Title: Improvements connected with the catapulting of aircraft
IPC: B64F1/06
Filed: 1938-07-22
Abstract: 517,331. Launching aircraft; drag anchors. SANDOR, N. July 22, 1938, Nos. 21853/38 and 6205/39. [Classes 4 and 114] A catapulting system for aircraft comprises a moving body which imparts an initial speed or acceleration to the aircraft, the kinetic energy of the moving body in conjunction with a resistance being then utilized to impart an additional substantially constant acceleration to the aircraft until take-off speed is reached. In the form shown in Fig. 1, an aircraft 15 is mounted on a carriage 13 adapted to run along the top of a car 2 which runs on rails 1. The car 2 is driven by motors, which may be carried on an auxiliary vehicle, or by the propellers of the aircraft itself. Upon the car 2 attaining a suitable speed, a body 19 is caused to apply brakes to rails and, being thus retarded, accelerate the carriage 13 relative to the car 2 by means of cables 16 and 21 attached to the body 19. The car 2 may be composed of a plurality of bogie trucks and be provided with an upper runway on which the carriage 13 is mounted, this runway being engaged by horizontally and vertically disposed rollers on the carriage. Hydraulic buffers 49 and 50 are provided to arrest the carriage 13 and the body 19. A separate track may be provided at each side of the rails 1 for the aircraft wheels to run on. For reloading purposes a cradle supporting the aircraft to be launched is provided with a base member adapted to engage in a groove in the carriage 13 whereby an empty cradle may be displaced from the carriage and replaced by a fresh cradle supporting an aircraft. In another form, Fig. 9, an aircraft 15 is launched from the deck of a moving aircraft carrier. The aircraft is drawn along the deck by a cable 16a passing round a drum 17a which is driven by a smaller drum 13a over which passes a cable 21a connected with the drogue 19a, which is dropped into the sea at the desired moment. In another form, Fig. 10 (not shown) a seaplane is towed by a ship through a small boat which carries drums 17a and 18a and from which the drogue is thrown overboard at the desired moment. The drogue described is fitted with a resistance-presenting surface 67, Fig. 11, the position of which is controlled by a servomotor 63 in dependence on the tension applied to the cable 21a towing the drogue. As a spring 57 is compressed by the tension in 'the cable a rack and pinion 58, 59 actuates a valve 61 to control the flow past the servomotor. The cable may be attached to another vessel or to a point ashore instead of to the drogue.
Patent GB-316665-A (GB)
Title: Improvements in and relating to sewing machines
IPC: D05B63/00
Filed: 1929-07-17
Abstract: 316,665. Union Special Machine Co., (Assignees of Christensen, U. V., Rubel, C. F., and Zeier, F. F.). Aug. 2, 1928, [Convention date]. Chain-stitching and double-loop stitching. - A sewing-machine with oscillating loopers has a continuously rotating thread controller with thread guides and controlling elements corresponding in number to the number of looper threads. The invention is illustrated as applied to a machine with three under threads l, l<1>, l<2>, each passing through a tensioning device 4 into a hole 6, 6<1>, 6<2> in a plate 5 and thence to the controller. The controller comprises a hub 9 fixed to the main shaft 3 between discs 7, 8. Each thread engages its own particular part of the controller and passes through notches in a plate 34 to a guide 39 and thence to the three loopers 42 at the end of the arm 40, Fig. 18. The construction of the controller 9 enables each thread to be controlled simultaneously with the difference of degree necessary for compensating for the distance of the looper from the point of emergence of the threads from the arm 40. When the loopers 42 are in their most forward position, the threads lie across the controller in the notches 20, Fig. 13. As the loopers retreat, the controller turns to bring the faces 12, 12<1>, 12<2> into contact with the threads, Fig. 15, to tension the threads. When the loopers are well into the thread triangle, inclined faces 25 on tongues 24, 24<1>, 24<2> on the plate 21 crowd the threads into the recesses 13, releasing the tension and providing enough slack for the loopers to complete the retreating stroke. At this point, the threads lie along the flat side of the controller, Fig. 19, and as the loopers advance again the threads are kept taut by being engaged by the stepped faces 18, 18<1>, 18<2> of the part 19. These steps are necessary owing to the difference of the distance of the loopers from the thread-guiding passage 43 to the arm 40, Fig. 18.

Title: Process for the production of blue pigments
IPC: A61D1/14
Filed: 1936-08-10
Abstract: Blue pigments are prepared by treating a manganese green produced by heating a mixture comprising a manganese compound, a substratum consisting of or containing barium sulphate, and barium nitrate, with an acid in the presence of a reducing agent.  If, in the production of the manganese green, the mixture of originating materials is heated for a period insufficient to convert into oxide all the nitrite formed from the barium nitrate, the presence of this nitrite is sufficient to exert an adequate reducing action during the acid treatment.  Specified reducing agents are sodium and barium nitrites, hydrogen peroxide, barium peroxide, perborates, sulphur dioxide, sulphites and stannous chloride.  The frit of manganese green may be suspended in water before treatment with acid and reducing agent. Specification 1729/64, [Class 95], is referred to.

