Title: Method of metallizing textiles
IPC: D06Q1/04
Filed: 1955-07-13
Abstract: Textiles that have been metallized by vapour deposition in high vacuum are heated at a temperature exceeding 100 DEG C. to increase the adhesion of the metal coating.  Prior to the metal deposition the textile may be coated with a thin layer of a natural resin, e.g. shellac or colophony, or with a film-forming polymerization resin of which several examples are given.  Textiles consisting of natural and artificial cellulose fibres may be subjected to a treatment for reducing their swelling properties before being metallized.  The fabric may be provided with permanent mechanical calendar effects before metallization, and metal patterns may be produced (i) by printing the fabric with a water-soluble resist paste, metallizing, and washing to remove the paste, or (ii) by printing the fabric with a solution or emulsion of a water-insoluble natural or synthetic resin, depositing the metal, and washing the metal out of the unprinted areas, the fabric being exposed prior to metallization to a glow discharge.  The temperature of the final heating step is preferably 120 DEG -240 DEG C. for natural and regenerated cellulose and 120 DEG -190 DEG C. for cellulose derivatives.  Specifications 774,223 and 774,439 are referred to.

Abstract: 387,341. Deep-well pumps. DIETZ, F., 46, Ludwigstrasse, Nuremberg, Germany. July 24, 1931, No. 21262. Convention date, Nov. 3, 1930. [Class 102 (i).] In a deep-well oil pump means are provided for flushing the valves and valve seats to remove sand, and for operating the valves positively. The valves and valve-seats are made of tungsten carbide. By lowering the bucket 3, Fig. 1, the discharge valve 4 is lifted by a plunger 5 in the casing 6 of the suction valve. The depression of the plunger 5 causes a plunger 8 to raise the suction valve 9, thus allowing the oil to run back and flush the valves. In addition, flushing liquid may be supplied through the rod 2, Fig. 5, by a surface pump operating in synchronism. During the downstroke the liquid depresses a plunger 15 and so opens a valve 16, past which the liquid flows to passages 20, 21. The depression of the stem 17 of the valve 16 causes a plunger 18 to rise and lift the discharge valve 4. The suction valve 9 is opened during the suction stroke by a plunger 14, operated by oil supplied by a pipe 11 from the pressure space above the bucket. Both valves can be opened, to allow the oil to run back, by lowering the bucket until the plunger 5 raises a plunger 32, thus causing the plunger 18 to lift the discharge valve. The depression of the plunger 5 causes the descent of plungers 26 carried by a ring 27. The latter depresses a plunger 28, thus causing a plunger 29 to rise and lift the plunger 14.

Class 40 (7) A directive antenna system consists of a parabolic reflector 1 with a waveguide 7 extending through the vertix of the reflector in the direction of the axis and coupled to primary elements at the focus consisting of two horns 3 and 4 by means of slots 8, 9, each horn being intended to illuminute half the surface of the reflector. The walls of the horns nearest the guide 7 may be coincident with the waveguide wall but are preferably arranged as in Fig. 4 to obtain the most even illumination of the reflector. The length of the horns is made small to reduce the shadow caused by them. To avoid mis-match due to energy reflected back into the horns a phase plate may be mounted on the surface of the reflector round the wave guide of such size and thickness that energy reflected back to the horn through it cancels energy reflected back from the rest of the reflector. To reduce the size of the wave guide and horns; these may be filled with a solid dielectric medium. Only one of them may be so filled if this assists in matching the two. Matching of the horns to the waveguide is also effected by varying the widths of the coupling slots 8, 9 and in order to obtain a purely resistive load a reactive waveguide extention 10 and/or an iris 11 in the guide may be used.
