Title: Eliminating interference in colour value signals of multichannel generator - adding HF signal of appropriate amplitude lying outside video signal band to each colour value signal
Inventor: VALK NIEK VAN DER DIPL ING
IPC: H04N9/73
Filed: 1991-12-17
Abstract: The method removes interference in colour signals of multi-channel colour picture signal generators which give rise to different signal to noise ratios. A h.f. signal of a given amplitude, lying outside the video signal band, is added to each of the colour signals. Each video signal output (1,2,3) of the opto-electric converter is connected to one input of an adder (7,8,9) via a normalising circuit (4). The h.f. signal of given amplitude is applied to the other inputs of the adders (7,8,9). The adder outputs are fed to a non-linear video signal processor (6). This provides interference-free colour signal outputs via a low-pass filter (16). USE/ADVANTAGE - For, eg. picture recorder of colour TV camera or film scanner. Change in colour of picture signal to be re-produced is prevented.

Title: Removal of nitrogen@ from turbine exhaust gases - by injection of reduction agent broken into transitional substances by exhaust heat energy before injection to catalytic converter
Inventor: OLDANI MARKUS DR
IPC: F01N3/28
Filed: 1992-01-11
Abstract: Catalytic removal of nitrogen from gas turbines (2) exhausts uses an agent to reduce the exhaust gas (1), following which the nitrogen is removed in a SCR-process catalytic converter (9). Reducing agent (6) is thermally split into transitional substances outside the exhaust catalytic converter, and the resulting products are then introduced into the main flow of exhaust gases (3) before they enter the catalytic converter. USE/ADVANTAGE - The process removes nitrogen from gas turbine exhausts. The process shortens the necessary exhaust gas residence time in the converter and achieves a higher efficiency of nitrogen removal. Further, the reactive agent is distributed more quickly in the exhaust gases, and thus has a shorter residence period and shorter exhaust passages. The arrangement achieves enhanced uniformity of distribution and more complete reactions with the NOx and thus enhanced efficiency.

Title: Knitting machine needle segments - has one-piece plastic constructions formed by injection moulding and suitable moulds
Inventor: GUTWALD VOLKER
IPC: D04B27/06
Filed: 1992-07-24
Abstract: The needles or platines are formed in a one piece segment by an injection moulding process. Pref. the mould is in top and bottom sections to form the base plate, and a further arrangement to form needles or platines which may have eyelets. The base is moulded in the cavity having plastic injected along passages. A projection leaves a hole in the plate. The platines are formed in the spaces between bars, which have a cross bore of increasing dimensions in the middle. A rod presses against the back of each bar as the cooled moulding is extracted. The container has a conical formation which allows the outer bars to release the moulded platine formed in the gaps from each end, and progressing to the middle, which ensures a clean release. The shape of the platine is reinforced at the base where is joins the plate, as this could be a weak spot. The bars have shapes for the platine and may have suitable moulded shapes to form an eyelet, therefore the separation of the bars is required to remove the mould from the eyelet. ADVANTAGE - The plastic formation is more economical and lighter than lead casting or steel welding, and therefore higher speeds are attainable.
