Title: Electrical Connections and Method of Making Same.
IPC: H01R4/56
Filed: 1967-12-19
Abstract: 1,177,558. Brazing. GREAT LAKES CARBON CORP. 19 Dec., 1967 [28 Dec., 1966], No. 57711/67. Heading B3R. [Also in Divisions C7 and H2] Contact resistance between engaged threaded portions of a conductor bar 6, e.g. of copper, aluminium, steel or carbon and a carbon body in the form of a graphite plate or pins 3, is lessened by interposing between the threads a molten alloy 4 of the kind which expands on solidification and which has a melting-point between 95‹ and 300‹ C. The conductor 6 is mechanically and/or chemically cleaned and the threaded recess of the carbon body is cleaned by compressed air. The molten alloy is poured in the recess of the body 3, which is heated above the melting-point of the alloy and the bar 6 is threaded into the recess so that the molten alloy rises between the threads. Alternatively, pellets or powder of the alloy may be deposited at the bottom of the recess and the temperature of the assembly is raised above the said melting-point. When the carbon body is a plate, the areas adjacent to the recess are reinforced with graphite or carbon strips or by a thick layer of material left during machining. The end 5 of the carbon body in use is connected to an anode plate of an electrolytic cell, e.g. a mercury-cathode chloroalkali cell. Alternatively, a carbon pin may be externally threaded for engagement in a threaded recess in a conductor body. Examples of suitable alloys are: 58 Bi, 42 Sn; 55À5 Bi, 44À5 Pb; 48 Bi, 28À5 Pb, 14À5 Sn, 9 Sb; 15 Sb, 58 Pb, 26 Sn, 1 Cu; 15 Sb, 82 Pb, 3 Sn.

Filed: 1972-12-18
Abstract: 1458813 Pile drivers T P AUMONIER 15 March 1974 [18 Dec 1972] 58407/72 Heading E1H A leader for a pile driver assembly comprises a helmet 10 having two spaced jaws 15, 16 integral with or rigidly connected to, a pair of frame members 20, 21 connected at their upper ends by a cross-member 26 and accommodating a drive hammer 13, at least one of the frame members having a rail 30 for slidably guiding the drive hammer. The leader may be lifted into position over a pile or piles by a crane, via a cable 14 attached to a pulley block 34. A second cable 36, attached at one end to the cross member at 38 passes over the pulley 35 and is connected at the other end to a tripping mechanism 39 slidably mounted on rail 30. When the leader is being raised, mechanism 39 engages an upper stop. When the jaws 15, 16 are secured to the top of a pile or piles by clamps 43, pulley block 34 is lowered until a pawl on mechanism 39 engages a catch on the piston of the hammer 13. The piston can then be raised to a predetermined height e.g. to initiate a diesel driver at which the pawl retracts, and driving commences. A latch 42 holds the mechanism 39 in a raised position. Anvil 17 transfers driving force to the pile or piles and may have a plastics dolly to avoid steel-steel contact between anvil and pile(s).

Abstract: 1366967 Semi-conductor devices TRANSISTOR AG 21 Dec 1972 [29 Dec 1971] 59270/72 Heading H1K At the upper surface 2 (Fig. 1a) of a bidirectional thyristor the N-type emitter region 9, together with an auxiliary strip 9<SP>1</SP> thereof, completely encloses an area 18 of the adjacent P-type region 7 containing a further isolated N- type region 11. The main electrode 13 contacts both the emitter region 9/9<SP>1</SP> and the P-type region 7 while the control electrode 14 contacts both the further N-type region 11 and the area 18 of the P type region 7. At the lower surface 3 (Fig. 1c) the N-type emitter region 12 includes a portion 12<SP>1</SP> whose outer periphery is of the same length and shape as the outer periphery of the auxiliary emitter strip 9<SP>1</SP> on the upper surface. The main electrode 15 contacts both the emitter region 12/12<SP>1</SP> and the adjacent P-type region 6. The various regions are arranged, as shown, symmetrically across a central plane S of the device. Preferably the parts of the P-type regions which are contacted are of relatively high conductivity. In the configuration shown the isolated N-type region 11 on the upper surface 2 is semicircular, there being an associated complementary semicircular P<SP>+</SP>-type zone 10. In a modification the region 11 is of half-ring shape, the P<SP>+</SP> zone then being shaped once more to complete a central circular area of the surface 2. Rectangular modifications of both these alternatives are also described.

Title: Electronic apparatus for thread cutting on copying machines of the electronically controlled type
IPC: H02P5/52
Filed: 1978-09-14
Abstract: An electronically controlled copying machine having a rotatable workpiece supporting mandrel and a tool holder carriage displaceable axially along a rotatable threaded shaft, is combined with an apparatus for enabling the production of single-start or multi-start threads. Angle sensors or synchros of the apparatus are driven by the rotatable mandrel and by the threaded shaft, through a selected gearing and interconnected electrically to derive a signal representing the relative angular displacement thereof. Speedometer dynamos are also driven by or with the mandrel and the threaded shaft and their signals compared to derive a signal representing their relative angular velocities. A calibration means generates a signal compensating for the initial relative angular displacements of the mandrel and the threaded shaft. The signals are combined in a summator circuit to produce a control voltage which is used to control the angular velocity of the threaded shaft to phase-relate the rotation of the mandrel and the threaded shaft.

Abstract: A permanent waving composition comprises from 0.03 to 0.06 mole of thioglycolic acid, from 0.06 to 0.12 mole of total ammonia, from 0.01 to 0.06 mole of free ammonia and from 0.01 to 0.06 mole of carbonate per 100 ml of the composition and has a pH of from 7.4 to 8.0 at 25 DEG C. This composition is applied to the hair at room temperature before, during and/or after winding the hair, and the hair is treated for from 5 to 30 minutes in an atmosphere having a temperature of from 40 to 60 DEG C and over-saturated with moisture, and the hair is hardened by oxidation. The composition remains stable at room temperature, but when heated releases carbon dioxide in the initial stage, raising the pH value and its ability to form waves. The volatilization of ammonia subsequently predominates, causing the pH to be reduced thus preventing overwaving or hair damage.

Filed: 1978-10-04
Abstract: A battery separator for controlling the charging current from a generator (1) to a parallel combination of at least two battery members (2, 3) which are capable of being loaded individually.
