Abstract: 844,296. Borehole apparatus. EDWARDS BUILDING SERVICES PTY. Ltd. Nov. 21, 1958 [Dec. 6, 1957], No. 37615/58. Class 85. A bucket adapted to be attached to an auger shaft and lowered into a hole cut by a standard auger has extending cutters which enlarge the bottom of the hole. The bucket 10 has a boss 12, with a square hole in it, mounted on the beams 11. Sliding in the boss is a square shaft 14, the movement of which is limited by a pin 19 running in slots 20 in the bush. The shaft 14 has an extension of circular cross-section which reaches nearly to the bottom of the bucket, is contained within a hollow shaft 15 which extends to the bottom of the bucket, and is supported at its upper end by a bearing 16. The shaft 15 is free to rotate relative to the bucket, but vertical movement is prevented by two collars 18. The bucket is supported by the pin 19 while being lowered into a hole but when it strikes the bottom of the hole, the shaft 14 moves down and projecting pins 21 move along spiral slots 22 in the hollow shaft 15 and turn it. As the shaft 15 turns a cross-beam 23 secured to it operates two links 25 which extend the cutters 26. In a modification (Fig. 6) the linkage for the cutters comprises a square shaft 114 which can move vertically, but not rotate, relative to the bucket 110. When the bucket strikes the bottom of the hole the links 125 move from the dotted line position to the full line position and extend the cutters.

Title: Improvements relating to transistors
IPC: H01L21/48
Filed: 1957-12-03
Abstract: 873,485. Transistors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 3, 1957, No. 37657/57. Drawings to Specification. Class 37. A method of manufacture of a transistor having a N-type silicon base with emitter and collector zones diffused from aluminium wire electrodes and the emitter smaller than the collector, comprises soldering in a reducing or inert atmosphere a base to a plate of N-type silicon using a solder such as an alloy of gold and antimony (0.6 to 1% antimony) or a goldlead alloy containing a trace of arsenic (0.1%), the alloy being initially in the form of a thin sheet. The collector junction is formed by melting the end of a pure aluminium wire of diameter about 1 mm. to the centre of the semi-conductor the wire having been chemically cleaned and protected against oxidation by immersion in an organic liquid such as acetone. The emitter junction is formed by electrolytically tapering a fine aluminium wire (100 microns diameter) using for example perchloric acid and acetic acid the point being placed in contact with the face of the semi-conductor opposite, and centrally disposed to, the collector region. The junction being formed by passing a short pulse of current through the emitter electrode to the base, fusing the aluminium and silicon and forming the emitter zone. Preferably the area around the emitter junction is heated to 300‹ C. whilst the junction is formed. Electrolytic cleaning of the assembly is used and the transistor is enclosed in an envelope. Specification 816,170 is referred to.

IPC: A63B53/10
Filed: 1973-08-08
Abstract: 1446444 Golf club shafts ALDILA INC 8 Aug 1973 [27 April 1973] 37664/73 Heading A6D A tapered tubular golf club shaft having uniform wall thickness includes superposed carbon fibre layers, the fibres being helically arranged in at least one of the layers, some of the fibres in each layer extending from end to end of the shaft, all the fibres of all the layers being embedded in and bodned together by a plastics, e.g. epoxy material. Each layer may comprise a slightly-tapering strip, cut from a preformed tape of parallel carbon fibres impregnated with thermo-settable epoxy resin. Four such strips are helically wound on a tapered mandrel, adjacent layers being of opposite hand. A fifth layer of fibres extending along the shaft axis is applied and is followed by four more helical layers and a final longitudinal layer. During assembly of the layers, intermediate compression steps, involving both the rolling of the covered mandrel between relatively reciprocating parallel platens and the application and subsequent removal of tape wound under tension, are carried out. The assembly of layers is covered by a wrapping of aluminium foil and then a tape, helically wound under tension. The covered mandrel is then heated in an oven to cure the resin. The helically wound tape, the aluminium foil and the mandrel are then removed. The outer surface of the shaft is finally ground and given two coats of polyurethane paint. A wooden club head may be secured to the shaft by epoxy adhesive, and the region of the join may then be wrapped, Figs. 1-4 (not shown).

