Abstract: The invention represents an evaporation and/or precipitation measuring equipment, which can measure with high-accuracy, continuously and automatically the evaporation of an open water surface and simultaneously eventual precipitation. The value of evaporation, which is defined as the decrease of the water level of a standard evaporation measuring vat, is measured by the equipment with the quantity of water necessary to compensate the original level. Precipitation on the other hand is measured with that quantity of water which needs to be let out in order to restore the original water level of the vat. The high accuracy can be obtained on the one hand by adjusting deliberately small feeding resp. lower quantities. On the other hand the sensing unit of the equipment watches the water level of the evaporation measuring vat with high accuracy, and controls the supply and lower units respectively when the level varies due to either evaporation or precipitation.

Abstract: An auxiliary fuel system for installation beneath the rear portion of the floor pan of a passenger car. The auxiliary fuel tank in the system is resistant to leakage even when the car in which it is installed is subjected to a rear end collision. The system increases the survivability of the auxiliary fuel tank by the use of transversely extending support straps which permit the longitudinal forward and downward movement of the auxiliary tank during said collision, to thereby help prevent its being crushed. The tank's ability to move downwardly as it moves forwardly during said collision is enhanced by the tank being provided with a sloping front wall which deflects the front of the tank downwardly as it encounters a transverse member in the car, and by the tank also being provided with a large, relatively shallow fuel storage area designed to bulge during said collision, thereby also tending to force the tank downwardly away from the car.

Abstract: A lubricating system for automotive components includes an oil reservoir to supply an initial charge of lubricating oil upon cold starting of the engine, with provision to maintain the reservoir in a full attitude after the engine lubricating oil has warmed and is freely circulating, thereby preserving a charge of oil available for the next cold starting of the engine.

Abstract: This invention is concerned with a method and apparatus for the development of photographic films in a photographic film processor in which the films are developed when the exposed films pass through a developing tank containing developer. The object of said invention is to attain uniform development with a simple method, that is, to make the change of the activity of the developer during the development of the films to be treated very small from the leading end to the trailing end of the film. The said invention makes the influence of the momentarily changing activity of the developer in contact with the films as small as possible by compensating for the decrease of the activity due to the exhaustion of the developer by gradually increasing the immersion time of the films in the developer from the leading end toward the trailing end of the photographic films by gradually changing the relative level of the liquid surface when the films are fed into the developer.

Abstract: The invention pertains to a conduit assembly consisting of a flexible hose having a self sealing valved fitting at each end, such assembly being suitable for interconnecting aircraft fuel cells. The assembly is crashworthy in that upon displacement of the fittings relative to each other the resultant tension force produced in the hose causes the valves within the fittings to automatically close prior to the rupture of the hose thereby minimizing the likelihood of fuel spillage and fire. Frangible elements within the fittings fracturable upon predetermined hose tension forces existing insure the desired sequence of valve operation without requiring complicated apparatus, cables or links which would interfere with the flexibility of installation.

Abstract: A powered aircraft has a jettisonable fuel tank releasably secured in the bottom of its fuselage. A valve is arranged to shut off fuel flow from the tank upon releasing of the tank from the fuselage, whereupon a parachute connected to the tank is released to slow the descent of the tank. Additionally, a reserve fuel tank in the fuselage is normally connected to the jettisonable fuel tank, and the valve is so arranged that fuel flow communication is normally maintained between the jettisonable fuel tank and the aircraft engine while fuel is prevented from flowing from the reserve tank to the engine. However, when the jettisonable fuel tank is released from the fuselage, the valve shuts off the flow of fuel from the jettisonable fuel tank and establishes open communication between the reserve tank and the engine to permit continued operation of the aircraft under power of the engine.

Abstract: The film developing machine includes a tank containing developing fluid, to which a dosing device continually adds regenerating fluid received from a regenerating-fluid supply tank. To prevent the gradual emptying of the supply tank from producing an accuracy-reducing gradual decrease in the pressure applied to the input side of the dosing device, the latter is connected to the supply tank via a buffer vessel provided with an internal valve mechanism serving automatically to keep the volume of regenerating fluid in the buffer vessel substantially constant despite variations in the amount of regenerating fluid contained in the supply tank.

Abstract: The apparatus comprises a first chamber in which there is present a gaseous or vaporous medium under pressure and a second chamber which is predominantly filled with a liquid medium under a pressure independent from the pressure in the first chamber. In addition to these two chambers an intermediate chamber is filled in normal operation with substantially the same gaseous or vaporous medium at substantially the same pressure as present in the first chamber. The first chamber is connected through ducts via the intermediate chamber with the second chamber and at normal operation an unavoidable predetermined pressure drop is caused between said intermediate chamber and said second chamber. The pressure regulation is effected by a piston-operated shut off device adapted to assume an open and a closed position which device is disposed between the first and second chamber.

Abstract: Disclosed is an assembly including a dump tank disposed near the fill pipe for an underground gasoline storage tank at an automobile service station. The tank is normally isolated by a hand valve and a check valve from communication with the storage tank fill pipe, however, when the storage tank has been filled from a transport vehicle, the gasoline in the fill pipe and the flexible delivery hose may be dumped into the dump tank by opening a manually operated valve. The check valve permits gasoline thus dumped to flow from the dump tank back to the storage tank as gasoline is pumped from the storage tank during normal pump operation of the service station.
