Title: Process and apparatus for the measurement and/or the control of a flow of matter from or into a vessel
IPC: G05D11/13
Filed: 1966-07-06
Abstract: 1,149,629. Measuring and controlling fluid flow. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. July 6, 1966 [July 8, 1965], No. 30333/66. Heading G1N. Flow of fluent matter from a container 1, Fig. 1 through a valve 7 is measured by comparing at 4 the output A of a transducer 3 responsive to pressure or weight of matter in the container, with a voltage B from a unit 5, any difference between them causing the output unit 5 to continuously increase in discrete steps until the said difference is zero. The frequency of the stepwise increase is proportional to rate of flow, and is measured at 6, this signal also being used to control the flow valve 7. A meter 8 indicates total flow. One of two containers (9, 9a, Fig..3 not shown) is connected to an outlet (2) by a selection valve (10), and to a weight-or pressure-measuring device (12) by a switch (11) the output of which feeds a valve or transistor amplifier (15) (corresponding to amplifier 4, Fig.1) via a resistor (19). The second input to amplifier (15) is via a resistor (20) from an amplifier (14) (forming part of unit 5 of Fig. 1), the input being equal to the voltage stored on a capacitor (16). When the output of amplifier (15) exceeds a threshold value set in a threshold device (21) a switch (22) operates intermittently to charge the capacitor (16) from an auxiliary capacitor (23), to remove the difference. The frequency of operation of the switch (21) is indicated (at 24), and may be integrated to show the amount of matter which has flowed, either by means of an electronic integrator, or with a pulse motor and stepping potentiometer. An analogue signal is produced (at 25) proportional to the frequency, and controls a flow valve (26). Changeover (at 10) of the outlet (2) to the second container (9a) automatically switches (at 11) the transducer (12) to the second container. Switchable resistors (29, 30) are provided across the amplifier (14) and storage capacitor (16) to set up the circuit at the beginning of an operation. The unit 25 may include a required load pre-set circuit Fig.4 (not shown) comprising a capacitor charging circuit similar to that associated with amplifier (14), the switch (33) being driven in synchronism with switch (22) and a reference voltage being supplied through an adjustable resistor (35). A mixture control arrangement Fig. 5 (not shown) employs a ratio controller (42) and two flow measuring arrangements, one or both of which may be as described. The weight of material in the container may be measured by a strain gauge load cell.

Abstract: 690,225. Controlling filling of containers by penetrative radiation. ROSE BROS. (GAINSBOROUGH), Ltd. Nov. 28, 1950 [Nov. 29, 1949], No. 30516/49. Class 40 (iii). The density of a powder is detected by means of penetrative radiation. The invention is described with reference to the cartonfilling device described in Specification 690,215, [Group XVII]. As shown, powder falls from a hopper 11 through one of a number of apertures 13 in a wheel 14 on to a flap 19. This flap is lifted at intervals to fill a container 23 situated below a further hopper 22, this hopper being mounted on wheel 20 which rotates with wheel 14. A beam of penetrative radiation such as X-rays or Beta rays passes from a source 26 through the container to a detector 27. Detector 27 actuates a meter 28 calibrated in terms of powder density. The meter may be provided with limit switches so that if the powder density lies outside certain values, a . motor 29 may vary the hopper capacity by axial movement of wheel 20 to ensure that each container receives a constant weight. Since the radiation beam is directed across the upper part of each carton, if a container does not fill correctly, meter 28 may operate mechanism to reject the carton.

Abstract: 477,443. Control of several D.C. motors. ENGLISH ELECTRIC CO., Ltd., CARNEGIE, H. S., and WILSON, J. C. June 29, 1936, No. 30836 /37. Divided out of 476,901. [Class 38 (iii)] A Ward-Leonard ship propulsion equipment including port and starboard propulsion motors fed from a common generator has separate and independently operable port and starboard motor controllers, each controller having a resistance regulator for varying the separate excitation of the corresponding motor or exciter therefor and a resistance regulator for switching on and varying the separate excitation of the common generator or exciter therefor, so that step-by-step movement of the controllers together varies the speed of both motors together, while relative movement of the controllers varies the relative excitations and speeds of the motors. The generator field 1 and the port and starboard motor fields 2, 3 are connected in independent circuits across the supply by the mechanically independent port and starboard controllers 4, 5. Movement of either controller from the central " off " position in either direction cuts resistance 8 or 10 out of the generator field 1 and increases the field of the corresponding motor for forward or reverse running by moving contacts 13, 14 or 16, 17 along potentiometers 15, 18. Alternatively, each potentiometer may be replaced by a reversing switch and means for cutting a series resistance out of the motor field circuit, and the motor fields may be reduced to zero as soon as the generator field 1 is switched off at 7, 8 and 9, 10, but preferably, as shown, the motor fields 2, 3 are weakly excited for braking purposes in the one or more positions of the controllers on each side of the " off " position corresponding to the gaps in the resistances 8, 10. Modifications. The generator unit may comprise a plurality of generators and the two propelling units may each comprise a plurality of motors. The controllers may alternatively regulate exciters for the generator and motors and the generator or exciter therefor may have in addition a series decompounding field winding and a third field winding supplied by the voltage of the generator or exciter for enhancing the effect of any change in excitation. The decompounding effect may be introduced only when a critical load is exceeded, for example, as set forth in Specification 472,472, in which case the third generator field winding may be regulated by both controllers similarly to the field 1 and the fixed resistances 11, 12, inserted to prevent overloading, may be made small or omitted. Alternatively, the resistances 11, 12, associated respectively with the controllers 4, 5, may be cut out step-by-step by movement of the other controller, or they may be cut out in one step as the other controller reaches the full-on position. Compounding and other field windings may also be included on each motor or exciter therefor. Specification 349,012 also is referred to.

Abstract: 1,197,185. Separation of solid potassium chloride from brine. M. P. SWEENEY. 11 July, 1967 [11 July, 1966], No. 31049/66. Heading B1B. [Also in Division C1] Potassium chloride is separated from an aqueous solution of KC1 and NaCl by a process comprising flash evaporation of water from the solution, and' the addition to the solution of a water-miscible organic solvent such as .pyridine and/or N-methyl morpholine. In an example, a stream of hot makeup brine '(depleted of KC1) is used to dissolve KC1 from a mineral deposit comprising KCl and NaCl and the stream of return brine (rich in KC1) is concentrated by flash evaporation, the watervapour being condensed by contact with cool makeup brine. The flash evaporation causes precipitation of some of the KC1. The slurry is mixed with a solvent comprising pyridine and N-methyl morpholine, and the mixture is passed to a flash decanter where some of the solvent is vaporized, and the liquid cools with further precipitation of KC1. A concentrated slurry is removed from the base of the flash decanter, and is centrifuged to obtain the solid KC1 product. The liquid removed from the side of the flash decanter is warmed by condensation of solvent-vapour therein (see below), and then passed to a settling vessel where it separates into two liquid phases. The aqueous phase is stripped with steam to remove residual solvent, and the vapours are condensed in the liquid mixture flowing to the settler. The stripped solution is cooled by flash evaporation of water, and is recycled as makeup brine. The vapour evolved in the flash evaporation is condensed in the stream of organic phase leaving the settler, and the solvent vapours evolved from the organic phase are condensed in the stream of liquid mixture flowing to the settler. Other suitable organic solvents mentioned are the picolines, 3-methyl pyrrolidine, dimethylaminotetrahydrofuran, ethyl dimethyl amine, diethyl methyl amine, and dimethyl (2 methoxyethyl) amine. The precipitation of magnesium hydroxide from an aqueous solution is referred to.
