In the making of a lead storage battery, it is proposed to store all the sulphuric acid necessary to establish the final acid density of a working electrolyte as lead sulphate in the active mass of the plates and then to pour a water gel-forming mixture into the cell compartments.

A line pressure (PL) is adjusted based on data which are updated after evaluation of an intertia phase time of a previous shifting in comparison with a predetermined value. Thus, during the next shifting of the same kind, a shifting friction device is engaged by the line pressure (PL) which has been properly adjusted, thus assuring shock-free shifting irrespectively of manufacturing variations and...

The invention relates to a method for determining the spatial content of spaces, especially subterranean spaces, such as for example cavities, caverns, caves and the like. The essence of the invention resides in the fact that the volume of a medium filling the space being studied is changed by a sudden and short-lived increase or decrease in volume. In this arrangement, the pressure prevailing in ...

Transport and conveying apparatus for prawns comprises conveying equipment (1) for prawns and a feeler device (8) with a feeler element (10) which is pivotably mounted to rotate about an axis (12) parallel to the path of the prawns and which is cyclically lowered onto the prawns before conveying on for processing. That part of the feeler element (10) which comes into contact with each prawn is in ...

An "Automatic Exit Delay" circuit of a burglar alarm is placed on Stand-By whenever a "first" door is opened and the burglar alarm automatically starts to work right after the "last" door is closed. At that moment of arming a "Quiet Quick Test" Network automatically tests the alarm for proper functioning and generates a short "beep" to indicate such as well as the armed state of the alarm system.
