Abstract: 976,019. Air cooled apparatus for condensing vapours. HAPPEL G.m.b.H., [trading as GEA LUFTKUHLERGESELLSCHAFT HAPPEL G.m.b.H. & CO. K.G.]. Feb. 12, 1963, No. 5761/63. Heading B1B. In an air-cooled apparatus for condensing vapours, e.g. the exhaust steam from a turbine, comprising a plurality of tubular downflow condensers 7 connected by pipes 11a to the lower ends of a plurality of tubular reflux condensers 14 at least one fan is provided to cool the downflow condensers 7, and at least one fan 17 is provided to cool the reflux condensers 14, the fans 9 and 17 being controlled independently of one another. The exhaust steam from the turbine passes into distributing pipes 4, which are connected to the upper headers 6 of the downflow condensers 7 via lines 5. The steam passes down the tubes 8 of condenser 7, which are cooled by the air flow from fans 9, and the major portion of steam condenses. The condensate flows through pipes 11a and 11b into a receiver. The uncondensed steam from condensers 7 passes via pipes 11a a and headers 15 into reflux condensers 14, where it is completely condensed, the condensate formed flowing back into pipes 11a to join the main flow of condensate. The upper headers of reflux condensers 11 are connected to an air-suction device 18, such as a steam ejector, so that any oxygen in the steam entering condensers 14 is removed. Thermostats 20, inserted in the lower headers 10 of the downflow condensers or in the condensate collecting pipes 11a, are used to reduce or switch off the power supply to fans 9 when the temperature of the condensate falls below a certain predetermined value. Fans 9 are switched on again when the temperature of the condensate reaches an upper predetermined limit. Fans 17 run continuously as long as the turbine is in operation.

IPC: H02K3/34
Filed: 1957-02-20
Abstract: An insulating material for wrapping electrical conductors comprises an unsupported silicone rubber tape which has been partially cured by heat to obtain the physical characteristics (a) the tape has non-tacky opposite surfaces, (b) the stress strain curve of the tape at room temperature persists with an upward slope from strain equals zero to strain equals 100 per cent, and (c) the partially cured tape will not rupture when stretched 100 per cent and then further heated to 200 DEG  C.  If desired the tape may be coated on one or both sides with an uncured silicone rubber paste.  The preferred siloxane used for the silicone rubber tape is one having a viscosity of at least 106 cs. at 25 DEG  C. and having from 1.9 to 2.0 organic radicals per Si atom, at least 50 mol. per cent of the siloxane units being (CH3)2 Si,O the remainder having the formula RR1SiO wherein R and R1 are each phenyl or an aliphatic hydrocarbon radical containing 1 to 4 C atoms, e.g. methyl, ethyl, vinyl, allyl, n-propyl, isopropyl, n-butyl, sec-butyl, iso-butyl and t-butyl.  Fillers, e.g. fume silica, silica aerogel, diatomaceous earth, ferric oxide, calcium carbonate and titania, and curing catalysts, e.g. benzoyl and halogenated benzoyl peroxides, t-butyl perbenzoate, t-butyl-peracetate and sulphur may be added.  In an example, a composition having a viscosity of 30 X 106 cs. at 25 DEG  C. and composed of a dimethylsiloxane gum, fume silica, ferric oxide and benzoyl peroxide, was milled to a soft puttylike consistency and extruded in ribbon form.  The ribbon or tape was partially cured by passing it through an air oven at 350 DEG  C. and the resulting tape was then coated on both sides with a paste consisting of dimethylsiloxane having a viscosity of 35,000 cs. at 25 DEG  C., calcium carbonate, ferric oxide and dichlorobenzoyl peroxide. Shaped conductors, such as coils, with strand insulation and turn insulation in place were stretch wrapped with the coated tape and covered with a protective wrapping, e.g. glass or other fabric, which may be coated or impregnated with varnish or silicone rubber.  The insulation was compacted, e.g. by means of clamps and moulding strips, and briefly cured, e.g. by passing an electric current through the coil or by baking in an oven, to set the paste.  The insulated coil was then heat cured after removal of the compacting means.

