Abstract: 1,178,051. Cathode materials and processing. MATSUSHITA ELECTRONICS CORP. 12 April, 1967 [20 April, 1966], No. 16717/57. Heading H1D. A discharge tube, more especially a lowpressure Hg fluorescent lamp, has cathodes coated with emissive material comprising the oxides of Ba, Sr and Ca together with, in a proportion of from 0À5-10% by weight of the oxides, a substance having the composition: { ( 1-x-y)Fe : xCo : 0À5yMe} 2  B Z  where 0À15 # x #0À6; 0À01 # y # 0À3; 1#z# 1À15 and wherein Me is one or more of the metals selected from the group consisting of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Al and Si, and the mixture of oxides and the borides further containing, in a proportion of from 1-8% by weight of the oxides, one or more high melting point reducing metals selected from group comprising Zr, Hf, Nb and Ta. Initially, with the oxides present as carbonates, the emissive mixture may be suspended in a butyl acetate solution of nitrocellulose and applied to double or triple W coil supports, and the resulting coated coils may subsequently be heated during the degassing of the tube to convert the carbonates to oxides. The substitution of the metals Me in the iron boride helps prevent the oxidation of the borides during the heating and degassing process. Fluorescent lamps incorporating such cathodes reduce interfering noise to 15dB or less and the blackening of the lamp envelope is held at an acceptable level. A number of specific examples of the composition of the emissive material are given.

Filed: 1932-06-16
Abstract: 386,544. Thermostats. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Vapor Car Heating Co., Inc. ; 80, East Jackson Boulevard, Chicago, U.S.A.) June 16, 1932, No. 17098. [Class 135.] In a device for regulating the steam supply to the heating system of a railway vehicle by means of a thermostat in the outlet from the radiators, a casting 1 is provided with a steamreducing valve 12 and a thermostat assembly 6. The valve rod 13 is connected by a bell-crank lever 17 to the operating rod 22 which rests on a thermostatic capsule 35. Condensate from the heating system is led into the chamber 25 and passes mainly into the space 28 while the exhaust steam or hot gas passes mainly into the inner tube 27. The thermostat capsule 35 contains volatile liquid and is adjusted by a screw 37, so that if steam reaches the capsule, expansion takes place and the valve 12 is prevented from opening under steam pressure. The steam supply pressure in the chamber 3 may vary while the steam pressure in the chamber 4 is substantially atmospheric, and means are provided whereby the variable pressure tending to open the valve is in part balanced: A chamber 43 in communication with the steam supply contains a flexible bellows 52, the central rod 55 of which is connected by a yoke 53 to the pivot 21 carried by rod 22, so that the steam pressure acting on the bellows tends to close the valve 12, and the resultant force to be overcome by the capsule 35 is small. A modified construction, Figs. 6, 7, and 8 (not shown), is described in which the chamber 43 is arranged at right-angles to the axis of the thermostat, the connection being through a bell-crank lever.

Title: Improvements in or relating to the preparation of single crystals from the vapour phase
IPC: C01B21/072
Filed: 1959-05-20
Abstract: Single crystals of a compound are produced on the inside walls of a porous container by packing the compound or the constituents thereof around the container and heating the packed material under such conditions that a supersaturated vapour of the compound is first formed in the container so as to produce nucleation of single crystals and the degree of supersaturation is thereafter lowered below the nucleation pressure so as to cause growth of the nucleated crystals.  The compound may be silicon carbide, boron nitride, boron phosphide, or gallium phosphide.  The porous container may be of graphite, silicon carbide, or silica.  The container may be in the form of a hollow cylinder closed at each end by a disc.  The walls of the cylinder may be thinner at certain points or may be perforated. In the production of silicon carbide, areas of silicon may be dabbed on the inside surface of the cylinder.  The packed material may be contained in a carbon crucible which is surrounded by a resistance heating element in the form of an internally lined carbon tube slotted along most of its length.  The carbon crucible may be contained in an apparatus which may be evacuated to a pressure of 10-6mm. of Hg.  The components of the apparatus may be baked at 2700 DEG C. in an argon-chlorine atmosphere.  Crystallization may be effected in the presence of argon which may contain a doping agent. An example specifying temperatures and rate of heating is given. P- and N-type silicon carbide crystals may be produced having a resistivity of 5 X 106 ohm-cm. and 1 X 106 ohm-cm. respectively.
