Title: The thermodynamic pin gate nozzle
Inventor: ZIMMERMANN WOLFGANG PROF DIPL
IPC: B29C45/27
Filed: 1988-03-19
Abstract: The thermodynamic pin gate nozzle combines the advantages of the pin gate systems on the market: the heating of the runner during the injection phase and holding pressure phase and the possibility of runner blocking at the end of the holding pressure phase and during the cooling time by switching off the nozzle heating. In addition, two further advantages arise: due to the relatively large runner cross-section or due to the melt deformation taking place only once at the nozzle tip, there are only low shearing stresses or orientations of the macromolecules. Secondly, with the existing holding pressure, the gate is blocked in a gentle way, without impact, by switching off the nozzle heating, and consequently the plastic core of the moulding, already transforming into the elastic state, is not deformed.

Title: Device for the axial retention of the differential-wheel shaft of a differential
Inventor: PFAU WERNER
IPC: F16H48/08
Filed: 1988-05-06
Abstract: A description is given of a device for the axial retention of the differential-wheel shaft (4) of a differential, especially one for motor vehicles. In order to avoid a situation where axial retention is achieved at the cost of weakening the differential case (1) or the differential-wheel shaft (4) in zones subject to heavy loading, the invention provides for axial retention in the interior of the differential case (1). For this purpose, use is made of a distance sleeve (7), which is slipped over the differential-wheel shaft (4) and spans the distance between the differential bevel gears (5, 6). The distance sleeve (7) is fixed axially on the differential-wheel shaft (4). <IMAGE>
