Title: Process and means for reducing loss of head effects in the channels of a liquid cooled nuclear reactor
Inventor: ANGELINI ANTONIO
IPC: B30B1/10
Filed: 1964-04-10
Abstract: 1,047,179. Cooling reactors. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). April 10, 1964 [April 11, 1963], No. 14971/64. Heading G6C. In an organic liquid cooled, heavy water moderated, nuclear reactor, the coolant passes down each pressure tube over the fuel elements and leaves through a Venturi type nozzle; a reduction of coolant pressure is produced at the outlet proportional to the flow rate and this maintains the pressure at the outlets of all the pressure tubes at the same value so maintaining the free level of the coolant at a selected value. Thermal insulation between the pressure tubes and the associated colardria channels is effected by a gas atmosphere. Coolant penetrates partially into the gas space and the gas rests above the free surface. The atmospheres in all the channels are connected to a common external gas reservoir.

Title: Improvements in methods of and apparatus for cracking and distilling oils
Filed: 1925-06-09
Abstract: 235,564. Motor Fuel Corporation, (Assignees of Richey, C. F., and Duffee, P. Y.). June 16, 1924, [Convention date]. Hydrocarbons, cracking.-Heavy hydrocarbon oils such as fuel oil or kerosene distillate are treated to obtain light oils by heating them to a cracking temperature under sufficient pressure to maintain the liquid phase, cooling to about normal temperature while still under pressure, releasing the pressure, to allow escape of permanent gases and distilling the resultant oil by heat exchange with the heated oil. The oil is forced by a pump 80 through heat exchangers 21, 5 and through furnace-heated tubes 2 in which it attains a temperature of 850-950‹ F. under a pressure of about 600 lbs. The heated oil is cooled by passage through the heat exchanger 5, coils in the still 12-12<b>, the heat exchanger 21 and a coil 23 immersed in cold water. The cooled oil flows through a pressure-reducing valve 30 into a chamber 31 divided by a baffle 35. Gases escape from this chamber through a valve 33 and pipe 34. If obstruction occurs and causes oil to accumulate in the chamber 31, a float valve 32 closes the valve 33 until the gas pressure. is sufficient to remove the obstruction. The cooled oil is distilled by being preheated in the exchanger 21 and by passage in succession through the horizontal cylindrical still 12-12<b>. The stills are divided by baffles 46 around which the oil flows and are surmounted by dephlegmators 66 connected to a condenser 69. The stills are fitted with coils for passage of superheated steam to control the temperature and with perforated pipes for injection of steam or gas into the oil.

Title: Improvements in and relating to alternating current electric circuits comprising capacity and saturable inductance
IPC: H01H47/34
Filed: 1933-05-24
Abstract: 420,085. Automatic regulation; electromagnetic switches; impedance networks. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. May 24, 1933, No. 15018. Convention date, May 26, 1932. [Class 38 (iv)] In A.C. circuits comprising self-saturable inductance 13, capacity 12 and resistance 11 in series, which exhibit large changes in current for small changes in volt - age at a critical applied voltage, the variation which this critical circuit voltage experiences with variation in the supply frequency is under- or over- or completely compensated by supplying the circuit from across an element of another branch circuit 14, 15, the voltage across which rises linearly with frequency. The compensation circuit may be a series resistance 15 and inductance 14 across the supply, the voltage-sensitive network being connected across the inductance 14, or the network may be connected across a resistance which is in series with a condenser across the supply 10, the resistance in the former case being large, and in the latter case small, relative to the reactive impedance of the compensation circuit. Alternatively the compensation circuit may comprise capacity, inductance and resistance in series across the supply, adjusted so that at normal supply frequency the circuit operates on the point of inflection of its frequency resonance curve, so that with rising frequency, the voltage across one of its elements rises linearly. The voltage-sensitive network may be connected across any one of the impedances of the tuned compensation circuit but, for minimum effects due to harmonics in the supply voltage, it is connected across the resistance. The circuits may be used in control apparatus where the sensitivity of a relay or contactor switch may be increased by energizing it from across an element, such as the condenser of the voltage sensitive network. The arrangement may be used to control voltage-regulating equipment and may be energized from the voltage to be controlled so as to provide automatic regulation thereof. The Specification as open to inspection under Sect. 91 disclosed arrangements in which the series sensitive circuit was energised from an inductance in a parallel tuned circuit including resistance in each limb of the tuned circuit, or, alternatively, from a resistance in one limb of the tuned circuit which was connected to the supply in series with a resistance. This subject-matter does not appear in the Specification as accepted.

