Title: Enamelled cooking vessel
Inventor: SCHLEGEL HANS DIPL CHEM DR
IPC: A47J36/02
Filed: 1984-07-04
Abstract: An enamelled cooking vessel and a method of producing it are indicated, which method has an improved cooking efficiency due to an improved transverse conduction of heat in the bottom and improved embossing. For this purpose, a coating is arranged on the bottom of the cooking vessel, said coating consisting of a molten mixture of a pulverised solder and a pulverised metal or an alloy. In a preferred stage of the method, said coating is produced at the same time as one of the enamelling processes; it bonds due to the soldering process to form a firm and homogeneous solid metal coating which has good heat-conducting properties and is stress-free.

Title: Method and arrangement for regulating an industrial burner with built-in recuperator
Inventor: KUEHN FRIEDHELM DR
IPC: F23N1/02
Filed: 1984-08-23
Abstract: A method and an arrangement for regulating an industrial burner (1) with a built-in recuperator (1) are described, the fuel and air inlet quanitites (VG and VL) being measured and supplied to a computer (11) and at least one control signal, which determines the mixture ratio of the fuel/air mixture, being formed depending upon the associated measurement values. Additionally, the waste gas temperature (tAG) after the the recuperator (1) and the inlet temperature (tL) of the combustion air are measured. From the said quantity and temperature measurement values (VG, VL, tAG, tL), the associated pressure loss in the recuperator is constantly determined, taking account of predetermined geometrical recuperator parameters (KR), and the mixture ratio of the fuel/air mixture is regulated depending upon this pressure loss. On removal by suction of the waste gases by an injector (26), the effective driving air mass flow is controlled in dependence on the waste gas temperature (tAG). <IMAGE>

Title: Rotary internal combustion engine
Inventor: SETOUDEH HOJATOLLAH
IPC: F02B55/00
Filed: 1984-12-27
Abstract: The invention relates to a rotary internal combustion engine with a rotary piston (II) and a housing (I, III) which has an inlet for combustion gases, an outlet for exhaust gases and a spark plug. According to the invention the housing forms an essentially circular-cylindrical internal chamber in which the piston (II) is supported so that it can pivot about the central axis of the internal chamber on its shaft (7). Together with the cylindrical wall of the housing, the piston defines at least one combustion chamber (19) which is limited by this wall and an element (15) fixed on the rotor (II) and movable between two limit positions. By means of an eccentric, closed guideway (24) which is incorporated into the housing (III) on the end face, this element is guided into its two limit positions twice for each rotor revolution, resulting in four phases of an engine, that is induction, compression, explosion and expulsion of the exhaust gases. <IMAGE>

Patent DE-3504071-A1 (DE)
Title: Method for using the waste gas heat in heating installations and heating installation for implementing the method
Inventor: DEGRO HANS
IPC: F24H8/00
Filed: 1985-02-07
Abstract: To use the waste gas heat of a heating installation, the waste gas is cooled down by heat exchange with cold fresh air until condensate is formed. The heat of the greatly heated fresh air is used in heat exchange or by direct feeding in inside the heating installation, and also for preheating the combustion air and for reheating the waste gas for the purpose of protecting the chimney. The acid condensate is made alkaline and serves as washing water for treating the cooled waste gas in order to retain from the waste gas the harmful substances, in particular SO2, not removed by condensation, the condensate being neutralised.

Title: Circuit arrangement for measuring inductances
Inventor: BRAEUNINGER JUERGEN DR RER NAT
IPC: G01R27/26
Filed: 1985-04-16
Abstract: A circuit arrangement for measuring inductances or inductance changes is proposed in which a variable inductance (6) to be measured is compared in a computer (13) with a reference inductance (7). In order to compensate for external influences, for example temperature influences, the reference inductance (7) is always re-measured when correspondingly substantial changes in the influencing quantities have been detected. Unnecessarily frequent measuring of the reference inductance (7) is thus avoided, thereby reducing in particular the jitter of the measuring parameter. <IMAGE>

Abstract: A shelf unit which can be dismantled, in particular a shelf unit for pallets, is made up of posts 1a to 1d as well as longitudinal cross beams 2 and transverse cross beams 3, which posts and beams are in each case formed from profiled metal parts. At least the posts 1a to 1d have an approximately C-shaped profile cross-section, which contains, in its wall forming the profile web, a bead which runs longitudinally and is directed into the profile interior. Provided in the web-wall sections, which lie on either side of the bead, are openings which are distributed in the longitudinal direction in the manner of a grid. At their ends, the longitudinal cross beams 2 have coupling shoes 11, which in each case run transversely to their longitudinal direction, have an approximately L-shaped cross-section and bear on their L-web suspension tongues which are directed inwards, have a grid spacing which is matched to the openings in the web-wall sections of the posts 1a to 1d and can be suspended in the openings of the posts. In this connection, the short L-flange of the coupling shoes comes to rest next to a bead side flank and the long L-flange of the same comes to rest next to a longitudinal side wall of the post 1a or 1d. It is important that each upright limiting edge of the openings in the posts has an attachment slope, which runs in an inclined manner parallel to the plane of the web-wall sections and transversely to the plane of the longitudinal side walls and of the bead side flanks and, in this connection, the coupling shoe 11 [lacuna] via this attachment slope with a [lacuna] its flanges transversely to the post surface which is adjacent to it ...

Title: Throttle valve for crude oil and natural gas conveying installations
Inventor: TEEPE STEPHAN DIPL ING
IPC: F16K47/08
Filed: 1985-05-03
Abstract: The invention relates to a throttle valve for crude oil and natural gas conveying installations for regulating a conveyed flow emerging under pressure, the valve housing of which is provided with an inlet for the conveyed medium, preferably arranged perpendicularly thereto, an outlet for the conveyed medium and with a valve body which is displaceable by a spindle and as a result of the displacement movement of which the outlet can be continuously shut off. In this case, the valve body is arranged in the valve housing in such a manner that its end face faces the conveyed flow entering through the inlet and its casing faces the outlet, the casing completely closing the outlet in the closed position of the valve body and, on opening, the end of the valve body freeing the outlet to an increasingly great extent, and the end face of the valve body bringing about the deflection of the conveyed flow striking it into the outlet and to this end having a shape which is favourable to flow. As a result of the omission of its valve seat and the flow-favourable design of the path for the conveyed flow through the valve, the life of such a valve can be increased considerably.
