Title: Oil fire extinguishing system - uses vertical pipe at outlet increasing distance of flame from it
Inventor: GABRIEL ANDREAS
IPC: E21B35/00
Filed: 1991-04-10
Abstract: Fires, particularly oil fires, are extinguished using a vertical pipe at the flame outlet. This increases the distance between the flame and the outlet, giving a cooling effect on the area immediately adjacent to it and aiding active measures for cooling. Re-ignition of the outflowing medium by the remaining flame can be prevented after the pipe has been removed, also sideways escape of the medium at the pipe bottom end. Equipment can be provided for combustion of the medium with the minimum amount of residue, and there can be ignition equipment at the top pipe end. ADVANTAGE - Rapid extinguishing of oil well fires in particular, using only small amounts of coolant and extinguishing agent.

Patent DE-4130446-A1 (DE)
Inventor: WELLER ALBRECHT DR
IPC: A47J31/10
Filed: 1991-09-13
Abstract: In a first embodiment the beverage brewing machine (1) has a reservoir (3) in which water is heated, fitted above a brewing unit (2) and heatable by an electric heating device (5). At the bottom (4) there is an outlet valve (11) which opens only on reaching a given water temperature so that the hot water flows through an outlet pipe (12) downstream of the outlet valve (11) from the reservoir (3) over the upper surface (53) of a product (13), preferably ground coffee or tea-leaves, contained in a brewing unit (2), from which it goes to a recipient (31) as a beverage after extraction of the product (13). Hot water from the reservoir (3) can also be taken via a pipe (16) along other paths (27) than over the upper surface (53) of the product (13) into the recipient (31). The pipe (16) takes a siphon-like path (18), the vertex (23) of which is far enough above the bottom (4) of the reservoir (3) so that hot water also flows via the pipe (16) to the other path (27) and not only over the upper surface (53) of the product (13) only when a certain level (48) is reached in the reservoir (3). In a second embodiment, the hot water can also be taken via the other path (27) by means of a brewing head having a main and auxiliary chamber. Both embodiments make it possible for the hot water to be automatically distributed after a predetermined quantity of beverage has been brewed without the need for complex and moving valve devices. Distribution of the hot water enables as few undesired components as possible to be extracted from the product (13).

Patent DE-4212449-A1 (DE)
IPC: B01D17/02
Filed: 1992-04-14
Abstract: A barrier (B), which is alternatingly composed of permeable separating elements (2) and impermeable separating elements (1) serves to separate disperse liquid-liquid and liquid-solid systems. The permeable separating elements (2) are inclined upwards at an angle  alpha of 0 to 45 degrees with respect to the horizontal and the impermeable separating elements (1) are inclined downwards at an angle  beta  of 0 to 60 degrees with respect to the horizontal and their adjacent longitudinal edges are connected together. The proposed combination of permeable and impermeable separating elements makes possible the separation of sinkable solid particles from the actual barrier, while the inclined to horizontal arrangement of the permeable separating elements makes possible an orientation of the velocity vector of the liquid with the buoyancy force of rising drops and thus makes possible a coalescence to form large drops in the shortest path. <IMAGE>
