Patent DE-3318179-A1 (DE)
Title: Engine block, ribbed piston with displaceable bearing base, piston ring with spring and leaf valves (intake and pressure valve)
Inventor: KULL DIETER
IPC: F02B75/02
Filed: 1983-05-19
Abstract: Engine block, ribbed piston rod, piston ring and leaf valves for a four-stroke reciprocating piston compressor engine as drive unit for locomotive devices of all types. These components are to be used as a unit in a system of parts such as cylinder head, crank shaft and others. In the reciprocating piston compressor engine the cylinder and ribbed piston simultaneously performs two functions. Whilst that side of the ribbed piston facing the combustion chamber works on the conventional four-stroke principle, the ribbed rear side of the piston employs the compressor principle - intake and exhaust. The air drawn in and precompressed by a leaf suction valve thus passes through a leaf pressure valve into an air manifold of a fuel-air mixture preparation system and into the cylinder head and the combustion chamber. Since cylinder and crank casing are separated by a transverse wall, no condensates or soot constituents get into the lubricating oil. Heat problems in the area of the ribbed piston are excluded due to the constant flow of fresh air around it. The maximum charging pressure is available even from idling speed onwards. Expensive, complicated charging systems - turbo, etc. - which do not function satisfactorily in all ranges are in this case rendered superfluous. <IMAGE>

Title: Device for packing and unpacking bottles or the like
Inventor: MUELLER FRIEDHELM
IPC: B65B21/18
Filed: 1983-08-04
Abstract: In a device for packing and unpacking bottles or the like which are transferred by a gripper device in the loading and/or unloading direction along a hook-shaped path, the gripper head being arranged on the extended connecting rod of a four-bar coupler mechanism, a further improvement is to be made to permit the stream of bottles to be fed or discharged from different sides. To this end it is proposed that a four-bar coupler mechanism (5') should be arranged laterally offset in relation to the first mechanism (5) on one side of the feeding and removal plane (4), and that the crank (6) should be connected to the driving crank (19) via an intermediate articulation (18). <IMAGE>

Title: Sanitary fitting
Inventor: OBERDOERFER HANS
IPC: E03C1/04
Filed: 1983-09-10
Abstract: A description is given of a sanitary fitting which comprises an integrally cast housing. Mounted on an upward-facing connection face of the housing is a control cartridge, the outlet opening of which communicates, via a cavity extending in the housing, with the outlet. Whereas, in known fittings, the inflow of the water to the connection face takes place at least partially through bores in a residual area of housing material forming an island surrounded in the manner of a ring by the cavity and the inlet pipes are secured on or in these bores, the cavity in the fitting according to the invention is continuous, i.e. is not annular. The inlet pipes themselves pass through the cavity and are sealed off on both sides from the latter. In this way, it is possible to manage with a single, simple core when casting the body of the fitting.

Title: Fuel injection device
Inventor: TSCHOEKE HELMUT DR ING
IPC: F02B3/06
Filed: 1983-09-24
Abstract: Fuel injection device with pre-injection and main injection for internal combustion engines, especially diesel internal combustion engines. A high-pressure injection pump simultaneously supplies a main injection nozzle (40) with a main injection quantity and drives a hydraulic pre-injection auxiliary pump (10), which contains a pre-injection piston (23) and a working chamber (20) arranged in front of this and supplied with fuel from a separate low-pressure feed pump. At the same time the pre-injection piston (23) is supported so that it can slide in a bore (22) of an accumulator piston (15), which in turn is supported so that it can slide in a bore (12) of the pre-injection auxiliary pump (10). Inside the accumulator piston (15) corresponding transverse bores (19, 27) are located, which communicate with the pressure and working chambers (20) for the pre-injection piston (23) and are connected with fixed inlets (16, 17) in the housing (11). A transverse bore (44) in the accumulator piston (15) is so arranged that the inlet to the main nozzle (40) is opened by the stroke of the pre-injection piston (23), the fuel delivered by the high-pressure injection pump initially passing into a pressure chamber (43) defined by the accumulator piston (15). The main injection is thereby delayed until the accumulator piston (15) is displaced to an adjustable stop (25). All times and injection quantities of the pre- and main injection are adjustable independently of one another. <IMAGE>

Title: Covering of buildings which are subject to solar or heat radiation, especially for greenhouses, tunnels, borders or the like
Inventor: KUECKENS ALEXANDER
IPC: F24S10/70
Filed: 1984-09-19
Abstract: In order to obtain optimum absorption of IR rays in conjunction with covering elements for buildings, covering elements are used which form cavities and consist of a transparent or translucent material. Transparent or translucent surface elements are inserted into the cavities such that they divide the cavity cross-section into two chambers so that a heat-carrier fluid can be passed through both sub-chambers, which fluid flows over the surface elements on both sides. The surface elements themselves are produced from a material which contains phototropic (that is to say absorbing up to 90% of the IR rays), for example organic, salts. The covering is suitable for living rooms, for workshops and especially also for establishments for breeding cultivated and useful plants.
