Patent DE-2750780-A1 (DE)
Title: Palletised load stretch wrapping machine - has compensation mechanism for sheet irregularities caused by rectangular pallet
Inventor: CERF ALAIN
IPC: B65B53/00
Filed: 1977-11-14
Abstract: The stretch-wrapping machine encloses palletised loads in sheet material. A compensation mechanism is provided to counteract the effect of irregularities caused when pulling the sheet off the storage roll, due to the rectangular shape of the pallet or the reducing roll diameter. Typically this can be effected by a jockey roller (4) on a swing arm, and on which a constant force acts. The braking torque on the storage roll (2) can also be reduced in a predetermined proportion to the deflection angle of the roller.

Title: Lubricating system for rotating machine - has sprung plunger forcing extra grease into bearing when latter overheats
Inventor: HAGENLOCHNER WALTER
IPC: F16C33/66
Filed: 1979-05-15
Abstract: The lubricating system for a vehicle generator has a radial or axial hole (17) in the bearing hub (11, 16). A plunger (18) is located in this hole and moves along the hole when the temperature of the bearing increases. The movement of the plunger forces extra lubricating grease (21) into the bearing. The extra grease is located between the plunger and the bearing. The plunger is bonded into the hole by adhesive (e.g. wax) that melts at a given temperature (= the overheating temp. of the bearing). A spring (19) behind the plunger causes the plunger to move along the hole. Injecting extra grease in this manner increases the life of the bearing.
