Title: Improvements in and relating to axle-recording device for railways
IPC: B61L1/16
Filed: 1920-11-25
Abstract: 154,539. Krupp Akt.-Ges., F. Nov. 27, 1919, [Convention date.]. Recording particular operations.-The passage of train axles past treadles on the track is recorded by electro-magnetically-operated apparatus, which records the time and direction of passage and whether each axle is lightly or heavily loaded. The contact treadles each comprise a plate E, H, J mounted on a pivot parallel to the rails D, D<1> and supported near its free end by a spring-pressed plunger F, K, M, the springs being such that any axle depresses the plates E, J, so that contact is made between members fixed to the pivoted member and the base plate, whilst the plate K is only depressed to make contact by a loaded axle. The free ends of the plates E, H, J move in slots in the rail head, which is also cut away below the middle of the edge of the plate H. The recording apparatus comprises a drum Q rotatable step-by-step by a magnet r<1> each time the plate J is depressed. The marking pencils S, S<1> are always in contact with the drum Q and are moved axially bv a clock mechanism T, and so mark a line parallel to the axis of the cylinder. Closure of contacts by the plates E, H causes the pencils S, S' respectively to reciprocate slightly. Thus, if no train passes, a double line parallel to the axis is drawn by the pencils. As each axle of a train passes the plate J, these lines are deflected transversely due to rotation of the drum and short axial lines are drawn by one or both pencils according to the pressure of the axles on the plates E, H. The direction of passage is shown by the relative positions of the axial and transverse marks due to the closure of contacts J before or after the contact E.

Title: Improvements in or relating to the manufacture of varnish resin interpolymers
IPC: C09D125/14
Filed: 1947-12-18
Abstract: A varnish resin is made by polymerizing at temperatures between 120 DEG  and 300 DEG  C. a mixture comprising 30 per cent to 90 per cent by weight of a drying oil, having an average degree of conjugation greater than 25 per cent, but not greater than 35 per cent, and 70 per cent to 10 per cent of a mixture of 50 to 83.3 per cent of a monovinyl aromatic compound having the vinyl group unsubstituted and 50 to 16.7 per cent of an alpha-methylene alkyl aromatic compound, the alkyl group being methyl or ethyl.  Specified drying oils are mixtures of low conjugated oils such as linseed, soybean, dehydrated castor, perilla and fish oils with highly conjugated oils such as tung or oiticica oil.  The monovinyl aromatic compound may be styrene, o- and p-methyl styrenes, o-and p-ethyl styrenes, op-dimethyl and diethyl styrenes, p- and m-chlorostyrenes, o-methyl-and o-ethyl-p-chlorostyrenes and o-methyl-p-isopropyl styrene.  Suitable a -methylene alkyl aromatic compounds are a -methyl styrene, a -ethyl styrene, p-methyl a -methyl styrene, o-, p-dimethyl a -methyl styrene, m- and p-chloro a -methyl styrenes, p-isopropyl a -methyl styrene and m-chloro-p-methyl a -methyl styrene.  Polymerization may be effected as described in the parent Specification.  The interpolymers are soluble in aromatic solvents, e.g. toluene, in mixtures of aromatic and aliphatic solvents, e.g. mineral spirits and somewhat soluble in aliphatic solvents alone. They are compatible with linseed oil, phenolic resins, some modified alkyd resins, rosin-ester, paracoumarone-indene resins, urea and melamine resins.  They may be bodied by heating for several hours above 250 DEG  C., e.g. from 275-295 DEG  C.

Abstract: 1481852 Cameras AGFA-GEVAERT AG 30 July 1974 [31 July 1973] 33584/74 Addition to 1413420 Heading G2A In a camera of the type disclosed in Specification 1413420, in which a member 402 slides on the main housing 401 to cover or uncover components such as the lens and view-finder, at the same time effecting film transport and/or shutter tensioning, a spring 404 is arranged to urge the slider 402 into the open or operative position. As shown, two such springs are provided, the legs 404b being joined at one end by a fork 404e engaging in a lug 402a on the slider 402. The other legs 404a have bent-over ends 404d which engage between lugs 401a, 4016, on housing 401. Thus as slider 402 is moved in the direction of arrow 403 to transport the film and set the shutter, it is moving against the action of springs 404, which tend to move it back to the Fig. 2 position.

