Title: Semiconducting compounds
IPC: C30B25/00
Filed: 1970-09-09
Abstract: 1316679 Vapour phase production of semiconductor materials SUMITOMO ELECTRIC INDUSTRIES Ltd 9 Sept 1970 [10 Sept 1969] 43139/70 Heading C1A Large single crystals of semi-conductor materials are prepared by a process described below with reference to gallium phosphide. A fused silica reaction tube 5 is divided into first and second temperature zones 16 and 17 by a quartz wall which has formed in it a thin silica tube 9. The temperatures within these two zones are controlled by means of furnace zones 2, 3 and 4 so that in the region of the first temperature zone where red phosphorous 10 is placed in a fused silica vessel 6, a low temperature (#430 C.) is maintained, and in the vicinity of the quartz wall a maximum temperature is maintained (1100-1200 C.), whilst a temperature gradient (#1100-950C.) is maintained in the second temperature zone from the quartz wall to the remote end of the zone. Red phosphorous 10 is vaporized at about 430 C. in the first temperature zone 16 and the vapour passes through the tube 9 into second temperature zone 17 where it reacts at about 1100 C. with molten gallium 11 in a fused silica vessel 7, forming a film of GaP 12 on the surface of the melt. The vapour of a carrier substance, GaI 3 , which is also present in second temperature zone 17, reacts with the layer of GaP to form GaI vapour and P 4  vapour which diffuse to the cooler end of the second temperature zone where they react to form crystalline GaP and GaI 3 . This re-formed GaI 3  then returns to the hotter part of the second temperature zone by reason of the temperature gradient where it can react further with GaP formed on the gallium melt and continue the formation of a large single crystal of GaP. The rate of growth of the crystal can be increased by slight movement of the furnaces 2, 3 and 4 from right to left in the sense of the drawings. The object of the thin silica tube and maximum temperature zone is to permit the passage of P vapour from the first to the second temperature zone whilst preventing diffusion of GaP and GaI in the opposite direction. Semi-conductor materials which can be obtained by the method of the invention include GaP, InP, AlAs, AlP, Ga 1-x Al x P, Ga 1-x Al x As, In 1-x Ga x P, In 1-x Al x P, InAs 1-x P x , ZnTe, ZnTe 1-x  Se x , ZnSiP 2 , ZnGeP 2 , ZnSiAs 2  and Cd 3 P 2 , where 0#x#1. Such semi-conductor materials may be used in solid state optical devices and functional devices. Suitable transport substances include I 2 , GaCl, GaBr, GaBr 3 , GaCl 3 , H 2 O, InI 3 , InI, InBr 3 , InBr, InCl 3 , InCl, PbCl 2 , PbBr 2 , PbI 2 , PI 3 , ZnCl 2 , CdCl 2  (these last 2 give p-type GaP) SnCl 2 , TeCl 4 , TeBr 4 , SeCl 4  which give n-type GaP crystal.

Title: Process for the preparation of dicarboxylic acids
IPC: C07C51/31
Filed: 1964-10-26
Abstract: Saturated aliphatic dicarboxylic acids are prepared by a continuous method comprising oxidizing a cycloalkane having 5 to 12 ring carbon atoms with aqueous nitric acid in the liquid phase in the presence of a "vanadium catalyst", the steady state conditions of the reaction being 75 to 130 DEG  C.; 40 to 1000 p.s.i.g.; the presence in the organic phase of the reaction mixture of 10 to 97% by weight, of the organic phase, of a mono- or di-nitrohydrocarbon and/or a nitrocarboxylic acid or a nitro compound which is a precursor for such an acid and which is readily oxidizable thereto under the steady state conditions; a concentration of nitric acid of 35 to 80% by weight of the aqueous phase and the presence of a molar excess of nitric acid with respect to the cycloalkane.  In a preferred embodiment a "copper catalyst" is employed together with the "vanadium catalyst". The organic nitro-compound may be a nitrocycloalkane derived from the cycloalkane to be oxidized, whence it is possible to reduce the net yield of nitrocycloalkane to zero if desired.  The reaction may be effected in an atmosphere containing nitrogen and also molecular oxygen or air to reduce the risk of explosion and to reduce the total amount of nitrogen oxides produced. "Vanadium catalyst" is defined to mean a vanadium compound capable of introducing vanadium-containing ions into the reaction mixture and "copper catalyst" is defined to mean metallic copper or a copper compound capable of introducing copper-containing ions into the reaction mixture.

