Title: Light fitting control switch - uses variable resistor to gradually increase intensity over time interval to avoid dazzling user
Inventor: BREUER HANS DIPL PHYS DR
IPC: H05B37/02
Filed: 1976-09-17
Abstract: The light switch gradually increases light intensity from zero to the wanted level to avoid dazzling the user--i.e. to allow his eyes time to adjust to the new light level. The delay between zero intensity (or a min. intensity) and max. intensity may lie between 10 ms and 3s. The switch acts as an on/off switch with a gradual increase in current supply -- provided e.g. by a variable resistor. The slider must traverse the resistor before the 'on' contact of the switch is reached. A time counter may also be used.

Title: Permanent magnet excited AC generator - has constant voltage characteristic supported by periodic short circuiting of control winding
Inventor: VOLKRODT WOLFGANG DR ING
IPC: H02K29/00
Filed: 1976-12-30
Abstract: The permanent magnet poles are arranged to have a higher permeability in the quadrature axis than in the direct axis. This arrangement gives a machine whose voltage is substantially independent of load except at low lagging power factors. This deficiency is overcome by winding the machine multi-phase and by connecting capacitative compensation (6) across the output windings (1, 2), and by fitting a short circuiting device (7) across a control winding (3). In this way, a three-phase winding can be utilised to give a controlled single phase output. The closed time of the short circuiter depends on the magnitude and power factor of the load. A three-phase output can also be obtained by capacitor compensation across all phases, and by having a short circuiter across a number of turns in each phase.

Title: Label reader data correction - uses N-from-M tape code with constant band separation monitoring
Inventor: NAKANISHI SADAO
IPC: G06K5/00
Filed: 1978-04-06
Abstract: The method is for correcting the data read by a label reader which is used for label codes which cannot be read and for errors caused during reading to enable decoding of faulty bits as often as possible. The reliability and efficiency of the reader are thus improved. An 'n from m' label code is used to enable decoding of the information content of each bit read by the reader, which cannot be interrupted or which is invalid. The regularity of the code is combined with the information content of the other bits. A band code may be used with wide and narrow bands with constant separation. The separation is measured and invalid data evaluated from the deviation of the separation from the constant value.
