Patent DE-2351840-A1 (DE)
Title: Flat bar cooling bed stacking arrangement - moves bars stagewise by throwing first bar into second stage
Inventor: KIRCHHOFF HANS
IPC: B21B39/00
Filed: 1973-10-16
Abstract: This stacking and cooling mechanism is used for simultaneous cooling and stacking of flat bars after rolling. The stacking process is simplified in comparison with conventional equipment in which the cooled flat bars have to be separately stacked into stacks of required size after cooling by separate operation. The cooling bed arrangement has a number of shallow steps so that it can accommodate flat bars of different widths. The bars arrive in the depositing trough and are lifted into the first stage of the cooling bed. Bars are actuated by the cylinder and piston assembly and shuffled into a stack which when complete is pushed further along the bed into a third groove and hence as a complete stack over the whole width of the bed.

Title: High speed paper sheet dispenser for office machine - has low inertia friction wheels engaged by selenoid action
Inventor: LIS GERHARD
IPC: B65H3/06
Filed: 1974-02-28
Abstract: The paper supply for a copying or similar office machine is stacked in a tray. The lowest sheet of the stack is in contact with a revolving drum which is located below the leading edge of the stack. An inside rim on either side of the drum drives two friction wheels when they are moved radially outwards. This is achieved by operating a solenoid which is linked to a lever and shaft. When the solenoid, governed by the machine working cycle is energized, the two friction wheels come into contact with the lowest sheet and thus pull it out from underneath the stack. As it leves the tray, it is carried by transport ribbons to the required destination.

Title: Motor vehicle IC engine - has auxiliary cylinder worked by vapourised cooling fluid from main engine
Inventor: RENNER EWALD DIPL ING
IPC: F01K23/14
Filed: 1974-03-23
Abstract: The engine is cooled by trifluortrichlorethane which has a suitable boiling point. The liquid passes from the cooling jacket of the main engine cylinders to a heat exchanger in the exhaust pipe after the catalytic after burner. It is evaporated in the heat exchanger and taken to a vapour engine cylinder through a regulating valve. After expanding and doing work in the cylinder it passes to a condenser and the condensate is returned to the engine cooling jacket by an engine driven pump. The piston of the vapour cylinder is coupled to the same crankshaft as the main engine. The considerable heat present in the exhaust is thus used to increase the output from a given quantity of fuel.