Title: Improvements in or relating to machines for blowing bottles and other hollow articles from organic plastic materials
Inventor: STRONG BERNARD
IPC: B29C49/04
Filed: 1953-03-04
Abstract: 733,671. Blow-moulding hollow articles. SHIPTON & CO., Ltd., E. March 4, 1954 [March 4, 1953], No. 6011/53. Addition to 700,984. Class 87 (2). The parent Specification is concerned with a machine for blowing plastic bottles &c., in which plastic material is extruded in turn through a plurality of blowing nozzles, and in that machine a simple cam operates a hydraulic valve 48 to change the delivery of plastic material from one nozzle to the next nozzle, the same quantity of material being extruded from each nozzle in turn. When moulds of different size were associated with different nozzles sufficient material .was extruded from each nozzle to make the largest article, and the excess extruded at the nozzles having smaller moulds was severed and re-used. In the present invention the quantities extruded at different nozzles are adjusted. to correspond with different sizes of mould. The cam 49 that changes the delivery from one nozzle to another has a plurality of cam surfaces (correspondirig in number to the number of nozzles) the lengths of the respective cam surfaces being determined in accordance with the ratio of the quantities of plastic material to be extruded from the different nozzles. The cam shown comprises a disc 100 having threaded apertures 101 which receive screws 104 that secure cam sections 102, 103 to the disc. As shown, four cam surfaces are thus formed, each cam surface comprising one curved section 102 and one or more straight sections 103. The length of a cam surface is altered by adding or subtracting a section 103. The longer the time during which a cam surface is in contact with a cam follower 105 that operates the hydraulic valve 48, the greater the ratio of extruded material. The actual quantity of materialextruded is adjusted by changing the gear train 50a, 50b between a drive pinion 5<1> and a gear wheel 49<1> on the cam shaft. The gear wheel 50a is mounted in a swingable member 106 that can be locked by means of a nut 107.

Title: Improvements in and relating to the production of mixtures comprising ammonium nitrate and calcium carbonate
IPC: C05C1/00
Filed: 1930-02-24
Abstract: 339,562. Odda Smelteverk Aktieselskabet, and Johnson, E. March 4, 1929, [Convention datel. Manures.-A mixture of ammonium nitrate and calcium carbonate is produced by treating a solution of calcium nitrate, which may be previously concentrated in vacuo, with ammonia and carbon dioxide, or ammonium carbonate or bicarbonate, and removing water, preferably in vacuo, to obtain a granular product, which may also contain calcium nitrate. Excess carbon dioxide may be used. The calcium nitrate solutiun may be obtained by the process of Specification 339,340, or by neutralizing nitric acid with limestone, carbon dioxide evolved being employed as above. Other sources of carbon dioxide are specified. The heat required may be obtained by heating the reaction gases. The process is preferably carried out by passing the reacting gas in countercurrent to the well-stirred solution, in revolving drums. The operation may be conducted in two stages, so that in the first, mainly the chemical reaction occurs, and in the second, water is evaporated. The presence of one or a mixture of the reacting gases, preferably carbon dioxide, in the second stage avoids a reversal of the reaction. Ground limestone may be added to the product at any convenient stage.

