Title: Improvements in or relating to mopping devices for washing and sponging floors, walls, window-panes and other surfaces
IPC: A47L13/14
Filed: 1950-02-03
Abstract: 672,049. Mopping devices. OMBREDANE, L. G. Feb. 3, 1950 [Feb. 8, 1949; March 4, 1949], No. 2857 / 50. Class 19. A mopping device for washing and sponging floors &c. is characterised by a body consisting of a plate bent to form two parts at right angles to each other and pivotally connected to a handle, a washing element arranged in the body, a movable plate fixed to at least one cross-shaft or rod passing through the washing element and bent portion of the body and a control rod pivotally connected to said cross - shaft and guided along the handle by means of a guide member. When the washing element supported by the body is in its washing position, the body is substantially at right angles to the handle while, in its sponging position the washing element after pivoting about its pivotal connecton with the handle is substantially parallel to the handle so that when the control rod is pulled the movable plate is pulled towards the bent portion of the body thus compressing the washing element. In the Figures the body consists of a sheet-metal member a, a' and a washing element f of syn-, thetic or natural sponge. A cross-shaft p passes through the washing element. The rod p is guided through a member m and has its opposite end screw-threaded at. i so that a plate c may be clamped between two nuts h, h<SP>1</SP>. This plate is used for pressing the sponge body during the sponging operation. The device may be fixed to a handle i through members c and b, both of which are pivotally interconnected through a pin d. A rubber strip may be fixed to the lower edge of plate e to improve the cleaning action of the device. A. control rod u slides through a guide member r and is connected by its end w to the cross-shaft p. Other modifications of the implement are described.

Title: Improvements in or relating to resilient rubber-like compositions
IPC: C08J3/11
Filed: 1933-01-30
Abstract: Resilient rubber-like masses are made by dissolving at elevated temperatures an insoluble polymerized vinyl halide (chloride, bromide or iodide) in a medium capable of dissolving the halide only at temperatures considerably above room temperature, and causing the composition to gel by cooling it.  Examples of suitable solvents are chloronaphthalene, o-nitrodiphenylether, dibutylphthalate, tricresylphosphate, benzylbenzoate, a mixture of 2 parts of o-nitrodiphenylether, 1 part of m-dinitrobenzene and 1 part of dinitrotoluene, a mixture of equal parts of tricresyl phosphate and dibutylphthalate, etc.  Fillers, pigments and other compatible plastics may be incorporated.  In examples (1) one part of polymerized vinyl chloride is dissolved in 2 parts of o-nitrodiphenylether at 180 DEG  C. and cooled; (2) 8 parts of polymerized vinyl chloride are dissolved at elevated temperature in 3 parts of tricresyl phosphate and 3 parts of dibutylphthalate and cooled.ALSO:Resilient rubber-like masses are made by dissolving at elevated temperatures an insoluble polymerized vinyl halide (chloride, bromide or iodide) in a medium capable of dissolving the halide only at temperatures considerably above room temperature, and causing the composition to gel by cooling it.

Void [Published under Sect. 91 of the Act]. Locating conductors by determining the equipotential lines in a portion of subsoil traversed by an alternating current. Induced currents in the loop formed by the two sounding-members 5, 6 driven into the soil, the telephone 7, and the connecting wires are neutralized by the inclusion in the circuit of a coil 8 movable about two axes at right-angles. In a modification, the coil is movable only about the vertical axis formed by one of the sounding-members 5, and its plane is adjusted by an optical device at each observation so as to coincide with that of the two sounding-members 5, 6. In this arrangement, the product of the area of the coil 8 and the number of turns thereon is arranged to be variable so that it may be made to coincide with the area of the loop 5, 7, 6. Alternatively the area of this loop may be adjusted by varying the distance apart of the sounding-members 5, 6.

Title: Delay electric blasting caps
IPC: F42B3/16
Filed: 1954-02-02
Abstract: 739,929. Blasting fuzes. CANADIAN INDUSTRIES (1954), Ltd. Feb. 2, 1954 [Feb. 28, 1953], No. 3002/54. Classes 9(1) and 9(2). An electric blasting device is provided with a delay element placed between the igniter and the detonating charge, the element being a metallic cylinder 4 containing a fuze composition 5 arranged in a spiral. Fig. 1 shows a metal shell 1 of copper or aluminium, into which is introduced a base charge 2 and a priming charge 3 such as a lead azide-lead styphnate mixture. The delay cylinder 4 is of lead and above it is a matchhead 6 connecting lead wires 7, 8 which extend through a plug 9 of sulphur asphalt, rubber or other plastic insulating materials. The delay element may be made by drawing down a lead tube filled with the fuze composition, sealing the ends of the tube, then winding the tube on a mandrel with adjacent turns in contact. The mandrel is then removed and the helix cut to the required length and swaged in a die to produce the solid cylinder 4. The fuze composition may be 70 per cent red lead, 16 per cent silicon and 14 per cent silica. In a given example the swaged tube is wound around a piano wire to produce a helix of outer diameter 0À250 with 7 to 8 turns per inch. The wire being removed, the spiral is cut into 1À2 inch long sections which are placed in a steel die and pressed under a load of 600 pounds. A solid cylinder 0À92 inches long is thus produced and inserted in a copper shell containing a base charge of tetryl. The delay period can be altered by changing the length of the spiral or altering the fuze composition. An alternative composition given is 69 per cent potassium permanganate, 29À5 per cent antimony, 1À5 per cent boron. In place of the matchhead, a loose charge of igniting composition such as 70 parts red lead and 30 parts silicon may be used. The mandrel used to form the spiral may be of soft metal and allowed to remain within the delay element and be compressed with it.

Title: Process for rolling sheet metal
IPC: B21B1/38
Filed: 1928-01-31
Abstract: 304,921. Tytus, J. B., and Eppelsheimer, D. Jan. 31, 1928. Rolling; cold-rolling, cross-rolling.-Sheet metal is rolled by a succession of steps from the hot slabs including cold rolling. The hot slab is first rolled in a continuous mill. The product is then cut into lengths either single or sufficient for doubling and is rerolled cold in a direction transverse to the original rolling without removing the scale. When doubled pieces are rolled they are introduced into the pass with the doubled edge first cross-rolling being omitted. The pass pressure at this stage is such that the resulting product is convex. A pack is then formed with the convexities in line and after reheating is rolled with the crests of the convexity in line with the direction of rolling. The pack rolling may be effected in a continuous mill.

Abstract: 1504201 Intersecting gill boxes H NAMOTTE 24 Jan 1975 [25 Jan 1974] 3187/75 Heading DIN In an intersecting gill box the faller bars in the upper and lower runs are spaced apart from each other such that the distance between centres of adjacent faller bars is not less than twice the thickness of a bar. This is said to allow a faster throughput of fibres and also allows the span between the driving worms to be greater. As a result, the drawing means 7, 8 can be located closer to the gilling zone between the ends of the worms, the worm ends being mounted in ball bearings. The supply cylinders 14, 15, 16, Fig. 6 are mounted an adjustable distance D from the gilling zone and their speed is adjustable to suit that of the fallers.
