Title: Method and apparatus for the production and/or processing of a sheet of material by compression
IPC: B29C43/12
Filed: 1971-05-27
Abstract: 1354615 Laminating press and method KALLE AG 27 May 1971 [29 May 1970] 17530/71 Headings B5N and B5F [Also in Division B6] A method for the production of a laminate or an embossed sheet of material by compression, comprises in a first step, applying a constant pressure to the centre of the starting material and then progressively extending the area to which the constant pressure is applied toward the edges of the material, this pressure being sufficient to remove air from between adjacent surfaces of material for laminating or from the surface of the material to be embossed but insufficient to laminate or emboss, then in a second step increasing the pressure until the full compression pressure is applied to produce the required product. The second step of the method is preferably effected at an elevated temperature. An apparatus for use in the method includes a die plate 2 and a base-plate 9 adapted to support the material being processed by pressure applied by the die plate, the die plate having an aperture 5 therein, and, positioned adjacent to its pressure surface a sheet 3 of flexible, elastic, pressure-resistant, impermeable material, e.g. natural rubber, butadienestyrene rubber, butadiene-acrylonitrile rubber, butyl rubber, polyacrylic rubber, chlorosulphonated polyethylene or silicone rubber, such that while the die plate and the base-plate are separated, the sheet can be inflated by fluid pressure exerted between the die plate and the sheet through the aperture, whereby the sheet becomes distended from a position in which it is in contact with the die plate, means being provided whereby on compression of the inflated sheet between the die plate and the base-plate, the said fluid can be expelled at substantially constant pressure. In the embodiment shown, the base-plate 9 is heatable and has a profiled surface 10, air under pressure is introduced through the pipe-line 6 and peripheral channel 7, and constant pressure is maintained by the valve regulator 8, a piston 1 serving to lower the die plate. The material to be laminated or embossed comprises one or more cut sheets of material, each cut sheet consisting either of a single layer of material or of several united layers of different materials. Specified materials for single layer cut sheets are homo- and copolymers of vinyl chloride, polyolefine, butadiene-acrylonitrile copolymer or polyurethane. Specified two layer cut sheets consist of a matted fleece of polyester fibres and a polymer layer, e.g. of one of the polymers specified above. Preferred multi-layer cut sheets comprise either an outer layer of microporous polyurethane or a stretched polyester film bonded to a physically homogeneous layer of polyurethane.

Abstract: 1,143,342. Sewing machines. PRESTON ENGS. (PRECISION) Ltd. 7 July, 1967 [22 April, 1966], No. 17616/66. Heading D1G. A looper assembly when assembled in a conventional looper bar in a tufting machine is characterised in that a looper thereof is positioned at such an angle relative to the looper bar as to be capable of presenting the centre of a loop to a relatively moving cutting knife. As shown, a standard looper 18 carried by a looper block, is bent at B through an angle of about 20 degrees, and the co-operating knife blade 20 is similarly inclined, whereby the limb 21a of the seized yarn loop extending from its upper end Y to the point Z of severing is increased so as to be substantially equal to the other limb 21b from its upper point X to point Z.

Title: Improvements in methods of and apparatus for making seamless tubes

Filed: 1929-06-08
Abstract: 314,523. Babcock &. Wilcox Tube Co., (Assignees of Inslee, H. C.). June 30, 1928, [Convention date]. Rolling tubes; skew-rolling.-In the manufacture of seamless metal tubes by cross rolling and compressing a heated round billet so as to advance the metal over a piercing mandrel the relative speed of the, rolls is adjusted to reduce any difference, in work being done by the rolls. The conical rolls 10. 11 are carried by shafts 15 supported at an angle of about 30‹ to the centre line of the machine and skewed at about 6‹, and the two rolls are driven by separate motors 25, 26. Any difference in work done by the two rolls due to different degrees of smoothness of the rolls would result in unequal pressure of the billet 14 against the guides 12; this is avoided by providing a load indicator and speed controlling means for each motor. Automatic control may be secured by employing compound wound direct current motors having a limited but substantial drooping speed-torque characteristic, whereas shunt wound motors are employed if manual control of the speed of the rolls is depended on alone. The, roll shaft supports 17 are adjustable about the pivots 28 by screws 35 and secured in position by clamp bolts 30, 32.

Water or like liquid is supplied to a unit 11 at 31 and flows, under the control of a manually operated valve 18, through passages 30, 14 and 13 to an outlet 15. The liquid flow draws disinfectant or the like from a container 35 through a tube 34 and a passage 33 to the passage 13. The mixture leaves the outlet 15 and strikes a deflector 41 to create a spray. A needle valve 39 in the passage 33 controls the flow of disinfectant, &c. The valve 18 is normally urged by a spring 24 into a closed position, and is opened by a pivoted lever 27. The Provisional Specification states that an aperture, preferably provided with an adjustable screw valve, may be arranged in a part 32, to enable air to be sucked in at the same time as the liquid is drawn up.

Abstract: 1,022,554. Bore concentricity gauges. A EISELE. May 6,1963, No. 17783/63. Heading G1H. A gauge for measuring the concentricity of a pair of bores B, C comprises a replaceable gauging member 14 connected to a structure 20 rotatable relative to a stationary structure 18 housing a dial gauge 16. The gauging member 14 has a cylindrical surface 142 which fits snugly but slidably into bore C, and a reduced diameter portion 140 housing a transverse sliding measuring pin 146 having a rounded end 148 to engage bore B and an arcuate edge 150 which engages the inclined surface 136 of a transmission rod 130 slidable in the member 14.

Alternatively the polycondensation product may be incorporated in the reaction mixture for the preparation of the prepolymer, followed by reaction of the prepolymer with the cross-linking agent of M.W. below 500 in a polar organic solvent. Suitable polyhydroxyl compounds are polyesters, polyesteramides, polyethers, polythioethers and polyacetals. Diphenylmethane-4,41-diisocyanates, the isomeric toluylene diisocyanates and hexamethylene diisocyanate are the preferred diisocyanates. The chain extender of M.W. below 500 is suitably water, a glycol, aminoalcohol, diamine, acid hydrazide or hydrazine hydrate.  The N,N-bis-b -hydroxy alkyl derivatives of the monovalent primary amines or the divalent secondary amines may be obtained by adding 2 moles of ethylene oxide, propylene oxide or butylene oxide to amines which products may then be condensed either alone or with a diol. Suitable amines are methyl, ethyl, butyl, isobutyl, dodecyl, stearyl and allyl amines, b -cyanoethylamine, cyclohexylamine, 4-phenylcyclohexylamine, benzylamine, b -phenylethylamine, aniline, toluidines, xylidenes, aminopyridines, amino-quinolines, N,N1-dimethylethylene diamine, N,N1-diethyl ethylene diamine, N,N1 - dimethyl propylene diamine, N,N1 - dimethyl hexamethylene diamine and piperazine.  The polycondensation products may have up to 90% of their nitrogen atoms quaternized by a monofunctional sulphuric acid ester, an aromatic sulphonic acid ester, an aliphatic sultone or an alkyl halide. The preferred organic solvent is N,N-dimethylformamide.
