Title: Reinforced resinous structural material
IPC: B29C70/20
Filed: 1955-09-09
Abstract: 825,004. Sheet material composed of agglutinated fibres or threads; laminates. MINNESOTA MINING & MANUFACTURING CO. Sept. 9, 1955 [Sept. 9, 1954], No. 11409/55. Class 140. A method of producing resinous sheet material reinforced with glass filaments comprises combining continuous glass filaments treated to render the surface resin-receptive, into a flat compact layer in substantial linear alignment; passing the layer under even tension through a bath of solvent-free liquid resin binder composition which is rapidly thermosetting at a temperature higher than that of the bath until the layer is saturated; squeezing the resultant resin-impregnated web and solidifying the resin composition sufficiently to provide a flat flexible non-porous sheet the resin component of which is potentially fusible and heat-curable to a hard tough resin finely bonded to the filaments. Glass filaments may be employed in the form of narrow beams, yarn, tow or rovings, each strand or bundle consisting of a large number of individual filaments. The filament bundles may be untwisted or lightly twisted. The filaments may be drawn from the spinneret orifices by rapidly rotating drums, treated with a primer composition, grouped into bundles and condensed into a dense flat layer and then heated by radiant heated bars just prior to contact with the resin. After passing through the resin bath the web is passed through squeeze rolls to provide complete wetting of the glass surfaces by resin, and then immediately treated to solidify the resin (e.g. by cooling with a chilled air blast). Layers of the sheet may be superimposed in the form of multiple laminations which may be lightly bonded together to produce pre-forms from which desired end-products may be formed by pressuremoulding or otherwise. Specified resins are epoxide resins formed, e.g. by reaction of epichlorohydrin with bisphenol A in the presence of caustic soda; or epichlorhydrin with glycerol in presence of boron trifluoride with subsequent addition of alkali. Curing agents and catalysts may be incorporated in the resin composition. As shown (Fig. 1) webs of untwisted or lightly twisted filament bundles are brought together between guide rollers 10 and 11 and condensing comb 12 and over a series of uneven bars 13 to form a dense flat permeable sheet 14 of continuous glass filaments. The sheet passes between radiant heaters 15, through trough 16 containing the resinous composition 17 in liquid fused form, then through a three roll calender, after which it is cooled by fans 20 and wound up on drum 21 together with a temporary separation sheet 22 from supply roll 23. Fig. 2 shows sheet material according to the invention, wherein the individual filaments 24 are surrounded by resinous composition 25, the approximate location of the filament bundles as initially introduced into the sheet being indicated by boundary lines 26. Specification 619,674 is referred to.

Title: Improvements in or relating to electric discharge tubes
IPC: H01J35/16
Filed: 1937-04-21
Abstract: 478,926. Discharge apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. April 21, 1937, No. 11443. Convention date, April 23, 1936. [Class 39 (i)] An electric discharge tube comprises two or more independent vacuum vessels which are each provided with at least one metallic tubular extension which is closed at or near its end by a metallic foil or tag, the vessels being con. nected by arranging the tag of one exten. sion of one vessel close to or engaging the tag of one extension of a second vessel, hermetically interconnecting the two extensions, for example by soldering, and finally per. forating the tags. In the X-ray tube shown in Fig. 1, the anode and cathode are contained in separate metal compartments 1, 2 respectively, provided with extensions 9, 10 closed by metal foils 11, 12, as shown in detail in Fig. 2. The foils may be of constantan, 50 microns thick. The compartments are evacuated independently, and possibly the cables 7, 8 are connected up and their insulating collars 5, 6 sealed into the glass re-entrant stems by hardening material. The extensions 9, 10 are fitted together, the air trapped between 11, 12 passing out through hole 13. The joint 14 and hole 13 are sealed, for example, by solder, and the foils are perforated by passing a beam of electrons at 100-200 kilovolts through them. A window 32 for the X-rays is provided. Discharge tubes having' intermediate tubular electrodes may be made in the same way, each electrode being in two parts closed by foils. The foils may be perforated mechanically, as shown in Fig. 3, in which the extension 9 has an extensible corrugated portion 15 surrounding a hollow tubular mandrel 17 with a sharpened end, sliding in the member 16. A nut 21 enables the corrugated portion to be compressed, when the tubular mandrel, which has a shoulder 18 pressed against the end of extension 9 by a spring 19, is driven forward through the foils 11, 12. To prevent possible blocking of the mandrel by the detached foils, the mandrel is given an inclined edge which is rounded in the region 23. The foils are thus not completely severed but are bent back against the wall of extension 10 and lie in the recess 31 in the mandrel. The construction may be applied to cathode - ray tubes. To remove gases liberated during the perforation of the foils, a getter may be placed in one of the compartments preferably in the field-free space within the cathode shield.

