Title: Reciprocating piston internal combustion engine with applied ignition and with combustible mixture formation in a mixing chamber offset from the working chamber
Inventor: TAUSEND ERICH
IPC: F02B23/10
Filed: 1993-02-16
Abstract: Reciprocating piston internal combustion engine with applied ignition and with combustible mixture formation in a mixing chamber offset from the working chamber, preferably for easily carburetted or gaseous fuels. The mixing chamber is arranged in the cylinder cover and the ignition elements centrally inside the said mixing chamber. Pure air is compressed in the working chamber and the fuel is fed into the mixing chamber during the compression phase; the energy required for formation of the combustible mixture is obtained from the working chamber. Due to the interaction of the mixing chamber elements: inlet edge (1) with release (3), neck ring (4) with neck edge (5) and turning ring (6) with guide casing (7) a loop-mix scavenging concentric with the cylinder axis is produced in the mixing chamber. The fuel is injected tangentially into the turning ring (6) during the compression phase. The mix scavenging begins at that instant when the air flow displaced from the swept volume gap (H) is applied as surrounding jet to the wall of the neck ring (4) and is deflected into the turning ring (6) by the guide casing (7). Due to the interaction of the piston control edge (21), the neck ring (4) with neck edge (5) and the guide edge (8), an aerodynamic control effect is produced which controls the start of mixing. The aim of the mixing grid (14) is to generate a micro-turbulence. The combustion reaction is intended to occur inside the central combustion zone (BZ) with the least possible wall contact. The aim is to ... Original abstract incomplete. <IMAGE>

Title: Device for fitting a wire end sleeve to a lead end, and a method which is carried out using this device
Inventor: ROESCH GEORG
IPC: H01R43/055
Filed: 1993-04-21
Abstract: In order to be able to fit a wire end sleeve in a fully automatically operating working cycle to a lead end (30) which has been stripped in advance, the wire end sleeves being intended to be taken from a magazine (34), the lead end (30) is pushed against a stop (37) which is advantageously at the same time an initiating device of an initiating sensor (35) for the working cycle. The completely inserted lead end (30) is initially fixed with the aid of a gripping device (41). The insulation of the lead end is then cut through at a predetermined point by means of a number of blades (55). Subsquently, the cut-off insulation end is pushed so far in the direction of the free lead end, by displacing the number of blades (55) with the cutting blades (56 and 57) closed, that the cut-off insulation end is entirely drawn downwards. The foremost wire end sleeve (93) in the magazine (34) is then pushed onto the free lead end, with the aid of a joining device. Finally, the wire end sleeve is permanently deformed with the aid of a crimping tool (55, 56), as a result of which it is permanently connected to the wire or to the braid of the cable. The other end of the wire end sleeve engages over the insulation. <IMAGE>

Title: Radiation disposal system for nuclear installations and other wastes and the disposal of complete installations, inter alia decommissioning
Inventor: MUNDT JUERGEN
IPC: F24J3/00
Filed: 1993-05-18
Abstract: In a room which is fitted with UV radiators and is placed under vacuum, the sources of radiation which are located in the room or on components or wastes are destroyed by the UV radiator; the energy content of the sources of radiation is emitted to the outer boundary of the room as heat; if necessary this must be cooled. Magnetic fields can also be arranged, which attract the voltage elements (nuclei) which are released. The temperature is thus reduced and can be controlled. In the case of steel containers and others where the sources of radiation or the materials must be enclosed, in accordance with regulations, cooling must be carried out in any case (cooling jacket or the like), the energy content of the exhaust heat can then be used in another way.

Patent DE-4328338-A1 (DE)
Title: Magnetic separator
Inventor: BARRMEYER CHRISTIAN DR
IPC: B03C1/18
Filed: 1993-08-24
Abstract: Magnetic separators are used for separating magnetizable components from bulk goods and are equipped with a preferably horizontal conveying belt (5) which is charged by a supply device and of which the discharge end is guided over a magnet roller (4) with alternately arranged permanently magnetic magnetic discs and intermediate discs. In the case of discs which are provided with a central bore and are retained by a shaft which passes through said bore and consists of a non-magnetic material, there are considerable disadvantages resulting from the magnetic losses caused by the construction of the magnetic roller (4). In order also to improve the capacity for separating, from the material which is to be cleaned, averagely and poorly magnetizable foreign substances, the magnetic discs and the intermediate discs are designed as solid discs and are bonded to a roller body at whose ends there is adhesively bonded in each case one roller-termination piece provided with a shaft journal. The entire roller volume is available for optimizing the magnetic action. Arranged above the conveying belt (5) is a comb-like directing device (7) with teeth (15) which are oriented in the running direction of the belt and pass into the bulk goods as far as into the vicinity of the conveying belt (5). <IMAGE>

Title: Implement for lifting manhole covers
Inventor: LEMKE KLAUS
IPC: B66F19/00
Filed: 1993-09-30
Abstract: The implement is especially suitable for lifting manhole covers in which the intermediate space between frame and cover is badly soiled or corroded. Owing to the fact that the implement puts the manhole cover under tension by means of the helical springs due to the tightening and thus produces a high tensile stress, a few hammer blows to the manhole cover are sufficient and it jumps out. I have already built and tested the implement and it functions perfectly. The advantage of the implement consists in the fact that:   1) one man can get the manhole cover out without effort, where otherwise two workers were required, and 2) work can be carried out in a substantially more cost-effective and time-saving manner.   <IMAGE>

Title: Method and device for placing connecting elements in crane tracks
Inventor: ELSAESSER RAINER
IPC: B66C7/08
Filed: 1994-04-16
Abstract: In the method of placing connecting elements in crane tracks, the connecting elements (threaded bolts) are fixed at their exact location before the crane track is poured and are integrally cast in the crane track. First of all only the threaded bolts are integrally cast in the crane track, since nowadays a non-shrink mortar is applied between the ribbed slab and the cast crane track. The non-shrink mortar serves as an elastic base. No separate formwork needs to be constructed in order to underpin the ribbed slab with the non-shrink mortar. No rework is required. Levelling is required only once. The device for carrying out the method can be mounted directly on the formwork, it is reusable.