[Also in Group XXXV] An improvement in or a modification of the food mixer described and claimed in the parent Specification is characterised in that the power take-off coupling faces upwardly in the pillar, at least one horizontal take-off coupling in the pillar and the drive therefor being embodied in a gear unit which is housed within the pillar but is readily removable from it. The mixer may thus be supplied without the gear unit when it is not required to drive additional appliances. The gear unit 30, Fig. 1, includes a casing 32 having a front wall 33 attached by screws to a removable front wall 31 of the pillar 13. The upwardly facing power take-off coupling 49, which may drive for example, a juicer 65, Fig. 6, is attached to the upper end of a vertical shaft 48 which carries a worm wheel 47 in mesh with a worm 46 on a horizontal shaft 43. The front end of the shaft 43 extends through an opening in the pillar wall 31 and has a power receiving coupling 44 to cooperate with the power take-off coupling 22 on the shaft of the electric motor in the power unit 14. The rear end of the shaft 43 has a high speed power take-off coupling 45 extending into an opening 37 in a recess 35 in the rear wall 34 of the pillar 13. The coupling 45 drives a blender 60, Fig. 6, which has a cylindrical protruberance carrying a resilient ring fitting the recess 35 to frictionally hold the blender unit 60 against the rear wall of the pillar. When the gear unit 30 is not provided the recess 35 is closed by a cover plate 41. The juicer 65 and blender 60 may be operated simultaneously, the juicer having a spout 65 for delivering fruit juice into the blender. A worm 51 on the vertical shaft 48 meshes with a worm wheel 52 on a horizontal shaft 53 terminating in a lowspeed power take-off coupling 54 accessible through an opening 55 in one of the side walls of the pillar. The coupling 54 may drive units such as a meat grinder or a can opener, or a vegetable grinder or slicer which can for example be operated simultaneously with the juicer 65 and blender 60 to add vegetables to the mixture in the blender. The power unit 14 is clamped to the platform 12 by means of a sliding latch 26 which engages a hooked lug 17.

Abstract: A process for the production of compounds having a structural formula <FORM:0727247/IV (b)/1> in which R is either hydrogen or an alkyl group, R1 is an alkyl group and R2 is a secondary alkyl group which may contain an aryl substituent, comprises reductively alkylating the corresponding amines having a structure <FORM:0727247/IV (b)/2> by hydrogenation in the presence of the appropriate ketone, under conditions which do not lead to the occurrence of a substantial amount of nuclear hydrogenation.  The reaction is effected catalytically using a catalyst comprising copper (which may be in foraminate form or on a support such as zinc oxide, alumina, kieselguhr or pumice) or a metal of Group VIII of the periodic system such as nickel (foraminate or Raney form) or platinum (finely divided or on a support).  The reduction is effected in liquid phase, conveniently in a medium of excess ketone, a ketone/amine ratio of 10 : 1 being suitable.  Temperatures of 120 DEG  to 200 DEG  C. and pressures of 25 to 100 atmospheres may be used.  In an example N-dimethyl-p-phenylene diamine (obtained by the catalytic reduction of N-dimethyl-p-nitroso-aniline) is reacted with methyl ethyl ketone and hydrogen at 50 atmospheres and 160 DEG  C. to give N-dimethyl-N1-sec.-butyl-p-phenylene diamine. N-Methyl-N1-(diphenylmethyl)-p-phenylene diamine may be produced similarly by hydrogenating a mixture of N - methyl - p - phenylene diamine and benzophenone.  The products are suitable for the stabilization of organic compounds liable to deterioration arising from free-radical chain reactions propagated by oxidation or polymerization, and may be added for that purpose to aldehydes, ethers, petrols, fatty oils and lubricating oils comprising esters or hydrocarbons, suitably in amounts of 0.0002 to 3 per cent by weight. Specification 508,129 is referred to. According to the Provisional Specification, R1 and R2 may also represent aryl radicals.ALSO:Amine derivatives of the formula <FORM:0727247/III/1> in which R is either hydrogen or an alkyl group, R1 is an alkyl group and R2 is a secondary alkyl group which may contain an aryl substituent are suitable for the stabilization of organic compounds liable to deterioration arising from free-radical chain reactions and for that purpose may be added to petrols, fatty oils of vegetable or animal origin comprising esters of long chain saturated or unsaturated carboxylic acids and lubricating oils comprising esters or hydrocarbons, suitably in amounts of 0.0002 to 3 per cent. by weight. Compounds of the above formula, the preparation of which is described (see Group IV (b)), include N-dimethyl-N1-sec butyl-p-phenylene diamine (shown as an antioxidant for petrol) and N-methyl-N1-(diphenylmethyl)-p-pheny. lene diamine.
