Title: A Process for the Production of Metal Coating Connections in a Semiconductor System
IPC: H01L23/485
Filed: 1967-08-25
Abstract: 1,163,463. Semi-conductor devices. ROBERT BOSCH G.m.b.H. 25 Aug., 1967 [26 Aug., 1966], No. 39207/67. Heading H1K. [Also in Division C7] A coating of Ni in a specific pattern is formed on a semi-conductor of Si in a process comprising applying a photo-resist to the specific pattern on the oxide coated Si surface, etching away the exposed areas of oxide coating, removing the resist, vapour depositing Ni, annealing to form a coating of nickel silicide and removing the Ni deposited on the unetched portions by dissolution in an acid such as HNO 3  or a mixture of HCl or H 2 O 2  As shown in Fig. 1 a photo-lacquer layer 3 was applied to a Si disc 1 having a SiO 2  layer 2. A photo-mask 4 was applied and the disc exposed to ultra-violet light and then treated in a photographic developer. Etching with aqueous HF buffered with NH 4 F was then carried out and the remaining photo-lacquer was dissolved in H 2 SO 4  or an organic solvent. After vapour deposition of Ni under vacuum, annealing is effected at over 600‹ C. followed by dissolution of the remaining Ni. The annealed coating is etched in aqueous HF buffered with NH 4 F and Ni electrodes are deposited from a solution of NiCl 2  and NaH 2 PO 2 .

The liquid or paste is formed by melting the detergent or adding water or other volatile solvent to the detergent. The granules are produced by spray-cooling or spray-drying fluid dispersions of active ingredients, or by plodding pasty dispersions. A hydrotrope such as an alkali metal or ammonium salt of a C 1 -C 5  alkyl benzene sulphonic acid may be present. The builder may be inorganic (e.g. sodium tripolyphosphate) or organic (e.g. sodium nitrilotriacetate). Optional ingredients are bleaches such as sodium perborate and other conventional constituents of washing powders in which the enzyme granules may be incorporated.

An air inlet 7 leads to the space between inner and outer casings 4, 8, from which space air is admitted to the gases in chamber 9 through perforated tubes 17. Ignition means may be provided in chamber 9. In a modification, Fig. 6, the chamber is oval in cross-section and the alternate passages 27a, 27b, through which the gases flow to and from the combustion chamber extend around the combustion chamber 26.

Title: Improvements relating to regulating arrangements for gaseous electric discharge devices
IPC: H01J17/26
Filed: 1957-12-19
Abstract: 868,061. Temperature control of discharge devices. COMPAGNIE FRANCAISE THOMSON-HOUSTON. Dec. 19, 1957 [Jan. 22, 1957], No. 39521/57. Class 40 (1). [Also in Group XL (a)] The source of heating current for the heater element of a gaseous electric discharge device contains means responsive to variations in ambient temperature to modify the heating current accordingly. The heater element is in heatexchange relationship with material containing absorbed gas so that variations in ambient temperature cause this material to liberate or absorb gas from the atmosphere within the envelope of the discharge device and thus nullify variations of pressure due to the ambient temperature changes. In Fig. 1 the heater is supplied from a constant-current source 8 (or a voltage source with series resistor). The heater element 3 is surrounded by a hollow member 4 having walls of a material capable of absorbing hydrogen, e.g. titanium, zirconium, cerium, thorium, vanadium or tantalum, and is connected to the source via a thermistor 2. Outside the envelope are a further thermistor 9 and (optional) series resistor 10. When the ambient temperature varies, the thermistor 9 takes more or less current and the heating current through 2 or 3 therefore decreases or increases respectively. The walls of the hollow member 4 then absorb or liberate hydrogen to maintain constant the pressure in the envelope. In a modification (Fig. 3, not shown) the circuit outside the envelope comprises only a voltage source in series with a resistor having a high positive temperature coefficient.

