Abstract: 402,837. Automatic exchange systems. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, Liverpool, and TAYLOR, R., 30, Oulton Road, Wavertree, Liverpool. June 11, 1932, No. 16592. [Class 40 (iv).] A two-directional final selector having two sets of wipers selected in accordance with the means of access to the selector is provided with P.B.X. hunting facilities over groups of lines connected to the bank of either set of wipers. For this purpose, two auxiliary trailing-wiper banks PBX1, PBX2, are provided and these banks may be formed of superposed plates assembled in a single structure in the manner described in Specification 391,123. If the selector is seized over the upper conductors, wipers-1, + 1, P 1 and bank PBX 1 are employed, but if seized over the lower conductors relay WS operates over the calling loop, locks to the test wire 13, switches through to the impulse relay A and changes over to the other set of wipers and bank PBX2. The tens impulses are repeated by relay A to vertical magnet VM over a winding of relay C which is energized over its other winding and normal contacts N2 upon seizure of the switch. At the end of the digit the relapse of C energizes E which switches over to the rotary magnet RM and re-energizes C over rotary normal contacts NR1. At the end of the final digit, relays C, E release in succession completing a testing circuit over relay H. If the selected line is busy and is the first line of a group relay HS operates over one of the P.B.X. banks completing a circuit over its own left-hand winding for the rotary magnet RM and relay C which in turn operates relay E. A similar test is made of the second line and stepping proceeds until an idle line is found or until the last line of the group is reached when relay HS releases due to the corresponding position in the P.B.X. bank being disconnected. Relay G operates to give the busy signal. If an idle line is found, relay H operates to connect up ringing-current and when the called subscriber replies relay F operates and connects up the back-bridge relay D which is connected to the condensers QA, QB, over contacts of F to prevent interference with impulsing. Release is effected by advancing the wipers to the end of the bank under the interaction of magnet RM and relay G.

Title: Improvements in or relating to adsorption or absorption processes
IPC: B01D53/02
Filed: 1936-06-18
Abstract: In gas - separating processes such as the recovery of olefines from distillation gases by means of solid adsorbents or liquid solvents, the first fraction of gas expelled in the regeneration of the absorbent medium is reabsorbed in a medium which has already been charged in the normal way, whereby a further concentration of the valuable constituents is effected. Impurities such as carbon dioxide may be removed by scrubbing before the second absorption.  The second fraction of the expelled gas may also be treated in known manner for removal of some of its constituents and the residual gas then treated in the same way as the first fraction.

Title: Improvements relating to oil burners
IPC: F23D11/24
Filed: 1957-05-29
Abstract: 843,641. Oil burners. SMITH, C. H. May 20, 1958 [May 29, 1957], No. 17078/57. Class 75(1). In an oil burner having an air tube 14 carried on the fuel tube 8 fitted with the atomizing nozzle 9. the two being bodily adjustable relatively to the burner mouth 3 a quick shutting off or opening of the oil flow to the nozzle 9 is effected by placing the shut-off valve within the fuel tube 8 and closely adjacent to the nozzle 9 the operating stern 35 for the valve being extended to a control at the remote end of the burner body; the oil supply and discharge pipes 27, 28 are connected to the fuel tube at such remote end and outside the burner body. The shut off valve may be a needle valve or a neoprene pad provided at the inner end of the stem 35 to close down on the seating 36 the aperture of which is many times greater than the discharge aperture of the nozzle so facilitating separating out of air bubbles in the oil supply. The fuel tube 8 has fixed thereto a hemi-spherical head 13 on which the air tube 14 is relatively angularly adjustable to vary the effective area of air entry ports into the interior of the air tube these variable air entry ports being provided by the partial registration of inter-castellation apertures 23 on the top rim of the air tube with those of a depending flange 15 on the hemispherical head 13. This turning adjustment is effected by slightly turning the top cover 2 of the burner on its cylindrical body portion 1 as permitted by the screw and slot connection 26, it being noted that turning of the air tube 14 is prevented by a key piece 21 fixed on the burner body portion 1. Axial adjustment of the air tube and nozzle relatively to the coned exit end 3 of the burner is effected by an internally screwed hand wheel 12 (or toothed or worm wheel) which raises or lowers the fuel tube 8, rotation of the latter being prevented by the oil inlet and discharge pipes 27, 28 which are fixed to the fuel tube 8 and restrained against turning movement in the horizontal plane by their extending through a vertical slotting 29 in a boss 10 on the burner top 2. The air is supplied by a fan to a tangential inlet 31 to the burner part passing to the interior of the air tube and past the nozzle 9 and part passing outside the air tube where it passes over helical vanes 32 to reach the burner mouth 4. The control means for operating the valve stem 35 is a bellows which collapses upwards when the oil pressure is set up by closing a valve in the oil discharge pipe 28, this may be effected by remote control e.g. electrically.
