Abstract: A smoke detector containing a radiation source operating in a pulsed mode and a scattered radiation receiver connected in a coincidence circuit. This circuit contains a counter which counts both the radiation pulses and the incoming scattered radiation pulses. With undisturbed operation this counter, following each radiation pulse, has an even numbered counter state. The appearance of an uneven numbered counter state is indicative of the presence of spurious pulses and leads to resetting of the counter to null, so that there is prevented attainment of a counter state adequate for tripping an alarm signal. On the other hand, with the presence of a predetermined even numbered counter state there is triggered an alarm. Such smoke detector is almost immune to spurious pulses and does not tend to trigger faulty alarm signals.

Abstract: FILTRATION SYSTEM Abstract of the Disclosure A rotatable  disc  having  an  annularly  arranged screening  zone  includes  a  plurality  of  like  cavities separated by spacing webs.  A housing for the disc includes a first plate with a front and rear side and a second plate with a front and rear side.   The disc is rotatably mounted between the rear side of the first plate and the front side of the second plate,    A first flow-through bore in the first plate has a front side and a rear side and a second, aligned flow-through bore in the second plate also has a front side and a rear side,    The disc is mounted in the housing  such  that  at  least  one  of  the  cavities  is  in alignment with the first flow-through bore and the second flow-through bore,  the first flow-through bore, the second flow-through bore and the at least one cavity forming a flow-through channel,   The second flow-through bore has a pre-selected outer contour at the front side thereof,   The first flow-through bore includes a flow-shape forming means for causing the contour of a cross-section of the molten flow at the rear side of  the first flow-through bore to correspond with the pre-selected outer contour.

Abstract: A device for preventing resinous condensate dropping for use in a paint drying oven. The device includes a trough extending along an upper edge of a wall opening for passage of articles under drying treatment, to receive condensates of residual tar and guide them to laterally outwardly of the articles. The trough has a slate or other water-retentive member applied to an undersurface thereof to prevent formation of condensates on the undersurface. A glass wool member is interposed between the trough and slate to act as heat insulator.