Title: Stroke counter
IPC: G06M1/16
Filed: 1957-12-03
Abstract: 813,738. Counting-apparatus. PALIZ-HOLDING A.G. Dec. 3, 1957 [Dec. 19, 1956], No. 37668/57. Class 106 (1). A mechanical stroke counter in which the lowest order numeral wheel is driven by a ten point star-wheel has a shaft on which is mounted a member which when the shaft is rotated in one direction rotates the star-wheel to effect subtraction of one unit in the lowest order and when the shaft is rotated in the other direction effects zeroizing of the counter by means of heart-shaped cams attached to the numeral wheels. The frame 4 bears a shaft 3 carrying numeral wheels 5, 6, 7 with counterweights such as 6b to balance the zeroizing cams, an actuating shaft 1 and a zeroizing shaft 2. A force on the end 1a of the shaft 1 revolving the shaft in a clockwise direction (Fig. 4) against the action of a spring 12 causes a spring 14 to move an actuating bracket 10 so that a prong 10e moves a star-wheel 5c attached to the lowest order wheel 5 through just over half a step, the remaining one-tenth revolution being completed on the return movement by the prong 10d, a brake spring 15 preventing undesired rotation of the wheel 5. The shaft 2 and associated handle 2a are yieldingly held by a spring 16 and bracket 17 and if the shaft is rotated in a clockwise direction (Fig. 4) until the end 18a of a pin 18 in the shaft 2 abuts the end of a slot 19a in the pinion carrier bracket 19, a bracket 22 is rocked by the lower end 18b of the pin 18 so that its nose 22b engages the star-wheel 5c which is thereby turned back for just over onehalf a step causing the nose 10d of the actuating bracket 10 to retreat and snap into the subsequent tooth gap thereby completing the onetenth revolution step back on release of the star-wheel 5c by the nose 22b of the bracket 22. During this process the pinion carrier 19 rocks in a clockwise direction until the shoulder 19b meets the shaft 3. Zeroizing.-To reset the counter to zero, the shaft 2 is rotated in a counter-clockwise direction against the action of the spring 16. The bracket 22 is rocked in a counter-clockwise direction by the action of the spring 23, one end of which abuts the lower end 18b of the pin 18, the other end being inserted in a hole 22c in the bracket 22. When the upper end of the slot 22d, Fig. 2, abuts the nose 19d, the pinion carrier 19 is rocked against the action of the spring 20 to disengage the pinions 8, 9 from the teeth 6c, 7c of the numeral wheels 6, 7 which are then returned to zero by fingers such as 22f engaging the heart-shaped cams such as 6a attached to the numeral wheels. In a modification the brake spring 15 may be replaced by a star-shaped plate spring interposed between the numeral wheels 5 and 6. In another modification (Figs. 10 and 11, not shown) curved plate springs mounted on the shaft 3 are inserted between the end numeral wheels and the pinion carrier 19 and serve to press the numeral wheels together.

Abstract: 377,072. Interrupters. BOSCH AKT.-GES., R., 4, Militõrstrasse, Stuttgart, Germany. Dec. 5, 1931, No. 33772. Convention date, Dec. 19, 1930. [Class 38 (v).] In a double ignition interrupter in which two separate interrupters are operable alternatively, one interrupter acting as a reserve for the other, in order to put one of the interrupters out of action, rocking levers which are relatively displaced on the periphery of the cam are arranged to be turned by an arrangement of levers so that one of the interrupting levers is brought out of the range of operation of the cam. As shown in Fig. 1, two pivoted interrupting levers 10, 11 are arranged at different points around an operating cam, being pivoted on pins 12, 13 and provided with springs 14, 15 which are extended to form curved operating projections 16, 17. The insulating blocks forming the interrupter levers are provided with slots 22, 23 into which project upturned projections 20, 21 formed integrally with links 18, 19 also pivoted at 12, 13 and connected by a member 24 which has an upstanding projection 25 formed with a slot 26, Fig. 3. Into the slot 26 projects a cranked projection 27 of a change-over knob 28. This knob has a bar 35 held in a recess at the end of its range of movement and when the knob 28 is moved between its extreme positions the bar 24 is thereby swung across so causing one or other of the operating projections 16, 17 to be swung out of the range of the operating cam. The two interrupter levers are arranged as shown in Fig. 3 at different points along the axis of the operating cam so that when either of the interrupter levers is moved into operative engagement with the cam it wipes over a different track thereon to that engaged by the lever previously in use. This axial displacement is provided for by cranking the arm 24 at one end 37 and providing packing pieces on the pivot pin 12 between the arm 18 and the interrupter base.

Title: Improvements in or relating to variable electrical equalisers
Inventor: CAMERON WILLIAM ALFRED
IPC: H04B3/14
Filed: 1959-11-11
Abstract: 903,691. Variable equalizers. GENERAL ELECTRIC CO. Ltd. Nov. 9, 1960 [Nov. 11, 1959], No. 38241/59. Class 40 (4). In a variable equalizer of the type comprising two impedances the product of which is required to be kept constant, these impedances are connected in the arms of an almost balanced bridge or like circuit one of the impedances being controlled by the unbalance current of the bridge. As shown, the equalizer consists of a T-network 7 whose shunt arm is connected to a network 12 terminated by a thermistor 13, and whose series arms are shunted by a further network 11 terminated by a further thermistor 14, of the type described in Specification 508,341. The thermistors 13, 14 which have negative temperature coefficients are contained in opposite arms of a Wheatstone bridge 20 whose diagonals form the input and output of an amplifier 34, 35, the bridge being arranged to be slightly out of balance to produce sufficient feedback to cause the amplifier to oscillate at a frequency (5 kc/s.) low compared with the signal currents. When a control current applied to terminals 5, 6 changes in such a way as to increase the resistance 13 the bridge becomes more out of balance to increase the amplitude of the oscillation, which oscillation after amplification by transistor 48 controls the heating of the thermistor 14 to decrease its resistance. Filters 52, 53, 54, 55 prevent the oscillator current from entering the signal path and the signal current from entering the bridge circuit. In a modification the bridge is energized by D.C., the out-of-balance D.C. current being used to control amplification means for providing heater current to the thermistor 14. Such means may comprise an oscillator having a modulator in the feedback circuit controlled by the out-of-balance current as described in Specification 873,786.
