Title: Improvements in and relating to flexible cable and the like transmission devices
IPC: F16C1/26
Filed: 1933-12-14
Abstract: 431,515. Bowden mechanism. SIMMONDS, O. E., and SIMMONDS AEROCESSORIES, Ltd., Shell-Mex House, Strand, London. Dec. 14, 1933, No. 35197. [Class 80 (iii)] The mechanism comprises a flexible outer tube whose outer surface provides a screw thread, in combination with an inner flexible member, e.g. as described in Specification 375,115, having a series of swellings or enlarged parts that contact with the inner wall of the outer tube, or a flexible cable or like means for tension loads and a separate means for compression loads. Where it is not desirable that the whole of the outer tube be flexible, short lengths of the flexible outer tube may be joined, by the screw thread on its outer surface, to rigid tubes. A short length of flexible tube 1, Fig. 1, is formed by coiling a wire of triangular section and the screw-thread so formed is adapted to receive at each end a screwed ferrule 2, 2<1>. The intermediate part 3 of each ferrule is of smooth cylindrical bore of the same diameter as the smooth bore of the coiled wire and of the rigid tubes secured thereto. The thread in each ferrule is formed in an enlarged part thereof and a recess 18 is provided to enable the ends of the flexible tube 1 to fit tightly against the ends of the ferrules. The inner member consists of barrels 4 and tubular elements 5, Fig. 2, but may comprise a cable for tension loads and a helically coiled spring for compression loads. The terminal member 19 may be connected to the end of a rod 6 sliding in a tube 14 and pivotally connected to a lever 9 to be actuated. The ferrule 2 remote from the rod 6 is secured by a clip 8 between collars 7, 7<1> to prevent the rod 6 from applying offset loads to the rigid tube 10. A length of oil-resisting rubber 11 may be placed over the flexible casing 1. To lock parts against vibration, a union nut 12 and tapered ring 13, Fig. 2, may be employed or, as in Fig. 1, a locknut 15 on a rigid casing 16 may be tightened against ferrule 21.

Abstract: 1508097 Cooled furnace walls INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE 26 Aug 1976 [28 Aug 1975] 35456/76 Heading F4B A wall unit for a furnace, particularly an electric arc furnace, comprises a cooled metal block 1 having hangers 3 projecting from its inner face, each comprising a stem 8 and an enlarged head 9 and engaging cavities formed in refractory lining blocks 2. The hangers may be integral with the cooled blocks, the water passages in the block being shaped to improve the cooling of the hangers, or they may be formed as separate elements, the shanks of the hangers passing through the blocks 1 and being secured by flexible means such as nuts and washers. The hangers may have individual cooling circuits, Fig. 2, or a conical metal sleeve 12, Fig. 4, on the shank of the hanger provides good heat transfer between the block and the hanger. The cavities in the blocks 2 may extend right through the blocks, a plug 13 of refractory concrete closing the cavity in the hot face.

Abstract: 488,028. Cutting webs; making machine-knives. JACKSON, D. R. P., and MOLINS MACHINE CO.. Ltd. Dec. 29, 1936. No. 35612. [Class 31 (i)] [Also in Group XXII] In a cutting-device for cutting curved or angular slits 14 in a cellulose derivative web 4, the web 4 is cut by co-operating rotary and fixed blades 13, 8. The blade 8 is straight and the blade 13, which is integral with an arcuate member 9 secured by screws 10 to a reduced portion 7 of a cylinder 6, is of curved or angular form. A guide 27 is provided. The web after slitting passes through guides 21, 22 and rolls 23, 24 to a device comprising fixed and rotary blades 15, 16 which form the cuts 17, 18 overlapping the slit 14 at 19, 20. In making the rotary blade, a cylindrical member having diametrically opposite projections each of the shape of a blade 13 is provided with a bore corresponding to the support 7, is partly divided in two and is then hardened. The bore is then ground exactly to fit a mandrel of the same size as the support 7 and the member secured thereon. The cutting edges are then ground and the member divided into two parts. Specification 165,891, [Class 31 (i)], is referred to in the Provisional Specification.

Abstract: 1,072,808. Cooling systems for electrical apparatus. SOC. GENERALS DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALSTHOM). Sept. 2, 1964 [Sept. 2, 1963], No. 36036/64. Heading F4U. [Also in Divisions Fl, F2 and H2] In an installation which includes a dynamoelectric machine, e.g. alternator 1 having a carcase 3, e.g. a bulb submerged in water, e.g. a river, and containing oil, the carcase interior is so connected by two passages to an oil reservoir 7 above the water level and open to atmospheric air that during operation the oil circulates to continuously extract any water which has penetrated the machine. The passages comprise two pipes 8, 9 of which the former is heat insulated and which respectively enter the upper and lower parts of the carcase to circulate the oil by thermo-siphon effect. The circulation is interrupted when the machine is cold, and may be assisted by a pump. Air circulation in the reservoir may be accelerated by a chimney or a ventilator, and to evacuate a large quantity of water replaceable filter paper, silicagel or molecular screens may be immersed in the reservoir. The alternator is driven by a turbine 6, has a stuffing box 5 and auxiliary circuits 2, and its output and auxiliary cables through the pipe 8.

An automatic turret lathe has an attachment comprising a plurality of workpiece gripping devices 26 on a rotatably mounted head 16 and a device for transferring workpieces to the head for one or more operations to be performed upon them, the head being positioned such that the gripping devices are presented in the same direction as those on the turret 12, and means 14 for indexing the head being actuated by the main actuating shaft 13 of the lathe. The spindle 11 carries six chucks 12a on the turret 12. Some tools are carried on cross-slides 15 and other, end-working, tools are carried on slides 15a. The slides are actuated and the turret indexed from the main cam-shaft 13. The subsidiary four-position work turret 16 is carried on a bar 18 and indexed by geneva mechanism having its roller 14 mounted on the shaft 13 and having a locking plunger 24 controlled by a groove in a cam 25 also on the shaft 13. The plunger engages spring-pressed teeth 23. The collets 26 are actuated by a cam 29 and sleeves 27. The cam also actuates an ejector 30. The collets are thus opened or closed during indexing movements of the turret. Workpieces are transferred in turn from one of the chucks 12a to the upper collet 17 of the turret by means which turn the workpiece through 180 degrees. The workpiece in the collet 17 is then machined by additional tools such as for drilling and tapping a hole in the rear of the workpiece. In a modification, the workpieces are not turned during transfer.
