Title: Automatic repeater for selected tape record sections - uses ROM for start and end points of section control detector of tape travel
Inventor: FREY ERNST
IPC: G11B27/11
Filed: 1977-03-16
Abstract: The automatic repetition device is for information recorded on a tape machine, in which memory units acting as a r.o.m. (34) serve to store one or more start and finish points for sections of the recording to be repeated during a repetition cycle. Transducers (30, 32, 33) can be coupled to one of the spool shafts to derive a signal representing the path traversed by the axis to identify the parts of the tape to be repeated. In conjunction with the memory units they make possible the automatic repeated repetition of selected parts of the tape.

Patent DE-2721253-A1 (DE)
Inventor: KREUTZER OTTO
IPC: H05B41/282
Filed: 1977-05-11
Abstract: In the case of operating circuits, which have no starter and operate with a high-reactance transformer (3) and an invertor (2), for fluorescent lamps (5) cold starts frequently occur particularly at relatively high environmental temperatures, which cold starts greatly reduce the life of the fluorescent lamps if they occur frequently. In order to prevent this, the starting voltage is switched on delayed with respect to the heating voltage for the incandescent cathodes (51, 52), for example by means of a triac (62). <IMAGE>

Patent DE-2818218-A1 (DE)
Title: Supercharged internal combustion engine - has steam driven injector as supercharger with steam raised by engine waste heat
Inventor: MUELLER FRANZ
IPC: F02B29/02
Filed: 1978-04-26
Abstract: The exhaust gases of the engine pass through a waste heat boiler in which they evaporate water to medium or high pressure steam. The steam is taken to an injector in which it draws in the air or fuel air mixture and raises it to a high pressure. This stream then also contains steam which enters the cylinders with the mixture. The injector supercharges the engine and thus increases the efficiency and the output from a given size engine. The addition of steam into the mixture also improves combustion efficiency and thus reduces the concentration of pollutants in the exhaust.

Thickness detector output signals are fed to a peak detector driving a subtractor and a measurement range switch. A reference voltage is connected to the other switch input and the switch output drives the other subtractor input. The subtractor and range switch drive a sensitivity correction circuit. The thickness proportional signal is produced by a summer adding the range switch output and the correction circuit output.
