Title: Improvements in or relating to data processing apparatus
Inventor: MASON FREDERICK PERCIVAL
Filed: 1958-11-27
Abstract: 879,187. Transistor switching circuits. CREED & CO. Ltd. Dec. 10, 1959 [Nov. 27, 1958], No. 38302/58. Class 40(6) [Also in Group XVI] A positive potential 32 is connected to output lines 37 or 38 upon the opening or closing of contacts 20a. With contact 20a open, as shown, no potential from 3 is present and transistor 28 is non-conducting, but because of invertor 34, transistor 29 is conducting. Similarly because of flip-flop 36, transistor 30 is conducting and transistor 31 is not. When contacts 20a close transistor 28 conducts and there is a path through transistors 28 and 30 until the delay unit 35 causes transistor 30 to be non-conducting and so cuts off potential from line 37. When contacts 20a open a similar action occurs to present a potential to line 38.

Title: Improvements in or relating to methods of and devices for joining floor coverings
IPC: B29C65/54
Filed: 1963-09-30
Abstract: 1,014,111. Seaming non - metallic sheet material. S.E.T.E.P. SOC. D'ETUDES DE RECHERCHES ET D'EXPERIMENTATIONS INDUSTRIELLES DE TOUS PROCEDES NOUVEAUX POUR L'ALLIANCE DES TEXTILES ET DES MATIERES PLASTIQUES. Sept. 30, 1963 [Oct. 2, 1962], No. 38334/63. Heading B5K. Floor covering strips of the type comprising felt sheets coated with plastic material are joined by protecting the surface of the strips along their adjacent edges, and injecting unheated glue into a gap between the covering strips to be joined, the glue being injected into the gap at floor level until the glue rises to the top surface of the strips to completely fill the gap. Each covering strip comprises a felt sheet 3 reinforced by a fabric 4 having a plastic surface layer 5, e.g. of polyvinyl chloride, the sheet 3 being secured to a cement floor 1 by a glue layer 2. The gap between adjacent covering strips is widened by a cutter, Figs. 2 and 4, having a blade 7 formed at its lower end with transverse cutting fins 8 to cut the portion of the felt adhering to the layer 2 or to the floor 1. This step is unnecessary if joining is effected before the glue has set completely. To facilitate removal of the glue on the top surfaces of the layers 5 two parallel adhesive tapes are applied one on each side of the gap by apparatus, Fig. 5, comprising a metal plate 32 which is inserted vertically into the gap 11 to act as a guide as tape is unrolled from coaxial rolls 9. Coaxial knurled rollers 10 press the tape on to the surface of the layers 5. Glue is delivered from a cylinder 14, Fig. 7, by gas pressure acting on the face 16 of a piston 16. A connector 23, Fig. 8, is screwed on to an end cap 22 of the cylinder 14. On depression of a hand lever 24 a valve 25 is opened and glue is injected through a head 27, similar in shape to the head of the cutter shown in Figs. 2 and 4, into the bottom of the widened gap of adjacent covering strips and injection is continued until the glue rises to the top surface. The head 27 is formed with radial grooves to facilitate distribution of the glue. The glue output may be adjusted by a plug 26. The glue preferably consists of a vinyl acetate emulsion containing from 2-4% of a polyvinyl chloride solvent or, alternatively, may consist of an emulsion of vinyl acetate and acrylic resins. After injection of the glue the surface of the join is pressed by a cylindrical roller, Fig. 10 (not shown), having a slightly knurled or grooved surface. After setting of the glue the adhesive tape is removed.

Title: Process for the preparation of lubricating grease compositions
Filed: 1956-12-18
Abstract: Lubricating grease compositions are prepared by a process which comprises: (1) mixing an aqueous inorganic colloid with a liquid (including molten and dissolved) surface-active agent; (ii) adding an hydrophobic lubricating oil to the mixture under turbulent flow conditions for between 0.05 and 5 seconds at between 150 DEG  and 250 DEG  F. so that water separates from oily curds; (iii) passing the mixture over a perforated surface through which the separated water drains; and (iv) dehydrating the oily curds by passing them as a film between 0.005 and 0.03 inch thick over a surface of skin temperature between 320 DEG  and 370 DEG  F. for from 1 to 30 seconds.  The inorganic colloids are either clays or amorphous colloids such as silica, alumina, lime, magnesia and combinations thereof.  Suitable surface-active agents are amines and ammonium compounds with at least one aliphatic hydrocarbon chain of at least 8 carbon atoms, e.g. dodecyl, heptadecyl and octadecyl amines, and dimethyl dioctadecyl, dimethyl dihexadecyl or dimethyl octadecenyl octadecyl ammonium chlorides, bromides and acetates.  Cyclic amines, e.g. heptadecylimidazolin, polyamines and the amido amines derived therefrom with carboxylic acids e.g. amyl, aliphatic or animal fatty acids, tall oil, naphthenic and rosin acids (C8-36), and their hydroxy derivatives are also suitable as are the fatty acid amido amines of the condensation products of ammonia with epihalohydrins. The lubricating oil may be a mineral oil or any water-insoluble synthetic oil such as alkylated aromatics, e.g. t-butylated naphthalenes; polyolefines, e.g. polyethylene and polybutylene; aliphatic diesters of C4-12 dicarboxylic acids and C2-16 monohydric alcohols; aliphatic and aromatic esters of phosphorus acids such as phosphates, phosphonates and phosphinates; polyoxyalkylene fluids, silicones, tetraalkyl silicates and halohydrocarbons, examples being bis(2-ethylhexyl) sebacate, bis(n-butyl) adipate, trioctyl phosphate, tricresyl phosphate, dioctyl cresyl phosphate, dimethyl and methylphenyl silicones, tetrabutyl, tetrahexyl and tetraoctyl silicates, hexachlorobutadiene and chlorofluorocarbons.  In an example Hectorite clay is degangued in cyclone separators, modified with phosphoric acid and then treated with a melted surface-active agent (the condensation product of epichlorohydrin and ammonia wherein 1/3 of the amine groups are acylated with tall oil acids) and hot mineral lubricating oil added under turbulent flow conditions. The final dehydration is achieved in a thin-film turbulentflow dehydrator, e.g. a tube surrounded by a heated jacket, the grease film being passed along the inner surface of the tube by means of rotating parallel vanes concentrically placed therein.  Suitable speeds of rotation are between 1000 and 2500 R.P.M. in the case of a temperature of 320 DEG  to 370 DEG  F. and residence times of 1 to 30 seconds.
