Title: Improvements in or relating to radio and other modulated carrier wave transmitters
IPC: H03C3/26
Filed: 1934-05-16
Abstract: 420,574. Wireless transmitting systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Usselman, G. L. ; Port Jefferson, Long Island, New York, U.S.A.) May 16, 1934, No. 14814. Convention date, May 17, 1933. [Class 40 (v)] Phase-modulating systems of the kind described in Specifications 411,638 and 411,643 are modified by employing a long-line as a resonant grid circuit for a self-oscillating valve pair. As shown, the long line A is sustained in oscillation by the back-coupling afforded by the line 14 adjustably coupled to the anode oscillatory circuit B. The leads from the line A to the valve grids include respectively a phase-retarding inductance L and a phaseadvancing capacity M, the anodes being connected to opposite ends of the tank circuit B. Signals from a source F are applied through a transformer T in push-pull relation to the two grids. The valves are set into oscillation by closing a key K, which can be used for telegraphy if a tone generator is used as the source F. Instead of using the magnetic back coupling, the line A can be excited by arranging the neutralizing condensers N1, N2 to be out of balance with the internal valve capacities. The line A should be an odd number of quarterwave-lengths long, and it may be earthed at its bridging point through a block condenser, and an inductance shunted by a resistance. Modulating voltages may be applied to the anodes, or to screen-grids if such are used.

Abstract: 528,986. Unwinding and straightening. BRENNEISEN, H. May 18, 1939, No. 14883. Convention date, May 19, 1938. [Class 83 (iv)] Wire, particularly that for binding packing cases, is straightened as it is drawn from the reel. The reel is mounted in notches in side plates 9 on a wheeled frame 3, and has radial wings 15 with notches 16 that prevent the wire from jamming. The wire is led off through an eye 28 on a cross bar 19and over a roller 24 journalled in arms 18, through an eye 26 and under a sleeve 8 mounted in arms 6 that serves also as a handle for moving the device. The eye 26 is on a frame pivoted about the axis of the roller 24 and provided with an arm 27 that contacts the bar 19 and prevents the frame from making a complete rotation. The arms 18 are pivoted at 17 eccentric to the axis of the reel and when the wire ceases to be drawn off, a spring 20 rocks the arms to the full line position in which the bar 19 acts as a brake on the flanges of the reel. Stops 21, 22 limit the amount of swing of the arms. If it is desired that the wire should retain a slight tendency to coil it is passed above the sleeve 8 instead of below it as shown. In a modification the sleeve is replaced by three straightening rolls, the amount of deflection imparted by the centre roll being adjustable.

Title: Improvements in lubricant-dispensing devices
IPC: F16N3/12
Filed: 1924-06-19
Abstract: 218,640. Allyne-Zerk Co., (Assignees of Zerk, O. U.). July 5, 1923, [Convention date]. Single-acting, suction-valveless piston pumps; suction reservoir.-A gun for supplying lubricant to a nipple comprises a container 61 with a piston 70 therein adapted to ensure feed of lubricant therefrom to a high-pressure cylinder 83, a high-pressure plunger 96 adapted to expel the contents of the cylinder 83 by force exerted between the container and the nipple, such force also effecting and maintaining a fluid-tight joint between the nozzle of the gun and the nipple, and means for preventing the entry of air into the cylinder 83. The cork piston 70, a cup-leather 71, and metal washers 72, 73, are secured together by a hollow rivet 74. A rod 113, having a reduced end 114, is screwed into one end of a cylindrical member 116 slidable in the rivet 74 under the control of a spring 120 bearing against the washer 73 and held in position on the member 116 by a nut 119. When the rod 113, which passes through a cap 64 and indicates the amount of lubricant in the container, is operated to withdraw the piston, the member 116 first slides in the rivet 74 and opens communication between the two sides of the piston through ports 118. The cap 64 is secured by a wire 67 sprung over a bead 68 and has air holes 55. The cylinder 83 is provided with a non-return valve 86 and is fitted with a nozzle 84 having a semi-spherical recess 91 adapted to make leak-proof contact with a nipple at various angles. The cylinder is slidable in a bore in a member 78 screwed to the head 75 of the container. A cylindrical member 98 having a longitudinal slot is screwed into the member 78 and has a flange 101 forming a seat for the head 103 of the plunger 96 which extends into the cylinder. A spring 106 is disposed between the head 103 and a shoulder 95 on the cylinder, which communicates with the container through a port 93. Packing 80, 108, 122 is arranged as shown. In operation, the nozzle 84 is pressed against a nipple by pressure on the handle 62 of the container, and, as the member 78 slides over the cylinder, the plunger 96 ejects the charge of lubricant from the cylinder under high pressure. On releasing the pressure, the cylinder returns to its normal position under the influence of the spring 106 and a vacuum is formed therein, whereby a new charge is drawn into the cylinder, the piston 70 being moved inwards by atmospheric pressure. When the container has been depleted of lubricant to a predetermined extent, the end 114 of the rod 113 depresses the plunger 96 and closes the port 93, as shown, thus preventing the recharging of the cylinder, and preventing the entry of air therein. The member 78 and the parts attached thereto are removable as a unit, and the head 75 may then be connected to a pressure tank for recharging the container. A nozzle such as 130, Fig. 4, may be screwed on to the head 75 for supplying lubricant at low pressure to gear cases &c., the lubricant being ejected by depressing the rod 113.

Title: Improvements in or relating to kilns of the tunnel type
IPC: F27B9/36
Filed: 1927-06-07
Abstract: 272,238. Compagnie GÚnÚrale de Construction de Fours. June 5, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Tunnel kilns.-In a tunnel kiln, which is so constructed that the temperature, and the atmosphere prevailing at various points of the tunnel can be controlled, the air supply for the fuel burners is heated in flues in the walls of the cooling- zone. In the kiln shown in sectional plan in Figs. 2 and 4 (which should be joined) air is supplied under pressure through ports 6, 7, the former opening into the tunnel and the latter into the flues 10 in the walls of the cooling-zone. By drawing off heated air through roof ports 8 the temperature gradient in the cooling-zone can be varied as desired. The air from the flues 10 is passed under control of a damper to flues 13, Fig. 6 running the length of the firing-zone, and from these through damper-controlled ports 15 to the burner ports 16. Gas is similarly supplied from longitudinal flues 20. In each burner port 16 the gas and air ports are separated by a tapering tongue 17. Solid fuel may be used in addition to gas, and in this case, and also when the materials under treatment give off combustible gases air alone may be supplied through some of the burner ports, or from other sources, e.g. through ports in the trucks. The waste gases are drawn off though flues 23 distributed along the preheating-zone, and by varying the proportion of gases drawn off at the different exits the temperature gradient may be varied. The goods to be fired are either built up directly on the trucks or placed in large saggers, which may have air ducts in their walls.
