Title: Vertical deflection circuit for a cathode ray picture tube with pin-cushion distortion correction circiut
IPC: H04N3/233
Filed: 1977-02-11
Abstract: To correct pincushion distortions of the picture in the vertical direction on the screen of a colour television picture tube, the vertical output amplifier is supplied with a correction signal (3) in addition to the frame signal (2). This correction signal consists of line-frequency squarewave pulses which are sawtooth-modulated at frame rate in amplitude and phase. The output of the vertical output amplifier (1) is connected to a series resonant circuit (4, 5), the capacitor (5) being connected to earth and the vertical deflection coil (6) being connected to this capacitor (5). The output impedance of the vertical output amplifier (1) is reduced for line frequency by voltage feedback (10, 11). These measures simplify the construction of the correction circuit. Neither a transductor nor a transformer or an additional amplifier are needed for injecting the correction signal. <IMAGE>

Filed: 1923-03-01
Abstract: 216,922. Lamplough, F. March 1, 1923. Rectifiers.-Vapours obtained in the cracking of oils or the distillation of oil-bearing materials. such as shale, are gradually cooled and the uncondensed vapours are intimately mixed with the condensates obtained at each stage of the cooling. By this means, the yield of saturated liquid hydrocarbons is increased, and the yield of unsaturated hydrocarbons and free hydrogen is diminished. The vapours at a temperature of about 400-430‹ C. enter through an opening 5 the lower chamber 6 of a tower 7 which contains superposed bells 8 having perforated side walls and closed conical tops. The bells rest upon gutters 9 shaped so as to cause the condensates to flow over the interior wall of the tower. The vapours pass through the perforations and impinge against the descending condensate. They are directed by the gutters to the inner part of the bell above. The chamber 6 may contain a coil through which the hot vapours pass to vaporize light oils from the condensate. A series of towers may be used to cool the vapours to 150-200‹ C. The uncondensed vapours pass from the top through a pipe 16 to a scrubbing condenser through which they pass downwards. The condenser is in the form of a tower having a cooler at the top and below it a series of perforated bells, the gutters between which are formed so as to direct the condensate on to the top of the bell below. The uncondensed gases are withdrawn from the condenser by a pipe which projects upwards into a second pipe depending from the inside of the bottom bell.

Abstract: 1,062,395. Reactors. BABCOCK & WILCOX Ltd. Feb. 11, 1966 [Feb. 19, 1965], No. 6068/66. Heading G6C. In a marine pressurized water reactor, the core is surrounded by water contained within a safety tank which acts not only as a shield but also serves to condense any steam that should escape from the primary coolant system in the event of an accident such as a burst occurring in the system. The primary coolant has only short-life radioactivity so that contamination of the safety tank is not a serious problem but should damage occur in the reactor, by the failure of a fuel element, for instance, excessive contamination may result and additional shielding is provided for in such circumstances by a containing wall around the safety tank, the annular space between which is flooded with water by pump means in an emergency. The containing wall may be formed from locking hinged bulkheads which can be quickly swung into, and secured in, positions in which they form the wall. In this way it is not necessary for the ship to carry continually a sufficient bulk of water to provide a shield that will be effective against all eventualities.

Abstract: 1,070,868. Moulding chocolate or like pourable compounds. INRUPA A.G. Feb. 16, 1965 [Feb. 18, 1964], No. 6549/65. Heading B5A. [Also in Division B8] A device for charging pourable compounds, e.g. chocolate, into mould cavities embossed in foil strips which form at least part of the wrapping for the moulded compound comprises a moving main conveyer having members which engage the embossed foil from below between the embossed cavities therein to convey it below pouring nozzles, a cutting device upstream of the nozzles for cutting the foil into sections, each section containing a complete number of cavities, and an intermediate conveyer or slide between the cutting device and the main conveyer. Foil strips (2) arranged side-by-side are conveyed through an embossing device (1) to form mould cavities. A conveying rake (3) rotates rectilinearly so that on each stroke a finger engages the embossed strip in the space between cavities and carries the strip forwards a distance (t) and between cutters (5) on to an endless conveyer (7). In Figs. 9 and 10 (not shown) each stroke of the member (3) causes the strip to move forwards a distance t + r thus allowing a return movement of length r for the strip during the subsequent embossing stroke which avoids splitting of the foil. The cutters operate when a predetermined length of foil strip has passed therethrough. From the conveyer (7) the section passes on to a main conveyer (9) which comprises a pair of endless chains (11) and a moving endless conveyer (23 for supporting the foil between the chains. Ledges (15) extend across the chains and at the transfer point between the intermediate conveyer and the main conveyer a ledge engages between the leading cavities of a foil section to carry it on to the main conveyer to pass under pouring nozzles (27). Each foil strip may be engaged by two ledges, one at the front and one at the back, the one at the back being adjustable to allow for cavities of varying size (Fig. 8, not shown). An extra conveying movement finally brings the sections into close proximity.
