Patent GB-2471699-A (GB)
Title: Electrical generation by multiple turbines
Inventor: POLLOCK CHARLES
IPC: F03B17/06
Filed: 2009-07-09
Abstract: A wind or water powered turbine system uses two or more turbines which each have a diameter smaller than a single turbine sweeping the same equivalent area. The rotational speed of each turbine of the turbine system is therefore higher than a single turbine of equivalent power, so the total volume of electrical generators will be smaller, assuming they are directly driven. Each of the turbines can be mounted within a duct and the ducts can be arranged around a central point. The turbines may be arranged around a single generator, and may be coupled to the generator shaft via a belt or chain drive 103. Two or more turbines may be electrically or mechanically connected in series at low speeds and in parallel at high speeds.

Title: Process for the neutralization of sulphonic acids
IPC: C07C303/44
Filed: 1952-04-21
Abstract: Alkyl aryl sulphonic acids are rendered substantially neutral by a process comprising contacting a finely divided stream of the acid with a finely divided stream of an aqueous solution of alkali metal carbonate in substantially equivalent proportions, the contacting being effected in the upper part of a tower into which the two streams are passed through separate nozzles provided closely together.  The two nozzles may be arranged side by side at the top of the tower with their outlets directed towards each other or the nozzles may be arranged concentrically.  Gases comprising liberated carbon dioxide, air used to atomize the reactants and entrained sulphonates or sulphonic acids, issue from the tower top and are washed in a scrubber by a circulating water stream a portion of which, containing the sulphonates or sulphonic acids is intermittently or continuously withdrawn and added to the neutralized sulphonate solution collecting at the bottom of the neutralizer-tower, fresh make-up water being added to the washing system.  The neutralized solution may be withdrawn to a second vessel where its pH may be adjusted to desired value by means of alkali metal hydroxide or carbonate or sulphonic or sulphuric acid.  An example describes the neutralization of a C10-mono alkyl benzene sulphonic acid with aqueous sodium carbonate.

Abstract: 364,453. Fluid - pressure brakes. KNORR-BREMSE AKT.-GES., 9, Neue Bahnhofstrasse, Lichtenberg, Berlin. April 2, 1931, No. 10113. Convention date, Feb. 28. [Class 103 (i).] In control valves for r fl u i d pressure brakes of the kind .comprising a valve operating piston subject to the brake cylinder pressure and operated through a spring by the control lever, so that each position of the control lever gives a definite braking pressure, the valve is of piston form and it and the control piston are provided with bellows-like sleeves to prevent leakage past the sliding surfaces. The device comprises chambers b, c communicating respectively with the compressed air reservoir and the brake cylinder. A valve body d slidable in the casing a against a spring f has an annular part h forming the inlet valve and a part k, m forming the outlet valve co-operating with an aperture l in a sleeve or piston m which slides in the fixed parts n, o. A spring q engages a ring p projecting from the sleeve m to urge it downwardly. A spring r is disposed between the sleeve and a piece s engaged by the operating lever u. A passage i connects the chamber c to the upper side of the valve body d. 'With the parts in the normal position shown, the brake cylinder is exhausted through the passages l, y. When the lever u is moved to the right, the sleeve m is moved by the spring r to seat the outlet valve k and open the inlet valve h and compressed air flows to the brake cylinder until the pressure therein acting upon the upper surface of the sleeve m is sufficient to overcome the spring r when the valve h recloses. The brake cylinder pressure is dependent upon the degree of compression of the spring r when the valve h closes and thus upon the extent of movement of the lever u. Corrugated spring or bellows-like sleeves v, x prevent leakage of air from the chamber b to the chamber c and from this chamber to the atmosphere respectively, past the sliding cylindrical surfaces of the valve d and piston m.

Title: Process of recovery of oil contained in agglomerated substances obtained by the churning of pulverised substances in a bath of water mixed with oil
IPC: C10G1/00
Filed: 1923-04-14
Abstract: Oil is recovered by heat and very high pressure instead of by distillation from the butter-like mass produced when coal is purified by the Trent or similar flocculating process.  In an example coal passing a sieve of 200 meshes per sq. cm. is agitated with water and petroleum fuel oil.  The separated "butter" is compressed at 100 DEG C. in filter processes used for making lignite blocks or bricks. Under a pressure of 1 ton per sq. cm. 78 per cent of the oil is recovered, under 1.7 tons 91 per cent.  When only a portion of the oil is pressed out the residue acts as a binder, and the coal and lignite blocks may be used directly without the addition of tar and the like.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the hot or cold pressing of "butters" produced from coal, lignite, or ores.  This subject-matter does not appear in the Specification as accepted.

