Title: Producing a support for a photographic material
IPC: C08J7/02
Filed: 1973-04-24
Abstract: 1400891 Photographic film support FUJI PHOTO FILM CO Ltd 24 April 1973 [21 April 1972] 19335/73 Heading G2C [Also in Division B5] A base for a photographic film comprises a styrene polymer film containing solute pigment particles which has been treated on one side by a liquid swelling agent and on the other by a mixture of a more powerful swelling agent and one less powerful than the first. Combinations of suitable agents are given. The preferred pigment is titanium dioxide; calcium carbonate may also be present. The tendency of the film to curl towards the surface treated with the mixture increases with the proportion of the stronger swelling agent in the mixture. This affords control over the degree of curling. Further, the surface treated with the mixture is roughened to an extent at which it will accept pencil marks. In Example 1 a treated film is coated with an emulsion comprising silver chlorobromide, gelatine, formalin, saponin and water. After drying, the photographic material obtained showed no tendency to curl.

Filed: 1971-06-08
Abstract: 1300502 Fuel elements COMMISSARIAT A L'ENERGIE ATOMIQUE 8 June 1971 [19 June 1970] 19443/71 Heading G6C A nuclear fuel pin for a fast reactor comprises a stainless steel can 12, 14 closed by end plugs 18, 20, containing a column 34 of pellets of fissile material (e.g. UO 2  and/or PuO 2 ), and fitted with a helically wound spacer wire 21, the extremities of which are attached to the end plugs, e.g. by welding, as indicated at 29, the external diameter of the can section 12 containing the fissile material being slightly less than that of the terminal portions which comprise the end plugs, the length of each terminal portion being at least equal to one-half the winding pitch of the spacer. In the particular embodiment illustrated, the fuel pin also contains a column 26 of pellets of fertile material (e.g. natural or depleted UO 2 ). The two sections 12, 14 of the cam are connected by means of an intermediate plug 16. The fuel pin is intended to be employed in a fast reactor with an upward flow of liquid sodium and within the can, starting from the bottom plug 20, are a fission gas collection space 22, a distance-piece 24 forcibly fitted in the can section 14, the column 26 of pellets of fertile material, supported on the distance-piece 24 by means of a baffle component 28, and a retaining member 30 serving to maintain the column 26 applied against the baffle component 28 and separating the column 26 from a space 15 for the expansion of the fertile material. The column 34 of pellets of fissile material is supported, in a similar manner to the column 26, above the intermediate plug 16 and within the can section 12. On either side of the column 34 are interposed pellets 11, 13 of natural UO 2 . The can section 14 which contains the fertile material and the fission gas collection space 22 has an external diameter equal to that of the end plugs 18, 20 and slightly larger than that of the can section 12 which contains the fissile material. The intermediate plug 16 has a central portion equal in external diameter to the can section 14 and two terminal portions of different external diameter, and is joined to the can sections by welding. Spacing between adjacent fuel pins of the same fuel cluster is determined by the portions of the spacer wire 21 carried by the plugs 16, 18 and 20 and by the can section 14. The clearances at the level of the fissile material may be taken up by swelling of the stainless steel can due to neutron irradiation. The invention may also apply to a fuel pin consisting of two columns of fertile material both located on one side of the column of fissile material.

Title: Improvements in or relating to reversing propeller control
IPC: B64C11/42
Filed: 1944-10-11
Abstract: 605,778. Fluid-pressure servomotor-control systems. UNITED AIRCRAFT CORPORATION. Oct. 11, 1944, No. 19625. Convention date, Jan. 10. [Class 135] In a governor-controlled propeller pitchchanging mechanism, the governor is adapted to control the pitch angle in both forward and reverse pitch positions of the propeller, means being provided to reverse the action of the governor as the propeller passes through the zero pitch position. Fig. 2 shows a reversible pitch propeller in which a fluid-pressure motor is contained within the hub 10 for actuating the propeller blade and is controlled by a port 24 of a follow-up valve (not shown). Movement is imparted to the port 24 through longitudinal movement of a rod 12 which rotates a sleeve 14 with an inclined slot 22 engaging a fixed pin 20. The rod 12 is shown also in Fig. 1 and is actuated against springs 28 by pressure fluid supplied to a piston 26 under control of a governor 42 driven from the engine through a gear 44. The governor fly-weights 46 actuate a valve sleeve 47 which co-operates with an adjustable piston member 60 to control the supply of pressure fluid from a pump 50 to either of conduits 70 or 80 leading to the servomotor 25 and to exhaust the other to a drain sump 74. The conduits 70 and 80 are further controlled by a valve member 90 secured to the piston 26 so that for the range of forward pitch positions the conduit 70 is Open through a conduit 84 to the servomotor, while for the range of reverse pitch positions the conduit 80 is open. This results in a reversal of the action of the governor through the zero pitch position. Solenoid-operated valves A, B and C are provided under control of a switch 92 to effect the change from forward to reverse pitch and vice versa. To change from forward to reverse pitch solenoids A and B are operated to close conduit 84 and open a pressure conduit 54 direct to the servomotor, a stop 38 normally limiting the pitch movement also being withdrawn by a solenoid 40. When the propeller has passed the zero pitch position, the governor 42 takes control on release of switch 92. To return to forward pitch again, solenoids A and C are operated, disconnecting the governor and releasing the pressure in the servomotor to a drain conduit 106. In an alternative arrangement, Fig. 5, the valve 90 is separate from the piston of the servomotor, but is actuated by a solenoid 110 which is energized when a switch 112 is actuated by a cam 113 secured to the rod 12.

