Title: Ultrasound-recyclable, microwave-curing adhesive systems with intumescent or nonintumescent characteristics
Inventor: GROSE-PERDEKAMP HEINZ-JUERGEN
IPC: C09J9/00
Filed: 1993-04-30
Abstract: The invention enables the use of microwaves for the curing of adhesives which intumesce during the curing process, with even relatively large cavities or interstices in the components to be bonded being completely filled. After cooling, the bonded, finished components can be subjected immediately to mechanical loading. If the complete filling of cavities or interstices during the adhesive bonding operation is unnecessary, or if the expansion of the adhesive is undesirable owing to formation, associated therewith, of air pores, then the adhesive formulations can be modified such that intumescence is suppressed.

Title: Hydraulic fan drive for a cooling system of an internal combustion engine
Inventor: MAXEINER THASSILO
IPC: F01P7/04
Filed: 1993-06-30
Abstract: The invention relates to a hydraulic fan drive for a cooling system of an internal combustion engine, which can be cranked by means of an electrical starter. Known hydraulic fan drives of this type comprise a hydraulic pump and a hydraulic motor, which can be supplied with pressure medium from the hydraulic pump by way of a pressure line, by which motor a fan wheel can be driven at a speed variable as a function of the temperature of a coolant. In order to limit the power consumption of the fan drive in warm starting of the internal combustion engine and thereby to spare the electrical starter and the battery usually feeding the starter, it is proposed that it be possible to feed a quantity of pressure medium to the hydraulic motor during the on-time of the starter which is smaller than the quantity of pressure medium corresponding to the temperature of the coolant. The quantity of pressure medium fed to the hydraulic motor is preferably zero during the on-time of the starter so that the hydraulic motor does not turn.
