Abstract: 275,386. Shaw, H., and Jones, E. Lancaster-. July 2, 1926. Gravity, measuring force of. - In a torsion balance for determining gravitational constants the suspended mass system or beam is so arranged that the difference between its moments of inertia about two coplanar horizontal axes fixed at right-angles to each other in the system is zero or negligibly small. In particular, arrangements are described in which the moment of inertia of the system about a horizontal line intersecting the vertical line through the centre of gravity is the same for all such horizontal lines in any one horizontal plane.-Various possible forms of the system are described, examples being shown in Figs. 2 and 6. In Fig. 2 the projection of the system on a horizontal plane comprises a uniform ring bounded by concentric circles, and in Fig. 6 it comprises a number of equal masses set at the vertices of a regular polygon. The elements of the system may lie in the same or in different horizontal planes. Two or more systems of the above kind may be employed together, the systems being oriented at any desired angle in relation to each other. For example, there may be two systems set at 90‹ to each other, or three set at 120‹ to each other. The two or more systems may be rotatable about a common axis or about separate axes.

Abstract: 403,639. Filters. SHANNON, D. M., 44, Longridge Road, Earl's Court, London. June 14, 1932, No. 16738. [Class 46.] A filter for separating solid impurities from oil &c. comprises a jacketed casing having ports 3, 4 for the inlet and outlet of a heating or cooling medium and containing a plug 7 having ribs 8b, Fig. 2, forming longitudinal channels 8 on its outer surface. The plug is adapted to be reciprocated by hand against the pressure of a spring 15, which may however be placed outside the casing as shown in dotted lines, by a hollow rod 16. The oil enters the casing by a port 5 and flows through the rod to radial passages 20 by which it is distributed to alternate channels from which it passes over the edges of the ribs, which are in close proximity to the inside of the casing, into the adjacent channels and thence through the annular passage between the rod and the spigot 21 on the casing cover to the outlet 6. The impurities in the oil collect in the channels and are periodically forced into the sump 9 by reciprocating the plug so as to shut off the outlet 6 from the interior of the casing and reverse the oil flow in the channels. In the event of the channels becoming choked the oil passes through the ball valve 14 directly to the outlet 6. The channels may be tapered. In a modification, a duplex apparatus is described.

Title: Improvements in and relating to electric incandescent arc devices
IPC: H01J61/86
Filed: 1922-06-17
Abstract: 191,337. British Thomson - Houston Co., Ltd., (General Electric Co.). June 17, 1922. Arc lamps; arc-lamp electrodes.-In an are lamp having a container in which the electrodes are arranged in a gaseous atmosphere, the arc is prevented from playing between the leading-in wires by associating with the leading-in wire adjacent to the cathode a material having a higher electron emissivity than the rest of the conductor. The electrodes 1, 2 are substantially equal in size and are formed of a refractory metal such as tungsten; they normally operate at bright incandescence. The parts 6, 7, Fig. 1, of the leading-in wires 3, 4, which may also be of tungsten, are bent inwards so that the gap between the electrodes is less than that between the leading-in wires. Beads 14, 15 of thorium, an alloy of thorium, thoriated tungsten, cr other material of high electron emissivity, are arranged at the ends of the straight portions 6, 7 of the leading-in wires, or these portions may be formed of thoriated tungsten wire. A suitable composition is tungsten containing 5 per cent of thoria. The bulb 5 contains argon, nitrogen, or other inert gas and a quantity of mercury 8. A condensing-cham'ber 11 is arranged with a constricted orifice 12 in line with the blast of mercury vapour from the electrodes 1, 2, and serves to determine the vapour pressure about the electrodes. In a modification the leading-in wires project downwardly from the top of the condensing chamber. The arc may be started by a high-potential discharge or, as shown in Fig. 3, by arranging auxiliary conductors 20, 21 below the electrodes so as to dip into mercury 8 which communicates with an auxiliary chamber 23 containing gas at the same pressure as that in the main bulb. The conductors 20, 21 become heated and ionize the gas between the electrodes 1, 2, thereby starting the arc; the resulting increase of vapour pressure in the bulb 5 lowers the level of the mercury 8 and breaks the circuit through the conductors 20, 21. In a modification, contact between the conductors 20, 21 and the mercury is effected by tilting the bulb, the chamber 23 being dispensed with. Auxiliary arcs are formed which lengthen and break on restoring the bulb to the vertical, at the same time ionizing the space between the electrodes 1, 2.
