Filed: 1990-06-13
Abstract: An electronic ballast for low-pressure discharge lamps supplied from DC or AC voltage networks, having an invertor (1) which supplies at least one lamp (8) via a capacitive reactance (6) connected in parallel with it and an inductive reactance (2) connected in series with it, an electronic harmonic filter (4) with a step-up inductor (L3) and a digital control circuit (2) for the invertor, which control circuit is connected to a DC voltage supply circuit (3). The DC voltage supply circuit is connected to the harmonic filter and has a capacitor (C3) which can be charged to the supply voltage of the control circuit via a first transistor (T4). The first transistor switches on immediately after the supply voltage of the electronic ballast has switched on. A blocking circuit (R6, R7, C4, T5) switches the first transistor off once the capacitor is charged and the latter is continuously recharged via an additional auxiliary winding (N1) of the step-up inductor and a rectifier circuit (D1-D4) connected thereto. In consequence, the voltage required to supply the control circuit is made available immediately after the start, in the case of both DC and AC voltage operation. <IMAGE>

Patent DE-4127120-A1 (DE)
Inventor: SCHUETZE HERBERT DIPL ING
IPC: H04N5/08
Filed: 1991-08-16
Abstract: In digital processing, in particular, it is often necessary to extract a synchronisation signal from a composite image, e.g. an FBAS, studio standard or TTL signal, in order, for instance, to synchronise a PLL (Phase-Locked Loop) therewith. Prior art processes, however, operate inaccurately in the vertical blanking gap of the FBAS signal or generate errors in the case of high-level burst signals. Initially a first reference voltage is formed which is obtained from the blanking level of the image signal (103). From this first reference voltage is formed a second reference voltage (105) with its d.c. voltage level lying roughly at the centre between the blanking level and the synchro-base. From the synchronisation pulse are obtained scanning pulses (109) which are used to generate a third, more accurate reference voltage (115). Shortened scanning pulses (111) are formed from these pulses which start after the beginning of the scanning pulse and stop before its end. These shortened scanning pulses and a sample and hold function (112) are used to measure a value representing the voltage of the image signal synchro-base, to which a further set offset voltage is added. This provides the third, more accurate, reference voltage (115), the level of which lies about midway between the blanking level and the synchro-base. This third reference voltage now exactly follows the level of the synchro-base with changing synchronisation pulses, e.g. in the vertical blanking gap. From the third reference voltage (115) are then obtained accurate synchronisation signals (117) which exhibit very little jitter and are insensitive to over-raised burst signals and permit the generation of exactly timed beat pulses even inside the vertical blanking gap.

Title: Optical to electrical signal conversion - feeding electrical signals into analogue shift register at specified clock frequency
Inventor: KNUPFER KLAUS DR
IPC: G01S7/487
Filed: 1991-10-19
Abstract: The method involves converting optical signals (1) with a period of first frequency into electric signals, which are fed into an analogue shift register (7) with a clock frequency that is an integral multiple of the first frequency. After the latter period, the contents of the shift register are transferred in parallel into a cache register (5). The process is repeated over a preset number of the first frequency periods for accumulation of a time resolved charge pattern in the cache register. After a preset number of periods, the signals are transmitted sequentially to a connected circuit (6) for amplification. USE/ADVANTAGE - For optoelectronic time delay range finding with weak HF optical signals. High noise suppression.

Title: Textile sample removal from an autoclave - has a probe with connection to carry sample and liquid through to a vessel when valve is opened
Inventor: JASPER JOSEF
IPC: D06P1/94
Filed: 1992-03-05
Abstract: To extract samples from a pressurised autoclave, used in the treatment of textile substrates a probe is directed at least at one sample, and is positioned with a connection between the autoclave and a vessel. On opening a valve, the sample is carried through the probe with the liquid flowing through it. Pref. the cylindrical probe is attached to the sample, and an overcritical fluid is used at a pressure of 30-600 bar and especially 200-400 bar. The fluid in the vessel is passed to the autoclave reservoir. Before the valve is opened, the fluid in the vessel is at a lower pressure than the fluid pressure in the autoclave. USE/ADVANTAGE - The method is for the extraction of sample from a pressurised autoclave, to monitor the processing operation, such as in the treatment of textile substrates during dyeing, sizing, boiling, kier boiling, bleaching and the like. The operation gives a trouble-free extraction of a sample to check the processing action, with safety.
