Abstract: 335,139. British Celanese, Ltd. Jan. 12, 1929, [Convention date]. Liquids, treating with.-Knitted fabrics composed wholly or partly of cellulose acetate or other organic derivatives of cellulose are treated with a shrinking-agent such as nitric acid. The treatment reduces the tendency of the fabrics to develop faults such as laddering, running, or splitting, while the treated fabrics have a somewhat reduced lustre. The fabric may contain silk, cotton, or reconstituted cellulose in addition to the organic derivatives of cellulose, and the nitric acid may be applied over the whole surface of the fabric by immersing, brushing, spraying, or padding. The Specification as open to inspection under Sect. 91 (3) (a) describes also the treatment of woven fabrics to prevent " slipping." This subject-matter does not appear in the Specification as accepted.

Title: Lubricating oils
IPC: C10L1/14
Filed: 1953-01-16
Abstract: A lubricating composition, suitable for addition to the gasoline used as fuel in two-stroke engines, comprises a major proportion of mineral lubricating oil, 1-5 per cent by weight of wool-grease and 1-5 per cent by weight of a C10-C20 fatty acid or an ester of such an acid, the ester being derived from a monohydric alcohol.  Suitable esters are esters of C1-C5 monohydric alcohols, such as isopropyl alcohol. The lubricating composition may also contain an antioxidant such as diphenylamine, dicyclohexylamine, naphthylamine, phenylethanolamine, monomethylaniline and dimethylaniline.  The woolgrease imparts to the composition the property of absorbing aqueous acidic materials formed by combustion of the fuel, while the fatty acid or ester thereof increases the adhesion of the lubricating oil to the metal surfaces of the engine, thereby reducing corrosion. In the example, a lubricating composition consisting of mineral lubricating oil, woolgrease and the mixed isopropyl esters of C10-C20 fatty acids sold under the name "Vistone B-12" (the word "Vistone" being a Registered Trade Mark), with or without diphenylamine, is added to a gasoline of high sulphur content.

Title: Improvements in or relating to the vulcanization of rubber
IPC: C08K5/17
Filed: 1931-01-15
Abstract: Rubber is vulcanized in the presence of a salt of an organic amine, together with an organic accelerator of a different class. Organic amines used are preferably of the aliphatic series, and examples are methylamine, benzylamine, dibutylamine, trimethylamine, piperidine, and methyl propylamine.  The salt-forming acids are preferably aliphatic acids of low molecular weight, which gives products such as dimethyl ammonium acetate, butyl ammonium oleate, piperidene butyrate, &c.  Suitable classes of accelerators to combine with the above ammonium salts are guanidines, thioureas, mercaptothiazoles, dithiocarbamates, thiuram sulphides, and thio acids.  Aldehyde amines are in general less successful than the above classes.  The combined effect of the ammonium salt and the other organic accelerator is greater than the sum of the two effects used separately as shown by examples in the Specification.  Specifications 196,924, [Class 70, Indiarubber &c.], and 362,862 are referred to.

Abstract: 1500991 Transistor switching circuits RANSBURG CORP 14 Jan 1975 [14 Jan 1974 (2)] 1628/75 Heading H3T [Also in Division H2] To determine whether the rate of change of an input signal (from terminal 26a) exceeds a threshold, the signal level during a first time interval is stored (28, 29), and the signal level during an immediately succeeding time interval is then subtracted (32) from the stored level to determine whether the difference exceeds a threshold, the store-subtract sequence taking place repetitively. Clock pulses derived from the mains supply render transistors 57, 58 conductive alternately, and these in turn render transistors 61, 62 effective alternately to amplify the input signal. The load circuit of transistor 62 includes a storage capacitor 66, whilst the output of transistor 61 is inverted so that the signals from the two transistors are subtracted at the input of amplifier 73. A monostable 79 is triggered if the amplifier output exceeds a threshold.

Abstract: 571,036. Magnetic tests and measurements. SPERRY GYROSCOPE CO., Inc.. Jan. 28, 1944, No. 1638. Convention date, Jan. 28, 1943. [Class 37] A portion of the core of a flux valve is subjected to an exciting magnetic field, the axis of which moves with respect to the core and which is adapted to produce a high degree of saturation. The core 2, which may be laminated, has a central annular portion 4 and laterally extending portions 6, 7 carrying pick-up coils 10, 11. Fitted into the central opening of the core 2 is a slotted core 8 wound with a threephase two-pole winding 9. This is connected to a source of three-phase current so as to produce a rotating magnetic field in the annular portion 4 of the core. This produces a zone of saturation which rotates with the field. The cross-sectional area of the annular portion 4 of the core diminishes from near the junction with the legs towards the transverse axis a-a, so that the response of the flux valve to the detected field will be varied with time in a sinusoidal manner so as to maintain the output signal substantiallyfree from harmonics. Collector horns 12 may be mounted on the ends of the core and secured by screws T3. A three-phase output for use as a compass system or for controlling a gyro-magnetic compass may be produced by the arrangement of three flux-valves at 120 degrees apart, the output coils being star-connected.

Abstract: 1485691 Continuous steel production FRIED KRUPP GmbH 15 Jan 1975 [16 Jan 1974] 1767/75 Heading C7D In a continuous process for producing steel from particulate iron ore the latter is pre-heated and partially reduced in a counterflow heat exchanger, and is then further reduced to sponge in a fluidized bed by gases evolved in a subsequent melting-refining operation. After separation from the reducing gas the ore is conveyed pneumatically to a melting vessel where it is introduced below the surface of carbon-containing iron bath together with carbonaceous matter, oxygen, and possibly lime and other additives. In a particular embodiment the ore is pre-heated in vessel 1 by waste gases from the fluidized bed reactor 3 augmented by part of the effluent gases from melting vessel 4 which are stored in gas holder 29. Gases leaving the pre-heater are burnt in combustion chamber 6 with oxygen from source 8 and passed to heat exchanger 7, where they heat a stream of co-rich reducing gas from holder 29 in order to maintain a temperature of 500-850C in the reactor 3, to which the pre-heated ore is conveyed in a stream of reducing gas. Sponge iron is separated from gas in the cyclone 11, mixed with carbonaceous matter from source 14 and injected in a stream of reducing gas through the central passage of tuyere 15 into bath 16. Oxygen containing lime from hopper 19 is injected through the intermediate passage, and further carbonaceous matter through the outer passage. A molten intermediate metal is tapped and finally refined to steel by blowing with oxygen in vessel 24.
