Abstract: 1,266,705. Friction welding. CATERPILLAR TRACTOR CO. 22 Sept., 1969 [20 Nov., 1968], No. 46621/69. Heading B3R. A method of inertia friction welding a first workpiece 29 to a second workpiece 38 so that the joined workpieces are precisely orientated comprises fixedly holding the second workpiece 38 against rotation whilst the other, 29, rotates and bringing them together to produce frictional heat and then at a predetermined stage releasing the second workpiece to join to and rotate with the first in a predetermined aligned orientation. The workpiece 29 and indicator means 28, 34 are aligned initially and are aligned with workpiece 38. A motor 15 rotates the spindle 21 carrying the workpiece 29 and inertia weights 31, 33 via hydraulic pump 17 and hydraulic motor 19 and the power is discontinued at a predetermined velocity. At the same time the second workpiece 38 is moved into contact with the rotating workpiece 29 by an hydraulic ram assembly 23, the pressure of which simultaneously actuates a timing device 43. The timing device 43 after a predetermined time then energizes a pick-up 36 to monitor the position of the spindle 21 by an indicator means 34 which is aligned with a similar means 28, to thus signal the release of the fixed workpiece 38 by release of a brake 41 when the indicator reaches a predetermined position. The workpiece 38 then reaches the speed of the rotating workpiece 29 and the weld is complete. Allowance has to be made when timing the release of the brake 41 to account for the time taken for the speeds of the workpieces to be the same. A control may be provided to carry out actuation of the force transmission assembly and then to provide fluid pressure to the hydraulic ram assembly 23 via a valve and when the welding process is finished to provide pressure via another valve to retract the ram.

Abstract: 1327392 Cathode-ray storage tubes; semiconductor devices EMI Ltd 13 Nov 1970 [8 Oct 1969] 49523/69 Headings H1D and H1K A charge storage target plate comprises a mosaic of rectifying junctions which are barrier junctions formed on the surface of a semiconductor substrate. The substrate is preferably germanium but may be of silicon, indium antimonide or indium arsenide, on which is deposited an array of gold islands separated by silicon oxide; preferably a layer of gold of resistance 10<SP>13</SP> ohms./square is deposited over the mosaic to provide a leakage path. The opposite side of the substrate is coated with a metal such as aluminium, antimony, or a gold/ antimony mixture to reduce surface recombination of charge carriers. An aluminium layer may be coated with magnesium fluoride to prevent oxidation prior to insertion in a pick-up tube; if the latter is for use with infra-red light the thickness of the magnesium fluoride should be chosen to maximize transmission and minimize reflection at near infra-red frequencies. Electrode processing.-A sheet of germanium is lapped, polished and etched to a thickness of 1À5 thousandths of an inch. A thin sheet of gold is evaporated on to it and coated with a photo-resist which is exposed through a mask and the unhardened part dissolved. Unprotected gold is etched away in a solution of potassium iodide and iodine and the hardened photo-resist is stripped off to leave islands of gold. A layer of silicon oxide is evaporated over the mosaic and annealed; this layer is coated with a photo-resist which is exposed through a mask, and unprotected silicon oxide is dissolved in a solution of ammonium chloride and hydrogen fluoride in de-ionized water to leave insulating regions between the gold contacts of the mosaic (Fig. 1j, not shown). A thin layer of gold is evaporated over the mosaic, and aluminium is evaporated over the other side of the substrate to a thickness controlled by a resistance monitor so as to provide an N+ layer and is coated with magnesium fluoride. As an alternative process silicon oxide may be evaporated on to the germanium and holes formed in it by a photoresist process; gold is evaporated overall and channels are etched into the gold to leave gold islands in contact with the germanium surface and overlapping the surrounding silicon oxide.

Abstract: 1343598 Gyroscopic apparatus FERRANTI Ltd 2 June 1971 [6 March 1970] 10956/70 Heading G1C An inertial guidance system for fighter aircraft based on a ship, wherein each aircraft has a three-axis inertial platform, includes ship-located reference equipment incorporating a reference inertial platform and means for deriving signals therefrom to represent orthogonal components of the ship's velocity and acceleration at the reference platform. As shown reference equipment 12 on the ship's deck-11 comprises a casing 13 within which is a reference platform 14 employing three singleaxis gyros and two linear accelerometers. Apparatus is also included for deriving signals to represent the N-S and E-W components of acceleration and velocity at the platform, resolved in a plane in which the platform is levelled. The casing supports a sighting mark 21, so as to be visible to each pilot through his head-up display when in position for take-off, and a telescope 22 for determining the bearing of mark 21 as viewed from each aircraft and the range R of the aircraft from platform 14. The telescope can be brought to bear on each aircraft in turn. One such aircraft 23 has an inertial platform 24. The reference equipment embodies a computer 27. The latter includes a resolver 34 whose outputs are R cos # cos #<SP>1</SP> and R cos # Sin #<SP>1</SP> which are the N-S, E-W components of R in the plane of platform 14. (e is the elevation of the sighting line 72 from the aircraft to telescope 22 above the plane of platform 14; # is the bearing at the reference equipment of the aircraft and #<SP>1</SP> = # + 180) An electronic stage 41 provides outputs representing the ship's velocity at platform 14, suitably resolved, and ship's acceleration, suitably resolved. Both sets of outputs are combined with the respective outputs from resolver 34 after there first and second order time derivatives have been taken. The computer 27 is connected to the aircraft navigation equipment by cable 66 and snatch plug 67. Thus inputs to the aircraft electronic stage 65 constitute computed values of velocity and acceleration at the site of the aircraft. These data are used to effect, firstly, coarse and, secondly, fine levelling of the aircraft's platform 24. Subsequently the platform 24 is oriented so as to head north. During this procedure the pilot rotates the output axis of the azimuth gyro to rotate platform 24 until the aiming line of his head-up display bears on sighting mark 21, this condition being reached when the platform 24 is correctly oriented. Where the reference platform is approximately level with the aircraft, # may be taken as zero, in which case the outputs from resolver 34 are R cos #<SP>1</SP> and R sin #. Additionally, the first order differentiating stages may be abandoned in favour of differentiation prior to resolver 34. Specification 1274789 is referred to.
