Title: Magnetic storage devices
Inventor: STARR ARTHUR TISSO
IPC: G11C5/02
Filed: 1957-08-07
Abstract: 859,705. Magnetic pulse-storage circuits. STANDARD TELEPHONES & CABLES Ltd. Aug. 1, 1958 [Aug. 7, 1957], No. 31172/60. Divided out of 859,704. Class 40 (9). [Also in Group XXXV] An information storage element comprises a tube of magnetic material such as 80-20 Ni-Fe having a wall thickness not greater than 1/50 of the diameter and with read and write wires threaded through the tube. Typical dimensions are 0.005 or 0.010 inch diameter, 0.0001 inch wall thickness, and 0.025 or 0.050 inch long, the tube having a minimum length of <SP>5</SP>/ 3  of the diameter. Magnetic tubes may be deposited by an evaporation process on to refractory, e.g. ceramic or silica, sleeves threaded on a wire, either several evaporation sources being used or a single source employed, and the sleeves rotated. Alternatively the evaporated layer may be formed with a thickness in the order of 3000 Angstrom units while a concentric magnetic field is applied around the sleeves so as to establish single domain properties. Tubes having a thickness of 0.0001 inch may alternatively be drawn over a wire having a lower melting-point, followed by cutting into the required lengths and melting out the core. As shown in Fig. 4 (Provisional) input and output wires 16, 17 are positioned in a magnetic tube T1, and air coupling between the wires is neutralized to eliminate spurious outputs by arranging an opposing mutual inductance coupling which may be adjusted by movement of a glass tube T2. Magnetic tubes 30, Fig. 1 (Complete) may be arranged in a matrix with column and row wires 31, 32, information being stored by coincidently applying " half write " pulses to selected row and column wires, and the stored information being detected by a " full read " pulse applied to each row wire in succession.

Abstract: 801,360. Gramophone pick-ups. GENERAL ELECTRIC CO. Oct. 12, 1956 [Oct. 13, 1955], No. 31195/56. Class 40 (2). A variable reluctance type phonograph pickup is characterized in that means are provided for changing a stylus easily and quickly. The stylus 31 is mounted at the free end of a cantilever arm 29, fixed to a stylus support 28. Damping blocks 32 are provided as necessary. The assembly of stylus and support slides into a channel section member 19 which is secured to a post 13 journalled in a hole 12 in the plastic body 1 of the pick-up. The channel member 19 may extend on either side of the post and carry a stylus assembly in each end, the required stylus being brought into the playing position by depressing and then rotating the knob 15. In the playing position the stylus is located between pole pieces 8 attached to yokes 4 or 5 surrounded by coils 2 so that lateral movement of the arm 29 causes corresponding variations in the flux flowing in the coils and hence an output signal is developed. Specifications 680,684 and 685,293, [Group XXXIX], are referred to.
Patent GB-423621-A (GB)
Title: Improvements in slicing machines
IPC: B26D7/06
Filed: 1933-11-09
Abstract: 423,621. Slicing - machines. FITZPATRICK, H. D., 94, Hope Street, Glasgow.- (Maatschappij van Berkel's Patent Naamlooze Vennootschap ; 33, Boezemsingel, Rotterdam, Holland) Nov. 9, 1933, No. 31201. [Class 28 (ii)] In a slicing-machine wherein the substance is slid intermittently over a support 11 towards the slicing plane, the friction is reduced by the provision of rollers 31 which lift the substance from the support during the feed movement. The rollers are mounted in arms 32 independently pivoted at 33, and springs 34, each connected to one arm, tend to raise the rollers above the level of the support and thus to lift the substance. The lifting action of the springs 34 is prevented by stronger compression springs 38 which are threaded on rods 36 guided in brackets 37, the rods 36 being joined by a cranked cross-bar 35 which bears on, and depresses, the arms 32. The substance holder is, as usual, reciprocated parallel to the slicing plane, and at the end of the return stroke, i.e. the feed portion of the stroke, when the substance-engager is aligned with the gauge plate the roller ends 41, 42 of the rods 36 ride up cams 43, 44, to lift the rods in opposition to the springs 38. The bar 35 is thus released from the arms 32, which rise to enable the rollers to lift the substance from the support 11. The cams 43, 44 are offset relatively to each other, so that the roller 41 does not foul the cam 44. The invention is described as applied to a " push-pull " machine. According to the Provisional Specification, a stationary camlike member may hold the rollers inoperative, or the rollers may be mounted on eccentrics on a rockshaft journalled below the substance support and turnable, when the feed movement is due, into a position in which the eccentrics hold the rollers above the surface of the substance support. The rollers or the eccentrics may have spring mountings and the rockshaft may be operated by a stationary cam engaging an arm or roller on the rock-shaft. There may be two or more series of lifting rollers arranged to lift the substance entirely clear of the substance support for the feed movement.

