Title: Improvements in or relating to stencil duplicating inks
Inventor: CHAMBERS THOMAS SEAL
IPC: C09D11/14
Filed: 1953-10-13
Abstract: A stencil duplicating ink comprises an aqueous composition (free from hydrocarbon oils, fatty oils and oily derivatives of such substances, polyhydric alcohols and aldehydes) consisting essentially of water as the major diluent and carrier, a tinctorial agent, and a cellulose derivative soluble in water or in dilute aqueous solutions of alkali metal hydroxides, the cellulose derivative being a cellulose ether, a cellulose ester or an alkali metal salt of a carboxyalkyl cellulose present in such a proportion as to give the ink a viscosity of 35-150 seconds. Stormer measured with a standard cup with a centre baffle at 20 DEG  C. under a 200 gram load.  The composition may also contain a wetting agent such as a dioctyl ester of sodium sulpho-succinate, a quaternary ammonium salt, or a dibutylphenol sodium disulphonate. The tinctorial agent may be a water-soluble dye, e.g. a nigrosine dye, or a triphenyl - methane, rhodamine, thioflavine, auramine, quinone-imide, xanthone or sulphonated triphenylmethane dye.  It may also be a sodium sulphonate of a nitro, azo, pyrazoline, quinoline, triphenyl-methyl, diphenylnaphthylmethane, azine, xanthone, or anthraquinone dye. Alternatively the colouring agent may be an inorganic pigment such as carbon black, malachite green, iron blue or cadmium yellow. The composition may contain 2-15 per cent by weight of hydroxy ethyl cellulose or 1-10 per cent by weight of methyl cellulose or of sodium carboxymethyl cellulose, and the proportion of dye or pigment may be 3-15 per cent by weight.  Water-miscible solvents such as the lower monohydric alcohols, may also be present. The ink dries relatively quickly and may be used on hard paper stocks and highly finished impression media.  Specifications 615,744 and 676,373 are referred to.

Title: Line monitoring circuit arrangements for fault location determin atio
IPC: G01R31/08
Filed: 1971-06-18
Abstract: 1355089 Protective arrangements SIEMENS AG 18 June 1971 [26 June 1970] 28605/71 Heading H2K [Also in Divisions G1 and G4] In order to locate the position of a fault on a transmission line by determining the ratio of the reactive potential across the line to the line current when the fault occurs, a first sensor G1 which receives both the line potential U1 and the line current J1 produces a voltage U2 proportional to the reactive potential across the line, a second sensor G2 produces a voltage U3 proportional to the line current, the voltages U2 and U3 are both converted to pulse trains having corresponding frequencies f1, f2 respectively, and the ratio of the two frequencies multiplied by a scale factor x is determined by an arrangement Q including two counters Z1, Z2, and indicated on a device A. The result may also be printed by a device DE. Overall control of the system is effected by a device ST, which, when a fault is detected (by means not shown) and signalled to a terminal K1, resets the counters Z1, Z2 to zero over leads V4, V1 so that determination of the ratio can begin. Whilst the computation of the required ratio is being performed, a signal is produced by the control device ST on a terminal K2 which inhibits the operation of any protective circuit breakers, and this signal is maintained either until the required ratio is determined or until a preset duration has elapsed whichever occurs first. The system may also include an auxiliary distance-protection device DZ responsive both to the reactance to the fault and to the resistance to the fault, whereby the fault clearing region can be bounded on all sides, rather than merely by a preset value of reactance.

Title: Feeding and staking machine and method of making a connection
IPC: H01R43/04
Filed: 1968-06-18
Abstract: 1,220,734. Staking electrical connectors; jointing by stamping. THOMAS & BETTS CORP. 18 June, 1968 [26 June, 1967], No. 28995/68. Headings B3A and B3Q. [Also in Division H2] A feeding and staking machine for electrical connectors comprises a rotatably mounted wheel-like member 22 which receives a plurality of connectors 18, means 23 for indexing the member 22 between a connector-receiving station and a connector-staking station for staking a connector on the member 22 to at least one electrical conductor. A connector 18 is fed from a magazine 16 into the deep end of a groove 38 on the periphery of the wheel 22 so that a mandrel 43 of a mandrel assembly 41 passes through a central slot in the connector. Assemblies 41 are located in recesses 36 in the wheel 22 and as the wheel is rotated step-by-step they are reciprocated in the recesses by followers 44 engaging in a cam track. The wheel is rotated by a slide 52 provided with a spring-biased plate 58. During forward movement of the slide, the plate is pivoted outwardly by a chamfer on the end of a dowel pin 51 and when clear of the pin, the plate snaps back behind it. Simultaneously the end 65 of a spring-loaded lever moves into a groove 66, the lever being mounted on a plate 27, which with a plate 28 supports a shaft 26 on which the wheel 22 rotates. On the return stroke of the slide 52 the plate 58 abuts a pin 51 thereby rotating the wheel until the pin engages the lever 62, which has been raised out of the groove 66. The lever is lowered during the first part of each rotary step to allow a clear passage for the preceding pin 51. Downstream of the last pin 51 to be engaged by the plate 58, a spring-loaded kickback pin (67) engages another pin 51 to prevent rotation of the wheel as the slide is moved forwardly. Fig. 1 (not shown). The kick-back pin is disengaged by the pin chamfer as the wheel rotates on the return stroke of the slide. When a connector is held at the staking station with the wheel 22 stationary, the bared ends 95 of leads 96 are inserted into notches in the connector body and staking jaws 72 are brought together by the downward movement of a pair of cam blades 73. The staking grooves 77 form the connector into a generally hexagonal shape and the mandrel 43 remains in the slot so as to maintain its contour. The cam blades are actuated by a cylinder assembly 90 and they are opened after a forming stroke by springs (81) mounted on pins (79), Fig. 3 (not shown). The formed connection is removed manually and the wheel 22 is indexed to bring another connector 18 to the staking station. The operating cycle is controlled by an electrical circuit, Fig. 14 (not shown).
