Abstract: 385,161. Refrigerating. GRUBER, E., Richmond Road, Lyndhurst Village, Ohio, U.S.A. March 29, 1932, No. 9061. [Class 29.] Absorption machines.-In machines working on the reversing system and having a separate condenser member and a drain pipe to return solvent from the evaporator 27 to the generatorabsorber 1, the return gas pipe from the evaporator is arranged to byepass the condenser or the condenser and rectifier, and to enter the generator-absorber below the drain pipe. Gas from the generator-absorber rises through a pipe 9 to a vessel 10 and descends a pipe 11 to a liquid trap 8, whence it flows through a forked pipe 12 to the lower end of the rectifier, which comprises a narrow annular space between concentric tubes 15, 16, one or both being gilled for air cooling. The gas then passes through a pipe 18 to a concentric tube condenser, the interior 19 of which may be cooled by thermal flow of water from and to a tank 37. The condensate collects in a sump 23 in the condenser and rises through a pipe 24 to a large bore pipe 25 leading to a dome 26 of the evaporator. The drain pipe 29 leads upwards from a well 28 in the evaporator and passes through the vessel 10 and then down to a connection 32<11> with a pipe 7 leading from the trap 8. The gas return pipe 33 extends from the large bore pipe 25 to a connection 34 with the pipe 7 just below the drain connection 32<11>. The pipe 7 connects at 6 with the rising limb 2 of a loop 3, 4 through which liquor circulates during the absorption period. The drain pipe has a widened portion 31 acting as a gas chamber during the generating period, and its lower end is inclined upwards to the connection 32<11>, while the end of the gas return pipe is inclined downwards to its connection 34. In a modification the gas returns through the rectifier, a gas byepass passage 40, 41 and mercury seal 38 being provided, as shown in dotted lines, between the pipe 25 and the pipe 18.

Title: Means for preventing the spreading of high density electron beams
IPC: H01J25/02
Filed: 1943-06-11
Abstract: 579,371. Discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. June 11, 1943, No. 9486. Convention date, June 15, 1942. [Class 39 (i)] Spreading of an electron beam by space charge repulsion within a long conducting tube 14, such as the drift space of a velocity-modulation device, is prevented by trapping within the tube a sufficient number of positive ions to neutralize the space charge of the electrons. It is shown that there is sufficient gas present, even in commercial vacua of 10<-6> to 10<-9> mms. of mercury, to produce a sufficient number of ions, and the previous failure of gas focusing at those pressures is stated to have been due to the leakage of positive ions from the ends of the tube under the influence of the negative gradient existing between the edge and the centre of the beam. If one or both of the electrodes 13, 15 is held at a positive voltage slightly greater than this negative gradient, the leakage is prevented and the space charge of the beam is neutralized. The end facing electrode 13 is most prone to leakage, owing to the proximity of the cathode 10 and first anode 11. As shown, both electrodes are joined together to a source V3, which may be a battery or a dropping resistance operating on the electron current collected by electrode 14. V3 is 10-15 volts for a 6000 volt, 50 milliamp. beam, but nearly 1000 volts for a 5 amp. bearii ; it is proportional to the current and inversely proportional to the voltage. At high vacua, care must be taken that the envelope is of sufficient size to provide an adequate volume of gas, according 'to a formula which is given ; at such vacua almost all the gas molecules will be concentrated as ions in tube 14, the rest of the envelope being nearly empty.
