Filed: 1923-11-15
Abstract: 216,795. Rushen, P. C., (Krupp Akt.-Ges. Grusonwerk, F.). Nov. 15, 1923. Ball mills.-The partition walls of compound tube mills are provided with elongated or grid-like openings into each of which an interchangeable sieve-bar projects so that slots are formed between it and the edges of the opening to allow the material to pass from the preliminary to the fine grinding chamber. As shown, the segments 1, Fig. 1, of the partition wall are arranged around the central piece 2 and have openings 3 into each of which a sieve-bar projects, and the bars 4 of the openings of one segment are combined to form a grid-like frame 5 which, by means of bolts 7, is detachably connected to the segment. The material on passing through the slots 9 between the walls of the openings 3 and the bars 4 falls through the frame 5 and passes through a slit 8 into the finegrinding chamber. To alter the width of the slots 9, the frames 5 are removed and replaced bv others with bars of a different size. By unscrewing the screws 7 connecting the frames 5 with the segment 1 and the rear wall 6, the rear wall segment and the frame can be lifted off. The central piece 2 of the partition wall may also be provided with sieve apertures formed in the same way as in the case of the segments. The sieve-bars 10, Figs. 3 and 4, may be mounted on the frame so as to be removable, the ends 13 of the bars lying loosely in recesses 11 in the frame 12 which is fastened to the partition wall.

Patent GB-710303-A (GB)
Title: Dyeing process
IPC: D06P1/22
Filed: 1951-12-14
Abstract: Textile materials of aromatic polyester synthetic linear condensation products, e.g., polyethylene terephthalate, are dyed with vat dyestuffs by treating them in a bath containing an acid leuco derivative of the vat dyestuff and a swelling agent for the polyester and subsequently oxidizing the leuco compound in situ on the textile. Specified swelling agents are phenols, e.g. o- or p-phenyl-phenol, and diphenyl.  Vat dyestuffs of the anthraquinone (including polynuclear quinones other than anthraquinone), indigoid or thioindigoid series, e.g. 1\sv: 2\sv : 6\sv : 7\sv-dibenzpyrene-7 : 14-quinone and Caledon Jade Green XNS, may be employed.  The dyeing is preferably effected at or near the boiling point of the dyebath or above the boiling point at superatmospheric pressure.  The dyebath may be prepared by treating the vat dyestuff with a reducing agent, e.g. zinc formaldehyde sulphoxylate or sodium hydrosulphite, and then acidifying the alkaline solution with, for example, acetic acid, to form a suspension of the acid leuco compound, the swelling agent being added before or after the precipitation of the leuco compound. Specified oxidizing agents are nitrous acid and hydrogen peroxide. In examples, the dyebath also contains disodium dinaphthylmethanedisulphonate.

Title: Improvements in or relating to systems for controlling the rate of fuel feed to gas turbine engines
Inventor: BELL FRANCIS ROBERT
Filed: 1955-10-14
Abstract: 797,695. Gas turbine plant; centrifugal and axial-flow compressors. BLACKBURN & GENERAL AIRCRAFT, Ltd. Oct. 14, 1955, No. 29369/55. Classes 110 (1) and 110 (3). Surge in a gas turbine engine is prevented by sensing the minor fluctuations in the compressor air pressure which precede surge and using them to diminish the fluel supply to the engine. The air pressure in the combustion chamber of the gas turbine plant is communicated through a line 1 and applied to a chamber 2 on one side of a flexible diaphragm 3 and, through a throttling restriction 4, to a chamber 5 on the opposite side of the diaphragm. During acceleration, the pressure in chamber 2 closely follows the rising discharge pressure of the compressor, while the pressure in chamber 5 lags behind, so that the diaphragm 3 initially acts on a lever 6 to tend to hold a fuel spill valve 7 closed. Subsequently, on the occurrence of the small initial pressure fluctuations preceding the onset of surge in the compressor, the pressure in chamber 5, which cannot respond to the fluctuations, becomes intermittently greater than the pressure in chamber 2, which responds to the fluctuations, so that the diaphragm 3 rocks the lever 6 to unseat the valve 7 to spill some of the fuel. The reduction in fuel supply prevents the onset of violent surge. Movement of lever 6 is limited by set-screws 12, 13. The apparatus may be used in combination with a temperature controller of the quartz rod or mercury vapour type providing a direct limit on the accelerating temperature or with a known type of air/fuel ratio temperature control equipment. Specification 734,018 is referred to.

Title: Improvements in mechanical relays for measuring instruments such as bimetallic thermometers
IPC: G01K5/70
Filed: 1936-10-29
Abstract: 469,531. Thermometers. BLOCH, G. Oct. 29, 1936, Nos. 29429 and 29430. Convention dates, Oct. 29, 1935 and March 27, 1936. [Class 97 (iii)] [Also in Group XXXVIII] An indicating member is driven by a mechanical power-storing device until the latter is arrested by a stop the position of which is determined by a sensitive measuring element such as a bimetallic temperature sensitive element. The arrangement is particularly in tended for use as a clinical thermometer. As shown, the bimetallic helix 1, which may be immersed in liquid and provided with a damping vane 5, is enclosed in a metal sheath 3 and moves a spindle 4 carrying a coarse reading pointer 7 and a disc 6 with a stop 8. By operating a push button 10 a brake lever 9 is applied to the disc 6 and held by the catch 11 and a catch 14 is simultaneously moved to release a gear 16 connected to the winding spring 17. The gear 16 drives a gear wheel 18, carrying a fine-reading pointer 21. A gear wheel 19 fixed to the gear 16 drives a gear 20 carrying a stop 22 adapted to arrest the drive when it contacts with the stop 8. Operation of a push-button 12 releases the catch 11 allowing the brake lever to be withdrawn by the spring 13 and resets the gear 16 by means of the levers 23, 24. The housing 25 may be closed at the top by a magnifying glass 27. In the modification shown in Fig. 7, the bimetallic helix 1 drives a disc 3 with a stop 4 and operation of the push button 5 first causes a friction disc 7 to clamp the disc 3, and then rocks the lever 11 until a retaining pin 12 thereon releases the toothed sector 13. The latter then rotates under the action of a spring 14 until a pin 17 contacts with the stop 4. The sector 13 drives a pinion 15 carrying the pointer 16. When the push button 5 is released it is raised by a spring, an abutment 18 on the disc 7 engaging a projection 19 on the sector 13, restoring the latter and the pointer 16 to the original position. The button 5 may be retained in the depressed position by locking means (not shown).
