Abstract: 1,042,440. Powder distributers. C. VAN DER LELY N.V. Aug. 30, 1963 [Sept. 25, 1962], No. 34478/63. Heading A1D. A machine for spreading powdered material of the kind comprising a container 7 and an outlet port through which material is fed to a spreading member 11 is characterized in that the outlet port is formed in a portion 18 of the container which is rotatably adjustable by means of an adjusting mechanism and a shutter 49 is located close to the outlet port for opening or closing the outlet port, the shutter being rotatably adjustable by a control mechanism 53, the arrangement being such that operation of the adjusting mechanism to displace the outlet portion causes the control mechanism to move in conjunction with the adjusting mechanism whereby the controlled setting of the shutter relative to the outlet portion remains unchanged. As shown the portion 18 is connected by a link 25 with a casting 26 which is movable by a screw 30 operated by a handle 33. The control mechanism comprises a lever 54 mounted on the casting 26 and cooperating with a scale 56.

Title: The preparation and use of catalytic compositions based on iron compounds
IPC: C01B7/05
Filed: 1965-08-13
Abstract: Ammonia and chlorine are prepared from NH4Cl using a catalyst comprising at least one iron compound, at least one element taken from V, Mn and Zn in compound form or elementary form such that the atomic ratio of the element or elements to the iron is from 0.02 to 0.25, and an alkali metal chloride.  Such a catalyst reacts with NH4Cl according to the equation <FORM:1121671/C1/1> at 400-410 DEG C. and ammonia gas may be removed in a stream of nitrogen.  The chlorinated residue if treated at 500-510 DEG  C. with a stream of oxygen liberates chlorine.  Comparative examples are given.ALSO:Catalysts useful in the preparation of NH3 and Cl2 from NH4Cl comprise at least one iron compound, at least one element selected from V, Mn and Zn in the combined state or elementary form such that the atomic ratio of the said element or elements to iron is 0.02 to 0.25, and an alkali metal chloride. Preferably the composition comprises Fe2O3 and Mn3O4, ZnO or V2O5, and KCl.  The source of Fe2O3 may be bauxite.  An example describes the preparation of a catalyst from iron-loaded bauxite, KCl, Mn3O4 and CuCl3.

A toy having at least one ground wheel has located in the casing of the toy or on its underside a box open in the direction of forward movement into which may enter food lying in the path of movement of the toy. A toy animal has a box 4 underneath and an opening 28 in the base plate 1 through which projects a flexible flap 26 with a metal carrier 27 rotated anticlockwise by a U-shaped crank link 22 and crank 21 on a shaft 15 driven through suitable gearing from a spindle 23, driving the wheels 12. The spindle projects through slots in the crank link 22. The flap contacts the edge 29 of the box and front parts 32 which give a sweeping- along effect to the flap before sweeping up the food in the box. The wheels may be driven by clockwork or by flywheel rotated by pushing the toy on the ground, or by simply pushing the toy along the ground. Depressions in the base of the box or dependent portions on extensions on the side walls projecting to the front of the box, hold the front edge of the box above a rough surface. The tail 5 forms a removable closure for the box. Flexible blades on a driven shaft may alternatively sweep the food into the box. Deflecting plates over the wheels deflect the food from the wheels.

Title: A new or improved domestic contrivance for making woollen and other fabrics
IPC: D03D29/00
Filed: 1920-12-17
Abstract: 174,834. Oddie, J. T. Dec. 17, 1920. Warps doubled and twisted together during weaving, fabrics with; corded fabrics.-A domestic contrivance for making wool and other yarns into fabrics comprises a set of needles 4 which are held in a row by a two-part clamp on a table 1, have their pointed ends projecting towards the operator, and have primary warp threads 8 attached to their eyes ; one or more sets of secondary warp threads 9; one or more sets of looping-threads 13; and one or more weft threads 12. The threads 9, 13, 12, or any desired combination of them are worked on to the needles, and when the needles, which are separated by a comb 5, are full, the work is moved over them on the primary warp threads 8, which are kept taut by weights and form part of the finished fabric. The secondary warp threads 9 are supplied from a bobbin 10 mounted in a frame 11 and are kept apart by a comb 16 mounted on the frame. The looping-threads 13 are supplied in a similar manner. In one method of using the apparatus, the threads 9, 13 are passed between pairs of needles 4 and their ends are held in the clamp which holds the needles. A weft thread 12 is then passed from right to left beneath the needles, whereupon the threads 9 are raised to pass between the needles and secure the weft. A weft is then inserted from left to right and the threads 9 are again lowered into the position shown to secure this weft. The threads 13 are then looped around the needles; another weft is inserted from right to left and the above sequence of operations is continued. By employing looping-threads 13 which cross one another and also the secondary warps and needles, the weft threads may be omitted. By omitting the looping-threads a fabric having a plain weave is produced.

Particulate sodium silicate having a ratio SiO 2 /Na 2 O by wt. of 1 : 1 to 3À6: 1 may be present. At least 15% by wt. of sodium tripolyphosphate is present, the particles being such that no more than 20% pass a 100 mesh B.S.S. test sieve. The sodium silicate solution contains 20 to 50% solids and is used in quantities of 10 to 25% of the composition at a temperature of 35‹ to 75‹ C. Up to 3% of a liquid non-ionic detergent e.g. a polypropylene glycol ethylene oxide condensate may be sprayed on to the mixture before, after or simultaneously with the spraying of the sodium silicate solution. Optional ingredients are conventional colours, perfumes, stabilizers for the chlorinated phosphate and tarnish inhibitors. Specification 1,022,731 is referred to.

[Also in Division B3] A laminated cylindrical matrix is machined to show contour lines. The matrix shown comprises a hollow metallic base 10 having applied thereto plywood layers 18, 19 and 20, the layer 18 extending wholly, and the layers 19, 20 partly, over the periphery of the base. The laminations of each plywood layer are secured together by coloured adhesive interlayers and the plywood layers are secured to each other and to the base by adhesive layers having a colour contrasting with that of the adhesive interlayers. The matrix is machined by cutting, filing and/or grinding to form one or more shaped depressions e.g. 26. The contour lines corresponding to depression 26 are shown at 24 and 25, Fig. 2. The plywood layers may be partly shaped before application to the base. The plywood layers may be replaced by layers of metal or plastic. When machining has been completed, the matrix may be coated with varnish. The matrix roller is for use in reducing the thickness of a sole and for this purpose, the sole is passed between the matrix roller and a presser roller of yieldable material so as to deform the sole into the shape of the depression 26 and while so depressed, the sole is forced edgewise against a knife which trims away the portions of the sole projecting from the depression.

Abstract: 903,100. Selective printing. CREED & CO. Ltd. Oct. 18, 1960, No. 35672/60. Class 100 (4). In a printer in which a print head comprises a series of selectably-operable elements to form any of a number of characters, the separate elements are simultaneously chosen and moved in a straight line path into operative position to effect impression by fluid pressure. The separate elements are chosen by selector means consisting of twenty-five electromagnets 23 operated by a teleprinter or computor code. The selected magnets withdraw pins 36 from below spring-biased pistons 25 in fluid-pressure cylinders 22, and fluid such as oil under pressure is thereby allowed to flow from source 39 to flexible tubes 21. These terminate in the printing head 1 carrying spring-biased impression-forming members 4 slidably mounted in supports 5, 6, 7 and each having a piston portion 15 operating in cylinders 14 bored in a chest 12. The head 1 is mounted on rollers 11 for letter-spacing and carriage return movement. Specification 895,280 is referred to.
