[Class 59.] In a mill having concentric inner and outer rows of balls means are provided for delivering material to the inner side of the inner row of balls and for restricting the flow of material from the outer row to the space between the rotary ring and casing. As shown two upper rows of balls 15, 16 and a lower row of balls 21 are driven by an intermediate revolving grinding ring 12. The lower row of balls is provided with a stationary track 22 and the upper rows of balls 15, 16 with non-rotary, vertically movable tracks 17, 18 pressed down by springs 19, 20. The ring 12 is driven by projections 12a and 37a on the ring and a frame 37 respectively, the frame being fixed to a driving shaft 23 and being provided with a skirt carrying sweepers 39 which discharge the ground material to an outlet 40. The shaft 23 is mounted on a thrust bearing 231 and is driven by a train of wheels consisting of bevel wheels 28, 27 and cog-wheels 25, 24. Material is fed to the mill through a pipe 31 and passes through the rows of balls 15, 16 and falls between an adjustable ledge 35 and the rotary ring 12 to the lower row of balls 21. After passing through these balls it falls through passages 36 and is swept out of the mill by the arms 39. The ground material is raised by a bucket elevator to a separator from which the coarse material is returned to the mill.

Title: Vehicle roof hatch
IPC: B62D29/04
Filed: 1977-08-04
Abstract: Such a component, e.g. a component designed as a roof-like cover, has a convex circular upper shell (1) with bent rims and a circular lower shell (2), likewise with bent rims and with a recess (4) for the reception of a closing part. The shells (1, 2) are connected to one another along their rims in a region (3). A radial reinforcement (5) serves to accommodate a holding arm (6). The hollow space formed by the shells (1, 2) is filled completely with polyurethane foam (7). The degree of deformation of the shells (1, 2) can be adjusted by control of the foam pressure and high resistance to denting and weight-bearing capacity of the component can be achieved despite the reduction in the wall thickness of the shells and this at low manufacturing costs. <IMAGE>

An electrode assembly for a lead acid storage battery is formed by simultaneously feeding and spirally winding on a mandrel a positive and negative electrode of lead foil each interposed between paperlike layers of porous insulating material further layers of paper-like porous insulating material being interposed between adjacent layers of paper-like insulating material on opposite surfaces of the lead foil and before the foils and layers are wound on the mandrel a paste of colloidal negative electrode material i.e. Pb and a paste of colloidal positive electrode material i.e. PbO 2  are fed and deposited in contact with the surface of their respective electrode foil. In making the lead-acid storage battery the completed roll 3 of the layers and foils is slipped off the mandrel and a plastic bolt 35 is centrally positioned by means of annular plastic spacers 37 within tube 3. Lead wool 39 is then placed against each end of the roll so that it contacts each turn of foil. Perforated lead plate 41 are slipped over the ends of plastic bolt 35 one of which in electrical contact via the lead wool with the positive electrode has a lug 43 providing a positive terminal while the other lead plate 41 has a lug 45 providing the negative terminal. Perforated plastic plates 47 are clipped over the ends of bolt 35 and lugs 43 and 45, and plastic nuts 49 are applied on the opposite screwthreaded ends of bolt 35.
