IPC: D03C17/00
Filed: 1929-04-06
Abstract: 331,848. Mellor, Bromley, & Co., Ltd., Bromley, T. C., and Shortland, A. April 6, 1929. Cards and the like, punching.-In a machine for punching or perforating jacquard strips, cards, pattern discs, and the like for textile and knitting machines, a punch 1, Fig. 1, co-operating with a die 3, is reciprocated by the action of its roller 7 in a groove cam 4, which is slid on the shaft 5 into and out of operative position by means of a spring 4a, a forked lever 9, and an extension 10 connected to a treadle (not shown) by a rod 11. The disc 35, Fig. 4, to be punched is supported on a table 12 having a ratchet wheel 13, and is rotated therewith on the spindle 14 by pawls 15, 16 of a lever 17 actuated through connections 21, 22 from a shaft 20, which is rocked from the shaft 5 by the action of a cam 18 on the roll of a lever 23. The rock shaft 20 also carries a spring-controlled lever 26 with a pawl 27 for engagement with the ratchet wheel 29 of the pattern drum 19, so that the latter mav be rotated in unison with the feed movement. The disc 35 is located on the table 12 by means of a pin 36 and upstanding flanges 37 adapted to enter corresponding holes in the disc, whilst it is clamped into position by a plate 38 and screws 40. The continual rotation of the shaft 5 by hand or other means gives a rotary movement to the drum 19 and the disc 35, and a prepared pattern on the former is rotated past an adjustable pointer 30 to indicate the time for the punching action. The work feeding means applicable to punching strip material is described. The Provisional Specification describes a, reciprocating punch automatically controlled by the movement of the adjustable pointer. Specifications 267,661 and 329,369, [both in Class 74 (ii), Knitting &c.], are referred to.
Patent GB-215365-A (GB)
IPC: F02M21/10
Filed: 1924-04-30
Abstract: 215,365. Akt.-Ges. f³r Patentverwertung. May 4, 1923, [Convention date]. No Patent granted (Sealing fee not paid). Vaporiers, external; heating charge. - Specification 211,433 describes a carburetting and vaporizing apparatus for use with light and heavy fuels wherein heavy fuel from a floatchamber 17 is discharged through a nozzle 52 into a cold air passage 53 and the mixture is diluted with air from a chamber 6 which air has been heated in tubes 8 surrounded by exhaustgases. To prevent carbonization of the fuel in the mixture, the conduit 5 conveying the mixture is surrounded by a jacket 67 of cool air admitted at 56, the air being added to the mixture through perforations in the tube 54. Light fuel from a float chamber 16 is discharged through a nozzle 60 into a passage 59 leading to an air passage which, in the closed position of the throttle valve, communicates through a notch therein with the induction pipe. A notch in the opposite wall of the throttle also permits the light fuel mixture to be supplied along with the heavy fuel mixture. The invention consists in dispensing with the by-pass notches, and in making the bore 69, Fig. 3, of the throttle-valve of larger diameter than the outlet port 5<1> for the heavy fuel mixture and in displacing such bore laterally so that the walls 71, 57 are of such lengths that in the closed position of the valve the wall 71 just covers the outlet' port 72. whereas the wall 57 overlaps the port 5<1>. The result is that the valve can be adjusted to admit light fuel mixture without admitting heavy fuel, and can be adjusted during normal running to admit light fuel mixture in vitrying amounts without restricting the admission of heavy fuel mixture as in Fig. 3.

