Title: Improvements in the preparation of purified latex and the preparation of rubber thererom
IPC: C08C1/08
Filed: 1941-08-26
Abstract: 551,666. Purifying rubber latex. BRITISH RUBBER PRODUCERS' RESEARCH ASSOCIATION (Rubber Research Institute, and Wentworth, V. H.). Aug. 26, 1941, No. 10870. [Class 70] In purifying rubber latex so as to obtain from it a rubber of reduced nitrogen content and increased resistance to absorption of water by the action of a proteolytic enzyme on the latex, the latex is concentrated by centrifuging or creaming, and the concentrated latex is diluted before the enzyme is added. The concentrated latex is diluted to a dry rubber content of 30-35 per cent. and is mixed with ammonia, a solution of papain or other proteolytic enzyme and sodium or potassium cyanide to actuate the enzyme.

Patent GB-629359-A (GB)
Title: An improved method of and apparatus for electric local and/or remote control
IPC: H02J13/00
Filed: 1947-10-23
Abstract: 629,359. Switching-systems; control by variable-frequency currents. WHITBY, E. Oct. 23, -1947, Nos. 10910/47 and 25530/48. [Class 38 (iv)] [Also in Group XXXVII] A frequency-responsive switching system, particularly for controlling the connection and disconnection of a consumer's non-essential load circuits by slight frequency variations of a remote generating station normally supplying these circuits, comprises a constant speed motor and a synchronous motor which runs at a speed proportional to the frequency of the generating station, the motors driving, respectively, and in opposite directions, the crown wheels of a differential gear, the planet carrier of which rotates a shaft carrying cams controlling contacts in the load circuits if the speeds of the crown wheels are unequal. The system may be combined with a maximum demand or overload cut-out arrangement for disconnecting some of the consumer's load circuits when his totaldemand exceeds a predetermined value. The two motors may normally run at the same speed so that the planet carrier is normally stationary, load switching being effected by temporarily increasing or reducing the station frequency to cause rotation of the carrier. Alternatively, the synchronous motor 13, Fig. 2, may drive the crown wheel 6 of the differential gear 3 at a speed normally slightly in excess of that of the crown wheel 2 driven by the constant speed motor 1, so that the carrier of the planet wheel 14 normally rotates and, through gearing 17, 18 and a slipping clutch 19 rotates the cam-shaft 16 to a position such that the cam switches 22-23 permit energization of all load circuits. A stop 21 prevents the cam-shaft from turning past this position, whilst the clutch 19 allows continued rotation of the planet carrier. To shed load the station frequency is temporarily reduced to such a value that the speed of the crown wheel 6 is less than that of crown wheel 2 so that the cam shaft 16 rotates in the reverse direction and progressively disconnects the load circuits, the operation being arrested when sufficient load has been shed by increasing the station frequency to such a value that the two crown wheels run at equal speeds. The constant speed motor may be an electrically-wound spring clock motor or a shaded pole or synchronous motor provided with an escapement device. The maximum demand cut-out arrangement may comprise a relay 59, Fig. 3 (not shown) having normally closed contacts in the supply circuit to motor 13, the relay winding carrying the total consumer load current so as to cause opening of the contacts on attainment of a predetermined load current. Motor 13 is thereby de-energized, so that motor 1 rotates the planet carrier in a direction causing the cam switches to shed load until the total load current is insufficient to maintain the relay contacts open. The least important loads should then be disconnected by isolating switches to prevent hunting of the system.

Abstract: 391,602. Type-making machines. WOLTERS, 0., 15A, Alte Ulrichstrasse, Magdeburg, Germany. April 18, 1932, No. 11048. [Class 100 (iii).] Strip-perforating machines ; justifying type.- In strip-perforating machines of the kind that are operated by circulating selector-elements resembling the matrices of a composing-machine, a units-counting mechanism for indicating the length of the composed line is operated by a feeding device, which engages the selectorelements in succession. In one arrangement, a units-wheel 3, Fig. 1, gears with a pinion 1, which is engaged by a number of toothed wheels 9 of different sizes, each wheel having attached to it a ratchet wheel 10. The ratchetwheels are each engaged by a pawl 14, Fig. 2, on a lever 13 carrying a feeler pin 16. Each selector-element B contains a hole located in a certain position, according to the size of the character represented by the element, and adapted to permit the passage of a single one of the set of feeler pins. One of the wheels 9 is thereby rotated, and a corresponding number of units is stored on the wheel 3. The feeler pins are spring-actuated under the control of a cam 17. Since the selector plates are of. varying thickness, recesses 16a of different depths are provided in an abutment plate 19, to enable the feeler pins to receive a constant stroke. In a modification the varying thicknesses of the elements are transmitted to a single toothed wheel by a single feeler pin, which engages holes located in the same position in all the elements. By change of the abutment plate 19, type of different founts can be measured. The length of the composed line and the number of units of shortage are indicated by a fixed pointer co-operating with graduations on the wheel 3.

Title: Solenoid error checking apparatus
IPC: G01R31/02
Filed: 1970-03-09
Abstract: 1,246,765. Checking circuits. NATIONAL CASH REGISTER CO. 9 March, 1970 [24 March, 1969], No. 11065/70. Heading G4H. A circuit for checking that one and only one of an array of solenoids 12 is energized comprises a sensing circuit 28 having an output 30 on which a signal appears when at least one of the solenoids has been energized and an output 32 on which an error signal appears when at least two of the solenoids have been energized and a logical circuit to which is applied the energization signal on terminal 10 and the output 30 is applied, the logical circuit being arranged to provide a further error output 32 if an energization signal appears in the absence of a signal at 30 or vice versa. One of the solenoids 12 is selected by a circuit 14 controlled by an input at 16. When the energization pulse is applied to terminal 10 the selected solenoid is energized through a silicon controlled rectifier. The energization pulse is also applied via one-shot circuit 22 to set flip-flop 24, and via an inverter 18 to gates 20 and 40. Sensing circuit 28 has input terminals 42, 44, 46, each coupled to one of the solenoids. The output 30 indicating that at least one solenoid has been energized is applied to the reset input of flipflop 24, to input 37 of gate 40 and to one-shot circuit 36 connected to circuit 38 resetting circuit 28. The reset output of flip-flop 24 is coupled to gate 20. Output 32 and the outputs of gates 20 and 40 are connected through an Or gate 34 giving an error signal on terminal 47. In normal operation the energization pulse causes one solenoid only to be set, so that there is an output at 30 but not at 32. The energization pulse is inverted to give a "0" at inputs 21 and 35 of gates 20 and 40 which are thereby blocked and no signal passes to Or gate 34. If no solenoid is energized in response to an energization pulse, the flip-flop 24 is set by the pulse and it remains set since no reset signal is applied from terminal 30. At the end of the energization pulse, therefore, the ouptut of the inverter 18 becomes "1" and gate 20 gives an output to Or gate 34. If a solenoid is energized in the absence of an energization pulse both inputs to gate 40 are "1" and an error output is produced. If two or more solenoids are energized, an error signal is produced at 3. The sensing circuit 28 (Fig. 2, not shown) comprises a capacitor for each solenoid. The capacitor is normally charged and is discharged as a result of the firing of the SCR to energize the solenoid. Current is drawn through a resistor providing a voltage drop which is applied to two transistors. One responds when only one solenoid is energized and both respond if two or more are energized. The resetting signal from circuit 38 re-charges the capacitors ready for the next cycle.
