Title: Improvements in the thermal treatment with hydrogen of carbonaceous materials
IPC: C10G45/00
Filed: 1932-01-04
Abstract: <PICT:0385433/III/1> In preheating, prior to destructive hydrogenation, carbonaceous materials, 90 per cent of which boil under 325 DEG  C. and which contain polymerizable constituents, the materials are heated to such temperatures that these constituents polymerize but the bulk of the materials, e.g. at least 50 per cent, remains liquid, the polymerized bodies being carried away by the liquid and thus prevented from choking the tubes.  The polymerized bodies are removed in separators provided at intervals in the preheating tubes where the liquid constituents are distilled off by treatment with preheated hydrogen and are then destructively hydrogenated in the vapour phase, e.g. as described in Specification 379,335.  The separators may be provided with plates or filled with fuller's earth, bauxite and polymerizable materials may be further removed by treatment with sulphuric acid or adsorbents in plate columns or washers.  The residues containing the polymerizable constituents may also be destructively hydrogenated in the liquid phase in admixture with hydrocarbons boiling above 325 DEG  C. and in the presence of catalysts, e.g. oxides, sulphides or phosphates of the metals of groups 3-8.  A heavy benzine boiling at 150-225 DEG  C. is preheated to 270 DEG  C. in a jacketed coil B by the gases and vapours issuing from the reaction vessels K, L, M and is then passed into a separator D from which hydrogen preheated to 480 DEG  C. in a regenerator E is passed through a pipe F, and the vapours and gases evolved are heated to 490 DEG  C. in a preheater H and then destructively hydrogenated in the reaction vessels K, L, M.  The gases and vapours leaving the reaction vessels are divided into portions that pass through the heat exchanger B, the regenerator E and the line O to condensers Q1, Q2, Q3.

Filed: 1961-01-05
Abstract: 933,688. Inverters; automatic voltage and current control. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Dec. 22, 1961 [Jan. 5, 1961], No. 552/61. Classes 38 (2) and 38 (4). In an inverter of the kind in which direct current is switched on alternate half cycles to alternate halves of a centre-tapped transformer, the output is varied by effectively varying the transformer ratio. The inverter basically consists of silicon controlled rectifiers TR1, TR2 which are pulsed alternately by a pulse generator Dr to connect the D.C. supply between the centre-tap and one or other end of the primary of transformer Tf. The commutating capacitor C1 enables one rectifier to cease conduction as the other starts. Two further silicon controlled rectifiers TR3, TR4 enable the D.C. supply to be connected to intermediate tappings on the primary of transformer Tf. During any halfcycle of the A.C. output, the main rectifier, e.g. TR1, is first rendered conducting by a pulse from generator Dr, and then, if the output is not sufficient, the generator Dr supplies a pulse to the further rectifier, e.g. TR3, to render it conducting. Current transfers to this rectifier and the main rectifier, e.g. TR1, ceases to conduct. The point in each half-cycle at which the further rectifiers conduct is said to be controlled either manually, or automatically in accordance with output voltage or current. The silicon controlled rectifiers may be replaced by transistors. Greater numbers of transformer tappings may be provided. The possibility of polyphase arrangements is mentioned.

Filed: 1927-01-10
Abstract: 264,182. Graissage Alcyl, Soc. Anon., (Assignees of Koehler, M.) Jan. 11, 1926, [Convention date]. Capillary-action lubricating.-In a lubricating system as described in Specification 259,567. wherein lubricant is supplied from a tank to a number of distant parts by branched capillary elements, the feed through each element is regulated by exercising pressure on the element so as to vary the cross-section of the capillary ducts therein. This is effected by compressing elements of definite size in calibrated orifices of given diameters. Alternatively, the feed through a capillary element b<1>, Fig. 1, arranged in a bore in a member a<1> is regulated by an adjustable screw d<1> having a tapered end c'. The member a<1> is screwed into a member e<1>, through a conduit f in which the element b<1> passes. Between the member e<1> and a. tread on the member a<1> is held a flat metallic member g<1> having one or more tubular extensions k<1>, each of which is secured on the end of a tube l' containing a capillary element h<1>, which latter is wound round the member a<1> and is connected to the element b<1>, which passes through a hole q<1> in the member a<1>. The sleeve k' is secured to the tube l<1> by driving a small tapered tube m<1>, which may be threaded into the end of the tube, thereby expanding it against the cylindrical or tapered internal surface of the sleeve. The tube l<1> may be made of braided cotton and varnished, or varnish may be applied directly to the capillary element to form an adherent protective coating. The Specification as open to inspection under Sect. 91 (3) (a) states also that such a tube m<1> may be used for securing a tube l<1> in a member k<1> as shown in Fig. 6 (Cancelled), a pointed rod or needle p<2> being provided to determine the flow. Alternatively, the feed may be regulated by an adjustable collar surrounding the capillary tube. The tank may be arranged below the capillary elements and at or below the level of the points to be lubricated, so that flow of lubricant from the elements occurs only when an external force, such as the friction of the parts to be lubricated, is applied thereto. This subject-matter does not appear in the Specification as accepted.

Patent GB-594713-A (GB)
Title: Improvements in and relating to feed assisting means for belt feeding mechanism
IPC: F41A9/51
Filed: 1945-01-09
Abstract: 594,713. Cartridge feed mechanism. WATSON, C. D., and MANSELL, R. C. S. Jan. 9, 1945, No. 760. [Class 92 (ii)] Feed assisting means for the belt feed mechanism of a gun comprises a continuously running motor, sprockets over which the belt passes and clutch elements between the motor and sprockets adapted to be brought into engagement by the rocking of pivoted arms in contact with the belt, these arms being independent of the sprockets and being mounted to rock about their pivots when the tension of the belt exceeds a predetermined value. On a decrease in the tension, the clutch elements separate and the belt is fed to the gun by mechanism within the gun independently of the motor. In the construction shown, a shaft 8 carrying a clutch member 7A is' continuously driven by an electric motor in a casing 1, and a second shaft 9 carrying a clutch member 7B is geared, through reduction gearing to a shaft carrying sprockets 6A over which the ammunition belt passes. Member 7A has a conical face forming one race of a ball bearing 12 whose other race is formed by a ring 14 in the clutch housing 3. Member 7B also has a conical face forming one race of a ball bearing 11 whose other race is formed by a non-rotatable annular ring 16 which can be depressed against the action of springs 18. The two members 7A, 7B are normally kept apart by a spring-pressed ball 10B, the spring of which bears on a floating phosphor bronze disc on member 7A. On a shaft 19 are two arms 20 whose outer ends bear against the underside of the belt and whose upward movements are limited by pins 26 which engage in slots in the sprockets. Each arm carries a rod 22 which bears on the ring 16. When the feeding mechanism associated with the gun is set in operation, the motor is also started, and if the tension on belt remains below a predetermined value the feeding mechanism alone suffices to feed the belt over the sprockets, from which the belt is gradually lifted by a leaf spring 23. When, however, the tension increases beyond that value, the belt depresses arms 20 causing rods 22 to depress the ring 16, the ring in turn serving to cause clutch member 7B to engage member 7A. The motor then assists in the feeding of the belt and when the tension is again reduced below the given value, the springs 17, by lifting ring 16, will disengage the clutch and restore the arms 20 to the position shown.
