Patent GB-1102499-A (GB)
Title: Improvements in or relating to a magnetic-core data storage circuit
Inventor: BARNABY BERNARD SYDNEY
IPC: G11C11/06
Filed: 1965-07-06
Abstract: 1,102,499. Circuits employing bi-stable magnetic elements; automatic exchange systems. GENERAL ELECTRIC CO. Ltd. 6 July, 1966 [6 July, 1965], No. 28582/65. Headings H3B and H4K. Read-out and automatic re-write of a magnetic core (such as core 16 in a row of twelve such cores used to switch a multiplex highway gate 8, which is switched in one out of twelve times slots depending on which one of the twelve cores is switched) is effected by a readout pulse on wire 17 followed by a half-write pulse on wire 18, output current in row wire 22 charging capacitor 26 over the emitter-base circuit of transistor 23, the potential on capacitor 26 cutting-off transistor 23 when charging current ceases so as to cause transistor 25 to conduct and supply row wire 22 with a halfwrite pulse in conjunction with the half-write pulse on wire 18, the core being thereby automatically reset. At the same time, transistor 24 conducts to open the symmetrical transistor 8 comprising the highway gate. The cores of the row are pulsed sequentially with read-out and half-write pulses in the respective time slots associated with each core. When the highway gate is idle, no core in the row is set. When the gate is required for use, as for a calling subscriber, a bias is put on wire 49 of a core 44 so that the first pulse of a train of pulses on wire 47 representing free time slots switches the core 44. Output in winding 45 of core 44 cuts-off transistor 23 to produce the consequent half-write pulse in wire 22 of the row of cores 16 so as to switch that core of the row associated with that time slot. The switched core thence forward switches the highway gate 8 in the chosen time slot. In a 100 line P.A.X., each subscriber has a row of cores such as the row 16, the column wires 17, 18 correspond to time slots in the time division cycle. To terminate a call the core 44 associated with the called subscriber is switched by a single pulse applied to winding 48 of the core in the time slot of the calling subscriber.

Title: Improvements in or relating to the production of phonograph and like sound-records from filamentary or strip-like materials
IPC: G11B3/70
Filed: 1929-09-26
Abstract: 340,582. Moulding phonograph records. BRITISH FILOGRAPH CO., Ltd., and COWLEY, H. E., 83, Cannon Street, London. Sept. 26, 1929, No. 29233. [Class 87 (ii).] A sound record in the form of a thread is moulded under pressure by using a master record in the form of a cylinder or disc. In apparatus in which a cylindrical master record 34 is used, a set of supply and receiving bobbins 21, 22 are mounted respectively on discs 18, 19 carried by a shaft 17 driven from a motor 14 through suitable gearing. The shaft also carries a spider 20 having a series of plungers 26 of square cross-section and pressed radially outwards by springs 27. At the end of each plunger 26 is pivoted a carriage 28 which carries a spring-urged pressure roller 29 and which is guided by rollers 30 along a circular track 31 on the interior of a fixed bracket 13. The master cylinder 34 is carried by a shaft 33 driven from the motor 14. The thread-receiving bobbins 22 are driven from a friction wheel 59 through members 65, 67, 68 the wheel 59 being driven from a shaft 47 geared to the motor 14. The drive to each bobbin is started and interrupted as the associated thread enters and leaves the groove in the master cylinder by engaging and disengaging the friction wheel 65 with the wheel 59. For this purpose the wheel 65 is spring pressed against a sleeve 71 loose on the spindle 66 and having a cam surface 72 engaging a fixed abutment 73. The sleeve 71 has an arm 75 which engages a fixed cam disc 77 and at the correct time the sleeve 71 is moved axially to engage or disengage the friction wheels 65, 59. To wind the thread evenly on each receiving bobbin 22 the latter is moved axially along its spindle by a reciprocating carriage 83 having arms 85 engaging the ends of the bobbin. The carriage 83 is connected to a lever 87 pivoted at 88 and connected by a bar 90 to a cam 91 which is driven by reduction gearing from the bobbin spindle 69. The upper part 101 of the bobbin spindle is hinged to the part 69 to facilitate removal of a wound bobbin. The part 38 of the track 31 is straight and to facilitate the entry of each thread in the groove of the master cylinder the latter is supported between two tapered end pieces 42, and the beginning and finishing grooves may be deeper than the remainder. The master cylinder may be heated and if desired chemical baths or heating and drying ovens may be introduced between the cylinder and the bobbins. Several master cylinders may be spaced around the shaft 17 so that as the thread leaves one cylinder it enters the groove of the next. Reference has been directed by the Comptroller to Specifications 11722/15, 100,400, 280,923 and 285,965, [all in Class 40 (ii), Phonographs &c.]

Abstract: 1,021,743. Tyre deflation indicators. A. L. COURSE. July 24, 1963 [July 31, 1962], No. 29286/63. Heading B7C. In apparatus for indicating tyre deflation in a moving vehicle, a radio transmitter on each wheel generates a signal which is received in the driving cab to indicate when a tyre loses pressure. Fig. 1 shows a device for mounting on a twin-tyred wheel in which tubes 6, 14 connect bladders 5, 13 to the two tyre inflation valves, so that the air pressure in each tyre is received in the corresponding bladder and balanced against a spring-loaded plunger 7, 15. Levers 11, 18 pivoted to plungers 7, 15 are moved on loss of tyre pressure (left-hand side of Fig. 1) to close contacts 23a, 23b which complete a circuit between a battery 22 and a transmitter 25, so that the transmitter sends out a signal via its aerial 26. The signal is picked up by a receiver (Fig. 2, not shown) which actuates an audible and a visual warning device on the driving cab dashboard. A visual indicator 34 on the wheel may indicate which of the two tyres has deflated. Screw caps 9, 17 enable the pressures applied to bladders 5, 13 to be varied, and studs 35, 36 coact with beads 37, 38 to prevent damage to the bladders when they are deformed. The transmitter 25 may include a transistorized Hartley or Colpitts oscillator. Fig. 1 also shows a centrifugal switch 28 which is arranged in series with contacts 23a, 23b so that the transmitter 25 will signal that a tyre is deflated only when the wheel is rotating, switch 28 sliding on lever 11 to close contacts 28a, 28b.

A tool for loosening screws such as those in lawn mower blades comprises a rigid frame supporting a bit for engaging the screw head and co-axially therewith a centre or anvil mounted on a screw threaded stem which engages a screw thread in the frame so that a screw having both ends exposed can be firmly gripped between the bit and the centre or anvil. The frame, Fig. 1, comprises two rigid castings 10 and 11 connected together by bolts and nuts 12, 13, the bolts passing through tubes 14. The frame is fixed to a bench by means of the bracket 24 or it may be held in a vice. A screwdriver bit 19 is held against axial movement and rotation in a socket 18 projecting inwardly from the casting 11. The centre 22 is carried by a stem 21 having a screw thread 20 which engages a threaded hole in the casting 10. The centre is adjusted until it engages a centre punch mark in the end of the screw. To loosen the screw the blade and supporting bar are turned relatively to the frame. A bit having a plurality of teeth is used for gripping badly worn screw heads. In a modification, Fig. 2, the tool comprises a U-shaped frame 26 having mounted in the arms thereof the centre 30 and bit 35 which are both adjustable. The externally threaded socket member 29 carries the centre. The socket member 33 which carries the bit has a left hand thread engaging an internal left hand thread on a bronze bush 32 rotatable in a plain hole in the frame. A screw 36 extending into the outer end of the socket provides an adjustable abutment for the bit. The screw 37 is loosened by applying a spanner to the head 34 of the socket member 33.
