    摘要: A guide bar for a saw chain of a motor-driven chain saw has a guide groove formed in the periphery thereof. The drive links of the saw chain have projections known as rakers which protrude beyond the side links of the saw chain and which are guided in the guide groove. The guide bar has at least one supply bore in a groove wall through which lubricating oil is supplied for lubricating the saw chain. In the vicinity of the supply bore, a lubricant surface extending approximately parallel to the groove bottom is provided. This lubricant surface extends to at least one supply surface extending as far as the supply bore. The rakers of the drive links move above the lubricant surface with a narrow spacing. The lubricating oil supplied via the supply bore is guided via the supply surface to the lubricant surface where it forms a film into which the rakers extend as the saw chain revolves. This assures that the supplied lubricating oil is picked up by the rakers and carried by them to the link locations of the saw chain thereby assuring very effective lubrication.

    摘要: The invention relates to a connection of a crankcase (3) of an internal combustion engine (1) to a cylinder housing (2) of which at least one housing part is made of light metal. The housing parts (2, 3) lie with their respective housing flanges (4, 5) in surface contact one against the other and are clamped seal-tight to each other with the aid of retaining screws (7). The retaining screws (7) are of light metal and a curing liquid seal (18) is between the housing flanges (4, 5) so as to lie against both sides. In this way, a connection for a light metal cylinder housing (2) with a crankcase (3) is achieved by using light metal housing materials. A reliable seal is provided which is permanently resistant to the operating loads of the engine (1).

    摘要: A titration apparatus, which operated volumetrically and/or coulometrically, includes a basic apparatus with a control and actuation arrangement for the volumetric metering of reagents, a metering unit for the volumetric titration removably attached to the basic apparatus, and mechanical coupling elements for connecting the metering unit to the actuation device. Instead of the volumetric unit or in addition thereto, a coulometric titration cell may be connected with the basic apparatus directly or by an adapter unit, while using the same control device as the metering unit.

    摘要: A threaded closure is provided with a receiving opening 16 in the part thereof which projects into a fuel tank. The end of a limp connecting part 13 is rotatably mounted in this recess and is however axially fixed. The threaded closure prevents damage to the sealing surface and prevents the threaded closure from becoming separated from the fuel tank so that it cannot be lost.
