A liquid-cooled, four-valve cylinder head for a multi-cylinder internal-combustion engine comprises a casting having a cooling-fluid space between the cylinder-head bottom and a cylinder-head cover in which supporting struts are arranged for reinforcing the cylinder-head bottom, valve channels of gas-reversing valves and chambers for receiving secondary combustion spaces. Above the cooling-fluid space is located a control space with guide housings for receiving the cup tappets for the actuation of the gas-reversing valves. In order to obtain a cylinder-head construction which is structurally rigid and nevertheless can easily be produced, the chambers are cast together with the valve channels within the cooling-fluid space. Further, the supporting struts are equipped with ribs projecting into adjacent combustion-space portions, and the lateral outer walls of the cylinder-head housing are connected to one another in the region of the control space by transverse booms.

A sealing passage arrangement for a pipeline through a wall aperture in a housing of an internal combustion-engine is disclosed. The sealing passage arrangement is attached so as to be sealed by its housing edge delimiting the open side of the housing on a receiving surface and is constructed so that the disassembly of the housing can be done without previously stripping down the pipeline. A pipe connection is provided inside the housing before the housing is assembled, and an arrangement of the seal element in the wall aperture which can be effected simply, are provided. It is proposed for this purpose to construct the housing aperture extending from the housing edge into the housing wall, to provide in the latter a two-part seal element, to arrange one part of the latter upright on the receiving surface and to bring it into engagement with the other part retained in the edge aperture and to extend the pipeline between the two seal element parts.

The invention relates to a device for mounting two camshafts in the cylinder head of a multi-cylinder in-line internal combustion engine having especially four valves per cylinder, the device comprising bearing housings supported on the cylinder-head housing. To make it possible to provide a cylinder head with small valve angles and with more than four cylinder-head screws per cylinder, the bearing housings are accommodated in a camshaft bearing frame consisting of longitudinal and transverse webs and produced separately from the cylinder-head housing.

A detergent composition comprising three or more distinct regions, the composition comprising one or more anti-corrosion agents and a bleaching compound, wherein, the bleaching compound is predominantly located in a first distinct region, and the one or more anti-corrosion agents are predominantly located in a second distinct region having a pH in the range of from 5 to 8.9 which second distinct region is not in direct contact with the first distinct region, and further wherein the second distinct region has a lower pH than the first distinct region.

In an electromagnetic operating arrangement for actuating the intake and exhaust valves of an internal combustion engine wherein a valve operating member is movably supported in axial alignment with a valve stem and engaged by an operating member spring which biases the valve operating member into engagement with the valve stem, the valve operating member has an armature disc movably supported thereon but held in engagement with a stop on the valve operating member by a spring arrangement which exerts a spring force smaller than the spring force exerted by the valve operating member spring but greater than the resultant of the valve closing and the valve operating springs such that the valve operating member is always in force-transmitting contact with the valve.

A latch mechanism comprising a frame having an insertion axis therethrough. A first latch spring is disposed on the frame and is biased to an extended position. A handle is connected to the frame and is movable along the insertion axis between a first position and a second position. A first cam is disposed on the handle and moves the first latch spring to a retracted position as the handle moves toward the second position.

A memory package comprising a first cover portion connected to a second cover portion. The first cover portion supports a first electronics sub-assembly that comprise a circuit board with at least one memory module socket and at least one controller chip mounted thereto. The second cover portion supports a second electronics sub-assembly that comprises a circuit board with at least one memory module socket and at least one controller chip mounted thereto. The first and second cover portions are moveable between a closed position wherein the electronics sub-assemblies are nested and an open position wherein the electronics sub-assemblies are not nested.

A memory package comprising a first circuit board having a plurality of memory element sockets and a second circuit board coupled to the first circuit board and comprising a controller chip. The first and second circuit boards are disposed within a tray having a base and two sides. A handle is connected to the tray such that the handle is pivotal with respect to the tray. The handle has a lever system and latch that is slidably engaged with the lever system.
