Abstract: A method for controlling the opening of at least one intake valve of a combustion chamber in a periodically working piston engine, at least one intake valve of the combustion chamber being opened during a first partial period of a working period of the piston engine for charging the combustion chamber; and at least one intake valve of the combustion chamber being opened during a second partial period of the working period, wherein the second partial period begins after the combustion of the combustion chamber charge and has no overlap with the first partial period.

Abstract: An electrohydraulic valve control (10) of an internal combustion engine includes at least one actuator (24) that acts on a gas exchange valve (38). This actuator (24) in turn has at least one working chamber (30), which in order to switch the actuator (24) from a first position into a second position, is connected to a high-pressure hydraulic accumulator (16) and shut off from a low-pressure return (56). In order to switch the actuator (24) from the second position back into the first position, the working chamber (30) is connected to the low-pressure return (56) and shut off from the high-pressure hydraulic accumulator (16). The pressure in the high-pressure hydraulic accumulator (16) is kept constant or reduced in a simple manner by virtue of the working chamber (30) being connected to the high-pressure hydraulic accumulator (16) and the low-pressure return (56) at the same time.

Abstract: A connection between a shaft end of a gas exchange valve of an internal combustion engine and a final control element of a valve actuator, with at least two shell-shaped wedge-shaped pieces, surrounding the shaft end and braced on the final control element, whose radially outer circumferential surface extends conically and which are surrounded by at least one conical clamping sleeve whose radially inner circumferential surface extends complimentary to the cone angle of the wedge-shaped pieces, wherein on the radially inner circumferential surface of the wedge-shaped pieces and on the radially outer circumferential surface of the shaft end of the gas exchange valve, protrusions and recesses that mesh with one another are provided.

Abstract: The present invention relates to a connection (24) between a shaft end (20) of a gas exchange valve (1) of an internal combustion engine and a sleeve-shaped actuating element (2) of a valve actuator (4), which is guided in an axially movable manner within a pressure region (58), which is able to be pressurized with a pressure medium, of the valve actuator (4) and at least partially surrounds the shaft end (20).

Abstract: The invention relates to a connection (18) between a shaft end (14) of a gas exchange valve (1) of an internal combustion engine and a final control element (2) of a valve actuator (4), with at least two shell-shaped wedge-shaped pieces (22, 24), surrounding the shaft end (14) and braced on the final control element (2), whose radially outer circumferential surface extends conically and which are surrounded by at least one conical clamping sleeve (26) whose radially inner circumferential surface extends complimentary to the cone angle of the wedge-shaped pieces (22, 24), wherein on the radially inner circumferential surface (38) of the wedge-shaped pieces (22, 24) and on the radially outer circumferential surface (40) of the shaft end (14) of the gas exchange valve (1), protrusions (42) and recesses (44) that mesh with one another are provided.

Abstract: A method and apparatus for transporting loads includes a gripper pliers including a pair of pivotable gripper arms, each of which has a gripper claw. A positioning element is operatively coupled to the pair of gripper arms for pivoting the gripper arms in a pivoting plane and displacing the gripper arms in a gripping direction transversely of the pivoting plane into a position so that the gripper claws can engage connecting regions of the load. At least one of the gripper arms includes a transverse guide for fixing it against further pivoting and back-pivoting within the pivoting plane after the gripper arm has pivoted into an operating position for being displaced in the gripping direction.

Abstract: The invention relates to a transloading apparatus for transcontainers such as freight containers, interchangeable containers and semi-trailers including a crane trolley adapted to travel on a crane or portal, to which, by way of a lifting means, a load receiving means is fitted in a manner for raising and lowering.In order to enable the load receiving means to be guided and aligned more accurately in relation to the transcontainer, provision is made to connect to the load receiving apparatus two horizontally movable columns or lifting structures at a distance from one another which is fixed or can be adjusted in a defined manner and to render these vertically displaceable. Preferably each of the columns or each of the two lifting structures can be connected by way of a pendulum suspension to the load receiving means.

Abstract: A lifting and transport apparatus for containers has a fixed rigid horizontal beam on the lower flange of which two wheeled carriages are displaceable either together or separately to allow, in the latter case, a change in the distance between the carriages and, in the former case, displacement of the container. A cross beam on each of the carriages can carry at its ends fixed columns which guide respective lifting elements having claws at their ends engageable with the container. The entire assembly is free from cables or the like which can introduce sway.

Abstract: A light grid consists of a row (13) of adjacent light transmitters (11.sub.i) and adjacent light receivers (12.sub.i) arranged at a distance opposite to the latter. The light transmitters (11.sub.i) and the associated light receivers (12.sub.i) are individually activated cyclically one after the other. A determination is made at each light receiver (12.sub.i) whether a received light signal is present or not on activation of the associated light transmitter (11.sub.i). By considering, during the evaluation, the light receivers (12.sub.i-1, 12.sub.i+1) adjacent to the associated light receiver (12.sub.i) and the light transmitters (11.sub.i+1, 11.sub.i-1) adjacent to the associated light transmitter (11.sub.i), a differentiation is made between an obstacle introduced into the protective field (26) and a defect light transmitter (11.sub.i) and/or light receiver (12.sub.i).

Abstract: An acceleration switch has a seismic mass, which is suspended by springs (1) on a bearing block (7). The springs are designed as curved bending springs. If an acceleration acts on this sensor, then the seismic mass is noticeably deflected out of its neutral position when a critical acceleration is exceeded. By means of a lever (17), the seismic mass pulls a contact bar (21) toward a contact block (4), so that a current path is closed between the two parts of the contact block (4).
