Title: Oil burner
IPC: F23C99/00
Filed: 1930-09-24
Abstract: 361,051. Vapour burners. HEINEKE, H. B., 42, H. C. Orstedsvej, NIELSEN, A. and AKTIESELSKABET A. NIELSEN, 39, Amagerbrogade, both in Copenhagen. Sept. 24, 1930, No. 28589. [Class 75 (i).] Atmospheric vapour burners ; vaporizing apparatus; liquid fuel supply.-Liquid fuel vaporized in an annular chamber 12 formed with a transverse partition 13 issues through a channel 14 into a current of air supplied by a fan through a pipe 19 and then passes through a mixing channel 15 around the vaporizing chamber 12 until the mixture reaches a partition 16, when it ascends. through an aperture 17 into a mixing chamber 18. Part of the mixture is directed by a pivoted adjustable shield 59 in the mixing chamber to an aperture 36 in a pipe 34 by which the chambers 12, 18 and a cover 25 are secured together and is conducted to the bottom of the pipe where it burns at apertures surrounded by gauze 39 to heat the vaporizing chamber which is formed with radial ribs 43. The remainder of the mixture issues into the.stove or furnace through a neck 27 containing vertical and horizontal walls 32 faced with wire gauze 31 which is held in position by the mixing chamber being bolted to a plate 50 having a flange 51 lined with refractory blocks 52 inserted in the fire-door opening. The fuel supply to the vaporizing chamber and the air supply to the mixing chamber are regulated by valves 10, 20 having interconnected spindles simultaneously..adjustable ;by a handle 21. The liquid fuel in the supply tank 7 is maintained at a constant level by a pipe 56 fitted with a float valve and is subjected to the air pressure in the pipe 19 conveyed through a pipe 23 having an orifice 24 directed towards the air current. Vaporization is started by burning benzene in a receptacle 44 suspended by a perforated shield 41 from the chamber 12. The benzene is supplied through a receptacle 45 and combustion is accelerated by air supplied .from the pipe 19 through a pipe 47. When the benzene is burnt solar oil may be supplied through the receptacle 45.

Title: Improvements in or relating to thermionic valve transmitters for wireless signalling
IPC: H04L27/04
Filed: 1921-10-28
Abstract: 187,457. Hamilton, B. H. N. H. Oct. 28, 1921. Thermionic oscillation generators and modulating systems; keying systems. -Valve transmitters are controlled by a keying-device which in the sending-position simultaneously shortcircuits an impedance in the plate oscillatory circuit and a resistance in the plate supply circuit. In a modification, the keying-device shortcircuits the grid coupling coil during " spaces." Fig. 1 shows the former arrangement and Fig. 6 the latter. Referring to Fig. 1, the valve 6 is direct-coupled to the aerial and its plate-filament circuit is supplied with rectified current from a transformer 7 through rectifying-valves 8. A resistance 16 is connected in the plate supply circuit, and an impedance 14 in the plate oscillatory circuit, and separate short-circuiting switches 17, 15 are jointly controlled by the sending-key. When the impedance 14 is in circuit, the valve practically ceases to oscillate, and the plate voltage is simultaneously reduced by the insertion of the resistance 16. Two oscillating valves may have their plates connected to opposite ends of the transformer 7, the mid-point of which is connected through the resistance 16 to the filaments, thus eliminating the rectifying- valves 8. In another modification, the plate supply circuit and the plate oscillatory circuit are combined in a single circuit, in which the resistance 16 and impedance 14 are in series, both being short-circuited by a single switch. Referring to Fig. 6, the keying-device is arranged to short-circuit resistance 16 by a switch 17, and simultaneously to open a short-circuit across the grid coupling coil 9 by means of a switch 19. A single switch with front and back contacts may perform both functions.

Title: Improvements in or relating to electric heating elements
IPC: H05B3/68
Filed: 1955-10-08
Abstract: 815,368. Electric heating resistors. HULBERT, C. LACY-. Jan. 3, 1957 [Oct 8, 1955], No. 28710/55. Class 39(3) In an electric heater comprising one or more heating resistor wires 12 embedded in compacted insulating material in a metal sheath 13 or in grooves in the underside of a solid hot-plate, a rapid heating of the heater from cold is ensured by use of a control element comprising a wire 19 having a high temperature coefficient of resistance e.g. of nickel disposed so as to be initially heated entirely or substantially entirely by radiation from the main heater, with which it is connected in series. The control wire 19 is of nickel, iron or an alloy of these, and -may be helical and embedded in insulating material in a sheath 18 held by welded straps 24 close below the heating element. The control wire 19 is in series with the heating wire 12 which itself may be wholly or partly of a material with an appreciable temperature coefficient of resistance. The main heater may comprise a sheath containing a looped resistor with both terminals at one end of the sheath; and in this case the sheath of the control wire is of smaller diameter than the sheath of the main heater and is bent to a U-shape so as to have two legs adjacent opposite lower sides of a main sheath of triangular cross-section adjacent which it is 'held by straps. The main sheath may be of metal with the support straps welded to its lower edge. The control wire may be a loop embedded in a metal sheath with both terminals at one end and is in series with a similar main heater, in which however one length of the loop is of nickel heated by proximity in the sheath to the main heater wire. In order to supplement the heating by radiation of the control element, the sheath of the latter may be kinked at intervals so that the bent portions may be clamped in direct contact with the main sheath. The construction shown in Fig. 1 may be bent to a double spiral in flat form with the convolutions of the sheath of the control element between those of the heater. With a hot-plate comprising a metal casting with a heating resistance embedded in insulation in a spiral groove in its underside, the control element shaped preferably as a spiral is clamped closely adjacent its lower side by a strap so as to be heated by radiation therefrom. The control wire may be contained in a disc-like container instead of in a sheath. In another modification a sheath has a terminal at each end connected to a length of heating wire in the sheath and a length of the control wire is connected within the sheath between these two portions of heating wires, so that when the sheath is bent to a flat spiral, the length of sheath e.g. one quarter of the total containing the control wire is heated by radiation from adjacent convolutions of the heater. Specification 734,053 is referred to.
