IPC: F23M5/08
Filed: 1924-03-25
Abstract: 235,952. English Electric Co., Ltd., and Silk, P. B. March 25, 1924. Pulverulent, liquid, and gaseous fuel furnaces.-In a boiler or other furnace fired by pulverized coal (or by oil or gas), damage to the walls and slagging of ash is prevented bv the introduction of cool flue gases through apertures 9 spaced over an inner wall of the combustion chamber, Fig. 2, or at a low level in the combustion chamber. The total quantity of flue gas returned is controlled, jointly or separately, by the bye-pass and main dampers 11, 12 of the fan 6, and in the first form the individual apertures 9 are also controlled by dampers 10. The furnace illustrated is fired by downwardly directed coal-dust burners 2. The dampers 10 may be operated by a toothed curved rack as shown in Fig. 4, or by a screwed spindle and hand-wheel, and they may be conical instead of as shown. In the second form of furnace the hollow wall is used for the supply of heated secondary air.

Title: Color-television image-reproducing apparatus of the image-projection type
IPC: H04N9/18
Filed: 1956-03-12
Abstract: 784,570. Cathode-ray tube circuits. HAZELTINE CORPORATION. March 12, 1956 [April 4, 1955], No. 7648/56. Class 40 (7). In a colour television receiver in which component colour images produced by individual picture tubes are combined in register to form a composite colour image on a viewing screen the beam focus unit of each tube is initially adjusted so that the position of the beam on the tube screen is independent of variations in E.H.T. voltage and focus field intensity and each tube is provided with an adjustable mounting device by means of which optical focusing and aligning of the component images on the viewing screen may be effected. Fig. 2 shows part of one picture tube 60 (three such tubes 60, 61, 62 being employed in a known optical projection system as shown in Fig. 1) provided with beam deflection and focusing devices 54, 55, respectively, both rigidly secured to the tube and the latter provided with an adjustable magnetic shunt element 57b by means of which (by trial and error positional variations) the position of the undeflected beam spot on the screen is made independent of variations in focus current and E.H.T. supply voltage. With this adjustment made the tubes are mounted in the housings 27, 28, 29 (Fig. 1) by means of individual mounting devices which allow the position of each tube to be adjusted relative to its associated optical elements (e.g. spherical mirror 30, plane mirror 32 and aspherical lens 24). Figs. 3a and 3b show one such mounting device which comprises a semi-annular flanged member 75 to which the mounting plate 56 (Fig. 2) of the tube is secured (by means of screws 79c, 79d, 79e) the member 75 being adjustable with respect to a ring member 72 by means of screws 76, 77, 78, adjustment of any one of which rocks member 75 about the line joining the pivot points of the other two against the tension of springs 96, 97, 98, 99 and the ring member 72 being adjustable with respect to the frame section 71 (forming part of the housing 29, Fig. 1) by means of screws 74, 74a and co-operating spring mounts 80 and 80a, respectively, screws 73a ... 73d, passing through oversize holes in member 72, being loosened for this purpose. In this manner each tube may be adjusted to produce a correctly focused and registered image on the viewing screen 36, the previously described adjustments of the magnetic shunts ensuring that such registration does not vary with variations in focusing current and E.H.T. voltage. Specification 773,706 is referred to.

Title: Improvements in and relating to torque transmitting arrangements
IPC: F16D33/16
Filed: 1954-03-17
Abstract: 749,294. Charging pumps. DRESSER OPERATIONS. Inc. March 17. 1954 [March 20, 1953], No. 7818/54. Class 7(2) [Also in Group XXIX] An overrunning clutch for a turbo-supercharger of an internal-combustion engine comprises a hydraulic coupling 10 having a shaft 20 driven from the crankshaft 106 of the engine, and a shaft 22 connected to a shaft 114 between a turbine 116 fed by the exhaust of the engine and a compressor 118. The coupling is of the hydrokinetic type and is continually drained of oil. When the shaft 114 rotates the shaft 22 faster than shaft 20 is rotated, the supply of oil to the coupling is automatically cut off by hydraulically-actuated control means (see Group XXIX), and the coupling consequently empties. The shaft 114 is therefore free to rotate at the speed determined by the turbine. U.S.A. Specifications 2,521,117 and 1,938,357 are referred to.

