Title: Process for the production of high filling gas pressures in electric incandescent lamps and discharge lamps
IPC: H01J9/395
Filed: 1938-03-22
Abstract: 502,769. Discharge lamps. VEREINIGTE GLUHLAMPEN UND ELEKTRIZITATS AKT.-GES. March 22,1938, No. 8761. Convention date, March 22, 1937. [Class 39 (i)] [Also in Group XI] In a process for the production of a filling gas pressure exceeding one atmosphere and preferably exceeding five atmospheres at room temperature in electric incandescent lamps or discharge lamps, a definite quantity of a gas or a mixture of gases is introduced into a lamp bulb by : Pumping out the bulb, cooling it down to a temperature low enough to cause the gas or gas mixture to become wholly or partially con. densed to a solid or liquid state within the bulb, sealing off the bulb, and allowing it to return to room temperature, the total pressure in the bulb at the time of sealing off amounting to less than eight atmospheres, preferably less than one atmosphere. In an example wherein leading-in wires to a filament extend through each end of a tubular quartz bulb, one end is sealed off and the other end is connected to the pump through a hollow ball of known capacity. The lamp bulb and the ball are next filled with krypton, for example at a pressure of 650 mm. of mercury, and sealed off from the pump, after which the bulb is immersed in liquid air and cooled down, whereby practically the whole of the krypton is condensed to a solid state within the lamp bulb. The end of the bulb connected to the ball is then sealed off and the leading-in conductor at that end sealed within it. In a further example wherein a high pressure lamp is to be filled with argon, the amount of argon is calculated by admitting it through a throttle valve at known velocity. Reference has been directed by the Comptroller to Specification 473,863.

Title: Improvements in or relating to heating systems for the bodies of self-propelled vehicles
IPC: B60S1/02
Filed: 1948-03-27
Abstract: 654,768. Heating vehicles; tubular heat exchangers. BETTNEY, T. M. March 27, 1948, Nos. 8917, 15223 and 29860. [Classes 64(ii) and 64(iii)] [Also in Group X] Relates to heating systems, incorporating apparatus such as interior or exterior de-misters and de-frosters 55 (see Group X) and internal heating radiators 56, for use in vehicles propelled by internal combustion engines which have a radiator 50 for cooling the engine cool- .ant. According to the invention, only liquid which is displaced from the radiator 50 due to thermal expansion of the bulk of the liquid is supplied by a pipe 73, which may be the normal radiator overflow pipe, from a high level in the radiator to a boiler 52 in contact with the exhaust system, hot liquid and vapour passing through a pipe 54 to the heating apparatus 55, 56. Moreover, an expansion tank 76 below the floor boards receives the excess liquid and condensate. The inlet pipe 75 to the expansion tank is connected to the inlet side of a non-return valve 74 the outlet side of which connects to the inlet side of a second non-return valve 70 in the boiler inlet pipe. A pipe 77 provides communication from a point between the second valve 70 and the boiler to the open top of the expansion tank by way of the non-return valve 74. The relief spring-loading may be varied by a hand wheel 38 at the dashboard. When the cooling system temperature drops, liquid is drawn back into the engine radiator 50 by way of the non-return valve, 74. The relief valve 78 prevents the building up of excessive pressure in the boiler inlet and by removing the spring-loading from the valve 78 the system may be put out of action. In one form of the system, Fig. 2, in which the expansion tank is at a higher level, two pipes 32, 33, equivalent to the pipes 75, 77 communicating with the expansion tank, communicate directly with the housing of a non-return flap valve 30 whilst the other non-return valve 70 is omitted. In another form, the return from the valve 74 communicates with the bottom of the engine radiator and not, as shown, with the boiler inlet pipe 73. A boiler section, for inclusion in the vehicle exhaust pipe 11, Fig. 2, consists of an exhaust pipe section 17 having openings 15, 16 through which exhaust gases pass into and out of a casing 13 surrounding the liquid pipe 14 coiled around the pipe 17. The third Provisional Specification describes also a liquid pipe coiled within the exhaust pipe. According to the first Provisional Specification, water from the radiator to the heating system may pass directly to a section of the de-mister before entering the exhaust boiler.

Filed: 1915-08-06
Abstract: 125,417. Vickers, Ltd., and North, T. K. Aug. 6, 1915. Mines, marine. - Relates to submarine mines provided with an anchor adapted to anchor the mine automatically at a given depth. According to the invention, the anchor cable is wound on a fixed drum in the anchor, and during its paying out it displaces a device which stops further paying out when the predetermined length has been paid out. In the form shown, the cable B<1> is wound on a drum F fixed axially in the anchor B, and passes thence through a hole at the end of an arm F<2>, then over a roller g<1> at the end of a link G to the shackle C<2x> of the mine A, a spring being inserted as usual in the cable before it joins the shackle. The link G is pivoted at g to the arm F<2>, and is normally folded against it and into a slot f<xx> in the drum, being held in that position by a pin g<0> or by a spring. When the mine is laid, the tension in the anchor cable shears the pin g‹ and causes the link G to swing up about the pivot g until the roller g<1> lies in line with the axis of the drum F, stops f<2>x preventing further movement. The arm F<2> is carried by a screw-threaded shaft F' which is rotated with the arm F<2> by the cable B<1> as this is paid out, until a nut on the shaft abuts against the drum F. The nut can be adjusted along the shaft and is locked in the adjusted position by a spring pawl f, which is carried by the nut and snaps into one or other of two longitudinal slots in the shaft. This adjustment is performed by a key which, when applied to the nut, removes the pawl, from its locking position, and which is provided with a scale read against a fixed mark on the anchor to indicate the depth in fathoms for which the nut is set. The mine shown is of the kind described in Specification 11393/15.
