Abstract: 222,075. Shirlow, A. E., McDiarmid, T. B., and Patterson, J. Sept. 23, 1923, [Convention date]. Kinematograph arpparatus. - In apparatus for winding films from the circumference towards the centre of a spool so as to avoid the necessity for subsequent rewinding, the winding means are provided with a device in the form of an endless belt which presses against the inner convolutions of the film as it is being wound and is arranged to recede towards the centre of the apparatus as the winding proceeds. The apparatus comprises a casing 1 within which is a revoluble disc 4 having a flange 5. Supported at the centre of the disc is a member 8 consisting of a number of discs secured together and formed with slots in which arms 10 - - 13 are 'adapted to slide. The movements of the arms can be adjustably restrained by pads carried by screws 32. The member 8 is secured to the casing 1 by slotted arms 6, 7 engaged by thumb-screws 60, 61. The arms 10 - - 13 are provided at their outer ends with rollers 19 forming guides for the endless belt 20 which also passes through a guide 28 on an arm 25 pivoted to the member 8, a spring 31 being provided around the pivot to urge the arm 25 in a clockwise direction and thus maintain the tension of the belt as the film is wound. The belt is driven by a roller 33 around which it passes, the roller being carried by an arm 34 pivoted around a spindle 35 and being driven by sprockets 37, 38 and a chain 39 from the said spindle. The arm 34 is connected by a cord 40 to a weight slidable within a tube 41. The spindle 35 is driven from a spindle 49 by a chain 51 and bevel gears 55, 56, the spindle 49 being provided with a friction clutch consisting of a driving pulley 57<a> and a pulley 57 secured to the spindle, the faces of the pulleys being pressed into engagement by a spring 58. The film entering the casing 1 passes between a pair of rollers 44, 45 mounted in a frame 46 which is attached by pivots 46a, 46b, to a frame 47 secured to the casing. The leading end of the film is gripped within the casing by a flexible split band 48. When the film is completely wound the member 8 is removed by releasing the arms 6, 7 and the film is mounted on a centre piece 62, Fig. 5, provided with a number of radially-adjustable arms 64 having thereon curved members 65 adapted to contact with the innermost convolution of the film.

Title: Solid electrolytic capacitors and their method of manufacture
IPC: H01G9/02
Filed: 1954-03-05
Abstract: 747,051. Capacitors; anodic oxidation of tantalum. WESTERN ELECTRIC CO., Inc. March 5, 1954 [April 2, 1953], No. 6505/54. Classes 37 and 41. A capacitor comprises a porous body formed of compressed adherent particles of an anodizable metal, a dielectric film produced electrolitically (i.e. by anodization) on the surfaces of the particles, a layer of semi-conductive material deposited on the dielectric film and an electrically conducting covering layer deposited on the semi-conductive layer. A solid wire of the anodizable metal, e.g. tantalum, is embedded within the porous body which serves as one electrode of the capacitor, the other electrode of which is constituted by the conducting layer, e.g. of graphite. A sprayed-on or melted-on metal casing surrounds the capacitor making contact with the conducting layer and leads are attached to this casing and to the wire of the anodizable metal. The capacitor is prepared by the process shown in the Figure. Particles of tantalum are compressed and sintered to form a rigid porous mass, preferably of cylindrical form, a solid wire of tantalum being embedded at the same time in the mass. The porous mass is then immersed in an elec trolyte which may be either an aqueous solution or a fused salt and current passed to form an oxide film on the tantalum particles. The porous body is then immersed in a solution of manganous nitrate and then heated to convert the nitrate to manganese dioxide which provides the semi-conductive layer. Anodization and deposition of fresh semi-conductor is then repeated in order to heal any imperfections in the oxide film and reduce leakage current in the capacitor to a low value. The body is then immersed in an aqueous suspension of graphite and is then air-dried or heated to provide an outer conducting layer to the coated particles. Leads are attached and the metal coating is then sprayed or melted on. Finally the capacitor may be given a coating of lacquer. In place of tantalum, other suitable anodizable metals are aluminium, tungsten, columbium, hafnium, titanium and zirconium. The electrolyte is preferably a fused salt mixture such as equal parts by weight of sodium nitrate and sodium nitrite at 250‹ C., 66 per cent potassium nitrate and 34 per cent lithium nitrate by weight, or 54 per cent potassium nitrate, 30 per cent lithium nitrate and 16 per cent sodium nitrate. The semi-conductive layer; which is thought to act in a manner similar to that of the electrolyte in an electrolytic capacitor to heal flaws in the oxide layer by ionic migration, may alternatively comprise the higher oxides of lead or nickel.

The end of the coil c may open into the vapour space of the vessel so that steam, air, &c. after passage through the coil may assist in carrying oil vapours from the vessel.
Patent GB-885497-A (GB)
Title: Improvements in or relating to steam turbine installations
IPC: F01D19/02
Filed: 1958-03-03
Abstract: 885,497. Correspondence control systems. SIEMENS-SCHUCKERTWERKE A.G. March 3, 1958 [March 2, 1957], No. 6818/58. Class 40 (1). [Also in Group XXVI] The rate of change of load on a steam turbine is limited to a maximum dependent upon the existing load on the turbine. In the arrangement shown, a manually operable switch 23 can be moved to a position L or position R and cause a motor 22 to open or close the turbine inlet valve. For the two directions of rotation, separate magnetic amplifiers 24, 25 come into effect. These magnetic amplifiers contain premagnetized chokes across which fall a part of the voltage applied to the motor 22. A tap 27 of a potentiometer 28 is adjusted by the motor 22 through a regulator 26 in accordance with the position of the turbine inlet valve or the oil pressure of the turbine regulator. The potentiometer 28, together with a further potentiometer 31 forms a Wheatstone bridge, the feed voltage of which is applied at points 29, 30. The potentiometer 31 has a tap 32 which is set by a motor 33 in such sense that the bridge is always brought into the balanced state after being unbalanced by movement of the tap 27. An amplifier 34A is connected to the output diagonal of the bridge and the control windings of the magnetic amplifiers are connected to it. When a particular positive or negative voltage, corresponding to the maximum rate at which the turbine load may be charged, is exceeded the motor 22 stops due to one of the magnetic amplifiers becoming non-conductive. Different maximum values may be set for sudden load changes in the positive and negative sense. Control in response to variations of live steam temperature may be introduced by inserting into a branch of the bridge a voltage proportional to the temperature. In a modification, Fig. 1. movements of the turbine inlet valve 2 adjust the tapping of a potentiometer 5 in the circuit of a heater 14 heating two bars 14, 1.5 of different heat capacity. The differential heating of the bars during sudden load changes sets a tap 18 of a potentiometer 8. The voltage from the potentiometer 8 is compared with a reference voltage, which is dependent upon the load and pressure and temperature of the live steam in the controller 9. If the voltage applied to the controller exceeds a certain value, the controller 9 adjusts the regulating valve 2 in the opposite sense to that dictated by the load signal. A variable resistance 17 controlled by the turbine inlet temperature may be provided. In a modification, Fig. 2 (not shown), the control device 6 is replaced by a potentiometer having two tappings, one corresponding to the valve position before the controlling action and one to the position after this action. The voltage difference between the tappings is fed into the controller 9.
