Title: Relaxation Oscillator
IPC: H02M7/515
Filed: 1967-05-12
Abstract: 1,183,953. Semi-conductor pulse circuits. INTERNATIONAL STANDARD ELECTRIC CORP. 12 May, 1967 [13 May, 1966], No. 22155/67. Heading H3T. [Also in Division H2] A relaxation oscillator, particularly for triggering a pair of thyristors, `comprises a capacitor C1 charged via a current path and alternately discharged via respective ones of a pair of voltage-sensitive switches (such as fourlayer diodes D1, D2). As described, capacitor Cl is charged via a constant current transistor Q1 until one of the four-layer diodes (e.g. D1) breaks down, triggering a transistor or thyristor SCR1, forming part of an inverter. This action discharges C1 and charges C2 so that during the next charging cycle of C1, four-layer diode D2 will break down, triggering SCR2. In Fig. 3, capacitors C2 . . . C5 are omitted and reverse diodes are included between the gate and cathode of each thyristor. A resistor in the cathode circuit of each thyristor ensures that the four-layer diodes D1, D2 break down alternately.

Title: Process for separating out from gas mixtures the constituents that are readily condensable
IPC: F25J3/06
Filed: 1926-09-09
Abstract: 258,856. Ges. fur Linde's Eismaschinen Akt.-Ges. Sept. 25, 1925, [Convention date]. Condensing processes.-In the process of separating liquefiable gases from gas mixtures by compression, cooling and subsequent expansion of the gas and heat interchange between the cold expanded gas and the compressed gas, any water vapour present in the compressed mixture is condensed out in an evaporative cooler before the mixture is highly cooled in the heat interchanger. In the evaporative cooler water is brought into direct contact with the outgoing gas, and its evaporation and absorption produce a cooling effect. The invention is described as applied to the recovery of benzol from coke-oven gas. The gas to be treated passes from the compressor 1 and water-cooled spiral 5 to the coif 9 in tne evaporative cooler 8, condensed water vapour and any benzol being collected in a separator 6. The compressed gas flows from the separator 6 through one of two interchangers 3 and is cooled therein by the gas returning from the expansion cylinder 2. The benzol is collected in separators 4 and delivered to stock tanks. The interchangers are alternately used and thawed for removal of ice &c. The gas is expanded to approximately atmospheric pressure and returns from the interchangers 3 to the bottom of the cooler 8, where it meets a descending stream of water. The expansion motor preferably assists in driving the compressor.

[Also in Group V] In a dispenser cathode, in which emissive material 11 is contained in a recess in a holder 5, which recess is closed by a porous sintered wall 10 of refractory metal powder, the holder itself is also of sintered metal powder, but impervious. The H-section holder 5, and closure 10, are pressed separately, and then sintered together after assembly, preferably in vacuum or a hydrogen atmosphere. The metal powder for forming the holder is of smaller grain size than that for the closure, is compacted more firmly, and sinters at a lower temperature, so that after firing, the holder is impervious, while the closure remains porous, and is frangible enough to be machined to size without filling up the pores. Molybdenum for the holder, and tungsten for the closure, are preferred materials The holder is pressed in a mould, Fig. 1 (not shown), the upper recess being tapered; the closure is similarly tapered, so that it fits exactly and flush. In the modification of Fig. 4 (not shown) the closure takes the form of filling the whole recess with the tungsten powder.
