Title: Crossed-field electron discharge device
IPC: H01J21/14
Filed: 1963-01-17
Abstract: 969,833. Magnetron amplifiers and oscillators. RAYTHEON CO. Jan. 17, 1963 [March 15, 1962], No. 2163/63. Heading H1D. In a crossed-field electron discharge tube such as a magnetron or an amplifier tube with re-entrant electron stream and non-re-entrant wave propagating structure as described in Specification 928,540, the cathode 22, Fig. 1, as shown in a multi-cavity strapped magnetron, has a sharp edge 23 coated with electron emissive material 24 in order to produce arcing and consequent ionization of gas molecules. Heating and secondary emission is produced by back bombardment to sustain electron flow after operation is started by the initial concentration of electrons. Minute wires may be disposed along the sharp edge, the wires consisting of tungsten plated with rhenium, iridium or platinum to avoid a gettering action by the tungsten. As shown in Fig. 5, the cathode body has a good thermally conductive central layer 48 and outer poor thermally conductive layers 49, 51 to act as heat reservoirs. The cathode is supported, Fig. 1, by a stem 21, the lower end of which is slidable in an insulating sleeve 27 or the cathode may be supported from one end plate 2, 3 only. In Fig. 7 there are two disc-shaped cathode bodies and end shields 64, 65 are provided as shown with tilted edges, or with bulbous edges or in another embodiment with flat end shields held at a positive potential in order to concentrate the electric field in the vicinity of the cathode edge.

Title: Method and apparatus for removing foreign particles from a gaseous medium
IPC: B04C3/00
Filed: 1957-01-22
Abstract: 858,897. Centrifugal apparatus. JOY MANUFACTURING CO Jan. 22, 1957 [March 15, 1956], No. 2255/57. Class 23 [Also in Group XII] In apparatus wherein a gas containing foreign particles, e.g. air containing dust, is wetted with a liquid, e.g. water (see Group XII), the wetted foreign particles and surplus liquid are subsequently removed in a centrifugal separator. As shown in Figs. 4a and 4b which together show the complete apparatus air containing dust is wetted with water in a device 20 and passes to the space between a core 32 and the casing 11, a rotary movement being given to the air by stationary vanes 46 whereby water, with wetted foreign particles, is separated from the air stream centrifugally. To prevent water from adhering to the core 32, the stationary nose part 30 is followed by a rotating part which is journalled at 36, 40 and is driven by vanes 48 which make an angle of from 3 to 7 degrees to the direction of flow imposed upon the air by the stationary vanes 46 which latter support the nose part 30 from the casing 11. The water is collected in a series of annular spaces 50, 52, 54 to which access is afforded by passages 62, 64, 66 between sections of the easing 11, a drain 80 and suction pump 81 being provided. Water which fails to reach the spaces 50, 52, 54 is mostly contained in the outer layers of the rotating air, and these layers are stripped off into the opening 110 between a. cylindrical member 98 and a frusto-conical wall 100 having apertures 115, 117, 119 leading to water-collecting spaces 90. The strippedoff air passes through an annular passage 112 to rejoin the main stream, but the increasing cross-section between the members 98, 100 leads to a decrease in air velocity and deposition of water on the outside of the member 110, this water and the water from the spaces 90 passing to the drain 80. Apertured partitions 104, 106, 108 tend to project the water through the apertures 115, 117, 119. The air flow is straightened by vanes 130 before passing to the fan. In a modification, the diverging space between the members 98, 100 is occupied by a helical ribbon which promotes the centrifugal removal of water from the stripped-off air. In a further modification, the diverging space eliminator is omitted, and a section of the casing 11 is arranged to rotate with the core 32 so that the centrifugal effect is amplified at the last stage of water removal. With an appropriate alternation of drainage means, the apparatus may be arranged in in vertical or inclined position instead of in a horizontal position.

Title: Improvements in or relating to sorting machines of the manual control type
IPC: B07C3/04
Filed: 1943-02-16
Abstract: 576,471. Sorting cheques &c. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 16, 1943, No. 2564. Convention date, April 24, 1942. [Class 117] In cheque &c. sorting machines of the type' described in Specification 435,139, [Group XV], the capacity of the machine is increased by duplicating the sorting drums and driving them from the same motor, means being provided for selecting a particular drum, while leaving the others out of operation. The selecting means is an electric circuit with each drum and controlled by a keyboard common to all the circuits in conjunction with a changeover switch. The drums A, Fig. 3, are belt driven from pulleys 52 loosely mounted on a shaft driven from the motor 10. Depression of a key energises a solenoid to throw in a clutch connecting the appropriate drum with the shaft. A commutator device carried by the drum opens the circuit of the solenoid when the drum has reached its predetermined position and at the same time energises the solenoid 109 which actuates a stop 122, to retain the drum in this position. The depression of the key also energises a solenoid S.M., Fig. 5, which withdraws a blocking shutter 100 in the shoot 167 by which the cheques are placed into position for delivery to the sorting compartments of the drum. The cheque feeding devices consist of rollers 130, 131 and two intergeared rollers 37 at the entrance to the compartments. The roller 130 is driven through a friction clutch from a shaft 136 driven continuously from the shaft 132, and is held stationary by a pivoted catch 140. The shaft 132 drives through a one revolution clutch the shaft 146 which has a profile cam 145 and face cam 153. The cam 145 releases the catch 140, and the cam 153 swings a frame 148 about the shaft 136. This brings a gear 155 into mesh with the gear rollers 37 and causes them to feed the record into the sorting drum compartment. The one-revolution clutch is actuated by a bar on the keyboard, which is automatically returned to neutral position for repetition movements. The control keys are released by subsequent operation of another key. The Specification as open to inspection under Sec. 91., describes also an arrangement in which two machines are controlled by separate keyboards. This subject matter does not appear in the Specification as accepted.
