Patent GB-1056222-A (GB)
Title: A process for obtaining composite high lustre-nickel/chromium coatings, and objects coated by this process
IPC: C23C18/36
Filed: 1964-01-02
Abstract: Protective coatings are formed on metals by depositing first a high lustre nickel coating then an intermediate layer of metal from a bath of pH above 6 containing in suspension a solid non-acid resistant silicate obtained by reaction of lime and/ or magnesia with diatomaceous earth and having in suspension in water an alkaline reaction, and finally chromium.  Typically the bright nickel is electrodeposited from a Watts type bath of pH4 containing also quinaldinium ethiodide, p-toluenesulphonamide and sodium lauryl sulphate at 55 DEG C. and the chromium is electrodeposited from a chromic acid-sulphuric acid bath at 40 DEG C., while the intermediate coating may be electrodeposited or formed by electroless plating and may be of Ni, Co, or Ag.  For such electrodeposited nickel layers, the baths may be of the Watts type and include brighteners such as saccharin and quinaldinium ethiodide, for electrodeposited cobalt the basic bath may be of similar composition and include saccharin, and for electrodeposited silver the bath may be a cyanide bath containing as brightener an equimolecular mixture of selinium diethyl dithiocarbomate and tetraethyl-thiuramdisulphide, while for electroless nickel deposition the bath comprises nickel chloride, sodium hypophosphite and sodium citrate.  The silicates included in the intermediate layer baths comprise in addition to SiO2 considerable amounts of other oxides e.g. a combined CaO + MgO content of 18 to 36%, 3 to 9% Al2O3 and from 12 to 23% total of Na2O, K2O and Fe2O3.  For comparison purposes, the intermediate layer is formed from baths including, instead of the silicates, magnesium hydroxide, calcium hydroxide, alumina, barium sulphate, kaolin, diatomaceous earths, or the silicates used in the invention after washing with acid, e.g. HCl, and the initial bright nickel layer is omitted.

Title: Processed coking coal
IPC: C10B49/08
Filed: 1953-02-05
Abstract: 724,774. Fuel; coking. KRUPPA, W. J., and RINCKHOFF, J. B. Jan. 5, 1953 [Jan. 18, 1952], No. 307/53. Classes 50 and 55 (1). Badly swelling and caking coals, in pulverized form, are treated, prior to coking, by flash heating whilst being maintained in fluidized condition by ordinary air, the heating and consequent oxidation being at a temperature between about 675‹ F. and 800‹ F., the oxidized coal being quickly cooled and separated from the carrier air. As shown, coal pulverized in a mill 2 is picked up by hot air delivered from a furnace 3 by means not shown, the coal, thus dried, being delivered, via a cyclone separator 6, to a tank 15 provided with level indicators L2, L3 and a pressure indicator. The hot coal is fed from the tank 15 through a valve 16<SP>1</SP> to a fluidizing pump 16, fluidizing air being provided by a compressor 17, the pump delivering the coal through a pipe 24 to the heating coil 21 in the oxidizer which is fired by a gas or oil burner 27. Cooling of the coal is immediately effected in the coil 22 by means of a spray 32. A cyclone separator 23 delivers the coal to a briquetting press, or through the line 35 to storage. Samples for periodic checks are withdrawn at 37. Air from the cyclone 6 is recycled to the mill 2 by a fan 8, a part of the recycled air being vented at 13 after being divested of dust in the cyclone separator 11. The briquetted coal is converted into coke by carborizing in a stream of hot tar-denuded gases derived from the distillation of the briquettes.

Title: Improvements relating to the casting of metals
IPC: B22D19/00
Filed: 1930-01-08
Abstract: 337,286. Sugimura, I., Magarisawa, K., and Yasumoto, M. Jan. 8, 1930. Casting processes. -Metal is cast so as to have a sheath of another metal formed on it during the casting process, the method only being applicable when the core metal has a higher melting - point, a s m a l l e r specific gravity and a greater surface tension than the sheath metal, and when the metals do not form an alloy. Under these conditions, if the metals be melted and mixed in a vessel, the sheath metal 2, Fig. 1, is stated to assume the form shown, under capillary attraction. When poured into the mould, the core metal 1<1>, Fig. 2, is covered with the sheath metal. Reducing agents such as aluminium, phosphorus, magnesium and arsenic to prevent oxidation, and fluxes such as ammonium chloride, borax, alum and chalk may be added to the molten mixture. For instance, 1 to 3 parts of phosphorus, 0.2 to 0.5 of arsenic, 3 to 6 of borax, 10 to 60 of aluminium, and 1¢ to 2¢ of chalk may be added to ten thousand parts of the molten metals. Combinations of metals which are suitable for the process are cast iron or iron alloys with copper, copper alloys, lead or tin, and zinc or aluminium with lead.

Abstract: 598,590. Selective signalling. HORVITCH, G. M. Jan. 10, 1945, No. 833. [Class 40 (i)] [Also in Group XL] An indicator for dog racing tracks &c. in which the competitors run in separate lanes, is arranged to show the number of the winning animal &c. and if desired the order of arrival of the others under control of photo-electric apparatus. As shown, the indicator comprises lamps X, one for each dog, and sets of lamps A ... F, one set for each position to be indicated. Each set comprises a lamp for each dog and has a control circuit such as that shown in Fig. 2. When a dog finishes the race, he interrupts a light beam and so causes one of the wires 31 ... 36 to be effectively connected to negative battery by the firing of a discharge tube. Assuming that he is the first dog to finish and that the control circuit, Fig. 2, belongs to the set of lamps A, the relay R1 ... R6 connected to the energized wire operates and locks, lights the lamp 1 corresponding to the winning dog and energizes RX which disconnects the remaining relays R1 ... R6 and prepares the control circuit of the group B. The lamps X are energized in series with the corresponding relays. In the case of a dead heat, two relays operate simultaneously and lock and two lamps in the same set are energized. The detecting arrangement comprises three photo-electric cells 12 coupled in parallel to a (gas-filled) tube 20 which passes on an impulse to a gas-filled tube 15, the anode relay 29 of which connects the wire 31 to the anode to energize relay R1. With switch 24 in the position shown, the circuit involves diode rectifier 37. In the alternative position, the switch 24 adapts the circuit for detecting more rapid objects by eliminating the rectifier. The number of photo-electric cells and light sources can be reduced with the aid of mirrors. A timing device may be stopped by the arrival of the winner.

In front of the buckets the base of the trench may be cut and the soil loosened by a blade of inverted T-shape. The edges are sharpened to form cutters, as are those of blades 13 for cutting the trench-sides. The frame 1 is mounted on skids 4 and the height and tilt may be adjusted by screws 9 and handwheels 10. A land wheel may replace one of the skids, and for transport purposes wheels may be provided on both sides.
