Title: Improvements in and relating to the manufacture, production and treatment of artificial thread and the like, and in apparatus therefor
IPC: D01D10/04
Filed: 1930-11-01
Abstract: For the washing, desulphurizing, bleaching, soaping, &c. of artificial silk &c. the cakes or bobbins <PICT:0363064/IV/1> <PICT:0363064/IV/2> are supported between two endless flexible bands by means of which they are conveyed to a source of liquid or gas under pressure, the arrangement being such that liquid or gas is supplied to the interior of the cakes or bobbins.  Thus, there may be employed an upper belt B and a lower belt A driven at the same peripheral speed and the upper belt arranged to converge on the lower belt in order to permit the cakes C preferably arranged in tiers to be placed in position, while at the other end of its travel the upper belt follows an inclined path to enable the cakes to be removed after treatment.  Rubber rings F, G secured to the outer faces of the bands locate the cakes in position.  The lower band moves across the face of a chest I to which liquid under pressure is supplied from an upper tank L, the face of the chest being provided with slots K which register with holes H in the centre of the rings F, liquid thereby passing to the interior of the tier of cakes and after flowing through the cakes is collected in a trough M from which it is returned to the tank L; the tiers of cakes are held in position and their upper ends sealed by means of a pressure-plate P over which the upper band B travels.  The apparatus may be arranged for the treatment of the cakes with different liquids in succession, in which case a series of chests I across which the band A travels, are provided; and in order to remove the liquid carried by the cakes after treatment, the upper band may be arranged to move across the slotted face of a chest supplied with compressed air, access of which to the interior of the cakes is permitted by providing perforations in the centre of the rings G similar to the perforations in the lower band.  The cakes are preferably each supported on a resilient holder D, for example, as described in Specification 362,114 and of a length sufficient to permit a limited expansion of the cakes; distance-pieces E of annular construction press against the intermediate ends of the holds so that a watertight joint is made.

Title: Fluid seal
IPC: F01D11/02
Filed: 1959-09-29
Abstract: 859,525. Stuffing-box substitutes; turbines; axial-flow and radial-flow compressors. ROSE, A. A. S. Sept. 29, 1959 [Oct. 9, 1958], No. 33047/59. Classes 110 (1), 110 (3) and 122 (5). A seal between a hollow member 42 and a rotary member 17 within the hollow member comprises an annular abutment 44 on the first member, a second abutment 45 on the second member, a plurality of plates 27 in contact with the second abutment and elastic means 37 mounting the plates on the second member such that in one position of the plates a gap is maintained between the outer peripheral edges 30 of the plates and the abutment 44 and in a second position determined by the speed of rotation of the second member, the edges are in sealing relation with the latter abutment. The rotary member 17 is shown as one of the discs of the rotor of the compressor of a gas turbine, and the member 42 is a sealing-ring on the engine spline 26. The plates 27, which may be of stainless steel, are arranged with a small gap between their ends so as to form a complete ring and are connected by the elastic means, in the form of leaf-springs 37, to a similar inner ring comprising plates 32, the leaf-springs being welded to both sets of plates. The plates 32 are clamped, as shown in Fig. 2, to the rotor 17 of the gas turbine compressor between an annular plate 41 and the rotor by bolts 40, the outer surface of the plate forming the second abutment surface 41 against which the plates 32 are urged by the gas pressure. On initial assembly of the seal to the rotor, a gap is provided between the edges 30 of the plates 27 and the abutment surface 44 but when the compressor is run up to maximum speed, the plates move outwardly under the action of centrifugal force into sealing contact with the surface 44. In order to overcome the effects of manufacturing tolerances, the springs 37 are of such strength that on the first run up to maximum speed of the compressor they allow the plates 27 to be forced outwardly so that the edges 30 wear away by the engagement thereof with the abutment 44 until a dimension is attained, such that on subsequent operations, the edges maintain the desired sealing contact; during this initial operation, the springs may be extended beyond their elastic limits. The end of the plates 27 may be arranged to overlap in order to seal the gap therebetween (Fig. 11, not shown) and, if desired, the ends may be tongued and grooved. The invention is applicable to turbines and radial flow compressors.

