Title: Method of machine knitting of a clothing blank
IPC: D04B1/24
Filed: 1977-03-23
Abstract: The knitting operation is started on all outer portions (11-15) of the garment blank (10), for example a back portion (11), two sleeve portions (12, 13) and two portions forming front-part halves (14, 15), at the end of the garment remote from the neck and having a fixed margin (16). These outer portions (11-15) are produced simultaneously until the arm-onset height (18) of the garment (10) is reached. The subsequent narrowing shoulder portion (19) is knitted in one piece by means of continuous stitch rows by the progressive shaping of the outer portion regions into one another according to a desired form of the transitions between these regions (19/1-19/5). The collar portion (24/1-24/3) is then knitted on in a one-part or multi-part manner. The garment blank is thus produced, in the desired final form of its portions, by means of stitch wales extending in the longitudinal direction. The capacity of the knitting machine is utilised as efficiently as possible. The completion of the garment requires only minor finishing work and no seams in the shoulder portion (19) which can be provided with a continuous patterning. <IMAGE>

Abstract: 591,122. Photographic plates. COLLINS, R. B., PRATT, O. E., SMITH, R. C. M., and ILFORD, Ltd. May 15, 1945, 12173. [Class 98 (ii)] A process for' decolourising a colloid layer containing a dye salt formed between a dye and a surface active compound comprises treating the layer with an aqueous solution of a compound which is capable of diffusion through the colloid and which forms, with the surface active compound a complex which is more stable than the dye salt, and thereafter washing the layer with water. The coloured layers are produced, as by the method of Specifications 585,372 and 591,124 by applying an aqueous solution of a basic dye to a colloid layer which contains an anion-active compound and, similarly by an acid dye applied to a kation-active compound, and they may form an outer or an inner layer of a photographic element. The treating compound may be one of the surface active compounds described in Specification 591,124, a kation-active compound being used where the colour is produced by a basic dye united to an anion-active cornpound and vice-versa. Other suitable decolourising compounds are sodium silico-dodecatungstate, sodium tannate, quinine sulphate, caffeine and diphenyl guanidine acetate. Specification 591,123 also is referred to.

Title: A new or improved means and method for treating land, for purposes of draining
IPC: E02D3/032
Filed: 1937-04-29
Abstract: 494,732. Implements for working land ; agricultural drainage. EDMONDS, P. J. April 29, 1937, No. 12270. [Classes 6 (i) and 33] Apparatus for making draining channels below the ground comprises a wheeled vehicle carrying an appliance for forming a mole drain and means for feeding sand, cinders or other porous material into the drain. The porous material may be fed through the moleforming appliance, and the land may first be cut by a rotary or other coulter and finally rolled after the drain has been formed and filled. Figs. 1, 2 and 5 show a wheeled vehicle which may be drawn by a tractor and which comprises a hopper 2 having spaced partitions 4 which are also spaced from the bottom of the hopper to form gaps through which the porous material contained in the hopper can escape. The bottom of the hopper is open but can be closed by a movable gate 7. Extending from the bottom of the hopper is a hollow member consisting of side walls 29 and a front sharp-edged member 31 and a bottom member 33 of cylindrical shape having a chisel-shaped edge 33A. The member 33 is hollow and is cut away as shown at 33B. Above the ground level the walls 29 are continued rearwardly by walls 30, the gap between the rear edges of which is closed. A continuous opening 30A, 29A, 33B is thus provided for the outflow of material passing through the bottom of the hopper. In order to lower the mole 33 into the ground, the hopper and its associated parts are mounted on a frame 8 in which are journalled partly rotatable axles 9, the cranked ends 10 of which are journalled in chassis members 11 carrying land wheels 12. On each side of the hopper a structure 13 extends upwardly from the frame 8 and carries a quadrant 14 engaged by a worm 15 on a spindle 16 which is rotated by a chain 17 and a handle 18. Fast on the quadrant 14 is a toggle lever 20, 21 pivoted at its lower end 22 to the crank 10. When the handle 18 and quadrant 14 are rotated, the toggle 20, 21 is broken and the hopper descends relatively to the wheels 12. The depth to which the tool 33 is moved is regulated by a bar 24 pivoted at 23 to the toggle lever and at 25 to a fitting 26 which is pinned to a movable bar 27. Stops 28 limit the movement of the fitting 26. The bar 27 may be provided with holes for receiving a pin forming an adjustable stop. The front of the machine may be provided with a rotary cutter 34 which may consist of a single sharpedged disc or of two spaced discs. A roller 36 may be provided at the rear and centrally of the machine and it may have a shallow V- shaped periphery as shown in Fig. 2. A platform 37 may be provided for the operator.

Abstract: 565,797. Making structural members. TRUSSED CONCRETE STEEL CO., Ltd., and GREEN, D. H. July 29, 1943, No. 12364. [Classes 83 (ii) and 83 (iv)] Angular bending.-A bar 7 is bent into a zig-zag by feeding it step-by-step and, during the intervals, bending it about three fulcrums a, b, c simultaneously, a being fixed, b moving in an arc about a, and c moving axially of the bar. Starting from the position shown, in which a previously bent portion A of the bar is held between correspondingly shaped jaws 16, 17 and another bend B has just been formed, the fulcrum b, in the form of a stud 27 fixed in an arm 26, is moved about a pivot 28 by a cam 33, a slide 30, and an adjustable link 29 to the position shown in broken lines. Directly the stud 27 disengages the bend B, the fulcrum c, which takes the form of an eye 12b, through which the bar 7 passes, carried by a slide 12, is moved to the left by a spring 13 till it engages a stop 12a. The jaws 16, 17 are then separated by cams 21, 22, the rod is advanced by rollers 5 one pitch and the jaws 16, 17 are closed. The cam 33 then swings the stud 27 back into its original position, thus forming another bend, the rod being pressed against the eye 12b and moving it, and the unbent bar, to the right during the process. The advance of the slide 12 may be limited by a stop (not shown). Welding wire fabrics.-While the work is being moved as a whole to the right, two bars 35 may be moved with it, by automatically operated clamps 39 on a reciprocating slide 37, and while the bending operation is taking place and all feeding movements have ceased, the bends, adjacent the bars 35, may be resistance welded thereto by means not shown. In this case the roller feed 5 may be omitted. Two structural elements thus formed may be similarly connected by a third zig-zag to form a trough-section member or by a third and fourth to form a box-section. The bars 7 and 35 may have any desired cross-section.

Abstract: 829,770. Multi-gun cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 9, 1956 [April 29, 1955], No. 12367/55. Class 39(1). In plural gun C.R.T.s a voltage difference is set up between the final anodes of adjacent gun structures to set up an asymmetric field which causes one of the electron beams to be deflected and its arrival angle at the target to be controlled. The anode voltages may vary as a function of scanning voltages to correct for the beam position and the focusing voltage may also vary to give correct focusing at all points of the target. The colour tube has three guns lying in a plane each comprising a cathode 1, a modulating electrode 2 and anode shield members 3, 4, 5, 6, the two outer guns being inclined and the anodes 6 positioned just inside the field free space of wall coating 11 which is connected to the anode 6 of the centre grin. The anodes 5, 6 of the outer guns are connected to a voltage source and potentiometer 14a via combining circuits 17, 18 which apply the potential necessary to produce a permanent deflection and a circuit 19 influenced by the scanning generator and applying a correcting voltage. The final anode of the centre gun may extend a short distance beyond the outer gun, thereby shielding the central beam from the asymmetric fields. Correction for the beams at right angles to the common plane of the guns is achieved by magnetic or electro-static means, no extra shielding means being required. Specification 821,542 is referred to.
