Title: Process for the minimisation of the quantity of external air and for energy saving in the swimming bath region or similarly for other regions
Inventor: SCHILLING HEINZ
IPC: F24F5/00
Filed: 1983-07-13
Abstract: The quantities of external air for the individual swimming bath regions were hitherto established by the criteria present in each case in these regions, e.g. according to the number of persons or according to the maximum permissible room humidity or maximum evaporation. The idea according to the invention now relates to a process of multiple use of the external air/supplied air, insofar as the minimum requirements for fresh air per person and for maximum room humidity are not exceeded, and insofar as heating energy is to be used. Thus the exhaust air from the entrance region or even the changing region can still be used for dehumidifying the swimming hall. Also the exhaust air of the swimming hall is still well suited for ventilating the shower rooms. This takes place according to the invention in that the individual regions of the partial or entire external air-supplied air quantity are caused to flow successively through the sequence: entrance, changing region, swimming hall, and shower region.

Patent DE-3337979-A1 (DE)
Title: Measurement method for evaluating chain wear
Inventor: ENGELHARDT KURT
IPC: F02B77/08
Filed: 1983-10-19
Abstract: A measurement method for evaluating the local bushing wear of chains, which is manifested by a lengthening of the chain pitch of the chain links. The lengthening of the chain pitch is also accompanied by an increase in the contact radii, with respect to the axis of the sprocket wheel, of the chain links which positively engage in the teeth edges of the sprocket wheel. The radial distances from the axis of the sprocket wheel or from a reference radius at a circumferential point in the arc section of the chain which is in contact with the sprocket wheel are therefore measured and compared with a chain-drive-specific limit value which has been determined empirically in advance and which should be the maximum permissible. If the distance values are larger than the permissible limit value, a local state of wear is, for example, present in the chain which will be responsible for damage.

Title: Monostable operating magnet
Inventor: HARTING DIETMAR DIPL KFM
IPC: H01F7/14
Filed: 1984-06-26
Abstract: For a monostable operating magnet, whose armature is held in the initial stroke position by the action of permanent-magnetic force, and it being possible to move the armature by the action of electromagnetic force into the final stroke position, it is provided for an axially magnetised permanent magnet to be arranged on the armature, it being possible for the permanent magnet to move axially - with respect to the core axis - between a core pole which can be magnetised electrically and a pole piece (limb) which is arranged at a distance therefrom. In this case, an opening is provided in the pole piece, into which opening the permanent magnet moves while maintaining a radial air gap in the final stroke position. The radial air gap is in this case dimensioned to be so large that, once the electrical excitation has been disconnected, the action of the permanent-magnet force between the permanent magnet and the core is greater than the action of the force between the permanent magnet and the pole piece, so that the permanent magnet and the armature connected thereto are moved back into the initial stroke position, close to the core.