Title: Apparatus for detecting the movements of objects
IPC: H01J17/04
Filed: 1933-07-29
Abstract: 427,785. Valve circuits; discharge apparatus. SPANNER, H. J., 308, West 231st Street, New York, U.S.A., and KRAMOLIN, L. L. DE, 25, Nassauischestrasse, Wilmersdorf, Berlin. July 29, 1933, No. 31257/34. Divided out of 420,522, under which a Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 30, 1933. [Classes 39 (i) and 40 (v)] [See also Groups XXXVI and XXXVIII] In apparatus for detecting the movement of persons or objects, an electric discharge tube with a conducting grid in the discharge path is energized with a voltage adequate normally to initiate a discharge, an external control conductor at a distance from the tube is energized to set up, between itself and a further conductor external to the tube and connected to the grid, an electrostatic field suppressing the discharge by inducing a charge on the grid, and a resistance leak is connected between the grid and a main electrode, preferably the cathode, of the tube. On the approach of an object to be detected, the field is distorted and the discharge is initiated. The grid is coated with insulating material and the conductor connected to it is equal in length to the combined length of the external control conductor and any unscreened part of the lead thereto. In a modification, the grid and the conductor connected to it are replaced by conductive coatings on the inside or outside walls of the tube, the field of the external control conductor inducing a charge on the walls and being distorted by the approach of an object. Narrow tubes not having the dimensioning described in Specification 420,522 are then used and the discharge is separated from the wall by apertured insulating chimneys allowing electrons but not ions to reach the wall. In all cases, the leak resistance is chosen to adjust the time constant of the control circuit to the greatest speed of movement of objects to be detected, and the lead to the external control conductor may be connected to a point of variable potential or contain a rotary plate condenser. This condenser may be replaced by a high or variable resistance but this resistance is omitted if the discharge current is required to increase steadily with the approach of an object to measure the distance away of the object. The tube may be energized with direct or pulsating or alternating current. For direct current, the control electrode in the tube is spaced from the main electrodes by a distance less than the mean free path of gas ions. The tube may have a cold instead of an incandescent cathode, for example, a photo-electric cathode of alkali or alkaline earth metal, and may be filled with rare gas or mercury vapour or mixtures or may contain a high vacuum. The tube may be resistance-coupled to a second tube and cascaded tubes may be combined in a single envelope providing a gas space common to all tubes. The apparatus may be adjusted so that oscillations commence on the approach of an object.

Abstract: 858,693. Ball-and-socket joints. LANGEN, V. Oct. 1, 1958 [Oct. 17, 1957], No. 31370/58. Class 65(2). The ball 2 is carried between highly elastic bearing members 4, 5, between which a cylindrical ring 6 of elastic synthetic material, e.g. a polyamide, is interposed. The ring may be of undulating (as shown) or zig-zag form. When the joint is assembled the bearing members are compressed against the ring, which is partly straightened out or pressed into the material of the members and thereby secured against rotation. Further compression can take place to permit the bearing members to move in the axial direction of the ball pin to take up wear.
