Title: Improvements in or relating to methods of manufacturing semiconductor systems
IPC: H01L29/40
Filed: 1954-12-30
Abstract: 786,281. Semi-conductor devices electrodepositing indium. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 30, 1954 [Dec. 31, 1953], No. 37658/54. Classes 37 and 41. A method of making semi-conductor devices comprises applying electrode material to one end of a connecting conductor, placing said end on a semi-conductor body and then heating the whole assembly to fuse the electrode material to the conductor and to alloy it with the body. The material may be applied to the conductor by cataphoresis, evaporation or atomization, or by electrolysis, e.g. from a solution of In, KCN, KOH, and dextrose in water in the apparatus shown in Fig. 1 in which the conductors 4 are held in a clamp 5. Where an alloy electrode material, e.g. Pb-Sb alloy on a nickel wire, is required, the components thereof are electrolytically deposited separately and fused to form an alloy either before or during the process of alloying with the semi-conductor. It is desirable to use a connecting conductor non-wettable by the electrode material, e.g. tungsten, in which case it may be tipped with a readily wetted metal, e.g. gold or copper, before the electrode material is applied to it, to control flow of the material over the semi-conductor surface. The body and conductor may be held in a special templet and fused by heating the whole assembly, or two such tipped conductors which may be the same or different may be joined to form a single conductor which is bent to circular form so as to clamp the body between its ends.

Patent GB-788924-A (GB)
Title: Automatic electric control systems for grinding mills
IPC: G05D5/06
Filed: 1954-12-31
Abstract: 788,924. Automatic control systems for grinding mills. WESTON, D. Dec. 31; 1954 [April 5, 1954], No. 37822/54. Class 38 (4). The viscosity and magnitude of the charge in a wet grinding mill are maintained at optimum values by regulation of one or both of the feed rates of the solid and liquid charge components in accordance with signals representing the sound level or power input to the mill motor, the latter signals being indicative of the said mill conditions. In an arrangement for a fine grinding mill, Fig. 2, the sound or power signal is compared with separate references in a comparator to regulate both solid and liquid feeds, the solid reference corresponding to a desired charge for maximum output and the liquid reference to an optimum viscosity for the desired degree of comminution. In the case of a secondary mill with a fixed solid feed from a primary mill, a sound signal is compared with a single reference to vary the liquid feed to maintain optimum viscosity. A primary mill may also be operated with a constant solid or liquid feed, the other feed being varied by a sound signal to maintain optimum viscosity. A power signal is not suitable for control of a single feed since it is not indicative of mill operating conditions unless the viscosity is independently maintained constant. In a coarse grinding mill, the pulp density of the charge is proportional to the viscosity, so that a fixed solid-liquid feed ratio may be employed, Fig. 4, the solid feed being regulated by a power or sound signal. The signal for the liquid feeder may be derived from the solids feeder, or from a weightometer associated with it. The solids feed control signal derived from sound level may be monitored in the solids comparator if a critical motor loading is exceeded, and a powerderived solids feed control signal may be monitored by a sound signal if some other operating condition becomes excessive. A dynamic microphone detects the sound or ultra-sonic vibration signals, and the circuit may include a band- or high-pass filter. An electronic watt-meter detects the motor power input, and gives a rectified output proportional to it for comparison with the reference. The comparator supplies a difference signal to the proportion feeder which may be of electromagnetic pulse type in which the feed is regulated by variation of the amplitude of vibration of the feeder plate. The liquid feeder may be a motor-operated valve in the supply line. A circuit suitable for a comparator controlling a saturable reactor in the proportional feeder supply is described in Specification 788,925.

Filed: 1956-12-17
Abstract: 798,409. Centrifugal separators. THERMIX CORPORATION. Dec. 17, 1956, No. 38475/56. Class 23 [Also in Group XIII] In an apparatus for separating mist particles from gases the fine mist particles are agglomerated into larger drops in a chamber 12 before the gas is passed through a number of parallel operating centrifugal separators 30. The gas enters through an inlet 13 into the chamber 12, within a gas-tight housing 10 of preferably welded cylindrical construction, and passes through a pad of coiled knitted wire layers 16, Figs. 3 and 4, backed by a supporting grid 17. Some of the liquid particles are here separated from the gas and flow out of a drain 18 but the greater number of them, agglomerated into larger drops, are torn from the pad by the gas and pass with the gas through an opening 19 in a transverse partition 11 into a chamber 20 housing the centrifugal separators 30. Separated liquid is discharged from the centrifugal separators 30 into a chamber 24 having a drain 25 while the gas passes into a chamber 26 leading to an outlet 15 in the housing 10. The pad 16 may be made up of layers of knitted metal wire of small gauge placed one on another or the knitted wire may be made as a strip of the required width rolled into a tight coil. The centrifugal separators 30 are most efficient at high velocities while at low velocities the agglomerating effect of the pad 16 is greater, forming larger drops which are more easily separated; the actions of the pad and the centrifugal separators therefore complement each other for variation in the gas velocity.

Title: Process for preparing substantially ash-free and low-sulphur fuel and product thereof
IPC: C10G1/06
Filed: 1965-09-09
Abstract: An improved fuel which is ash-free and low in oxygen and sulphur is made from a carbonaceous material (coal, lignite, peat) by the following process:- the finely divided material is mixed with an organic solvent (e.g. an oil obtained from the process) having a B.R. of 150 DEG  to 750 DEG  and the mix heated under hydrogen at a partial pressure of at least 35 atmos. to a temperature in the range 370 DEG  to 500 DEG  C. The mix is held under these conditions while the relative viscosity (defined below) first rises above 10 and then falls below 10, at which point the undissolved residue is filtered or centrifuged off and the solvent is extracted from the solution so obtained to leave the required improved fuel, which in two specific examples, using Kentucky No. 11 coal as raw material, was a brittle material melting respectively at 180 DEG  and 220 DEG  C.  Relative viscosity is defined as the ratio of the viscosity of the mix to that of the original solvent, both measured at 99 DEG  C.  Hydrogen, obtained after scrubbing the gases given off at the filter stage of the process, is recycled under the required pressure to the mix for delivery to a preheater and dissolver, see Figure (not shown). Specific solvents are middle oil from coal (B.R. 190 DEG  to 300 DEG C.), anthracene oil and creosote oil, and preferred solvent/coal ratios range from 0.6:1 to 4:1.
