Title: Improvements in or relating to steam power plants
IPC: H04L25/49
Filed: 1966-03-01
Abstract: 1,098,116. Preheating air for combustion; feed water heating. BABCOCK & WILCOX Ltd. March 1, 1966 [March 1, 1965], No. 9039/66. Headings F4A and F4B. [Also in Division F1] During normal operation of a steam turbine plant, combustion air supplied by a fan 8 to a boiler 1 is preheated in a heater 4 by steam bled from a turbine 3 while part of the feed water from a condenser 13 is preheated in a heater 5 by further steam bled from the turbine, the remainder of the feedwater being preheated in a flue gas cooler 12. At peak load, valves RA, RE are closed and valves RD, RC are opened, and the combustion air is then heated by an auxiliary combustion chamber 6. Since steam is no longer being bled from the turbine 3 to supply the heater 4, the turbine develops extra power to meet the peak load. The valves RA, RE, RD, RC can be set to intermediate positions at loads between normal and peak. At superpeak load a further increase of turbine power is provided by operating a valve 20 to reduce or stop the bleed of steam to the feedwater heater 5, the feedwater being correspondingly diverted to the flue gas cooler 12 and the heat input to the latter being correspondingly augmented by means of an auxiliary combustion chamber 7 fed by a fan 11. The combustion chambers, 6, 7 operate on liquid or gaseous fuel. A duct 9 with a valve RB enables the heater 4 and combustion chamber 6 to be connected in series. When the boiler 1 is being started up, it can be preheated by the combustion chamber 6. In a modification, the flue gas cooler 12 is supplied with feedwater from a point within the heater 5 so that part of the heater 5 is in series with it and the remainder is in parallel with it.

Filed: 1973-02-24
Abstract: 1406130 Collating sheets GEORGE HARTLEY & SONS Ltd 9 Nov 1973 [24 Feb 1973] 9189/73 Heading B8R Sheets are separated from the top of piles in trays 3, Fig. 1, on a table 1, and fed on to corresponding support structures above receiving locations 4 on a table 2. Each support structure comprises three metal plates 7, Figs. 1 and 2, turned up at one end 8 and there fixed to a bar 9, and extending over the location 4 so that their free ends 10 are spaced from the table 2 but lower than the end 8, an adjustable rear stop member 11, and a fixed front stop member (not shown). In operation, one sheet is separated from each pile and carried over the member 12 and on to the plates 7 over each location 4. As the feed means returns to separate the next sheet, fingers 6 mounted on endless chains and projecting upwardly through slots 5 in the table 2 move o the lift and convey the sheet on the plates 7 together with any sheets on the table 2 below the plates 7 into a position below the plates 7 at the next location 4. This process is repeated, and thus each location 4 becomes a receiver for a stack of sheets, each stack comprising one sheet from the corresponding pile and one sheet from each of the piles to the right thereof. As each stack reaches the leftmost location 4, it will comprise one sheet from every pile.

Title: Processing of sheets of printed security papers into bundles and packets
IPC: B07C3/08
Filed: 1975-03-06
Abstract: 1483956 Conveying bank notes DE LA RUE GIORI SA 6 March 1975 [26 March 1974] 9271/75 Heading B8A In a process for conveying and collating bank notes in bundles, those bundles which contain imperfect notes are withdrawn at one position in the process and are replaced by dummy bundles. At a later stage the imperfect bundles (having been rectified) are replaced in their original position in the stream, in place of the dummy bundle, so as to avoid errors occuring in the serial number of the notes in each series of bundles. Sheets 1 on which 24 notes are impressed in four columns and six rows, are supplied in successive stacks of 100 sheets to the input A of a cutting machine having four stations C1-C4 after which the stacks are transformed into bundles 3 of one hundred individual notes. At a station G, each bundle is subject to a detector which causes any bundle comprising an imperfect note, to be diverted to a conveyer 95. In each space left by a diverted bundle is inserted a dummy bundle at a station K. Each diverted bundle is reformed at a station S and fed on to a conveyer 97. The main stream of bundles is fed by a conveyer 91 into compartments of one or other of two rotary conveyers M1, M2. Each conveyer M1, M2 comprises 24 radially disposed compartments. Each of the latter receives ten bundles. While conveyer M1 is being filled with bundles, M2 is being discharged (on to a respective branch of a conveyer 92), and viceversa. At stations N1, N2 operators replace the dummy bundles with reformed bundles from the conveyer 97. The packets of ten bundles are then banded at station O. The band is printed at station P. The packets are successively tumbled on to their sides and subject to wrapping at station Q, from whence they are collected in lateral rows on a conveyer belt 94. The rotary conveyers M.-The twenty-four magazines are defined by pillars 30 and radially extending members 31. The base of each magazine is formed by a member 42. The twenty-four members 42 are carried by a ring 43 that is in threaded engagement with three rods 35. The latter carry respective sprockets 39 which are connected by a driving chain to a sprocket 41. The latter is normally stationary. Thus when the magazines rotate and successively receive bundles from the conveyer 91, the members 42 (which start in the upper (broken line) position in Fig. 5), are lowered by the thickness of one bundle for each complete rotation of the conveyer. When each magazine is filled with 10 bundles the packets so formed are discharged from the magazines by a pusher 50.

