Title: Improvements in or relating to the production of leather and of compositions for usetherein
IPC: C14C3/08
Filed: 1942-11-30
Abstract: Skins are tanned by treating them with compositions obtained by reaction of maleic anhydride and an unsaturated cycloaliphatic hydrocarbon having a six-membered cycloaliphatic ring with at least one open chain substituent on the ring and containing at least one carbon to carbon double bond which may be either in the ring or in the open chain, e.g. a cyclic terpene.  A polymerisable vinyl, vinylene, or vinylidene compound may also be present in the reaction. The compositions may contain a foam-depressant such as octanol.  The tanned skins may be treated with an aldehyde or with a salt of aluminium, iron, titanium, copper, zirconium or chromium along with acetic, tartaric or citric acids or soluble salts thereof.  The products may be used alone or in conjunction with the tanning agents described in Specifications 530,643, 542,222, [Group VIII], and 552,122, or with vegetable tanning agents, chrome tans or tanning agents containing sulphonic acid groups. Cyclic terpenes which may be used include dipentene, a -and b -pinene, camphene, a -terpinene, phelandrene, and terpinolene and other suitable compounds include vinyl cyclohexene, vinyl cyclohexane and methylene cyclohexane.  The higher molecular weight portions of the reaction products are more suitable and are obtained by extracting the lower molecular weight portions with ether.  The reaction mixture may contain 20-60 per cent of a cyclic terpene, 35-60 per cent maleic anhydride and 50-30 per cent of vinyl compound by weight.  The pH of the tanning solution is best maintained at about 4.  Examples are given of tanning agents obtained by polymerizing (1) commercial dipentene, maleic anhydride, and styrene or vinyl acetate in presence of benzoyl peroxide; (2) maleic anhydride and a -terpinene, extracting low molecular weight products with ether and mixing with a styrene-maleic anhydride polymer of Specification 542,222; (3) maleic anhydride, a -pinene and styrene in xylene; (4) vinyl cyclohexene, maleic anhydride and styrene; (5) maleic anhydride, methylene cyclohexane; (6) b -pinene and maleic anhydride with or without styrene.  Other unsaturated compounds which may be used in the reaction are vinyl phenyl ethers, methyl vinyl ketone, indene acrylic acid, methacrylic acid, methyl acrylate, methyl methacrylate, methacrylamide, acrylonitrile and methacrylonitrile.

Abstract: 1422975 Feeding, separating and texturing yarns HOECHST AG 10 April 1973 [10 April 1972] 17137/73 Heading D1F In a crimping process, two or more yarns or strands of natural or man-made materials, staple fibre or multifilamentary, are introduced individually and separately (as by use of an injector nozzle) into a crimping zone e.g. a blowing and stuffing chamber, and are maintained apart during crimping by the action of one or more fluid currents. In the apparatus shown in Figs. 1 and 2, an inlet 1 connected to a source of a gaseous medium e.g. steam or compressed air, opens into a distribution zone 2 having an adjustable annular gap 3 between a conical nozzle pin 4 and a counter core 5. Yarns fed through channels 7 and advanced into a blowing chamber 8 are kept apart (and perhaps partially assisted in their advancement) by the action of a fluid (which may be similar to or different from the fluid entering inlet 1) which connects through boring 10 with a fluid inlet 11. According to a modification, the boring 10 terminates in the zone 2 (inlet 11 then being unnecessary) so that a portion of the driving fluid is used as the separating fluid. In further embodiments of injector nozzle, channels 7 are disposed symmetrically around a central separating medium channel 9, Fig. 5, or alternately therewith in linear or circular array, Fig. 6 or Fig. 7 (not shown). The driving and separating fluid may be such as to cause permanent crimp in, or a temporary dense packing of, yarns &c in chamber 8 and may incorporate a plasticiser and/or a brightening or dyeing agent for the material of the yarns &c.

Title: An automatic printing paste feed controlling device
IPC: B41F15/40
Filed: 1956-06-04
Abstract: 787,948. Stencilling-apparatus. STORK & CO.'S APPARATENFABRIK N.V. GEB. June 4, 1956 [June 24, 1955: Feb. 15, 1956], No. 17194/56. Class 100(2) [Also in Group XXXV] Inking-apparatus. An automatic printing paste feed controlling device for use in an apparatus for screen-printing webs of cloth fabric, which apparatus includes a plurality of stencil frames each having a reciprocating squeegee in superposed relationship therewith, comprises at the end of each stencil frame corresponding with the end of the forward stroke of the squeegee a feeler which. when co-operating with the printing paste dammed up by the squeegee at said end, closes a circuit energizing a servo-mechanism that controls the feed of printing paste to the stencil frame. A feeler comprising a metal pin 8, Fig. 1, is vertically and angularly adjustably mounted on a support 9 supported on and insulated from the earthed stencil frame 5, the pin 8 contacting the electrically conducting printing paste 7 dammed up at the left end of the screen at the end of each leftward stroke of the squeegee 6, thereby earthing the feeler 8. When the feeler 8, Fig. 2, is earthed, an electrical servo-mechanism (see Group XXXV) deenergizes a relay 20 to close a contact 21 in a circuit including the secondary winding of a transformer 22 and terminals connected with the paste-feeding device, to close a valve thereof and stop the feed. When the pin 8 breaks contact with the paste, the feed in resumed. In normal operation, the alternate energizing and de-energizing of the relay 20 causes an earthed contact 26 to be connected alternately with contacts 27. 28. If the paste reservoir is empty, or the valve sticks open or closed, the contact 26 remains in contact with one of the contacts 27, 28 for an abnormal period, whereupon one of the condensers 29, 31 is discharged to extinguish the glow discharge tube 30 or 32 whereupon an electron discharge tube consisting of a triode 33 is blocked, and a relay 34 is deenergized to close a contact 35 and operate an alarm device 36. A second form of servo-mechanism is illustrated in Fig. 3 (not shown, see Group XXXV).

