Patent GB-1068325-A (GB)
Title: Improvements in or relating to electrical switching devices
Inventor: WALKER PETER ALBERT
IPC: G11C11/44
Filed: 1963-07-25
Abstract: 1,068,325. Superconductor devices. INTERNATIONAL COMPUTERS & TABULATORS Ltd. July 21, 1964 [July 25, 1963 (4)], Nos. 29508/63, 29509/63, 29510/63 and 29511/63. Heading H1K. In a switching device comprising a superconductor gate conductor magnetically coupled to an element of ferromagnetic material, means are provided for applying at least two different values of magnetic field to the ferromagnetic element so that it assumes different values of effective permeability thus altering the value of the self-inductance of the gate conductor. As shown, a controlled inductance device comprises a substrate 1 carrying a superconductive ground plane 2 of niobium on which is deposited a thin ferromagnetic element 3, which may be of a nickel-iron alloy and is preferably anisotropic with mutually perpendicular hard and easy directions of magnetization. A gate conductor 4 and a control conductor 5, both of superconductive material such as niobium or lead, are deposited over element 3 parallel to its easy axis of magnetization. Insulating layers (not shown) are provided between conductors 4 and 5 and between conductor 4 and ground plane 2. In operation, element 3 increases the self-inductance of gate conductor 4, but on application of a control current sufficient to magnetically saturate element 3 this self-inductance is reduced. An inductive branch circuit 7 is connected in parallel with gate 4 and the signal current divides between them in the inverse ratio of their self-inductances so that the change in inductance of gate 4 switches the major part of the signal current from circuit 7 to gate 4. Branch circuit 7 may be a simple superconductive loop or may be the gate conductor of a second controlled inductance device. Circuit elements to be controlled by the switching device may be included in circuit 7 and/or connected in series with gate conductor 4. All the conductors remain in the superconductive state throughout the operation of the device. In a second embodiment, Fig. 2 (not shown), the magnetic element is in the form of a circular area over which the gate and control conductors cross one another at right angles. Either the gate or the control conductor may be parallel to the easy axis of magnetization of the ferromagnetic element, the inductance of the gate in the absence of control current being high in the first case and low in the second. A plurality of control conductors may be provided for a single gate conductor. If full control currents are used the device operates as an OR gate, and if half currents are used additively then a device with three control conductors will provide a " majority " logic element. The devices may be used to form adders, bi-stable circuits or selection trees, and may also be used to sense the current flowing in a conductor of a cryogenic device.

Title: Process for the extraction of cellulose from vegetable matter
IPC: D21C3/26
Filed: 1948-11-15
Abstract: <PICT:0656506/IV (a)/1> Cellulose is extracted from vegetable matter by predigesting with either a caustic soda lye at 60-100 DEG  C. or a sodium carbonate lye at a temperature above 100 DEG  C., washing and then further digesting under pressure with an alkaline sodium monosulphite lye.  A temperature of 80 DEG  C. is preferred for the predigestion when caustic soda is used.  Cellulosic materials specified are straw, certain reeds such as Provence cane, and esparto.  The predigestion and washing steps may be effected in a continuous process as in the Figure: raw fibre 1, caustic soda 2 and an impregnating liquid 3 recovered from a later stage of the process are mixed in digester A from which the pulp 5 is withdrawn, and washed twice at D and F.  Black liquor 4, wash-water 6 and excess impregnating liquid from 3 are collected at 7 and regenerated at B by acidifying with sulphur dioxide from 8 and centrifuging.  The separated organic matter is washed with acid liquor which is recirculated with the black liquor 4.  The regenerated acid liquor 9 from the centrifuge B is neutralized and used for the second washing of the pulp.  The final digestion of the pulp may be carried out at 150-170 DEG  C.  The Specification as open to inspection under Sect. 91 also refers to the treatment of stalks of maize and bagasse.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1426486 Electric powered can-openers ETUD 26 June 1973 [30 June 1972] 30400/73 Addition to 1383839 Heading B8D In a modification of the can-opener of the Specification 1,383,839, wherein there is a drive which includes an electric motor and which is reversible to rotate both a traction wheel 24 carried in a pivotal member 41 and a cam 21 for pivoting the traction wheel on the pivotal member towards and away from a cutter, the drive reversal is effected by changing the direction of rotation of the motor itself by means of a rocker switch. The motor is a series motor carried on the pivotal member and, on depression of a key portion 36 of the switch to make contacts a 1 b and c 1 d, drives the traction wheel 24 and cam 21 through a worm and gear 26 and 25 to pivot the member 41 upwardly from a rest position 0 to a cam engaging position 0<SP>1</SP>. Cutting pressure between the cutter and wheel moves the arm on to position 0<SP>11</SP> against the bias of a spring stop 47. At the same time, a pin 39 on the member 41 holds the contacts closed. At the completion of the can-cutting operation, the spring stop 47 returns the pivotal member to position 0<SP>1</SP> thus allowing the contacts to open and the motor to stop. The key portion 35 is then depressed to make contacts bc 2  and da 2  to start and reverse the motor rotation and return the member 41 to its inoperative rest position. A modified switch, Fig. 6 (not shown), may be provided and include insulating blocks 48 separating the segments forming the contacts, and contacts a 1 -b and c 1 -d are held closed until can cutting is completed by a flexible lever 41 engageable by the pivotal member in its position 0<SP>11</SP>. Frictional contact between a lock washer 43 or a shoulder on the traction wheel shaft 32 and a cutter mounting plate 33, Fig. 6 (not shown), may function to return the arm from position 0<SP>11</SP> to 0. In a further modification, Figs. 8 and 9 (not shown), the cam follower pin 22 is replaced by a bellcrank element 51, which pivots against a spring when the cam has returned the arm to its in operative rest position 0 to prevent stalling of the motor.
