Title: Improvements in and relating to the manufacture of artificial silk
IPC: D01D5/06
Filed: 1936-07-31
Abstract: <PICT:0459353/IV/1> <PICT:0459353/IV/2> Artificial silk particularly that from cuprammonium cellulose solution, is obtained by extruding the spinning solution through comparatively narrow spinneret holes within a bath containing a strongly acting precipitating liquid, a tubular member open at each end being arranged within the bath concentrically about the extruded filaments, and fresh precipitating liquid being forced by means of nozzles through the tubular member from the spinneret head side.  The liquid stream issuing from the bath nozzles sets up intensive circulation of the precipitating liquid through the tubular member, into the open bath, and back into the tubular member.  The tubular member may be cylindrical or conical. Stretching of the filaments is produced if the tube tapers in the direction of filament travel, owing to the acceleration of the flow of liquid.  If the tube widens in the direction of the filament travel, stretching occurs owing to the increased friction of the liquid on the filaments.  As shown in Fig. 1, the spinning pipe 1 with nozzle 2 can be swung into the spinning bath 3.  Fresh precipitating liquid enters through nozzles 6 arranged in a ring around the spinning nozzle and is forced through the cone 7 together with the filaments 8 and through outlet 9.  The filaments pass around the idly running roller 10 dipping into the coagulating liquid and capable of being readily moved by the filaments.  The roller 10 is mounted in overhanging manner and is capable of being swung into position.  The conical member is provided with a bulge 11 enabling it to be disposed securely on a yoke 12, 13.  The proportion of fresh precipitating liquid issuing from the nozzles 6 to the quantity of already used liquid flowing into the conical member can be adjusted by varying the annular clearance between the end of the cone and the wall of the bath. If desired the roller 10 may be positively driven. As shown in Fig. 2, the spinning nozzle 21 is surrounded by the vertical conical member 23 provided with a ring 24 which can be swung about the pin 25.  Fresh precipitating liquid is forced into the chamber 27, then through nozzles 28 and then through the conical tube 23. The liquid flows over the top edge of the tube into the spinning bath 26 and then again into the lower end of the tube.  Excess liquid passes to the overflow device 29.

Patent GB-805695-A (GB)
Title: Improvements in or relating to methods of and systems for supplying fuel for turbojet engines
IPC: F02C9/16
Filed: 1955-07-25
Abstract: 805,695. Gas-turbine plant. SZYDLOWSKI, J. July 25, 1955 [Aug. 4, 1954], No. 21486/55. Class 110 (3). The acceleration of a turbo-jet engine under the action of a rise in the fuel supply pressure, causing an increase in the pressure at the inlet of the engine feed nozzle is controlled so that with any pressure rise in the fuel supply the resulting fuel pressure at the engine feed nozzle is reduced down to a value which is not less than that existing at the nozzle inlet before the pressure rise occurs, while the fuel flow to the engine is maintained at a rate not lower than that existing before the pressure rise occurs, then the inlet pressure is allowed to rise gradually to a value corresponding to the pressure rise. The gas-turbine jet-propulsion engine 20, Fig. 2, is fed with fuel by a pump 21 through a feed line 22 and a nozzle 27. A by-pass 23 with an adjustable relief valve 24 controls the pressure in the feed line 22. The fuel supply to the engine is regulated by a valve 26 controlled by a speed governor 25, the setting of which is controlled by the throttle lever. A valve 28 controlled by means responsive to altitude 29 is also provided. A device 30 is also provided to limit the rate of acceleration. The device 30, Fig. 2, comprises a container 1 divided into two compartments 2, 3 by a resilient diaphragm 4 which is connected to a valve 9 in the fuel feed line 10. The diaphragm 4 is loaded by a spring 5 secured to a wall 6 which is perforated at 7. A sealed resilient bladder 11 filled with air is located in the chamber 2. Chambers 2 and 3 are connected together by a pipe 14 which contains a variable area orifice 15 between the connections to the chambers. The area of this orifice is varied by bellows 16 which are responsive to the total pressure, i.e. the static pressure plus the pressure due to the forward speed of the aircraft. When the pilot wishes to accelerate the engine he moves the throttle lever in the opening direction. The resulting increase in pressure in the fuel line passes through the pipe 13 and moves the diaphragm 4 to close the valve 9 and so decrease the pressure. At the same time, the pressure in the chamber 2 increases at a slower rate due to the presence of the orifice 15. After a predetermined time, the pressures in chambers 2 and 3 are balanced and the valve 9 moved to its open position by the spring 5. The area of the orifice 15 may be adjustable only by a manual control 19. The bladder 11 may be replaced by a spring-loaded piston. The valve 9 may be attached to or resiliently urged against the diaphragm 4. Specifications 693,217 and 693,218 are referred to.

