Title: Improvements in or relating to sewing machines
Inventor: KESTELL THOMAS AUBREY
IPC: D05B57/14
Filed: 1955-11-10
Abstract: 806,265. Sewing machines. BRITISH UNITED SHOE MACHINERY CO. Ltd., KESTELL, T. A., and SNAPS, R. Nov. 8, 1956 [Nov. 10, 1955], No. 3110/55. Class 112 Lock stitching by barbed needles; shuttles. In a curved hooked needle lockstitch sewing machine having a bobbin thread case housed within a rotary shuttle arranged to pass loops of needle thread about the bobbin thread case, the shuttle has means to move a yieldable member on the thread case to cause an amount of thread to be drawn off the bobbin. The invention is described with reference to a lockstitch sewing machine similar to that disclosed in Specification 410,463. A cylindrical cup-shaped bobbin thread case 2 surrounds a bobbin 4 the thread 6 from which passes under a tension blade spring 8 through an eye 12 formed in the portion 14 of a yieldable member 16 to the outlet eye 10. The member 16 is formed of springy steel wire which encircles about 180 degrees of the thread case 2 and is attached at 18 in the case 2. The portion 14 is located in a cut away portion 20 of the case 2. Prior to the stitch forming operation, the member 16 occupies the position shown. During the stitch setting operation, the needle thread (not shown) exerts a tension on the bobbin thread 6 and the member 16 yields so that the portion 14 moves to the other end of the slot 20. After the stitch has been set, a cam 26 with a helical edge face 28, Fig. 5 which is pressed lightly into the shuttle casing 22 acts on the portion 14 of the member 16 to return the member 16 to the position shown which causes that member to withdraw from the bobbin 4 an amount of thread sufficient for the next succeeding stitch. To accentuate the bobbin thread pay-off and draw-off movements of the member 16, the cam 26 may be provided on its inner peripheral surface with an enlargement 32 which as the shuttle rotates presses against an enlargement 34 on the spring 8 and applies an additional clamping pressure to the thread. A modification in which the thread tension spring acts on the thread between the portion 14 and eye 10 is also described. This tension spring is attached to the case 2 by a keyhole shaped projection on the spring engaging a similar shaped recess in the casing.

Filed: 1920-11-16
Abstract: 153,915. Muchka, J. Oct. 30, 1916, [Convention date]. Direct air-pressure apparatus, non-automatic. -In apparatus for storing and delivering inflammable liquids using an inert gas at atmospheric pressure, the liquid is delivered from an auxiliary tank H through the pipe 1 by the pressure of the gas which is supplied through an injector 4 which at the same time draws gas from the main tank and forces it through the pipe 3 into the auxiliary tank H. When the latter is emptied to the level of the lower end of the pipe 15, at the upper end of which is a liquid seal 21, delivery of liquid ceases, and the gas supply is shut off by hand at the valve 5. The pressures in the two tanks equalize through the injector, and the non-return valve 13 permits liquid to flow into the auxiliary tank. In filling the tank, the drum is connected to the tapping place 12 and the valve 5 opened until liquid rises in the pipe 1 and forms a siphon to the drum, when the cock S is opened and the liquid siphons into the tank through the pipe 2. A vent-pipe 7 with antiflash devices 10, is provided, and an indicator J shows the contents of the storage vessel T.