Abstract: 422,702. Control of motors. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin) July 11, 1933, No. 19651. Convention date, July 11, 1932. [Class 38 (iii)] Travelling between predetermined limits.-A remote control system for an electric motor operating between limits comprises control switches 1, 2, a single control circuit 5, and relays 9, 10, corresponding to each direction of the motor, the relays 9, 10, in operating, closing contacts 17 whereby they are maintained over circuits which are independent of the control circuit, but which are interrupted by limit switches 7, 8 when the motor reaches either of its limits. During operation of the motor in either direction, it may be stopped by closing a control switch 1 or 2 corresponding to reverse movement. The closure of the control switch completes a short-circuit for the coil of the operative relay over the control circuit 5, anda switch 11 driven by the motor. The consequent opening of the operative relay closes over contacts 16, and a switch 12 a circuit for the coil of the reverse relay, so that the motor reverses, and when it reaches its limit it is stopped by the opening of the reverse relay by the switch 12, which is also driven by the motor. In a modification, Fig. 2, (not shown), the motor is stopped and reversed to its limit during its movement in either direction by operation of the reverse control switch 1, or 2, which energizes the reverse relay over a switch driven by the motor. The closing of the reverse relay interrupts the maintaining circuit of the previously operated relay. The main contacts of the relays in this arrangement may be locked together or time delayed.

Title: Process for removing sulphur dioxide from waste gaseous effluents
IPC: B01D53/52
Filed: 1969-04-17
Abstract: 1,244,905. Removal of sulphur dioxide from effuent gas. ONTARIO RESEARCH FOUNDATION. 17 April, 1969 [18 April, 1968], No. 19769/69. Heading C1A. Sulphur dioxide is removed from effluent gas by combusting a hydrocarbon fuel to form a combustion products stream having a temperature of 500-900‹ C., feeding hydrocarbon fuel, steam and sulphur into the combustion products stream, thus generating a reducing gas comprising H 2 S, reacting the reducing gas with the effluent gas in the presence of a catalyst at a temperature of at least 50‹ C., whereby the sulphur dioxide is at least partially reduced to sulphur as follows: The hydrocarbon fuel is natural gas, naphtha or residual oil and is reacted with steam and sulphur in the presence of a catalyst. The reducing gas may be obtained in a single step or in two steps, the first step involving reacting hydrocarbon fuel with sulphur to produce carbon disulphide and the second step involving hydrolysing the carbon disulphide with steam. The reducing gas thus comprises H 2 S or mixtures of H 2 S with carbonyl sulphide and/or carbon disulphide. The reducing gas may be contacted with the effluent gas in a low temperature reaction between 50‹ and 150‹ C. or a high temperature reaction between 250‹ and 400‹ C., in the presence of a catalyst, or two separate catalyst beds, one at a high temperature and the other at a low temperature. In the low temperature reaction sulphur is deposited on the catalyst and is removed and the catalyst regenerated by passage of the reducing gas therethrough at 250-450‹ C., condensed and at least partially reacted with hydrocarbon and steam to form reducing gas. In the high temperature reaction, sulphur is produced in the form of a vapour which again may be condensed and reacted with hydrocarbon, thus the process may be operated continuously. Many different catalysts may be employed,e.g. cobalt molybdate on alumina, iron oxide or alumina, noble metals,e.g. Pd, Pt, Rh on catalyst supports. Referred catalysts are activated alumina or bauxite. Reference has been directed by the Comptroller to Specifications 1,097,306 and 1,132,846.

Title: Process for the production of foils from solutions of cellulose compounds, gelatine and the like
IPC: B29C48/08
Filed: 1930-07-01
Abstract: <PICT:0345179/IV/1> Foils and films are obtained from solutions of cellulose compounds, gelatine and like substances with the aid of a travelling pouring base partly immersed in a coagulating bath, the process being carried out in such manner that the solution is allowed to coagulate only to a certain depth, and the coagulated layer is stripped off, leaving a residual uncoagulated layer on the pouring base.  The thickness of the foil produced is controlled by the speed of travel of the pouring base, the temperature of the solution, the temperature and concentration of the coagulating bath, the thickness of solution applied to the base, and the point at which stripping takes place.  As shown in the Figure, solution such as viscose flows from the slit of a pouring device 1 to form a layer of thickness a on a drum 2 which rotates in the direction of the arrow 3 and dips into a coagulating bath 4.  When the layer of solution has coagulated to a depth b, the coagulated layer is stripped by the roll 5 and is led as a freely suspended foil 6 over the guiderolls 7, 8 out of the coagulating bath to further treatment baths.  There remains on the drum 2 an uncoagulated residual layer of thickness c.  Upon this layer fresh viscose solution is applied by the pouring device 1. Instead of a drum an endless band may be employed as pouring base.
