Title: Improvements in or relating to methods of closing in a vacuum-tight manner and opening in a hollow body
IPC: C03C27/04
Filed: 1967-04-06
Abstract: 1,134,914. Jointing; soldering. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 6 April, 1967 [9 April, 1966], No. 15894/67. Headings B3R and B3V. [Also in Division H1] A method of sealing an opening 3 in a hollow body 1 by means of a plate 4 secured in a grooved ring 5 by sealing material 6 comprises placing the sealing material in pulverulent state along the edge of the plate, subjecting the hollow body to the action of a vacuum pump 13, heating the body to a temperature exceeding the softening temperature of the sealing material until the vacuum in the hollow body reaches a maximum, and ensuring that the sealing material solidifies before it can be sucked into the hollow body. Cavities in conductive or insulating bodies may be sealed, and the sealing material may be a vitreous material, a thermohardening or thermoplastic synthetic resin, or a solder, e.g. Ti-Ni, Cu-Au or Cu-Sn. An alloy solder may be used in which one of the constitutents is in excess of the eutectic ratio. The edge of an insulating covering plate 4 may be metallized before soldering. As applied to closing the resonant cavity 3 of a reflex klystron having a copper body 1, a mica plate 4 is secured by a sealing glass 6 in the ring 5, which is formed in a ferrochromium or fernico ring the expansion coefficient of which matches that of the glass. The body 1 is heated by a ring 7 which is heated by high-frequency currents, although burners may be used. When the glass 6 melts air-leak past the plate is eliminated and the vacuum rises to a maximum.

The flanged shell is an integral part of a mounting bracket 32, and the sleeve is rotatably mounted in a central boss 30 of the shell ; the outer end of the spring is attached to a stud 36 screwed into the periphery of the shell. A disc 44 carried by the sleeve completes the casing for the spring. The spindle 15 is hollow and is rotatable in a fixed sleeve 16 which is integral with a second mounting bracket. A boss 13, which carries arms 12 to which is attached the flanged drum 10, is screwed on to the part 14 of the spindle and has a stuffing-box 18 between it and the fixed sleeve 16. The interior of the spindle communicates with a hose connection 27, and with the water supply by means of a passage 26 in the bracket 17. The initial tension in the spring may be changed by removing the peg 40, turning the sleeve 29 and re-inserting the peg.

[Also in Divisions B1-B2 and C3] A process for producing a flat-shaped, air- and-water vapour-permeable and water-absorbing article of microcellular structure, comprises forming a mixture containing a substantially water-insoluble vinyl polymer, a plasticizer therefor and an aqueous solution of a watersoluble film-forming, macromolecular polymer of a vinyl compound, subjecting the mixture to the action of shearing forces, applying the mixture to a sheet of carrier material, removing the water present under conditions such that no bubble formation takes place, gelling the vinyl polymer present by heating, removing the water-soluble polymer by washing with an aqueous liquid and drying the product. The carrier material may be removed from the microcellular structure and the sheets may be provided with a leather-like grain by embossing before washing out the water-soluble polymer and may also be printed, shaded or lacquered after washing. The sheets may be laminated to various kinds of fibrous webs such as woven and knitted fabrics, fleeces and felted webs or to plastics foils which have been rendered air- and water-permeable before or after removal of the water-soluble polymer, for example by dot printing with an adhesive such as a solution of a vinyl chloride homo- or co-polymer. The water-soluble polymer may be polyvinyl alcohol, or a copolymer of vinyl alcohol of a partly saponified polyvinyl ester. Part of the watersoluble polymer may be replaced by watersoluble, film-forming non-vinylic polymer such as a salt or polyacrylic acid, starch or an algenate. The water-soluble polymers may be plasticized by addition of compounds such as polyalcohols, e.g. glycerol. The insoluble polymer may be a homo- or co-polymer of vinyl chloride such as vinyl chloride/vinyl acetate copolymers. Numerous suitable plasticizers are specified, such as linear polyurethanes, butadiene-acrylonitrile rubber, butadiene/acrylonitrile/styrene copolymers and polyacrylic acid esters. Pigments and dyeing agents may be present in the water-insoluble polymer, such as carbon black, chrome yellow, molybdate red and metal bronze pigments. Various other additives such as foaming agents and fillers of which many are specified may also be present.

In one form a cylindrical container has an open-ended compartment beneath flanges 9, 10, Fig. 1, of the base 1, for the blade or blades, the handle 12 being held in a groove 13, the. head, with one of the handle sections 8 fitted on to it being held between the lid and a groove 6 in the body. The base has an upstanding flange circumferentially threaded with gaps opposite the recesses for the blades, handle and head, and the lid flange has similar, gaps so that the lidmay be secured by a single turn. In another form shown in Fig. 4, the handle is supported in a compartment above the head. In another form the case is square and the handle lies diagonally across in a compartment above those for the head and blades as shown in Fig. 6.

Abstract: 1,124,950. Automatic exchange systems. ERICSSON TELEPHONES Ltd. 30 March, 1967 [15 April, 1966], No. 16596/66. Heading H4K. [Also in Division G4] A translator for converting short codes individual to each calling subscriber (and representative of frequently wanted subscribers) into exchange dialling codes comprises an array of exchange code storage units, one for each short code of each subscriber, and means for selecting a corresponding one such unit by the simultaneous application to that unit of signals identifying a calling subscriber and a short code received from that subscriber. As shown the storage units each comprise a wire 1, 2, 3 &o. threading those cores in an array which corresponds to the digits of an exchange code. Each wire links 2 out of 5 cores of each row and thus stores one digit per row in that code. According to the dialled short code received the marker energizes 1 out of N relays thus closing one contact 1C1---NC1. The marker also identifies the calling subscriber by similarly closing one contact 1M - - - PM. A contact H2 is subsequently closed discharging a capacitor K through the selected wire and effecting the required read out. The digit A for example is read out as a pulse on 2 out of 5 wires A 1  to A 5 . The pulses each trip a corresponding transistor bi-stable and thus set a corresponding relay of a staticizer. These relays have contacts connected to give an output in I out of 10 code. In another form not shown, each storage unit comprises an electroluminescent plate and an array of photo-cells separated by an opaque mask apertured at points corresponding to selected photo-cells and representative of the exchange digits. A first marking signal causes the plates of all storage units appropriate to a received code to glow while a second marking signal enables the output of all storage units individual to the calling subscriber, thus only a single storage unit selected by the co-incidence of these two signals operates to give the appropriate exchange code.
