Title: Improvements in and relating to dust collecting apparatus
IPC: E21B21/07
Filed: 1953-01-09
Abstract: 734,613. Fluid-pressure servomotor-control systems. HOLMAN BROS., Ltd., HOLMAN, A. T., ORAM, M., and JAMES, E. B. Jan. 8, 1954 [Jan. 9, 1953], No. 729/53. Class 135. The dust produced by a rock drill or other device is drawn away by suction and deposited in a container, and when a given quantity of dust has accumulated, and/or on failure of the suction, a valve is actuated to stop the operation of the device producing the dust. The compressed air supply actuating the drill &c. flows along a line 23, 24 and acts on the piston face of a stop-valve 25 to open it against the action of its loading spring 28. The compressed air also bleeds through a passage 29 to a control chamber at the back of the valve, and the pressure which tends to build up in the control chamber pushes open a light valve 31 and escapes to atmosphere. The dust is collected in containers which are spring-supported on a pivoted frame. When a sufficient quantity of dust has accumulated, the weight thereof lowers the containers which contact the valve 31 and push it into the closed position. Pressure now builds up in the control chamber and, with the help of spring 28, valve 25 is forced to the closed position to cut off the supply of compressed air. The suction line communicates with the casing of valve 31 at 36 and the suction acts on the inside of a bellows 34, through which the stem of valve 31 passes, and it keeps the valve in its raised position. Should the suction fail, the spring of the bellows will push valve 31 to the closed position and valve 25 will, as before, also close.

A sealing ring 5 to prevent fluid leakage between two elements, such as a piston 7 and a cylinder 8, is made of rubber or like resiliently deformable material and has its cross section defined by symmetrically arranged tangentially merging alternate convexly and concavelycurved portions 15 and 16 respectively, the radius of curvature of all the concave portions being equal and the radius of curvature of all the convex portions being equal but less than that of the concave portions. The radius of curvature of the convex portions is not more than half that of the concave portions which latter figure is not less than a third of the major cross sectional thickness X, X of the ring. None of the curved portions 15, 16 subtends an angle greater than 180 degrees. The ring is housed in a groove 6 in the piston 7 and is an interference fit between the bottom 6a of the groove and the cylinder wall. In operation, the ring is pressed and deformed by the fluid pressure into sealing contacts with one side and the bottom of the groove and the cylinder wall.

Filed: 1926-01-11
Abstract: 246,139. British Thomson-Houston Co., Ltd., (Assignees of Baker, W. R. G.). Jan. 14, 1925, [Convention date]. Drawings to Specification. Wired wireless systems. - Relates to arrangements in which wired wireless signals are superimposed on power currents, as in a railway D.C. distribution system, regions (such as sub-stations) unsuitable for the passage of carrier currents being shunted by conductors to which the carrier currents are confined. According to the invention, the latter result is effected by arranging, in series in the power line, rejector circuits each of which comprises a few turns of wire shunted by a tuning condenser; and the avoided regions are shunted by conductors which are connected directly, as opposed to capacitatively, with the parts of the system which convey the carrier current. Switches in the power system may be shunted by condensers.

[Also in Group XL (c)] A copying machine in which the deflection of the stylus causes a D.C. control voltage, produced in an unstated fashion, to be injected into a control circuit, comprises a transformer T, Fig. 2, which supplies a sinusoidal voltage, Fig. 1a, to valves Via, V1b of an Eccles Jordan type trigger circuit which converts it into a rectangular voltage waveform, Fig. 1b. This rectangular voltage is passed to the grids of valves V2a, V2b of a symmetrical Miller integrator which converts the rectangular wave into a triangular wave, Fig. 1c, 90 degrees out of phase with the original sinusoidal voltage. The rectangular voltage is also applied to a stage including valves V3a, V3b, V4a, V4b having bridge connected anodes and which are switched on and off by the rectangular voltage. The cathode impedances of these valves is varied in accordance with the D.C. control voltage by applying the D.C. voltage to cathode-coupled control valves V5a, V5b constituting a long tail pair, the output voltage at each anode junction of the bridge valves V3, V4 being generally rectangular and having an amplitude proportional to the D.C. voltage and being in phase with the switching voltage for one polarity of the D.C. as indicated by the full lines of Fig. 1d, and in antiphase as indicated by the dotted lines of Fig. 1d. The output from this latter stage and from the integrating circuit, Fig. 1c, are added together, Fig. 1e, for intermediate values of the D.C. control voltage of one polarity, and that of Fig. If for intermediate values of the D.C. control voltage of opposite polarity, the phase displacement # and the shapes of the waveforms 1e, 1#, depending on the magnitude of the D.C. voltage. On applying this resultant voltage to control the triggering of a further trigger circuit V6a, V6b, a rectangular voltage output will be obtained which is displaced with respect to the reference voltage 1a by 90 Œ #, where # depends on the magnitude of the D.C. control voltage.

Title: Roll stand for preliminarily descaling band steel mechanically
Inventor: BALD WILFRIED
IPC: B21B1/22
Filed: 1987-01-07
Abstract: The rolling mill for mechanical descaling of hot rolled steel is constructed according to the slidable roll process with reducing rolls so that a unform operation with different and/or changing shape steel strips can obtained. This is attained when the rolling mill has at least two rolls slidable in opposite directions whose body surfaces are constructed with S-shape contours positioned inversely to each other so that these contours compliment each other flawlessly in one certain axial relative position. When sliding the rolls in opposite directions in one case the contour is decreased in the center region of the steel strip and when slid in the opposite directions in the other case the contour is increased in the center region. Thus the rolls can be adjusted to fit a gently convex steel strip profile by axially sliding the rolls in opposite directions as also rolled strips with a thickness centrally reduced in comparison to that of the edge regions can by appropriate sliding of the rolls opposite each other.
