Title: Improvements in glass-to-metal seals
IPC: H01J5/42
Filed: 1945-02-21
Abstract: 585,324. Metal-to-glass seals. BRITISH THOMSON-HOUSTON CO., Ltd., and SCOTT, W. J. Feb. 21, 1945, No. 4408. [Class 36] A method of making a terminal member for a vacuum or other electrical device, such as a condenser or transformer, having conductors 2 secured by glass-to-metal seals consists in pre-forming the seals in one or more rows in a strip of metal 1 from which the separate members with the requisite number of seals are cut. The strip may be formed of suitable alloys, such as nickel-iron-cobalt of the kind described in Specification 358,934, [Group XI]; or, flanged eyelets of such alloys may be welded &c. to an ordinary metal strip at the actual seal-locations. As shown in Figs. 2 and 3, the conductors may be positioned through punched-up eyelets in the strip by a jig 4, small glass tubes 5 threaded on the conductors being subsequently fused to produce the seals (Fig. 3). In the modification shown in Fig. 4, the strip 1 is formed with a groove 7, continuous or otherwise, and the conductors 2 are assembled between pairs of glass rods 8 which are then fused to effect the seal.

Title: Method of locating sound-reflecting objects in water
IPC: H04B11/00
Filed: 1966-02-01
Abstract: 1,139,494. Acoustic wave transmission systems. ATLAS-WERKE A.G. 1 Feb., 1966 [6 Feb., 1965], No. 4436/66. Heading H4D. In a method of locating objects underwater using an acoustic echo arrangement in which comparatively narrow band acoustic pulses are transmitted whilst the received reflected acoustic pulses have a comparative broad band due e.g. to relative movement between the transmitter and the objects or when a broad reception band must be employed in arrangements in which the frequency of the transmitted pulses is not foreseen in advance the receiver is arranged to produce an output signal with a fixed centre frequency. Fig. 2 shows an embodiment in which signals received by a transmit-receive transducer 1 are supplied to a band-passfilter 17 which selects the frequency range in which useful signals are expected to occur and supplies them to a mixer 5 together with a constant frequency from a source 7 and to a further mixer 4 having the output of mixer 5 as a second input. The output of mixer 4 thus comprises the spectrum of the received signals having a constant centre frequency equal to that of source 7. The useful signal in this spectrum, assumed to be very narrow, is then selected by band-pass-filter 11 and fed to a known indicator or control device 12. The effective reception band-width is thus equal to that of filter 17 whilst the signal-to-noise ratio is determined by the narrow passband of filter 11. The receiver may form part of an echo sounding arrangement in which switch 16 alternatively connects the transducer to the receiver and to a transmitter 13 controlled by a pulse generator 14 or the receiver may operate with signals received from an independent source. In addition to the rejection of broad-band interference by filter 11 the specification proposes a method of reducing interference due to reflections of the transmitted energy by the sea-bed and water surface (termed area reverberation) and by, distributed particles (termed volume reverberation) utilizing as fact that the intentionally sounded object is usually of smaller dimensions than the surfaces or volumes giving rise to such interference and that the smaller the object the more similar will be the echo to the transmitted sounding pulse. Thus by employing constant-amplitude frequency modulated pulses for the sounding pulses the greater degree of amplitude modulation imparted by reflection at the interference producing surfaces etc. than by the smaller intentionally sounded object results in the band-width of the reflected signal spectrum due to the latter being much smaller than that due to the reflections by the former so that filter 11 rejects most of the latter. An arrangement employing a second mixer and constant frequency source in the path 3 between the band-pass-filter 17 and mixer 4 is described with reference to Fig. 1 (not shown).

