Patent GB-409030-A (GB)
Title: Improved manufacture of high-molecular oxygen and thio ethers
IPC: C07C41/00
Filed: 1932-10-26
Abstract: Oxygen and thio ethers useful as softening agents for textiles and lacquers are obtained by condensing (a) monomeric aliphatic compounds, having more than eight carbon atoms, or hydroaromatic compounds which contain a mercapto group or only one hydroxy group but no free carboxylic group with 1 : 2-propyleneoxides substituted in the methyl group by halogen or a hydroxyl or mercapto group and (b) monomeric aliphatic compounds having more than eight carbon atoms or hydroaromatic compounds which contain two hydroxy groups but no free carboxylic group with 1 : 2-propylene oxides substituted in the methyl group by a hydroxyl or mercapto group.  In examples: epichlorhydrin is condensed with dodecanol and cyclohexanol in the presence of sulphuric acid as etherification catalyst.  The samples relate to products obtained by condensing the following pairs of components: naphthenyl mercaptan (mixture) and epichlorhydrin, dodecylmercaptan and epichlorhydrin, dodecyl alcohol and thioglycide, dodecyl alcohol and glycide, dodecyl alcohol and epichlorhydrin.  The last two components yield a mixture of products containing (d -chlor-b -oxy-n-propyl) dodecylether and d -chlor-b -(d -chlor-b -oxy-propyl) propyl dodecylether.  The naphthene mercaptan mixture required for one of the samples may be obtained by sulphonating naphthene alcohols, treating the resulting sulphuric esters with sodium disulphide, and reducing the mixture of naphthenyl mercaptans with zinc dust and glacial acetic acid.  Paraffin and resin alcohols and epibromhydrin and derivatives of fatty acids which contain hydroxy or mercapto groups such as esters are specified.  The Specification as open to inspection under Sect. 91 comprises also the condensation of epichlorhydrin with aliphatic compounds containing more than eight carbon atoms or hydroaromatic compounds which contain two hydroxy groups.  In an additional example, epichlorhydrin is condensed with 1 : 10-dihydroxydecane.  This subject-matter does not appear in the Specification as accepted.

Title: Processing of silicon-iron sheet materials
IPC: C21D8/12
Filed: 1975-07-17
Abstract: 1519191 Silicon steel: heat treatment GENERAL ELECTRIC CO 17 July 1975 30013/75 Heading C7A Grain-oriented silicon-iron sheet is produced from a hot-rolled band containing by weight: 2À2-4À5% Si 3-35 p.p.m. B 30-70 p.p.m. N with the ratio of N:B ranging from 1:1 to 15:1 and the ratio Mn:S being less than 1:8 by annealing to effect at least partial recrystallisation, cold-rolling to final gauge without an intermediate anneal, and finally annealing to produce a (110) [001]texture. It is at the final annealing stage that the Mn:S ratio is critical and additional sulphur may therefore be added by diffusion from the annealing atmosphere or separator to obtain the desired value. In a modification sulphur may be partially or wholly replaced by selenium. Partial recrystallization may be brought about by annealing at 800-1000‹C for 1-3 minutes in hydrogen.

