Title: Improvements in catalysed exothermic reactions
IPC: B01J8/02
Filed: 1964-02-11
Abstract: A process of gas reaction (e.g. purification of ammonia synthesis feed gas), involving a feed gas mixture containing a component exothermically reactive with oxygen and requiring a minimum temperature before two or more of its components react exothermically with each other, includes burning a proportion of a component exothermically with oxygen so that heat exchange of reacted gas with feed gas raises the temperature of the latter to the minimum required for said reaction.  The burning of a component with oxygen and the exothermic reaction between components may be carried out at the same time, the oxygen being mixed with the feed gas mixture, preferably before heat exchange with reacted gas mixture.  The temperature of the reacted gases is preferably 50-100 DEG  F. above that of the feed gas mixture.  In the case of the purification of an ammonia synthesis feed gas containing H2, N2, CO2 and CO (0.1-0.3 mol per cent), the H2 is burnt with O2 to form water, in the presence of a catalyst, and heat exchange between the reacted and feed gases raises the temperature of the latter to the minimum required for the reaction of H2 with CO and/or CO2 at a pressure of 100-400 p.s.i. and 300-600 DEG F. to form methane and water, thereby removing CO and CO2 impurities from the gas mixture.ALSO:A process involving a feed gas mixture containing a component exothermally reactive with oxygen and requiring a minimum temperature before 2 or more of its components react exothermally with each other, includes burning a proportion of a component exothermally with oxygen so that heat exchange of reacted gas with feed gas raises the temperature of the latter to the minimum required for said reaction.  The burning of a component with oxygen and the exothermal reaction between components may be carried out at the same time, the oxygen being mixed with the feed gas mixture preferably before heat exchange with reacted gas mixture.  The temperature of the reacted gases is preferably 50 DEG -100 DEG F. above that of the feed gas mixture.  The example relates to an ammonia gas synthesis process.

Abstract: 349,930. Dynamo-electric machines. DRYSDALE, C. V., Admiralty, Whitehall, London. Feb. 25, 1930, No. 6195. [Class 35.] Brush-holders; motors, controlling; rotary transformers.-The armature of a separately-excited motor 2 is supplied from a set of brushes 9 .. 12 on the commutator of a rotary transformer 1, so that by moving these brushes from their normal position midway between the ordinary fixed brushes 5 .. 8 in either direction, the voltage applied to the motor armature is varied in magnitude and direction to give a variable-speed drive. The brushes 9 .. 12 are moved either by hand or power, and sparking is prevented by employing a commutator of large diameter, and large number of segments, extending the commutator axially, and employing long lines of narrow brushes, making the field as strong as possible, and using a small number of armature turns. A cam or the like is provided for lifting and short-circuiting the movable brushes in their normal position, so that the motor may be brought quickly to rest. In addition, an electromagnetic brake is provided to become effective when the current taken by the motor is below a certain value. A mechanically-driven generator may be used instead of the rotary transformer, and the invention is stated to be applicable to seriesparallel combinations of motors, and to alternating- current commutator machines.

Title: Manufacture of glyoxal-semi-acetals
IPC: C07C45/29
Filed: 1936-03-02
Abstract: Glyoxal semi-acetals are produced by oxidizing compounds having the grouping <FORM:0458000/IV/1> where R is a hydrocarbon radicle, preferably alkyl or aralkyl, by means of an oxidizing agent suitable for splitting a -glycols, such as lead tetra - acetate.  In an example, glycerol aldehyde-diethyl acetal in benzene is mixed with lead tetra-acetate, the lead salt being filtered off after 2 hours and the benzene being distilled off together with formaldehyde and acetic acid.  The residue is dissolved in ether, acid being neutralized with potassium carbonate, and the ethereal solution is then dried with sodium sulphate and distilled.  The Specification as open to inspection under Sect. 91 includes an example in which the tetra-ethyl acetal of dioxy-succinic-dialdehyde is treated as described above, two equivalents of the glyoxal semi-acetal being formed without by-products.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to electrostatically controlled arc discharge devices

Filed: 1956-02-29
Abstract: 844,155. Thermionic valves. BRITISH THOMSON-HOUSTON CO. Ltd. Feb. 25, 1957 [Feb. 29, 1956], No. 6340/56. Class 39(1). An electric discharge device, e.g. a thyratron, containing hydrogen is provided with a reservoir of hydrogen within the envelope from which hydrogen is releasable on heating and electric heating means, controlled by a thermostat, are provided to maintain the reservoir within a predetermined range of temperature so as to provide a substantially constant release of hydrogen from the reservoir whilst the device is in operation. The reservoir 5 may consist of a strip of palladium or titanium, in which hydrogen is absorbed, and which is heated directly by the passage of current therethrough, or a hydrogen containing compound such as titanium hydride held in a container heated by a separate heating element. The thermostat comprises a bimetallic strip 9 which, when cold, engages contact 10 so that resistance 14, which may be a barretter, is shunted through resistance 15. When the temperature of the reservoir 5 rises sufficiently to bring it within the predetermined range the strip 9 bends to open the contacts and the heater current is reduced. The current-limiting impedance may be fitted inside or outside the device and the bimetallic strip may be mounted independently of but near to the bulb 6. The current limiting impedance may be arranged in two or more parts, each to be short-circuited as required by a separate thermostatic device, e.g. to provide rapid initial heating of the reservoir. The thermostatic device may be made responsive to changes in supply voltage by being furnished with a heating winding connected to the same source as the heater for the reservoir. Some form of thermal " slugging " may be associated with the thermostat to give a time delay in heating and cooling.

Abstract: 1326519 Making pipe bend sheaths G MULLENDER 10 Feb 1972 [15 Feb 1971] 6364/72 Heading B3A [Also in Division F2] A pipe bend sheath, for covering thermal insulation for example, comprises a piece of flexible sheet material formed so as to have two stable shapes: a closed shape corresponding to a pipe bend and an open shape in which the longitudinal profile is arcuately corrugated and has the shape of a sector of a hollow body of open-ended hour-glass formation. The sheath is reversably resiliently deformable from one shape to the other. As shown in Figs. 1(a)-1(c) the sheath in the open shape has curved end portions 3, 4 joined by a "saddle" portion 2. The longitudinal edges 1, 5 form the ends of the sheath when the ends 3, 4 are brought together around a pipe bend into the closed shape (Fig. 2(a)-2(c), not shown) and the "saddle" portion 2 springs through to the other side of the peripheries 7, 8 of the enlarged portions 3, 4 to form the inner part of the bend. An extra portion L4 on one curved end 4 produces an overlap in the closed shape on the outside of the bend. As shown in Figs. 3(a)-3(c), a plurality of sheaths may be cut from an embossed sheet which is pressed or moulded from a planar sheet of plastics or metal foil. The embossed sheet has transverse corrugations 30, 32 and longitudinal corrugations 31, 33. Thus, there are produced longitudinal rows of convex hills 34, 37 and concave valleys 35, 36 which have quarter-circle profiles interconnected by straight sections 42, 43 in transverse section. The straight sections 42, 43 correspond to straight end portions L1, L2 of the sheath, Fig. 1(a)- 1(c). The sheet is cut along the dotted lines to produce strips (Fig. 4, not shown) and individual sheaths are produced by cutting the strips across at the appropriate part of the hills 34, 37. Alternatively, the sheaths may be produced from a tube having alternate bulge and neck portions which are quartered longitudinally and cut transversely through the bulged portions.
