Title: A method and device for packaging bundles of fibre strands
IPC: B65B1/24
Filed: 1961-09-04
Abstract: 940,580. Packaging-machines. ATELIERS SAINT ELOI. Sept. 4, 1961 [Sept. 9, 1960], No. 31732/61. Heading B8C. Fibre strands are packaged in a container of thermo-weldable material, formed of an upper member 11 and a base 10, by means of a can 1 and upper and lower pistons 7, 6 respectively, the base 10 being welded to the upper member 11 by movable jaws 12, 13. After the base 10 has been placed in position on a movable member 3 forming a base for the can 1, the can 1 is filled with fibre strands, clamped on a table 4 by a member 5 and the member 11 fitted over the top of the can. The piston 7, to which a plate 8 is secured, is lowered to the position shown in Fig. 1. The piston 6 is raised to compress the fibre and finally overcomes the downward pressure of the piston 7, thereby raising the partially formed package clear of the can 1 for welding of the base 10. In a modification the jaws 12, 13 are replaced by sectors, the package being rotated between successive welds.

Title: Improvements in the method of and means for the extraction of oils and the like from bodies containing the same
IPC: C11B1/10
Filed: 1926-12-14
Abstract: 288,670. Simon, L. J., and Simon Extracting Machine Syndicate, Ltd. Dec. 14, 1926. Fats and fatty oils, extracting by solvents. - In the extraction of oils, fats, waxes, and the like by subjecting the raw material in a basket rotating in a closed extractor to successive flushings with progressively purer solvent as described in Specification 255,923, the flushing with each grade of solvent is repeated before that with the next purer grade by continuously withdrawing the solvent from the extractor and reintroducing it to the centre of the basket. Using the apparatus shown, the material in an extractor 15 is first treated with solvent supplied under its own pressure from an evaporator 22 by pipes 20, 17, and 14; thrice-used solvent is then withdrawn from the compartment 6 of the solvent tank 1 through a valve into a heater 10 common to the compartments 3 - - 6, and is passed by a pipe 11 to a pump 12 which forces it to the extractor through pipes 13, 14; it is withdrawn to the heater through a valve and a pipe 50, and circulated for the desired time. This solvent then flows from the extractor through a valve to a header 9 at the top of the tank 1, and passes to the next compartment 7. The material is similarly washed with twice-used and once-used solvent from the compartments 5, 4, respectively and finally flushed with fresh solvent from the compartment 3 fitted with a float valve 8 to determine the charge for each flush. The material is again treated with solvent vapour, and finally with steam supplied through a separator 19, valve 18, and pipes 17, 14. The fully-used solvent is withdrawn from the compartment 7 through a pipe 25 and a valve. 26, and forced by a pump 24 through a pipe 23 to the evaporator 22; it is afterwards passed through a valve 47 and a pump 43 to a still for the recovery of the oil &c. extracted. As in Specification 255,923 the appropriate valves are automatically opened and closed in predetermined and timed sequence by a master cam-shaft. Subsidiary cam shafts 27, 28 operated thereby are provided within the headers 9, 10.

Abstract: 1345437 Dumper vehicles; vehicle exhaust systems EUCLID Inc 8 July 1971 [13 Aug 1970] 32225/71 Headings B7B and B7H The dump body 15 of an off-the-road dump truck is heated, to prevent freezing of the contents, by the exhaust gases from the engine through a frame 11, a duct 33 and a coupling 34 enabling the duct 33 to move relatively to an exhaust duct 31 as the body 15 moves. The body 15, Fig. 3, has members 17b, 17c, 17d and 17e defining a passageway 20 for the flow of exhaust gas in the direction of arrows for heating the body before expulsion to the atmosphere. The body 15 is pivotally connected at 21 to the frame 11 between loading and dumping positions Figs. 1 and 2. The ends 35, 37 of the ducts 31, 33 respectively enable the relative movement of ducts during movement of the body 15. A tubular body 40 integral with duct 33 defines an opening 41 through which duct 31 extends and has flat side walls 42, 44 and arcuately curved walls 46, 48. A duct 31 carries a sealing flange 50 extending around the duct engaging a flange 52 carried by the member 40, to prevent the escape of gases. When the body 15 is moved to dumping position the member 40 rotates about axis 26, thereby disengaging flanges 50, 52 and engaging a flange 54 with flange 52 to provide, with the aid of gaskets, not shown, a tight seal. Duct 33 has branches 56, 58 provided with a vane 62 which by rotation of a rod 64 controls the flow of gases to the passageway 20.

[Also in Division F2] A method of producing helically grooved flexible tubing comprises helically winding a longitudinally corrugated metal strip S, having flanges 10 and 12 projecting in opposite directions, on to a rotating mandrel 2 so that the flanges overlap one another, folding over the overlapping flanges to form a continuous seamed joint, and bending over a corrugation 70 adjacent the seamed joint so that it engages over and locks the seamed joint in position. The strip, corrugated by rolls 14, is fed against the face 8 of a guide ring 6 so that the flange 10 is held between a joint blade 68 and the face 8. The strip is then fed by the rotating mandrel 2 under a former block 15 which comprises former plates 16 and 17, Fig. 4, a plurality of guide plates 18 with spacer plates 19 interposed between them, and a single guide plate 20 having corrugations 21. The forming plates 16 and 17, coact with one another so that the corrugation 13 is bent towards the flange 10 while the flange 12 is bent towards the flange 10, Fig. 10, after which the overlapping flanges are bent over so that they lie parallel to the axis of the mandrel, Fig. 12. The joint is then partially flattened by a driven, knurled roller 31 and is finally flattened by a driven pressure roller 33. Clinch rollers 57 and 57a finally bend the corrugations 70 over the flattened seam.

[Class 7 (vi)] Piston-controlled exhaust ports are fitted with a freely-mounted axially movable annular valve adapted to open and close under the control of the pressure of the exhaust gases. In the form shown in Fig. 1, exhaust ports 3 are closed by a ring valve 5 extending around, and moving axially of, the cylinder, the valve being closed by fluid pressure contained in a bellows 7 connected by a pipe 8 to a chamber 9 with a screwed plug 10 for adjusting the pressure. The passage 4 leading from the ports 3 is inclined at 4a so that when the ports are uncovered by the piston, the exhaust gases have access to the end of the valve 5 and open it, escaping in a sudden puff, the valve then reclosing quickly and preventing back-flow of exhaust into the cylinder. In a modification, the valve is in the form of a flexible ring 11, Fig. 3, secured at its inner edge between a flange 14 and projections 13 arranged between the ports 3, the seating 12 of the valve being curved as shown. A groove 16 in the seating may form an oil seal. The ring valve 11 may be laminated.
