Filed: 1920-07-08
Abstract: 147,755. Ges. f³r Drahtlose Telegraphie. June 3. 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Addition to 145,629. Bearings, determining wirelessly; directive wireless signalling; aerials.-In the apparatus for determining the direction of electro-magnetic waves, comprising the small rotatable coil, tuned circuit, and amplifier-detector described in the parent Specification, the effect of the electric fieid on the coil is utilized to increase the amount of energy absorbed, and the resultant asymmetry is eliminated by means of a loose receiver coupling or by the use of a secondary circuit. The effect may be intensified by earthing one or both ends of the frame coil or one or both leads to the amplifier through condensers or high frequency resistances, or alternatively the ends of the coil or the leads to the amplifier may be connected together by condensers or resistances and the middle point earthed. In each case asymmetry is avoided by adjustment of the resistances or condensers. The customary ambiguity of 180 degrees can be eliminated by associating with the coil a metal screen, or tuned coil, or the like, which when disposed between the coil and the transmitting station renders the minimum indistinct, but when placed behind the coil has no appreciable influence. The screening system is preferably connected with the coil-rotating mechanism in such a manner that the pointer directly indicates the correct direction of the transmitting station.

Title: Improvements in or relating to filling vessels with gas
IPC: H01J9/40
Filed: 1946-07-04
Abstract: 679,111. Glass manufacture. PHILIPS LAMPS, Ltd. July 4, 1946 [April 16, 1942], No. 20015/46. Class 56. [Also in Groups XI and XL (a)] A method of filling a vessel 1 provided with a glass exhaust tube 3 with gas at a pressure exceeding that of the surrounding medium comprises four steps. First the vessel is filled with gas at the pressure of the surrounding medium and then exhaust tube 3 is heated until its inner surface becomes adhesive; this may be done by heating with gas jets 4. Then the outer surface of the tube is cooled, if necessary, by an air blast 7 until it is no longer plastic; finally the vessel is filled with gas at the operating pressure and the exhaust tube is pinched together by the tongs 5 so that the inner surfaces adhere. The tube may be drawn out slightly either before or during the pinching operation. The tongs 5 should be of material having low thermal conductivity such as chrome iron. An alternative method of heating uses a heating element inside the exhaust tube so that the inner surface alone is heated; the element may be heated by high frequency induction or by a resistance element and is normally removed before pinching, but if it is a metal rod heated by high frequency it may be left in position and sealed to the glass. Specification 406,185, [Group XI], is referred to.
