Patent DE-2115000-A1 (DE)
Title: Rotary heat exchanger seal - has sealing pressure compensated as rubbing layer becomes thinner
IPC: F28D19/04
Filed: 1971-03-27
Abstract: A sealing element fora heat exchanger with thermal storage and transfer rotor, consist of a sealing plate with anti-friction layer and a chamber formed by a corrugated tube. The chamber communicates with the upper face of the anti-friction layer through a duct, which passes through the anti-friction layer in such a direction that as the mouth of the duct wears away and the layer becomes thinner, the mouth moves towards the zone of higher pressure. This movement leads to higher pressure inside the chamber, which compensates for the reduced elastic force exerted by the corrugated tube.

Title: Automatic cream beater
IPC: A47J43/12
Filed: 1971-04-17
Abstract: Automatic beater with interior bell supplied with cream and compressed air which are controlled by means of a flip lever in the top of the bell. Each end of the lever has a small bar which carry the bungs used to close off the cream and air entry lines to the bell. The cream stiffening under the effect of the beater wheel in the bell trips two flaps carried below the lever so as to operate the lever through an arm and thus unstop the air line but close off the cream line and allow the cream now beaten or whipped to required consistency to be withdrawn from the process bell. The cream thus has no time to build up at the top of the bell and block the apparatus.

Title: Football-type game using TV -screen display - offers players more excitement than a known similar table-tennis game
Inventor: HECKER KLAUS J DIPL ING
IPC: A63F9/00
Filed: 1974-04-10
Abstract: This football-type game is played by two or more players using a display on a TV screen. Electronic circuitry reckons the position digitally by counting the lines and the conventional 'steps' along the lines, of the TV raster. The circuits generate a 'ball' and touch lines from which the bal ball 'bounces' (a position counter switches from add to subtract or vice-versa). Gaps in the touch lines denote 'goals'. The 'ball' passing through them goes out of play. Each player has a symbol which he can move about the TV screen with potentiometer knobs and also cause to 'kick' the 'ball' away from itself at a speed inversely proportional to the distance between the symbol and the 'ball'. After each 'kick' the player must wait a certain time before he can 'kick' again.
