Title: Simultaneous supervisory and clock recording of several persons - checks clock time, common time presence and misuse
Inventor: TONNE FRIEDRICH DIPL-ING
IPC: G07C1/12
Filed: 1973-08-29
Abstract: The equipment described has two forms. The first is an automatic clocking device for work personnel which starts counting 'time at work' for each member when a personal security key is inserted. To cater for 'flexitime', insertion of the key is blocked and a lamp illuminated at the beginning of common time (when all personnel must be present). Late comers must then get the assistance of a supervisor to be able to insert their key. To reduce mis-use by leaving keys inserted a supervisory timer (e.g. 24 hrs.) checks the presence of keys and disconnects the time counter connected by any key still in place. Reconnection requires the assistance of the supervisor. The second form uses electronic control with punched cards for clocking in personnel.

Title: Coiled stock for making helical springs - is cut to length after heating to eliminate plastic deformation affecting tolerances
Inventor: LINDEMANN WOLFGANG DR ING
IPC: B21F3/00
Filed: 1975-01-29
Abstract: The helical or spiral springs are made from cylindrical or tapering spring steel wire processed from coil by straightening, stripping, cutting to length, heating and winding. The wire lengths are no longer straightened after stripping and before winding and the length tolerances are hence accurately maintained since no plastic deformation takes place. The wire stock is heated immediately after stripping, and cutting to length is carried out after heating of the wire stock. The plant performance is three to six hundred springs per hour for wire lengths from three to four metres for spring diameters from ten to twenty millimetres. Space occupied by the plant is twenty five metres long and four metres wide.
