Patent GB-1340591-A (GB)
Title: Ribbons
IPC: D04B21/12
Filed: 1971-04-29
Abstract: 1340591 Warp knitting ELASTELLE PAUL FONTANILLE & FILS 29 April 1971 [30 April 1970] 12235/71 Heading D1K A warp knitted fabric having laid-in elastic warps has an edge band A or bands in which transposition of an elastic thread or threads to a different wale and back again at intervals results in a scalloped edge. The basic fabric comprises non-elastic warps 1 joined by periodic transfer or non-elastic wefts 4. The edge band of e.g. 2 or 3 wales is joined to the main band P by e.g. a laid-in weft 4a. Elastic laid-in warps 3 in the band P and edge warp 7 are knitted under the same tension. Warp 8 is at a lighter tension and fed in at such a rate that the length per unit length of fabric, at rest, incorporated is greater than the corresponding unit length of warps 3 and 7. Either or both elastic warps 7 and 8 are transposed at intervals e.g. courses M 2 , M 11 . The weft 4b joining the two wales of band A may be eliminated, therefor the scallop hooks are joined to the bands at the transpositions only.

Title: A process for the working up of iron ores and the like by agglomeration in a rotary tubular furnace
IPC: B60L9/26
Filed: 1935-04-24
Abstract: In a process for treating iron ores and other iron-containing material in a rotary furnace for the production of lumpy iron, the reduction of the iron oxides &c. and the sintering of the sponge produced is effected by the addition of solid fuel in considerable quantity, e.g. about 20-30 per cent, but without or practically without an external supply of heat such as a heating flame or preheating of the reaction air, the reduction preceding the sintering taking place in a long zone in the furnace.  The iron is converted into lumps by the introduction of oxidizing gases at the delivery end of the furnace; the particles of sponge, burnt by contact with air being again reduced by the fuel still present in the furnace so that the agglomerate produced consists of a slag poor in iron in which the lumps are embedded.

Patent GB-455648-A (GB)
Title: Improvements relating to the recovery of ammonia from coal- and like gases
IPC: C01C1/12
Filed: 1935-04-26
Abstract: In the recovery of ammonia from ammoniacal liquor, part of the ammonia is distilled off together with the whole of the carbon dioxide to form ammonium bicarbonate, and carbon dioxide is passed into the liquor containing the remaining ammonia to produce a liquor equivalent to the original liquor which is then returned to the process.  The distillation is effected by steam, the supply of which is adjusted so that the molecular ratio of ammonia to carbon dioxide leaving the still is 1 : 1.  The gases are cooled and washed in a scrubber, preferably by spraying, with a saturated solution of ammonium bicarbonate, crystals of the latter then being deposited in the scrubber.  The liquor remaining in the still may be treated with steam in a second still, with or without the addition of lime, a concentrated ammonia solution being obtained.  The latter may be used for scrubbing the crude coal gas, to give an ammoniacal liquor equivalent to the starting liquor.

Title: Improved Method and Apparatus for Balancing the Axial Thrust in Impulse-reaction Turbines.
IPC: F01D1/16
Filed: 1917-09-04
Abstract: 110,159. Akt.-Ges. Brown, Boveri, et Cie. Sept. 27, 1916, [Convention date]. Balancing moving parts.-Relates to turbines having a high-pressure impulse wheel and a lowpressure reaction part, and consists in wholly or partly balancing the end-thrust of the reaction part by producing on the side b of the impulse wheel a pressure greater than that on the inlet side c. To obtain this pressure difference, the usual equalizing passages in the impulse wheel or casing are dispensed with, and steam is caused to flow from the side c to the side b by the ejectorlike action of the steam from the nozzle e. Steam may also be allowed to escape from the side c through a throttled aperture, such as the labyrinth packing a. To maintain the pressure difference, packings may be built in between the casing and the shroud of the running-blades.

Filed: 1941-10-10
Abstract: 550,967. Opening packages. WINGFOOT CORPORATION. Oct. 10. 1941, No. 13096. Convention date, April 9. Drawings to Specification. [Class 94 (i)] A teasing-strip for use with, or attachment to, a wrapper consists of a ribbon of rubber hydrochloride the tensile strength of which is greater in a longitudinal than in a lateral direction. Preferably the tape is composed of several layers of stretched ribbon which have been united by heat and pressure. The ribbon may be made by passing several strips of rubber hydrochloride film over heated drums and then stretching the strips and pressing them together as they leave the drums to produce laminated ribbons. Instead of using a laminated material, a ribbon may be made by stretching a thick film to give a tape of the required thickness and strength. In another method, a rubber hydrochloride film may be stretched and then twisted or rolled while it is heated, contacting surfaces being pressed together to make them adhere to produce a thread-like structure. Specification 497,788, [Group V], is referred to. The tearing-strip is intended particularly for use with a wrapper of rubber hydrochloride film, but it may be used with wrappers of paper or other material. Methods of using the tape are explained in the Specification.
