Title: Method of extraction in continuously operating liquid phase extraction apparatus
IPC: B01D11/04
Filed: 1960-04-14
Abstract: 892,783. Liquid phase extraction. ALLMANNA SVENSKA ELEKTRISKA A.B. April 14, 1960 [April 15, 1959], No. 13304/60. Class 46. The extraction apparatus comprises a pulsed column 1. The lighter organic phase introduced at 3 is homogeneous and the transition zone consequently lies at the lower end 2 of the column 1, the heavy phase being introduced at 4. The outflow of the light phase occurs at 5 while the heavy phase leaves mainly at 6. The outflow of the heavy phase may, for example, take place with the help of a pulsing means 9 which is connected to the lower end of the column via a conduit 10. In this case a non- return valve 11 prevents the reflux and the regulation of the flow is carried out with the help of the valve 12, the liquid outflow taking place at 13. A pump can be used for this purpose. A cleaning circuit is connected to the lower end of the column at 14 which is in that plane at which the interface 15 is intended to be, and consists of a filter unit 16 and a level regulating device 17, the object of which is also to distribute the two liquid phases which are led through the filter unit. The device 17 consists of a cylindrical vessel 18 with a riser 19 for the lighter phase and a riser 20 for the heavier phase. The risers are provided with outlets 21 and 22, respectively, which are adjustable vertically. The outlets 21 and 22 are set at such a level that the phases reach the outlet level when the transition zone 15 in the column is at the level of the connection 14 of the branch conduit 23. At the level at which the branch conduit is connected, the column is provided with a guiding screen 24 which conducts the impurities from the transition zone towards the branch conduit. Fig. 2 shows another embodiment of the regulating device 25. Outlets 21 and 22 are at the liquid level reached when the transition zone 15 is at the level of the branch conduit 23. A guiding screen 24 directs the impurities from the transition zone to the branch conduit. Another similar cleaning device is illustrated in Fig. 2 (not shown).

Title: Apparatus for use in moulding or producing articles of glass
IPC: C03B11/06
Filed: 1929-04-30
Abstract: 328,445. Mitchell, W. B. April 30, 1929. Addition to 302,193. Pressing.-Relates to the rotary pressing- apparatus described in the parent Specification and consists in forming each mould so that several articles are produced simultaneously, and in forming each pressing-plunger so that it is used to eject the finished articles from the moulds. The mould consists of a solid body a, Fig. 2, with a removable bottom portion a<1> and a, cylindrical top portion b for receiving the molten glass, the top b being made, as usual, of two parts hinged together. The pressing-plunger c enters the cylinder b and presses the glass through perforations into a number of moulding-cavities formed in the parts a, a<1>. The cavities, in the construction shown, are shaped to form stoppers for bottles. After the glass is pressed, the hinged sections b are opened and the mould is carried by the rotation of the machine to the next operating-position. During this movement, the body a passes beneath a blade which shears off the excess glass d<2>. The bottom a<1> also moves clear of a support f and swings away from the body a. The plunger c is again lowered, and pins c<1>, which project from its lower face, enter the perforations in the upper part of the body a and force the finished articles out of the mould. The sections b are kept closed during the pressing- operation by a yoke h, Fig. 6, as described in the parent Specification. The plunger c is pivoted to one end of a lever k which is pivoted at k' to the frame of the machine. The lever carries a roller k' which is engaged by a cam to operate the plunger. The hinged parts b of the mould are connected by adjustable links to a lever which is pivoted to the frame of the machine and is operated by a fixed cam.

Abstract: 1,126,542. Transistor pulse circuits. NATIONAL CASH REGISTER CO. 25 March, 1966 [26 May, 1965], No. 13347/66. Heading H3T. In a logic circuit coincidence of data and clock pulses at 10,12 turns off transistor 26, allowing capacitor 64 to charge negatively until transistor 56 becomes conductive, initiating an output pulse at 14. The output from transistor 56 is fed back to the base of transistor 26 so as to inhibit the clock circuit, hence the output pulse at 14 continues until the end of the pulse at 10 even if the clock pulse at 12 has terminated. Capacitor 64 ensures that no output will be provided for pulses at 10 of less than a predetermined duration. The level-shifting Zener diode 52 may be replaced by a resistor. The input at 10 is provided by relay contacts (not shown), resistor 28 being fed from a - 50 V supply so as to remove oxide formed on the contacts.

