Abstract: The invention relates to a method for establishing a telephone connection between a caller and a party to be called via a service provider. According to said method, the caller establishes an Internet connection to the service provider with the aid of a data processing unit and transmits information identifying both the caller and the party to be called to the service provider via the Internet connection. In response, the service provider makes available a transmission path for the telephone connection, by analysing at least the information identifying either the caller or the party to be called in accordance with a predefined criterion and by transmitting selected information, depending on the analysis result, to at least one of the parties via the Internet connection and/or the transmission path.

Abstract: A method for manufacturing a pressurized two-chambered container in the form of an aerosol can, in which a housing is provided with an opening that can be sealed tightly by a spray or aerosol valve. A product chamber and a propellant chamber are formed separately fluid-tight from each other by a flexible diaphragm in the housing. The product chamber can be charged with a product which can be release through said valve. The propellant chamber can be charged, on the other hand, with a compressed propellant. The product chamber communicates with the product-release opening. At least one end of a blank is left open to constitute subsequently the housing. The diaphragm is inserted into the blank through the open end, and the blank then is formed into the housing. An edge of the open end of the blank is reformed to narrow it into an integral mouthpiece that accommodates the product-release opening.

Abstract: The invention provides the possibility of reducing the size of a mobile phone (1) by reducing the key set (7, 11, 12, 13). The invention provides a system and a method for mobile radio transmission by means of a mobile unit (1) which, for setting up a connection, has only one or more direct connection keys (7, 11, 12, 13), the initial activation of which in each case sets up a connection to a destination location assigned to one of the respective direct connection keys (7, 11, 12, 13). By activation of a central key (7) of the mobile unit (1), a connection (33) from the mobile unit (1) to a central switching device (30) is set up.

Abstract: The oilpan of a low-noise crankcase is bolted to the downwardly extending ankcase sidewalls and has omega-shaped crosspieces extending transversely to the oilpan sidewalls and to the sidewalls of the crankcase, and the crosspieces are in alignment with the main bearing walls of the crankcase. The crosspieces form part of the oilpan and are connected to its sidewalls in such a manner that forces are propagated, the sidewalls being reinforced as compared to the bottom of the oilpan which is not reinforced. The oilpan is bolted to the crankcase by additional bolts located in pockets in the crosspieces on both sides of the cylinder axes, and are attached to the crankcase as far away from the outer walls thereof as possible.

Abstract: The present invention relates to an internal combustion, reciprocating pin engine with a piston which, on its up-stroke, sucks air or a fuel-air mixture via a flap valve or a similar device into the space beneath its base and, during the down-stroke, sends the then compressed gas via another flap valve or a similar device and a connecting passage to the inlet control ports of said internal combustion, reciprocating piston engine. The pump space of the piston pump which is formed by piston, cylinder liner and annular slide comprises an inlet passage and an outlet passage, equipped with diaphragm valves, respectively.

Abstract: A two-stroke internal combustion engine of the crankcase scavenging type, in which a nozzle connected to a lubricant feed line is provided in the intake passage for picking up oil from a lubricant reservoir via a partial vacuum. For simple and sufficient lubrication and cooling of the crank gear in accordance with the respective requirements of the engine, the nozzle (62) is positioned in the area of the smallest cross-section of a Venturi-tube-like part (60) of the intake passage, and an injection pump (54) is provided for fuel delivery, which eliminates the need for an oil pump.

Abstract: A known feature of internal combustion engines is that the cooling-water pump has an impeller which is rigidly connected with a squirrel cage rotor and which is driven without physical contact via the rotatory field of rotating permanent magnets. If such an engine is additionally provided with a flywheel generator, construction of the cooling-water pump is greatly simplified according to this invention, as the permanent magnets of the flywheel generator are simultaneously utilized for driving the impeller, and the water pump is positioned in a concentric recess of the flywheel, thereby saving space.

Abstract: A lubricating oil pump for a four-stroke internal combustion engine inclu a pump body; an annular gearwheel rotatably mounted around the outer perihery of the pump body, the annular gearwheel including projections on its outer surface to function as cams for valve control and including teeth on its inner surface; and a driving pinion mounted within the annular gearwheel and attachable to the crankshaft of the engine, the driving pinion including external teeth in meshing engagement with the internal teeth of the annular gearwheel such that the annular gearwheel rotates at half the speed of the driving pinion.
