IPC: C03B21/02
Filed: 1969-02-14
Abstract: 1,264,363. Producing sealed lengths of glass tube. J. C. HOUDAILLE. 14 Feb., 1969, No. 2076/69. Heading C1M. Glass tubing is separated into lengths with sterile interiors and sealed ends by feeding the continuous, freshly formed tube 14 along driven rollers 3 which are movable in the downward direction on rods 4 when actuated by cams 12 and 13 carried by the chain 11 which moves at the same speed as the glass (rollers 3 being driven at the same speed by chain 2). As each roller is lowered, a series of burners 19, 20, 24 &c. (see Fig. 2, not shown) move downwards to surround the tube at each point at which the roller has been lowered, their motion being actuated by a second pair of cams 16 and 18 on chain 15 which travels at the same speed as chains 2 and 11. The burners each move with the tube for a distance parallel with the tube along a guide rod between stops (23, 25 &c. in Fig. 2) and are then returned to their original position by return springs (22, 26 &c. in Fig. 2). Subsequently, the heated portions of the tube reach the cutting station 28 where the tube is sealed and then sheared by a shearing device 28 also moved with the tube by cams 16 or 18, the severed portions of tube passing to eccentric rollers 30 where they are off-loaded sideways (see Fig. 5, not shown), rollers 30 moving faster than the other carrier rollers, whereby the ends of the cut sections are separated immediately after cutting.

Abstract: 1,265,687. Separating hydrocarbon. BP CHEMICALS Ltd. 23 Nov.. 1970 [2 Sept., 1969], No. 43314/69. Heading B1L. [Also in Divisions C4 and C5] Gas mixtures are separated by pretreating the mixture at 100 to 450‹C by contact with a bed of molecular sieve having pore sizes in the range 6A to 15Š and then contacting the pretreated mixture with a fixed bed of 5Š molecular sieve to selectively adsorb the one constituent and then desorbing the constituent. Suitable pretreatment sieves are type X and Y sieves, e.g. a 13X type. The adsorption on the 5Š bed can be carried out isothermally at 300-450‹C and can be followed by purging with nitrogen, n-butane or n-pentane or by pressure reduction. The desorption can be effected by displacement with n-pentane or nbutane or by pressure reduction. The pretreatment sieve both adsorbs and dehydrocyclises components of the feed responsible for the decay of the 5Š sieve and is periodically regenerated by oxidative burn off. In comparative examples the pretreatment is carried out using Indian bauxite at ambient temperature or 300‹C.

The latter may be roughly elliptical in shape and disposed in staggered rows defining a sinuous course for the material in the shafts (Fig. 2). Alternatively, they may be arranged in blocks with the tubes making several passes across the shaft (Fig. 3), in which case one block may be cooled by air and another by water or oil. The final section of the grate 3 may be a sieve discharging on to a scraper chain 6 which also picks up material from the crusher 4 via shoot 5 feeding it to the elevator 7. The latter discharges on to a sieve 8, oversize material being returned to the crusher 4 by a pipe 9. The shaft may be discharged through an apertured bottom plate with another reciprocable, similarly apertured plate disposed below it, the apertures in the first plate being disposed above the solid portions of the lower plate (Fig. 2) this arrangement discharging material on to the conveyor 18. In a modification (Fig. 3) the shaft terminates in two hoppers with slots disposed over a table tiltable to discharge into a lower hopper feeding the conveyer. Another similar modification (Fig. 4) has below the discharge slots stationary tables which are swept by ploughs on endless chains.

Abstract: 1298012 Steel wire cables N V BEKAERT SA 7 Jan 1970 [22 Jan 1969] 840/70 Divided out of 3646/69 Heading D1T To reduce the relaxation value of cable composed of twisted wires of carbon steel having a pearlitic or ferritic structure, the wires are twisted together at an elevated temperature of 250‹ to 450‹C. The relaxation values may be further reduced if the wires are also subjected to back tension produced by passing each wire through a respective drawing die or through the wavy path of a wire straightener. The electrical contact between the wires and the dies or straighteners on the one hand, and the twisting head on the other hand, is exploited to heat the wires electrically before twisting. Fig. 1 shows a cabling machine the mandrel 1 of which carries wire bobbins 6 in a drum cage 5 for rotation by motor 4. The wires 7 reach twisting head 8 by way of straightening rolls 9, insulated apertures in discs 11 and 13 and insulated channels 12 which exit from the end of the mandrel. The straightening rolls are insulated from the mandrel but are connected by an insulated cable within the mandrel to a slip ring 19 for current supply from brush 18 and terminal 17, the other terminal 16 being mounted on the twist head 8. Alternatively current may be delivered by way of the guide discs 11 and 13. The mandrel bearing 3 may be constructed as an electrical generator the rotor windings of which are short circuited by the wires 7; current supply by this means increasing automatically with speed of winding. When twisted, the cable may be subjected to a final passage between straightening rollers.

In use the flanged-end 2a of the collet 2 is passed through holes 6a, 6a in the plates 6, 6, the nut 5 is tightened to move the expander member 3 and expand the end 2a of the collet 2. The latter slides until its flange 2c abut the portion 4b of the sleeve nut 4. The latter, having spanner-flats thereon, is rotated relative to the holder 1 so as to force the portion 1b thereof and the flanged-end 2a of the collet 2 towards each other. A washer 7 of leather, for example, is positioned between the portion 1b and the adjacent plate 6 to prevent the latter being damaged.

Abstract: A method for end-to end joining of paper rolls into a continuous core master is provided. The primary goal of the method is to produce usable paper roll cores from those returned for recycling after use. According to the aforementioned method, the ends of core sections are reworked into complementary shapes required for mating a joint, glue is applied to the complementary mating surfaces of the joint, the ends of the core sections are pushed in an axial direction abutting each other and the glue is set. The cross section of the cores is trued circular at least over the area of the joined core sections by applying a radial, compressive trueing force on the joint. The trueing force is also used for braking axial travel of the core sections during the joining of the core sections. An apparatus for implementing the method is also provided.