Filed: 1972-09-22
Abstract: 1410177 Anti-skid brake circuits AISIN SEIKI KK 22 Sept 1972 [25 Sept 1971] 44075/72 Heading F2F An anti-skid control circuit comprises a wheel deceleration sensor 9 which generates first and second electrical signals corresponding to two predetermined wheel deceleration values, the first signal actuating a first pneumatic selector valve 60 to connect, with a pressure source, first chambers 31, 51 of first and second pneumatic servomotors 30, 50 respectively having spring loaded diaphragm pistons 32, 52, the first servomotor having a smaller area piston or a lower spring loading to operate before the second servomotor to actuate a cut-off valve 20 in an hydraulic master cylinder brake circuit, the second servomotor then actuating an hydraulic capacity control device 40 in the brake circuit; the second signal actuates a second pneumatic selector valve 70 to provide a further connection between the first chambers of the servomotors and the pressure source during actuation of the first selector valve 60, a control valve 80 being disposed within a communication passage between the first selector valve and the first chamber of the second servomotor to decrease the flow-through area between the selector valve and the chamber 51 in response to initial movement of the piston 52. The brake master cylinder 1 controls a vehicle's front wheel brakes 7 directly and the rear wheel brakes 3 via the cut-off valve 20 and the capacity control device 40. The first signal from the sensor 9 in response to a lower wheel deceleration value actuates a solenoid controlled spring returned spool valve member 64 to open communication between the pressure source 12, a chamber 68, a passage leading to holes 84 opening into the second servomotor first chamber 52, and from there to the first servomotor first chamber 52 via a line 37. Communication is closed between the chamber 68 and a chamber 69 open to a vacuum source 10 which communicates with the second chambers 35, 55 of the servomotors. Upon movement of the piston 52, a rod 43 causes an increase in volume in the brake circuit to lower the brake pressure; in addition, the control valve 80 closes holes 84 and only allows small inflow via an orifice 77 to the chamber 51. If a higher wheel deceleration value is attained during this, a solenoid controlled, spring returned tubular valve member 72 opens further communication from the chamber 68 to the chamber 51 via a hole 75 for further piston movement to cause further brake pressure decrease.

Title: Improvements relating to knitting machines
IPC: D04B15/78
Filed: 1964-11-06
Abstract: Needle selection is achieved in a circular machine by having jacks (13) which can be raised by springs (14) when the jacks are released by spring bars (16), Fig. 1 not shown and, as described in Specification 992564, the bars (16) are selectively operated to release the jacks by being influenced by a magnet.  In the present invention the magnetic arrangement for influencing the bars includes a soft iron pole shoe which is surrounded by a solenoid winding so that energizing the solenoid controls the magnet to vary the magnetic field of force of the pole shoe to weaken, compensate or reverse the polarity of the field and the arrangement may take various forms. For example, the soft iron pole shoes (31, 32) of a permanent magnet Figs. 4 and 4a, not shown, may have one or both shoes partly divided and one part of each shoe surrounded by a coil which when energized so influences that part of the shoe to cause the magnetic effect so produced to release the spring bar (16) which has been deflected by the cam (35) prior to the jack being raised by the spring (14).  The coil is supplied with current at such periods as will cause each bar (16) to be held or released by the pole shoes in turns.  A sapphire stone (33) is positioned between the pole surfaces (31C, 32C) to provide a bearing surface for the bars (16). Alternatively two bar magnets may be provided to influence three pole shoes and the control pole shoe is partly surrounded by the coil and is similarly operated to effect the bar selection. Instead of the ends of the pole shoes providing the bearing surface for the bars (16) a cylindrical member may be provided against which the pole shoes bear to induce polarity into the various parts of the member.  The member has a flat surface provided against which the bars bear and to ensure proper engagement with the bars the cylindrical member can be rotatably adjusted.
