Abstract: 363,921. Uniting by fusion. SOC. ANON. DES ATELIERS DE SECHERON, Avenue Blanc, Geneva, Switzerland. March 26, 1931, No. 9244. Convention date, March 27, 1930. [Class 83 (iv).] In a process of metallic arc welding, the coating of the electrode contains besides a mixture of substances which react exothermically, such as a thermo-aluminic mixture, substances which by chemical action under the heat of the arc evolve gases to blow away from the joint the products of the exothermic reaction. The thermo-aluminic mixture may consist of reducing substances such as aluminium, titanium, calcium, silicon, manganese, magnesium, or mixtures thereof, or alloys thereof with iron, nickel, copper, &c., and oxidizing substances such as ferric oxide, manganese dioxide, nickel oxide, chromic oxide, &c., or mixtures thereof for obtaining alloy welds. The gas producing substances may be carbonates such as iron carbonate, manganese carbonate, calcium carbonate, or magnesium carbonate to evolve carbon dioxide, or hydrates or hydrated substances such as hydrates of iron or manganese, or kaolin to evolve steam, or mixtures of carbonates and hydrates. These substances may in part or entirely replace the oxide portion of the thermo-aluminic mixture; e.g. iron carbonate may replace ferric oxide and manganese carbonate may replace manganese dioxide. The gas producing substances after evolving their gases may combine with the alumina or silica produced by the thermo-aluminic reaction to effect a further exothermic reaction by forming aluminates or silicates. A mixture may consist of 50 per cent of aluminium thermit, 15 per cent of silicon thermit, 15 per cent of manganese thermit, 5 per cent of carbonates, 5 per cent of hydrates and 10 per cent of other substances mixed with a binder such as sodium silicate. The other substances may consist of fluxes, or substances for alloying with the weld or mixtures thereof. As examples 5 per cent of ferrochrome and 5 per cent silicic acid may be used, or 5 per cent of ferromolybdenum and 5 per cent of lime, or 10 per cent of borax. The gas-producing substances may be located near the core so as to increase the blast effect by first dipping in a paste thereof and then in a thermo-aluminic mixture.

Patent GB-568703-A (GB)
Title: Improvements in or relating to systems actuated by liquid pressure
IPC: F15B7/10
Filed: 1943-06-11
Abstract: 568,703. Hydraulic transmission of power. BENDIX AVIATION CORPORATION. June 11, 1943, No. 9468. Convention date, Oct. 19, 1942. [Class 69 (ii)] A liquid pressure system, e.g. for controlling an aircraft engine throttle, comprises driving and driven members 18, 38 connected by a liquid link 12, and switch means 44, 46 adapted to actuate compensating means to maintain the liquid. volume constant. Expansion or contraction of the liquid causes the driven member to move in one direction or the other to actuate a microswitch S3 or S2, thereby starting a pump 52 or opening a solenoid - actuated valve 156 or 152, whereby liquid is withdrawn from or added to the system. Adjustment of the liquid volume automatically returns the driven member to its correct position and opens the respective micro-switch, thereby stopping the volume compensating means. The micro-switches are rendered inoperative during normal actuation of the system, through the hand lever 22, by means of a hand-operated switch S1 in the pump or valve circuits. The state of synchronism of the driving and driven members is indicated by a galvanometer 78 and adjustment is effected by moving the driving piston towards one end of its stroke, thus causing liquid to be added to or subtracted from the system, e.g. by means of the manually-actuated slide valve 88, or by means of the solenoid-operated valves 152, 156. The solenoids of these valves are arranged in circuits including pairs of switches S14-S21 so placed as to be actuated by the driving or driven member respectively when it reaches the end of its stroke. This causes the respective circuit to be energized, thereby opening the liquid supply or exhaust valve 156, 152 which remains open until the liquid column is adjusted to its correct length and the other member also reaches the end of its stroke, thereby breaking the circuit and de-energizing the solenoid.

