Title: Separation of emulsions
IPC: B01D17/02
Filed: 1975-12-12
Abstract: 1526839 Settling tanks K O WIKHOLM 12 Dec 1975 [16 Dec 1974] 50979/75 Heading B1D Apparatus for separating an emulsion of water and petroleum products, resulting from washing of vehicles, machined parts etc., comprises a stack of flat rectangular settling tanks 11 arranged in a common outer casing (Fig. 1, not shown) and fed from a common vessel (17) at the top, the vessel (17) including heaters (26) and overflow pipes (16) leading to inlets 12 of respective tanks 11. Each tank 11 has an inlet chamber 43 defining a gap 48 extending almost the full width of the tank to deliver emulsion as a thin layer at a level just below layer P of previously separated petroleum products. A timer controlled pump (32) delivers emulsion from a buffer tank to vessel (17) and thus to tanks 11 for a given period and then stops to allow the emulsion to separate. Emulsion is fed into each tank 11 until its forward edge reaches wall 39, where perforate baffle 51 inhibits its sinking. Pump (32) is able to run only when the emulsion in vessel (17) is at a predetermined temperature range, and the elevated temperature assists gravity separation in tanks 11. Each batch of emulsion fed into tanks 11 displaces previously separated petroleum products over a weir (13, Fig. 6 not shown) and displaces water through gap 57 into auxiliary settling chamber 52. Chamber 52 has two weirs (14) and (15) which respectively discharge impure water from the top and pure water from the bottom of chamber 52 (Figs. 2, 4, 5 not shown). Weirs (13, 14, 15) of the various tanks discharge to common conduits (18, 19 and 20), from which the recovered petroleum products pass to a storage tank (not shown), which may have a high level alarm signal switching off pump (32), the pure water passes to a sewer and the impure water, still containing some petroleum products, is recycled either to vessel 17 or to the washing plant for re-use. The outer casing is a thermally insulated box with a top vent for gas. Heaters (26) are fed with hot water under control of thermostat (29, 30).

Abstract: 1,017,789. Moderating neutrons. REACTOR CENTRUM NEDERLAND. Dec. 15, 1964, No. 51088/64. Heading G6P. A neutron moderating plug 1 is formed as a tank containing heavy water and is supported in the concrete mass 9. A neutron beam enters at 10 and has a spectrum of the form 11 in which those neutrons having the highest velocity are at the beam centre. Neutrons moving downwards in the region of the centre line pass through a greater length of water than those following the path 14, 15 and are thus subjected to a greater moderating effect. Neutrons moving from the beam are deflected back into it along path 17.

Abstract: 511,746. Float-actuated valves. CROSS, R. C. Dec. 20, 1938, No. 37019. [Class 135] In a cistern-supply valve of the type having two floats 7 and 13, the first of which provides the closing force and is released by the second float when the water has risen to a certain height, a balance weight 9 moves the float 7, at low water level 11, past the dead-centre position 10 so that the valve 2 remains fully open until at a predetermined upper level 15 the float 13, by means of the lever 14 engaging the arm of the float 7, returns the latter through the position 10 so that the valve is closed quickly. The closing force is transmitted by an eccentric 4 on the shaft of the float 7 engaging a crosshead 6 secured to the valve 2.

Abstract: 1,190,498. Data processing in exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 30 Oct., 1968 [7 Nov., 1967], No. 51487/68. Heading H4K. In an exchange system one of a number of processors working in parallel is nominated in cyclic order for each processing cycle to take on all new exchange tasks initiated in a cycle, further processing required for any task being continued in later cycles by the processor that took up the task initially. As shown in Fig. 1, an exchange GE sends data to two processors R1, R2 by way of register E and receives processed data by way of register S. The processors Ri, R2 have logic sections RW1, RW2, input buffers ER, output buffers AR, and individual or common storage facilities Sp. The processors are nominated to handle task initiation in alternate processing cycles. At the beginning of each processing cycle instructions from one processor are read out to register S while the other processor takes the task data from register E. In an immediately subsequent time slot of the cycle the one processor takes the exchange task data from E while the other processor is read out to S. Each processor sorts through the task data from E to find its own work and, if so nominated, to take on new work.

Abstract: 1299586 Automatic current control BORGWARNER CORP 3 Nov 1970 [5 Dec 1969] 52238/70 Heading G3R [Also in Division H2] An automatic control system for the motor 20 driving the compressor 12 of a refrigeration system 10 comprises a plurality of comparators 52, 54, 56, 58 each receiving a respective reference signal 61, 63, 65, 67 and the output signal 40 from a unit 36, which signal is representative of the largest current in any of the phases Q1, Q2, Q3 of the motor 20, the comparators supplying signals to circuits 28, 30 controlling the pre-rotational vanes 13 of the compressor 12 and to circuits 70, 74, 76 controlling the contacts 26 in the supply to the motor 20 such that the following operations are obtained if the motor current rises above its normal full load value: - (1) above reference signal 61 and below signal 63, the signal from comparator 52 inhibits operation of the temperature regulator 30 (which controls the setting of vanes 13 through the motor 28) to prevent further increase in loading of the motor 20 due to adjustment of the vanes. (2) above reference signal 63 and below signal 67, the signal from comparator 54 actuates the regulator 30 to adjust the vanes 13 to reduce the load on, and hence the current of the motor 20. (3) above reference signal 67 and below signal 65, the signal from the comparator 58 actuates circuits 70, 74, 76 to open contacts 26 after a predetermined (long) time delay. (4) above reference signal 65 the signal from comparator 56 actuates circuits 70, 74, 76 to open contacts 26 after a predetermined (short) time delay. As shown in Fig.2 the unit 36 comprises rectifier bridges 81, 82, 83 receiving signals representative of the motor phase currents and connected so that the largest signal back biases the other two rectifiers before being passed to a peak detector circuit 39 via a calibration control 38. The comparators 52, 54, 56, 58 take the form of Schmitt Triggers each comprising an operational amplifier 100---103 and associated circuitry, the pairs of amplifiers 100, 101 and 102, 103 each being formed on a common substrate chip. Circuit 70 comprises a timing capacitor 130 which, when charged, fires a uni-junction transistor 160 to turn on a silicon controlled rectifier 170 and so energize a relay coil 154 whose contacts 155 open to de-energize the coil 77 of the motor controller 76 having the contacts 26. The signal from comparator 58 also energizes an alarm indicator lamp 180. Under operating condition (3) the charging time of capicitor 130 is determined by resistors 126, 128, but another condition (4) the signal from comparator 56 makes a transistor 140 conductive to short out the resistor 126 and so reduce the time to operate members 160, 170 and 76. The timer 70 also includes a current limiting and temperature compensating resistor 142. Operation under various overload conditions is discussed, Fig.3 (not shown) and the effect of various sequences of overloads is explained.
