Patent GB-481072-A (GB)
Title: Improvements in centrifugal separators with intermittent sludge discharge
IPC: B04B1/18
Filed: 1937-06-11
Abstract: 481,072. Centrifugal separators. AKTIEBOLAGET SEPARATOR. June 11, 1937, No. 16230. Convention date, June 26, 1936. [Class 23] The intermittent sludge discharge from a centrifugal separator is controlled by a slide operated by a liquid which is kept completely separated from the liquid under treatment in the separator. In the separator shown in the the liquid to be treated is supplied through the tube 1, the chamber 2 and the passages 4, 5 to the sludge space 7 bounded by the fixed hood 8 and the movable part 9 which can slide on the nave 3. A lower member 21 is fixed to the slide 9 and a member 13 fixed to the nave projects into the space between the upper and lower members of the slide to form two chambers 14, 22. Operating liquid is supplied through the channels 15, 16 to the chamber 14 at a greater rate than it leaks away through the passages 17. The chamber 14 therefore normally contains liquid to the level of the overflow passage 20, and thus holds the slide 9 firmly against the packing 18 to close the sludge discharge aperture 19. When the sludge deposit is sufficient for discharge, the supply of liquid to the separator is cut off and the pipe 15 is closed. The liquid in the chamber 14 passes through the passages 17 and operating liquid is supplied to the chamber 22 through the pipe 23. This forces the slide 9 down to open the aperture 19 to permit the discharge of the sludge. The bowl may be provided with a sludge indicator. In a modification the passages 17 are dispensed with and the excess of operating liquid supplied to the chamber 14 flows out through the channel 20 which is just large enough to take the normal flow. When this is increased, the liquid flows through another channel to the chamber 22 and thus operates the slide. In another modification the pressure chambers 14, 22 are located in a chamber below the bowl. In a further modification a spring is used to move the slide 9 downwards to open the sludge discharge aperture after the supply of liquid to the chamber 14 has been stopped.

Title: Improvements in or relating to Steam Turbines.
Inventor: BAUMANN KARL
IPC: F01D25/30
Filed: 1916-11-14
Abstract: 111,153. Baumann, K. Nov. 14, 1916. Axial-flow type; casings; exhaust, disposing of.-Relates to axial-flow turbines having exhaust casings fitted with guides for outwardly deflecting the steam leaving the moving blades, and with internal guide-walls located in planes substantially parallel with the turbine shaft which divide the exhaust steam into segmental portions, and consists mainly in extending these internal guide-walls right across the exhaust blade area, and in shaping them so as to obtain compact and easy exhaust paths for the steam. The internal guide-walls 3, 4, which may be mounted in a removable frame 15, Fig. 6, extend across from the outer to the inner circumference of the exhaust area of the moving blades 2, and their upper portions are formed to substantially involute curves, the base circle from which such curves are described being preferably of less diameter than the diameter of the outer circumference of the exhaust blades 2 and occasionally less than that of the inner circumference thereof. The guide-walls may be extended by webs 5, 6, which strengthen the exhaust casing so that, if desired, the turbine may be supported from feet located at the ends of its exhaust casing only. as described in Specification 110,791. Additional division waits 8. 9 of helicoidal shape and a V- shaped portion 7 may be provided in the upper half of the exhaust casing, and walls 10, 11, 12, 13 in the lower half. with or without a transverse web 14. In a modification, the invention is shown applied to a multiple-exhaust turbine of the kind described in Specification 14053/15 having an exhaust casing similar to that described in Specification 105,933. A further modification relates to an exhaust casing located centrally between ahead and astern turbines. The number of guide-walls employed may vary from two upwards according to the size of the turbine. With exhaust casings. which are not symmetrical about the vertical axial plane, as shown for example in Figs. 25, 26, and 27 of Specification 105,933, the whole of the exhaust blade area may be divided up by the guidewalls into sections alike in shape. Other curves than involutes are indicated for the guide-walls. A portion only of the exhaust steam may be handled by the described casing, the other portion being led away by an exhaust casing of any suitable known type.
