Title: Improvements in or relating to methods of and means for introducing inflation bags into tyres to be vulcanised
IPC: B29D30/06
Filed: 1966-06-22
Abstract: 1,119,717. Moulding tyres. K. ZANGL [trading as KARL ZANGL]. 22 June, 1966 [5 Oct., 1965; 29 March, 1966], No. 27803/66. Heading B5A. In a tyre vulcanizing press for either retreading or for treating new tyres, including axially movable tyre shaping parts 2, 3 and a relatively movable cylinder 9 accommodating an inflation bag 11, means are provided for introducing a part of the bag into the tyre after the beaded edges of the tyre have been brought together by their engagement with bead rings 6 and 7. The latter are secured, respectively, to a resiliently supported body 8 and the lower edge of the cylinder 9. The beaded ends of the bag are attached, respectively, to the lower end of the cylinder and to a fitting 19 on the lower end of a piston rod 12 of a cylinder 12a. After locating a tyre on the shaping part 3 with its bead in contact with the ring 6, the cylinder is lowered to bring the rings 6 and 7 together whereby the tyre beads are brought to the position of Fig. 1. Pressure is then applied to the bag via a duct 20, and the body 8 is forced downwardly by the bag pressure causing the rings 6 and 7 to open and allow part of the bag to be forced into the tyre; the cylinder 9 is moved upwardly and the tyre and bag reach the position of Fig. 2, at which position the shaping parts 2 and 3 are brought together. The opening of the rings 6 and 7 to receive the bag may be assisted by an independent upward movement of the cylinder 9. A heated pressure medium such as hot water or steam may be supplied to the bag. Downward movement of the fitting 19 during bag insertion is controlled by an extension 18 which passes through the body 8 and engages an adjustable stop 31 supported on the lower ends of rods 22 forming guides for the body 8.

Title: Improvements relating to air inlets in self-propelled vehicles
IPC: B60K11/02
Filed: 1953-10-14
Abstract: 770,647. Motor vehicles. JENSEN MOTORS, Ltd. Oct. 14, 1954 [Oct. 14, 1953], No. 28243/53. Class 79(3). [Also in Group XIII] In an engine-driven vehicle having a housing 13 for the engine (not shown) and radiator 11 with a forwardly facing aperture of greater width than height a closure member 28 for the aperture is pivotally mounted about a horizontal axis. As shown the housing 13 has an apertured front cowling 17, the aperture having an ornamental bezel ring 37 and inwardly turned flanges 29 and its height and width being in the ratio of about 1 to 3. Pivoted to the flanges by stubs 30 is the closure member 28 having an approximately C or D section. Pivotal movement of the member 28 is controlled through a Bowden cable 40 from the driver's station, a spring 45 urging the member open against a stop 35 and the cable 40 being associated with positive or other abutment means to restrain such opening. The member 28 is so shaped that until it has turned through 45 degrees from the closed position the lower portion of the aperture in the cowling 17 is not open. In a modification, Fig. 5 (not shown), pivotal movement of the closure member is controlled thermostatically. In a further modification the pivotal axis of the closure member is arranged below the centre of air pressure of the member and spring urged into its closed position whereby the member is opened by movement of the vehicle. Alternatively the pivotal movement can be controlled by the difference of air pressure on the forward and reverse sides of the closure member, the difference being caused by rotation of the enginedriven radiator fan. Further the thermostatic or air pressure control may be subject to an overriding manually operable control means. The air passing through the aperture may pass to the engine either through or around the radiator and be exhausted from the housing through lateral openings and an opening at the upper rear end thereof, the latter opening counteracting the formation of frost or ice on the windscreen. The radiator may be provided with a blind or the like. The invention may be applicable to a vehicle having gas turbine engine, the closure member further serving the function of preventing the ingress of foreign bodies and undesirable weather conditions to the gas turbine air intake, and in controlling inlet air for turbine speed regulation. According to the Provisional Specification ducts or air directing members may be provided behind the closure member to deliver air to the radiator, engine and front brakes.

