Abstract: 1434019 Sulphonation of aromatic compounds A KOEBNER 24 Oct 1973 [30 Oct 1972] 49928/72 Heading C2C A process for the sulphonation of aromatic substances having a boiling point not greater than 100‹ C. at a pressure of 0À1 mm. Hg, said substances being aromatic compounds containing at least one -CH= group and susceptible to the direct action of sulphur trioxide to yield a product having a sulphonated aromatic nucleus but otherwise substantially inert under the reaction conditions to sulphur trioxide and mixtures thereof, wherein:- (1) said aromatic substance at a temperature above its melting point, and thus in liquid form, is brought to boiling in a reaction chamber at a temperature not exceeding 100‹ C., under a pressure of from 0À1 mm. Hg to atmospheric pressure; (2) gaseous sulphur trioxide is introduced into the boiling liquid aromatic substance to react exothermically therewith, heat liberated in the exothermic sulphonation reaction causing said liquid aromatic substance to continue to boil and furnishing the latent heat of volatilization of the said liquid aromatic substance; (3) the aromatic substance thus volatilized is reconverted to liquid in a heat-exchanger, so that latent heat of volatilization is given up in the heat-exchanger and heat liberated in the sulphonation reaction is thus removed from the reaction chamber; (4) the aromatic substance reconverted to liquid in the heat-exchanger is recycled to the reaction chamber, and (5) the pressure in the reaction chamber and the rate at which the gaseous sulphur trioxide is introduced into the liquid aromatic substance are so controlled that the aromatic substance is volatilized, reconverted to the liquid state and recycled to the reaction chamber at a rate such as to ensure that the amount of liquid aromatic substance present in the reaction chamber and available for participation in the sulphonation reaction is always in excess of that amount of said aromatic substance capable of reacting with the gaseous sulphur trioxide in contact with the aromatic substance in the reaction chamber, and that the temperature of the reaction mixture does not exceed 100‹ C. Many sulphonatable aromatic compounds are specified, including benzene, naphthalene, anthracene, indane and thiophene compounds. The process may be carried out continuously, involving separating the unreacted aromatic compound from the reaction mixture, purifying it and recycling to the reaction chamber. A separate apparatus is described for each of batchwise and continuous processes.

Title: Charging and pretreatment installation of a packing press for radioactive waste material
IPC: B09B5/00
Filed: 1975-12-05
Abstract: 1528478 Treating radio-active waste KERNFORSCHUNGSZENTRUM KARLSRUHE GmbH 5 Dec 1975 [6 Dec 1974] 49978/75 Heading G6R [Also in Division B4] In a charging and pretreatment installation of a packing press for radio-active waste material, which press is accommodated in a housing 10 and charged from above, a sealed glove box system 6, 7, 8, 9 is arranged above the press for the pretreatment of the waste material before pressing, adjacent glove boxes in the system being interconnected via coupling apertures 17, 48, 49. Waste material to be packed or baled is delivered to the sorting box 6 in an iron-hooked drum 79 which is moved by means of a conveyer 79A to below the flange 36 of the double cover (cf. B4-B5 abridgement) when this is in a horizontal position. The flange of the drum 79 is screwed to the flange 36. The drum 79 is then hoisted by means of a cable winch 25 and rotates about a hinge 35 so as to be tilted towards the box 6. By opening the double cover upwards into the box 6, the waste material drops out of the drum 79 on to a perforated plate 22 within the box 6 below which a trough 21 is located to collect liquid. The waste materials are sorted or graded in the box 6. Combustible substances, or substances which cannot be packed, are removed through an aperture 80. The whole plant is then evacuated through an extraction system 24, 71. The waste material is then fed through the aperture 17 into the filling box 7 from where it is fed through a filling shaft 11 into the pressing cylinder 1 which has been rotated about a central column 15 to a position beneath the shaft 11. When filled, the cylinder 1 is rotated through 120 degrees to below the actual pressing piston (not shown) and pressed into a cake. A further 120 degree rotation brings the cylinder 1 beneath an ejection piston 2 which presses the cake into a drum 4 which is forced against the press by a lifting device 3. Used extraction air filters are charged via a pocket 73 closed by a flap 74 into the filter comminuting box 9 and combustible pre-filters are comminuted by means of a circular saw before being discharged in a container which is incinerated together with its contents. Other filters are transferred via the aperture 49 into the ejection box 8 in which a stamping device (Fig. 3, not shown) is used to separate the filter material (e.g. fibreglass mat and aluminium foil) from the combustible wooden or plastics frame. The filter material in then fed via the aperture 48 into the filling box 7 and hence into the pressing cylinder 1. The contents of the cylinder 1 are bulky but very soft and are pre-pressed by means of a device 47 located over a charging aperture 46 in the base of the box 7. As a result, the main pressing operation may only be necessary after each second or third charge. All operations are performed via the glove couplings, e.g. 20, 51, 56, 69, 70, 76, 77, in the glove boxes 6, 7, 8, 9 by means of the glove technique.

Member 10 controls fuel flow from a supply pump to the injection pump, supply fuel entering chamber 16 via inlet 17 and passing via passages 18, 19, 20 to a chamber 21 from which four passages 22 radiate and, on rotation of member 10, sequentially register with injection pump inlet/outlet 24 during the injection pump suction stroke. Four radial recesses 23 in member 10 sequentially register with inlet/outlet 24 during the injection pump delivery stroke, and transmit the pump delivery to a chamber 26 communicating via passage 27 with a metering member. Fuel from the metering member passes through passages 28,15 and 30 to a recess 31 in member 10. Recess 31 has a radial extension 32 which, diving station of member 10, sequentially registers with a plurality of passages 33 leading to the engine cylinders. Hydraulic balancing is effected by dividing the adjacent faces of the valve members into pairs of lands by annular grooves 37 and (35) (39) Fig 3 (not shown) in the faces of valve member 10, the lands being subjected directly and via passages 36, 38 to the pressure of the fuel delivered from the injection pump to the metering member and to the pressure of the fuel delivered from the metering member to the cylinders. The end face 12b of valve member 12 is subjected to the fuel pressure from the metering member and a face 41 on member 12 is subjected to the injection pump delivery pressure in chamber 26 to balance pressure forces acting between members 10 and 12. In the Fig. 6 embodiment, which is of reduced bulk, balancing pressure acts between an intermediate cap 114 and valve member 112, and an alternative arrangement of the lands between valve members 112 and 110 is provided.

