Patent DE-4109985-A1 (DE)
Inventor: EMRATH NORBERT
IPC: C03B9/38
Filed: 1991-03-27
Abstract: The cooling unit disclosed has a connecting casing which is connected on the input side to a cooling-air supply line and on the output side, when the mould is closed, to longitudinal cooling channels in the mould. In addition, a vacuum line passes through the connector casing from the floor of the mould to the outside. In order to design a cooling unit of this kind in which the conditions at the moulding-station enclosure cooling unit have no influence on the admission of cooling air to the connecting casing and hence no influence on the cooling of the IS or RIS machine moulds, the cooling-air supply line to the connecting casing is directly connected to a cooling-air supply for the IS or RIS machine.

Title: Torque transfer device with two rotatable flywheel masses - quickly releases torque before delayed build-up
Inventor: REIK WOLFGANG DR
IPC: F16D3/80
Filed: 1991-04-12
Abstract: The torque transmission device to be provided in the drive train of a vehicle between the engine and gearbox has at least two flywheel masses which rotate relative to each other.

Hydraulic control devices (400) can be provided to rapidly release a flow cross-section in the event of a rapid rise in the pressure in the pressure medium circuit through relative rotation between the flywheel masses, and then to reduce one or the flow cross-section more slowly. USE/ADVATNAGE - Optimum damping and economical production of vehicle clutch.