Title: Reduction of corrosion in the distillation of hydrocarbon oils
IPC: C10L1/228
Filed: 1952-11-10
Abstract: In the distillation of hydrocarbon oils, particularly Middle East crudes, and particularly when an aqueous phase is present in the condensers, corrosion of the distillation apparatus is inhibited by the introduction into the apparatus of guanidine or a guanidine derivative such as diphenyl guanidine, guanidine chlorohydrate or diphenyl guanidine hydrochloride.  The amount is preferably between 0.001 and 1 per cent. by weight of the water present.  In an example, a crude oil was distilled in an apparatus consisting of a coil heated by a metal bath, a flash tower from which reduced crude was tapped, and a distilling tower with oil condensers at the top, gas oil being tapped at the bottom.  At the inlet of the condensers was placed a polished metal tube cooled by water circulating inside.  Between the head of the column and the p  condensers means were provided for introducing a fog of water or water containing inhibitor (diphenyl-guanidine hydrochloride). The working conditions were: Furnace temperature 300 DEG  C., head of column temperature 145 DEG C., head of column pressure 300 g./sq. cm., percentage water in condensed oil 8-9.  The pH of the water was adjusted to between 6 and 8 by injecting ammonia and sodium carbonate into the crude material. Figures are given for the loss in weight of the polished tube at various pH values (a) with no inhibitor; (b) with 0.01 per cent. of inhibitor by weight of water decanted.  Other examples are given of the loss in weight of steel plates immersed in emulsions of oil fractions from Middle East crudes in water containing sodium chloride and hydrogen sulphide at various pH values with and without inhibitor (diphenylguanidine hydrochloride).  Reference is also made in the specification to the injection of ammonia or sodium hydroxide or carbonate into the head of the distillation column or just before the condensers to neutralize the aqueous phase.

Title: Testing of gases for paramagnetic components
IPC: G01N27/74
Filed: 1971-06-17
Abstract: 1350561 Analyzing gases magnetically SIEMENS A G 17 June 1971 [18 June 1970] 28571/71 Heading G1N An apparatus for testing a gas for paramagnetic components e. g. oxygen content of a gas mixture is arranged so that the effects of unwanted movement of the apparatus on the readings therefrom are mitigated. In the arrangement of Fig. 1 a test chamber C, Fig.4 (not shown) is arranged between poles P1, P2 which produce an alternating magnetic field overlapping part of the chamber C and duct S1. Comparison gas V applied to chamber C via ducts R1, R2, S1, S2 mixes in the region of homogeneous magnetic field between pole pieces P1, P2 with the test gas M applied via duct L2. If the two gases differ in their content of paramagnetic gas the resulting alternating pressure difference occurring between ducts S1, S2 is measured by flow sensitive sensor F in flow paths T1, T2. In accordance with the invention flow paths T1, T2 are arranged in a figure of eight manner and the plane of the ducts positioned at an angle Ï less than 90 degrees to the axis of the chamber C. Thus in the event of rotation of the apparatus or other movement there are produced in the portions of each flowpath T1, T2 opposed inertial forces on the gas which cancel out. By arranging sensor F on a plane of symmetry variations in the density of the gas in ducts T1, T2 caused by pressure fluctuations in chamber C do not affect sensor F. The flowpaths T1, T2 may be formed with a substantially circular or U-shaped portion the mid portion of which is bent back on itself, Figs.3 4 (not shown). The chamber C is flat to provide laminar flow Fig.2 (not shown) and due to the arrangement of chamber and pole pieces P1, P2 the device is independant of small changes in velocity flow.

