Filed: 1956-04-30
Abstract: 854,880. Etching; transferring designs. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 30, 1957 [April 30, 1956], No. 13191/56. Class 100(2) A method of forming conductors on an insulating support comprises the step of applying to the conducting layer on an insulating base an etching resist material in the form of a transfer. An etching resist of wax or a bituminous or readily polymerisable material is carried in the required design on a flexible temporary support e.g. of paper. The resist is transferred by heat and pressure to an electrically conducting layer on an insulating support. The conductor layer not covered by the resist is removed by etching. If the temporary support is porous, it can be left in position during etching. The resist can be polymerised or hardened after transfer by the application of air and heat. For providing conductors on both sides of the insulating support, the temporary support 3 is provided with resist 2 and is folded along lines 5, 6 so as to engage both sides of the insulating support, which is provided on each side with a conducting layer.

Title: Improvements in or relating to the refining of wood pulp
IPC: D21C9/08
Filed: 1936-05-09
Abstract: A method of refining wood pulp, for use in the manufacture of rayon or as filler for moulded articles, comprises treating the pulp in aqueous suspension with chlorine in the presence of an alkali metal chloride, and washing the pulp with soft water.  The chlorination may be an essential step in a bleaching operation, e.g. when operating on unbleached sulphite pulp.  The treatment has the effect of reducing the alkaline earth content of the pulp which after treatment contains less than 0,025 per cent CaO and less than 0,005 per cent MgO.  The reaction is preferably carried out at high density, e.g. 5 per cent. The temperature need not exceed 40 DEG  C. and the reaction is normally not longer than 30--90 minutes.  In an example, unbleached pulp containing 0,15 per cent CaO is treated for one hour at 20 DEG C. and a density of 3,5 per cent with 2 per cent gaseous chlorine and 2,5 per cent sodium chloride calculated on the fibre weight. The pulp is then washed with water substantially free from lime and contains not more than 0,01 per cent CaO.  In a second example, a bleached pulp containing 0,08 per cent CaO and 0,02 per cent MgO is treated at 5 per cent density for \ba1/2\be hour with 0,75 per cent C12 and 1,5 per cent potassium chloride calculated on the fibre weight.  The chlorine is added as chlorine water containing 4 grams C12/litre. The pulp is then washed with water free from calcium or magnesium and contains 0,01 per cent CaO and is practically free from magnesium.

Title: Improved process and apparatus for coating finely divided and like material
IPC: A61K9/50
Filed: 1929-05-01
Abstract: 310,855. Maynes, H. F., and Maymes, E. C., (Assignees of Zebulske, E. A.). May 1, 1928, [Convention date]. Coatings for medicines; pillmaking appliances.-A process for coating finely divided material with a liquid coating comprises forming a spray of the coating liquid by means of compressed air, introducing the divided material into the spray, and maintaining the coated particles in suspension until the coating has dried or hardened. The application of the process to coating medicinal pills or pellets with chocolate, sugar, or other suitable coating material is referred to. As shown in Figs. 1 and 2, the apparatus is designed for coating a dried mixture of milk and sugar contained in a receptacle S, with chocolate that is liquified in a pressure kettle K. The liquified chocolate is forced by air under pressure through a pipe 9 to the inner nozzle 26 of a mixing device N, the powdered material being supplied through a pipe 2 to the mixing chamber 36. Compressed air from the pipe 15 is supplied to the kettle through a pipe 11, and to the member N through pipes 13, 14. When the valves 42, 43 are opened to admit compressed air through the pipes 14, 13 to the mixing nozzle, the needle valve 44 being open, the molten chocolate delivered through the tube 26 is converted into a fine spray by the compressed air issuing from the tube 21, this spray being carried out of the nozzle through orifices 30, 37. The cut-off valve 48 of the pipe 2 is then opened, and the partial vacuum that exists in the mixing chamber 36 induces a flow of material to be coated from the container 1. The supply of this material is regulated by the provision of openings 38 through the mixing chamber to the atmosphere, As the spray of coated material leaves the mixing chamber 34, 36 a converging annular blast of air delivered through the pipe 41 to the sleeve 39 surrounding the cap 35 serves to narrow the stream of spray and avoid its contact with the walls of the drying chamber D before the chocolate has become dried or set. The velocity of the stream of spray is reduced owing to the diverging walls 54 of the chamber D and the dried coated material is received by the canveyer 55. In the mixing nozzle N the tube 26 is centred by a screw 27 having a spring mounting 28, and the tube 21 is provided with openings 31 through which the compressed air passes to the interior of the cap 29. The injector action of the nozzle may be used to supply the granular material and the coating material without a gravity feed for the material in the container 1 or the use of compressed air to the chocolate container K. According to a modified arrangement which is illustrated, the mixing and spraying nozzle N is arranged horizontally, the coated material being sprayed into a hopper supplied with compressed air by rotary blower and received in a separator.
