[Also in Division A4] A device for making filaments by drawing comprises a reservoir 12 having a plurality of recesses 10 containing an air-drying viscous composition of filament forming material and a drawing member 14 having an equal number of protuberances 6. A sheet 11 of aluminium foil, rubber or polyurethane is attached to the surface of the reservoir 12 so preventing contact between the composition and air before the device is used. The drawing member 14 and the reservoir 12 are such that after the device has been used they may be pressed together hence sealing the composition from further contact with the air. In an alternative embodiment (Fig. 5) the reservoir is formed from a layer of absorbent material (16) such as natural or artificial sponge, felt wadding or pile fabric of wool, housed in a plastics shell (17). The co-operating drawing member has a drawing surface formed from another coarser sponge or reticulate fibrous mass (18) housed in a shell (19). The composition used in these embodiments is such that the filaments formed are adhesive to each other and to a slight extent to the hair but not to the skin. An example illustrates the preparation of polyurethane filaments. In use the reservoir and the drawing member are separated so drawing a plurality of filaments from the reservoir.

Abstract: 1,250,181. Desk calculators. BURROUGHS CORP. 23 Oct., 1968 [2 Nov., 1967], No. 50438/68. Heading G4A. In a digital computer, storage means receives data, macroinstructions and microinstructions from input means, each microinstruction containing the address of the next in a defined execution sequence, there being means to depart from this sequence. The computer is a desk calculator usable, e.g. for billing and having input means including a keyboard with alphabetic, numeric and programme-selecting keys, output means including a " golf-ball " printer and lamps, and a magnetic disc store with tracks for: macroinstructions and data, microinstructions, two recirculating loops (1-word and 4-words), and sector address and bit timing signals. The 1-word loop is used for synchronization on transfer to and from the store generally, and the 4-word loop holds operands during arithmetic and logic operations (e.g. using a serial adder-subtractor), a sequence of macroinstructions and the macroinstruction count (incrementable in the adder). The contents of the 4-word loop can be shifted in either direction by temporarily by-passing a 4-bit register normally forming part of the loop or by temporarily including in the loop a 4-bit portion of an input/output buffer register also used for transfer between keyboard, printer &c. and the rest of the machine. The 1-word loop can also be used for arithmetic and logic operations. A word in the 4-word loop can be exchanged for the word in the 1-word loop. The contents of the 1-word loop can be added into any word of the 4-word loop. The adder is binary and since the data is binary-coded-decimal, corrective sixes are handled by directly modifying the contents of the 4-bit register mentioned above as being part of the 4-word loop. Any 4-bit digit in the 4-word loop can be added to the contents of the 4-bit portion referred to above of the input/ output register, the result being stored in both. The input/output register, and a microinstruction register loaded from the disc store, supply address information for addressing the disc store. Normally each microinstruction specifies the address of the next, but alternatively the keyboard or other parts of the machine may intervene. A flip-flop is provided to permit the microstorage area of the disc to be augmented under programme control at the expense of the macrostorage and data area. The two loops may use semi-conductor registers rather than the disc. The microinstruction storage may be read-only.

Abstract: 1,265,204. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORP. 26 March, 1969 [11 April, 1968], No. 15840/69. Heading H1K. A drift field is produced in one or both of the base regions of a semi-conductor controlled rectifier by the provision of two zones of differing conductivity within the or each base region, the impurity concentrations within the two zones differing by at least an order of magnitude, and the zone of lower conductivity being situated adjacent the corresponding emitter region. In the embodiment shown both base regions are thus zoned, and the P-type base region includes a central third zone 222 having a higher conductivity than either of the other P zones 218, 224. The N-type base region includes a similar central high conductivity zone 208. The various regions and zones are formed by epitaxy or diffusion from an initially N-type Si body 202. The Al control electrode 230 may be applied to the zone 222 either through an etched aperture as shown or by alloying a P + zone through the N+ emitter region 226 and the P-type base zone 224 to the P+ zone 222.

Abstract: 1,265,599. Frequency measuring. GENERAL MOTORS CORP. 2 July, 1970 [17 July, 1969], No. 32084/70. Heading H3A. [Also in Division G1] In an arrangement wherein the direction of a magnetic field varies in accordance with a parameter to be measured, and a permanent magnet rotor controlling an indicator follows the field, an error compensation device responsive to the rotor position is provided, and varies an electric signal which controls the magnetic field direction so as to compensate for non-linearities in the system.  An arrangement is shown in Fig. 1, wherein the field is produced by the combination of currents through windings 18, 20. Pulses whose frequency is indicative of the speed of a vehicle are applied via diode 32 to the base of a transistor 38. This is rendered conductive, causing a capacitor 50 to discharge and hence causing transistors 42, 52 to shut off. Capacitor 50 then recharges through resistors 46, rendering 42, 52 conductive and shutting off transistor 38. This cycle is repeated at the frequency of the input pulses. A tachometer section 14 comprises a capacitor 56 which is charged and discharges again each time transistor 52 conducts, i.e. at each input pulse. The frequency of discharge of capacitor 56 affects the D.C. level at point 73 which depends on the current through 62, 64 and 68, the current through feedback capacitor 72 and the discharge of capacitor 56. The voltage at 73 controls an amplifier section comprising transistors 74, 78, 82 and 84. With no input pulses at diode 32, transistors 74, 78 and 82 are conducting near saturation; and 84 is cut off. Hence maximum current flows through a coil winding 18 and no current flows through coil winding 20. As the input pulse frequency increases, the input to the base of transistor 74 decreases and the current through transistor 82 and coil 18 decreases. Simultaneously current through transistor 84 and winding 20 increases.  The two windings 18, 20 are disposed (Fig. 2, not shown) in a plastics bobbin, and produce fields which are at 90 degrees, the resultant field being sensed by a permanent magnet rotor consisting of a disc magnetized across a diameter, this rotor driving an indicator 100 (Fig. 3, not shown) through gearing. To provide temperature compensation a thermistor 87 is connected across resistor 66 in the chain 62, 64, 66-thereby affecting the current input to the transistor 74 at the junction 73.  A further compensation network comprises a potentiometer 64 whose wiper arm is driven by the permanent magnet rotor. This affects the current input at junction 73 so as to compensate for non-linearities of the coil winding and armature unit.