Abstract: 972, 707. Photocopying; optical fibre devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 26,1961 [May 2, 1960], No. 15053/61. Headings G2A and G2J. In a photocopying apparatus the original document is scanned by a strip of light, which is reflected from a plurality of longitudinally-aligned discrete areas lying along the strip, and transmitted so as to fall on corresponding areas of a photosensitive copy sheet spaced apart from the original. In the form shown, the original document 7 is traversed from left to right (Fig. 2) between guide plates 1, 2. At the same time, by a suitable drive means, the light-sensitive copy sheet 8 is traversed in the opposite direction, at the same speed, between guide plates 3, 4. Illumination is provided by light or ultra-violet sources 40, 41, having reflectors 42, 43 and lenses 45, 46 so that a single intense line of light 47 is produced, extending transversely across the sheet 7. As the sheet passes through the apparatus, it is "scanned" by the line of light. The light reflected from sheet 7 is transmitted to sheet 8 by an arrangement consisting of a plurality of fine optical fibres 50. These are of a material such as glass or quartz, having a thin transparent coating, and then cast in a block 55 of epoxy resin. Thus an image of the text on sheet 7 is formed on sheet 8. The ends of the fibres should be as close as possible to the sheets 7, 8 without actually touching.

Title: Improved means for controlling the cyclic operation of components of a power plant
IPC: F02C5/06
Filed: 1942-10-28
Abstract: 595,546. Free-piston compressors. ENGLISH ELECTRIC CO., Ltd., and WELSH, R. J. Oct. 28, 1942, No. 15121. [Class 8 (i)] [Also in Groups XXVI and XXXV] Free-piston internal combustion compressors L.M.N.P., are started and stopped as the demand for power increases and decreases in the same cyclic order by a system of control units L83, M83, N83, P83, each associated with two adjacent power units in cyclic order, and thus the power units give approximately equal service. The control system is disclosed as a fluid pressure system but by substitution of electric relays for the various piston-actuated fluid-valves, the control can be effected by an analogous electric system. Fig. 4 shows schematically the position of the various control valves with power units M, N, and P, in operation. Pressure applied to "stopping" line 77 is only transmitted through line L77, and through valves L95 and L91. From valve L95, pressure is applied via line P99 and valve M91 to " stopping " device L70 but without effect as unit L is at rest. From valve L91 pressure is applied via line L99 and valve N91 to "stopping" device M70, thereby causing device M to stop. Pressure applied to starting line 76 is only transmitted through line P76, valve P85, line L98, valve L87, and line L75, to " starting " device L49 thereby causing device L to start. A " running indicator associated with each power unit moves the associated valves, e.g. L85, L87 and L91 in the case of unit L, to the right if the unit is inoperative, and to left if the unit is operative. If all power units are operative then a " stopping " signal is arranged to stop that unit that was first to be started. Thus upon starting unit L with units M, N, and P, already operative, pressure in line L75 is applied to a piston device to move valve L95 to the left and another piston device to move valve M95 to the right so that the next '' stopping " signal is directed to the stopping device M70. The " starting " and " stopping " signals can be given by a manually actuated valve or alternatively may be given by an automatic valve responsive to the load on the whole plant. Specification 595,547, [Group XXVII], is referred to.

Abstract: 561,910. Electron oscillators. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 29, 1942, Nos. 15199 and 15200. Convention dates, Oct. 30, 1941. [Class 39 (i)] In an electron discharge device having electrodes for generating a modulated stream of electrons and for collecting the stream, the output electrode 16 comprises a number of segments surrounding the path of the stream and separated by gaps parallel to the longitudinal axis of the stream and means are provided to cause the electrons to travel in helical paths within the output electrode past the gaps between the segments. The output circuit comprises conductors 22 joined to the segments and provided with a conductive plunger 23 movable in a shield 24 to connect them at a variable point for tuning purposes. A coupling loop 25 connected to a utilisation circuit extends through the plunger. The shield 24 has tubular extensions to shield the discharge tube. Electrons from the cathode 11 pass through a grid 12 and then, if desired, through a velocity modulating arrangement involving a resonant cavity tank circuit 33 as shown. The stream then becomes subject to a radial electrostatic field due to an electrode 18 and also to a magnetic field due to electromagnet 26 and the electrons are thus caused to follow helical paths through the output electrode 16 before being collected on electrode 13. If the device is being used as a mixer, an input signal may be introduced by a loop 21 to the transmission system 19 connected to the grid 12 while the local oscillator voltage may be introduced by loop 37 projecting into the resonant cavity 33.

Abstract: 859,377. Electrodialysis. PERMUTIT CO. Ltd. (Permutit A. G.). May 16, 1957 [May 17, 1956], No. 15414/56. Drawings to Specification. Class 41 A continuous electrodialytic process in which streams of electrically conducting liquids are passed through a cell divided into compartments by ion-selective membranes while a direct current is passed through the cell, comprises breaking the electrical continuity of one at least of the liquids, e.g. by causing the liquid to travel over part of its course in the form of discrete droplets, at a point between the cell and a place at which the liquid is at earth potential. The liquid, which may be the emergent, concentrated water from a multi-compartment cell in which anionic and cationic permselective membranes are arranged alternately, may be broken up into droplets by passage through a box having a number of outlet holes in its base, the drops falling through air to a collecting vessel. Alternatively, the water droplets may fall through an immiscible, non-conducting liquid of lower specific gravity, e.g. decane, or rise through a similar liquid of higher specific gravity, e.g. perchlorethylene. Incoming water to be desalted may be similarly broken up. The process ensures that no low resistance path exists between the liquid, e.g. incoming or outgoing, and earth.