Abstract: <PICT:0829908/IV (a)/1> A sliver 19 comprising a mixture of non-adhesive and potentially adhesive fibres is drawn by rolls R through a die 20, a heated chamber 18 where the potentially adhesive fibres are rendered tacky by a separately introduced solvent, and a smaller die 23 producing a compressed filter body, which may be of such size and shape as to form the absorbent element in dental and surgical pads, dressings or tampons but which, as shown, is a rod 31 in which the tacky fibres have set and around which a paper web 55 is wrapped by a former 50 and gumming means 60, lengths cut from the wrapped rod 31 being used within the wrappers of cigarettes as filter plugs.  The non-adhesive fibres are of regenerated cellulose such as mechanically or chemically crimped fibres of rayon staple and preferably comprise 75 to 90% by weight of the sliver, the rest of which is comprised by the potentially adhesive fibres, which may be crimped and are vinyl resins such as polyvinylchloride or copolymers of vinyl chloride and vinyl acetate or of acrylonitrile and vinyl chloride.  Both non-adhesive and potentially adhesive fibres are at least 9 microns in diameter (preferably 1 to 1 1/2 denier) and may vary in length from 5/8 inch to 2 1/2 inches, many of the shorter fibres being disposed transversely of the rod 31.  As described, the potentially adhesive fibres are rendered tacky by introducing as a solvent liquid acetone, directly on the sliver 19 or on to the chamber wall for vaporization, the chamber 18 being heated to about 110 DEG  C. by one or more heaters 25.  Setting of the rod 31 occurs outside the die 23 or partially therein.  The diameter of the former 50 is less than that of the die 23, to reduce the rod diameter further.  To eliminate fouling of the dies 20, 23 they are of polytetrafluoroethylene and the die 20 has a p  bevelled rear edge. The chamber 18 may be vented via flats on the outside of the die 20. The fibres may be coloured, dyes being incorporated with the spinning solution or by bath dyeing the spun filaments from which the staple is cut.  Essential oils, and aromatics such as perfume and menthol, may be incorporated.  The rayon fibres of the completed filter swell as they become moistened during use.  The Registered Trade Mark "Vinyon" is mentioned.

Filed: 1957-03-22
Abstract: 807,391. Carrier transmission. STANDARD TELEPHONES & CABLES Ltd. March 22, 1957 [March 28, 1956], No. 9513/57. Class 40 (4). In a single-channel carrier telephone system of the kind having one main station which feeds carrier to the line and one, or more, passive secondary stations, the (or each) passive station employs a dynamic microphone and includes a transistor microphone amplifier the power for which is provided by rectified carrier from the modulator-demodulator. As shown, carrier current incoming from the main station (not shown) is applied via a phase corrector FC to the modulator/demodulator MD, the direct current output of which produces a unidirectional voltage which is applied across the capacitor C to provide the supply voltage for the transistor TR. When the operator at the passive station speaks into his electrodynamic microphone the output therefrom is amplified by the transistor amplifier having a gain of about 20-25 db., and is applied via the low-pass filter FL1 to the modulator. The modulation products pass to line via the usual band-pass filter (not shown). Incoming currents from the main station, which consist of sidebands and carrier, are demodulated in MD, and the voice-frequency demodulation products pass via the low-pass filter FL1 to the receiver T.

Title: Improvements in or relating to the manufacture of sodium hydroxide and ammonia
IPC: C01D1/26
Filed: 1930-03-26
Abstract: In a modified ammonia-soda process, sodium bicarbonate obtained in the usual manner is converted into sodium cyanide by the known reaction with carbon and nitrogen and hydrolyzed in known manner with steam to produce caustic soda and ammonia.  Solid sodium bicarbonate, made by precipitation with carbon dioxide from ammoniacal sodium chloride solution, is mixed with carbon such as coke, and treated with nitrogen at a temperature of e.g. 1000 DEG  C. The cyanide is removed and treated with steam at e.g. 400-500 DEG  C. The ammonia produced may be introduced into the process; thus it may be used to saturate the ammonium chloride liquor, sodium chloride being added to saturation and sufficient carbon dioxide to give a complete conversion to ammonium carbonate, the solution on cooling to about 5 DEG  C. precipitating ammonium chloride which is removed by filtration, the filtrate being used for further precipitation of bicarbonate.  Carbon dioxide produced during the heating of the sodium bicarbonate may be used for the precipitation.
