Abstract: 842,362. Grinding and polishing. glass. MANUFACTUERS DES GLACES ET PRODUITS CHIMIQUES DE SAINT-GOBAIN, CHAUNY & CIREY. S. A., DES. Sept. 10, 1956 [Sept. 8, 1955], No. 27673/56. Class 60. The reactions of a rubbing tool F, Fig. 1, for grinding or polishing a moving glass ribbon, upon the members transmitting movement thereto are at least partially balanced by the action of a centrifugal force produced by at least one balancing mass m which is arranged to rotate synchronously with the tool but out of phase therewith by n# radians when n is not an integer. The tool F is disposed above a moving glass ribbon and rotated by two motors M through shafts D disposed in a fixed frame B, cranks L, and shafts G which rotate in bearings P, P 1  disposed in the tool. Also mounted in the frame and tool are two similar sets of shafts D 1 , G 1 , and a balancing mass m is rigidly attached to each shaft G 1  with a view to balancing the resultant of the centrifugal force of the tool and the force due to friction between the tool and the moving glass ribbon ; the out of phase rotation of the masses being suitably selected. If desired, the masses m may be attached directly to the shaft G. In the modification shown in Fig. 5, each balancing mass T is driven by an electric motor S fixed to the tool F and electrically synchronised with a pilot motor U coupled to one of the motors M driving the tool ; the out of phase rotation of the mass or masses T is selected by suitably adjusting the angular position of the stator of the pilot motor U by means of a worm W. In a further embodiment, the cranks are replaced by an eccentric comprising members 7 and 8, Fig. 2, the latter carrying an adjustable balancing weight 9, which may be of lead, cast iron or mercury. The eccentric is disposed in roller bearings 5, 6 with its axis A 1 a distance from the axis E 1  of the shaft 2 which is mounted in a bearing 4 in a housing 3 having a splined engagement 14 with the member 7 so that the two parts rotate together but allow the tool to be moved in a vertical direction to compensate for wear of the tool or abrasion of the surface being treated. The members 7, 8 may be angularly adjusted relative to each other about a journal 10 coaxial with the axis At and locked in the adjusted position by a screw 11.

Title: Engine driven soil working machine
IPC: A01B63/10
Filed: 1973-06-14
Abstract: 1435751 Driving soil working machines KOEHRING CO 14 June 1973 [5 July 1972] 28259/73 Heading A1B [Also in Division B7] Soil pulverising apparatus which operates at a constant working depth once having been manually set, comprises a horizontal tool supporting rotor shaft which is driven by two low speed, high torque hydraulic motors 20, Fig. 6, connected to the ends of the rotor and powered by fluid from a hydrostatic pump 71 driven by a tractor engine 4 which also drives the tractor wheels via a hydraulic traction pump 70 and a hydraulic motor 74. The speeds of the motors are manually and independently controlled by control levers 60, 61 with the rotor motor, preferably 'being driven through at least two speed ranges by way of selector valve 86. A hydraulic control 115 enables the traction pump 70 to sense the load imposed upon the hydrostatic pump 71 by the loads imposed on the rotor to automatically regulate the machine speed independently of the manual control 75. Depth control:- The working depth is set and maintained by a mechano-hydraulic system which includes a rotary servo valve 175, Fig. 7, and visual read out 64. The servo valve controls fluid flow to hydraulic rams 50 (see also Fig. 3) which raise or lower the rotor support arms 9, Fig. 3, and move the rotor in guide slots 40. The valve includes two independently rotatable servo shafts 185, 186 and a manual control wheel 65 which rotates and sets the shaft 185 to fix the working depth. Any deviation from this depth is transmitted to the rotor shaft 186 via a cable 195 and chain 191. Rotation of the shaft 186 causes it to be out of phase with shaft 185 whereupon fluid is directed via port 180 or 181 to restore the correct depth.  The working tools rotate in a direction counter to the direction of travel and are shrouded by a hood 15, Fig. 3, which has a hydraulically pivoted gate positioned centrally at the rear and provided with clearance slots for the rotor tools. This provides an even worked surface. The tools may be tines.
