Title: Improvements in or relating to the heat treatment or carbonisation of coal
IPC: C10B49/04
Filed: 1925-10-26
Abstract: 242,621. International Combustion Engineering Corporation, (Assignees of Runge, W.). Nov. 6, 1924, [Convention date]. Coking processes.-Pulverized coal is preheated by suspension in a hot oxidizing gas and then carbonized by being showered through an ascending current of gas at a higher temperature. By preheating in air at a temperature of about 650‹ F. the agglutinating properties of bituminous coal are destroyed and the powdered fuel is then carbonized by being passed through the ascending combustible gas at a temperature of about 1000‹ F. Dried powdered fuel is showered by a device 7 into a preheating retort 9, the air for which is heated in a coke cooler 29, and, if necessary, a heat interchanger 32 before being delivered into the bottom of the retort, and, if desired, into a jacket 37 surrounding the retort, the resulting gases escaping by an outlet 12. The preheated powdered product is supplied by a conveyer 13 and feeder 15 to the top of a retort 17 in which it meets an ascending current of combustible gas heated in a heat interchanger 28, this gas being supplied if desired to a jacket 40 and direct to the carbonizing zone by a pipe 41. The distillates are led by a pipe 21 to a purifying apparatus 22 and gas holder 23 from which a pipe 26 leadsto a burner 27 and a pipe 25 to the heat interchanger. A controlled amount of air may be admitted to the carbonizing retort as described in Specification 242,622. The powdered coke is transferred to a cooler 29 in which it is utilized to preheat the air for the preheating retort.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1936-10-05
Abstract: 474,653. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., and COLLYER, J. E. Oct. 5, 1936, No. 26935. [Class 40 (iv)] One of a group of finder switches normally acts as an allotter for the remainder, but may be used as a finder when all the remainder are busy. Selection of an idle finder when the allotter is in use as a finder is effected by a relay chain. In the system shown, Fig. 2 shows the circuits of the finder which serves as an allotter, the circuits of the other three finders being identical except that start relay S, bank D4, and the lead over contact qd6 are omitted. When a call is made, line relay L operates partially to close its contact L3 and relay S operates to close a starting circuit over wiper D4 for relay PC, say, of the third finder. Relay PC connects the stepping magnet to the test-wiper and when the calling line is found relay QC (not shown but similar to QD) operates, connecting ground to the test-wiper to operate relay L fully, and disconnecting relay PC. During the release time of PC, the stepping magnet D of the allotter receives an impulse over wiper D4. When all the ordinary finders are busy, relay PD operates for the next call and the allotter acts as a finder, further allotments when any of the ordinary finders become free being made by the relay chain, Fig. 3. With the arrangement shown, relay PD will be operated when wiper D4 is connecting up relay PC and the third finder is busy. Normally the allotter will take one step under these conditions and relay PD will then be disconnected and release, and one of the ordinary finders will be allotted. If however, the allotter happens to be standing on the calling line, relay QD will operate at once and the link including the allotter will be used for the call. To prevent this, the circuit of relay PD may be modified so that it can only operate when all of the relays QA, QB, QC, are energized and therefore all ordinary finders are busy. Busy tone may be supplied when all the ordinary finders and the allotter are busy. Specification 235,771, [Class 40 (iv)], is referred to.

Abstract: 187,223. Farbwerke vorm. Meister, Lucius, & Br³ning. Oct. 10, 1921, [Convention date]. Purifiers; purifier waste, revivifying.-Apparatus in which gases are purified by means of charcoal and then prepared for reuse, is so constructed that these steps are performed in one continuous operation. The annular sieve-drum 3 is subdivided by radial imperforate partitions into a series of narrow sectors containing charcoal, and the annular space between the drum 3 and the closed cylindrical casing 1 is divided by partitions 2. Gas entering at A passes radially through the charcoal, from which the absorbed constituents are recovered by rotating the drum so that sectors containing absorbed gas are subjected to the action of steam introduced from inlets 4. The mixture of steam and liberated gas leaves the apparatus at 5 for condensation and recovery, any residual gas being returned by the inlet 6. The gas originally introduced at A passes again through the charcoal at B, thereby cooling and drying the charcoal, and the gas having been cooled, it is passed again through the charcoal by means of the inlet D to complete the cooling process, and is finally withdrawn at E. The gas streams and the steam current may be applied axially instead of radially, and it is also stated that the system of supply pipes may be rotated. The apparatus is described with reference to the removal of benzene from illuminating gas.