Title: Process and apparatus for testing the lubricating value of lubricants
IPC: G01N33/30
Filed: 1937-12-04
Abstract: 497,306. Measuring efficiency of lubricants. VOGEL, H. E. R. Dec. 4, 1937, No. 33643. [Class 106 (ii)] A rotating disc of very great resistance, covered with the lubricant, has applied with a given pressure to its flat surface the fine end of a pin of low wear resistance, the wear of the pin being calculated for example by weighing. A vertical axle 3 carries a disc 4 of very great wear resistance, and rotates in a vessel 1 or thermostat containing oil 5 and into which dips a thermometer 2. An interchangeable needle or pin 6 is fixed to an arm 7 on which is a plate 8 carrying a weight 9 which presses the pin 6 down on to the plate. The change in weight of the pin before and after test is a measure of the wear of the pin. The variation in length taken in conjunction with area of section can also be used. Oils may be tested by taking as lubricating value the ratio of the wear of the pin in a standard oil, say castor oil, to the wear when in the oil to be tested. Instead of one pin, several may be used, the disc may also rest on the pins and serve as a weight. If only a small portion of lubricant is available it may be placed in a groove bored in the disc.

Title: A method of preparing solutions of starch
IPC: C08B30/12
Filed: 1921-12-15
Abstract: In preparing solutions of starch the starchy material is first digested for about twenty hours with a dilute acid solution of potassium bichromate or permanganate, or with permanganate solution alone, the excess oxidizing agent being then reduced, for example, by addition of sulphurous acid.  The product is treated with boiling water and the suspension clarified by addition of an alkaline substance to a concentration of about 0.01 normal.  The last two operations may be combined into one.  Suitable alkaline substances are caustic alkalis, ammonia, sodium carbonate, and borax.

Title: Manufacture of methane derivatives containing chlorine and fluorine
IPC: C07C17/20
Filed: 1931-12-11
Abstract: Fluorochloromethanes are obtained by causing hydrogen fluoride to react on carbon tetrachloride in the gaseous phase and, if desired, under increased pressure, in the presence of a mixture of antimony trichloride and antimony pentachloride.  The mixture of chlorides may be used directly in a fused state or deposited on a carrier such as coke.  According to an example, a mixture of antimony trichloride and antimony pentachloride is maintained at a temperature of 100-130 DEG C. in a copper vessel, while a mixture of hydrogen fluoride, carbon tetrachloride, and a little chlorine is passed in continuously.  The exit gases, containing hydrogen chloride, carbon tetrachloride, fluorochloromethanes, and small quantities of antimony chlorides are first washed in a scrubber with carbon tetrachloride, the liquid obtained being returned to the reaction vessel, then passed through a water scrubber, and are finally condensed at about -30 DEG  C.  The condensate on fractionation yields fluorotrichloromethane and difluorodichloromethane.

Filed: 1965-08-12
Abstract: In a flexible carbonaceous article comprising a plurality of carbonaceous filaments forming a yarn, a majority of the filaments have a coating of pyrolytically deposited carbon on the surfaces thereof.  The filaments are coated by contacting them while heating, e.g. at 1800-2300 DEG  C. under non-oxidizing conditions with a hydrocarbon-containing gas stream, the hydrocarbon having a cracking temperature below the temperature of the filaments. The yarn may be carbon yarn and the hydrocarbon may be methane, ethane, propane or mixtures thereof, preferably also together with argon, hydrogen or helium.  The filaments may be heated by passing an electric current there-through, and in a continuous mode of operation the filaments pass from one conductive reel (e.g. of graphite) to a second conductive reel via a water-cooled coating chamber, wherein the filaments are contacted with the hydrocarbon stream.  Alternatively, radiation or induction heating may be employed.  Silicon or boron vapours may be present in the hydrocarbon stream to give siliconized or boronated, pyrolitic carbon coatings.ALSO:In a flexible carbonaceous article comprising a plurality of carbonaceous filaments forming a yarn a majority of the filaments have a coating of pyralytically deposited carbon on the surfaces thereof.
