Abstract: 1278453 Sanitary pad V R SNEIDER 10 June 1969 [10 June 1968] 29362/69 Heading A5R A pad such as a sanitary pad adapted to be mounted in an undergarment, comprises an absorbent fill member 22, an absorbent cover 23 adhesively retained on the fill member, an impervious back member 25, the edges of the cover being attached to the edges of the back member to enclose the fill member, and a non- toxic contact type adhesive surface, preferably rubber based, provided on the back member 25 having a pullaway cover 27 over the adhesive. The absorbent cover 23 is made from a non woven fabric, the back member from a plastics sheet such as polyvinyl sheet, and the pullaway cover 27 from paper treated with silicone. The absorbent cover 23 is attached to the back member by adhesive or heat sealing and the enclosed fill member (22) is # inch thick and made from fibres. The pads may be made by placing shaped fill members between strips of absorbent cover and back member material fed from rolls, then attaching the absorbent cover member the back member and cutting the assembled pads from the strips. Pads of various shapes are described (see Figs. 1 to 4).

Patent GB-1531336-A (GB)
Title: Motor speed control circuits
IPC: D06F34/08
Filed: 1976-07-16
Abstract: 1531336 Automatic control of speed MULLARD Ltd 16 July 1976 29698/76 Heading G3R  A control circuit for a washing machine similar to that disclosed in Specification 1266691 monitors the tachogenerator output so that if an interruption of the supply occurs during spinning, but the motor speed does not fall below the distribution speed the spin response voltage is reapplied to the control circuit thus avoiding loss of spinning time caused by the machine recycling from the washing speed through the distribution speed to spin speed. In the arrangement shown the series motor 1 is controlled by triac 3 whose gate electrode is supplied from a comparator supplied by a ramp voltage B and a reference voltage VR. The washing machine programmer energizes terminals IP1, IP2, IP3 for washing distribution and spinning respectively outputs the voltages SW, SD and SS accordingly-to produce a current output from I3 when gated by a signal on line F. The distribution timer 9 provides signals TE to the voltage generator 12 and a controlling signal on line T to the current generator 13. The timer 9 is enabled by the output of OR gate 66. The tachogenerator winding 5 supplies processor 6 which produces the enabling signal F to current generator 13, a feedback signal to comparator 2 and speed detector 10. A signal G supplies shorting transistor TR7 and speed detector 10. In operation the programmer will select input IP1 to generate a voltage on SW which causes timer 9 to reset and provide a low voltage input T to current generator 13 which together with the operation of start-up circuit 11 accelerates the motor to washing speed, e.g. 50 r.p.m., which is then maintained by the retroactive nature of the control circuitry. On selection of IP2, voltage SD is produced and voltage SW is removed so that timer 9 is enabled to produce a rising voltage signal T to generator 13 which adds an increasing current to the previous basic current. After a predetermined time a signal TE is generated to enable the output SS when input IP3 is energized and a further additional current component is generated to cause the motor to run at spin speed. If the mains supply now fails a detector 13 produces an output through OR gate G6 to reset timer 9 and thus supply low level signals TE and T to cause the motor to be supplied with washing speed current. The speed detector 10 monitors the  reduction in drum speed and if this remains above a predetermined speed, 110 r.p.m., outputs an over-riding signal SC so that the voltage SS is still produced when the supply returns and spin speed current is supplied to the motor. If the drum speed falls below 110 r.p.m. then a period at wash speed followed by a distribution operation and spinning ensues. The speed detector also provides a reset signal SL if the drum speed falls too low, e.g. to 20 r.p.m., and since the sequence of distribution and spin are dependent on the output signal of the tachogenerator a failure of this item will cause the control to recycle.

Title: Random event generators
IPC: H03K3/84
Filed: 1975-07-01
Abstract: 1517274 Random pulse generators BRITISH BROADCASTING CORP 1 July 1975 [4 July 1974] 29740/74 Heading G4D A random pulse generator includes two shift registers 10, 12 fed with random input signals and a plurality of gates 18 each connected to one stage of each register in a different order and having their outputs combined in a gate 20. The input 16 of one register may receive the output of the other. Gates 18 are exclusive- NOR while gate 20 is an AND-gate. If the input to the registers comes from a pseudorandom generator with a probability of ¢ then the probability of a pulse at 22 is (¢)<SP>n</SP> where n the number of stages and gates. In Fig. 2 the two registers are themselves combined with an exclusive-OR gate 40 as a pseudo-random generator. To further improve the randomness the output of a sample and hold gate fed with white noise is also combined in the gate 40. To vary the probability gates 24, 26, 28 are interposed between the exclusive-OR gates 18 and the final AND gate 30 and controlled by switches 32. In a more complex embodiment (Fig. 3, not shown) and using a fifty-five stage shift register operating at up to 17 MHz the probability can be set up on B.C.D. switches (124).

Title: High voltage isolators
IPC: H01H31/28
Filed: 1959-09-02
Abstract: 897,558. Linkwork. SWITCHGEAR & EQUIPMENT Ltd., and OXLEY, D. A. J. Aug. 31, 1960 [Sept. 2, 1959], No. 29982/59. Class 80 (3). [Also in Group XXXVII] In a high-voltage isolator in which a hinged switch-blade 11 is swung between a lowered closed position and a raised open position by the rotation of an insulator shaft 23, the centre of gravity of the shaft is lowered as the blade is raised and the mass of the shaft more than counterbalances the blade, at least when the blade is in and near its raised position so that the blade will not fall and close the circuit should the operating mechanism fail when the isolator is open. The blade 11 is supported in a trunnion bearing 20 carried by a transverse pivot 19 in a link 18, the end of the blade 11 being cranked at 22 at 45 degrees to the length of the blade. This cranked end 22 is received in a bearing 27 on the upper plate 25 of the insulator shaft 23, the bearing being inclined at 45 degrees to the vertical axis of the shaft and being offset from the vertical axis. The lower plate 26 of the insulator shaft is linked to a support-plate 30 on an inclined operating shaft 31 by means of a universal joint 28 offset from the axis of rotation of the plate 30 and from the vertical axis of the insulator shaft. To open the isolator, the shaft 31 is turned through 180 degrees, causing a corresponding rotation of the insulator shaft 23 and the lowering of the shaft 23 to the dotted line position, Fig. 2. This movement of the insulator shaft 23 causes the blade 11 to rotate through 90 degrees about its axis to release a contact cam 21 from fixed contacts 13, and also to swing about the pivot 19 to a substantially vertical position. In a modified arrangement the blade may be vertical when closed, the pivot being uppermost and the insulator shaft being horizontal. In this case the mass of the insulator shaft is disposed so that its centre of gravity is eccentric to the axis of rotation of the shaft and is in its lowest position when the blade is in its horizontal open position.
