Title: Rolling mill for rolling anular blanks
IPC: B21H1/06
Filed: 1973-02-19
Abstract: 1393209 Rolling annular work OLEODINAMICA DONZELLI DI DONZELLI & BERETTA 19 Feb 1973 [24 May 1972] 8057/73 Heading B3M A ring rolling mill for rolling an annular blank 9 includes an internal mandrel 11 which rotates about a fixed axis, and an external roll 4 which is fed (together with its driving motor 2 on a slide 49) towards the mandrel, the feed rate being adjusted inversely with respect to the loading on the motor. The feed is automatically stopped or reversed when the blank has reached a desired size (sensed by a roller 10) or when overloading takes place. The roller 10 is automatically compensated for variations in the temperatures of blanks. The roll 4 is of composite construction to cater for blanks of different axial length. The mandrel 11 is normally supported in bearings above and below a blank, but is raised vertically when the blank is changed. An hydraulic motor 20 rotates the mandrel, and a mixed system of air and water cooling is provided for it. A blank is supported laterally during rolling by rollers 33, Fig. 3, carried on pivotable arms 32. A workpiece ejector blade 41 is associated with one of the arms. The motor 2 is supported on a bearing 6 to permit its stator to be moved, and has its output controlled by a unit 42. The sensing roller 10 is rotated by an hydraulic motor 17, but is modified in operation by a device 12 sensitive to the temperature of a blank. The rolling operation, together with feeding and delivering of blanks, may be performed automatically by an electro-hydraulic control system.

Abstract: 1,000,173. Gauging diameter of grooved workpieces during rotation. DAIMLER-BENZ A.G. Feb. 28,1963 [March 3,1962], No. 8172/63. Heading G1M. [Also in Division B3] Apparatus for gauging the diameter of a grooved workpiece during machining e.g. grinding, comprises means for sensing the grooves and preventing the gauging elements from entering therein. A rotating shaft 1, Fig. 1, to be gauged, has a groove 2 and contact gauging elements 4, 5, carried by pivoted arms 6, 7 drawn together by a light spring 13. Strips 11,12 secured to the ends of the arms remote from the gauging elements extend into a device 8 for transmitting a signal dependent on the shaft diameter. Electromagnets 14, 14<SP>1</SP> are located adjacent the strips 11, 12 and are connected to a control device 20. Polepieces 23, 23<SP>1</SP> and 24, 24<SP>1</SP> are arranged axially and adjacent the gauging elements 4, 5 respectively. The windings of the polepieces are connected to a further control or timing device 29 which is connected to the control device 20. In addition to serving as a diameter indicator the control device 20 includes relays for controlling the machine tool to which the apparatus is applied e.g. speed of feed of grinding wheel. The polepieces 23, 23<SP>1</SP> and 24, 24<SP>1</SP>, when the groove passes, produce pulses which are transmitted to the control devices 29, 20. The magnets 15,16 are actuated to hold and release the arms 6, 7 of the gauging elements, these operations are however, conditioned by a delay or timing mechanism in the control 29 so that the gauging members are only released for a short time on to the continuous portions of the shaft surface. Alternative arrangements when the inductive polepieces are staggered relative to the gauging elements and when contact shoes engage the work in lieu of inductive members, are described.

Filed: 1917-06-15
Abstract: 116,745. Dicker, S. G. S., (Lambert Process Co.). June 15, 1917. Brick kilns.-In a method of burning bricks, the kiln or clamp of bricks is tired to produce a zone of incandescence in the neighbourhood of the combustion apparatus; the firing is then discontinued and the incandescent zone is caused to traverse, t h e remainder of the clamp, preferably by means of a steam and air blast. The firing is conducted at such a rate that the draught is choked and a blanket of steam is formed in advance of the incandescent zone. The clamp is built under a roof carried by braced supports 16. 17 and having side extensions, the vertical walls of which are formed by removable board panels. A layer of burnt bricks is first laid, and on this are built the arches 26 into which the burners play. Above the arches the dried bricks are piled to the desired height, and the top is covered by a platting layer of burnt bricks. The walls are formed by double coal " bricks 28 made by mixing anthracite screenings with the clay, and burnt bricks 29. The clamp is fired by liquid-fuel burners 44, each having a central oil nozzle controlled by a needle valve, and a surrounding steam passage The connexions between the burner and the temporary steam and oil mains 38, 39 are made by a right-angle pipe bend which allows the burner to be swung out of alinement with the extension 31 of the arch, and a fexible oil tube When the fuel supply is cut off, the burner is used to deliver a, steam and air blast to the kiln, and this is distributed through a pipe-fitting 53, Fig. 7, having a yoke-piece 58 on which the burner rests, nozzles 56, and an upturned end 57. This pipe fitting is inserted into the arch when required. Suspended rods 37 are arranged to indicate the "settle" of the bricks during firing. In operation, the burners are started with a moderate supply of oil which is gradually increased until the flames fill the arches from end to end. Combustion is then forced for six hours, and afterward gradually reduced during a period of eight to twelve hours, when the fuel may be shut off. The pipes 53 are then inserted in the arches, and the steam is turned on, carrying with it an air blast info the kiln, The blast is continued until the zone of incandescence reaches the top of the kiln, or it may be turned off at the end of twenty-four hours, and the burning allowed to finish under natural draught. In the early stages of firing, excess air is admitted for the combustion of the coal in the wall bricks 28, the heat so produced acting locally at the sides oF the clamp.
