Granted: 1910-12-15
Abstract: 29,637. Belcourt, L. E., and Lebret, L. S. Dec. 18. Party-line systems and apparatus.-Each station on a party-line is provided with a contact arm H, which can be rotated step by step by alternate positive and negative currents in the line, and with keys L and batteries G<1> for producing such currents. The arms H are differently set at each station, and co-operate with mercury pools J to close a bell circuit at the selected station. The arms H act as pointers to indicate on dials at all stations the station at which a call is being made. Each contact arm H is mounted on an escapement wheel having twice as many. teeth as there are stations on the line, alternate teeth corresponding to positions in which all the contact arms are out of action. The escapement anchor is rocked by an armature mounted between two electro-magnets connected in parallel in the line, the magnet cores being oppositely polarized by permanent horseshoe magnets. Magnetos may be used instead of batteries. The mercury contact may be replaced by a device comprising two gear-wheels, one of which carries an insulated arm which makes contact with the other. The apparatus at each station may be enclosed in a glass case.

Title: Improvements in and relating to Devices for Detecting Combustible Gases.
Inventor: PHILIP ARNOLD
IPC: G01N27/16
Filed: 1910-03-01
Granted: 1911-04-03
Abstract: 5142. Philip, A., and Steele, L. J. March 1. Explosive gases, detecting. - Automatic means are provided for preventing overheating in explosive-gas detectors dependent on a catalytic substance. In the apparatus shown in Fig. 1, platinized asbestos or the like a, in a cylinder b, is heated by a current in a coil c, and causes the combustion of any explosive gas, the pressure of which is then indicated by the joining of contacts e by the rising of the mercury in a thermometer d, an electric circuit being closed thereby and an alarm operated. Overheating is prevented by an electro - magnet p in the alarm circuit attracting its armature and releasing a rotatable disk valve h, which is then closed by a spring m to cut off the supply of air under test. The valve h, in closing, may strike a stem q and operate a switch to break the circuit through the heating-coil c. In another form of apparatus in which two circuits in parallel, one of which contains an exposed catalytic wire, control short-circuits on two lamps, one of which forms the indicating-means, an electro-magnet 19, Fig. 4, in circuit with the indicating.-lamp, is excited when the lamp is lit. The cone 13 is thus raised, and, by means of a plate 16, closes the pipe 10 supplying the air under test, and opens a pipe 17 through which pure air or inert gas is supplied for cooling purposes. Provision may be made of a pipe 12 controlled by a conical valve 11 on the core 13 and opening into a pipe 18, by which the air under test is led away from the apparatus. When the core 13 is raised, air from the pipe 10 passes through the pipe 12, and by ejector action increases the draught of pure air. In a modification, the electro-magnet 19 controls a pivoted valve comprising a bent plate or the like, one part of which controls the pipe 10 and the other part controls the pipe 17. In a further modification, Fig. 7, a capsule 24 containing an easily-vaporized liquid acts through a lever 26 to move a valve 27 controlling the pipes 10, 17.

Abstract: 14,471. Venner, R. F., and Griesbach, R. C. Dec. 15. Electro-magnetic interrupters. - Automatic electric " limit " switches of the kind which act as continual interrupters as long as a predetermined load is exceeded, are constructed with an electro-magnet c, and two independently pivoted gravity levers b, g, one of which, carrying a U- shaped armature b*, when attracted by the electro-magnet, acts by impact on the other lever to break the circuit across mercury cups d. An arm g* attached to the lever g receives the impact. The movable armature and the fixed electro-magnet core are laminated to eliminate hysteresis effects, and the armature is arranged to pass across the face of the core without touching it. To give a dead-beat movement, a loose weight i with a large hole is hung over a pin at the end of the lever g. The lever b returns to an adjustable stop m. In a slightly modified form, the lever b is fitted with a striker arm.

Abstract: 4518. Heilmann, J. J. Feb. 22. Radial-flow type; working-fluid supply; reversing; regulating.-A drum having explosion chambers 8 rotates between a fixed inner drum, through ports 3 in which the explosion mixture is led, and an outer stationary casing 1 having pockets 10 which register with the chambers 8 at the time of the explosion and conduct the gases away to the exhaust. The ports 3 in the stationary drum are intermittently opened by means of an oscillatory or rotary tubular valve 13. Two sets of chambers 8 and pockets 10 oppositely arranged are provided, and the explosion mixture is admitted to one or the other as determined by a piston valve 21 which is moved longitudinally by a lever 28. Air is admitted through a central pipe 23 and ports 22. Pipes 25 open into the ports 22, and gas is drawn through them by the rush of air past their open ends. When the ports 22 open into one set of chambers 8, the other set communicates with the atmosphere through the open ends of the valve 13 and, acting as a pump. serve to reduce the back pressure at the exhaust of the working set. The sparking-plugs 30 are connected to a magneto machine 17 driven by gearing 31, 32, 33, 35 from the main shaft.

Retort furnaces.-In a process of surface combustion such as that described in Specifications 25,808/09, [Class 51 (i), Furnaces &c., Combustion apparatus &c.], and 29,430/09, the supporter of combustion, such as air, or the fuel, such as gas, or both, are heated before being mixed and burned. The Figure shows a retort 4 heated by a gas and air mixture burning in a bed 5 of granular refractory material surrounding it. The combustion products on their way to the outlet 13 pass through a similar bed surrounding a fire-clay, plumbago, or like tube or tubes 6 through which the air is forced. Gas is supplied by a pipe 10, and is admitted to the mixing-conduit 9 by a number of small holes. The cross-section of the conduit 9 is small enough to cause the gases to flow at a high speed and prevent any considerable combustion from taking place inside it. The conduit 9 is made by placing iron rods centrally in iron tubes 7, 11, ramming refractory material into them, withdrawing the rods, and baking the refractory material. The fuel may be similarly heated.