A spout 26 having a flange portion 28 and a neck portion 30 is secured to film 18 by supporting a sheet of film 18, positioning the spout 26 proximate an annularly rigidly supported portion of the film 18, forcing the neck 30 through the film 18 in the zone formed by the annular support, advancing the spout 26 through the pierced portion of the film 18 until the flange 28 contacts the film 18, and securing the flange 28 to the film 18. As shown, the film 18 is supported, preferably on a rubber cushion 16, on one end 14 of a member 10 provided with a cavity 12 in which reciprocates a ram 20 having a hollow 27 therein. The spout 16 is supported, preferably on a rubber cushion 24, on the ram 20 and enters the cavity 12 through an opening 32. A ram 15 is reciprocatably mounted in a bore 13 of a member 11 and has a cavity 17 in which a spring-loaded plunger 21 is slidably mounted. In operation, the film 18 and the spout 26 are positioned as shown. The ram 15 descends to clamp the film 18 against the member 10. The ram 20 moves upwardly to cause the neck 30 to pierce a hole in the film 18 and punch a piece (19), Fig. 2 (not shown), therefrom. The neck 30 continues its upward movement and causes the plunger 21 to ascend until the flange 28 abuts the underside of the film. An electrical impulse heating element 23, preferably comprising a thin circular ring of resistance wire insulated from the ram 15 and covered by a non-stick membrane, then heat seals the flange 28 to the film 18. The seal is cooled momentarily under continued clamping pressure. The ram 15 is elevated and the punched-out piece (19) is drawn downwardly by suction through the spout 26 and the hollow 27, Fig. 3 (not shown). In modifications (not shown), (a) the sealing element 23 is positioned in the lower ram, (b) the member 14 is not provided with the opening 32 and the spout 26 is inserted into. the cavity 12 before positioning the film 18 thereover, (c) if the neck 30 is of small diameter the spout is forced through the film 18 without detaching a scrap of film and the plunger 20 and the hollow 27 in the ram 20 are omitted, or (d) the spout 26 is attached to the film 18 by an adhesive instead of heat sealing. The spout 26 and the film 18 may be made of polyethylene or copolymers thereof, polypropylene, copolymers of ethylene and propylene, rubber or metal.

Filed: 1948-04-22
Abstract: 635,817. Sewing machines ; embroidery. GREENWOOD, F. April 22, 1948; No. 11056. [Class 112] Tufting-machines.-Fabric 2 is fed between guide members beneath reciprocating yarn-inserting members 21 adapted to pass through the backing where the yarn is engaged by trapping means 23 to form loops, each of which is subsequently engaged by a prodder or guide 27 with which co-operates cutting means for severing the loops. In the embodiment shown, the yarn 2 is fed between side guides 4 and vertically adjustable plates 5, the lower plate having teeth 7 in the rear edge, by a ratchet-driven roller 30, which may be roughened or spiked and from which the finished fabric passes to a receiving roller. A transverse row of tubular eyed needles 21, aligned with the spaces between the teeth 7, is carried by a vertically reciprocating bar 9. with adjustable stroke, and a corresponding row of oscillating loop-taking members 23 is placed beneath the fabric. A row of prodders 27, carried by a bar 26, moves to and fro to take the loops from the members 23, and may also be oscillated slightly. A separately-driven endless band knife 37 cuts the loops as they are fed along the prodders with the fabric ; the band knife may be replaced by a set of rotary cutters; on a transverse shaft, working in grooves. in the undersides of the prodders. If uncut pile is required, the cutting mechanism is stopped and the prodders withdrawn. The yarn to the needle passes round a shaft, which may be covered with friction material, arranged parallel to the needle-bar 9 and mounted in bearings sliding on the same vertical guides 8 as the needle-bar, the bar and shaft being connected by a band 14 incorporating a spring, and being kept apart by distance rods (not shown); the downward movement of the tension shaft is limited by collars on the guides 8 so that the shaft moves with the bar in the upper part of the movement of the latter but remains stationary during the lower part, thus increasing the yarn tension. The yarn preferably passes over a detector device to stop the machine in case of yarn breakage or failure. Tufting.-Single-ply yarn is preferably used each needle may carry more than one yarn. The underside of the finished material may be sprayed with an aqueous dispersion of rubber or other bonding material.

