摘要:
The present invention relates to an apparatus for sealing tube plates of batteries, preferably lead-acid batteries, comprising a base body, on which projections are arranged, and when the apparatus is arranged in the intended manner, the projections engage at the end in the tubes of the tube plate.

The present invention relates to a device and a method for the detection of hydrogen in a gas volume by means of an exothermal catalytic recombination of hydrogen and oxygen present in the gas volume into water. The amount of energy that is released during such an exothermal catalytic recombination is measured in the form of a temperature difference and is compared with a stored limit value. When a corresponding limit value is exceeded an appropriate signal is output.

For an improved recombination system serving to catalytically recombine hydrogen and oxygen, which form in a storage battery, into water and incorporating an adapter union assembly for the gas-tight connection of the system to a storage battery, a container which is gas-impermeable to the outside and which houses a recombination assembly, as well as a conduit for the loss-less gas intake from the adapter union to the container and water return flow in the opposite direction, whereby even in the event of an overload the hazard of escaping gas can be avoided and the efficacy of the catalytic unit can be maintained while at the same time the system can be produced at low cost and in a way as to be easily assembled and maintenance-free, this invention proposes to provide next to the conduit an expansion section which is open toward the outside but delimited by an ignition suppressor, and to connect the conduit with the expansion section by way of a gating aperture.

摘要:
A chain guiding rail for use in power chain saws has a tip part defining an arcuate run-in section extending from an end point of a forward-run section to the vertex of the tip part, and a run-out section extending from the vertex point to a start point of a return-run section. The run-out section has a substantially larger diameter and a tangential line at its center point forms an angle (b8) of 40.degree. to 70.degree. with a center axis of the rail. To eliminate kickbacks during operation of the chain saw the vertex is situated in a sector of the tip part which is delimited by reference line coinciding with the center axis or extending in parallel thereto, a perpendicular line relative to the forward-run section at the end point (E) and to the parallel reference line or the center axis, and an arc whose center of curvature coincides with the point of intersection of the parallel reference line with the perpendicular line.
