Title: Improvements in or relating to Extensible Coiled Airlines
Inventor: MOSS TREVOR FREDERICK
IPC: B60T17/04
Filed: 1967-03-03
Abstract: 1,162,431. Extensible plastics air pipe; pipe connections. T. F. MOSS. 28 Feb., 1968 [3 March, 1967], No. 10170/67. Headings F2G and F2P. An extensible airline, e.g. for braking systems in articulated vehicles, comprises a helically coiled tube 1 of thermoplastics material having a metal coil spring 2 located therein at one, or at each, end and extending partially along the airline, the coil spring 2 preferably having a variable rate. As shown, the spring 2 extends from each end of the tube partially along the airline the two coils being connected by a resilient wire 9 and having more closely wound outer turns and inner ends which are tapered at 4. Due to the presence of the resilient wire 9 the tube 1 can be made of comparatively soft thermoplastics material, e.g. polyurethane, nylon, polypropylene. The innermost ends of the spring may be upset to converge asymmetrically. An end fitting, Fig. 2, comprises a cylindrical member having a larger diameter portion 11 with ribs 12 to engage the inner surface of the tube 1 and a spigot 13 over which an end of the coil spring 14 fits. A sleeve 15 is shrunk over the end of the pipe.
Patent GB-454577-A (GB)
Title: Improvements in or relating to the manufacture of halogen derivatives of methane
IPC: C07C17/093
Filed: 1935-04-02
Abstract: Flurochloromethanes are made by reacting on carbon disulphide simultaneously with fluorinating and chlorinating agents.  Carbon disulphide vapour may be passed through a molten mixture of antimony pentachloride with antimony tri- or penta-fluoride or chlorofluoride, or passed with hydrogen fluoride through a melt containing antimony pentachloride and, if desired, antimony fluorides.  The gaseous reaction product is subjected to fractional condensation, or condensation followed by fractional distillation to separate the constituents.  The melt can be regenerated.  Conditions are preferably regulated to give a product which is mainly CC12F2 together with some CC13F rather than CC1F3 since the monofluoro compound is more easily converted to the difluoro.  In an example, a current of nitrogen containing carbon disulphide is passed into a melt consisting of equal weights of SbC15 and SbF3 kept at 120 DEG C.  The exit gases are condensed at -- 75 DEG  C. and the condensate fractionated.  Carbon disulphide is returned, the remaining condensate being mainly CF2C12 with some CFC13.

Abstract: 739,542. Coke-oven doors. KOPPERS GES., H. April 12, 1954 [May 26, 1953], No. 10728/54. Class 55 (1). In a door handling machine for horizontal coke ovens, the door lifting claw levers 4, 5 and the latch operating mechanisms 47, are mounted on a carrier frame 6 which is mounted on the travelling crab 17, 23, 24 in such manner that, if distortion and sinking of the main trackway of the door handling machine would normally cause the carrier frame 6 to be inclined to the perpendicular, the frame may be restored to perpendicularity. This prevents damage to the door seal means when removing and applying the door. The travelling crab 17, 23, 24 is supported by wheels 18, 20 on tracks 19, 21 and is steadied at its lower part 24 by rollers which bear on a guide. The carrier 6 is pivoted at top and bottom in bearings which incorporate rocking ball or roller bearings, the necessary clearances being provided to permit the compensating adjustments of the carrier to be made without affecting the ability to pivot the frame around, with the door, after it has been withdrawn from the oven. These adjustments are made by arranging the bearings in the part 24 to be slidably adjustable both axially of the oven chamber and transversely thereto, the axial adjustment being effected by a screwed spindle 46 and the transverse adjustment by another spindle (not shown). The drive to the pivot shaft in the upper part 17 of the crab, is through a flexible coupling which effects an automatic uncoupling in the event of an overload. The claw 10 of the lower arm 5 is independently adjustable along the arm.
