A cleat for use in joining together two members 12, 13 comprises two arms 2, 3 each provided with a pair of recesses 5, 8 one recess of each pair being located on one main face of the respective arm and the other reof each pair being located on the opposed main face of the respective arm, a tapped hole formed in each arm to interconnect the recesses of each pair, the tapped hole of each arm being inclined toward the other arm and intended to receive a screw 2'. In the construction shown the main face of each arm which is inside the angle has an additional recess 6 and another tapped hole joins this recess to a chamfered face 11 of the arm, the tapped hole containing a second screw 21. The two members 12, 13 to be joined together are each provided with a channel 20 defined by mutually spaced limbs 18, 19 the limb 18 being nearer The inner face of the joint and projecting further than the remote limb 19. The width of each channel is substantially the same as the distance between the inner and outer main faces 4 and 7 of the body and the limb 18 of each channel projects to at least the same distance as the width of each arm of the body; to join the members 12 and 13 together each arm is forcibly fitted into the corresponding channel 20 and the members 12 and 13 are pushed into mutual abutment along a mitre 14; the tapped holes 10 and 11 in each arm are exposed allowing the screws 21 to be inserted therein and on being tightened the screws 21 engage the limb 18 of each channel to force the members 12 and 13 together and also force the outer main face of each arm into contact with the limb 19. In a modification instead of the two arms being at right angles they can be aligned in which case the two members are joined together with a butt joint instead of a mitred joint.

Abstract: 273,571. B.S.A. Tools, Ltd., and Ogilvie, W. Dec. 9, 1926. Turning.-In automatic. turning and screwing machines of the kind wherein intermittently fed bar-stock is operated upon by a succession of tools carried by a turret, the turret having a step by step rotary movement and a slow traverse and quick return from operative engagement with the work, two tools are adapted to be brought alternately into operative position by oscillating the turret through the agency of two oppositely rotating cranks which are made to engage alternately with one of two slotted discs slidably keyed to the turret spindle. The turret 3 is fixed to a spindle 2 rotatably mounted on a slide 1 and having secured thereon a sleeve 9 with teeth 8 at one end on which is splined a sleeve 6 carrying two radially slotted discs 4, 5. A lever 25 engages an annular recess 28 in the sleeve 6 so as to bring one or other of the discs opposite to one of the cranks 31, 32 carried by the oppositely rotating bevel wheels 14, 15. The bevel wheel 15 is loose on the shaft 10 and the bevel wheel 14 is fixed thereon, both being engaged by a wheel 16 which is given an intermittent single rotation from an elongated pinion on the driving gear through one-revolution and stop gearing. A crank 12 on the shaft 10 operates mechanism which imparts a quick return movement to the slide 1. The lever 25 carries a bowl at one end which is actuated by a cam 20 rotated through two-to-one gearing 19 from the crank-shaft 10,- the bowl being mounted on a plunger 23 which may be maintained in a raised position on the lever to disengage the lever from the cam when the turret is not required to oscillate. To permit the turret to be rotated intermittently in one direction only a spring 39 is attached at one end to the lever and at the other end to either of the pins 40, 41 so as to maintain one of the discs 4, 5 in permanent engagement with the respective crank 31 or 32. The turret is locked by a spring plunger 33 which is retracted by a lever 34 and a cam 36 on the crank shalt 10.

Abstract: 324,967. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Oct. 27, 1928. Lubricants for fibres; soaps, materials and compositions for making.-An alkaline agent,. e.g. ammonia or alkali metal hydroxide, is combined, preferably in the presence of water, with a mixture of unsaturated acids made by splitting off water from the hydroxy-acid bearing oxidation products of high molecular compounds such as paraffin hydrocarbons or waxes, or from mixtures of these acids with their derivatives, e.g. esters, anhydrides or lactones, to form a lubricant for fibrous materials. Soaps are apparently made, but complete neutralization of the acids is not essential. Water may split off by distilling that part of the oxidation products which is insoluble in petroleum ether as described in Specification 322,487, [Class 2 (iii), Dyes &c.]. The oxidation step may be effected in liquid o,r gaseous phase, with a gas or mixture of gases containing or producing oxygen. In an example washed raw wool is treated with an emulsion in aqueous ammonia of the unsaturated acids made by distilling the hydroxy acids produced by oxidizing paraffin wax.

An arrangement for positioning accurately a head e.g. a proximity gauge 16, Fig. 4, of a measuring device comprises a support element 10 from one end of which a beam of radiation from a source 30 e.g. gallium arsenide is directed on to a detector 36 at the far end to set a datum line in the prevailing temperature conditions by adjustment of the source seating on a rubber O ring 29; an adjustable support 43 for the head whereby its position can be adjusted relative to the support element in a direction transverse to the direction of the beam; and radiation sensing means 45 arranged to sense when the sensing means and hence the measuring head are in a predetermined positional relationship to the beam. The head is mounted on a tube which can be moved longitudinally by rotation of a threaded portion 48 in its support and the sensor 45 and detector 36 each comprise split silicon detectors each connected in a differential manner to give null readings when the head is accurately positioned and the reference beam is set, respectively. The tube may be rectangular or square in cross-section and holed in a number of positions to receive the head support, blanking off plates being provided whereby the interior may be evacuated. The whole may be pivotally mounted and counter-balanced, and stop supports may be provided to set the operating position. The arrangement is suitable for plotting the contour of a rotatable drum 23 filled with steam in a paper tissue making machine. Dimensions and recording may be correlated by a cam driven by the rotating drum.

Abstract: 1,073,554. Transistors. HUGHES AIRCRAFT CO. July 23, 1965 [Aug. 18, 1964], No. 31499/65. Heading H1K. A planar semi-conductor device comprises a PN junction which terminates under an oxide layer, the surface adjacent P region being of lower resistivity and the surface adjacent. N region being of higher resistivity than their respective sub-surface regions. This avoids temperature-voltage dependent leakage which otherwise tends to occur at PN junctions terminating under oxide layers. A PNP transistor is produced by epitaxially depositing a P-type silicon layer 4 on a P-type 0À001 ohm cm., silicon substrate 2 and an N-type, 0À6 ohm cm. layer 6 is produced by diffusion of arsenic. This layer is covered with oxide with the central portion removed to allow further diffusion of N-type impurity to provide the N-type base zone 9 of the transistor. The exposed portions are then covered with oxide 8<SP>1</SP> which is partially removed to allow conversion of the remainder of layer 6 to low resistivity P-type region 4<SP>1</SP> leaving wings 9<SP>1</SP> of high resistivity N-type at the periphery of base zone 9. P-type emitter region 10 is also provided during this process. Ohmic connections are provided to base and emitter regions respectively by evaporating gold. Alternatively wires may be bonded by thermo-compression to base and emitter areas. The epitaxial deposition and diffusion may be interchanged and N-type layers may be provided by outdiffusion of excess acceptor material into an oxide layer.
