Abstract: 512,757. Kitchen ranges; hot-water boilers. EBE-VERKEN AKTIEBOLAG. Nov. 8, 1937, No. 30618. Void. Convention date, Aug. 13. [Class 126] [Also in Group XIII] A cooking-range comprises two combustion chambers 1, 7 with grates 14, 15. The front, back, and side walls 9, 11, 12 of the chamber 7, together with a partition 10. deflning a flue 13, are hollow and form a water-boiler. The chamber 1 has three outlets, an outlet 6 leading to the chamber 7, and outlets 4, 5 which lie beneath hot-plates 2, 3 and lead when open to a flue above superposed ovens 37, 38 and below further hot-plates. A damper 8 can be moved to a number of positions, e.g., to close the opening 5 entirely while leaving the outlet 6 open, or to close the outlet 6 while leaving the outlet 5 open to one of the two chambers 1, 7. The hot-plates 2, 3 can be raised, as shown, or lowered to prevent passage of hot gases to the oven flue. Hot gases which pass through 'the latter enter a smoke chamber behind the ovens 37, 38 and beside the combustion chamber 7. The smoke chamber contains an auxiliary boiler 29 connected to the .main boiler. The hot gases from the flue 13 also enter the smoke chamber through a top opening controlled by a damper 31. A curved screen 32 which can be raised and lowered, and situated in the upper part of the smoke chamber determines whether the hot gases from both flues pass to the outlet 28 directly or around the auxiliary boiler 29. The oven flues have a damper 39 and outlets 41, 42 to the smoke chamber. The grate 15 obtains air through a duct 18. The draught regulator 20 of the opening 19 to the ashpit of the grate 14 is linked to a damper 20', so that the duct 18 is closed at the same time as the opening 19. An ash-box 17 forms part of the duct 18, and an ash-box 16 rests on bars 21. It is also stated that either of the boilers may be dispensed with.

Abstract: 1431799 Colour television EASTMAN KODAK CO 2 July 1973 [3 July 1972] 31427/73 Heading H4F A received colour television signal is recorded, using a flying-spot scanner 12, on a photographic colour film 36 using a colour strip filter 60, or on a black-and-white film incorporating the strip filter 60, the colour of the light transmitted by the filter at any instant being detected so that the correct one of three gates 70a- 70c is gated on to pass to the grid 32 of the flying spot scanner 12 the colour difference signal, separated from the received colour television signal, corresponding to the colour of the detected light, the separated luminance signal being fed to the cathode 16 of the scanner 12. For a filter 60 having red, blue and green filter strips the colour of the light passed by the filter 60 is detected using three photo-detectors 52a-52c and associated difference amplifiers 84, 86, 88 and AND gates 90a-90c, each of which gates produces an output for only one of the colours blue, red, green. The strips of filter 60 may be at right-angles to or parallel to the line scanning direction of scanner 12. Filter 60 may include transparent strips. For a black-and-white film a negative exposure may be carried out by inverting the colour difference signals and luminance signal. Signals may be derived from a previously recorded film by switching switches 26a-26f and 56a-56c to their dotted line positions. The position of the raster of scanner 12 is controlled to follow the movement of the film 36 by a circuit 20 receiving television field sync. signals and signals from a perforation sensor 40, circuit 20 being as described in Specification 1,361,457. A circuit 74, which is the same as that described in Specification 1,431,800, ensures that each film frame is exposed to the same number of television fields.

Abstract: 1,216,946. Capacitors. SIEMENS A.G. 23 June, 1969 [24 June, 1968], No. 31555/69. Heading H1M. In a method of making capacitors by dividing up parent capacitors, the laminated dielectric and electrode strips forming a plurality of parent capacitors are stacked, or coiled on a drum with the parent capacitors separated from each other by a capacitively inactive layer, and the assembly is divided up perpendicular to and along the latter layer. As shown, the inactive layer comprises metal layer 2<SP>1</SP> extending beyond the end of the capacitor foils and plastics foils 2 which do not. The capacitor foils and inactive layers are coiled on drum 3 and contact layers 4 are applied, e.g. by Schoop coating prior to division. Individual capacitors are obtained by making radial cuts and peeling away from metal layer 2<SP>1</SP>. The inactive layer may comprise only the metal layer (Fig. 1, not shown) or only the plastics layers (Fig. 2, not shown). In the latter case a cut is made through the inactive layers perpendicular to the radial cuts, and the end regions of the inactive layers where the cut is to be made may be left free of contact layer, by masking or by local removal. The inactive layers may constitute covering layers of the eventual capacitor (Fig. 5, not shown). The assembly may be consolidated by heat and pressure, e.g. by relaxation of heat-shrinkable plastics foils forming the inactive layers and solvents or adhesives may be introduced between the dielectric foils. The covering foils may be cast plastics foils which may contain 0À25% residual solvent. The dielectric may be polycarbonate or polyethylene terephthalate on which electrode material is coated.