Title: Method and apparatus for the production of metals, particularly iron (sponge iron) without melting
IPC: C21B13/08
Filed: 1952-11-12
Abstract: 734,698. Obtaining spongy metals. WEBER, L. Nov. 12, 1952 [Nov. 15, 1951], No. 28579/52. Classes 72 and 82 (1). An oxidic ore, e.g. iron ore, is reduced to the metal without melting by contacting the ore with a reducing agent and a heated, granular heat carrier, all the heat necessary to effect reduction of the ore by the reducing agent being supplied by the heat carrier. The ore should be in lump or fine-grained form. If the latter, it may be briquetted with the solid reducing agent. Solid or liquid reducing- agents flow with the ore, gaseous or vaporous reducing agents are used in countercurrent with the ore. Purifying agents, e.g. lime may be incorporated in the charge in lump form or in fine form in the briquettes. A pressure of 5-40 atmospheres, preferably 20 atmospheres, is used. The heat carrier may be inert in the circumstances of use, or may have a catalytic action on the reducing reactions, e.g. iron or heavy metal oxides which promote the formation of water gas. Corundum, quartz, sand, fine ores (including the reduced ore used in the process) or natural or artificial ceramics may also be used as the heat-carrier. The carrier is heated at 1100-1300‹ C., preferably 1150- 1250‹ C. The spongy metal produced may be cooled by the cold reducing gases. The hot gases leaving the process may preheat the charge or be used for carbonization of the reducing agent. Bituminous fuels, fuels having a low tar content, or low and high temperature cokes from peat, brown coal, lignites, pit coal, &c., can be used. Fine-grained fuels can be bound by clay, bitumen, &c. Waste hydrocarbons &c. can be used as liquid agents. Water gas, producer gas, natural gas, and cracking gas can be used, as well as the product of destructive hydrogenation of carbonaceous material. The heat carrier may be recovered by any method including mechanical treatment, flotation and the like. A furnace 1 is charged at 2, the charge leaving at 3 and being separated at 4. The heat carrier is heated at 5, fed in at 6 and screened out at 7 and recirculated. The charge is cooled by circulating cold gas in at 8, or water vapour at 9. Water is condensed at 11. A rotary furnace may be used for the process.

Title: Improvements in sources of light comprising an electric discharge and luminescent material excited by the discharge
IPC: C09K11/68
Filed: 1937-10-20
Abstract: 504,354. Luminescent materials. GENERAL ELECTRIC CO., Ltd., and McKEAG, A. H. Oct. 20, 1937, No. 28624. [Class 39 (i)] An electrical gas-discharge device incorporates luminescent magnesium - cadmium tungstate excited by the discharge. Discoloration and loss of efficiency of the tungstate can be prevented by mixing the tungstate with free magnesium, oxide or free cadmium oxide or both. In one method of preparing the luminescent material, a mixture of 1 mol. CdO and 2 mols. WO3 is heated to 1000‹ C. for one hour in an oxidizing atmosphere and is then ground and mixed with 1À1 mol. MgO and heated to 1150‹ C. for 1 hour or longer until coloration is absent. The product is then ground with 0À1 mol. MgO and is not subsequently heated to any temperature approaching 1000‹ C. so that the added MgO remains free. In another method of preparing the luminescent material 0À1 mol. of CdO in the form of a solution of Cd(NO3)2 or CdSO4 is added to MgWO4 prepared by the method described in Specification 469,732 from a mixture of 1 mol. MgO and 1 mol. WO3. The mixture is dried at 200‹ C., reground and heated in air at 1150‹ C. for 1 hour. A small amount of lead may be added as described in Specification 469,732. The magnesiumcadmium tungstate is preferably within the envelope in the case of a low-pressure mercury discharge. The electrodes may be cold or thermionic. In the case of a high-pressure mercury discharge, the tungstate is outside the envelope and much cooler than the envelope which is of quartz or other material whose transparency to ultra-violet light resembles quartz. The tungstate may be associated with zinc-beryllium silicate or the chloro-phosphate described in Specification 495,706, [Group XX], which provide red light in which the mercury spectrum is deficient. The discharge may be through neon or a mixture of neon with a small amount of heavier rare gases ; the magnesiumcadmium tungstate may then be used instead of the calcium tungstate mentioned in Specifications 457,486 and 476,240 and must then be within the envelope. Specification 495,415, [Group XX], also is referred to.
