Title: Gastight food container with sealed lid - having weak outer seal between container and strong foil inner seal
Inventor: MACK ULRICH
IPC: B65D51/18
Filed: 1975-08-04
Abstract: Gastight packaging, esp. for edible fats such as margarine, consists of a deep-drawn container, a deep-drawn, press-in lid. and cover foil which can be sealed to the peripheral flanges, of both container and lid. Different matls. and/or sealing conditions are used for the two seals, causing the outer seal between the cover foil and container flange to be easily opened.

Title: Coke oven charging car - for preheated coal has telescopic charging tube and ball-jointed feed tube for efficient seal
Inventor: SCHULTE FRITZ DR
IPC: C10B31/04
Filed: 1975-03-07
Abstract: A coal charging car to fill preheated oil in the chambers of a coke oven battery has a charging tube which is designed as an intermediate telescope and can be lowered to seal against a feed tube. The latter is suspended, freely movable in space, from a C-shaped carrier and can be set down on the charging hole frame. A spherical joint connects the bottom end of the telescope to an annular sealing flange. In spite of the higher excess pressure in the charging hoppers when they contain preheated coal the aegress of dust and gases into the environment during the charging operation is reliably prevented. Discrepancies in the alignment of charging hole and charging tube are thereby compensated.

Title: Ion generator for improving environmental air - has low space charge for uniform and constant ion concentration
Inventor: GOSSEL DIETER DR ING
IPC: H01T23/00
Filed: 1976-05-21
Abstract: The ion generator which generates positive and negative ions for improving the climatic conditions within a r rom, ensures good distribution of ionised air necessary for comfort. The air is charged with ions also at greater distances from the generator and the ion concentration in air does not fluctuate with time. The air passing through a channel of symmetrical cross section is ionised within channel by separate generators with low space charge. This air leaves the channel after dilution and after subsequent mixing and the elimination of any residual space charge. Corona discharge units (5, 6) are used for generating atmospheric ions. The discharge units have rotationally symmetrically, aerodynamically shaped insulating bodies. The insulated bodies enclose pref. metallic discharge tips (8, 9). The effective tip length can be adjusted by displacing the tip in the bore.
