Abstract: 266,718. British Thomson-Houston Co., Ltd.. (Assignees of Connell A. C.). Feb. 23, 1926, [Convention date]. Synchronizing dynamo-electric machines.- Alternating current systems 2, 3 are interconnected by a switch 1 the control winding 4 of which is only energized when the phase difference between the E.M.F's is brought within a predetermined range of values, and the difference between the frequencies is maintained between predetermined maximum and minimum limits. Three induction disc relays 8, 10, 12, are each operated by a pair of shaded pole motors, one of each pair being supplied with the difference of the system voltages and the other with the sum thereof, through potential transformers 13 - - 16. The relay 8 closes its contacts when the difference of frequencies is within a certain limit, the relay 10 when the voltages approach phase coincidence, and the relay 12 opens its contact only when the difference of frequencies is below a certain limit. The disc of the relay 10 has a segment removed so that when one shaded pole motor exerts a torque strong enough to move the disc, the movement thereof strengthens the stronger torque and weakens the weaker torque so as to obtain a quick and positive action.

Abstract: 470,819. Squirting. STEVENS, A. H. (Sparks Processes, Inc.) Feb. 19, 1936, No. 5049. [Class 83 (iv)] Billet-piercing.-In the extrusion of rods or other solid metal shapes a tool or mandrel is forced into the billet, of such a size that it substantially equalizes the inner and outer temperatures of the blank before the extrusion operation. A press wherein the movements of the parts are all hydraulically controlled comprises a container 53 which carries the billet 54 to be extruded. A piercing tool 42 having a reduced end 75 is advanced through the billet, and the plunger 36 is moved to the right, Fig. 5, while the die 68, and the billet and container and the tool 42 are at the same time moved to the left to effect the simultaneous extrusion of a number of rods. The die 68a, Fig. 17, comprises a series of die apertures of square, circular, or other section surrounding a central aperture which receives the end of the tool 42. The residue is severed by a tool 81, Fig. 8, which is secured to the end of the tool 42 by tightening a ring 89, and which carries members 91 to enter the die apertures and break away the extruded rods from the residue, a member 93 entering the central hole in the residue. The parts are located by keys in correct angular relation. The die may be expelled from its holder by an ejector 159 bored for passage of the extruded rods 92, and aligned with a similarly bored guide 79. Billets are delivered to the apparatus by a cradle 73. In a modified press, extrusion is effected indirectly, the ram and container being locked for movement together, and the die advancing through the container. A single rod 92, Fig. 12, may be formed, the tool 42a being disposed so that its end does not enter the die. Flat strip blanks 105, Fig. 20, are produced in apparatus comprising an inner member with radial projections 109, which subdivide the extruding metal. Specification 451,848 is referred to.

Patent GB-481141-A (GB)
Title: Process for the destructive hydrogenation of coal, in particular bituminous coal
IPC: C10G1/06
Filed: 1937-02-23
Abstract: Coals, and in particular bituminous coals, with a carbon content of at least 82 per cent are destructively hydrogenated in continuous operation at temperatures above 400 DEG  C. and under a hydrogen partial pressure not less than p, such that log p=0,063283C-2,809, where C is the percentage of carbon in the moisture- and ash-free coal.  Preferably, a pressure up to 50 atmospheres higher than p is chosen by means of preliminary experiments, such that no further increase in the yield of liquid hydrocarbons is obtained by working above such pressure. Suitable catalysts are zinc compounds or molybdenum compounds or organic compounds of tin.  In an example, bituminous coal with a p  carbon content of 82 per cent is made into a paste with heavy oil produced from the same coal and is mixed with a catalyst of tin oxalate and ammonium chloride.  The mixture is heated with hydrogen at 250 atmospheres up to 460 DEG  C. and then passed through the hydrogenation vessel, the products being cooled and released from pressure.  The conversion of the carbon is 97 per cent, of which 21 per cent consists of gaseous hydrocarbons.  With a hydrogen pressure of 300 atmospheres, the results are almost identical.  At 200 atmospheres, the conversion is 97 per cent, of which 26 per cent is gaseous, and the asphalt content is higher. In a second example bituminous coal with 88 per cent carbon, treated at 600 atmospheres, gives a 96,5 per cent conversion, with 21 per cent gas and 9,5 per cent asphalt in the heavy oil. Similar results are obtained at 700 atmospheres, but at 250-300 atmospheres the conversion is only 90 per cent, the gas is 30 per cent and the heavy oil contains 17 per cent asphalt.
