Patent DE-19630537-A1 (DE)
Inventor: NOTHDURFT HEINZ
IPC: F02M39/00
Filed: 1996-07-29
Abstract: A fuel injection pump for internal combustion engines has an integrated feed pump with an outer ring (5) and an inner ring (10) coupled by teeth (12) to a driving shaft (15) of the fuel injection pump. The individual teeth extend with their face (27) and bottom (28) along arcs of a circle around a centre which lies in the driving shaft radial plane which extends through said teeth along the axis of the driving shaft. This allows a higher angular offset between the driving shaft and the plane of the inner ring (10) without increasing the risk of damage through wear.

Patent DE-19724160-A1 (DE)
Title: Hand operated corkscrew
Inventor: MAIER GEORG
IPC: B67B7/04
Filed: 1997-06-07
Abstract: The corkscrew has a housing (1) with a screw (5) mounted on a bearing pin (6) with a rotary handle (7) at one end remote from the screw. The housing also holds a setting plate (8) which has a bore for the bearing pin. The plate is adjustable in an axial direction of the pin by eccentrically engaging a tilt lever (9) which is attached to the housing and has a handle (10). The setting plate is supported on a bearing face (11) and is held against it by a coil spring (12) while being aligned perpendicularly to the longitudinal axis. The bore has a slightly larger diameter for forming a narrow ring gap between this and the pin. This is so that when the plate tilts, friction occurs between the edge of the bore and the pin, preventing the setting plate from moving relative to the pin.

The folder mechanisms may include sets of inter-connected crimping fingers 660, 670, 680 on each side of the wrapping station 150 which are brought together due to a camming mechanism (610 fig 23) to crimp the wrapping paper forming a column-like structure (760 fig 20). A stuffer spindle (732, figs 18-20) can then push the column-like structure (760, fig 20) against the side of the roll and tuck an end portion (762 fig 20) into the central core of the roll (fig 21). Cam mechanisms may also be used to operate the stuffer rods, clamping mechanisms and/or underfolding mechanisms. An aesthetically pleasing wrapping of the roll is thus produced.
