Patent DE-2428626-A1 (DE)
Title: Vertical hammer mill for very fine powders - has stacked horizontal wheels on common vertical shaft in chambers
Inventor: ROHRBACH HANS DR ING
IPC: B02C13/14
Filed: 1974-06-14
Abstract: The hammer mill has a vertical main shaft so that individual hammer wheels rotate in horizontal plates. The material to be ground falls downwards through wheels under gravity and the outlets and inlets of each stage are staggered by half a full turn. The size of the hammer wheel changes so that the last stage has much higher peripheral speed than the initial stage hammer wheel. This arrangement grinds material down to four micron particle size. The common shaft rotates at ten thousand revolutions per minute. Insert shielding gas such as nitrogen is supplied to the last grinding stage and a cooling jacking is provided.
Patent DE-2432139-A1 (DE)
Title: Bearing arrangement for machine with unstepped shaft - has drive end ball bearing with sliding fit on shaft
Inventor: WEISS ARNOLD
IPC: F16C35/08
Filed: 1974-07-04
Abstract: The application is to small electric motors where a plain shaft without steps is used, and a plain bearing (3) is employed at the non-drive end. The ball bearing at the drive end is a press fit in the fixed bearing housing (8). The inner race (9) is a sliding fit on the shaft (2). An axial bearing at the non-drive end takes up the end thrust produced by the spring (10) which acts via a collar on the inner race (9) of the ball bearing (4). Typically the spring is of wavy form and presses against the rotor iron. The elastic pre-loading thus produced between the inner and outer races aids quiet running and reduces wear.

Title: Belt conveyor for loading bulk cargo into ships - has cantilever arms adjustable by jacks in three directions to meet varying tidal conditions
Inventor: KAMM WILLIBALD FRITZ GUSTAV DI
IPC: B65G67/60
Filed: 1975-12-19
Abstract: A dock installation is used to transfer bulk cargo from a silo into the cargo hold of a ship. A number of adjustable belt conveyors are used. Each cargo hold is thus supplied by its own conveyor, which in turn is fed from its individual silo. In order to cater with varying tidal conditions and with different shapes of ships, the belt conveyors are adjustable in three directions.

Title: Compensator from rubber for tube joining - using an ethylene propylene terpolymer, a natural and a bromobutyl rubber
Inventor: ALPERS ERIKA DR
IPC: F16L51/02
Filed: 1976-02-17
Abstract: Compensator for joining tubing, using strengthened rubber, consisting of a convex widening tube with end fastening flanges, the flanges joining steel crd layers, arranged crosswise, coated and embedded in rubber. The tube consists of ethylene propylene terpolymer rubber (EPDM). The double adhesive layer on the Zn coated steel cord comprises an inner layer of natural rubber (NK) and bromobutyl rubber, and an outer layer of NK-bromo butyl rubber and EPDM or bromobutyl rubber (BBK) and EPDM. The compensators are used to prevent sound transmission in tubing, to facilitate length equalisation arising from temp. effects and to equalise axial displacements in tubing. The use of EPDM leads to exceedingly advantageous effects relative to the resistance against hot water of various kinds. Dynamic loads at different temperatures are well tolerated. A compensator with flanges for joining tubing consists of a widening ethylene propylene terpolymer (EPDM) outer cover, and embedded Zn coated steel cord layers arranged crosswise, and coated first with a natural rubber (NK) and bromobutyl rubber (BBK) compsn., and then with an outer layer of NK-BBK and EPDM OR BBK and EPDM. It is used for e.g. tube length equalisation.
