Patent GB-647059-A (GB)
Title: Stretching and laminating film
IPC: B29C55/08
Filed: 1947-08-06
Abstract: A continuous film or sheet of plastic material is stretched by continuously passing the sheet through a heating zone of limited width bordered on each side by a zone of lower temperature, and progressively stretching the sheet laterally as it passes therethrough, thereby bringing the side portions of the stretched sheet into the zones of lower temperature so that they become cooler and their tendency to stretch further is diminished.  The films or sheets may be composed of rubber hydrochloride, cellulose esters, or polyvinyl compounds.  Plasticizers, dyes, or pigments, may be included in the composition of the film.  The process results in uniformly stretched films and sheets.  The film may be passed through an oven by means of travelling devices which grip it at the edges and stretch it laterally while it is in a heat-softened state.  Heated air may be passed through the oven and baffles may be provided to regulate the air currents and control the temperature. Alternatively, the film may be stretched laterally while passing through a heated liquid.  The stretched film may be laminated with other film layers while it is still hot from the stretching operation.  For carrying out the process, apparatus is described which is substantially the same as that described in Specification 647,054.ALSO:A continuous film or sheet of rubber hydrochloride or other thermostretchable material is stretched laterally by continuously passing the sheet through a heating zone of limited width bordered on each side by a zone of lower temperature, and progressively stretching the sheet laterally as it passes therethrough, thereby bringing the side portions of the stretched sheet into the zones of lower temperature so that they become cooler and their tendency to stretch further is retarded.  Plasticizers, dyes or pigments may be included in the composition.  The process gives a more uniformly stretched sheet.  The sheet may be passed through an oven by means of travelling gripping devices which diverge so as to stretch the sheet laterally while it is in a heat-softened state.  Heated air may be passed through the oven and baffles may be provided to regulate the air currents and control the temperature. Alternatively, the film may be stretched laterally while passing through a heated liquid.  The stretched film or sheet may be laminated with other films or sheets, while it is still hot from the stretching operation.  The temperature used for stretching may be 75-110 DEG  C.  The sheet may be stretched to as much as 800 per cent of its original width.  For carrying out the process, apparatus is described which is substantially the same as that described in Specification 647,054.

Title: Improvements in or relating to change-speed power transmissions for vehicles, such as agricultural tractors
IPC: F16H61/02
Filed: 1954-07-23
Abstract: 749,229. Change-speed control. INTERNATIONAL HARVESTER CO. July 23, 1954 [Aug. 17, 1953], No. 21560/54. Class 80(2) A lever 101, controlling engagement of a direct-drive friction clutch 63 of an auxiliary direct-reduced planet gear 13 arranged between the usual main clutch 27 and a direct-reduced countershaft-type main change-speed gear 36 on an agricultural tractor, is moved anti-clockwise to direct-drive clutch release position by depression of the main clutch pedal 92 independently of its own hand lever 102, so that, when the main clutch pedal 92 is depressed during a shift in the main countershaft gear 36, the conjoint release of the auxiliary direct-drive clutch 63 (if engaged) relieves the countershaft gear wheels of that torque which would otherwise persist due to reaction of the road wheel tyres and the use of a one-way overrun detent 73 which normally prevents reverse rotation of the auxiliary gear planet carrier 61 to introduce reduced drive on release of the direct-drive clutch 63. The auxiliary gear comprises in put and output suns 56, 33 and the reversedetained stepped planet carrier 61 connected to input through the direct-drive clutch 63. The direct-drive clutch lever 101, pivoting at 86a, has lost-motion connections at its opposite ends with a main-clutch actuating lever 91, rocked about a pivot 86 by the clutch-pedal 92, and with the auxiliary gear control lever 102, which is spring-loaded to the direct-drive position and is latched by a releasable detent 115 in a rearward position (shown dotted) for reduced drive. Thus either the clutch pedal 92 or auxiliary gear control lever 102 can disengage the direct-drive clutch 63 without affecting each other.

Patent GB-807501-A (GB)
Title: An improved method of producing olefinic compounds
Inventor: LEPRINCE PIERRE
IPC: C07C1/30
Filed: 1955-07-29
Abstract: Olefines are prepared by the dehydro-chlorination of the corresponding chloro-compound by heating with a metal salt dehydrochlorination catalyst in the presence of a polar organic solvent or organic solvent boiling above 140 DEG  C., the reaction mixture forming a homogeneous liquid phase, and removing the hydrogen chloride and olefine as they are formed.  Olefines, cycloalkenes and aromatic compounds containing an olefinic double bond in a side-chain, e.g. styrene, may be thus prepared.  In examples, the dehydrochlorination of monochlorocyclohexane to cyclohexene is described.  Solvents referred to are organic acids such as acetic, propionic, butyric and benzoic acids; aromatic nitroderivatives such as nitrobenzene; alkyl-phenols, decahydronaphthalene, aromatic chlorinated compounds such as ortho-dichlorobenzene and chloronitrobenzene, and high-boiling polar compounds such as dichloracetic acid and trichloracetic acid.  Catalysts referred to are metallic halides, e.g. ferric, aluminium, antimony, manganese, zinc and stannic chlorides.  The process can be carried out continuously by introducing the chloro-compound into the heated mixture of solvent and catalyst at a rate to maintain the reaction volume constant and continuously removing by distillation the olefine and hydrogen chloride. Batch operation may also be used.
