Title: Improvements in or relating to binary information storage and transfer systems
IPC: H03K17/82
Filed: 1958-12-12
Abstract: 890,185. Magnetic storage devices. BURROUGHS CORPORATION. Dec. 12, 1958 [Dec. 16, 1957], No. 40096/58. Class 38 (2). [Also in Group XXXIX] A magnetic core device for converting a binary one into a binary zero comprises an annular core 30 (Fig. 5) of square loop ferrite having a central shunting portion 32, input and output apertures 36, 38 and a clearing winding 40 linking the leg containing aperture 36 and passing through aperture 38. A current pulse through winding 40 produces a clockwise flux round the left-hand leg and leg 32, saturating the core material in the same direction on both sides of aperture 36 (the binary zero condition) and also a saturating anticlockwise flux round aperture 38 (the binary one condition). A large current pulse through input winding 42 (Fig. 6) switches the flux on one side of input aperture 36 and, being unable to reverse the flux in shunting portion 32 owing to a D.C. holding current through winding 34, switches the flux on one side of the output aperture 38, thus changing the flux at the output aperture 38 to the binary zero condition. Instead of passing a D.C. holding current through winding 34 it may be pulsed by the transfer current during the transfer operation. Alternatively winding 34 may be omitted, shunt core portion 32 having a permanent magnet embedded therein, or being replaced by a much longer shunt core portion (Fig. 8, not shown). The core may have arcuate slots (Fig. 9, not shown), and may be notched at the output aperture. It may have a plurality of input and output apertures, all the latter being linked by the clearing winding (Fig. 10, not shown). A transfer circuit incorporating the device is shown in Fig. 7. A first transfer pulse is applied to lead 1 from source 55, the current passed being sufficient to bring both cores 52 and 50 almost to switching level. If the core material at the output aperture in core 52 and also at the input aperture in core 50 has the flux set in the same direction on both sides of the aperture (the binary zero condition) nothing happens and the flux at the output aperture of core 50 remains in opposite directions on the two sides of the aperture (the binary one condition). If, however, core 52 is storing a binary one condition the transfer current linking with the output aperture in core 52 is able to produce local switching at that aperture, the resulting E.M.F. increasing the current linking with the input aperture of core 50 which results in the appearance there of a binary one condition and a binary zero condition at the output aperture in 50. Cores 52 and 54 are then cleared by a clearing pulse in lead 2, a transfer pulse applied to lead 3 then transferring the binary zero condition from the output aperture of 50 to the input aperture of 54. Core 50 is then cleared by a pulse in lead 4. Specification 890,182 is referred to.

Abstract: 1,016,176. Stuffer box crimping; packaging and coiling webs; heating. JOSEPH BANCROFT & SONS CO. Oct. 24,1962 [Nov. 7,1961], No. 40318/62. Headings D1F and D1T. Apparatus for crimping and packaging yarn comprises a stuffer crimper, with a crimping tube 10 in which a compacted web of crimped yarn is formed, a can 20 having a peripheral wall 33 and a central sleeve 31 forming an annular space to receive the web as it is discharged, and a mechanism for advancing the can at a predetermined rate with respect to the feed of the yarn to the crimper so as to lay the web in a succession of convolutions in the can. In the embodiment shown yarn 11 passes from package 14 and gate tensioner 13 to a traversing guide 16 which feeds the yarn axially along feed rolls 12 of the tube 10 which is of rectangular cross-section. The compacted web 37 may be heated by a block 9. Fixed to the top of the tube is a plate 38 fitting into the annular cross-section of the can and having a slot, through which the web is pushed, and a helical surface to conform to the web as it is laid. The can, having a perforated sleeve 31, is removably connected to the support 25 which is rotated by motor 28 so that the can is retracted upwardly on the threaded rod 26, Fig. 5 (not shown), the apparatus is the reverse way up and a discharge tube 46 is pressed against a spherical socket 47 on the discharge end of the crimping tube 10a. Eccentrics 52, 53 give a rotary movement to the tube 46 so that the web is laid in the can as a series of almost wholly overlapping coils. The crimper is pivotally mounted so that a filled can can be removed. After the removal of the package it may have a steam or liquid treatment and may then be mounted, for dielectric heating between an axial electrode and an annular electrode, Fig. 9 (not shown). Alternatively the package may be dyed or hot liquid or steam forced through the package which may be confined in a fabric sleeve.

Title: Improvements in or relating to extrusion apparatus
IPC: H02P5/46
Filed: 1957-12-31
Abstract: 887,265. Automatic control systems for extrusion of plastic fibres. INDUSTRIAL NUCLEONICS CORPORATION. Dec. 31, 1957 [Feb. 20, 1957], No. 40488/57. Class 38 (4). Groups of plastic fibres 54 from extrusion heads 36 are drawn out by a winder bar 56 rotated by motor 78 from which they pass on to bobbins 68, 70, 72, the weight/unit length of the fibres being detected by a radio-active (e.g. beta-ray) source and detector 80, 82, the latter producing a signal which is suitably centred on scale 104 by negative feedback network 93 of amplifier 90 (this measuring system being similar to that described in Specification 873,629), and compared with a " desired weight " reference voltage from network 120 which converts it into an error signal at the point 108. This error signal is balanced against the output voltage of a tachogenerator 138 by means of an amplifier 142 which energizes a servomotor 146 to adjust a speed controller 156 and the tachogenerator 138; since the error is thus balanced against the time differential of the speed of motor 22 the correction to the speed of the motor is proportional to the time integral of the error in weight of the fibres. This control system is similar to that described in Specification 887,267. The motor 22 drives pumps 12, 14, 16 supplying material to the extrusion heads 34, 36, 38 so that adjustment of the ratio of mass speed of extrusion to linear speed of fibres effects the desired control. Alternatively the pump 12-16 may be driven at constant speed and the speed of motor 78 controlled, or a single motor may be used for pumps and winder bar with a variable and controlled speed gear in the drive to pumps or winder.

Abstract: 1,209,354. Compensators for fluid pressure brakes. GIRLING Ltd. 4 Feb., 1969 [20 Feb, 1968], Nos. 8151/68 and 41729/68. Heading F2F. A compensator for an hydraulic braking system of the kind in which fluid under pressure is supplied to slave cylinders on wheels on opposite sides of a vehicle by separate master cylinders 35, 36 each operated by its own pedal, comprises a cylinder 19 adapted to be connected on opposite sides of a piston 26 working in the cylinder to the outlets from the master cylinders, the piston normally being held in a substantially central position in the cylinder by two oppositely acting springs 32, 33 of different strengths which hold the piston in engagement with a locating stop 24; the piston is free to move in either direction against the resilient resistance of the springs under differential pressures in the cylinder on opposite sides of the piston. As shown, the piston is provided with an O-ring seal 27 and has spigots 28, 29, the spigot 29 passing through a washer 31 held against a shoulder 24 by the spring 32 which is of greater strength than the spring 33. The cylinder 19, as shown may be integral with the master cylinders. An increase in fluid pressure in the smaller end of the bore 23 causes the piston to move to the right as seen in the Figure against the pressure of the spring 32 and assisted by the spring 33 and taking with it the washer 31, the travel of the piston being limited by the spigot 29. In the event of failure of a pipe line or other part of the hydraulic system on one side of the vehicle the piston moves axially until one of the spigots abuts the adjacent end of the cylinder whereby the brakes on the other side of the vehicle can still be applied. In a modification, the O-ring seal is omitted and rubber-faced sealing members provided on the ends of the spigots engage and close off ports at the ends of the cylinder.
