Patent GB-877007-A (GB)
Title: Boring machines
IPC: B23Q1/62
Filed: 1958-10-31
Abstract: 877,007. Drilling. SULZER FRERES S.A. Oct. 31, 1958 [Nov. 2, 1957], No. 35060/58. Class 83 (3). In a drilling-machine with a laterally adjustable spindle 1, a first slide 6 is movable along a slideway 3 by a motor 9 and a second slide 5 carrying the drill-head 2 is movable, a shorter distance relatively to slide 6. As shown, slideway 3 is on a vertical column 7 adjustable horizontally by an electric motor 19 driving a pinion along a fixed rack 20. The drill-head also is mounted for horizontal movement, relatively to slide 5, on a guideway 50 on the slide, which is adjustable by a rack-and-pinion 13, 14 relatively to slide 6. A lever-and-spring device 15-17 or hydraulic means support slide 5 and the drill-head 2 from slide 6. Thus, electric-motors 9, 19 may position the drillhead approximately by moving the slides and column 7, fine adjustment in the vertical being effected by the rack-and-pinion 13, 14 and in the horizontal by means 25. The motors 9, 19 may be controlled by press-buttons 50 (Fig. 1, not shown), electronically or by potentiometers 10, 11 and 21, 22 co-operating with contacts 12 and 23 on slide 5 and the drill-head respectively. Movement of slide 5 relatively to slide 6 and thus of contact 12 relatively to the potentiometers 10 and 11, starts motor 9, causing slide 6 to move in the direction decided by slide 5. Similarly, movement of the drill-head by the means 25 effects movement of the column. Locks 26, 27 secure slide 5 and the drill-head after adjustment, which may be assisted by a drill-jig on the work. In a potentiometercontrolled modification, Fig. 3, the drill-head 31 is supported on a slide 30 by a spring 32, and slide 30 is movable horizontally on a guideway 37 on the vertical slide 29. Fluidoperated motors controlled by valves instead of potentiometers, may be used for moving the drill-head.

Title: Improvements relating to organo siloxane dispersions
IPC: C08J3/03
Filed: 1960-10-13
Abstract: The compositions of the invention comprise stable aqueous dispersions of one or more organosiloxanes, in which the one or more siloxanes are present as a constituent of a gel which also contains a gelling agent and which is dispersed in water containing an emulsifying agent.  The one or more organosiloxanes in the gel are preferably dissolved in or diluted by a solvent which preferably, is itself gelled by the gelling agent.  The dispersions containing solvents may be prepared by a process in which the solvent is heated with the gelling agent and stirred, to form a gel, additional solvent is added to replace that lost by evaporation, the one or more organosiloxanes are stirred in, and emulsifier and water are then stirred in to obtain the dispersion. The preferred gelling agents are metal soaps (e.g. an aluminium soap of a branched chain fatty acid of 6 to 8 carbon atoms) and the preferred emulsifying agents are alkylarylsulphonates. Solvents specified are perchloroethylene and a mixture of trichloroethylene and xylene.  The organosiloxane may be a silicone oil, resin or rubber.  Examples are given of the compositions in some of which mixtures of a silicone rubber and a silicone resin are used (3, 7 or 8).  Some of the dispersions are self-hardening.  The compositions may be used for coating or impregnating paper or textiles to render them resistant to water or adhesives, and as mould release agents.ALSO:Paper and textiles are coated to render them water repellant or adhesive resistant, with compositions (see Division C3) comprising stable, aqueous dispersions of one or more organosiloxanes which are present as a constituent of a gel which also contains a gelling agent and which is dispersed in water containing an emulsifying agent.  The gel may also contain a solvent which, preferably, is also gelled by the gelling agent. Curing agents for the organosiloxanes may also be present.ALSO:Paper and textiles are impregnated to render them water repellent or adhesive resistant, with compositions (see Division C3) comprising stable aqueous dispersions of one or more organo-siloxanes which are present as a constituent of a gel which also contains a gelling agent and which is dispersed in water containing an emulsifying agent.

Abstract: 448,463. Valves. WESLAKE, H., 11, Westleigh Avenue, Putney Hill, London. Dec. 8, 1934, No. 35351. [Class 135] [See also Group XXVII] In poppet valves, particularly for internal - combustion engines, of the kind having a hollow stem containing a sleeve or core of a metal having a better thermal conductivity than that of the valve, the sleeve or core is so con structed as to be readily collapsable to accommodate the diff erence in expansion of the two metals. Fig. 1 shows a valve 10 of steel fitted with a copper core 15 in the form of a sleeve with a longitudinal slot 19, which allows circumferential expansion of the sleeve so as to reduce radial enlargement of the valve stem. A space 21 is also left for longitudinal expansion. An iron spindle 16 is fitted closely within the sleeve 15, and both sleeve and spindle are formed with heads 17, 18 respectively, which are welded to the valve head. In a modification, the sleeve 15 is formed in two longitudinal halves, and the heads 17, 18 are replaced by separate discs welded in a flat recess in the valve head. Fig. 5 shows another form, in which the sleeve 15 is splayed out at the upper end to the shape of the valve, a cup-shaped recess 32 being formed in the head of the spindle 16. Or this spindle may be omitted, the sleeve 15 being partly filled with a material which becomes liquid when heated, such as sodium nitrate or metallic sodium.

