Title: Fine grinding process for generating rounded end on slender shaft - uses grinding tool in form of thick rotating rod with cup shaped end fed angularly against rotating shaft end
Inventor: BECKER MANFRED
IPC: B24D7/18
Filed: 1992-07-22
Abstract: The process generates an end face having the form of a spherical segment on the slender shaft workpiece (1). The rod like grinding tool (3) is thicker than the workpiece shaft. The end of the grinding tool has a dressed central working area (4) conforming to the spherical segment required on the workpiece shaft end. The axis (7) of the rotary workpiece and axis (8) of the rotating grinding tool intersect at an angle less than 180 deg. The grinding tool is changed or re-dressed before the grinding tool surface (11) ceases to overlap the work, or the work surface (2) ceases to overlap the grinding tool surface. A small central blind hole (12) dressed in the centre of the working area indicates when the base of the hole is reached so the tool is changed.

Patent DE-4236896-A1 (DE)
Inventor: MAURY HANS-DIETMAR DR RER NAT
IPC: A01F25/14
Filed: 1992-10-31
Abstract: An air cannon is used for removing adhering and accumulating bulk material in silos, heat exchangers, lines and the like with the aid of blasts of air. The necessary compressed air is stored in a pressure container and passes, via the outlet valve 3 and a discharge nozzle 11 adjoining the latter, into the region of the adhering bulk material and detaches the latter. The outlet valve 3 has a valve housing 9 and a piston 19 which is guided longitudinally in a guide 18 and is acted upon, at the rear, by a closing pressure which can be lowered abruptly. The piston 19 has, at its front side facing the discharge nozzle 11, an annular valve sealing surface 25, inside which, when the valve is closed, the pressure in the discharge nozzle 11 acts and outside which the pressure prevailing in the pressure container acts. In order, in the case of a simple construction of the air cannon, to produce a blast of air having a high momentum, an annular channel 17 which is connected to the pressure container is constructed between the valve housing 9 and the guide 18 for the piston 19. When the valve is open, the annular channel 17 opens, in the form of an entirely cylindrical opening 39, into the discharge nozzle 11. <IMAGE>

Patent DE-4319223-A1 (DE)
Inventor: RECK ANTON
IPC: A01K5/00
Filed: 1993-06-09
Abstract: A fodder distributor with a mounting frame attachable to the three-point suspension of a tractor and with a horizontal distributor roller (9) centrally mounted on the mounting frame is described. So that silage blocks can also be comminuted and distributed in addition to green fodder, it is proposed that a clearing and/or carrying arrangement engaging under the distributor roller (9) be guided so as to be freely vertically movable on the mounting frame, specifically particularly by means of double levers (34). If the fodder distributor has only a clearing plate, it is expedient to support the mounting frame relative to the fodder table via a roller. If a carrying fork (35) is provided as a vertically movable arrangement, this can be made to run on the fodder table on rollers (39). The distributor roller (9) is preferably pivotable upwards by means of a pivoting frame (31), which is driven by a hydraulic cylinder (30). The pivoting movement can also be utilised to lift the carrying fork (35) by means of a pull cord (43). <IMAGE>

IPC: F04F1/08
Filed: 1993-08-19
Abstract: A pump, in particular a deep-well pump, for delivering a liquid, with an outer pump pipe or a pump tube (5) closed off at both ends. The inner space of the pump pipe or pump tube (5) can be put under pressure by a pressure medium. A pressure-medium inlet (1) and an outlet opening (2) for the liquid to be delivered are provided at one of its ends, and an inlet opening (9) for the liquid to be delivered, which can be closed by a non-return valve, is provided at its other end, the direction of passage of the non-return valve being towards the inner space of the outer pump pipe or tube. The pump also has a rising pipe (6) arranged in the inner space of the outer pump pipe or tube. One end of the rising pipe (6) is connected to the outlet opening for the liquid to be delivered. Its other end is open and extends in particular down to just in front of the inlet opening for the liquid to be delivered. In a preferred embodiment for permanently equipping a deep well or level with the deep-well pump according to the invention, the outer pump pipe is formed by a gauge pipe, i.e. the pipe of the level is at the same time the pump pipe. This ensures that the level can be virtually completely emptied in one pump cycle and a further simplification of the structure can be achieved. <IMAGE>