Abstract: 501,716. Control of D.C. motors. RHEINMETALL - BORSIG AKT. - GES., and GIETMANN, A. July 25, 1938, No. 22020. [Class 38 (iii)] Varying E.M.F.-A system of the Ward- Leonard type, applicable especially to motors effecting adjusting movements of guns, in which the generator is excited by a control exciter operated manually at varying speeds, comprises means varying the field of the control exciter so that the relationship between the exciter voltage and speed is non-linear, and increments of voltage produced by equal increases of speed become greater as the speed increases. The exciter A, Fig. 1, has a field winding a1 of constant energization, and a field a2 energized in accordance with exciter speed from an auxiliary exciter B driven with the exciter A, and having a constant field b. The field b of the exciter B may be energized from a second auxiliary exciter driven with the exciter A and having a constant field. Shunt or series fields may be provided on the exciters to compensate for the resistance voltage drop. In a modification the field al of the exciter A is constantly energized and the field a2 energized by the exciter voltage. In a further modification, Fig. 4, the exciter field a2 is supplied from the exciter B which is driven with the exciter A and has two field windings. One winding bl is constantly energized, and the other b2 is energized from the exciter A. The fields produced by the windings b1, b2 are in opposition and at low speeds the field a2 weakens the field al, while at higher speeds the field a2, reverses and assists the field a1. The relationship between exciter voltage and speed for each of the arrangements described, is explained in the Specification with reference to Figs. 1a, 2a, 3a and 4a (not shown).

Title: Improvements in and relating to catalysts and their preparation
Inventor: ROBINSON JOHN
IPC: C10G11/04
Filed: 1951-09-24
Abstract: Phthalic anhydride is produced by oxidation of naphthalene by the use of catalysts comprising a vanadium oxide and a potassium compound on silica gel.  Preferred proportions (expressed as weight percentages of V2O5 and K2O) for this purpose are: vanadium, 9-11 per cent.; potassium, 16-20 per cent. Fluidized technique may be used.ALSO:A catalyst comprising a vanadium oxide and a potassium compound on silica gel is prepared by a process comprising slowly adding a potassium silicate solution to dilute (e.g. 10 per cent. or 15 per cent.) sulphuric acid whilst agitating, mixing the so-formed silica sol with a solution of a soluble vanadium compound such as vanadyl sulphate, chloride or oxalate, or ammonium vanadate whilst agitating, coprecipitating silica and an insoluble vanadium compound (e.g. by means of aqueous ammonia) whilst agitating, drying and grinding the filtered or unfiltered product.  This product may be calcined, e.g. in fluidized suspension.  When adding the potassium silicate solution the pH should not rise above 4 and the ammonia is preferably added until a pH of about 6.5 is reached, after which agitation is continued until a pH of 8-8.5 is obtained.  The potassium silicate and ammonia solutions are preferably added as spray or as fine jets. In the finished catalyst the optimum percentage of potassium (as K2O) to vanadium (as V2O5) is believed to be about 2; compositions of 7-12 per cent.  V2O5, 12-22 per cent. K2O, and 40-55 per cent. SiO2, and for the purpose of oxidizing naphthaline to phthalic anhydride, of 9-11 per cent. V2O5 and 16-20 per cent. K2O are preferred.  The oxidation of sulphur dioxide is also referred to.

Title: Improvements in or relating to the manufacture of extruded palstic tube or film
Inventor: CLARKE DERRICK STUART
IPC: B29C48/10
Filed: 1966-11-12
Abstract: 1,202,359. Films. GENERAL ENG. CO. (RADCLIFFE) Ltd. 10 Nov., 1967 [12 Nov., 1966; 16 May, 1967], Nos. 50820/66 and 22602/67. Heading B5B. In an apparatus for the manufacture of extruded plastic tube or film the tube or film 10 is drawn upwards by the take-off rollers 11, the platform 12 in which rollers 11 are mounted being given an oscillatory rotation which produces the desired effect of eliminating any lineal fault in the film by displacement of such fault so that it is no longer lineal when wound up. So that such winding or reeling can be effected without rotating it together with the platform 12, the film passes over a roller 14 parallel to the nip rollers 11 and is then re-oriented through 90 degrees by means of the inclined turner bar 15 and one of the rollers 16 so that it is on edge, and is re-oriented for the second time after passing between the rollers 17 and over the roller 18 by the inclined turner bar 19 to pass down to the winding reel 20. The oscillation of platform 12 is only limited by possible interference with the inclined turner bar 15, but this can be obviated by mounting a plurality of guide rollers, three of which are shown dotted at 21, similar to one of the rollers 16 arranged around the periphery of platform 12 so that the the flattened film 10a will lie on the outside of such rollers. In this way oscillatory rotation of the platform may extend to nearly 360 degrees before winding up could interfere with the passage of the film (Figs. 2 and 3, not reproduced). Fig. 4 shows modified guide means for turning the plastics tube comprising a perforate tubular stationary guide bar 21a arranged to be supplied with air under pressure to be used in place of the guide means 15 and 19 of the construction shown in Fig. 1 and indicated in Fig. 1 by broken lines. The guide bar is bent at 22 to an obtuse angle of 135 degrees, and the end of the inclined portion is fitted with a closure plug 23. In the length of the inclined portion are a plurality of radially directed holes 24 which as can be seen from Fig. 5 (not reproduced) are located at points disposed at 45 degrees relative to the plane of movement of the extruded plastic tube or film. In operation it is found that when air at suitable pressure is supplied from a blower 25 to the open end of the guide bar 21a to pass out through the series of holes 24 it forms an air cushion between the plastic tube or film and the adjacent surface of the bar so that physical contact with the bar is prevented. In a modification, not shown, a groove or grooves may be formed on the periphery of the guide bar so arranged as to spread the air on to the plastic tube or film as it passes out through the holes 24, so as better to ensure a continuous air cushion between the plastic tube or film and the adjacent surface of the bar.
