Title: A process of impregnating fabrics with soaps
IPC: D06M13/184
Filed: 1931-08-06
Abstract: Fabrics are waterproofed with an emulsion of a fatty acid or resin soap of a polyvalent metal, such as aluminium, magnesium, zinc or lead, which has been stabilized by forcing it under high pressure through small holes or slots.  A waterproofing substance such as paraffin wax, montan wax, bitumen or beeswax may be incorporated therewith.  As emulsifying agents albumen, glue, gelatine, casein, gum arabic, carrageen moss, starch, and dextrin may be employed together with wetting agents such as aliphatic or hydro-aromatic alcohols, ketones, amines, esters, &c.  When a waterproofing substance is added, the emulsion is preferably heated and, on setting, is emulsified again with water.  In an example, an oil soap is stirred with bone glue swollen with water and the resultant liquid diluted with water.  Aluminium formate in solution is then added and the solution homogenized, a small amount of butyl alcohol, acetic ester or acetone being finally added.
Patent GB-796139-A (GB)
Title: Improvements in or relating to processes for producing decoration pliable sheet material by depositing metal from the vapour state thereon
IPC: C23C14/04
Filed: 1955-08-04
Abstract: A decorative effect is produced on pliable sheet material that has pronounced projections and cavities by depositing metal thereon from the vapour state in a high vacuum. the metal vapour impinging on the surface of the material at an angle of substantially less than 90 degrees to the surface so that a greater amount of metal is deposited on one side of the projections than on the other side.  Two different metals may be successively deposited, the first at an angle of 90 degrees and the other at an acute angle of, say, 15-50 degrees, or alternatively, at opposite slants when opposite sides of the projections are locally coated with each metal.  Materials which may be coated are textile fabrics, particularly those which have been dyed and which consist of cellulosic, animal or synthetic fibres, paper, leather and plastic foils.  The projections and cavities may be obtained by local shrinking or embossing.  The adhesion of the metal coating may be enhanced by subsequent heating.  The examples disclose the embossing &c. and coating of cotton percale, cotton satin, silk repp, nylon toile, and polyvinyl chloride foil, with various metals.  Specifications 774,439 and 796,138 are referred to.

Aug. 11, 1932, 22492. [Class 38 (iii).] Varying E.M.F.-The driving motors of an electric strip propulsion system are supplied with different values of constant current from a generator, and the value of this constant current is changed by varying the connection of one or more of a plurality of separately excited field windings of the generator, relatively to the supply. In the system shown, a separately excited winding 14 on the generator 1 is disconnected, when the motors 5 overspeed, by operation of a differential relay 27 which is energized from D.C. lines 19, 20 and a tachometer generator 31. When increased output of the generator 1 is desired, a second separately excited winding 15 is energized by closing a switch 34. Alternatively, the windings 14, 15 may be arranged normally in series and placed in parallel for increased output. Means may be provided for limiting the duration of increased output, and the setting of the overload protective means in the generator circuit may be changed with operation of switch 34.

Title: Improvements relating to machines for making sheet material from a pulp
IPC: G05D16/18
Filed: 1947-08-15
Abstract: 643,582. Suction control in paper-making machines. SULZER FRERES SOC. ANON. Aug. 15, 1947, No. 22727. Convention date, May 29. [Class 96] [Also in Group XXIX] A machine for making sheet paper from pulp, has suction applied at various points 3, 6, 11, 17, Fig. 1, connected by pipes 19 ... 22 respectively to a suction pump 23, and includes regulating valves 31 ... 34 in the pipes, which valves are operated by control valves actuated by the suction in the pipes so that the suction pres. sure at the pump is maintained at a permissible minimum value when the suction points are not covered by the sheet. The valves 31 ...34 are byepassed by pipes 35 ... 3E respectively, .which have adjustable throttle valves 39 ... 42 tc enable the desired suction to be maintained at the pump when the valves 31 ... 34 are closed. These valves 31 ... 34 each comprise an expansible bladder 51, Fig. 2, con nected through a valve 53 with either atmosphere through a pipe 54 or suction through a pipe 55 Pipes 43 ... 46 connect each chamber 56 with the pressure in each suction pipe and the chamber below each valve is open to atmospheric pressure. When the suction in any pipe 19 ... 22 reaches the required value, the appropriate valve 53 rises to connect the bladder to suction, whereupon a spring 59 deflates the bladder; and when the suction decreases, the valve drops to connect the bladder to atmospheric pressure, whereupon the bladder inflates. In a modification, the valve 67, Fig. 3, is locked in a position, to cause the bladder to inflate, by a spring-loaded piston 73. When suction is applied to the rear of the piston through a pipe 76, the lock is withdrawn and a spring 77 moves the valve 67 to deflate the bladder. Each valve is pulled manually to the locked position before the machine is started. The releasing of the lock of each valve is timed by a device comprising a cylinder 80, Fig. 4, having connections 91 ... 95 with the corresponding pipes 76, Fig. 3, and a pipe 96 connected to the pump. The distances between the connections 91 ... 95 correspond to the times the sheet takes to travel from a respective suction point to the next. A piston 81 extended by a rack 83 is driven to the right by pinions 86, 85 and 84, in timed relation to the speed of the machine, -to open the connections 91 ... 95 to suction. The pinions 86, 85 are pivoted on a handle 87 which drops away from the pinion 84 when the rack completes its stroke. In another arrangement, the pistons 73, Fig. 3, may be actuated by fluid pressure.