Title: Improvements in or relating to coating metallic bases with metals by the decomposition of gaseous metallic compounds
Inventor: DRUMMOND FOLSOM E
IPC: C23C16/54
Filed: 1958-12-10
Abstract: Before being coated with metal by the thermal decomposition of a gaseous metal-bearing compound, a continuously moving metal base is heated and subjected to sub-atmospheric pressure in order to degasify it.  In the specific embodiment, a metal strip (e.g. of steel, aluminium or copper) is cleaned, dried by a hot air blast, and then passed through three chambers in which it is respectively heated, subjected to sub-atmospheric pressure (e.g. in an atmosphere of nitrogen, helium or carbon dioxide), and coated with metal.  The coated strip may then be optionally heat-treated. Thermally decomposable metal compounds which may be used are carbonyls e.g. of nickel, iron, chromium, molybdenum or cobalt; cobalt nitrosyl carbonyl; osmium carbonyl bromide or ruthenium carbonyl chloride; copper nitroxyl; antimony hydride or tin hydride; chromyl chloride; and metal alkyls.

Abstract: 935,265. A.C. motors. REGULATOR A.G. Nov. 13, 1961 [Nov. 15, 1960], No. 40454/61. Class 35. In a rotary A.C. motor the rotor carries at least one winding connected in a closed circuit which includes a unidirectionally conductive element 29, and the stator 15 for co-operating with the winding comprises two separate magnetic systems which respectively create alternating and unidirectional magnetic fields. As shown, the winding comprises ribs 17, 25 printed by etching copper layers on the opposite sides of an insulating disc 11, interconnected by rivets 27, and so arranged that their radial portions 19 on the two sides are circumferentially spaced. The alternating field, created by a source 31 supplying one or more electromagnets 33, 35, induces in the rotor winding 17, 25 an alternating tension which results in a pulsating unidirectional current in the closed circuit, and the application of the unidirectional field, created by a source 41 supplying electromagnets 37, 39, to adjacent ribs 17 or 25, sets up a driving torque, the direction and magnitude of which depends upon those of the D.C. voltage selected by a voltage divider 43. Speed control may also be effected by varying the current strength in coil 35 or displacing one or more of the electromagnet cores. The unidirectional field alternatively may be created by one or more permanent magnets, and the invention is also applicable to motors having cylindrical or drumshaped rotors with wire coils. The element 29 may be a germanium diode.

Abstract: 1,171,173. Photo-electric absorption measurement. SAUNDERS - ROE DEVELOPMENTS Ltd. Sept.8, 1967 [Sept. 9, 1966], No. 40494/66. Heading G1A. In a radiation absorption measurement where radiation after passing through a sample and a reference radiation is alternately received by a detecting system, the mean value of the varying output of the system is maintained constant by adjustment of the amplification of the detector system so that the alternating component of the output, which is the difference between the reference radiation and the attenuated radiation, is corrected for inherent drift in the amplification system and for decay in the sources of radiation and is also linearly related to the parameter of the sample causing an exporential attenuation of the radiation. As shown in Fig. 1, # or γ radiation from source 1 after passing through a pipe 3 carrying petroleum irradiates a phosphor 11. A reference source 6 of similar radiation is mounted upon the rotating shaft 5 of a shutter 8, so that a photo-multiplier 13 alternately receives light scintillations from phosphor 11 and light scintillations from another phosphor 12 when irradiated by the rotating reference radiation source 6. The photo-multiplier output is amplified at 14 and 15 and the mean value of the amplified signal appears at the low pan filter 21 to be compared with a reference voltage 22. The difference voltage is amplified at 20 to supply indirectly heated thermistors 18, 19 in a feed-back path of amplifier 15 to thereby maintain the mean value of the output of amplifier 20 at the value of reference source 22. The alternating component of this output appears at capacitor 23 and is rectified synchronously with shutter 8. This output is linearly proportional to the parameter of the petroleum causing an exponential attenuation of the radiation passing there through.