Title: Improvements in and relating to Electric Conductors suitable for Sealing into Vitreous Material.
IPC: C03C27/04
Filed: 1916-03-25
Abstract: 104,758. British Thomson - Houston Co., (General Electric Co.). March 25, 1916. Wire adapted to be sealed into glass or the like consists of a thin metal sleeve 2, Fig. 1, a metal core 3, and a thin intermediate layer 4 of refractory material, such as carbon, graphite, clay, plaster of paris, powdered cast iron, steel, or other metal not capable of cementing the sleeve and core, or an oxide such as silica, manganese dioxide, lime, or chromium oxide. The sleeve and core may have different meiting-points, and are preferably of metals or alloys easily soldered or welded; a brass tube may, for instance, be used with a copper core, or a copper tube with a brass core thinly coppered to prevent reaction with the intermediate layer. Both sleeve and core may be of copper. Platinum, nickel-iron alloy, or other metal having the same coefficient of expansion as glass, may also be used for the sleeve. Additional tubes and refractory layers may be interposed between the outer sleeve and core, or the core may be constituted by a series of such tubes and layers. If hollow, the core may be left empty or filled with metal. The sleeve, core, or both, may also be composed of co-axial tubes of the same or different metals without separating-layers; in some cases these tubes are welded together. In making a conductor with a simple sheath and core, a bar 12, Fig. 6, of the core metal, enveloped in paper, veneer, matchwood, &c., previously compressed by rolling, may be inserted in a square tube 11. The composite ingot is heated to char the intermediate layer, and is then rolled and drawn. Annealing may be effected in hydrogen. Specification 18685/14 is referred to.

Patent GB-610812-A (GB)
Title: Reclaiming rubber
IPC: C08J11/18
Filed: 1945-02-23
Abstract: Vulcanized natural and synthetic rubbers are reclaimed by heating them in the presence of available oxygen and terminating the treatment when an initial anomalous plasticity has been attained and before the point at which the plasticity again begins to increase in the normal slow manner.  Anomalous plasticity is defined as the very rapid initial increase in plasticity followed by a rapid decrease which take place before a further reversion occurs and the plasticity increases slowly in accordance with the previously known normal behaviour.  The process is effected by heating the rubber, preferably in an autoclave; by radiant energy, especially infra-red radiation; by steam; by direct heating or by alternating mechanical or electrical stresses; or by milling, masticating or on hot rolls, the rubber preferably being finely ground before treatment.  Temperatures between 220 DEG F. and 400 DEG F. are normally employed, oxygen being provided by means of air, peroxides or per salts.  The time varies from 2 minutes up to about 100 minutes.  The process is normally terminated before the reversion point but may be continued almost up to that point, the process then being terminated rapidly, e.g. by blowing the charge into cold water.  The reclaiming agents may be aromatic mercaptans such as xylyl mercaptan in kerosene, benzyl mercaptan, alpha-naphthyl mercaptan, thiophenols, aromatic sulphides such as phenyl sulphide, diphenyl sulphide, diphenyl disulphide, benzyl disulphide, aliphatic mercaptans such as amyl mercaptan, isoamyl mercaptan, butyl mercaptan, dodecyl mercaptan; aliphatic sulphides including diamyl sulphide, n. amyl disulphide, iso-amyl disulphide and n. butyl disulphide; unsaturated hydrocarbons including terpenes, such as terpinolene and dicyclopentadiene; unsaturated ketones including phorone; and nitrogen containing compounds including the condensation product of butyraldehyde and aniline, hydrazo benzene, azoxybenzene, azobenzene and pyrrole. Softening agents including pine tar, coal tar, fatty acids, coumarone indene resin, rosin or rosin oil, and solvents such as kerosene, xylol and small quantities of water may also be added. The synthetic rubbers which may be processed include neoprene and copolymers of butadiene with styrene and acrylonitrile but exclude factice and the polysulphide elastomers.  Specification 610,901 is referred to.

In the construction shown the envelope comprises an upper portion 1 of copper constituting the anode and a lower glass portion 2, and the cathode support wires 3 and grid support wires 4 are sealed into a moulded glass rod 5 of slightly wedge-shaped cross section. Each end of this rod is formed with a facing 6 adapted to abut against a corresponding facing 7 moulded in the glass portion 2.
