Title: Improvements in fuel cell control systems
IPC: H01M8/04
Filed: 1959-04-24
Abstract: 857,368. Fuel cells. UNIVERSAL WINDING CO. April 24, 1959 [April 28, 1958], No. 14135/59. Class 53 A fuel cell comprises an oxygen electrode 12 and a hydrogen electrode 14 to which the gases are led from containers 22, 16 through differential flow controls 26, 20. Electrolyte is supplied from a tank 30 through a line 32 and is circulated through the cell. In order to regulate the gas pressures and to maintain a constant pressure difference across each electrode, a control gas for example nitrogen is stored in a container 34 and has access to the tank 30 through a line 36. The electrolyte is thus supplied to the cell under the pressure of the gas in the container 34, for example 600 pounds per square inch. The control gas is also supplied through lines 38, 40 to the controllers 26, 20 one of which is shown in Fig. 3. The control gas is led into the device at 68 and depresses a diaphragm 62 which opens a valve 58 to allow hydrogen or oxygen to enter at 54 and pass out at 56. If the pressure of gas below the diaphragm exceeds the pressure of the control gas by an amount determined by the spring 64, for example 3 pounds per square inch, the valve 58 closes. Both controllers 26, 20 act in the same way so that both gases delivered to the cell through the lines 21, 28 are at a pressure of 3 p.s.i. above the pressure at which the electrolyte is delivered. In a modification only one differential flow control is used, the second control being replaced by a pressure equalizer which ensures that the hydrogen and oxygen are delivered to the cell at the same pressure. The equaliser is similar to the device shown in Fig. 3, but the spring 64 is omitted and the oxygen line is connected to the inlet 68, hydrogen being admitted at 54 and delivered to the cell through the outlet 56.

Title: Improvements in or relating to the manufacture of flat glass
IPC: C03B18/06
Filed: 1957-05-03
Abstract: 893,663. Glass manufacture. PILKINGTON BROS. Ltd., and PILKINGTON, L. A. B. April 22, 1958 [May 3, 1957], No. 14205/57. Class 56. In the manufacture of flat glass, the glass is delivered at a controlled rate to a bath of molten metal and advanced along the surface thereof under thermal conditions which establish a layer of molten glass on the bath, the glass is maintained in molten condition until there is developed on the surface of the bath a buoyant body of stable thickness by permitting the layer of molten glass to flow laterally unhindered to the limit of its free flow under the influence of gravity and surface tension, the buoyant body being then continuously advanced in ribbon form and cooled as it is advanced to permit it to be taken undamaged out of the bath by mechanical means, the surface of the bath of molten metal being protected against the formation of contaminats in the glass. As shown in Figs. 1 and 4, molten glass 11 is poured over the lip 4 of a spout 3 from the melting tank 1 to the bight between casting rolls 6, 7 set at an angle so that the molten glass in the form of a ribbon 23 is projected downwardly and forwardly on to the surface 16 of a bath of molten tin 15. The molten tin 15 is in a tank 12, 13, 14 wide enough to allow lateral spreading of the ribbon 23 to a buoyant body 31 of molten glass, the temperature being regulated in the bath by regulators 29, 30 to give a temperature of about 1,000‹C. adjacent the ribbon 23. A roof structure 17 with adjustable end walls 18 encloses the bath 15 and is divided by tweels 32, 33, 34 into areas which are successively cooled so that at the discharge end, the ribbon 35 formed from the body 31 is sufficiently stiffened to be removed by driven rolls 27, 28 which deliver the ribbon 35 to a tunnel lehr. A protective atmosphere is maintained in the roof structure 17 and over the rolls 6, 7, under a cover 25 by ducting 39 connected by branches 40 to headers 41 supplied gas, such as coal gas, chemically inert to the molten tin. Instead of feeding a ribbon of glass, as shown in Fig. 6 the glass may be poured from the spout lip 4, the flow being regulated by a gate 10 and tweel 2, the lip 4 being spaced to give a free fall to the bath 15 and to ensure the formation of a heel 36 behind the lip 4. As shown in Fig. 8, transverse pairs of horizontally disposed edge rolls 38 acting on the upper surface of the body 31 of molten glass may be provided to assist the rolls 27, 28 in alternating the ribbon 35. Specifications 518,415, 769,692 and 893,664 are referred to.

