Title: Method of and apparatus for removing dust from cupola waste gas
IPC: B01D47/06
Filed: 1958-06-25
Abstract: 847,551. Gas washers. STRICO GESELLSCHAFT FUR METALLURGIE UND WARMETCHNIK m.b.H. June 25, 1958 [Nov. 6, 1957], No. 20378/58. Class 55 (2). A method of removing dust from gases by spraying an ascending gas stream with water is characterized by such a local adaptation of the size of the water drops to the pressure of the ascending gas or by such local adaptation of the pressure to the droplet size, that a stationary layer of floating drops is maintained in the spray ing region. As shown, a suitable apparatus for carrying out such a process comprises housing 2 which is attached by extension 1a to cupola stack 1. Within the housing is secured an annular metal plate 3 having an annular channel 4 with a number of apertures 7 connected to downwardly sloping channels 8, below which is situated conical roof 6 to the stack, and which is suspended from the annular ring 3 by chains 5. Above the ring are situated, one above the other, two sets of nozzles 9 and 13. The holes of these nozzles are such that the droplet size increases with the spraying angle measured from the nozzle axis. As the drops fall, they are met by the upward gas stream 18 and the heaviest drops meet the gas flow at the region of greatest upward pressure near the walls. In this way a stationary layer of floating drops is obtained. The muddy water containing the dust collects in channel 4 and runs down channel 8 on to conical roof 6, and thence forms a falling curtain of water 20, which prevents spray entering cupola stack 1, before being run off through 17. If it is desired to reduce the upward gas pressure, casing 2 may be made of an upwardly divergent shape.

Title: Process for cooling cryocables
IPC: H01B7/29
Filed: 1975-05-15
Abstract: 1487499 Cryocables MESSER GRIESHEIM GmbH 15 May 1975 [15 May 1974] 20607/75 Heading H2C A process for cooling cryocables involves making a slush of low boiling point gas, i.e. liquid and solid, in a cooling station and pumping it along the cable between pumping stations. The slush is initially at the temperature of the triple point and so the temperature of the liquid only begins to rise when all the solid has melted, hence this process requires fewer pumping sections than one which passes only liquid through the cable. The slush is preferably prepared by the nozzle expansion process wherein liquefied gas or a low temperature gas at high pressure is expanded at pressures alternately above and below the triple point pressure. This process produces a fine grained slush which is easily pumped.

Abstract: 441,599. Scavengers' &c. vehicles. SOC. SOVEL VEHICULES, ELECTRIQUES INDUSTRIELS, 1, Rue Taitbout, Paris. July 22, 1935, No. 20749. Convention date, Aug. 6, 1934. [Class 108 (i)] In a vehicle for transporting material such as refuse, the vehicle is loaded at the rear and the refuse &c. drops by gravity in front of the rear panel to which is imparted movements of small amplitude so that the refuse is progressively distributed and compressed within the body as the loading takes place. Figs. 1 and 3 show two modifications of the method of filling and packing the refuse into the body 1. The rear panel 2 is provided with an upper opening bc through which the bin discharges its contents which fall by gravity in front of the panel 2 as represented by 5. The panel is then swung inwardly compressing the refuse as shown in Fig. 2 and the panel withdrawn to enable a subsequent bin loading to be discharged into the body. The rear panel 2 may be provided with a box-like portion 7 serving as the compacting device in which case the panel is provided with lateral wings 8 serving to form continuations of the body side walls when the panel is retracted. Figs. 7 and 8 show a vehicle in which the rear panel 2 is provided with the portion 7 and also with a chamber 9 serving to house and guide the bin 17. The bin is elevated by a cable 19 passing over pulleys 21, 22 to a hydraulic jack 27 and the bin is shown at 17<1> in its tipping position. The compacting movement of the panel 2 and portion 7 is performed by hydraulic jacks 10 removably linked to the panel at 16. When the contents are to be dumped the rear panel 2 with its chamber 9 is moved to the rear out of the way and the contents are discharged by means of a partition and movable floor or by tipping the vehicle about a rear pivot 29. The rear panel is moved out of the way by detaching link 14 from the panel 2 and operating a sector or sectors 29<a> by means of cables 30 from a jack 33, the sectors either being rigid with the box or chamber 9, or provided with a stop 34 adapted to engage a stop 35 on the box 9. Fig. 13 shows a body 1 having a curved depression at the rear end to enable the loading height of the panel aperture b<1> c<1> to be lowered and in this case a flap 401 is adapted to be raised by cables either manually or automatically during compacting to increase the effective area of the panel. Various forms of screens or gratings are described to aid the holding back of the compacted mass when the panel is withdrawn to receive another bin load. Fig. 18 shows such a screen 53 comprising bars and mounted thereon are prongs 59 which during the movements of the panel 2 are projected and retracted by means of a cable 67 operating in conjunction with a sector 68 and spring controlled levers 62. Stops 55, which may be retractable either by hand or automatically are provided to limit the movements of the screen 53.

Abstract: 1,028,878. Converting. BENDIX CORPORATION. May 20. 1964 [June 14, 1963], No. 20812/64. Heading H2F. A circuit converting from a high frequency to a low frequency has anti-parallel controlled rectifiers 77, 77A connected between the load and the high frequency source, and the control circuit for each rectifier has a bridge circuit delivering a sawtooth output at the high frequency which is modulated by a low frequency reference signal and amplified. The control signal generator (Fig. 6) receives signals from the high and low frequency sides and combine them to give control pulses for the thyristors which are pulse width modulated to give a sinusoidal output at the lower frequency. Each bridge, to which the high frequency input is applied, comprises two diodes and two R.C. circuits of different time constants, so that the bridge output is the difference of two decaying exponential waveforms - roughly a sawtooth waveform. This output is connected in series with the low frequency signal from transformer 73 and the resultant is amplified.

Abstract: 861,597. Carburetters. SOC. INDUSTRIELLE DE BREVETS ET D'ETUDES S.I.B.E. June 17, 1959 [July 11, 1958], No. 20843/59. Class 7(3). A carburetter having a float chamber comprising means adapted to make the chamber communicate either with the air intake 7 of the carburetter downstream of a filter 8 provided on the air intake or with atmosphere is characterized in that the means are mechanicalpneumatic means sensitive both to the negative pressure prevailing in the induction manifold downstream of the throttle valve and to the position of the valve and such that they cause the float chamber to communicate with the air intake when the engine is operating and/or with the atmosphere when the engine is stopped. Thus when the engine is not operating and the throttle valve 2 is in the position corresponding to the throttled down state of the engine the lever 17 acts on the rod 16 and holds the rod in the upper position (Fig. 1). Since the piston 14 is not subjected to any negative pressure it occupies its upper position thus opening the valve 13. If the engine is started up and is idling, the negative pressure acts on the piston 14 pulling it downwards and the valve 13 closes. When the throttle valve 2 is opened the rod 16 moves downwards under the action of the spring 21 and holds the piston 14 in its lower position. In a modification, Fig. 3, the tube 11 is shut off from the float chamber when the orifice 12 is opened. Specification 746,245 is referred to.
