Title: Improvements in and connected with gas producers
IPC: C10B1/04
Filed: 1921-11-19
Abstract: 182,053. Dowson & Mason Gas Plant Co., Ltd., and Wilson, E. Nov. 19, 1921. Charging; charges, agitating.-A water-cooled charge-stirring device for a gas-producer comprises rotatable horizontal arms 7 mounted to oscillate on their own axes and having depending fingers 8 which dig into the uppermost layer of the charge. In the construction shown, three arms 7 work in the gap 50 between the upper and lower portions of the producer shell, each arm being supported at its outer end in a bearing 9 on a carriage 14 running on a rail 15, and at its inner end in a bearing 10 in a housing 11 carried by a pipe 20 depending from a casting 21 mounted on ball bearings 22. The three carriages 14 are connected by a circumferential rack 16 driven by a worm 17, and escape of gas through the gap for the arms is prevented by water seals 13, 47. The casting 21, which carries the spreader plate 23 for distributing the fuel evenly in the producer, drives through the bevel wheel 34 and a variable-speed gear 35, the hopper drum 27. For cooling the apparatus, water is fed into the seal 38 between the hopper and the casting 21, and passes thence by way of the pipes 39, 20 to the casting 21, from which it overflows into a trough 40 connected by a pipe 42 with the water seal 13. From this seal the water passes through the pipe 43 running the length of an arm 7, and returns to a box part 3 at the outer end, the overflow from the box passing to the lower seal 47, and thence to a sump. The box 3 is extended, as shown in Fig. 2, to carry weights 45 by which the leverage of the fingers 8 can be varied.

Abstract: 743,072. Gas meters. PARKINSON & COWAN, Ltd. Dec. 9, 1953 [Dec. 11, 1952], No. 31406/52. Class 54. A dry gas meter of the type in which the meter casing is made up of at least two parts, one of which carries an outlet pipe 51, Fig. 4, having its inner end connected in a gas-tight manner with an exhaust port 45 located at some position within the meter casing is characterised in that a resilient sealing ring 49 is used to effect the gas-tight connection. This ring, which may be of rubber or synthetic rubber is mounted in an L-shaped recess 47 and has an internal diameter slightly smaller than that of the exhaust port 45 and the outside diameter of the pipe 51 so that it is compressed as the latter enters the port during assembly. An L-shaped recess 55 may also be provided on the pipe 51 and be positioned so that the ring 49 is compressed vertically as well as radially. The port 45 may be formed, as shown, in a pipe 53 extending upwardly from a valve seating plate 58 forming the top of a casing for the gas distribution chamber or in the plate 58 itself. In meters of the type in which exhaust gas fills the space below a horizontal partition 14, Fig. 5, the pipe 51 passes through an aperture in the partition and is sealed by the ring 49 which is held in place by a retaining plate 61.

Class 117 [Also in Group XIII] A method of simultaneously drying and cleaning seed includes the steps of initially subjecting it to the action of heated air to bring moisture in the seed to the surface thereof, and immediately thereafter screening the seed to remove foreign matter, the screening step being accompanied by a further heating action to dry the seed. Seed flows from a shoot 2 to a hopper 1 having fine mesh walls 3<SP>1</SP> and, during its relatively slow passage to a reciprocating feeder 10, is subjected to heated air delivered by a fan in a casing 8 which flows over electric heating elements 7 and through wire mesh 3<SP>2</SP> surrounding a louvred container 4. As the seed falls from the feeder 10 it passes an air current, which may be heated, delivered by a fan 12 whereby dust &c. is removed to a box 13 and the seed falls to superimposed heated screens 14. The screens have discharge shoots 16, and each screen comprises spaced sections 22 of electrically conducting material, such as wire mesh, extending between the wooden sides 20 of a frame and wooden bars 21. The sections of each screen are connected electrically in series and are supplied with current from atmosphere 28 by leads 26, 27.
