Title: Controlling the power of a nuclear reactor plant comprising steam generators
IPC: F22B35/00
Filed: 1966-06-29
Abstract: 1,131,547. Controlling reactors. BROWN BOVERI/KRUPP REAKTORBAU G.m.b.H. 29 June, 1966 [1 July, 1965], No. 29295/66. Heading G6C. In a nuclear reactor power plant, a negative temperature coefficient of reactivity is provided and reactivity control is effected by variation of the reactor coolant inlet temperature. The reactor coolant gas is circulated through a steam generating heat exchanger. A heat exchanger feed water heater may be used or heating of the feed water effected by steam tapped from the turbine low pressure stage. The reactor coolant exit temperature may be maintained constant by the adjustment of the coolant inlet temperature. Rapid alterations of the reactor coolant temperature, as hence also the reactor power, may be effected by throttling the coolant flow.

Title: Improvements in or relating to production of ceramic rods having helical surface indentations
IPC: B28B11/08
Filed: 1950-11-30
Abstract: 691,334. Making helically-grooved ceramic rods &c. BOSTLUND, G. Nov. 30, 1950 [Dec. 7, 1949], No. 29385/50. Class 87 (ii) [Also in Group XI] A method for producing ceramic rods having in their outer surface one or more grooves following a helical line comprises feeding soft ceramic material through the outlet of a rod-extending press and, as the material exudes from the press, forming a groove in its surface by relatively-rotating shaping means, subsequently cutting the extruded material into lengths and thereafter subjecting those lengths to drying and burning. A cutting wire 114 is fixed at 116, 118 to a ring 112 which is rotatable, on a ball bearing, concentrically with the extrusion outlet 104 (106 being a core). The radial distance of the wire from the centre of the outlet, which determines the depth of cut, is adjustable by arms 120, 122 and screws 124, 126. To keep the wire taut a spring 128 presses on it. To clear scrap material a cleaner 132 is adjusted so that its end is slightly further from the centre than the wire. A supply of raw material is placed in a detachable cylinder (not shown in Fig. 1) which is supported on a base 22. In the piston 12, Fig. 4, which fits in the cylinder, is a recess 84 covered by a plate with a keyhole slot 90, 92 which fits over a ball head 80 on the end of a screw-threaded spindle 56. The other end of the spindle 56 carries an arm 68 which is guided on a rod. 70. A chain wheel 58, on a bushing 60 threaded to fit the spindle 56, is driven from a driving wheel 34, which also drives a shaft 42. A belt and pulley drive is taken from the shaft 42 to the rotatable ring 112. As the driving wheel 34 is rotated by a motor 30 the piston 12 advances and material is extruded through the opening 104, and the shaft 42 rotates and causes the ring 112 to revolve the cutting wire 114 round the material as it emerges, in which it therefore cuts a helical groove. One of the arms 120, 122 may be bent to alter the inclination of the wire and so to vary the width of the groove cut by it. If the die is shaped to extrude a non-circular section a series of notches in a helical path will be cut. Abutments 74, 76 on the rod 70 are engaged by the arm 68 at the limits of its stroke and move the rod 70 to operate a switch 78 to start or stop the motor. The machine may also be controlled by foot. A screen is arranged round the rotary cutting tool to receive scrap material. The extrusion cylinder includes a filter. Cut lengths of extruded and grooved material may, after drying and before firing, be trimmed by a tool which comprises bushes having cutting faces, the distance between which is adjustable.

Void [Abridged as open to inspection under Sect. 91 of the Acts, April 28, 1934]. [Class 135] An inflating - valve has a casing 2 with spaces 5, 6 at each end communicating with each other by a valve guiding passage 12, the outer space 5 being threaded to receive a closure plug 19 or alternatively the screw coupling of an air pump, and the inner space 6 being closed by a screw plug 14 which is adjustable to regulate the lift of the valve cone 10. Air passes through grooves 20 in the valve spindle or in the wall of the passage 12. Air vents 16, 17 are provided to the space 6. The valve 10 is held to its seat by a cap 18 screwed on the valve spindle. The nut 3 by which the casing is clamped to the inflated article 1 is surrounded by a protecting ring 22. In the open position, the valve cone abuts an elastic pad 15. In a modification, this pad is replaced by a spring, and a single screw cap bearing against a washer serves to clamp the valve and to close the outer space 5.

Title: Improvements in gas ducts
Inventor: GODSHALK RUSSELL LYNN
IPC: F16L9/04
Filed: 1961-08-16
Abstract: 914,323. Gas ducts. BABCOCK & WILCOX CO. Aug. 16, 1961 [Aug. 18, 1960], No. 29541/61. Class 25. [Also in Group XXVIII] A gas duct has walls formed of plates and strengthening means including circumferentially spaced longitudinally-extending ribs and longitudinally spaced frames extending perpendicularly to the ribs. In the embodiment of Fig. 1 the duct 20 comprises plates 21-24 joined together by welding along their edges. L-section ribs 25 are welded internally to each wall of the duct along the edge of one limb 25A of the rib, the other limb 25B being parallel to the walls and in the case of the side walls extending downwardly to prevent the formation of a gutter in which dust or ash would tend to accumulate. Suitably “-inch welds are used to secure the ribs, of 2-inch length, spaced on 9-inch centres. External frames 26 of U-section girders are secured by spaced welds to the duct, the distance between the frames being at least twice the distance between the longitudinal ribs. Tie-bars 27 extend across the duct and are welded at their ends to plates 28 which extend through slots in the side walls 22 and 24 and are welded to the frames 26, the slots in the side walls being closed after assembly by welding. Insulating material 30 is applied to the outside of the duct and is humped as necessary over the frames 26. Fig. 3 (not shown) illustrates a similar duct, the L-section ribs being replaced by U-section ribs which on the side walls are inverted to prevent gutter formation. In the construction of Fig. 4 the ribs 45 are of U- section and the circumferential frames 46 are internal and are welded to the longitudinal ribs. Transverse angle-section members 48 and 49 are welded to the frames 46 to give additional strengthening. Figs. 5-8 (not shown) illustrate other arrangements of internal bracing and Figs. 9 and 10 (not shown) illustrate suitable bends for connecting two ducts at right-angles. Ducts of the above types have dimensions of the order of 10 ft. x 30 ft. and are suitable for the transport of combustion gases from steamgenerating units.