Patent GB-809188-A (GB)
Title: Improvements in or relating to centerless grinding machines
IPC: B24B47/04
Filed: 1957-05-22
Abstract: 809,188. Shaft couplings; change-speed control. LIDKOPINGS MEKANISKA VERKSTADS A.B. May 22, 1957 [May 23, 1956], No. 16306/57. Class 80 (2). [Also in Groups XXIII and XXXVII] In a centreless grinding machine, the workpiece 3 is supported, in contact with the regulating wheel 2, by a work rest 4; the grinding wheel 1 is movable towards and away from the regulating wheel, its carriage being moved by a gear on a shaft 20 carrying an arm 19 actuated by the track of a cam 16 driven by a two-speed motor 18. A worm 8 driven by an electric motor meshes with a worm wheel 7 secured to a sleeve 9 freely rotatable on the spindle 5 carrying the regulating wheel. One end of the sleeve 9 is formed as a coupling member 10 having axially extending teeth and carries, by rivets 100, a metal ring 11 insulated from the sleeve by members 110 and having radially inwardly extending teeth; secured to the spindle 5 is a coupling member 12 with radially outwardly extending teeth located between the teeth of members 10, 11. As long as the grinding wheel is not in contact with the workpiece, the latter is driven by the regulating wheel, i.e. part 11 drives part 12; the surfaces 28 on these parts being in contact, a circuit is established, on closure of push-button switch 30, to energize a relay 24 which causes the motor 18 to run at fast speed for rapid approach of the grinding wheel. When the grinding wheel contacts the workpiece, the latter tends to drive the regulating wheel, i.e. the part 12 drives part 10. The relay 24 is thus de-energized and, a switch 22 being closed, a relay 25 is energized causing the motor 18 to run at slow speed for grinding feed. This continues until the grinding is completed and the grinding wheel carriage is returned by the cam to its original position, whereupon a projection 21 on the cam opens the switch 22 and the motor 18 stops. The circuit may be modified so that the return of the grinding wheel carriage is also fast. The push-button switch 30 may be operated manually; when workpieces are automatically fed in sequence to the machine from a magazine a member connected to the magazine closes the switch when the workpiece is in its grinding position. When the relay 25 is energized to give slow grinding feed, a low-torque motor 14, 15 is supplied, the rotor 14 of which is mounted on the spindle 5; as described in Specification 796,280, this provides a torque additional to that exerted upon the regulating wheel by the workpiece and maintains the coupling parts 12, 10 in contact despite unevenness of the workpiece surface. In a modification, the worm 8 is axially displaceable and control is effected by movement of the worm when the torque changes. The two speed mats 18 may be replaced by two motors having the same or different speeds connected to the cam mechanism with different gear ratios; a gearbox with electromagnetically actuated couplings may be used to provide the different speeds.

[Also in Divisions C2, C3 and C4] Porous and non-porous materials, e.g. woven fabric, knit fabric, paper, fibre board or felt made of natural or synthetic fibre, glass or wood, are rendered oil repellent by coating them with a homopolymer or copolymer which contains hydroxyalkyl ester units of the formula: wherein R f  is a C 3-21  perfluoroalkyl group, R is a hydrogen atom or a methyl group, p is zero or an integer from 1 to 10, and m is an integer from 1 to 10. The polymer may be applied in the form of an aqueous emulsion, an organic-solvent solution or an aerosol and the composition may also contain stabilizers, pH adjusters and/or other water- or oil-repellent compounds. The coated materials may be dried at room temperature or at elevated temperature and, if desired, subjected to a curing process, during or after which a soaping process may be applied. The properties of the coating may be modified, e.g. to impart water repellency, by treatment with a monofunctional or polyfunctional compound reactive with hydroxy groups. The modifying process may be applied before or after the oil repellent treatment by double-bath treatment although it is also applicable during the course of the oil-repellent treatment by single-bath treatment.
