounted in brackets 16 to allow of their being moved back to facilitate doffing, check ballooning and thereby prevent the yarn from being thrown off the spindle. The spindles are preferably formed with two parallel portions a, b, and intervening tapered portions c, d, e, and may be used either for weft or twist cops. When the cop is completed it is slipped upwards and the yarn wound on the exposed base of the spindle. When the invention is applied to an existing machine, a rotary lift is preferably used in place of the lever lift. Any suitable knocking-off motion may be used to stop the machine when the set of cops is completed.

In a valve actuator having an electric rotor and a control panel 11 including three pushbuttons 12, 13, 14 for controlling the energiza. tion of the motor, a cover assembly 22 is mounted on the actuator casing 10 over the' control panel 11, the cover assembly including an operating knob 31 and a selector disc 37 rotatable therewith to screen push-buttons 12, 14 and prevent manual operation thereof in certain positions. The spring-loaded push-buttons 12, 14 operate switches 19, 20 through plungers 15 to sense energization of the motor and opening or closing of the valve, and knob 31 is in certain rotational positions thereof movable axially to actuate a stop switch 21 through plungers 34, 15 to cause de-energization of the motor. The motor is alternatively operable by remote control means. When the knob 31 is turned to the " Full control " position, Fig. 1 (not shown), apertures in the selector disc 37 are aligned with corresponding apertures 25, 27 in a front plate 24 of the cover assembly bolted to the main actuator body, so that pushbuttons 12, 14 may be actuated manually and knob 31 may be depressed to actuate pushbutton 13. When however the knob is rotated to the position shown in Fig. 4, the selector disc 37 screens the push-buttons 12, 14 while at the same time the knob is locked in an outer position by means of pins 41 thereon engaging over lugs 43 around the central aperture 26 in the plate 24. Similarly, when the knob is turned to the " Stop locked " position lugs 43 so engage with the pins 41 that the knob is held depressed and the push-button 13 is permanently operated. In -the " Stop and remote " position the lugs 43 do not engage the pins 41 so that the knob 31 may be depressed though push-buttons 12 and 14 cannot be directly manually-operated. A spring- loaded pivoted lever 56 passes through in the cover 23 and engages one of a plurality of slots round the periphery of the selector disc to prevent unauthorized rotation of the disc, the lever being locked in position by a padlock 62. Specification 939,353 is referred to.
