摘要:
A fuel tank, for a vehicle or heating plant, includes a flexible air container therein, forming a fuel space outside the air container. The air container seals the interior of the fuel tank to the exterior and the fuel vapors in the fuel tank are drawn off and directed into the engine and burned. The vapors can be so drawn off by the vacuum produced by the engine, or by a pump. Fresh air from the exterior is drawn into and through the air container and directed into the fuel mixture for combustion, clearing out any vapors that may have collected in the air container. A filter is controllably utilized for adsorbing, or absorbing the vapors, and fresh air is controllably drawn into the filter for clearing those vapors out and directing them into the fuel mixture for combustion.

Structurally strong, investment quality gold articles of high troy weight, excellent color and revealing properties and the method of their production are described, including the formation of a structural base from an alloy containing not over 8% of a strengthening material such as chromium, titanium or vanadium, which can provide the required strength and hardness in low concentrations, and overlayment or "overaching" with a gold alloy coating in a manner such that both alloys are visible. The structural base provides the support, strength and resistance to corrosion in articles of various shapes, while retaining a high degree of gold fineness.

A mixer-unit is attached to the cold and hot water mains and serves to adjust the quantity and temperature of the water. The mixer unit is not fitted with an operating handle or lever, the adjustment of the water quantity and temperature is achieved by pivoting the water outlet about two independent axes of movement. Disc-shaped regulating elements serve for the independent adjustment of both the water quantity and temperature which are operable by means of a cam connected to the rotatable and pivotable water outlet.

In electrolysis installations which possess in a common tank a plurality of anode and cathode plates electrically connected one behind the other, uniform supply to or flow through the individual cells is of greatest importance. According to the invention, the inflow, but also if possible the outflow, is placed below the liquid level, and a distributor pocket for uniform distribution of the liquid is connected between the inflow or outflow of the liquid and its entrance or exit from the electrolytic tank, respectively. For optimum adjustment of the chemical and physical constitution of the liquid, flow-independent measuring and adjusting of the liquid is achieved by a sensor which is arranged in a by-pass to the cycle line of the etching fluid between the etching tank and the electrolytic cell.

Ammoniacal etching solution containing metal ions as the result of etching is withdrawn from an etching bath and while part of it goes to an electrolysis cell for removal of metal ion, the remainder goes back to the etching bath through a liquid jet pump in which it serves as the working liquid, while the pump sucks in from the electrolysis cell the anodically evolved oxygen. The thorough mixing of the oxygen into the etching solution performed by the pump results in oxidation so rapid that in many cases it becomes unnecessary to suspend catalyst particles in the electrolyte to accelerate the oxidative regeneration of the etching solution. Where use of such particles is still desired, the solution drawn from the etching bath goes through a cylindrical filter unit from which a filtrate is drawn off laterally for the electrolysis cell, while the remainder of the input goes to the jet pump. Controls are provided for using the electrolysis cell only when the metal ion concentration is above a predetermined value, for adding ammonia to the oxygen line in order to maintain a particular value of pH and for controlling the temperature of the electrolyte in the electrolysis cell in order that a desired quantity of water can be condensed from the oxygen line for use in rinsing the work pieces after they are taken out of the etching bath.

A circulator pump for a plant for the utilization of solar heat including a first heat exchanger for collecting heat at a high level disposed within a solar collector, a medium for receiving heat collected in the first heat exchanger, a second heat exchanger for collecting heat at a lower level with respect to the first heat exchanger and a circulator pump for circulating the medium through the first and second heat exchangers. The circulator pump is a prime mover driven by a pressure difference between the first and second heat exchangers and is a charger pump. The prime mover and charger pump operating in a push-pull manner as differential piston pumps having a common piston rod operatively disposed within a chamber including control ducts, which load an auxiliary control slider member. The auxiliary control slider member is reciprocated within a chamber and upon reaching end portions of the differential piston switch the chambers of the two differential piston pumps to effect oppositely directed movement.

The invention pertains to an adaptor for inserting lamps with pin bases into screw bases, the task of which is to make it impossible to screw out the adaptor without special tools after it has been inserted into the screw base. This task is achieved by the invention by arranging the thread of the adaptor on a loosely rotating threaded bushing which can be rigidly connected with the adaptor body by means of a key before screwing in the adaptor. After the adaptor has been screwed in and the key has been removed, the threaded bushing cannot be removed from the socket.

The method for stabilizing the voltage of an AC generator with varying (alternating) rotor speed is characterized in that the voltage generated by an AC generator is maintained constant when the rotor speed changes. The control is carried out without the use of electrical contacts by means of a high-frequency pulse generator. The transformer of the high-frequency pulse generator is divided. The rotating part is provided on the rotor axis and the other part is stationary outside the rotor. Both parts are separated by an air gap. Deviations from a preset output voltage are controlling the pulse generator whose pulses are transmitted by the transformer to the power section of the rotor. The complete power section consisting of the coil and the electronic switch is arranged on the rotor so as to transmit only control currents without physical contact.
