Patent GB-1229610-A (GB)
IPC: G01N30/34
Filed: 1968-07-17
Abstract: 1,229,610. Electro-chemical analysis. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 17, 1968 [July 20, 1967], No.34080/68. Heading G1N. [Also in Division G3] Apparatus for measuring and supplying a controlled quantity of a gas utilises the reversible reaction of a "solid electrolyte" cell to absorb or supply gas according to the direction of the applied current. According to the invention the electrode on one face of the "solid electrolyte" is formed in two parts for measuring and supplying respectively. As shown an e.g. zirconium tube 11 has a spongy platinum internal electrode 12, and an external measuring electrode 13 and supply electrode 14. The measured signal is compared with a reference from potentiometer 16 and applied to amplifier 17 to energize the control electrode. TEMPERATURE COMPENSATION is provided by electrodes 19, 20 mounted outside the tube 11 to sense its resistance, and connected in a bridge circuit 21 to control a heater 15 in the outer casing. For controlling OXYGEN, a zirconium or thorium oxide tube is used with air as the reference gas: for HALOGENS a silver halide tube is used; for SULPHUR, silver iodide with a layer of silver sulphide thereon. APPLICATIONS:- sintering processes; maintaining given gas pressure in a vacuum system; removing last traces of oxygen from nitrogen; as a detector for a gas chromatograph by maintaining a constant small quantity of gas reactive with the effluent and metering the quantity generated Fig.4 (not shown). Improved control over a large range may be provided by non-linear elements, such as silicon diodes or Zener diodes, in the control circuit.

In a method of making a rigid pipe from at least one, spirally wound, continuous profiled band 4 of thermoplastic material having at least one longitudinally extending-channel and at least one longitudinally extending tongue 5 the band 4 is spirally wound, in a heated thermoplastic state, around a mandrel 1 so that the tongue engages in the channel, the channel being temporarily widened, or the tongue temporarily compressed, before being so engaged and finally cooled. As shown, the band 4 is fed between a plurality of pressure rollers 2, 2 and the co-operating rotatable mandrel 1, the band being guided by an element 9 on a wedging tool 8 which spreads apart the channel 6 before the rollers 2, 2 press it over the tongue 5. Cooling air is supplied between the rollers 2 through a pipe 3 the tool 8 being provided with passages which can supply solvents, hot air, &c., to the joint or, direct an additional soft band between the tongue 5 and the channel 6 before being bonded together. Instead of spreading the channel 6 the tongue 5 may be compressed, Fig. 4, not shown. Pipes having several overlapping band layers may be formed of bands having a plurality of tongues and channels, Figs. 8-10, not shown. The mandrel 1 is conically tapered at its take-off end, the angle of the rollers 2, 2 being adjustable with respect to the longitudinal axis of the pipe.

Abstract: 1,233,545. Semi-conductor devices. MULLARD Ltd. 2 July, 1968 [18 Aug., 1967], No. 38144/67. Heading H1K. The channel 24 of an insulated gate field effect transistor is bounded by portions 25, 26 of the source and drain regions which have been formed by ion implantation through the insulating layer 12 using the gate, source and drain electrodes 17, 16, 19 respectively as a mask. The width of the channel 24 is thus substantially equal to that of the gate electrode 17. In the Si device shown there are two channels 24 on either side of a common source region 6, 26. The major portions 6, 7 of the source and drain regions respectively are diffused, although relatively high energy ion implantation through a metal mask may alternatively be used, the preferred dopant in each case being boron. The electrodes 16, 17, 19 may, at the implantation stage, comprise parts of an integral layer of aluminium, which is subsequently selectively removed to leave only the electrode portions. This layer may be earthed during ion bombardment. The device is annealed at 500‹ C. after implantation. The insulating layer 12 may be of silicon oxide or nitride, or of superposed layers of oxide and nitride, and a phosphorus glass layer may be provided between the layer 12 and the gate electrode 17. The device described may be included in an integrated circuit including bipolar transistors, diodes, resistors and other insulating gate field effect transistors, parts of which devices may also have been formed by ion implantation.

Abstract: 1,250,233. Radiation dosimeters. EASTMAN KODAK CO. 5 March, 1969 [5 March, 1968], No. 11708/69. Heading H5R. [Also in Divisions B6 and G6] In the detection of nuclear particle radiation by a method employing the selective etching of the radiation-damaged portions of a radiation sensitive material, the material is first etched with a basic aqueous solution containing a swelling agent for the sensitive material, whereby the basic solution is permitted to attack the damaged portions more deeply. Preferably, the material is thereafter treated with a second basic aqueous solution containing a solvent for the material to repolish the undamaged surface portions, and thus both permit the radiation dose to be estimated by a photometric rather than a track-counting technique and also allow the use of a wider range of materials for the detector e.g. cellulose nitrate having a high content of plasticizing camphor. The radiationsensitive material may be cellulose nitrate, cellulose acetate, cellulose acetate-nitrate cellulose acetate-butyrate, or poly(ethleneglycol terephthalate); the swelling agent may be an alkali metal halide or thiocyanate, and the polishing agent may be ethyleneglycol or ethanol. The basic solution containing the swelling agent is caustic potash or caustic soda.
