Title: Fuel tank for rocket motor - is connected to smaller tank which collects residual fuel for further use
Inventor: SIMON MICHAEL DIPL ING
IPC: B64G1/40
Filed: 1991-04-18
Abstract: The rocket motor which operates on liquid fuel has a main tank (10) in which the fuel is stored.

Patent DE-4120679-A1 (DE)
Inventor: WENSKE HANNO DR ING
IPC: C25B9/19
Filed: 1991-06-22
Abstract: The invention relates to an electrolytic cell and a capillary slit electrode for gas-developing or gas-consuming electrolytic processes and reactions, and an electrolysis process therefor. According to the invention, the capillary slit electrode (2, 3) has conduits (10, 13, 11, 11') enabling the separate flow of reaction gas and electrolyte/permeate in the electrode. The electrode is preferably hydrophilic in a narrow internal region (10, 13) for mounting on a separator, while elsewhere (11, 11') it is hydrophobic. Thus electrolyte/permeate penetrates only into the region of the capillary slit electrode near the separator, while the region away from the separator remains free of electrolyte/permeate, so facilitating the unimpeded flow of the reaction gas. The invention is applicable especially in electrolytic cells for chlor-alkali or hydrogen electrolysis, and in the construction of cells for the generation of electric power.

Patent DE-4136333-A1 (DE)
IPC: E06B5/16
Filed: 1991-11-05
Abstract: A fire-proofing glazing (1a) is composed of two panes (2) spaced apart by spacers (4, 6) and a fire-proofing foil (25) wound on a shaft (22) in the upper spacer (4). The fire-proofing foil (25) is secured with its outer longitudinal marginal zone (27) to a plate-like traction weight (28). The traction weight (28) is fixed in position in the upper spacer (4) by means of a meltable positioning material (31). In the event of a fire, and once the positioning material (31) has melted, the traction weight (28) filled with a drying agent (20) is pulled downwards by the force of gravity and unwinds the fire-proofing foil (25), which thus forms between the panes (2) a shield that is inflated when a determined temperature is reached. Instead of the wound fire-proofing foil (25), a folded fire-proofing foil may also be used.