Abstract: 642,942. Spinning yarns. HIENSCH, J. N. Dec. 15, 1948, No. 14371/46. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 13, 1946.] [Classes 120(ii) and 120(iii)] [Also in Group XXXV] In the preparation of fibres for spinning, the draft is varied during drawing of the fibres, to offset inequalities in the sliver supplied to the drawapparatus, by electricallyoperated draft-controlling apparatus which is adapted to increase and decrease the draft in proportion to current supplied thereto, the current being supplied from a suitable source and passed through the sliver, which has previously been rendered current-conducting, while the latter is located within the reach of the drawing- apparatus. The sliver 10 is rendered temporarily conducting by immersion in a tank 12 containing an electrolyte or colloidal solution of graphite or metal, or having other means of applying finely-divided conducting material, the fibres then being dried; or the conducting material may be applied dry. The sliver is then passed between the feed rollers 14 and 15, one or both of these being driven by an electric motor 22. Draft is applied by the drawing- rollers 25, 26, the roller 25, or both rollers, being driven by an electric motor 33, the speed of which is controlled by a resistanceresponsive controller 42. Current is passed through the portion 49 of the sliver 10 between the rollers 25, 26 and contact-rollers 34, 35, fluctuations in the current, caused by variations in the thickness of the portion 49 acting through the controller 42 to increase or decrease the speed of the motor 33 and thus vary the draft to give a sliver of even thickness.

Filed: 1937-05-26
Abstract: 482,328. Valve amplifying circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. May 26, 1937, No. 14650. Convention date, June 4, 1936. [Class 40 (v)] In an amplifier maximum power is obtained from the last valve when negative feedback V<b> is taken from a resistance R in series with the anode load and from a fraction alphav of the anode load by arranging that R/2alpha is equal to the internal resistance of the valve. The resistance of the load is preferably twice as large as the internal resistance of the valve. An amplifier is also described with a push-pull output in which the feedback is taken from a network arranged between the two parts of the output transformer primary winding and from an auxiliary winding on this transformer. If a condenser C is included in the feedback path the phase change introduced may be compensated by arranging it in series with a resistance and adding a coil L in series with the series resistance R such that R = #L/C.

Title: Improved process of treating sensitive photographic film
IPC: G03C1/74
Filed: 1937-06-26
Abstract: 503,092. Stabilizing photographic emulsions. KODAK, Ltd. (Eastman Kodak Co.) June 26, 1937, No. 14745. Drawings to Specification. [Class 98 (ii)] The sensitometric characteristics, e.g. speed contrast and tendency to fog, of photographic material comprising a cellulosic film support having coated thereon a layer or layers of gelatino-silver halide emulsion are stabilized against change under subsequent storage conditions of varying temperature and humidity by placing it in an environment of such dryness that it reduces the moisture content of such material to the same as that obtained when such material is brought into moisture equilibrium with an atmosphere of ordinary room temperature and pressure, and a relative .humidity of less than 2 per cent, preferably less than À5 per cent, and keeping it in such environment for at least two and a half weeks. The material may be kept in an environment containing calcium chloride, magnesium perchlorate, activated carbon, activated alumina, silica gel or sulphuric acid, or in an environment in which the moisture is removed mechanically as by continually circulating the air through a refrigerating unit, or in a vacuum in which the moisture is removed by pumping. The film may be kept in such environment at a temperature of about 70‹ F. The treatment is especially applicable to film comprising a cellulosic support made by dissolving the basic material in organic solvents and allowing the solvents to evaporate and having between the support and the sensitive emulsion a substratum layer comprising a colloid, e.g. gelatine, which is coated on the support in the form of, a solution with water and other solvents, especially those having a softening action on the support, e.g. acetic acid or acetone. Examples of suitable supports are nitrate and acetate esters of cellulose including mixed esters, such as cellulose acetate propionate or acetate butyrate. The treatment can be applied to films in which several weeks occur between the coating of the substratum and the coating'of the sensitive emulsion and can be applied several weeks after the coating of the emulsion. The treatment is especially applicable to cellulosic film supports coated with silver bromide emulsions not containing optical sensitizers, for example sensitizing dyes, and with emulsions of relatively low sensitivity, fine grain and high gamma and may be applied also to film coated with high speed and sensitized emulsions. Graphs are given showing the effect of storage under varying conditions on speed and contrast of untreated film and film treated for periods of approximately two and a half, five, and nine weeks.