Title: Antenna system
IPC: H01Q13/10
Filed: 1946-10-04
Abstract: 628,584. Aerials. STANDARD TELEPHONES & CABLES, Ltd. Oct. 4, 1946, No. 29656. Convention date, June 19, 1945. [Class 40 (vii)] In a slot aerial comprising a conducting member formed with an aperture across opposed edge portions of which energy transfer (i.e. feeder) means are coupled for establishing a plurality of spaced current maxima, means are provided for creating impedance to the occurrence of current maxima in certain areas of said member. In the arrangement of Fig. 1, in which a circular aperture 2 is provided in a conducting sheet 1, the impedance means comprise small slits 10, 11 ... 13, cutting the path between the feed terminals 2a, 2b of those points at which the undesired current maxima would otherwise be established. In an arrangement in which three elongated slots are formed in a conducting sheet (Fig. 2, not shown) the operative extent of the sheet associated with each slot is determined by suitably positioned slits (as in Fig. 1), and additional slits crossing the latter slits are provided to set up effective impedances between the three radiating areas. An arrangement producing a radiating area having two current maxima 20a, 20b, has the desired area defined by a circular skirt 23, Figs. 3 and 4. In a modification of the latter arrangement the skirt instead of being circular is comprised of two sections extendirig parallel to the slot (Figs. 5 and 6, not shown). Instead of employing a skirt as in the arrangements of Figs. 3 to 6 the operative extent of the radiating surface may be defined by a plurality of fins arranged parallel to the slot, in the case of an elongated slot, or, when the slot is in the form of a cross (Figs. 7 and 8, not shown), by a plurality of circular circumferential fins. In the arrangement of Fig. 9, the operative extent of the radiating surface 33, underlying a main metallic surface 34, is determined, because of aerodynamic considerations, by the opening 35 in the latter surface. The opening may contain a non-conductive protective material to effect streamlining and to shield the surface # 33. In the arrangement of Fig. 10 a - slot 36 2 A is fed at points 38 ... 40, and a - slot 37 mid- 4 way of and at right angles to the slot 36 effectively separates the portions 42, 43 thereof so that the latter portions function as separate slot aerials. In a further arrangement (Fig. 11, not shown) two cross-shaped slots are formed in the surface of a conducting cylinder and the desired operative extent of the surface is determined by suitably-positioned impedance slits.

Title: Process for the preparation of anthraquinone
IPC: C07C46/02
Filed: 1976-07-16
Abstract: Naphthalene is oxidised using a gas containing oxygen and inert gases in the presence of a vanadium-containing catalyst to give a mixture which contains naphthoquinone, phthalic anhydride and naphthalene. This liquid product is reacted with butadiene in an excess, a liquid mixture being produced which essentially contains tetrahydroanthraquinone, phthalic anhydride and naphthalene. Anthraquinone is obtained from tetrahydroanthraquinone by oxydehydrogenation of this mixture. The components are concentrated by means of a distillation system. The process permits the preparation of anthraquinone from naphthalene in a continuous manner. As a result of the recycling, virtually all the product streams produced in the process are used again. Product losses and environmental pollution are kept low by this means. Anthraquinone can be used as a starting material for the preparation of dyestuffs. The phthalic anhydride formed as a by-product can be used as a starting material for the preparation of plasticisers and for many other chemical syntheses.

Abstract: 1,149,490. Fluid-pressure servomotor systems. FABBRICA ITALIANA MAGNETI MARELLI S.p.A. July 1, 1966 [July 1, 1965j, No.29769/66. Heading G3P. [Also in Division F1X] A vehicle pneumatic regulating system includes a first chamber 1, having a compressed air inlet 11, in communication with a pressure regulator 2 through a check valve 5 and an intermediate chamber 4, at least one additional check valve 46, 48 communicating at least one additional chamber with the intermediate chamber, the pressure regulator opening the outlet valve when the pressure in at least one additional chamber exceeds a predetermined value. Compressed air is received through port 11 and passes via filter 12 and condensate separator 13 into chamber 4 through duct 16 and check valve 5. From chamber 4 air passes through passage 22 to chamber 21 and through check valves 45, 46, 47 to respective plant section chambers. When pressure rises above the predetermined value in any section chamber and hence in chambers 4 and 21 a spring-loaded valve piston 23 rises to admit air to chamber 30 whilst closing valve 27 thus cutting-off the venting of chamber 30 to atmosphere via passage 26. Pressure acting on piston 32 which is connected via rod 62 to outlet valve 15 opens the latter to reduce the pressure in the system. When pressure reduces to the predetermined value piston 23 seats on seal 24 and chamber 30 is vented to atmosphere via valve 27. Chamber 4 has a port 41 for an intake 42, a low-pressure indicator 43 and a condensate drain valve 44.
