Title: Process for extracting chromium ore
IPC: C22B34/32
Filed: 1926-08-30
Abstract: 270,143. Zahn & Co. Bau Chemischer Fabriken Ges., and Wickop, L. Aug. 30, 1926. Alkali chromates.-The residue obtained when chromium ores are heated with an insufficient quantity of alkali carbonate to extract all the chromium and the reaction product is lixiviated, is mixed with a proportionately small quantity, say 2-3 parts, of burnt lime or an equivalent quantity of alkaline earth carbonate to each part of iron oxide in the residue, and roasted with the requisite quantity of alkali carbonate to extract the remaining chromium, preferably in a rotating furnace. By this means complete extraction of the chromium is possible. Alternatively the residue may be admixed with untreated ore and an insufficient quantity of alkali carbonate for complete extraction and be reheated and lixiviated, the residue then obtained being treated as above; or the ore in the residue, after separation from iron oxide and gangue by floatation, wind sifting, &c., may be reheated with an insufficient quantity of alkali carbonate for complete extraction, and the residue obtained by lixiviating the reaction product be treated as above. Examples of the different modes of treatment are given.

A steering system for a ship having a transverse duct traversing a hull adjacent one end thereof and below the water line, Figs. 1 to 5 (not shown), comprises a blade wheel propeller having blades which project into said duct and means for driving the propeller, the section of each blade being symmetrical relative to a central plane at right-angles to the chord of the blade and the blades being arranged to perform a controlled rocking motion about a neutral position tangential to the circular orbit (Figs. 4 and 5) of the blades, the propeller also having control means (8) which is either fixed in a position displaced from the central neutral position or is displaceable from this central neutral position along one diameter only. As illustrated in the Figs. (not shown), the ship is driven by a propeller (2). A transverse duct (4) is arranged in the bow and (Figs. 4 and 5) illustrate how the jet of water employed to steer the ship may be directed to either port or starboard by reversing the direction of rotation of the propeller. The control disc (8) lies in front of the centre of the blade circle in the direction of travel of the boat. Figs. 6 and 7 (not shown) illustrate a displaceable control disc (10).

Title: Rate of climb meter
Inventor: FOWLER MAURICE E
IPC: G01P3/62
Filed: 1954-07-23
Abstract: 753,951. Rate of climb meters. COLLINS RADIO CO. July 23, 1954, No. 21581/54. Class 106 (2). In a rate-of-climb meter operated by a pressure differential acting on a diaphragmcapsule, the time lag in registering changes in the rate of climb is overcome by the influence of a mass mounted to respond to acceleration or deceleration. The capsule 17 is mounted on a block 14 attached to a shaft 31 secured by a spring portion 28 to the instrument casing 10. A flexible tube 11 communicating with atmosphere and having the usual restricted opening 13 into the casing, is connected via a bore 15 in the block 14, to the interior of the capsule. A shaft 18 and gearing (not shown) link the capsule to the indicator pointer 26. The shaft 31 carries a mass 33 attached by springs 34, 35 to the casing, and is connected by a link 43 with a damping piston 42. Movement of the mass 33 due to changes in the rate of climb, raises or lowers the block 14 and modifies the indicator reading through the capsule and its connection with the pointer 26.

A loose ball valve i retained in a recess by an arm secured in position by a screw is adapted to fall away from its seat and admit atmospheric air when the vacuum in the conduit falls below a predetermined minimum.
Patent GB-455453-A (GB)
Title: Process for the production of valuable hydrocarbons rich in hydrogen
IPC: C10G45/44
Filed: 1935-08-01
Abstract: In the production of hydrocarbon products rich in hydrogen from middle oils or high boiling hydrocarbon mixtures by treatment with hydrogenating gases at elevated temperatures in presence of hydrogenating catalysts comprising sulphides, an increased yield of products rich in hydrogen which have a boiling point range within the limits of that of the initial materials is obtained by adding a small amount of a gaseous or liquid substance having a basic reaction, e.g. pyridine bases, ammonia, trimethylamine, aniline.  A small amount of an alkaline compound, e.g. potassium or lithium carbonate may also be added.  Sulphides specified are those of the metals of Groups 6--8 particularly sulphides of molybdenum, tungsten, chromium uranium or rhenium.  A middle oil is heated with hydrogen under 200 atms. pressure to 450 DEG  C. in a gas-heated preheater.  Ammonia is added until its partial pressure is 5 atms. and the mixture is passed over lumps of tungsten disulphide in a reaction vessel.  A product containing 80 per cent of middle oils rich in hydrogen is obtained. Reference has been directed by the Comptroller to Specification 247,586, (as open to inspection under Sect. 91 of the Acts), [Class 32].

Title: Applying organic glaze to porous surface
IPC: C08K3/00
Filed: 1963-05-31
Abstract: A method of providing a surface of a porous body with an organic glaze of a clear coating of a polyurethane resin composition which comprises applying to the surface a base coating of an aqueous synthetic latex which is adapted to dry by evaporation of water to provide an adherent surface layer which fills and bridges the pores and at least partially evaporating the water from the base coating before coating the base coating with a finishing coating of the resin composition.  A suitable latex is a copolymer of a monovinylidene aromatic compound (styrene or a substituted styrene), an acrylate or methacrylate, acrylic or methacrylic acid, and acrylonitrile or methacrylonitrile; synthetic polydiene rubbers, styrene-butadiene polymers, butadiene-acrylonitrile polymers, vinylidene chloride-acrylonitrile polymers, polymers of styrene, polyvinyl acetate, or acrylates, co-polymers of vinyl acetate and other vinyl monomers, or co-polymers of vinyl and vinylidene chlorides. The latex may contain fibrous material such as asbestos, fibre-glass, or wood fibres, and pigments (e.g. titanium dioxide) and fillers (e.g. ground marble); it may be applied by brush, roller, trowel or spray.  The polyurethane is preferably the product of a hydroxyl-containing polyester and an isocyanate and may be applied by brushing or spraying.  Several coats of each composition may be applied.  The porous body may be concrete or cinder block.

Abstract: 480,424. Valve circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 9, 1937, No. 21906. Convention date, March 10. [Class 40 (v)] A four-terminal phase or polarity reversing network comprises a potential divider of two resistive, or reactive impedances of the same phase angle and nearly equal values, R1, R2, Fig 4, connected between input and output terminals 1, 3, the point ug which is preferably adjustable being connected to the grid of the amplifier valve V whose anode is coupled to output terminal 3 The cathode of the valve is connected to input and output terminals 2 and 4 which are common, and if instead of the blocking condenser C, a source of voltage to oppose the anode supply BA is employed to couple the anode to terminal 3, the network is capable of reversing D.C. polarities. The push-pull voltages obtained between terminals 3, 5 may be used to feed a push-pull amplifier stage or feed a balanced two-wire line from a concentric cable, particularly at television frequencies where transformers are unsatisfactory. The grid-anode capacity of the valve V may be compensated for by connecting an equal capacity across the element R1. In an embodiment, Fig. 7 (not shown), the amplifier valve V and the valve supplying the input terminals are combined as one double triode valve. Fig. 8 shows the device employed to obtain sum and difference voltages for application to a push-pull modulator. The modulation Vo is applied between terminal 2 and a datum 8 such as earth, the carrier u being applied between terminals 1 and 2. Voltages Vo + u, Vo - u are obtained between terminals 5 and 3 and the datum 9, and applied to the modulation circuit consisting of resistances W1, W2 and rectifiers G1, G2.
