Title: Oil spillage recovery system with granular absorber - uses floating net to form pumpable solid of oil and absorber
Inventor: MACK ANTON
IPC: E02B15/04
Filed: 1977-06-18
Abstract: An integral, oil impregnated solid is formed which can be handled by pumping or scooping. The solid formed is prevented from disintegrating and floating away by enclosing fencing which is readily applied. The system consists of buoys, net, ballast elements, support rods and shock absorbers. Spacers are fitted between the support rods which act as flexible guides and spacers. The net may be made of hemp, steel or plastics or plastics coated fabrics. The net mesh is matched to the size of absorbing material granules preventing escape of granules.

Title: Continuous reading fuel consumption gauge - has venturi vacuum depression sensor signal related to vehicle speed working in conjunction with carburettor of normal type
Inventor: SANDHAGEN JUERGEN
IPC: G01F9/00
Filed: 1977-07-08
Abstract: The fuel consumption meter consists of a conventional carburettor (2) to which is connected a vacuum gauge (6) at the narrowest point in the venturi tube of the air inlet (3). A transducer (7) produces an electrical signal which is proportional to the square of the air throughput, which in turn is proportional to the fuel consumption. The signal is fed to divider (8) which also receives a signal (9 which is proportional to vehicle speed. The result of the computation by the divider stage is in the form of an electrical signal (10) which represents the fuel consumption per unit of distance travelled by the vehicle, e.g. per 100 km. This is displayed on an indicator (11). The case of constant-pressure type carburretors, the take off point for vacuum measurement is positioned between the throttle butterfly and the needle valve assembly.

Inventor: NABHOLZ HANS-ULRICH DR
IPC: B01D5/00
Filed: 1979-01-05
Abstract: In the method, which is particularly suitable for drying electrical apparatuses, the article (2) to be dried, for example a transformer, which has been introduced into an autoclave (1), is heated by the condensation heat of a part of the vapour flow formed in an evaporator (3) from easily volatile liquid, and the water vapour from the article (2) to be dried as well as the air which has penetrated is transported by the solvent vapour flow into a two-part condenser (4), in which water vapour and solvent vapour are condensed and the air is drawn off by a vacuum arrangement (72). Provided in the first condenser part (4') are cooling pipes (b) of a preheating system (b3, b, b4) and in the second condenser part (4'') are cooling pipes (h) for a cooling medium. The solvent condensate, which arises in the collecting container (5) from the second condenser part (4'') and is separated from the water, as well as the solvent condensate from the autoclave (1) are conducted into the preheating system (b3, b, b4), thus preheated and supplied to the evaporator (3), as a result of which an extensive recovery of the cooling heat and thus also a reduction of the consumption of cooling medium are guaranteed. <IMAGE>
