Title: Improvements in or relating to the operation of coal dust furnaces
IPC: F23K1/00
Filed: 1934-08-14
Abstract: 441,940. Centrifugal pumps. GRAEMIGER, B., 29, Guggerstrasse, Zollikon, and HEPHAEST AKT.-GES. FUR MOTORISCHE KRAFTERZEUGUNG, 12, Freigutstrasse, both in Zurich, Switzerland. Aug. 14, 1934, No. 23458. [Classes 110 (i) and 110 (iii)] [See also Group II] In a device for supplying pulverized coal to a furnace comprising an axial blower, a centrifugal compressor and a back pressure engine which are mounted on the same shaft, the compressor supplies the air for operating a pneumatic pulverizer which feeds the fuel directly into the furnace whilst the blower supplies the whole or a portion of the combustion air. The air-jet mill 12, Fig. 1, is fed from a hopper 7 and discharges the coal dust to a burner 8 in a steam generator 1. An engine or turbine 5 drives a compressor 6 and blower 23 and is supplied with steam by a pipe 25 from the boiler, an intermediate stage in the turbine being supplied with steam through a temperature-controlled byepass 26, the exhaust pipe 4 discharging its contents into a feed water heater and/or air heater. The compressor 6 supplies air heated in the pipe 26 to the pulverizer and the blower supplies combustion air to the boiler through a pipe 10. A feed pump 2 supplies the boiler through pipe 9. In Fig. 2, a jet pulverizer 12 is supplied with air from a compressor 6 driven by the turbine 5 the exhaust steam from which heats the air at 18 or feed water at 19 before passing into the feed water heater 21. The throttle valve 22 of the steam turbine may be controlled by the temperature and pressure of the steam in the pipe 4. In Fig. 4, is shown a turbine 53, centrifugal compressor 52 and blower 51 mounted on a shaft 50, the exhaust steam from the turbine passing through coils 62. The combustion air passes from chamber 60 around the heating coils and is discharged through orifice 63. The air for the jet pulverizer is drawn by the compressor 52 from the chamber 60 and is discharged through heating coils in a separate chamber in the bed plate. The bed plate may be used for mixing steam with the feed water or may be used as a surface condenser, the pulverizer air being passed through the cooling tubes. The control of the steam supply to the turbine 30, Fig. 3, may be effected by the variation in pressure in a pipe 39 due to the flow of steam in the pipe 40. The steam valve 33 is connected to an arm 34 which is connected at one end to a spring-controlled piston 36 operated by the pressure in pipe 38 and at the other end to a bell 41 sealed in liquid 42 and maintained against stops 46 by a spring 43. A tapping from the air pipe 44 from the compressor leads to the outside of the bell. When the pressure in the steam pipe 40 increases the piston 36 descends and reduces the steam supply to the turbine 30. When the pressure of air in the pipe 44 increases the bell 41 descends and reduces the supply of steam to the turbine.

Title: System for simultaneous transmission of several pulse trains
IPC: H04J3/06
Filed: 1976-06-08
Abstract: 1501358 Data transmission; synchronizing COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL SA 8 June 1976 [4 July 1975] 23631/76 Headings H4M and H4P In a data transmission system, synchronization signals, e.g. for frame synchronization, are transmitted as violations of the bipolarity of a main pulse train transmitted in a bipolar format, whereby a separate transmission path or channel for the sychronization signals is not required. As shown, two pulse trains B and C, for synchronization purposes, are derived as submultiples of the frequency of a main pulse train A. The pulse train A is converted into a bipolar form for transmission, but where a pulse in train A coincides with a pulse in train B, a single bipolar violation is introduced into the train A, whilst a pulse in train C introduces a double violation of bipolarity, whereby a pulse train having the form E is produced for transmission along a path between a transmitter and a receiver. In the receiver, the single and double violations of bipolarity are detected, whereby the original pulse trains can be reconstituted as trains A<SP>1</SP>, B<SP>1</SP> and C<SP>1</SP>. Suitable circuit arrangements for the transmitter and receiver are described with reference to Fig. 1 (not shown).

Filed: 1932-08-26
Abstract: <PICT:0398023/III/1> Sulphur dioxide is obtained from sulphuric acid sludges such as those obtained in the purification of petroleum &c., by bringing the sludge into direct contact with hot combustion gases. In the treatment of the sludge the temperature may increase sufficiently slowly to prevent the presence of sulphur trioxide in the resulting gases.  A carbonaceous residue which serves as a granular fuel is also obtained.  The combustion gases may be obtained by the combustion of sulphur containing material and preferably contain free oxygen.  The sludge and combustion gases may contact in a plurality of reaction zones at gradually increasing temperature, one of the zones being maintained at a temperature at which water is evaporated and light hydrocarbons distilled, e.g. 312-300 DEG  F., another zone being maintained at a temperature below that which would result in the formation of hydrogen sulphide or the distillation of sulphur trioxide, e.g. 300-400 DEG  F. and if desired a third zone being maintained at a temperature sufficiently high to convert the carbonaceous residue into a granular fuel, e.g. 400-420 DEG  F.  The sludge and combustion gases preferably move in countercurrent. Sulphuric acid sludge is charged continuously into a rotary retort 10 having a heat insulating lining 11 through a feed pipe 22 and flows in succession through compartments I, II and III, which are separated by annular baffles 12, 13, the carbonaceous residue discharging into a hopper 21.  Simultaneously, hot combustion gases from a furnace B are injected through a nozzle 20 and the sulphur dioxide containing gases leave through an outlet 23.  Flights d, d are provided to agitate the charge and these may be supplemented by iron rods or rails which are elevated and dropped by the flights. The retort 10 is provided with reduced cylindrical end sections 14, 15.