Title: Unsaturated ª- diketones
IPC: C07C45/45
Filed: 1957-10-16
Abstract: Polymerized methacrylyl acetone is prepared by allowing the monomer to stand at room temperature.  The preparation of the monomer is described (see Group IV(b)).  Specification 868,107 is referred to.ALSO:Unsaturated b -diketones of the general formula <FORM:0868106/IV (b)/1> R4 wherein R1 and R2 each represent hydrogen or an alkyl radical, R3 represents hydrogen, halogen or an alkyl radical, R4 represents hydrogen or an alkyl group containing up to 3 carbon atoms and n is zero or 1-5, are prepared by reacting an ester of an unsaturated carboxylic acid of the general formula CR1R2 =CR3-(CH2)n COOH with a methyl ketone CH3COCH2R4 in a Claisen condensation with cooling.  It is stated that the product may contain some b -diketone CR1R2=CR3-(CH2)n CO-CHR4COCH3. The diketone methacrylyl acetone is claimed as a new compound. The condensation is effected in the presence of an alkali metal or alcoholate or amide thereof preferably using an ester of for example acrylic, a -substituted acrylic or b -substituted vinyl acetic acid, which has been stabilised with a basic polymerisation inhibitor, in the presence of an inert solvent at about 0 DEG C.  The b -diketone is preferably isolated in the form of an aqueous solution of its alkali metal salt which is then acidified to liberate the free diketone.  It may be purified by treating with an aqueous solution of ferric ions, e.g. aqueous ferric chloride, separating the resulting aqueous solution of the ferric complex of the diketone, acidifying to decompose the complex and extracting the diketone with a solvent e.g. chloroform.  After removal of solvent, the pure monomeric diketone may be separated by fractional crystallisation or distillation from minor amounts of polymer.  An example describes the preparation of methacrylyl acetone from acetone and ethyl methacrylate.  The use of some of the diketones in the manufacture of ion-exchange resins forms the subject-matter of Specification 868,107.

Title: Improvements in or relating to the manufacture of regenerated cellulose structures by the viscose process
IPC: D01D5/22
Filed: 1956-10-26
Abstract: Regenerated cellulose structures, e.g. fibres and filaments, of high tenacity, are made by extruding viscose into an aqueous bath containing up to 10% by weight of sulphuric acid, at least 13% by weight of sodium sulphate, and at least 5% by weight of zinc sulphate, with stretching of the extruded structures, in the presence of less than 0.5 millimol. per 100 grams of viscose or spinning bath of a water-soluble quaternary ammonium compound, the viscose being prepared by xanthating alkali cellulose with at least 37 per cent by weight of carbon disulphide, based on the cellulose content of the alkali cellulose, and the percentage by weight of carbon disulphide used being at least 4.9 times the percentage by weight of sulphuric acid in the bath. Water-soluble, non-surface-active compounds of the formula R1R2R3R4N-X, where R1, R2, R3 and R4 are organic groups having not more than four aliphatic carbon atoms, at least three of the groups containing only aliphatic carbon atoms, and the fourth group, when aromatic, containing no more than one benzene nucleus, and X is an hydroxyl group or an anion having substantially no surface activity, e.g. the chloride, bromide, iodide, sulphate, bisulphate or acetate anion, are preferably used.  Specified compounds are benzyltrimethyl ammonium chloride, tetraethyl ammonium hydroxide, phenyl trimethyl ammonium hydroxide, tetraethanolammonium hydroxide, tetraethylammonium bromide, tetramethylammonium iodide, tetrapropylammonium hydroxide, tetrabutylammonium chloride, tributylpropylammonium hydroxide, tri-(beta-hydroxyethyl) - methylammonium hydroxide and tributyl - (beta - hydroxyethyl) - ammonium iodide.  The viscose used, which may be ripened or unripened, may be obtained by xanthation performed in the conventional manner or by a split xanthation p  procedure.  It may be extruded hot or cold, but is preferably heated to 40-80 DEG  C.  The spinning bath is also preferably heated to 40-80 DEG  C. and may contain, in addition to zinc sulphate, other divalent metal salts, e.g. ferrous sulphate, manganese sulphate, nickel sulphate or chromic sulphate.  After extrusion, the filaments may travel through about 25 to 150 inches in the primary bath, where they may be confined to a small area by means of multiple rollers, designed to apply tension to the travelling filaments in gradual increments and thereby orient them while still plastic.  Part of the stretch is preferably applied, however, beyond the primary bath by-passing the filaments through a secondary bath or shower located between two feed-wheels.  The secondary bath may consist of water, dilute (1-4%) sulphuric acid or diluted spinning bath at a temperature between 50 DEG  and 100 DEG C. Total stretches of 80% or more are preferably used for producing high-tenacity yarns.  The quaternary ammonium compound may be added to the viscose during dissolution of the cellulose xanthate. Specifications 652,741, 712,623 and U.S.A. Specification 2,801,998 are referred to.

