Title: An improvement in or relating to machines for cutting the pile of pile fabrics
IPC: D03D39/24
Filed: 1930-06-18
Abstract: 352,689. Cutting pile of pile fabrics. CARMICHAEL, E., Highfield, Cross Lane, Latchford, Warrington, Lancashire, and UNITED VELVET CUTTERS ASSOCIATION, Ltd., Cable Mills, Glasshouse Street, Oldham Road, Manchester. June 18, 1930, No. 18567. [Class 42 (i).] Stop-motions.-In a weft-pile cutting machine in which the knife d is pivotally mounted on an arm a which is itself pivoted on a tube or rod b, an armature i, carried directly by the arm a, is adapted to be attracted by an electromagnet j so long as cutting proceeds normally, and to be released, upon any abnormality in the cutting, to permit the knife arm to be swung out of cutting position by the usual spring r. The magnet circuit is maintained unbroken by the contact of a plate h with a blade f<2> mounted on an intermediate knife-supporting lever f, but, when the pressure on the knife is increased or diminished, the contact f<2> is caused by the action of the spring; g to move clear of the contact h and break the circuit. Stoppage of the machine, on movement of the knife arm out of cutting position, is conveniently effected by connecting a lead j<1> from the magnet to a magnet circuit controlling stop mechanism in which circuit the plate h is included, whilst the usual stop motion, operative at the end of each race, may also be included in the circuit so as to raise the knife to inoperative position when the end of a race is reached. Specification 311,555, [Class 42 (i), Fabrics, Finishing &c.], is referred to in tie Provisional Specification.

Abstract: 675,908. Gas-producers; coke ovens. KOPPERS GES., H. July 27, 1950 [Dec. 9, 1949], No. 18794/50. Classes 51 (ii) and 55 (i). The air supply to a producer 19 providing gas for a regeneratively-operated oven 1 is regulated by a valve 22 in dependence on the pressure in the supply line 18 to the oven through the medium of a governor 24 and in addition electromagnetically operated means actuate the valve through the governor by means of a switch operated from the reversing machine 14 controlling the valves of the regenerative heating system. The valve is opened thereby just before the gas supply is removed after each of the intervals between the cutting-off to one and supply to the other set of regenerators, the partial vacuum then prevailing in the gas conduits being thus prevented from extending into the producer. As shown, tappets 34 on a cam disc 33 on the reversing machine engage a contact element 32 in a circuit including the winding of an electromagnet 30, which acts either on the governor diaphragm 26 or on a needle valve controlling the application of hydraulic pressure to the underside of a piston 29 with which the air valve 22 is linked.

Title: High pressure closure
IPC: F22G3/00
Filed: 1956-06-21
Abstract: 794,551. Closures for resisting fluid pressure. BABCOCK & WILCOX CO. June 21, 1956. [July 6, 1955], No. 19297/56. Class 123(1) The closure 18 for a pressure vessel 10 has a grooved flange 20 seating on a gasket disposed on a correspondingly grooved flange 14 around the vessel rim, the flanges 20, 14 being formed externally with respective inclined portions 22, 24, to receive C-shaped clamps 26 arranged adjacent to each other and completely surrounding the periphery of the vessel. Each clamp has inclined surfaces 28, 30 respectively matching the flange portions 22, 24 so that application of a radially inward force on the clamps results in a compressing reaction on the sealing gasket. The radial force is applied simultaneously to all the clamps by a ring 36 having internal inclined surfaces 32A, 34A which engage outer inclined surfaces 32, 34 on the clamps when the ring is forced upwardly, the ring being driven by a number of jackscrews 42 mounted on brackets 44 disposed at spaced positions around the vessel 10. The screw members 48 of the jackscrews are driven upwards together by internally threaded pinions 52 which are rotated simultaneously by a toothed ring 54, the latter being driven around by a shaft 62 carrying a pinion 64 engaging teeth cut on the underside of the ring. To release the clamps from engagement with the flanges 14, 20 the clamps are supported on a pivot ring 38 and provided with lower external projections 40 which are engaged by the bottom edge of the ring 36 during its downward travel, this causing the clamps to pivot outwardly to allow the closure 18 to be removed. The unit is readily capable of operation from a remote position since the driving force to seal or. unseal the vessel is applied at a single point only.

Abstract: 491,555. Book - keeping appliances ; copying documents ; addressing &c. machines. RANDZIO, R. July 12, 1937, No. 19327. Convention date, July 14, 1936. [Class 16] [Also in Group XVI] A manifolding-pad for use in a book-keeping system comprises record sheets 1, Fig. 1, with interposed carbon sheets, all the record sheets except the top one being separable into narrow transverse strips, and all the sheets being separably secured together at one common margin 3, the top and bottom record sheets being extended at 6 and secured together, and the intermediate record sheets differing in width, the width determining whether the strips of these sheets are to be used subsequently for either debit or credit entries. The bottom edges of the top and bottom record sheets may also be extended at 6<1> and secured together. Entries are made on the pad preferably by a typewriter, and for that purpose the paper-holder of the typewriter has a strip fitted thereto to act as a guide to indicate matter to be typed in the various columns 8 of the pad. The pad is then divided by tearing off the top and bottom portions 6, 6<1>, removing the intermediate record sheets from the border 3 along perforations 5, and then tearing off the transverse strips of the latter sheets along perforations or cuts provided in these sheets. The transverse strips may then be either gummed to account cards by the use of an adhesive which has to be heated, or the entries thereon transferred by moisture to the account cards. When the strips are to be gummed to account cards, the record sheets of the pad are preferably transparent, and the carbon sheets are arranged to give a " mirror " copy of the entries on the back of each record sheet, so that the actual entries are protected when the strips are gummed to the account cards. A machine for gumming the strips to the account cards is shown in Fig. 7, and comprises a casing 16 in which a slide 17 is mounted, the slide having rack teeth 21 at each side engaged by pinions 20 on a shaft rotatable by means of a hand wheel 18. Ratchet-means to ensure even step-by-step movement of the slide 17, and automatic return means therefor may be provided. Several devices comprising inclined surfaces 22 and spring clips 23 are detachably mounted at 25 on the machine with their free ends resting on the slide 17. The entry strips 1<1> are sorted and arranged on the devices 22, 23, and the account card 11 is placed on the slide 17. Either the account card or the strips may have adhesive thereon. The strips are fed by hand or by manually-operable endless bands on to the account card, and each strip is gummed to the card by moving a hand-crank 32 partly to rotate a shaft 30 on which an electrically-heated head 29 is secured, the head swinging down into contact with each strip as it is fed into position. The head 29 is provided with a moistening member where the entries are to be transferred from the strips 1<1> to the card.
