Title: multipurpose circuit for special lighting effect - is responsive to audio signals, esp. for theatres and concert halls and reacts to music, human speech or animal sound
Inventor: KOELCHENS GERT HEINZ MANFRED
IPC: H05B37/02
Filed: 1979-05-12
Abstract: The special lighting effect device is incorporated with a receiver with a multi-purpose circuit also allowing switching of other load circuits. The multi-purpose circuit has a number of evaluation logics for controlling associated switching elements and a further evaluation logic for the ON-OFF switching of the different operating modes. A volume measuring and limiting system supplies signals indicating the mean volume range. Volume limiting signals and start signals for initiating synchronisation intervals. These are obtained via a nionostable multi-vibrator and used for the operating of the controls, while a DC/AC voltage converter is used to supply an external viewing appts.

Title: Can cutting and trimming appts. - has several cutter unit cartridges each with axially fixed rotary knife transversely moving rotary knife and vacuum chuck holding can
Inventor: STROOBANTS ALPHONSE
IPC: B23D31/00
Filed: 1979-05-30
Abstract: The can end trimmer has a main rotary support shaft with a radial turret plate. Several self-contained cutter unit cartridge assemblies have radial head flanges connected to one side of the turret plate.

Title: Ultrasonic generator for dental treatment - has switched magnetostrictive transducer which maintains oscillator supplying switching pulses at transducer resonance frequency
Inventor: WIESER ALFRED
IPC: A61C17/20
Filed: 1979-07-21
Abstract: The magneto-strictive transducer of an ultrasonic generator is switched via an oscillator signal. A regulation voltage maintains the oscillator frequency at the resonance frequency of the magneto-strictive transducer. The regulation voltage is supplied from an integration stage (11,12) which is charged or discharged at the required switching rate and which uses the sum of a fixed voltage and the reaction voltage through a transducer winding (7) caused by the periodic switching. The oscillator comprises a multivibrator (1) supplying a signal via an RC element (3,4) to a switching transistor (6) with the transducer winding (7) connected in the collector circuit. The collector is connected via a diode (10) to an integration stage (11,12).

The spaces (11,12) facing the two ends of the adjustment piston are connected by lines (13,14) containing a control valve (15). The secondary piston is spring loaded (16) such that the spring tends to reduce the secondary combustion chamber's volume. The control valve is an electromagnetic valve that is open during the intake stroke and closed during the compression stroke when the secondary piston reaches a given position.
Patent DE-2937809-A1 (DE)
Title: Preventing condensate reaching sealed housing for motor - which drives rotary stirrer in pressure vessel
IPC: B01J3/04
Filed: 1979-09-19
Abstract: Rotary stirrer in a pressure vessel for heat treating materials etc. is driven by a motor housed in a sealed casing immediately adjacent the vessel and with a shaft passing through the vessel wall with a plain sealing ring. To equalise pressure, the sealed casing is connected to the pressure vessel by a conduit passing through the intermediate open space, and to prevent potentially harmful condensate from this conduit reaching the motor cavity, the conduit extends from the lowest point in the motor casing to an even lower point in the pressure vessel, and acts as a condensate return line. The conduit can be cooled to promote condensate formation. The pressure-balancing conduit permits use of a simpler seal than known devices with substantial pressure differences between vessel and motor casing, but consequently needs protection against clogging by the condensate inevitably formed in the conduit, which is cooler.

Title: Two stage turbocharger for diesel engine - uses high and low pressure turbines and compressors, cross connected for rapid response
Inventor: BHINDER FATEH-SINGH DR PHIL
IPC: F02B37/013
Filed: 1980-03-12
Abstract: The engine (1) has a two stage turbocharger which consists of two compressors (6,8) in series which are driven by two exhaust gas turbines (3,5) in series. Each turbine drives one of the compressors. The turbines and compressors are so arranged that the high pressure turbine (3) drives the low pressure compressor (6) and the low pressure turbine (5) drives the high pressure compressor (8). This combination enables the engine to respond more rapidly to load changes because an increased exhaust flow acts on the inlet side compressor first.