Abstract: 940,801. Change-speed and clutch control. TWIN DISC CLUTCH CO. Sept. 23, 1960, No. 32812/60. Headings F2D and F2L. In a hydromechanical vehicle transmission variation of the torque converter slip is used to indicate when gear changing is required or to effect such gear changing automatically. In the arrangement shown high and low speed ratio governors 14, 15 are driven by the converter input and output shafts 16, 17 and effect automatic control of the hydraulic clutches 109, 110 of a two-speed gear. The high speed governor 14 comprises two aligned shafts 26, 34, the former of which is in two portions connected by a magnetic clutch 23, 25. The shafts 26, 34 are connected to the converter shafts 16, 17 by belts 18, 19, and the gear ratios are such that the shafts rotate in synchronism at a predetermined low value of converter slip. The shafts carry lugs 29, 37 on which are mounted electric contacts 30, 38 wired to slip rings and brushes 32, 40 and 33, 41 whereby in the event of shaft 26 slowing down in relation to shaft 34 the contacts engage to operate relay contacts 72, 73 to energize a solenoid valve 94 and admit pressure liquid to the high gear clutch 109. The governor 15 is similar to governor 14 except that it operates at high slip and the arrangement of contacts 50, 57 is reversed so that they engage when shaft 43 speeds up in relation to shaft 44, to operate relay contacts 79, 80, solenoid valve 95 and the low gear clutch 110. Instead of operating valve relays the electric contacts may illuminate signal lamps to warn the driver when gear change is required, Fig. 7 (not shown). In a further arrangement, Figs. 8-11 (not shown), the slip rings and contacts are duplicated to operate a four-speed gear.

Abstract: 480,901. Rolling flanged and profiled bars. BARTSCHERER, F. Nov. 30, 1936, No. 32820. Convention date, Feb. 27. [Class 83 (iv)] In producing rolled articles such as rails and profiled bars with the crystallites at particular parts of the section disposed parallel to the surface, the ingot is heavily deformed at those parts, e.g. from 50 to 80 per cent in a single pass. The deformation is preferably effected by providing reinforcements b, on two opposite faces of the ingot a, which are to form the head and foot of a rail, and rolling down these reinforcements into the hatched portions of the surface. Alternatively the rolls may be shaped so that accumulations of metal b are formed in a rectangular ingot in an intermediate pass and are subsequently rolled into the surface. The reinforcements preferably disappear at the ends of an ingot to facilitate its entry between the rolls, and the stages in the production of a rail section are shown in the Specification.
Patent GB-328602-A (GB)
Abstract: 328,602. Tollemache, H. D. Jan. 30, 1929. Totalizators.-In arrangements involving a distributing switch controlling a group of ticketissuing machines, loss of a count is prevented by ensuring maintenance of the counting circuit for a predetermined period after opening of the circuit for operating the machine. As shown applied to two issuing-machines with a common distributing switch K, each machine is provided with two operating switches A, B for win and place bets respectively and with a horse-selecting switch H, the settable arm of which carries six contacts linked up and co-operating with segments and rings as shown. The outermost segments are wired to counting-elements N' for win bets, and the next ring of segments to similar elements M<6> for place bets. The third series of segments is wired to separate switches H<3> to permit cutting-out of unwanted circuits. The horse-selecting switch arm having been set, the operator depresses the operating switch, for example A, until the distributing switch completes circuit for the machine in question whereupon the relay switch C closes two circuits by means of its contact arm C<1>. One circuit is through the motor L<3> so that the machine operates to issue a ticket and by means of a cam L<5> maintains the arm in operative position until the end of the cycle. The other circuit, closed at L and extending to the distant counting- apparatus, is through a second series of contacts O on the distributing switch and these are angularly echeloned with respect to the operating circuit contacts K<1> to ensure the counting circuit remaining complete for a short while after the arm K<2> has opened the operating-circuit. The extent of the echeloning may be adjustable. Specifications 328,700 and (in the Provisional Specification) 328,594 are referred to.