Abstract: 527,724. Delivering materials from hoppers. VERPACKUNGSBEDARF GES. April 13, 1939, No. 11259. Convention date, April 16, 1938. [Class 78 (i)] Floury or granular material, more particularly superphosphate, is delivered from a hopper spout 9 to a valve-bag filling tube 10 by a horizontal rotary disc 4 flanked by a vertical belt 8 driven by contact with the disc. The belt, which is preferably formed of rubber, restrains material which would otherwise be thrown off by centrifugal force and guides it to the tube 10. A plurality of upstanding ribs 5 on the disc engage the material and assist in delivering it, thus permitting a reduction in the speed of rotation of the disc. The ribs 5 may be replaced by a conical rotating disc, preferably of rubber, arranged to divert material from the centre of the main disc towards its periphery. In a further modification a ribbed plate is mounted above the main disc and driven independently of the latter at a regulatable speed. When the ribbed plate runs faster than the main disc and band it removes any adherent material from the latter before it leaves the periphery of the main disc. A cylindrical rotary cleaning brush may be mounted to contact with the band on its non- acting run.

The starting material may be mixed with a neutral distillate of M.W. 120-200. Up to 60% excess of the stoichiometric amount of NaOH required for neutralization may be used. Treatment may be at up to 125 C., with superatmospheric pressure used above 100 C., and the contact time may be at least 2 minutes. The volume of phase (iii) is preferably at least that of phase (i). In a preferred embodiment, phase (iii) is recycled for incorporation into the treatment solution and phase (ii) is treated as follows to recover free acids, oil and Na 2 SO 4  solution for recycling. The phase is extracted with a solvent for the oil, e.g. benzine or naphtha of b.pt. 50-250 C. The extract is stripped to recover oil and solvent. The raffinate, which contains the acid salts, is reacted with H 2 SO 4  and the product is separated to give an aqueous Na 2 SO 4  phase and a solution of the acids, which is stripped to recover solvent.

Abstract: 789,176. Drilling long holes. BISSEY, P. J. April 21, 1955 [April 23, 1954], No. 11505/55. Class 83 (3). A tube-boring machine comprises a hollow-spindle 3 to support the work 12 and a rotating tool-shaft 1 passing through the spindle. The spindle 3 is rotated by a gear 7 in a headstock 4 and carries the work 12 in a chuck 9. A belt-drive 21 rotates a cylinder 17 keyed at 20 to the shaft 1 which carries a piston 16 operated by fluid supplied by a line 24 and exhausted through passages 29, 28. The fluid is similar to cutting-fluid supplied by a line 32, so that leakage past the key 20 is unimportant. The tool is guided into the work by a bushing 36. The cutting-fluid flows through grooves in a spindle liner f, and through the work with the cuttings to a container B. The pressure of the cutting- fluid on the tool-head assists in preventing buckling of the shaft. In a modification, the tool is pulled, instead of pushed, through the work. In a further modification, the cutting- fluid entering through a line 32, Fig. 2, carries the cuttings back through the tool-shaft 43 to a cooled sump 39. The shaft is fed by a carriage 40.

Title: Recovery of formaldehyde and hydroxylated compounds
Inventor: LERER MOISE
IPC: C08L61/18
Filed: 1961-03-29
Abstract: Formaldehyde and compounds having a high hydroxyl value are produced by contacting, in an acid medium, water and heavy residues obtained in the production of metadioxanes by the condensation of formaldehyde with mono-olefines having at least 3 carbon atoms.  These heavy residues are compounds having a higher boiling point than the metadioxane product.  Preferably the ratio by weight of water used to the heavy residues is at least 0.05 and desirably between 1 and 5. The preferred value for the pH of the mixture is below 4.  Inorganic or organic acids may be used to produce the desired pH value if the heavy residues themselves are not sufficiently acidic.  The process may be carried out at temperatures up to 180 DEG C., at atmospheric or super atmospheric pressure and continuously or otherwise.  The water and the formaldehyde produced may be distilled off during or at the end of the reaction and in the latter case after optional neutralisation of the mixture.  The hydroxylated compound is left in the reaction vessel as a clear aqueous solution which is neutralised, if necessary, filtered and concentrated.
