Title: Management system for piston internal combustion engines, especially spark ignition engines of motor vehicles
Inventor: HELD VEIT DR ING
IPC: F02D41/32
Filed: 1993-08-11
Abstract: A management system for piston internal combustion engines, especially spark ignition engines of motor vehicles, for the adjustment of important control variables, principally advance angle, duration of injection and throttle position, as a function of the respective load point, is characterised in that the cylinder internal pressure, to be measured during the compression phase in a plurality of discreet angular positions of the crankshaft, serves for determining the respective load point and hence the load variables. A load variable determined in this way makes it unnecessary to resort to the not very suitable measured variables, inlet manifold pressure or air mass flow/speed, hitherto used. The essential advantage resides in the fact that the cylinder internal pressure is very closely proportional to the respective load point and permits engine control of individual cylinders. <IMAGE>

Patent DE-4333247-A1 (DE)
Inventor: BUEGENER FRANZ
IPC: E04D13/14
Filed: 1993-09-30
Abstract: The invention concerns a plastically deformable covering with at least one section (1) capable of extending in a given direction, the covering being intended particularly for use on buildings. The covering consists at least partly of a ductile, low-thickness material. The extensible section (1) has folds (5) running at right angles to the direction of extension (4), the strips (6, 7) on each side of the folds being essentially parallel to each other and to the surface of the covering. The strip (6) on one side of each fold is narrower than the strip (7) on the other side. In order to design a covering which will ensure a watertight seal over the space between a smooth surface and a larger surface, which has at least one section capable of extending in a given direction to at least twice its length and through which liquid cannot seep by capillary action into the space below covering, the invention proposes that the wider strip (7) is about twice as wide as the narrower strip (6), that the folds (5) lie immediately adjacent to each other and that they are joined to each other to form a watertight seal along one of the edges of the cover running in the direction of extension (4).

Title: Heat pumping solar collector
Inventor: BECKER FRIEDRICH
IPC: F24S10/95
Filed: 1994-01-14
Abstract: Plane solar collector in a thermally isolated casing (1,19) with a radiation permeable top plate (2,22) uses a heat carrier fluid of two or more components of differing b.pts. which can be vaporised at the operating temp.. An auxiliary gas is used, and the heat carrier fluid of a high proportion of lower boiling component, flows as a thin film along the underside of the top plate (2,22) which has a thin fibrous or porous coating. The carrier fluid is stored in a collecting vessel (18) at the lower end of the top plate, and is pushed from here by pressure fluctuations into a collecting vessel (10) through a pipeline (16) and a valve (11), and then through a valve (9) into a relatively loose porous or fibrous layer (6,27) which has a more tightly packed porous or fibrous layer (5,24) above it. The layer has thermally isolating elements, e.g. hexagonal or quadratic honeycombs (4,21) which can be made from polycarbonate; these elements have gas flow openings (20) on their lower ends and a thin fibrous or porous coating, enabling the carrier fluids to rise by capillary action. The vaporised components of the carrier fluids flow to the lower end of the collector and behind the porous or fibrous layers (5,24) and (6,27), giving up heat. The less volatile components condense and are taken up by these layers, the remaining vapour components evolve heat in an external heat exchanger (14), with a non-return valve (13) on the outlet, at a desired temp.. A mixt. of gaseous and liq. components of the carrier fluid is fed in a coiled pipe (12,23) behind the layers and collected in a vessel (8), partially filled with auxiliary gas, from where it flows through a non-return valve (7) on the underside of the top plate.

Title: Junction connector for a wide range of wire sizes
Inventor: KOURIMSKY FRIEDRICH JOSEF ALOI
IPC: H01R4/24
Filed: 1994-08-04
Abstract: A junction connector (2) comprises a number of contact connections (6) which are arranged alongside one another, penetrate the insulation and have a first contact section (36) for large wires and a second contact section (38) for small wires. The first contact section (36) and the second contact section (38) are in each case aligned with one another and are connected at a central point to a supporting strip (45), the supporting strip (45) connecting to one another (in an integral manner) the number of connections (6) which are arranged alongside one another. A thin wire (8) is electrically connected to the connections (6) by positioning it over the first contact section (36) and the second contact section (38) in such a manner that the wire end (58) rests against a rear wall (14) of the connector. A covering element (18) which has a blanking member (26) can then be closed over the wire (8) as a result of which the wire is forced into contact slots (46 and 50) in the first contact section (36) or the second contact section (38). The small wire (8) thus makes ideal electrical contact with the smaller contact slots (50). A relatively large wire (9) is connected in the same manner but makes ideal electrical contact with the relatively large contact slots (46) in the first contact section of a further connection (6). In this way, a large range of wire sizes can be electrically connected using the junction connector (2). <IMAGE>

Title: Circuit arrangement for supplying DC load, such as personal computer, from AC mains
Inventor: WALTERFANG HEINRICH
IPC: H02J7/34
Filed: 1994-09-30
Abstract: A circuit to supply a DC load from the AC mains uses rectifiers (3) and a buffer battery (8). This is in parallel with the load (5) and in the same branch there is a control circuit (10), comprising a charge current limiter (11). Parallel to this is a discharge circuit (12). The resistance in this path is negligibly small so that the discharge current remains effectively unlimited in magnitude. The charge current limiter is an electrically controlled potentiometer which opens with decreasing current. It may also be a semiconductor switch and the control circuitry will then contain a temperature sensor, which operates a cooling fan according to the temperature of the semiconductor.
