Abstract: 1,272,559. Steam turbines. SIEMENS A. G. March 26, 1970 [March 26, 1968], No. 15025/70. Heading F1T. In a steam turbine having an undivided tubular steam chest 27 containing a cross-member 5 supporting admission valve tappets v 1  to v 5  so as to control the opening and closing of the valves 4 associated therewith, the steam chest is arranged such that during assembly the cross-member can be inserted in the generally longitudinal direction of the chest. The latter has bosses 28, 29 to which are bolted covers 32, 33 forming guides for control spindles 9, 10. The chest 27 has openings 25, 26 at its opposite ends and during assembly the cross-member 5 can be inserted through one or other or these openings, the control spindles 9, 10 then being attached to the ends of the member 5 by bayonet type connections 9d, 10d. Fixed or adjustable abutments 9e, 10e are provided on the spindles 9, 10. After insertion of member 5 opening 25 is either blanked-off by a sealing plate or receives a rapid-action stop valve (44), Fig. 7 (not shown), for the control of live steam entering in the direction of arrow 31. Opening 26 is blanked-off by a supporting bracket 30 for the control mechanism of cross-member 5, the control mechanism comprising a hydraulic motor 16 connected to rocker arms 11, 12 which are respectively connected to spindles 9, 10. A compression spring 17 loads rocker 11 in the closing direction of valves 4. The opening and closing sequence of the latter is predetermined by the individual heights of tappet guide bushes 7 mounted in recesses 6 in cross-member 5, fine adjustment being possible by means of nuts 8 on the tappet ends. In a modification, Figs.3 to 5 (not shown), the control mechanism for the crossmember 5 of the initial stages of an extraction steam turbine comprises rocker arms (11<SP>1</SP>, 12<SP>1</SP>) operating in spaced planes (54, 55) parallel to the turbine axis. In this case live steam is admitted to the chest (27<SP>1</SP>) past stop valves (44<SP>1</SP>) disposed at both ends of the chest. Steam flow to the remaining stages is controlled by an arrangement similar to that in Fig. 1

Abstract: 415,228. Stays. HELLIWELL, F., George Street, Mytholmroyd, Yorkshire. May 30, 1933, No. 15553. [Class 65 (i).] A stay for automatically securing a door or the like in an open position comprises a cranked spring arm secured to the door and operating in a slot in a bracket on the door frame, the arm being shaped so that in the required position of the door the cranked portions engage the bracket on both sides. In the form shown, an arcuate spring bar C, having one end bent down at D for fixing to the door, passes through an aperture in a bracket K fixed to the door frame. The free end of the bar is cranked at G, H and formed with a hand-piece J. On opening the door the bar bears against the upper edge of the aperture in the bracket K until in the position shown the springiness of the bar lifts the part G behind the bracket to prevent closing, while further opening is prevented by the part below H engaging the lower part of the bracket. In a modification, the bar is upwardly, instead of downwardly, cranked at H ; in this form the bends G, H form a notch between them, and one or more similar notches may be formed in other parts of the bar to hold the door at different degrees of opening ; the length of the notch between the bends G, H may be little more than the thickness of the bracket K or may be sufficient to embrace the frame member to which the bracket is fixed. The bar may be straight instead of arcuate, in which case it is pivoted to the door. The bent part J may be replaced by a terminal knob or a pendant chain by which the stay is released. The vertical parts of the bar below the bends G, H may be provided with rubber buffers to engage the bracket K.

Abstract: 132,884. Lake, W. H. Sept. 26, 1918. Rolling.-A manipulator, of the type described in Specification 8840/03, for holding and moving rails and the like, is constructed so that the gripping-members j can easily be removed and changed. The annular gapped plates a, b are supported on a frame f by guide-rollers c, d, and carry on their inner faces pairs of opposite pins g, g<1> and h, h<1> respectively. These pins engage in slots m in the gripping-members j, so that when the plates a, b are rotated relatively to one another, the gripping-members are moved together or apart, but when the plates a, b are rotated together, the work is merely turned. The plates a, b, j can be removed and replaced after taking out two or more of the rollers c, d. In a modification, the rotatable plates a, b, instead of being guided by rollers, are mounted on a central spindle, and the grippers j project laterally as jaws. The machine can then be taken down by removing the spindle. In either case, the plates a, b may alternatively be so arranged that, when the grippers j are to be removed, one of the plates can be moved axially away from the other to enable the pins g to clear the grippers j. Further, the pins g, g<1> and h, h<1> may be arranged on one side of the plates a, b, instead of interiorly, one of the plates being slotted to clear the pins on the other: or the plates may be converted into co-axial sleeves for this purpose, with an overhang to cover the grippers j and support the outer ends of the pins. The grippers j may be shaped to take a rail of any section, or may carry rollers over which the work A can be passed, or projections which prevent their gripping the work tightly. In the case where the work is gripped. the machine can be traversed towards the rolling- mills as a whole. The plates a, b are rotated by toothed racks, spur-wheels, worm gear, chains. or ropes.

Methanol, acetone, dioxane, or glycol monomethyl ether, or a mixture of these liquids may be mixed with water and used as the solvent for the partially hydrolysed cellulose ester which is to be treated.  Caustic alkalies, or organic bases such as pyridine or ethanolamine may be used as hydrolysing agent. Cellulose acetate, propionate, butyrate, benzoate, acetate-laurate, or acetate-benzoate, or a cellulose ether-ester may be treated.  The products may be dissolved in organic solvents containing at least 50 per cent of water.  They may be used for coating gelatine layers to be used as eye-pieces for gas masks or for making bodies capable of swelling for medicinal purposes. They may be used for making photographic films.
