Title: Improvements in or relating to conveyors
IPC: B65G23/00
Filed: 1949-06-03
Abstract: 680,538. Reciprocating and step-by-step conveyers. GENERAL ELECTRIC CO., Ltd., and HARPER, R. June 5, 1950. [June 3, 1949] No. 14984/49. Class 78 (i). A conveyer consists of two conveying parts, each arranged to move to and from a treatment position such that they carry an article to and from said position until the article is removed therefrom. Thus articles placed on the first part are carried to and from the position and may be removed at said position for treatment, after treatment the article being placed on the second part. An endless belt 1 is mounted on end rollers 2 and 3, the latter being driven by a reversible motor 4. Two abutments 10, 11 on the lower run operate in turn a reversing switch 14 controlling motor 4 so that the belt is reciprocated. The belt is divided off into coloured bands A, B of length equal to the amplitude of the movement and an operator for operating on the articles moved by the belt is situated opposite each band at one end of the movement so that he is opposite a differently coloured band at the other end of the movement. Articles are placed on the belt at the righthand end and move to the first operator who removes them onto a work table 5 or 6 as required since if left on the belt they merely reciprocate backwards and forwards away and towards him. The first operator places articles dealt with back on the belt when at the righthand end of its movement so they pass to the next operator who also removes them as desired when they approach him or may allow them to accumulate on the belt. The articles, which may be carried in containers thus pass along to the left-hand end of the belt where they are removed. Alternatively, the belt may be divided longitudinally as shown by a guard 51 and articles placed at the front on the righthand end will then travel via operators on table 5 to the left-hand end where they are transferred by a plough 61 to the rear of the belt and pass back via on table 6 to the right-hand end of the belt. When articles are removed at the left-hand end the containers may be returned to the right-hand end on the lower run which is provided with pivoted flaps 7 so as to arrest movement in one direction and so cause a step-by-step return movement. The containers are discharged from the lower run by a plough 8. If a particular operator is to be bypassed pivoted gates 9 may be swung across the belt thus preventing return movement of the articles and so causing them to be moved on to the next operator.

Title: Improvements in and relating to electrical ignition systems
IPC: F02P15/00
Filed: 1950-06-15
Abstract: 671,794. Ignition systems. SMITSVONK N. V. June 15, 1950 [July 1, 1949], No. 14985/50. Class 7(iv) In an electrical ignition system comprising a spark plug 16, Fig. 1, at least two condensers 9, 10 and means, such as a transformer 6, 8 for charging the condensers, there is provided means, such as electromagnetic switch 15, 17, 18 which enables the condensers to be successively discharged through the spark plug 16 in order for each to produce an igniting spark there across, the discharge of each condenser, except that of the last one, causing the discharge of the next condenser. Energization of the primary transformer winding 6 is effected by operation of the contact breaker 3 in order to charge condensers 9 and 10 through rectifiers 11, 12 and 13. Upon condenser 9 attaining a given voltage an adjustable spark gap 14 breaks down and the condenser discharges through switch coil 15 and produces the first spark at the discharge type sparking plug 16; energization of coil 15 closes contacts 17, 18, thereby permitting condenser 10 to produce the second spark at the plug. The switch may operate instantaneously or with a time lag. In a modification, a further condenser and relay are provided so that three sparks occur at the'sparking plug. In a further modification, condenser 9, Fig. 3, discharges through relay coil 15 and sparking plug 16, the energization of coil 15 closing contacts 17, 18 and connecting a battery 30, which may be the same as that connected to primary winding 6, to the coil of a time-lag relay 24 whereupon closure of its contacts 26, 27 enables the condenser 10 to discharge through the coil of relay 19 and the sparking plug 16 and so close contacts 20, 21 which thereby connects the battery 30 across the coil of another time-lag relay 25 to close contacts 28, 29 and complete the discharge circuit of condenser 22. so producing a third spark at the plug. The timelag relays may have an adjustable delay. The relays may be replaced by spark gaps or gas discharge tubes, either of which may include controlling electrodes. Specification 651,592 is referred to.

Title: Method of, and means for, producing grained effects on painted surfaces
IPC: B05D1/32
Filed: 1950-06-20
Abstract: A grained effect is produced on a painted surface by applying a coat of scumble to a dried undercoating, covering the coating before it is set with protective sheet material except at selected areas thereof, <PICT:0686415/III/1> applying a material which has been rendered, or is, paint-absorbent to the outside of the protective sheet so as to removed the unprotected areas of wet scumbling and then removing the protective sheet.  Referring to the drawings, scumbled surface A while still wet has applied thereto stencil sheet B of sized paper which may be coated with sand on the contact surface, which is then wiped over with absorbent pad D which has been wetted with a paint solvent, or with a felt covered roller, so removing the scumble from the openings C.  Alternatively a sheet of absorbent material such as paper mach<\>e having embossed areas supplementary to openings C may be pressed on top of the stencil so as to absorb the scumble.

Title: Improvements in or relating to the production of wool-like fibres of cellulosic origin
IPC: D04H1/4266
Filed: 1938-05-26
Abstract: 517,464. Artificial silk; cellulose derivatives. WALLACH, R. May 26, 1938; Nos. 15793 and 17070. [Class 2 (ii)] Cellulosic textile fibres of wool-like character are obtained by applying to loose cellulosic fibres, reagents in a non-uniform or irregular manner so as to convert the cellulose or cellulose derivative of the fibres to a cellulose compound of different chemical composition while maintaining the fibrous structure, the conversion being effected at irregularly spaced intervals throughout the length of the fibres. Irregular application of the reagent may be effected by spraying the fibres with a solution of the reagent. The treated fibres have a permanent crinkle and show irregularity in the physical fibrous structure. To facilitate the conversion the fibres may be treated with swelling agents. Natural or artificial fibres including continuous filaments and staple fibres may be treated. Natural fibres include those from sisal, hemp, jute, flax, kapok, palm, coconut, ramie, china-grass, seaweed, cornstalk, or cotton. Artificial fibres include those of cellulose esters and ethers, and regenerated cellulose. Swelling agents which may be used include organic or inorganic bases, alkaline salts, organic or inorganic acids, zinc chloride, or thiocyanates, for cellulose materials, and acetone, esters, methylene chloride, ethyl alcohol, or di-ethylene glycol, for cellulose ester materials. Cellulose materials may be converted to cellulose esters or ethers including carboxylates, xanthates, and thiourethanes. The cellulose may be condensed with aldehydes, quaternary ammonium compounds, urea, pyrrole, pyridine, piperidine, or pyridinium compounds. Cellulose fibres may be treated, e.g. by spraying a solution of octadecyl-oxymethyl pyridinium chloride and then heated to a temperature above 90C. so as to cause the cellulose to combine with the decomposition products. Cellulose ester materials may be subjected to saponification treatment, e.g. cellulose triacetate fibres may be converted non-uniformly or irregularly along their length into cellulose diacetate. A cellulose ether may be subjected to further etherification, or to esterification. If desired the chemical reagent may be applied uniformly to the fibres and the activity of the reagent may be modified in an irregular manner along the length of the fibres. The treated fibres may be used in the production of fabrics, felts, filter material, diaphragms, and moulded articles. In an example, cellulose hydrate staple fibres are sprayed with caustic alkali solution while they are spread out in a thin layer. They are then treated with ethylene chlorohydrin. Specifications 233,704, 332,263, [both in Class 2 (ii)], and 498,763 are referred to.