Title: Apparatus for generating electricity
IPC: H02J3/38
Filed: 1950-07-10
Abstract: 695,288. Generating arrangements. PETERS, J. A., BIRD, R. C., and PUTTICK, H. G. July 2, 1951 [July 10, 1950], No. 17260/50. Class 38 (iv). Relates to automatic generating plant of the kind in which a diesel engine or other primemover (not shown) of a generator G is started in response to closure of the load circuit L1, L2, through the intermediary of a control relay A which is first energized over the load circuit and contact t2 from a separate D.C. source, and subsequently held-in by the load current, the D.C. circuit to the load then being interrupted at contact t2. Interruption of the load circuit de-energizes relay A and so effects stopping of the prime-mover. The invention consists in the provision of condenser timing means in the starting and stopping circuits and of means whereby quick re-starting of the plant is effected if a load is switched on a few seconds after initiation of " stopping." In the arrangement shown, response of relay A to completion of the load circuit opens, at contacts a1, the charging circuit of a condenser C1 and connects an engine starting relay D across the condenser over contacts a2. The engine starting solenoid, controlled by contacts d of relay D, is thus energized for a period determined by the capacity of the condenser. Contacts a3 are now open and prevent energization of an engine stopping relay E. When generator G reaches voltage, a contactor T responds and connects the machine to the load circuit over contacts tp1, tp2. Contacts t1-t3 are also actuated, thereby interrupting the D.C. supply to relay A (which remains operated, however, over rectifier R by the volt-drop across a saturated choke ch), completing a charging circuit for a condenser C2, and short-circuiting condenser C1. Upon interruption of the load circuit, relay A falls out immediately, thereby closing contact a3 and energizing the " stop '' solenoid-via relay E. If the load circuit is soon re-closed, contact a3 re-opens to disable the " stop " mechanism, and the engine again drives the generator, which is still connected to the load circuit. If, however, the load circuit remains open, the engine speed continues to fall and the contactor T evenually falls out, thereby disconnecting the generator, preparing the starting circuit at contact t3 and interrupting the charging circuit of condenser C2 at contact t1. This condenser maintains the " stop " relay E energized sufficiently long to ensure that the engine speed falls so low as to prevent possibility of are-start except by actuation of the " start " relay D.

Title: Improvements in or relating to the manufacture of thermoplastic box toes
IPC: A43B23/08
Filed: 1925-07-07
Abstract: 262,838. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). July 7, 1925. Boards and compound paper; pulp, adding special substances to. - Thermoplastic box-toe blanks are produced from a sheet of material having a fibrous basis charged with thermoplastic material, the basis being a felt made irom paper pulp containing a substantial proportion of fibres of much longer length than the fibrous constituents of the rest of the pulp distributed throughout its mass. In one example, 8 parts by weight of cattle hair or other long fibres are placed in a pulp beater with 8 parts of sulphate pulp or equivalent short fibrous material and with much more water than is normally employed for beating the stock. The knives of the beating engine are adjusted so as not to cut the fibres and, after beating, the stiffening agents are added. These may comprise 35 parts by weight of resin, 25 parts of gilsonite, and 5 parts of montan wax, all finely divided and mixed with 30 parts of emulsified asphalt. Casein, in an alkaline solution, resin size, viscous animal size, or other ingredient, which when precipitated by an agent such as alum, carries down with it the stiffening materials in a more or less conglomerate mass, may also be added. After mixing, the fibrous stock is formed into a sheet of desired thickness on a cylinder paper machine, dried, and calendered. The box toe blanks are cut from the sheet and re-calendered, or the blanks may be cut from the uncalendered sheet and subsequently heated and pressed. The proportions of the stiffening agents employed may be varied, and disintegrated waste from thermoplastic box toe material may be added to the pulp. In a further example. 50 parts by weight of finely divided resin are mixed in the pulp with 15 parts of fibrous material. The resin is tempered by the addition of an aqueous soap solution. formed from oil or oleic acid, and precipating agent, which will precipitate a metallic soap, preferably a calcium soap, on the fibres in the beater and carry down the resin with it, is also added and mixed in the beater. Specifications 151,029 and 219,880 are referred to.
