Filed: 1921-01-10
Abstract: 157,802. Florell, Y. March 8, 1919, [Convention date]. Ball, roller, and cylindrical journal bearings.-In a bearing in which a ball or roller bearing and a friction bearing are mounted one upon the other, the friction bearing sleeve projects laterally beyond the race ring mounted thereon, and the projecting parts and the casing of the antifriction bearings are arranged so that normally they do not engage each other, but, upon a small movement towards each other, come into engagement and are locked together, so that the antifriction bearing is put out of action, and the friction bearing comes into operation. In a wagon axle-box, a shaft 1 carries a sleeve bearing 3 with Babbitt-metal lining 2. The sleeve, is divided, and has a conical outer surface carrying the inner race-ring of the antifriction bearing, which is clamped in position 'by a sleeve 5 and screw 6. The conical surface may be replaced by a shoulder. The antifriction bearing is carried in a casing 7, packing 8, 9 being arranged between the box and the sleeve 3. The casing 7 rests on the antifriction bearing through a layer 10 of an elastic, fusible material such as rubber. When the antifriction bearing runs hot, the layer 10 melts and the sides of the casing 7 move into engagement with the sleeve 3 and are locked thereto. The sleeve 3 is provided with chambers containing lubricant communication with the friction surface.

Title: A mobile apparatus for a radiomobile telecommunications system integrated with the public telephone network
IPC: H04W48/16
Filed: 1971-01-13
Abstract: 1,268,030. Automatic exchange systems. SOC. ITALIANA TELECOMUNICAZIONI SIEMENS S.p.A. 13 Jan., 1971 [4 Feb., 1970], No. 1598/71. Heading H4K. In a system having mobile subscribers connected via radio channels to the public telephone network, each subscriber set includes a coding matrix whose columns are sequentially read-out automatically so as to cause a two-out-of-six tone generator to transmit the set's identity whenever the set goes off-hook at the beginning of a call or whenever its call detector responds to an incoming calling signal at the beginning of a call. A wanted subscriber's number is setup, prior to going off-hook, on another matrix whose columns are read-out in a similar way after the set identity code has been sent. If two or four or six &c. successive digits are the same, a special repetition code is transmitted instead of the normal digit code for the second, fourth &c. digit, a set of comparator gates being provided for this purpose. A number may comprise up to ten digits. All numbers (wanted or own) are prefixed and suffixed by respectively " start message " and " end message " two-tone codes. The two-out-of-six generator comprises two frequency selective circuits which are energized by weighted 2-out-of-6 codes derived from the markings in the matrix columns. A single channel is used for signalling to and from the mobiles. Each mobile's speech transceiver normally rests on the channel to which it was tuned during the last call so that this channel becomes first choice on subsequent calls. If a " channel occupied " signal, e.g. the carrier, ceases, e.g. due to fading, during a call, the set is cleared down after a predetermined time. It is also cleared, if a free channel cannot be found, on hanging up the telephone instrument and on receipt of an " end-call " signal from the exchange. Detailed logic circuitry for performing all the functions mentioned above is given in the Specification.

Filed: 1938-01-19
Abstract: 509,702. Artificial filaments, ribbons &c. I.G. FARBENINDUSTRIE AKT.-GES. Jan. 19, 1938, No. 1772. Convention date, Jan. 19, 1937. [Class 2 (ii)] Filaments, threads, filaments, bands &c. are made from cellulose acetate soluble in chloroform by spinning a crude acetic acid solution of the cellulose acetate at an elevated temperature into an aqueous inorganic salt solution at a lower temperature. The crude cellulose acetate solution may be those produced by the usual acetylation processes, preferably those employing only small amounts of catalyst, e.g., sulphuric acid as described in Specification 337,366, [Class 2 (ii)]. The acetic acid content of the cellulose acetate may vary between 59-62.5 per cent. and is preferably between 60-61.5 per cent., the cellulose acetate as first obtained being subjected to a slight hydrolysis. Before spinning the acetylation catalyst is neutralized and the crude cellulose acetate solution is brought to a suitable cellulose acetate content-preferably 12-16 per cent. ; it is stated that a small content 2-6 per cent. of methylene chloride and water has a beneficial effect in the spinning process. The cellulose acetate spinning solution is then heated to 50-90‹C. depending on the viscosity of the solution, the higher viscosities necessitating higher temperatures. The coagulating bath may consist of solutions of sodium sulphate, sodium chloride, sodium acetate, calcium chloride, and ammonium salts such as the chloride, sulphate or acetate ; the concentration may be 10-30 per cent. and the temperature below about 30 ‹C. The coagulating liquid is preferably caused to act on the precipitated filaments in counter current, the quantity and velocity thereof being so chosen that the acetic acid content of the precipitating liquid increases up to 15-30 per cent. Specifications 341,148 and 418,480 also are referred to.

Abstract: 796,968. Gas burners. CARRIER ENGINEERING CO., Ltd. Jan. 19. 1956 [Sept. 1, 1955], No. 1910/56. Class 75(1) An atmospheric gas burner comprises a veturi shaped mixing chamber having a gas inlet surrounded by a primary airintake and shaped so that primary air induced into the mixing chamber by the venturi action of the gas flowing into the chamber forms in the mixing chamber a primary air-gas mixture containing insufficient air for optimum combustion, the mixing chamber leading to an annular slot orifice surrounding a secondary air intake so that the primary air-gas mixture discharged from the slot induces secondary air through the secondary air intake and mixed therewith in front of the slot to form a gas-air mixture having sufficient air for optimum combustion, there being an igniter device adjacent the slot orifice to ignite the mixture in front of the slot orifice and a target disposed in front of the slot orifice on to which the ignited mixture impinges. Gas flows through a cock 17 to a pressure regulator 16 and then a solenoid valve 15 to issue through a gas spud 13 to draw about 45 per cent or less of its total air requirements through the open end 29 of a venturi 28. An adjustable screw 27 or any suitable type of shutter arranged at the throat 31. of the venturi 28 determines the amount of air induced into the venturi 28. The gas and air mixture passes downwardly through the venturi 28, to an annular chamber 32 and then horizontally through an annular orifice 33 having a width of from 1/8 to 1/4 of an inch into the combustion zone. Secondary air is supplied to the combustion zone through a circular bore 34 of a pipe 35 and passes through the space between the peripheral edge of a baffle 39 and the pipe interior. The gas and air mixture and the secondary air impinge on a disc 42, supported from the baffle 39 by a rod 41, to effect mixing of the two fluid streams. The upper part of the baffle 39 is angularly disposed and supports a pilot burner 43 and a thermal element 44 such as a thermocouple or thermally responsive bulb. The thermal element is connected to the solenoid valve 15 by a line 18 and closes the valve 15 if the element temperature falls below a predetermined value. The pilot burner 43 is fed through a pipe 19 and valve 20. Two radiation plates 23, 24 are provided behind the burner mounting plate 9. Surrounding the open end of the burner within the fire box is a shield 25 to prevent oxidized gases returning to the flame region. The burner is constructed throughout of sheet metal.
