Title: Slide valve for a device for gas-free broaching and closing a gas pipeline
Inventor: JESCHKE IMMANUEL
IPC: B23B41/08
Filed: 1985-06-22
Abstract: In order to be able to broach (and subsequently close again) plastic gas pipelines, two half-shells are welded to the gas pipeline, the upper half-shell having an attachment stub through which the broaching takes place. In order to make possible gas-tight broaching and gas-tight closing of the gas pipeline, a slide valve is equipped with a stub holder which makes it possible for the slide valve to be fitted in a gas-tight manner to the holding stub, to be precise without any thread being required. The stub holder has a smooth inner wall into which at least one O-ring is inserted for sealing. In addition, the slide valve is fixed in a mechanically secure manner on the attachment stub by means of spring safety hooks. The use of the slide valve in the case of plastic gas pipelines makes it possible, in a manner which is known per se for metal gas pipelines, to broach in a gas-free manner, to form a blister in a gas-free manner and to seal the hole again subsequently in a gas-free manner.

Patent DE-3643043-A1 (DE)
Inventor: MENGE HEINRICH
IPC: G05D9/04
Filed: 1986-12-17
Abstract: The evacuation of foul smelling gases from the interior of a toilet bowl is effected by a fan which is driven by an electric motor and conveys the gases from the bowl through a control chamber in the flushing tank and into an evacuating conduit which is connected to the drain pipe. The motor is started in response to closing of a master switch which is distinct and preferably remote from an actuating knob which must be lifted or otherwise moved in order to enable a body of flushing liquid to flow from the tank into the bowl. A siphon is provided to permit liquid to flow from the interior of the control chamber into the interior of the flushing tank in response to rising pressure in the control chamber. Such pressure, which rises in response to starting of the motor, causes a lowering of the liquid level in a portion of the control chamber and a rise of the liquid level in another portion of the control chamber so as to establish in the siphon a continuous column of liquid which flows by gravity from the control chamber into the flushing tank so as not to waste the liquid which normally seals the inlet for gaseous fluid from the outlet for gaseous fluid in the control chamber.

Abstract: Exhaust turbine generator unit for diesel engines, especially for green diesel engines with or without shaft-driven generator. An excess proportion of the diesel engine exhaust gases is fed to a power output turbine (2), which drives a generator (4) by way of a reduction gear (3). For energy conversion a self-excited synchronous generator (4) is provided, which by way of a bus-bar (5) with mains switch (6) feeds electric power into a mains system (7). An asynchronous starter motor (8) for starting and running up the synchronous generator (4) and the power output turbine (2) when the exhaust valve (10) is closed is provided in such a way that when the nominal slip of the asynchronous starter motor (9) is attained, the excited synchronous generator (4) is synchronised with the mains system (7), the asynchronous starter motor (9) switched off and the exhaust valve (10) opened for the purpose of delivering active electrical power and proportional reactive power from the synchronous generator (4) to the mains system (7). If system faults occur, a braking resistance (12) is instantaneously connected to the synchronous generator (4), the mains switch (6) opened and the exhaust valve (10) closed. In the event of an exciter failure of the synchronous generator (4), only the exhaust valve (10) is closed and thereafter the mains switch (6) opened. <IMAGE>

Patent DE-3708166-A1 (DE)
Title: Differential pressure valve
Inventor: LETZEL HELMUT
IPC: G05D16/06
Filed: 1987-03-13
Abstract: In a differential pressure valve, a valve cone 53 can be displaced against a valve seat 12 in the valve housing 1, via a valve rod 5, by means of a control diaphragm 3 clamped at the outside in an evacuable diaphragm housing 2, the displacement taking place counter to the action of a valve spring 7 whose prestress can be adjusted. In this arrangement, the control diaphragm 3, which is supported against a diaphragm plate 8 held against the valve rod 5, can be subjected to the differential pressure. To simplify the setting of the desired value from the outside without removing the diaphragm housing 2 and to simplify the draining function of such a valve, the proposal is to place the control diaphragm 3 provided with a hole 31 loosely but in a sealing manner against the diaphragm plate 8 in the pressure position and to displace the valve rod 5 through the diaphragm housing 2 from outside. <IMAGE>