Abstract: 566,281. Gas manufacture. HENE, E., and TRINIDAD LEASEHOLDS, Ltd. July 25, 1939, No. 21656. [Class 55 (ii)] [Also in Group III] Distillates of the nature of gas oil are obtained from heavy oil and tarry residues with a minimum production of coke, gasoline and gas by spraying or dripping the oil on to the surface of a body composed of lumps of porous material, e.g. coke heated to 400-600‹ C., the rate of feed of the oil and size of the lumps being such that only a thin film of oil is formed on each of the lumps contacted by the oil at any given instant of time and the vapours formed being rapidly withdrawn and condensed. The contact body consists preferably of a bed about one inch thick of lumps of coke # -¥ inches in diameter which increase in size owing to the carbon deposited thereon. Gases or vapours, e.g. ethylene, may be passed through the bed to carry off rapidly the vapours which may then be cracked. Asphaltic oils may be diluted with lighter oils. A reduced Trinidad mixed base crude oil (initial boiling point 300‹ C.) is sprayed at the rate of 4 c.c. a minute on to a bed of coke heated to 480‹ C. while carbon dioxide is passed over the surface of the coke. An oil, 3 per cent only of which boils below 200‹ C. is obtained together with 2 per cent of gas and 6 per cent of coke. U.S.A. Specification 2,114,416 is referred to.

Title: Improvements in or relating to electric couplings of electrically propelled trains
IPC: B61G5/10
Filed: 1929-07-18
Abstract: 336,660. General Electric Co., Ltd., Croft, E. H., and Price, A. C. July 18, 1929. S w i t c h i n g systems. - The jumper coupling of both the train line and an auxiliary control line are locked in a closed position while the train line terminals are energized. The train lines 4, 5 are connected to the main supply through switches 24, 26 that are closed by coils 25, 27 the circuit of which is complete through leads 10, 11 in the jumper at the left-hand end of the coach, and through a link 20 so that the switches can be closed only when the jumper head is inserted in the corresponding dummy receptacle at the end of the coach thus enclosing the terminals of the leads 8, 9 passing through the same jumper. At the opposite end of the coach the terminals 12, 13 are energized only when switches 21, 22 are closed, this being effected by a coil 29 in a circuit 41, 42 that is closed by a switch 31 closed by a coil 30 in the lead which is in the same circuit as the coils 25, 27. This circuit is energized from low tension lines 35, 36 through a fuse 40, jumper leads 10 between the coaches, and a switch 32 in the position shown engaging a contact 34. The switches 21, 22 of the coach 2 will not be closed since the coil 30 of that coach is not energized. If, however, another coach is attached the switch 32 will be manually operated to engage the contact 33, a similar switch 32 being provided on the added coach. The locking of the jumper heads is effected by the closing of the switches 21, 22 as shown in Fig. 4. The coil 23 lifts a plunger 132 carrying a cross-bar 133 which by means of an insulating pillar 165 operates a switch arm 150 pivoted at 152 to the pillar and to an arm 156 pivoted at 159, a compression spring 158 being located between projections 155, 157 on the arm 150 and lever 156 respectively. The contact 142 is thus lifted into engagement with the contact 141 and the switch closed. At the same time a push-rod 114 is lifted by the plunger 132 and operates a lever 113 that carries a catch 112 to engage the casing 63 of the jumper head and lock it in the receptacle 56. Arcing horns 143, 144 attached to the contacts 141, 142 are arranged in an arcing chamber 167 at each side off which are blowout cheeks 168 attached to iron limbs 174 that pivot about the axis of the blow-out coil 149. The jumper cable 87 is secured to the head by a segmental tapered collar 84 clamped by a sleeve 94 and nut 83. The cable 90 is similarly attached. A projection on the cover 93 engages the jumper head 56 under the action of a spring 105 and holds it in place when the locking lever 113 is disengaged. The supply of current to the coils 25, 27 is controlled by switches 29 arranged as shown in Fig. 3, each switch having a pair of coupled arms 48, 49, the arm 49 when moved to open the circuit through one coil engages a contact 50 that brings a resistance 28 into circuit and so maintains the current at the value necessary to operate the relay coils 30.

Title: Process for the removal of carbon from the surface of elements of iron or iron alloys
IPC: C21D3/04
Filed: 1930-07-22
Abstract: Carbon is removed from the surface of elements composed of iron or iron alloys by heating the elements at a temperature below the melting point of the metal or alloy, e.g. between 700 DEG  and 1200 DEG  C., in a fused salt bath containing sodium chloride and barium chloride and substantially free from carbon compounds.  The bath may consist of 15 per cent sodium chloride and 85 per cent barium chloride.  The process is particularly applicable to the iron alloys containing nickel and cobalt described in Specification 357,665 for use as lead-in conductors to be sealed into boro-silicate glass or lead glass in vacuum discharge apparatus as described in Specification 358,934.  The Specification as open to inspection under Sect. 91 (3) (a) describes other means by which the formed elements may have a carbon-free surface which consist of (a) heating the element in an atmosphere of hydrogen, (b) forming the element of iron or iron alloy which has been treated in the molten state either by passing hydrogen through it or by heating in contact with refractory oxides in a vacuum, or (c) by coating the surface of the element electrolytically with a thin layer of chromium, copper, or "other carbon-free metal."  This subject-matter does not appear in the Specification as accepted.