Abstract: 812,652. Pipe joints. BRITISH THOMSONHOUSTON CO. Ltd. Dec. 12, 1957 [March 28, 1957], No. 10198/57. Class 99(1). In a duct compensator wherein a flexible element provides a fluid-tight connection between two parts 2, 3 of the duct, there is means connected with the parts and providing therebetween a non-rigid connection preventing relative movement of the parts in the direction of the duct axis under fluid presssure forces, and hinge means connected with and constraining the parts against relative movement in a direction transverse to the axis whilst being relieved of forces in the direction of the axis. As shown, the axially-aligned duct parts 2, 3 are connected by a metal bellows 1, and tie-bars or plates 4, 5 extend between lugs 6 secured to the parts, the tie-bars being of reduced crosssection at the middle thereof. Annular plates 8, 9 have secured thereto pairs of hinge plates 10, 11 and 12, 13 disposed in planes perpendicular to the hinging axis of the compensator, the plates 10, 11 being bifurcated to receive the plates 12, 13 and provided with openings coaxial with the hinge axis for hinge pins 14, and the plates 12, 13 having apertures 15 to accommodate blocks 16 through which the pins 14 pass; the upper and lower surfaces of the blocks slidingly fit the corresponding surfaces 17, 18 of the apertures 15 and have a length less than that of the apertures whereby a lostmotion connection is provided. The blocks prevent relative movement in the vertical direction of the hinge plates so that the latter are constrained for relative movement about the pins 14. To relieve the pins of forces resulting from any tendency to relative angular movement of the parts 2, 3 about the longitudinal axis of the duct and to resist lateral movement of the parts relatively to one another along the hinge axis, plates 19, 20 attached to the ring 8 have parallel-sided teeth 23 slidingly received in corresponding recesses 24 in plates 21, 22 secured to the ring 9, axial clearance being provided between the teeth and recesses. In a modification, the tie-bars are arranged internally of the bellows and parts 2, 3 and, for example, a single plate is disposed on the diametral plane of the duct and the parallel edges thereof are secured to the parts 2, 3; alternatively, a single tie-bar is located on the longitudinal axis of the duct and is connected to spider members in the parts 2, 3.

Patent GB-996738-A (GB)
Title: Improvements in the purification of coal gas
IPC: C10K3/00
Filed: 1964-03-11
Abstract: Coal gas is purified by passing it with a gasifying agent, e.g air or steam, at 700 DEG  to 1300 DEG  C. over a cracking catalyst, e.g. a metal oxide and/or sulphide of an element of Group 6, 7 or 8 of the Periodic Table.  The preferred temperature is 900 DEG  C., and, where steam is the gasifying agent, the crude gas may contain enough steam, namely 0.3 to 0.8 kg./Nm3, for the cracking step.  The process transforms most of the impurities (ammonia, tar, organic sulphur compounds, various hydrocarbons) into gases which need not be removed, but acidic impurities (H2S, HCl) must be removed before or after cracking by any known method and residual water is removed from the cracked gas. Two examples are described for purifying coke oven gas, one employing a nickel-tungsten-sulphide catalyst, and the other, after pretreatment at 300 DEG  C. with a zinc oxide catalyst, a nickel and aluminium oxide catalyst for the cracking.

Abstract: 1347163 Rotary I C engines AUDI NSU AUTO UNION AG and WANKEL GmbH 21 April 1971 [21 April 1970] 10405/71 Heading F1F In a supercharged rotary I.C. engine, a fourapex engine piston 11 and a two-apex compressor piston are mounted on a pair of 180 degrees out of phase eccentrics 5, 6, on a common shaft, the piston 11 working in a three-lobed epitrochoidal housing 7 separated from a one-lobed epitrochoidal compressor housing 8 by a wall 3 having a passage 14 for transferring air from the compressor to the engine, the engine casing 7 having a passageway 17 inter-connecting a pair of lobes. A small angular displacement i. e.  10 degrees to 30 degrees between the two housings brings the compressor outlet and engine inlet into axial alignment and thus reduces the dead space of passage 14. The wall 3 carries a main bearing 9 of sufficient magnitude to allow the compressor piston to be mounted in cantilever and provide the sole counter-balance for the engine piston at that end of the shaft. The passageway 17 connects that chamber approaching the end of the expansion stroke 23 with the next chamber ahead 24 to provide further expansion, when the pressures in the two chambers 23, 24 are of the same order of magnitude. A fresh air port 19 is provided in one or both side walls 1, 3 of the engine to ensure complete combustion of the gases passing through the passageway 17. The volume of passageway 17 may be made pressure-dependent by means of a movable plunger (26) Fig.6 (not shown) mounted in a radial opening communicating with passageway 17.