Abstract: 273,664. United Products Corporation of America, (Assignees of Biddle, A.). July 3, 1926, [Convention date]. Latex, coagulating; plastic compositions.- Articles of non-conducting water-absorbent materials are prepared to receive an electrolytic deposit of metal by coating with an aqueous colloidal dispersion of rubber, applying a film of finely divided conducting material and dehydrating the colloidal coating. Wood, paper, fabrics, and leaves may be so treated. The colloid may consist of natural rubber latex,. slightly concentrated, if necessary, or may be prepared by dissolving rubber in benzol and making an aqueous dispersion by agitation or mastica. tion. Excess material may be removed in a. centrifugal machine. The coating is dried until tacky, and provided with a film of graphite or powdered copper, bronze, silver or antimony. Alternatively the colloidal coating may be completely dried and the conducting film applied over a second colloidal coating. The first colloidal coating may be dehydrated by dipping in an alcohol or other coagulant instead of by evaporation. An acid copper sulphate solution may be used as plating electrolyte. In some cases this may also form the coagulating agent. Clay, zinc oxide, sodium silicate, casein or other proteinous or albuminous colloids or mixtures thereof may be added to the latex to impart any desired consistency. A suitable colloid consists. of 100 parts rubber latex (35 per cent rubber), 50 parts clay, 100 parts zinc oxide, 30 parts water. The clay is preferably made alkaline with ammonium borax or lime. The latex preparation may contain sulphur or other vulcanizing agent, and accelerating or retarding agents. After vulcanization a second coating of the colloid or a coating of another adhesive is necessary before applying the conductive material. The conductive material may in some cases be dispersed in the colloidal material; when the latex contains sulphur, the conductive material may be graphite or antimony but not bronze. Moulds for receiving detachable metal deposits may be formed from a plastic substance consisting of colloidal preparations as described above in which are incorporated filling materials such as clay, wood, pulp, fibre or pulverized cork or asbestos. Softening oils, waxes or resins may be added if necessary. The material is moulded to the required shape and dehydrated or coagulated and the conductive coating then applied. The die or mould may be given a thin coating of oil to facilitate detachment. Alternatively the conductive material may be applied to the mould so as to become embedded in the plastic material. According to the Specification as open to public inspection under Sect. 91 (3) (a) an anode adapted to receive a deposit of rubber from rubber latex consists of a conductor provided with a coating of an irreversible colloid in aqueous dispersion containing bicarbonate of soda or ammonium carbonate which is afterwards heated to liberate gas which renders the mass porous. This subject matter does not appear in the Specification as accepted.

Abstract: 770,936. Telephone exchange systems. WESTERN ELECTRIC CO., Inc. April 22, 1955 [April 29, 1954], No. 11694/55. Class 40 (4). In a system of the type described in Specification 704,108 in which connections are set up over a plurality of stages of cross-points by means of markings extended over the stages a " propagator " or amplifying circuit for the marking is provided between some of the stages, said propagator circuit being shunted by a oneway device arranged to be non-conducting whilst the marking is being extended, but conducting when the circuit of the succeeding stage is completed. As shown, a connection between a telephone set 10A and a trunk 11A is established by an operator via three stages of gas diodes 12, by applying marking potential to the telephone circuit and ground to the trunk circuit. Enabling potential is also applied to intermediate stages over switches 20 and anode potential for the propagator circuit is provided over switch 32. Tube 12A fires to the marking, thereby raising the potential of the anode of tube 12B which also fires. The resulting rise in potential of the point 23A however is not high enough to fire a further diode; but when it is applied together with a suitable bias to the striker of tube 26A the latter fires and the resulting anode-cathode current raises the potential of the point 24A to an accurately determined voltage sufficient to fire the tube 12E. This voltage is also sufficient to back-bias the shunt rectifier 37A. When, however, tube 12E fires, the potential of point 24A falls and rectifier 37A is forward-biased to complete the connection over the succession of gas diodes. The enabling potentials are then removed by switches 20 and switch 32 removes the anode supply from tube 26A which is extinguished. Specification 686,427 also is referred to.

Title: Improvements in cam-operated devices for glass shaping machines
IPC: C03B9/40
Filed: 1939-04-21
Abstract: 527,814. Glass manufacture. MITCHELL, W. B. April 21, 1939, No. 11990. [Class 56] Relates to cam-operated slides and similar devices used in a glass-shaping machine, particularly the mechanism for opening and closing moulds which are mounted on a table that rotates relatively to stationary cams. According to the invention, a piston rod of a fluid-pressure cylinder is connected to the sliding part and the cylinder is fixed to a relatively stationary part. The slide is moved in one direction by fluid pressure and in the reverse direction by a cam in opposition to the fluid pressure. The pressure exerted by the fluid remains constant and it provides a resilient connection that allows the moving parts to yield and prevent breakage if the movement in one direction is obstructed. The fluid may be the compressed air supply used in the machine, or it may be liquid stored in a pressure accumulator. In the construction shown, a finishing-mould table 6 is mounted on a machine table 2 that rotates about a central column 3. The mould table 6 is secured to the piston rod 7 of a cylinder 9 and is provided with an arm 6a that engages a stationary cam 4 having a single operating-surface. The cylinder 9 is secured to the table 2. As the machine rotates, the cam 4 moves the table 6 to open the mould, and the pressure in the cylinder 9 closes the mould when the surface of the cam 4 recedes from the column 3.
