Title: An improved method and apparatus for the manufacture of louvred corrugated sheeting
Inventor: GREEN EDWARD RAMSAY
IPC: B21D13/04
Filed: 1960-05-19
Abstract: 907,318. Making expanded and like openwork metal. VENTREX ROOFING Ltd. May 18, 1961 [May 19, 1960], No. 17737/60. Class 83 (4). A method of making louvred corrugated sheeting consists in feeding a corrugated sheet past a rotating part carrying a tool or tools which is or are arranged to effect, successively or simultaneously, at spaced locations along a crest or valley of each of a number of corrugations, a shearing operation to form a cross-cut across each crest and a pressing operation to form a hood-like louvre on one side of the cross-cut. Apparatus for performing the method comprises a frame 16, 17 supporting two shafts 12, 13 which are geared together. The shaft 12 is mounted in fixed bearings 14 and the shaft 13 is mounted in two movable bearings 15 and can be adjusted relative to the shaft 12 by a screw 19 and worm-wheel 22 associated with each bearing and a common worm 23. On the feed side of the rolls is a cross-beam 28 the upper face of which is corrugated to correspond to the corrugations of the sheet and which carries shearing inserts which co-operate with shearing tools on the upper roll 10 to form cross-cuts in the valley of the corrugations. Each of the shafts 12 and 13 is of non-circular cross-section and has mounted thereon a number of mildsteel rings each having a bore which corresponds to the shape of the shaft, and a circumferential groove 49 of rounded contour which merges with a convexly curved portion so that the assembled rollers is corrugated in longitudinal cross-section. Each side face of each ring has four slots 51 which co-operate with the slots in adjacent rings to form recesses which accommodate shearing and forming tools 25, 26. The complete assembly is clamped by a nut 62. The upper roll 10 carries projecting tools 25 which have an involute curved surface 41, and a trocoidal end face 43 which meet to form a shearing edge which co-operates with the shearing inserts. There is also a flat lip forming portion 46. The roller 11 has co-operating female tools having corresponding parts 42, 44 and 47. After the sheet has been sheared the portion 8 is formed by the surfaces 41 and 42 of the tools 25 and 26 to a louvre with a straight inclined summit, and a lip 6 is formed by the surfaces 46 and 47. The plate is held down to the beam 28 by spring-loaded rollers 32 and co-operating rollers 33 in fixed bearings 39. Each tool 25, 26 can be adjusted radially by a screw-operated wedge which bears on a flat surface of the shaft (Fig. 4 not shown). In a modification the upper roll 10 is mounted in adjustable bearings and provision is made for forward and backward movement of the part carrying the inserts. In a second modification the forming tools may be separate from the shearing tools and mounted on a further pair of rollers which follow the shearing rolls. In a third modification the rolls may be solid and have recesses to accommodate the tools. Specifications 731,453 and 834,474 are referred to.

Title: Improvements in or relating to glasses for vehicle lamps
IPC: F21V5/00
Filed: 1933-06-22
Abstract: 408,113. Vehicle lamps. BOSCH AKT.- GES., R., 4, Militõrstrasse, Stuttgart, Germany. June 22, 1933, No. 17748. Convention date, June 24, 1932. [Class 75 (ii).] Lantern, fronts.-A front glass for a vehicle lamp, adapted to produce a substantially uniform illumination over a relatively wide angle by means of an ordinary parabolic reflector, is formed with separate groups of vertically disposed grooves or flutings of different dispersive power, each group producing a beam of light which does not substantially overlap its neighbour, the axes of the said beams radiating at different angles from a focal point, and the groups which produce the lateral beams being of prismatic cross-section. In one form, both the parabolic reflector and the glass of the lamp are slightly downwardly inclined and the rear face of the glass is formed with a central field of cylindrical flutings 9, Fig. 3, which produce a pair of beams YXP, Fig. 11, an upper field of prisms 7, 8 which produce a pair of beams PXQ, and a lower field of prisms 10 which produce a pair of beams QXR, the axes of these beams being disposed at approximately 5‹, 25‹, and 40‹ respectively to the axis XY of the lamp. The front face of the glass is formed with vertical cylindrical flutings 5, which are staggered with respect to, and of somewhat larger radius of curvature than, the flutings 9, so as to blend the six beams together, with or without horizontal cylindrical flutings 6 of greater radius of curvature than the flutings 5 and disposed opposite the prisms 10 so as to cause a weak dispersion upwards and downwards of the beams which are strongly deflected laterally. In modifications, the prisms 7, 8 may be combined, the groups of flutings may be disposed side by side, and the flutings 6 may be replaced by downwardly refracting prisms. The glass may be flat or of spherical curvature, or it may be V-shaped in plan so as to reduce its wind-resistance. Fig. 7 shows a glass formed with an overhanging part 11 which may be frosted or formed with flutings 13 to disperse the upwardly directed rays.

