Title: Improvements in dielectric heating apparatus
Inventor: MEREDITH ROGER JOHN
IPC: H05B6/76
Filed: 1967-01-04
Abstract: 1,207,511. R.F. couplings; microwave heating apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 3 Jan., 1968 [4 Jan., 1967], No. 464/67. Headings H4A and H5H. Microwave heating apparatus comprises a source 10, Fig. 1, such as a klystron or a magnetron, of nominal frequency (f n ), two resonators 1, 2 for different frequencies (f 1 ), (f 2 ) within a range extending above and below the frequency (f n ), a load 11, and interconnecting means 21 for the said source, resonators, and load. Dielectric material to be heated is drawn through the resonators 1, 2 in turn. As described, each resonator is a section of rectangular-section waveguide and a sheet of dielectric material is drawn through slots in the sides of each section in a direction which is at an angle of less than 90 degrees to the axes of the sections. The resonators may, however, be of other forms of waveguide, such as coaxial lines, strip-lines, parallel-plate lines. The interconnecting means 21 is a 4-port hybrid, but may be a 3 dB coupler, or be of the rat-race or magic-T type. The load 11 is resistive. The frequencies (f 1 ) and (f 2 ) may be equally disposed below and above the frequency (f n ) and it is arranged that when the actual frequency of the source 10 is outside the band between them energy reflected from one resonator is out of phase with energy reflected from the other resonator at the port A of the hybrid connected to the said source. In that case, the reflected energies at the port B connected to the load 11 are in phase. When the actual frequency of the source 10 is inside the band between (f 2 ) and (f 1 ) reflected energies from the resonators 1, 2 are in phase at the port A, but are kept at predetermined low levels by suitable choices of (f 2 ) and (f 1 ). In another embodiment, the output port B of the hybrid 21, which was connected to the load 11, is instead connected to a port A of a second hybrid 22, which has ports C, D connected respectively to two further resonators 3, 4. The said resonators have frequencies (f 3 ) and (f 4 ) equally spaced about the frequency (f n ) and respectively smaller and greater than the frequencies (f 1 ) and (f 2 ). The output port B of the hybrid 22 is in turn connected to a port A of a third hybrid 23, which has ports C, connected respectively to two further resonators 5, 6. The said resonators have frequencies (f 5 ) and (f 6 ) equally spaced about the frequency (f n ) and respectively smaller and greater than the frequencies (f 3 ) and (f 4 ). The output port B of the hybrid 23 is connected to a load 31.

Title: Improvements in the gasification and distillation of coal and other carbonaceous substances
IPC: C10J1/213

Abstract: 372,341. Distilling and gasefying solid carbonaceous materials. MACINTOSH, A. A., 25, Bendigo Avenue, Elwood, Victoria, Australia. Jan. 6, 1931, No. 486. Convention date, Jan. 20, 1930. [Classes 55 (i) and 55 (ii).] A process for the gasefication and distillation of coal or the like comprises distilling the material at constant pressure, and gasefying the non-volatile residue, or another carbonaceous material, in a gas producer in which the air pressure on the inlet side is maintained constant by a variable air delivery device controlled by the pressure of the delivered air, and in which the pressure of the gas on the outlet side is maintained constant by a pressure controller in the gas outlet, and mixing the distillation gas and the producer gas in any desired proportions. The apparatus comprises a horizontal retort 5 with off take pipes 6 leading to a condenser 9, having pockets 10 to accommodate static gas to assist in the condensing operation. A pipe 11 terminates in a pressure controller 12 of the kind described in Specification 105,563, [Class 55 (ii), Gas manufacture &c.], from which a pipe 14 leads to a gas exhauster main 17 having a gauge 18. A gas producer 19 is supplied with air from a blower 21, and the air pipe 20, which has a gauge 20a, passes into an evaporator at the top of the producer, and the air and steam enter through a pipe 23 below the grate. The producer gas passes through a dust collecter 27 to a pressure controller 29 communicating with the controller 12 by the pipe 14. A valve 31 in the air pipe byepass 30 is controlled by a bell float 33, the underside of which communicates by a pipe 32a with the pipe 20, so that the valve 31 is operated in accordance with the air pressure in the pipe 20. The air condensed from the retort distillates may be returned to the retort 5 down the pipe 6, this oil being fed in by a pipe 37a. The gases from the producer and retort may be washed with ammoniacal liquor to remove the sulphur compounds and carbon dioxide.