A glass containing at least 2% by weight expressed as soda mole equivalent of an alkali metal oxide is treated by (1) applying to the article's surface a solution or suspension, in water and/or an organic solvent, of at least one salt of a different alkali metal to form a substantially continuous layer of material consisting of or containing the salt, (2) maintaining at a temperature above the boiling point of the water and/or organic solvent, e.g. 200-760‹ C., the salt-containing material being solid at said temperature, so that ion exchange between the alkali metal in the glass and that of the solid salt occurs to give a stress in the surface of the glass, but for insufficient time to allow stress relaxation to occur, and (3) cooling to a temperature at which ion exchange does not occur, the layer of material and salt being subsequently removable from the glass. The alkali-metal ions in the glass may be exchanged for larger or smaller ions. The salt applied may be a carbonate; K2HPO4 may also be used. The salt layer may be removed by washing with dilute nitric acid. Many examples of glasses which may be treated are given, including some examples of crystallizable glass. The layer may include salts to colour the glass, for example, chlorides, carbonates and sulphates of Co, Fe, Ni, which will diffuse into the glass surface.

A gear manufacturing machine comprises a worktable 2, Fig. 1, rotatable by an hydraulic motor 5, through a worm and wheel 16, 17, a grinding-wheel 3, rotatable by an electric motor 4, and a comparator 11, for comparing signals generated by the motors and controlling the speed of motor 5. The rotation of a radial optical grating 7 fixed to the shaft of motor 4 is detected by a photo-electric sensing head 8 and a further grating 9 on table 2 is detected by a similar head 10. Pulses from heads 8 and 10 are fed to comparator 11, the former pulses passing via an electronic gear-box 12, which corrects the pulses so that these are nominally the same as pulses from head 10. If the signals are out of step, an error signal passes through an amplifier 14 to a servo valve 14a to control the speed of motor 5, the frequency of the error being recorded at 15. A face cam 18 on table 2 co-operates with a follower 24 connected to worm 16, to rotate the latter, and correct for errors in the worm, and wheel drive. Grinding wheel 3, Figs. 2, 3, is adjustably mounted in a vertically movable slideway 26 carried on a horizontally movable slide 26a. Vertical movement of the wheel past work 1 is produced by a wedge 32 driven at an even speed by means 33, which co-operates with a block 29. To produce helical gears, wedge 32, Fig. 4, carries a bar 41 connected to a slide 37, the latter being connected to sensing head 10 by a steel tape 35. Bar 41 is set relative to wedge 32 according to the helix to be produced, and as the wedge moves, head 10 is rotated. To produce gears having either hand helices two such slides 37 connected to a continuous tape are provided.

Title: Improvements in or relating to the production of membrane filters
Inventor: SCHMID GERHARD
IPC: B29C39/00
Filed: 1960-03-12
Abstract: A process for the production of membrane filters of graduated pore size from synthetic resins comprises dissolving the resin in a first solvent, adding to the solution a second and less volatile solvent which is compatible with the solution but does not dissolve the resin, forming a layer from the homogeneous solution so obtained and allowing it to mature without evaporation of solvent, then gelatinising the layer by slowly evaporating the solvents to yield a gel in which the major constituent of the liquid phase is said second solvent, washing out the solvent from the gel by contracting with a liquid which is miscible with the second solvent and drying the resulting membrane filter.  The resin may be polystyrene, the first solvent benzene and the second solvent acetone, methyl acetate, cyclohexanol or methylcyclohexanol.  Large pore sizes may be obtained where the second solvent is a non-solvent for the resin, smaller sizes where it is a swelling agent for the resin.  The membranes may be irradiated, e.g. with a cobalt-60 source, to crosslink the resin, and may be after-treated to introduce ionic groups, e.g. sulphonic acid and quaternary ammonium groups.