Filed: 1968-10-30
Abstract: 1,201,969. Drawing. MANCO MFG. CO. 30 Oct., 1968, No. 51414/68. Heading B3P. A die for a tube shaping or pointing machine comprises a plurality of spaced-apart blade members 72 for engaging a workpiece and has either a bar member 84, Fig. 7, interconnecting and retaining the blade members 72 against deflection relatively to each other or a workpiece engaging extension means 200, Fig. 9, projecting outwardly from an endmost blade member. In one embodiment, four dies having bar members 84 are arranged around a tube 22 to be pointed with a vertical pair of dies displaced forwardly by a distance equal to one blade thickness relative to a horizontal pair of dies. The blades 72 are thus interleaved when they are moved radially inwardly to compress the tube end by wedge members 36 moved by an hydraulicallyoperated ram 40. The radial inward movement of the dies is limited by the longitudinallyextending bar members 84 circumscribing the tube 22. In another embodiment for pointing soft metals wherein the use of a bar member 84 is unnecessary, a conventional pair of bladed dies are positioned for vertical movement relative to a pair of horizontally movable dies shown in Fig. 9, so that the outer surfaces of the blocks 200 are coplanar with the outer surfaces of the forwardmost blades of the vertical dies. The compressed tube is engaged by the blocks 200 which prevent it from extruding between the spaced-apart blades of the vertical dies. The die shown in Fig. 9 may be replaced by a die having a bar member (84b) (Fig. 13, not shown) extending forwardly of the forwardmost blade 72 by one blade thickness. The bar member 84 may be integrally formed with the base of the die.

Abstract: 1484859 Dispersive surface wave delay lines MARCONI CO Ltd 12 Sept 1974 [6 Nov 1973] 51562/73 Heading H3U  In a dispersive surface wave delay line of the kind which, as shown in Fig. 1, has a reflective array of fingers 10, 11, 12, on a piezo-electric surface, the spacing between the fingers being graded so that waves of different wavelengths are reflected by different portions of the array, the amplitude of the reflected waves of selected frequencies is reduced by displacing some of the fingers from the nominal positions shown in Fig. 1, the amount of the reduction being determined by the amount of the offsetting. As shown in Fig. 2 alternate fingers are displaced so that the fingers form pairs 10a-10c, 12a-12c, the distance between fingers of a pair being less than, and the distance between adjacent pairs being more than the nominal finger spacing, i.e. #/2 for a wavelength of #. The fingers may be in the form of grooves etched in the piezo-electric substrate, e.g. lithium niobate, or deposited insulating or conductive material e.g. silicon oxide, aluminium or titanium. The two Rayleigh surface wave components in quadrature are changed by variations in the depth of the groove or the amount of deposited insulating material, one of the components being changed proportionally, the other in proportion to the square of the depth or thickness of deposit. When the fingers consist of electrically conductive material, they may be electrically isolated, or interconnected at one or both ends and preferably also between their ends. In another embodiment (Fig. 3, not shown) the launching transducer sends acoustic waves from one end of the piezo-electric bcdy which are reflected through 90 degrees by a first set of graded fingers disposed at 45 degrees, and reflected through a further 90 degrees by a second set of angled fingers. The reflected waves are received by a transducer adjacent the launcher. Selected fingers of one or both sets of fingers may be displaced to suppress predetermined frequencies as before. This embodiment may be used for pulse compression.

Abstract: 1,243,019. Charging batteries. HUGHES AIRCRAFT CO. 5 Nov., 1968 [23 Feb., 1968], No. 52311/68. Heading H2H. In a battery charging system, one or more batteries are first discharged in two stages and then recharged at a constant current for a preset time. In the embodiment shown, two batteries 22, 24, which may be of different types, are discharged and charged simultaneously using separate circuits. The battery 22 is connected by way of a lead 42 through a control unit 20 and lead 54 to a discharge unit 26, causing discharge initially through a resistive load 56. When the battery voltage, sensed by a circuit 58, falls below a set level, a relay 1K is activated so that the battery is now connected to a constant current discharge circuit 60. When the voltage falls below a second set level, sensed by a circuit 62, the battery 22 is automatically disconnected from the discharge unit 26. In the meantime, the other battery 24 has been similarly discharged by the unit 28, and when both batteries have been discharged they are then connected to charging circuits 74, 76 respectively. At this time, a supply is also sent through an inverter to a timer unit within the control unit, and after a preset time, the batteries are automatically disconnected and the system is returned to its "discharge" mode. The system may include separate timing units for each battery. Indicator lamps 110, 112, 114 show the current stage of the charging process. The batteries are positioned on spring-loaded bases 30, 46, so that if a battery is removed during operation, a mechanical signal is sent by way of links 44, 48 to the control unit, resetting the apparatus to its initial condition. A manual reset is also provided. The system of relays within the control unit is described with reference to Fig. 3 (not shown) and circuits for the constant current discharge units, the voltage sensing units, and the charging circuits are given in Figs. 4-6 (not shown). These circuits include transistors and Zener diodes.
