Title: Phenolic resin fibres and production thereof
IPC: D01F6/76
Filed: 1972-03-22
Abstract: 1385502 Phenolic resin fibres CARBORUNDUM CO 22 March 1972 [31 March 1971] 13443/72 Heading B5B In an infusible cured phenolic resin fibre, at least 50% of the phenolic hydroxyl groups of the resin are blocked by esterification or etherification. Preferably at least 90%, and especially substantially all, of the said phenolic hydroxyl groups are blocked, suitably by replacement of the hydrogen atoms of said groups with acyl or alkyl having 1 to 6 carbon atoms. Cured novolac resins are preferred, especially condensation products of phenol and formaldehyde. The fibres may be made by reacting an infusible cured phenolic resin fiber with an esterification or etherification reagent selected from anhydrides of alkanoic acids having 1 to 6 carbon atoms, dimethyl sulphate and diethyl sulphate in a liquid environment at a temperature and for a time sufficient to block at least 50% of the phenolic hydroxy groups of the resin. Where dimethyl sulphate is used as the reagent the resin may be converted to the sodium salt prior to the reaction. Where acetic anhydride is used as the reagent, a temperature of at least 100 C. is preferred. The liquid environment may comprise an inert liquid containing the reagent and a catalytic amount of a mineral acid. Where the phenolic resin is highly cross-linked the fibres may be treated with an organic liquid swelling agent, generally a highly polar liquid such as dimethyl acetamide or dimethyl formamide, to assist penetration of the reagent, either as a pretreatment or in the presence of the reagent. The inert liquid may itself function as a swelling agent. A number of other suitable etherification and esterification agents are listed. Fibres so made may be white, and exhibit enhanced oxidation resistance and colour fastness.

Filed: 1957-04-26
Abstract: 820,669. Road-traffic signals on vehicles. CARR FASTENER CO. Ltd. Feb. 28, 1958 [April 26, 1957], No. 13449/57. Class 118 (2). The brilliance of warning or indicator lights of a motor vehicle is controlled by having in the warning or indicator light circuit a resistance with a shunt circuit connected across it, and a bimetallic element in the road light circuit operating to-open said shunt circuit when the road lights are switched on. To indicate to the driver when the direction-indicating lamps 5, 6 are in operation, warning light 1 is supplied from battery 2 via flasher unit 4 and switch means 3 which comprises resistance 8 and contacts 9 capable of short-circuiting the resistance. When switch 14 is closed to turn on road light 13, bimetallic element 11 of switch means 3 is heated by the current and its deflection causes the opening of contact 9, putting resistance 8 in series with warning light 1 and thus reducing its brilliance. Similar means may be used to reduce the brilliance of the direction indicator lights 5 and 6 and the warning lights which indicate to following traffic when the brakes are applied.

An endless warp to be worked in a bobbin net machine is, by reason of a unidirectional movement of the warp carrier, circulated continuously in one direction which is perpendicular to the length of the individual warp threads ; and there are provided for the warp, thread guide devices which are independent of the warp carrier, which are driven in the same direction as is the carrier and which have, in addition, a reciprocating movement to effect the .intertwisting of warp threads and bobbin threads. The warp threads are supplied from an endless row of bobbins 1 continuously driven in the direction of the arrow a, Fig. 3. As these threads pass upwardly, they are separated into two warps 4, 5, Fig. 1, which pass through guide notches 12 of guide rails 10, 11, made up of components borne by links of endless chains 13, 14. The chains are driven and guided by mutually inclined toothed wheels 15, 16. The top runs of the chains, and thus of the rails, run in the same direction as the bobbins supplying them with their warp threads; but on this motion of the rails is superimposed reciprocatory motion. To this end, the wheels 15, 16 are mounted on reciprocatable rails 17, 18. Over the top part of their travel, the rails 10, 11 run with their free edges in slots in a rail 22, and thus the mouths of the notches 12 are closed to retain their warp threads ; but, as the rails pass down over their toothed wheels, known devices 19, 20 transfer the selvedge warp threads from one warp to the other.

Title: Method of pre-stressing the soil more especially for foundations and preferably in a horizontal direction
IPC: E02D27/28
Filed: 1951-06-12
Abstract: 703,654. Concrete foundations. LORENZ, H. June 12, 1951 [June 17, 1950 ; Aug. 12, 1950], No. 13950/51. Class 20 (2). [Also in Group XXI] In forming a concrete pile or foundation the soil at the point of contact with the concrete is consolidated or pre-stressed at least to the point of maximum earth resistance by means of a consolidating device introduced into the concrete before it has set and then increased in cross-section to cause horizontal displacement of the concrete whereupon after setting of the concrete the device is withdrawn and the cavity so formed filled with concrete. In one form the device comprises a perforated tube 3, Fig. 1, surrounded by a rubber jacket 1, the internal chamber 5 of the tube 3 being placed under air or water pressure to expand the jacket 1. Since the earth resistance increases with depth, the tube and jacket may be sub-divided by partitions 8, Fig. 2, and hoops 7, the top chamber 9 receiving the lowest pressure and the bottom chamber 9 the highest pressure, or alternatively the partitions 8 may be omitted and a single pressure medium supply pipe provided having branches fitted with pressure reducing valves leading directly into the jacket sections. In a further modification the thickness of the rubber jacket 27, Fig. 5, increases in upward direction so that a decreasing extensibility is provided in the upward direction in accordance with the decreasing earth resistance, and in this case a pressure fluid of high specific gravity, e.g. a suspension of bentonite and a supplement of heavy spar, is used. Instead of circular crosssection, the device may have an elongated walllike construction for pre-stressing elongated block foundation elements. The point of maximum earth resistance is ascertained by taking readings of pressure and volume of pressure liquid introduced, the point at which the pressure does not increase with increase in volume being the point of maximum earth resistance. Consolidation may be assisted by vibrating the device and/or by introducing a pulsator into the pressure line.
