Filed: 1942-03-18
Abstract: 555,046. Cyclizing hydrocarbons. SHELL DEVELOPMENT CO. March 18, 1942, No. 3609. Convention date, Feb. 27, 1941. [Class 2 (iii)] Aromatic hydrocarbons are prepared by cyclization of aliphatic hydrocarbons having 6 to 12 carbon atoms, using as catalyst a compound of a metal selected from the left hand columns of Groups IV to VI of the Periodic Table, supported on a stabilizing carrier of relatively low catalytic activity, and promoted by the presence of platinum and (or) palladium. The support may be an adsorptive alumina such as alumina alpha monohydrate or "activated alumina." The catalyst, which is preferably chromium oxide and may contain zinc oxide, is impregnated with a solution of a compound of the promoter, e.g. ammonium or alkali platinum chloride or barium platinum cyanide, dried and heated. Sulphates should be absent but a small amount of a potassium compound other than sulphate may be present. Examples give the conversion of heptane to toluene.

Abstract: 100,870. Davies, A. March 13, 1916. Sampling liquids.-Samples of streams of pulp, slimes, wet ores, &c., flowing along a launder 1, 2 are obtained by passing through the stream, either in the direction of flow of the stream or at an angle thereto, a trough 9 of the same width as the stream, the motion of the trough being derived from a tipping-tank 3 supplied with water from a tap 4. Means are provided for obtaining an approximately uniform speed of the trough during its passage through the stream, so as to obtain a sample of the various strata of the stream. In the arrangement shown, the trough 9 is borne by a frame 7 mounted on rollers 8, the frame being connected by flexible members 6 with sectors 5 carried by the tank; so that the speed of the trough at the period of taking a sample is approximately uniform. Instead of the flexible members 6, the sectors may be toothed for engagement with a carriage-operating rack.

Abstract: 940,609. Resilient bushes. ADAM OPEL A.G. Feb. 1, 1962 [Feb. 9, 1961], No. 3804/62. Heading F2S. A resilient bushing 12 for an eye 11 of a leaf spring 10, particularly a semi-elliptic leaf spring, comprises a cylindrical mass having radially projecting, axially extending, ribs of differing strength and thickness which, when the bushing is fitted to the eye, are radially compressed, and a metal sleeve 13 which is bonded within a bore in the bushing. The bushing 12 is made of rubber and the sleeve 13 receives a bolt 14 for securing the spring 10 to a bracket 15 which is strengthened by spot welded discs 19, 20 and is welded to the frame 16 of a vehicle. The bushing has four ribs 23-26 arranged at right angles to each other the vertically aligned pair 23, 24 being considerably thicker and stronger in the circumferential, and radial directions than the two ribs 25, 26 located in a horizontal plane. When the bushing is introduced into the eye 11 the ribs 23, 24 are subjected to considerable compression the bottom rib 23 being thicker than the upper rib 24 so that the sleeve 13 is slightly eccentric with respect to the eye 11. The ribs 25, 26, which lightly engage the eye 11 to offer little resistance to small horizontal movements, are of uniform cross-sectional shape over the length of the bushing, the ribs 23, 24 having an axial cross-section of convex shape. When the bushing is fitted end flanges 27, 28 engage between the sides of the bracket 15 and the corresponding end faces of the eye 11, the flanges being provided with identification tabs 31, 32 as a guide to correct fitting.

Title: Process for the preparation of cross-linked polyurethanes
Inventor: MULLER ERWIN
IPC: C08G18/79
Filed: 1965-01-28
Abstract: High molecular weight cross-linked polyurethanes are prepared by reacting the reaction product of a linear polyhydroxyl compound of M.W. above 1000, water and a less than equivalent quantity of an organic diisocyanate said reaction product having a Defo plasticity of 200-1500, with a quantity of dimeric toluylene 2: 4 diisocyanate in excess of that calculated on the end groups of the reaction product, the polyhydroxyl compound used being a polyester urethane obtained from hexane 1 : 6 diol adipic acid polyester having a MW of 800-1000 and 0.4 to 0.7 mol. per mol. of polyester of an organic diisocyanate.  An aromatic compound containing aliphatically bound -OH groups and having a M.W. below 500 may be added to the reaction mixture.  In an example a hydroxyl terminated polyester urethane of M.W. 2000 prepared from tolylene diisocyanate and hexane 1 : 6 diol adipic acid polyester was mixed with water and tolylene diisocyanate to give a product of Defo plasticity 450. This rollable product was then mixed with carbon black, dimeric tolylene 2:4 diisocyanate and the lead salt of 3 mercapto 1 : 2 : 4 triazole, on cooled rubber rollers.

Title: Improvements relating to the production of hydroxylamine sulphonates
IPC: C01B21/14
Filed: 1951-02-16
Abstract: <PICT:0676090/III/1> In the manufacture of hydroxylamine sulphonates by the reaction of sulphur dioxide - containing gases with ammonium nitrite and ammonium bisulphite or other ammonium compound which forms the bisulphite when in contact with sulphur dioxide, the aqueous solution of the initial ammonium compounds is dispersed in a stream of sulphur dioxide-containing gas and subsequently passed over cooled surfaces together and in concurrent flow with the stream of gas.  An aqueous solution of ammonium hydroxide and ammonium nitrite enters reactor 1 through pipe 2 and is sprayed by distributing ring 3 into gases from sulphide-ore roasting containing 10 per cent sulphur dioxide entering at 4.  The reaction mixture passes down tubes 5, which are cooled by cooling liquor circulating from inlet 6 to outlet 7 and packed with inert filling material, and residual gas is withdrawn at 8 and resultant liquor at 9.  To remove excess sulphur dioxide an inert gas, e.g. air, is passed through the resultant liquor which contains hydroxylamine disulphonate which may be hydrolyzed to monosulphonate and sulphate.  The gas feed is adjusted so that the liquor leaving the cooling tubes has a pH of 3.5.  In alternative apparatus the reaction mixture is passed through a cooled helical pipe or over a series of cooled pipes.

Abstract: 524,674. Electric cables. STANDARD TELEPHONES & CABLES, Ltd., BAGULEY, , E., and LONG, A. L. Feb. 7, 1939, No. 4016. Drawings to Specification. [Class 36] In a multi-conductor telephone cable comprising two or more layers of twisted cores (pairs, quads &c.) enclosed in a lead sheath, the self inductance and A.C. resistance at -carrier frequencies of the circuits formed by the conductors of the outer cores are made substantially the same as those of the inner cores by spacing the conductors of the outer cores farther apart than those of the inner cores, as by using more layers of paper tape, or wider and/or thicker tape. Mutual capacities of the circuits formed by the conductors of the outer cores may be raised to those of the inner cores by using insulation of a higher dielectric constant, as by using different material or changing the ratio of air insulation to solid insulating material such as paper, or by interposing a thin conducting layer at a critically determined position between the cable cores and the lead sheath. The sheath may also be spaced from the cable cores by means of a layer of dielectric of a thickness greater than is necessary for mechanical or electric breakdown requirements. Specification 453,124 is referred to.