Title: Improvements in or relating to the manufacture of ª‡-substituted formylaminomalonic esters and ª‡-amino carboxylic acids derived therefrom
IPC: C07C227/14
Filed: 1946-11-13
Abstract: a -Substituted formylaminomalonic esters of the formula <FORM:0621706/IV (b)/1> where R1 is hydrogen, alkyl, alkenyl, phenyl, an alkyl group containing an ether, carbalkoxy or thioether group as substituent or an aryl group having an ether group as substituent, and COOR11, COOR111 denote esterified carboxyl radicals, are manufactured by condensing a formylaminomalonic ester in the presence of an alkaline condensing agent with an organic halide of the formula R1CN2X.  The products on heating with aqueous sulphuric, hydrochloric or phosphoric acid are hydrolyzed and decarboxylated to give a -amino acids or by reacting with two molecular equivalents of alkaline hydrolysing agent followed by heating in aqueous solution at a pH of 5-7 yield N-formyl amino acids.  The latter may be used for resolution into the optical isomers, which are then deformylated. The organic halide is preferably a chloride or bromide, examples being <FORM:0621706/IV (b)/2> <FORM:0621706/IV (b)/3> <FORM:0621706/IV (b)/4> <FORM:0621706/IV (b)/5> which yield the substituted esters convertibl respectively into nor-leucine, leucine, phenylalanine, aspartic acid, glutamic acid, tyrosene, and methionine.  In examples: (1) sodium is dissolved in ethanol, ethyl formylaminomalonate added, followed by benzyl chloride, with heating under reflux, sodium chloride and ethanol then being removed, and ethyl a -formylamino-a -carbethoxy-b -phenylpropionate recovered. Heating with aqueous sulphuric acid converts this to dl-phenylalanine; (2) sodium alcoholate is slowly added to ethyl formylaminomalonate and n-butyl bromide in alcohol, ethyl a -formylamino-a -carbethoxy-n-caproate being recovered; refluxing with aqueous hydrochloric acid gives nor-leucine; (3) ethyl chloroacetate similarly reacts to yield a product which is hydrolysed to aspartic acid; (4) the condensation product of (1) is boiled with aqueous sodium hydroxide, the solution made just acid to bromthymol blue, and heated while maintaining acidity, dl-N-formylphenylalanine being recovered.  Specification 618,591 is referred to.

Title: Improvements relating to the manufacture of bags
IPC: B31B19/90
Filed: 1961-09-21
Abstract: 981,292. Making draw-string bags. D. E. ARNOLD. Dec. 21, 1962 [Sept. 21, 1961; July 18, 1962], Nos. 33762/61 and 27518/62. Heading B5D. [Also in Division B8] A rectangular bag formed by folding at 22 (Fig. 1) a length of material, and stitching it at 23, 24, and which is closed by a drawstring 27 held in a hem 26, is produced in a machine in which the blank of material is conveyed successively in two directions at right angles. In the machine shown in Figs. 3 and 4, material from a roll 46 (Fig. 4) has a hem turned over by a folder 29 and is then cut by a guillotine 49 into lengths which are fed by belts 52 under idler rollers 82 so that the hem can be opened by air jets 98 to permit a draw-string to be fed in. The draw-string is fed through a tube 102 (Fig. 6) adjacent a plate 100 holding the hem open. The draw string is pulled from a roll (not shown) by claws 111 (Fig. 8) which draw the draw-string downwardly against a rotating cutter-wheel 108. During this action the end of the draw-string which has passed the cutter wheel 108 is held by a roller 89 (Fig. 3). The movement of the claw is controlled by a feeler 117 detecting the presence of a bag. The hem 26 (Fig. 1) is then sewn over the draw-string by a machine 35 beneath which the blank is carried by powered rollers 86 sliding the blank over a fixed base. The cottons joining adjacent blanks are then severed by a cutter provided with an air jet which blows the severed ends of the draw strings clear. A further belt conveyer then moves the blank beneath a folding bar 141 which, when the leading edge of the blank registers beneath a photo-electric cell 145, pushes the blank through a slot 148 in a baseplate so that it is carried by rollers 149 (Fig. 11) along a curved base-plate 161. After being thus folded the bag is advanced beneath a sewing head 40 which provides the stitching 24 (Fig. 1) which may incorporate a label 25 laid on the blank by a feed 162. When the blank subsequently registers beneath a photo-electric cell 165 driven rollers 171 are lowered on to it to drive it past a further sewing head 42 which provides the line of stitching 23 (Fig. 1). Further devices 41, 42 are provided for cutting the cottons applied by the machines 40, 42. According to the first Provisional Specification the three lines of stitching 26, 23, 24 are applied on successive lengths of the machine with the direction of motion of the blank changed through a right-angle between each section. This subject-matter does not appear in the Complete Specification.

Abstract: 1,083,095. Testing I.C. Ignition circuits, W. S. FORTUNE. Aug. 9, 1965, No.34064/65. Heading G1U. A system for testing the ignition circuitry 10-19 of an I.C. engine includes a set of ignition signal monitoring lamps 24 each coupled to a terminal of one of the spark plugs 19 through current limiting resistors 30, and an adjustable external spark gap 38 in series with a current limiting resistor 48 and a spark monitoring lamp 50, arranged to be coupled in parallel with a selected spark plug sparking gap. The monitoring lamps are arranged on a display panel 22. A switching arrangement 32, is operated from the control panel by a momentary contact switch 60 which permits the energization of a solenoid 62 to operate a ratchet drive 56 and connects the adjustable gap 38 in parallel successively with each sparking plug. A further coupled switch 52 connects the related indicator lamp to earth, so that the particular plug is identified. Instead of the momentary contact switch 60, a manual control 67 may be used to adjust the switch 32. In carrying out a test, the steady glow of the lamps 24 indicates that there is no break in the leads or short to earth of the spark plug H.T. Each plug is then tested to determine whether the gap is correct by connecting the adjustable gap 38 across it and adjusting the gap until the related plug ceases to operate. The plug gap setting must then be slightly greater than the setting of the adjustable gap, the operation of which is indicated by the neons 50 and 50'. If the adjustable gap is larger than normal, an eroded electrode on the selected spark plug is indicated, while if the gap is shorter than normal, the plug is faulty.