Title: Process for dyeing and printing acetate artificial silk
IPC: D06P3/40
Filed: 1937-06-28
Abstract: Cellulose acetate, dyeing; azo dyes.-Acetate artificial silk is dyed or printed with the use of water-soluble azo dyestuffs of the general formula <FORM:0487725/IV/1> wherein R is the residue of a diazo component of the benzene series free from solubilizing groups and R1 is H or methyl, and wherein the diphenylamine complex may carry a further substituent other than a nitro group.  Such dyes are obtainable by coupling the diazotized component with the diphenylamine carboxylic acid or by coupling it with aniline or a nuclear-substituted derivative thereof other than a nitraniline and condensing the product with a halogen benzoic acid.  In examples, acetate artificial silk is dyed by treatment for 1/2 to 1 hour in an aqueous bath at 70-75 DEG  C. containing the dyestuff (1) 4-nitraniline, 2-chloro-4-nitraniline, 2 : 6-dichloro-4-nitraniline or 2 : 4-dichloraniline --> diphenylamine-2-carboxylic acid with or without common salt; (2) 4-nitraniline, 2-chloro-4-nitraniline or 3-chloro-4-aminophenyl-methylsulphone --> 21-ethoxy-diphenylamine-2-carboxylic acid.  A sample has been furnished under Sect. 2 (5) of a dyeing of acetate artificial silk with the sodium salt of the dyestuff, 2 : 4-dichloraniline --> diphenylamine-4-carboxylic acid.  21 - Ethoxydiphenylamine - 2 - carboxylic acid isobtainable by condensing 2-chlorobenzoic acid with 2-phenetidine.  Diphenylamine-4-carboxylic acid is obtainable by splitting off the acetyl group from the product of oxidation with potassium permanganate of N-acetyl-4-methyldiphenylamine.  3 - Chloro - 4 - aminophenyl - methylsulphone is obtainable by treating o-chloraniline with ammonium sulphocyanide and bromine (cf. Specification 257,619, [Class 2 (iii)]) to obtain 3-chloro-4-aminophenylsulphocyanide, decomposing this with caustic soda (cf. Specification 306,590, [Class 2 (iii)]) to obtain 3-chloro-4-aminophenylmercaptan, converting this into the methyl thioether by means of dimethyl sulphate and oxidizing the product with hydrogen peroxide.  The Specification as open to inspection under Sect. 91 comprises p  also the use of the dyestuffs derived from diphenylamine-3-carboxylic acid (obtainable by splitting off the acetyl group from the product of oxidation with potassium permanganate of N-acetyl-3-methyldiphenylamine).  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to apparatus for counting and bundling envelopes or the like
IPC: B65B27/08
Filed: 1956-06-11
Abstract: 804,209. Endless conveyers. WINKLER, R., and DUNNEBIER, K. June 11, 1956 [Sept. 26, 1955], No. 17966/56. Class 78 (1). (Also in Group XVII] A machine for assembling envelopes in batches and wrapping a paper &c. strip round each batch includes a. continuously moving conveyer having pockets into which envelopes are fed to form the batches, the pockets have springy front and rear walls which are deflected during filling to facilitate separation of batches. The envelopes are fed from a stack 1 by a belt 40, or by rollers 41, to a feed wheel 2 for deposition in the pockets. As the pockets approach the filling position their rear walls 21a contact first a stop 23, under which they slip after bending to be arrested by a pawl 22. As the conveyer moves on, the mouth of the pocket at the filling position is thus widened and the front wall 21b of the following pocket contacts the rear wall held by the pawl and is likewise deflected. The walls 21b are additionally deflected by cam means 24a, Fig. 3, operating on their connections 20b with the conveyer chains. When the pocket has received its quota, the pawl 22 is moved permitting the arrested walls to spring forward, the front wall of the following pocket thus advancing sufficiently to ensure that the next envelope will be deposited in it. The pockets carry the batches over a settling and aligning agitator 4 to the wrapping position where dogs 11 on a conveyer 12 lift the batches out of the pockets into contact with paper strip for wrapping (see Group XVII). In order to ensure uniformity of numbers in each batch, the feed wheel 2 is scanned by a photo-electric device 25, Fig. 1, operating means 31 to eject a batch containing less than the prescribed number from the assembly table at a later stage. The front and rear pocket walls are carried on separate pairs of conveyer chains adjustable relative to each other to vary the capacity of the pockets.
Patent GB-657430-A (GB)
Title: Improvements relating to the colouring of glass yarns and fabrics
IPC: C03C25/475
Filed: 1948-07-05
Abstract: Glass yarns or fabrics, without any previous etching treatment, are impregnated or printed with a solution of cellulose in cuprammonium hydroxide or a cellulose ester solution, containing a dyestuff or substance capable of developing a dyestuff, and the cellulose is then regenerated or the solvent is evaporated, leaving a thin coating of regenerated cellulose or cellulose ester on the fibres of the yarn or fabric.  The cellulose ester solution may be a solution of cellulose xanthate and it may contain a sulphuric ester of a leuco vat dye. After impregnation, the glass yarns or fabrics may be passed through a coagulating bath containing an acid with or without an addition of sodium or lead sulphate or other coagulation assistant, and containing also an oxidizing agent.  The dyestuff is thus developed during the process of coagulation and regeneration of the cellulose. Viscose containing dye lakes or pigments may also be used.  Glass yarns or fabrics which are uncoloured or which have already been coloured by this process may be printed with a thickened cellulose xanthate solution containing dyestuffs of the kinds used for printing natural or regenerated cellulose fibres, fixation being effected by treatment with a coagulating bath.  In an example, the yarn or fabric is impregnated with viscose containing Soledon Scarlet BS, and then treated with a solution of sulphuric acid and sodium nitrite to regenerate the cellulose and develop the dyestuff.  The material is then washed, treated with dilute sodium carbonate solution, washed, and dried.  In another example, the viscose contains Monastral Blue, and in another example, the glass yarn or fabric is printed with a paste comprising Indigosol 04B, and viscose, the material then being treated with sulphuric acid and sodium nitrite.  The Provisional Specification describes also the printing or impregnation of glass yarns and fabrics with solutions of cellulose or cellulose esters containing no colouring agent, dyeing being effected after regeneration of the cellulose or evaporation of the solvent.  A solution of cellulose acetate in an organic solvent may be used.