Title: Process for the manufacture of semiconductor arrangements
IPC: H01L21/00
Filed: 1963-09-12
Abstract: A semi-conductor device is made by selective electrolytic deposition of metal from an alkaline bath containing the metal in the form of a complex on a 111 surface of a monocrystalline body of a semi-conductor compound crystallizing in the zinc blende lattice followed by alloying the metal to the body.  Deposition takes place only on <\>b1<\>b1<\>\b1 planes i.e. 111 planes at which there are free pairs of electrons e.g. in gallium arsenide the 111 planes containing only arsenic atoms.  In this way cadmium, copper, indium, silver and zinc may be deposited on the sulphides and selenides of zinc and cadmium and the arsenides, antimonides and phosphides of gallium and indium.  Cadmium, copper, indium, silver and zinc are preferably deposited from complex cyanide electrolytes but zinc, copper and tin may also be deposited from electrolytes in which the metal is complexed with ethylene-diamino-tetra-acetic acid. Suitable electrolyte compositions are specified. One or more other metals may be successively or simultaneously deposited on the electroplated 1<\>b1<\>b1<\>b surface.  Typically a diode is made by electrodepositing tin on the <\>b1<\>b1<\>b1 surface of a strip of dendritic N type gallium arsenide, overplating it with nickel and the rapidly alloying it to the strip.  Subsequently, while the 1<\>b1<\>b1<\>b surface with a removable varnish, zinc or nickel is electrodeposited on and alloyed to the opposite surface to form a PN junction.

Title: Frequency Discriminator
IPC: H04L27/156
Filed: 1966-08-12
Abstract: 1,155,455. Frequency discriminators. XEROX CORP. 12 Aug., 1966 [30 Aug., 1965], No. 36097/66. Heading H3A. In a facsimile receiver for receiving binary data 13 transmitted as sine waves 17 of one of two frequencies corresponding respectively to a binary one and a binary zero, means are provided for converting the signals into short duration pulses representative of zero crossings, the short pulses are integrated, and the integrated pulses are gated by the zero crossing pulses. In Fig. 1 the input signal 17 is squared in unit 23 and differentiated in unit 27 to produce pulses 25 of alternate polarities at instants corresponding to the zero crossings of the input signal. These pulses are transformed by recti fier 29 into unidirectional pulses 31 which are delayed in unit 33 for at least the duration of a pulse and then integrated in unit 39. The integrator 39 charges to a high level on receipt of a pulse and then decays, as shown at 41. If the interval between delayed pulses 37 is short, i.e. the input signal is of high frequency, the output of the integrator is high and is sufficient to pass through the gate 35 which is opened by the undelayed pulses 31. If the interval between pulses 37 is long, i.e. the input signal is of low frequency, the output of the integrator 39 is insufficient to pass through the gate 35. The output of gate 35 is therefore a sequence of pulses 43 corresponding to the high frequency (binary one) input signals, and these pulses are shaped and fed to output means. In a modification, Fig. 4 (not shown), the rectifier 29 and delay circuit 33 are omitted; the positive pulses in waveform 25 from the differentiator 27 are fed to the integrator 39 and the negative pulses in waveform 25 open the gate 35.

The latter have tapered rear portions 32, Fig. 8, to form a lead-in for the trays 17. The pivots 35 of the plates 34 have clamped thereto levers 37 which are connected by rods 38 to arms 39 adjustably mounted on a rocking shaft 40, the latter having clamped thereto a lever 43 terminating in a roller 45 which is in contact with an oscillating arm 46 of a vacuum feeder mechanism. The latter comprises two arms 46 on an oscillating shaft 47, Fig. 1, a square rod 48 extending between and being pivotably supported by the arms 46. Clamped to the rod 48 are arms 50 on which are mounted vacuum cup assemblies 49 which are movable between a vertical pickup position and a horizontal depositing position. Each vacuum cup assembly comprises a collapsible chamber 52 which upon collapse thereof retracts the mouth of the vacuum cup for pulling the foremost tray after it has been pried free of the lips 33 away from the stack 16. A vacuum line 53 extends from the vacuum cup assemblies 49 to a control valve (not shown) adapted to apply and relieve the vacuum at timed intervals. In a second embodiment, Fig. 11, the pronged plates 34 are replaced by separator elements 134, each of which has an elongated aperture 156 engaged by a pin 158 on a pivoted oscillating arm 159 for straight-line reciprocation of the element 134 in a guide 157. The sides 21, 22 of the advancing trays are deflected inwardly by a lead-in portion 132 of the retaining tabs 133. U.S.A. Specification 2,624,249 is referred to.

A main shaft 13 coupled to the vehicle axle and carries a cam 16 for actuating a pumping plunger 17. On the opposite side of the shaft is a locating plunger 21. Fulcrummed on a pin 23 on the inner end of the locating plunger is a rocking lever 24 having forked upper and lower ends which engage a pin 27 on the cam 16 and a roller 28 on the upper end of a second rocking lever 29 respectively. The lower end of the lever 29 lies between pins 33, 34 abutting respectively against the inlet and outlet valve 9 and 11. When the shaft 13 is rocked the lever 29 opens one or other of the valves 9, 11 to adjust the pressure in the suspension unit so as to maintain the chassis at a predetermined level. This level is determined by the position of the pin 23. The plunger 21 may be actuated to displace the fulcrum pin 23 and move the lever 29 to open the inlet valve 9 and thus the level of the chassis will be raised until the lever 29 has returned to the neutral position. The rocking lever 24 is locked against movement during the travel of the vehicle by spring loaded stop plungers 38 actuated by fluid pressure from the pumping plunger 17. A blow off valve may limit pressure applied to the plungers 38 and the pressure may leak away when pumping ceases.
