Title: Improvements in paper and processes of making the same
IPC: D21H17/35
Filed: 1924-04-07
Abstract: 234,245. Dicker, S. G. S., (Rubber Latex Research Corporation). April 7, 1924. Paper, treating with special materials; boards and compound paper; coated paper. - Paper, pulp board, and pulp articles are treated with a solution of latex stabilized in known manner as bv the use of ammonia or other alkali and then dried in such manner as to solidify the latex solids into a dried irreversible gel. A caoutchouc product is formed which is structureless and practically homogenous, quite distinct from tough and short coagulation rubber. Unsized or slightly sized paper from the rolls of the paper machine is passed through a bath of diluted latex, the excess is preferably removed by squeezing rolls and the paper dried by hot rolls. If thick paper is used, drying under vacuum or reduced pressure is desirable, in which case too early extraction of the ammonia, and the resultant acidity and coagulation of the latex must be avoided. A surface impregnation or a graded impregnation may be obtained on one or both sides by using paper more or less moist. Duplex wrapping paper may be produced by using a latex gel bond for two sheets. Where a clinging film of latex is left on the paper, the film, whilst tacky, may be used to secure a facing of finely-divided material such as china clay, soapstone, talc, '' agalmatolite," &c. The tackiness may be produced by a slight raising of the temperature of the paper. The void spaces left in the treated paper may be reduced either by repeated impregnation or by hot pressing to cause the rubber film to bond. Latex may be used with most alkaline sizing materials and also with some of a neutral character. A vulcanized product may be obtained by incorporating colloid sulphur with the latex mixture, or, better, by using ammonium sulphide or polysulphide as the stabilizing agent. Paper treated as above may be subsequently frictioned with rubber in the production of paper-covered fabrics. To facilitate impregnation, the paper may be moistened with either water, alcohol, ether or other volatile liquids. Rubber produced in paper according to this process contains somewhat more proteid or nitrogenous matter than ordinary rubber.

Title: Improvements in or relating to a method for supplying fuel to a free piston engine and to an engine for putting this method into operation
IPC: F02B71/00
Filed: 1960-03-11
Abstract: 898,727. Free piston engines. BURTON, E P. March 11, 1960 [March 11, 1959], No. 8741/60. Class 7(2). The invention relates to a free piston engine in which a rich mixture is compressed and then forced into the engine cylinder during the compression stroke. In Fig. 1 mixture formed in a cylinder 11 is forced through the valve 13 into the engine cylinder 1. The degree of compression in the cylinder 11 is higher than that in the cylinder 1. For supplying air to the auxiliary cylinder 11 there is preferably used an air source at a higher pressure than that of the air which is conveyed to the scavenging ports 2. The injection device may be replaced by a carburetter or diffuser feeding into the ports 16. A further charge of air may be injected into the cylinder 11 at the beginning of the compression stroke this injection being effected by means of a valve which may be mechanically or pneumatically controlled. In Fig. 2 the machine comprises two motor cylinders 1a, 1b. In this case the auxiliary cylinder 11 a is placed laterally between the two motor cylinders which communicate with each other by a channel 23. In Fig. 3 the valve 13a can be controlled for example by a cam carried and/or driven by the synchronizing device. The quantity of fuel conveyed is regulated by varying the richness of the air/fuel mixture introduced into the engine cylinder which can be easily effected by suitably adjusting the carburetter or other device for regulating the quantity of fuel supplied. The machine may comprise means for regulating the effective area of the inlet ports into the auxiliary cylinder in which the fuel mixture is compressed and the regulating members can be controlled by an engine speed sensitive member for example one of the synchronizing devices for both movable assemblies. In the embodiment of Fig. 3 the engine may comprise one or two engine cylinders.