Title: Improvements in heat recovering apparatus for evaporators
IPC: B01D1/06
Filed: 1947-04-10
Abstract: A device for the recovery of waste heat from evaporators is interposed between the evaporator and the discharge chimney for the vapours and comprises a central passage, heat-exchange means arranged between the passage and the <PICT:0640714/III/1> <PICT:0640714/III/2> <PICT:0640714/III/3> external wall of the device, and a baffle fitted with a valve at the end of the passage which permits either the deflection of the vapours through the heat-exchange means or the direct discharge of the vapours from the end of the passage.  The vapours may contain air.  The heat-exchange means may be coils, bundles of tubes or any other type of surface exchanger, or may be a water-atomizing device.  In Fig. 1, the vapours from evaporator a pass through central passage c which is capped by frustocone d provided with valve e.  The frustocone extends downwards as a cylindrical wall f which divides the space between the central passage and the external wall b into annular spaces f1 and f2 in which worms g and h are housed.  Water enters the worms at i, and leaves at j.  If valve e is open, the vapours pass out directly and there is no heat recovery.  But if valve e is closed, the vapours pass through the annular spaces and heat the water in the worms.  A condensate is formed which is withdrawn through pipe k. Uncondensed vapour is discharged by means of fan v.  In Fig. 4, water is atomized directly into the device through perforated tubes q and r.  The hot water mixed with the condensate is removed through pipe k.  The Specification as open to inspection under Sect. 91 describes modified devices such as that shown in Fig. 5 (Cancelled), wherein baffles s and t replace the central flue and frustocone described above.  The condensate is withdrawn through pipe u.  This subject-matter does not appear in the Specification as accepted.

Abstract: 564,243. Valve amplifying circuits. BRITISH THOMSON-HOUSTON CO., Ltd. June 18, 1943, No. 9808. Convention date, June 22, 1942. [Class 40 (v)] In an amplifier operating at very high frequencies, undesirable low input impedance due to degeneration caused by the inductance in the cathode lead and a capacitive of load impedance is avoided by providing further inductance in the cathode lead and connecting the junction of this inductance with the inductance in the cathode lead effectively to the anode through the load. The Figure shows a pentode in which the inductance 17 is compensated by the inductance 18, a blocking condenser 20 connecting the inductance 15 of the load to the junction point. In this way the current flowing in the inductance 18 neutralizes that flowing in 17 and zero voltage exists at the cathode. The ratio between the inductances 17, 18 is that between the capacity across the load to that between the anode and cathode. These capacities, together with inductance 15, form a tuned output circuit. The tapping to the inductances 17, 18 may be made

Abstract: 560,220. Compound compressors. FORD, R. C. June 19, 1943, No. 9920. [Class 8 (i)] [Also in Group III] In evaporators for distilling liquids of the kind in which the vapours evolved are compressed and the heat generated used to distil the liquid, e.g. by passing the compressed vapours through coils immersed in the liquid, the vapours are first compressed in a low pressure cylinder and then further compressed in one or more high pressure cylinders which are preferably formed with annular passages down which the compressed vapours flow and communicate heat to the liquid flowing through annular passages form on the high pressure cylinders. The apparatus shown in Fig. 1 comprises a closed container 50 with removable upper cover 51 and condenser 39. The low pressure cylinder 17 supports and operates the plungers 29 of the high pressure cylinders 26 which are symmetrically mounted on a fixed plate 27 dished to hold the liquid to be distilled. Vapours pass from the cylinder 17 through a pipe 47 to the space 28 above the liquid which is enclosed by a double walled lagged cover 42. The cylinder 17 is reciprocated by a rotatable member 19 concentric therewith and driven by bevel gearing 22 from a shaft 23. The high pressure cylinders compose each an inner part 31, Fig. 4, screwing on to an outer part 32 formed with a passage 33 controlled by a non- return valve 34 and communicating with a passage 35 formed between the parts 31, 32 and leading to a duct 36 connected to a pipe 57 by which the vapours pass to the condenser 39.
