Filed: 1917-05-30
Abstract: 109,237. Gibson, R. L. May 30, 1917. Tools for recording; record tracks, form of.-Relates to methods of recording sound in which liquid is forced through a hollow stylus oscillated by the sound waves and is congealed on a moving record surface, and consists in using a stylus with microscopic aperture and in applying considerable pressure to the liquid so that it emerges with a velocity substantially exceeding that of the record surface and creates a built-up record ridge thereon. Fig. 1 shows the whole apparatus, and Fig. 5 is in section through the stylus. The record blank d is rotated and fed forward in the usual way beneath the orifice a<1> of the glass stylus a. The liquid, such as melted bees-wax or beeswax and paraffin, is contained in a lead or other vessel c having flexible walls, and passes through passages containing cotton &c., past a regulating- valva n and felt washers k', to a bulb a<3> forming the upper part of the stylus and filled with cotton &c. The vessel c is surrounded by an oil jacket o communicating through a pipe o<1> with a source of pressure. An outer jacket p is supplied with steam for heating purposes through a pipe p<2>. The stylus a is seated in a lead washer j, Fig. 5, screwed into a thimble i',' and is held thereon by a spring k acting through a flanged sleeve k<2> and the felt washers k<3>. The thimble i<1> is secured by a threaded collar i<2> to a plate f, which is attached by studs g<1> to the frame g and has a central spherical bearing h in a recess in a member g<2>. The lower part of the passage for the liquid wax is surrounded by separate casings s, s<1> supplied with steam through pipes t, t<1> which allow the temperatures to be separately regulated. The stylus is held against vibration in one plane by a bar u or by wires, and vibrations in a plane at right-angles thereto are communicated to the stylus point through a glass or other filament connected at its opposite end to the diaphragm of a sound-box suspended from a bracket on the plate f. The stylus a is drawn out to a very fine point, preferably after setting it in the thimble i', and the point is then broken off to expose the orifice. The record, if of sufficient rigidity, may be used directly as a matrix for duplicating records by pressure; or a metal die may be formed by a double electro-plating process, as described in Specification' 21183/07.

Title: Process for the preparation of cellulose powder
IPC: B29B9/00
Filed: 1956-03-13
Abstract: A process for the preparation of cellulose powder from cellulose obtained in known manner from cellulosic raw material comprises separating from a suspension of the cellulose a portion containing at least 50 per cent cellulose of fibre length less than 0.2 mm., preferably less than 0.1 mm., and converting said portion to a cellulose powder by dehydration, drying and breaking up any fibre aggregates resulting.  The process is applicable to the waste product called "save-all stuff" resulting from the decomposition of cellulosic raw materials, e.g. hardwood, softwood, and animal plants, portions containing at least 50 per cent cellulose of fibre length less than 0.2 mm., preferably less than 0.1 mm., being separated by either a wet sieving, or a flotation or sedimentation process. Decomposition of cellulosic raw material may be achieved by any known process, e.g. the sulphate or soda-sulphate process, and subsequent bleaching may be done by use of calcium hypochlorite.  Dehydration, drying and breaking up any fibre aggregrates present may likewise be effected in known manner.  Examples are given.ALSO:A process for the preparation of cellulose powder from cellulose obtained in known manner from cellulose raw material comprises separating from a suspension of the cellulose a portion containing at least 50 per cent cellulose of fibre length less than 0,2 mm., preferably less than 0,1 mm., and converting said portion to a cellulose powder by dehydration, drying and breaking up any fibre aggregates resulting. In example 1 an aqueous cellulose suspension is thickened in a screening drum to about 4 per cent consistency.  Filtration through a sieve having an inner mesh width of about 0,3 mm. results in a filtrate containing 0,4-015 g. per litre of fibres, 60 per cent of which are smaller than 0,2 mm.  The short fibres are enriched by flotation to 2-3 per cent stuff consistency and further thickened on a cell filter to a content of 20 per cent dry substance.  In example 2 an aqueous cellulose suspension is placed in a rotating sieve having an inner mesh width of 0,4-0,8 mm.  The filtrate therefrom containing fibres less than 0,2 mm. long is conveyed to a settling funnel, the short fibres being enriched therein by sedimentation, with subsequent dehydration on a cell filter with attached press.  In example 3 "save-all stuff" is conveyed to a thickener having a sieve of about 0,4 mm. inner mesh width and the filtrate containing 0,5-0,7 g. per litre of short fibres, as defined above, is treated as described in example 2.  A cylindrical sieve of inner mesh width from 0,3-0,4 mm. and a cell filter of less than 2 mm. inner mesh are employed in example 4.
