Abstract: 845,942. Brick making machines. WHITTAKER & CO. Ltd., C. March 31, 1959 [April 1, 1958], No. 10374/58. Addition to 834,679. Class 87(2). In a modification of the brick making machine of the parent Specification, a hydraulic ram or rams is located in a cylinder or cylinders in a pressuretransmitting member of the machine other than a connecting rod thereof, variations in pressure of the hydraulic fluid in the cylinder or cylinders being transmitted by means responsive to such variation to adjust the position of the bottom plate of the mould. As shown in Fig. 3, rams A are located in cylinders B in the crosshead of the machine, the cylinders being interconnected and connected to a supply reservoir D through a back-pressure valve E and in communication with a plunger G. Thus any pressure applied to the pressheads F is transmitted to the plunger G which will tend to move against a constraining spring H, this movement being used to adjust the bottom plate of the mould and so control the density of the brick.

Title: Improvements in treating carbonaceous material
IPC: C10L5/06
Filed: 1920-04-15
Abstract: 151,236. Trent, W. E. Sept. 16, 1919, [Convention date]. Composition fuel.-Pulverized coal thoroughly mixed with water is treated with liquid hydrocarbon, e.g. crude oil &c., to agglomerate the carbonaceous particles into a heavy greasy mass and exclude ash-forming residues and water. Various quantities of water and oil may be used. Fig. 1 shows apparatus for continuous treatment. After a rough separation of slate &c., coal in the presence of water is finely ground in a tube-mill 1 rotated by gearing 2, 3. The discharge 5 leads to an hydraulic classifier from which water containing carbonaceous matter and detached impurities is conducted to the separator 7. The perforated pipe 8 is connected to the pump 9, which discharges the water and suspended materials through the tangentially - disposed nozzles of a revolving agitator 11 to separate the heavier impurities, such as iron sulphide. The current removes the lighter particles into the tank 14, the collected impurities being discharged through the conduit 14<1>. The stirrer 15 is slowly revolved and the particles settle whilst flocculent impurities overflow into the launder 16 and are discharged through the pipe 17. The carbonaceous mass is conveyed through the pipe 18 by a pump 19 to the chamber 20, air being supplied if desirable through the valved pipe 21, water through the pipe 23 and oil through the conduit 24. The mass is discharged through the nozzles of a slowly revolving agitator 27, and a conduit 29 leads to the pump to facilitate agitation. The suspended material flows into the conveying-pipe 31, whence it proceeds to a second treating- chamber 34 and is then discharged into the receptacle 36. Additional water to wash away impurities is introduced through the nozzles 40 after the material has thickened and is removed through the pipe 35<a> and decanter 37<a>. The collected material is discharged through the pipe 41. In a modification, the water and suspended material remains in the chamber during the period of treatment, valves which admit the material and the oil being closed whilst the commingling process is carried out.

Filed: 1927-04-20
Abstract: 281,597. Hõttich, A., and Kuhn, F. Dec. 6, 1926, [Convention date]. Bell and audible signalling systems; signalling over power circuits.-Signal receivers' at a plurality of stations are operated over a direct current distribution system upon the reversal of the polarity of the mains in response to the actuation of a transmitting switch at any station. Bells q, q<1>, Fig. 2, at stations A, B are connected in series with rectifiers t, t' across the mains of a D.C. distribution system supplying lamps k. When a switch such as n is operated, a bell x at a central station is rung. An operator then reverses a switch u to change the polarity of the mains i<8>, i<9> and thereby allow the rectifiers t, t<1> to pass current and operate the bells. In a modification the bell x is replaced by a relay which reverses the polarity automatically. The Specification as open to inspection under Sect. 91 (3) (a) comprises also systems in which the rectifiers are omitted. Fig. 1 (Cancelled) shows a three wire distributing system wherein the bells q, q<1> at the different stations are connected between neutral and earth and the contacts j, j<3> of the transmitting switches n, n<1> are connected to the outers. When one or other of the switches is operated both bells are operated over a circuit including one or other of the generators z<1>, z<2>. If a fault develops on the outers, the bells are rung until they are short circuited by operation of one or other switch n, n<1> into engagement with contacts j<1>, j<2> which may be used to facilitate signalling while the fault exists. A similar system may be employed in combination with a four-wire three phase system of distribution. This subject-matter does not appear in the Specification as accepted.

Abstract: 854,990. Treating gases with discharges. ELEKTROPHYSIKALISCHE ANSTALT B. BERGHAUS. April 2, 1957 [April 2, 1956], No. 10763/57. Addition 804,916. Class 39(1). A process for carrying out chemical reactions by means of the action of a glow discharge on substances introduced in a jet, into a reaction vessel as described in the parent Specification, is modified to include a starting procedure to concentrate the discharge on the cathode before the full operating conditions are established. The glow may be initially concentrated on the nozzle orifice as described in Specification 805,163. In the starting procedure the reaction vessel is evacuated and filled with a neutral gas such as argon at a pressure of 1-10 mm. Hg. The pressure is then raised above 20 mm., e.g. up to 200-220 mm. Hg. to concentrate the glow at the edge of the nozzle. The voltage also may be adjusted. The reaction gas, which may be a carrier gas for the substances to be reacted, may be admitted at a pressure of 5 atmospheres gauge. The pressure may be raised to the operating pressure in the starting- up procedure by introducing the carrier gas into the reaction vessel through the nozzle. In the apparatus shown the nozzle 8 and the vessel walls 2 are hollow for cooling, e.g. by water or liquid air. The rings 15a, 15b, 15c are anodes connected to an A.C. or D.C. source 19. A D.C. source is connected across anode 15a and the nozzle 8 acts as cathode. The nozzle may be the anode and ring 15a the cathode in which case it is cooled. The nozzle may be of insulating material and the discharge set up between separate electrodes. The neutral gas is admitted at 30 and pumped out at 33. The reaction gas is admitted at 21 and pumped out at 27. Powdered material may be added to carrier gas through an atomizer 24, or liquid material may be added to a carrier gas.
