Title: Improvements in or relating to wireless signalling systems
IPC: H04L1/02
Filed: 1927-01-14
Abstract: 264,521. Marconi's WirelessTelegraph Co.,Ltd., (Assignees of Ranger, R. H.). Jan. 15, 1926, [Convention date]. Transmitting and receiving systems for code telegraphy; automatic telegraphy.-In wireless signalling a message in code is transmitted a plurality of times, for instance twice, in a manner analogous to multiplex signalling with a small time interval between corresponding parts of the transmission and the speed of a motor actuating a control device at the receiver is governed by a synchronizing device actuated in accordance with the received signals. A perforated tape 19, Fig. 1, passes in succession through .controllers 5, 6, which are brought into operation alternately by commutators 11, 12 and control a transmitting-set 1 through a relay 17. The transmission due to the controller 5 is as exemplified at d. Fig. 3, that due to controller 6 as at g, the combined transmission being as at h. At the receiving station, Fig. 4, recorders 27, 28 operate alternately and synchronously with the controllers 5, 6 through the action of commutators 31. 34 driven by a motor 37 synchronized with the driving-motor 8, at the transmitting station. If the time taken by the loop 38 of the receiving tape to pass from recorder 28 to recorder 27 is equal to the time taken by the loop 19 to pass from controller 6 to controller 5, the two received signals of corresponding parts of the message appear side by side on the tape, as shown in Fig. 5, so that atmospherics can be distinguished by inspection. According to a modification the recorders are connected in shunt with brushes 29, 32 with the recorders in series instead of as illustrated. Under specially good signalling conditions the system can be used for multiplex signalling. Synchronous movements. - The motor 37 is arranged to run slightly slower than the motor 8 and is synchronized as follows. The end of a received signal tends to produce a positive potential at the grid end of the secondary of a transformer 25, Fig. 4, which is short circuited by a commutator 42 bridging contacts 41 whenever commutators 31, 34 are switching from one recorder to the other. If the motor 37 is not running synchronously with the motor 8, the positive potential is communicated to the grid of the valve 43, and so reduces the grid bias from a battery 44 that current flows through the valve. This reduces the potential on the grid of a valve 48 with the result that less current flows through a relay 61, thus short-circuiting a resistance 53 and speeding up the motor 37. Owing to a condenser 45 placed across the filament and plate of the valve 43, synchronization is obtained by the integration of a series of correction impulses.

[Classes 50 and 55 (i).] In the carbonization of coal, shale, peat or other carbonaceous material, and the hydrogenation of the distillates, the material is passed through a shaft or retort in contact with a hot combustible gas which has been heated and electrolysed by an electric arc causing dissociation of its hydrogen. As shown in Fig. 1, the coal descends through a shaft a on to a layer of coke supplied from a hopper k on to a travelling grate b, the gas from a pipe g being dissociated by an electric arc f in a chamber e, and passing under an arch l into contact with the coal during its passage below the roof m to an outlet j. A further admission of hot gases to the tower a may be made through a duct h. In Fig. 2, the hydrogenation takes place as the material passes down a long retort a having the electrodes f and gas inlets g<1> at the bottom, the distillates escaping from an outlet j at the top, and the coke being removed by a conveyer z. The unsaturated hydrocarbons are hydrogenated to give a liquid fuel of low specific gravity, and petrol. The coke may be purified and hardened by treatment in a separate chamber with steam superheated by passage through an electric arc. Condensers p, q for heavy and light oils, are shown.

Abstract: 437,154. Scavengers' vehicles; separating. CAMBESSEDES, J. E. F., 18, Boulevard Arago, Paris. Jan. 18, 1935, No. 1796. [Class 108 (i)] [See also Group II] An apparatus for sorting household rubbish and depositing it into compartments in the vehicle body is adapted to be mounted on and dismounted from, the body of the collecting vehicle. The apparatus comprises a casing consisting of uprights 11, Fig. 2, connected by brackets 12 to the top of the vehicle body 3, the uprights 11 having interior aluminium linings 13 to provide a space for the sorting mechanism and outer casings 14 between which and the upright are housed the driving arrangements of the sorting mechanism. At the rear of the vehicle a casing 30, Fig. 1, is pivoted about a shaft 24, the casing housing the feeding conveyer 26 provided with buckets 29 at irregular intervals, and a feeding hopper 31 provided with a grid 32 being hinged to the lower end of the casing 30 and adapted to be folded thereon. The rubbish is deposited from the feeding conveyer on to an endless band 34 passing over a magnet roller 36 with extensions 37 the band having plates 38 and fingers. A smoothing or equalizing bar 39 is provided as shown. The magnetic fingers retain the iron pieces in the rubbish and drop them, after passing the magnet extensions 37, on to an inclined plate 43 to deposit them in the receptacle 44. The remaining mass of rubbish containing a large proportion of ashes falls into an angular recess and on to endless bands 48 having spikes. The bands are connected transversely by tubes 49 and pass over rollers 50, 51. Toothed discs 52 on the rollers 51 discharge papers, rags and fine parings of vegetables while ashes fall through the endless bands 48 on to perforated sheets 53, 54 which guide them to compartment 55 while very fine ashes which pass through the perforated sheets 53, 54 the latter of which is reciprocated, fall on to the plate 56 and are guided into the compartment 57. Rubbish such as broken porcelain, stones, bottles, apples, &c., which fall on the bands 48 and are not picked up by the teeth thereof, is admitted, by a plate or door 46 intermittently opened by means of links and levers 61, 62 and a striker 60 on the feeding conveyer, on to a spiked roller 64 which throws it into compartment 65 or by means of another oscillating door 63 into compartment 55. The discs 52 detach the paper, rags, and parings of vegetables, from the bands 48 causing them to be engaged by another roller 66 having double teeth 67 and carrying them to a brush 68 which detaches the paper and allows the rags to pass, the parings falling in the direction of the arrow 74 to an endless band 75 from which they are detached by a comb 76 and fall into compartment 77. Rubbish not picked up by the band 75 falls into the compartment 79, and the rags fall into compartment 73. The various mechanisms are driven from the engine shaft through shafts 18, 21 thence by endless driving chains and sprockets. The apparatus may be employed in a stationary position without the vehicle.

Abstract: Refractory composition comprises alumina and 5-70% of mixed crystals of carbides of Groups IV; V and VI.  Preferred carbides are those of molybdenum and tungsten.  0,5-5,0% or iron group metallic alloys are added to the mixed crystals whilst they are being ground, forming a metallic film on the carbides which facilitates their subsequent sintering.  Temporary organic binder are added to assist in moulding shapes which may be presintered, before final sintering in a reducing gas whilst packed in corundum.