Title: Improvements in or relating to x-ray tubes and circuit arrangements
IPC: H01J35/04
Filed: 1957-04-26
Abstract: 860,758. X-ray tubes. RILEY, D. P. April 21, 1958 [April 26, 1957(2)], Nos. 13466/57 and 13467/57. Class 39(1). [Also in Group XXXV] In an X-ray tube comprising three or more pairs of electrodes, each pair consisting of a cathode and an anode, the electrodes are so arranged and adapted for connection to a poly-phase electric supply that each cathode can emit electrons to two anodes and each anode can receive electrons from two cathodes. As shown in Fig. 3, the electrodes may be coplanar, or arranged on a conical surface, each of the anodes 2, 4, 6 being provided with two tungsten targets 26, 27 and having a tube 21 arranged therein for connection to a supply of cooling fluid. Each of the cathodes 3, 5, 7 has a helical filament 14 arranged behind elongated slits 17, 18 in the shield 8. In an alternative arrangement the cathodes and anodes are arranged at opposite ends of the tube with their axes parallel. Both the cathodes and anodes are equi-angularly disposed about the tube axis, cathodes and anodes facing each other and being staggered in angular disposition. The cathodes are similar to those shown in Fig. 3 but each of the anodes has a flat end face in which a single target is provided. In operation of a tube having three pairs of electrodes each anode is connected to the cathode from which it does not receive electrons and these pairs of electrodes are connected to the apices of delta-connected high-tension secondary windings of a three-phase step-up transformer so that each anode emits X-rays continuously for two-thirds the period of each cycle and the total emission of X-rays from the tube is continuous and of nearly uniform intensity. In a further embodiment each pair of electrodes forms a unitary structure comprising a tungsten anode 30, Fig. 9, and a filamentary cathode 34 supported by anode skirt 32 and formed as a zig-zag grid in front of the target face 31, three such structures having coplanar axes radiating from a central point at angles of 120 degrees to one another. The cathode may be connected directly to the anode or may be insulated therefrom as shown. In the latter case the cathode may be connected to the anode by way of an adjustable resistor so that the anode acts as a repelling plate for electrons emitted by the cathode and the cathode acts as a control grid when the structure is receiving electrons from a second electrode pair.

Title: Thermionic valve circuits
IPC: H03F1/54
Filed: 1955-05-11
Abstract: 804,607. Valve circuits. ALLMANNA SVENSKA ELEKTRISKA A.B. May 11, 1955 [May 11, 1954], No. 13612/55. Class 40 (6). A thermionic valve circuit for performing a function comprises two groups of at least two valves each valve normally performing the function and the valves being connected together so that in the event of any valve becoming open-circuited or appearing as a shortcircuit the other valves or the unaffected group still perform the function, In Fig. 1 two groups of series-connected valves 11, 12 and 13, 14 are connected in parallel to a common load 22 and are driven in parallel from a signal source 19 so that an open-circuit or a shortcircuit in any valve still permits the circuit to operate. In an alternative arrangement (Fig. 2, not shown) the anodes of valves 11 and 12 are connected together. In Fig. 5 the valves are connected through a rectifier arrangement to the common load 74, the rectifiers being so biased that in the event of an open-circuit or short-circuit fault in one valve the circuit continues to function. If the anodes of valves 54 and 55 are connected together rectifiers 62 and 63 may be omitted and if the anodes of valves 68 and 69 are connected the corresponding rectifiers may also be omitted, but rectifiers 71 and 72 must be reversed (Fig. 3, not shown) unless the outputs are derived from the parallelled cathodes of the valves (Fig. 4, not shown). In Fig. 6 the input signal is applied through a terminal 110 to two identical amplifiers operating in parallel. Each comprises two parallelconnected valves 80, 81 feeding two further valves 84, 85 connected through rectifiers 86, 87 to a similar series of valves 90, 91, 94, 95 feeding parallel cathode followers connected through a rectifier to the common output terminal 111. An open-circuit or short-circuit occurring in any of the valves 80-95 either permits the parallel valve to operate or makes the final valves 98, 99 or 101, 102 of the corresponding amplifier appear as a short-circuit. The final valves are connected together in accordance with the invention so that in the event of such an apparent fault or a fault in the final valves the circuit continues to function.

Title: Improvements in or relating to stop-valves for compressed air, steam and other gasesand liquids
IPC: F16K17/00
Filed: 1940-08-30
Abstract: 537,210. Stop valves. TAYLOR, W. B. Aug. 30, 1940, No. 13633. [Class 135] A stop valve for compressed air, steam &c. is constructed so that, if the valve PV closes on its seat S after it has been opened by unscrewing the spindle VS; the valve cannot be opened again until the spindle is screwed down so that its conical end engages a hole H3 in the top of the valve. The valve PV is formed as a hollow cylinder with a mitred bottom M to fit the seat S. The valve is pressed on its seat by a spring F<SP>1</SP> in its closed position and is formed so that its head is a sliding fit in the valve body D<SP>1</SP>, and its stem slides in the part D<SP>2</SP> of the valve body. If fluid pressure acts in the pipe A<SP>1</SP> and the screw VS is screwed outwards the fluid pressure on the valve causes its head to follow up the spindle and the valve remains open while the pressure persists in the pipe A<SP>1</SP>. If this pressure falls the spring F<SP>1</SP> depresses the valve head and opens the valve connection between the aperture H<SP>3</SP> and the pointed end of the screw VS. The valve PV is then depressed on to its seat by the spring F<SP>1</SP>, or by its weight, and any increase in fluid pressure cannot open the valve until the spindle VS i again lowered to close on the aperture H<SP>3</SP>. I the pressure in the pipe A<SP>1</SP> rises before the valve is opened, the fluid can pass into a chamber F<SP>2</SP> via passages H<SP>4</SP>, H<SP>5</SP> but when the spindle is lowered to permit opening of the valve the chamber F is vented by ports H<SP>2</SP>, H<SP>1</SP> thus relieving pressure on the head of the valve.
