Title: Improvements in the manufacture of synthetic resins
IPC: C08G12/12
Filed: 1931-02-10
Abstract: Synthetic resins in powder form are prepared by condensing urea and formaldehyde in aqueous solution at ordinary temperature in the molecular proportion of 1 : 2, removing the water, and mixing the dry product with a formaldehyde-fixing agent in quantity sufficient to give a molecular ratio of urea plus formaldehyde-fixing agent to formaldehyde in the product of 1 : 1,5-1,75.  Urea, thiourea and resorcinol are mentioned as formaldehyde-fixing agents.  The pulverulent products may be moulded under heat and pressure.  Fillers such as wood flour, asbestos, sulphite or paper pulp may be added, being preferably incorporated with the solution before drying, which may then be effected in a shelf or rotary kiln drier.  In the absence of a filler, the solution may be spray-dried or may be evaporated to a viscous mass, a volatile inert liquid such as an alcohol added and the whole expanded in a vacuum.  The drying does not necessarily require the application of heat.  Advantageously, a plasticizer in small or large quantity is added before or after drying, e.g. a phenolaldehyde, m-toluene-sulphonamide or glycerolphthalic acid resin, together with a solid organic acid to assist the final moulding operation.ALSO:Synthetic resins in powder form for moulding under heat and pressure are prepared by condensing urea and formaldehyde in aqueous solution at ordinary temperature in the molecular proportions of 1 : 2, removing the water, and mixing the dry product with a formaldehyde-fixing agent, e.g. thiourea, resorcinol, or further urea, in quantity sufficient to give a molecular ratio of urea plus formaldehyde-fixing agent to formaldehyde in the product of 1 : 1.5-1.75.

Title: Improvements in or relating to methods of improving the dry-spinning qualities of aqueous casein solutions
IPC: D01F1/10
Filed: 1943-03-17
Abstract: A small amount of oleic acid or a saponaceous substance containing the radical of oleic acid is added to an aqueous casein spinning solution which is then dry spun to form artificial filaments.  The oleic acid or oleic acid compound may be present to the extent of 1 per cent or more of the weight of the dry casein.  In an example, the spinning solution comprises casein, caustic soda, oleic acid, and water, and the temperature of spinning is 31-45 DEG  C.  Other examples describe the spinning of similar solutions at temperatures of 23-55 DEG  C.  The spinning speed may vary from 5-120 metres per minute.  In another example, the saponaceous substance is sodium oleylmethylamino-ethyl sulphonate.  The addition of the oleic acid or oleic acid compound facilitates the spinning operation and enables satisfactory spinning to be carried out over a wider range of temperature.  The Specification as open to inspection under Sect. 91 comprises also the addition, to any albuminous dry spinning solution, of common soap, soap with modified fatty acid residue, fatty alcohol sulphonate, fatty alcohol ester of a mineral acid, or other surface active material, or a non - ionogenetically active washing material. This subject-matter does not appear in the Specification as accepted.

Title: Method and apparatus for filtering liquids
IPC: B01D37/00
Filed: 1966-02-02
Abstract: 1,108,371. Travelling-band liquid filters. BELSON CORPORATION. 2 Feb., 1966 [17 Feb.. 1965], No. 4693/66. Heading B1D. A mixture of solid and two liquids of different specific gravities is fed at 36, Fig. 1, to the upper run of an endless conveyer belt 16. on which upper run a sheet of filter paper 40 is conveyed from a roll 41 of it on the right to a disposal receptacle 42 on the left of the apparatus. Each end of the belt is raised above the level of the intermediate portion, and fixed sealing strips are provided at the sides, so that a pool P of unfiltered material forms. Filtrate is collected in a closed chamber 10 having a perforate top 11 (along which the conveyer belt passes), a filtrate outlet 37 to a pump and pipeline for re-use e.g. as machine-tool coolant, and an upper outlet to a vacuum pump 45. The air withdrawn by the pump is used to supply jets 55 directed at a small angle to the surface of the pool to displace the upper of the two liquids towards one (raised) end or the other of the conveyer. Where the upper liquid is a demulsified coolant oil which needs to be reused, it is displaced towards the incoming portion of filter paper (on the right) so that it is filtered therethrough and received in the filtrate chamber, and the filter paper is dried by induced air, before the filter paper enters the pool where it filters the lower of the two liquids. The lower liquid in this case is coolant emulsion which is immiscible at this stage with the upper coolant oil. The filtered oil is again dispersed in the filtered emulsion in the pump and pipeline on the way 'back to the machine tool. Where the upper liquid is a "tramp" oil, e.g. a lubricating oil whose presence in the coolant is deleterious, it is displaced towards the outgoing portion of filter paper for collection on the filter cake and ultimate disposal. The lower liquid is again a coolant emulsion. In Fig. 5, (not shown), the filter paper is replaced by an endless band of filter medium. It is cleaned by jets of air or steam located in a gap formed between the medium and the conveyer belt at the left of the apparatus. Movement of the conveyer belt in all cases is (a) initiated 'by a pressure-responsive switch communicating with the filtrate chamber and operating a clutch.