Abstract: 650,519. Washing and drying machines. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 19, 1948, No. 30151. Convention date, Nov. 20, 1947. [Class 138 (ii)] [Also in Group II] A clothes washing machine having a unitary structure comprising a spin basket 4, an agitator 6 in the basket, a sealed casing 7 containing a motor and gearing for operating the basket and agitator, includes yielding means supporting the unitary structure in a tub 1 with the basket spaced from the bottom thereof to provide a space below the basket and surrounding the sealed casing for holding washing solution, and damping means carried by the casing and positioned to co-operate with washing solution in the tub during a spin cycle for damping vibration of the unitary structure. In Fig. 1 the damping means comprises a cylinder 22 carried by arms 23 extending outwardly from the casing 7. On the upper end of the cylinder 22 is a projecting wiper 24 formed from rubber or other suitable material and which engages the inner surface of the tub whenever the amplitude of the vibrations exceeds a given amount. The cylinder 22 may be provided with openings 25 which decrease the damping effect of the cylinder. In Fig. 2 (not shown), the damping means is in the form of a truncated cone while in Fig. 3 (not shown), instead of being a complete ring it comprises several sections. Fig. 4 shows a modification wherein the damping means comprises pistons 40 carried by arms 41 fixed to the casing 7 and fitting loosely in cylinders 42 attached to the tub wall. The cylinders may be provided with openings 43 for inward and outward flow of washing solution due to the piston movement. The unitary structure is supported in the tub by a base spring 10 and three side springs 11. The lower end of the casing 7 stands in an opening 14 in the bottom of the tub and the space between the casing and the bottom is sealed by a flexible diaphragm 15 of e.g. rubber. The diaphragm holds the. casing 7 against turning and may be made stiff enough to support the unitary structure in part or entirely. The tub 1 is provided with two draining outlets, one (21) at the bottom of the tub and the other (18) at a point sufficiently below the basket 4 to provide space for holding the liquid extracted from the clothes. Specification 649,232 is referred to.

Abstract: 292,410. Regenerative Coal Gasification System, Ltd., and Travers, M. W. Nov. 11, 1927. Producers.-A gas generating plant of the kind described in Specification 210,356 is modified by arranging the carburetting chamber in series with the regenerating chamber, so that the whole of the blow gas passes from the latter chamber through the former and then through a superheating chamber. During the blow, the gas passes from the gasification chamber B through the regenerator D, carburetter E and by pipe J to a preheating chamber C and out through the stack valve S. During the run, mixed water gas and distillation gas from the retort A passes through the main H, and a portion is withdrawn and passed by a blower G through the chamber C to the chamber D, from which part of the gas returns to the shaft B and part passes through the carburettor E to a wash box M cooler O and through valve P to the main H. In a modification the preheating chamber is arranged between, and in open communication with the carburettor E and wash box M. and in such an arrangement an additional preheating chamber may be provided.

Abstract: 1305818 Determining rheological propertus of rubber & plastics JAPAN SYNTHETIC RUBBER CO Ltd 25 June 1970 [27 June 1969] 30947/70 Heading G1S An elastomeric sample 13, Fig.2, is pressed by an air chamber/between heated dies 11, 12. The lower die 12 is oscillated thro a zero position to (+) max and (-) min positions by a motor rotated gear wheel 20 and eccentric connecting linkage 18, 18<SP>1</SP> see also Fig. 6 (not shown) so that deformation of the sample takes place for a certain amplitude and produces a phase lagging torque which is registered by a load cell 8, Fig. 1. The angle of lag D 1  to F 1  between torque and deformation is called the dynamic loss angle and is measured and used to determine the quality of the sample. A known recording device 32, Fig. 3, has a driven cord 35 supporting a pen holder with a contact 46 making a fixed contact 47 when a condition of zero torque applies, and contacts 44, 45, Fig. 2, are arranged to make by a cam on wheel 20 when a condition of zero deformation holds. These two circuits are connected to an event marker 38 which records by pulses the position of D 1  F 1 ; D 2  F 2  on paper 40. This known recording system was very wasteful of paper 40 as it is only necessary to know the D & F positions without drawing the complete curves. In the present apparatus the gear 20 and a drum 26 rotate together and an event marker 28 is moved by a motor 31. A pen 27 traces a helical path over the drum paper but is only operated to mark a peripheral line on the paper when the deformation is zero, and is moved out of contact when the torque is zero, so that the pen is only in contact between the zero deformation point and the zero torque point, that is over the dynamic loss angle. If the drum is circumferentially marked say 360 degrees for every revolution, then the dynamic loss angle is indicated by that part of a revolution marked by the pen 27.
