Title: Method of making an electrically conducting glass structure
IPC: C03C17/25
Filed: 1957-08-12
Abstract: An electrically conducting glass unit is produced by applying spaced electrodes to the surface of a glass sheet, heating the sheet to approximately its softening point, spraying the electrodes and at least the adjacent part of the surface of the heated glass that carries the electrodes with a phosphate-containing solution and thereafter spraying the heated sheet and the electrodes with a solution of a metal halide to form a metal oxide film thereon.  The phosphate-containing solution may be phosphoric acid dissolved in isopropanol, or may be a solution of an organic or inorganic phosphate.  The metal halide may be stannic chloride.  The electrodes may be produced by firing on a mixture of silver, flux, organic binder and thinner.

Title: Improved Thermionic Detector for Gas Chromatography
Inventor: DIMICK KEENE PAUL
IPC: G01N30/68
Filed: 1967-06-01
Abstract: 1,160,828. Gas analysis. VARIAN ASSOCIATES. June 1, 1967 [June 6, 1966], No.25410/67. Heading G1N. Effluent gas from a chromatographic column is mixed with hydrogen and the mixture is burnt in air at the upper surface of a homogeneous ion source block 29 so that the heat of the resulting flame can ionize material from the surface of the ion source to introduce charged particles into the space between electrodes 32, 34. The ion source block 29 preferably consists of a salt of an alkali, or alkaline earth, metal (examples given) containing 2 to 5% refractory binder, e.g. silica. In the presence of an organic constituent containing phosphorus or a halogen, the rate of ionization of material from the ion source block is increased. The relative sensitivity to phosphorus and halogens depends on the air and hydrogen input flow rates so that by proper adjustment of the flow rates, the detector can be made virtually insensitive to halogens, responding only to phosphorus. A bucking voltage is used to oppose the effect of ions produced in the absence of phosphorus or a halogen. Electrode 32 also serves as an ignition coil.

IPC: H01L29/00
Filed: 1965-06-17
Abstract: 1,100,708. Semi - conductor devices. WESTERN ELECTRIC CO. Inc. 17 June, 1965 [23 June, 1964], No. 25617/65. Heading HlK. In a device having a metal-to-semi -conductor rectifying junction, the metal layer consists of two different metals in contact with each other, both contacting a surface of the semi-conductor. The metal having the lower barrier potential defines the effective junction and the other metal provides a contact area for an electrode lead. In Fig. 1, an N-type silicon wafer 11 has been provided-eg. by vapour phase deposition through a surface oxide mask-with an annular deposit 12 of platinum which may, but need not, be alloyed to the silicon. The platinum serves as a mask for deposition of a circular layer 13 of tungsten inside the platinum annulus. An electrode lead 14 is attached, e.g. by thermocompression bonding, to the platinum and an ohmic contact 15 is made to the opposite face of the wafer, thus completing a diode in which the metal electrode connection is to the platinum, the junction effectively being that between the tungsten and the silicon. If the silicon is P-type the roles of platinum and tungsten are reversed. The invention may also be applied to germanium and gallium arsenide semi-conductors. The platinum may be replaced by gold or vanadium and the tungsten by molybdenum, silver or copper. The lower barrier metal may also be of calcium, magnesium, lithium or sodium provided that the higher barrier metal, to which the electrode lead will be attached, completely covers and protects it from the atmosphere. In Fig. 2 (not shown), a diode differing from that described above only in that the metal layers are contiguous rectangles has been converted into a metal base transistor by deposition on the metal layer constituting the effective barrier of further semi-conductor material, which need not be the same semi-conductor as the underlying wafer.

Abstract: 138,310. Universelle Cigarettenmaschinen-Fabrik, J. C. Muller & Co. Jan. 25, 1919, [Convention date]. Paper tubes. - In a cigarette-tube-making machine means is provided for regulating the length of the mouth-piece sheets cut from a paper strip advanced intermittingly by a pair of rolls e, f to a coiler d. To effect this regulation, the rolls e, f are operated by a toothed sector h integral with a bell-crank lever i which is oscillated by a slotted swinging arm p pivoted to an arm t and operated by a connecting-rod r and crank s. The sector h oscillates a wheel g, which by means of a free-wheel device rotates the rolls e, f intermittingly. The lever i is pivoted to a block n, which can slide in the slotted arm p. To adjust the length of sheet fed to the coiler d, the lever i, rolls e, f, and cutters b are all carried on an adjustable table c, and, by adjusting the position of the table, the block n moves in the slot o and the extent of the intermittent feed is varied. Alternatively, the cutters b, and the arms p, t, may be movable relatively to the lever i and rolls e, f. In this case, the cutters b and the pivot of lever p axe mounted on slides movable by right and left hand threads on a common actuating-shaft. In either case, the adjustment can be effected during the working of the machine, and it is possible to ensure that the outer edge of the mouth-piece on insertion into the cigarette paper tube comes in line with the seam of the said tube.
