Abstract: 310,810. Spanner, H. J., and D÷ring, U. April 30, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Vacuum tubes; low-pressure metallic-vapour apparatus.-A discharge tube containing gases or a mixture of gases and metallic vapours has a hot cathode for maintaining the discharge; the electrodes consist preferably of mixtures or compounds of substances having high electron emissivity, such as caesium, rubidium or barium or their compounds, with amphoteric substances, which, while behaving as anions towards caesium oxide and similar strong bases, possess b,asic characteristics. The amphoteric substances may be oxides of aluminium, zirconium, nickel, iron, cobalt or chromium, which unite with the electron-emitting material to form aluminates, nickelates etc.; or compounds such as hydrides, nitrides, cyanides, or oxides, which decompose by heating and free the metal, may be used. Such an electrode used as a cathode offers high resistance to ionic bombardment and is not liable to disintegration. The electron-emitting material may be a coating on a carrier of metal such as tungsten or molybdenum, whose oxide behaves amphoterically; the surface of the carrier may be oxidized beforehand, or an intermediate layer of such amphoteric compounds may be formed. A lamp with a filling of rare gases or a mixture of rare gases and metallic vapours may be run direct from the supply mains; or a filling of hydrogen or carbon dioxide may be used. The cathode may be heated directly, for example, by connecting a coiled electrode with a transformer, or indirectly by a heating member transmitting heat to a surface coated with electron-emitting material. The envelope may be permeable to ultra-violet rays. and if desired, also to visible rays. A sheath or screen of coloured or fluorescent material such as lead glass, or glass containing scandium, mav be used, or the screen may have a coating of fluorescent material.

Title: Improvements relating to entrenching ploughs
IPC: A01B13/00
Filed: 1942-09-29
Abstract: 559,901. Cable-laying ploughs. FRASER & FRASER, Ltd., and ANGUS, A. R. Sept. 29, 1942, No. 13668. [Class 6 (i)] Ploughs for entrenching cables, placing concrete foundation layers, or cutting mole-drains comprise a frame consisting of horizontal runners 1 connected by vertical struts 3, 4 to inclined beams 2. Pivoted to an axle 7 extending through the uprights 4 is a lever or mast 8 and anglebrackets 9 carrying ground wheels 16. A cross-rod 17 fixes the brackets relatively to the frame members 1. A coulter 21 is guided between cheeks 20 secured to the frame and is fixable in different positions by cross-rods inserted in holes in the coulter and cheeks. The coulter is formed with a forwardly-extending horizontal root-cutting upper part and a renewable nose 23. A cable guide 25 is fitted to its rear edge. Slotted segments 10 are secured to the frame members 2 enabling the mast 8 to be retained in required adjusted position. Its upper end has mounted thereon a cable guide 12 and a pulley 13 over which runs a rope 14 from a hand-winch 15. From the road transport position with the wheels on the ground, the procedure consists in upwardly tilting the mast, securing one end of the rope 14 to the coulter, removing one of the rods 30, 31, and lowering the coulter into a prepared starting hole in the ground. The coulter having been secured by replacement of the rod, the mast is forwardly tilted, and the end of the rope connected to a point near the winch 15 which is then unwound after the pin 17 has been removed. The frame is thus lowered to ground level and the wheels relatively lifted. A stand 32 enables an operator to feed the cable over the guide 12 from a drum in advance of the apparatus. For laying moledrains or concrete foundations a coulter associated with a hopper or magazine may be substituted for that having a cable-guide.

Title: Improvements in frequency or phase modulation receivers
IPC: H03G3/28
Filed: 1941-10-24
Abstract: 552,462. Frequency and phase modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 24, 1941, No. 13717. Convention date, Oct. 25, 1940. [Class 40 (v)] A frequency or phase modulation receiver is muted unless the receiver is accurately tuned to an incoming signal. The intermediate frequency is applied by tuned circuits 1, 2 to a limiter valve 3 which feeds a frequencydiscriminating detector network. This may be of the off-tune type as shown, or of the phasing type described in Specification 489,094. The demodulated output is taken across rectifier load resistances 9, 11 through a smoothing circuit 26 to a relay oil 22, so that while the tuning is inaccurate a direct current passes through the coil 22, attracts the armature 20 against the action of a spring 30, and holds open the contacts 40 so as to cut off the detector from the audio-frequency input line 50. Only when the tuning is accurate does the direct current fall to zero and allow the signal to pass to the audio-frequency circuits. Closure of the contacts 40 is assisted by a coil 21 which is connected to a condenser-shunted leak 4 in the grid circuit of the valve 3 and which receives maximum current when the set is accurately tuned. The coils 21, 22 may be connected as series coils instead of shunt coils, and the contact 40 may be across the audio-frequency input. The relay may operate by biasing an audio-frequency amplifier. The Specification as open to inspection under Sect. 91 refers to an electronic relay arrangement used in place of the electro-mechanical relay. This subject-matter does not appear in the Specification as accepted.
