The arrangement of baffles to cause the required flows may be as shown in Figs. 3 or 4a, the flow of heavy phase being indicated by double arrows L, and of light phase by arrows K. The process may be used for the separation of dimethyl terephthalate from a suspension using methanol, separating xylene and acetic acid using water, washing glass microspheres with water, and extracting soya beans with hexane.

Abstract: 1291429 Magnetic storage devices BANKER RAMO CORP 8 Oct 1970 [8 Oct 1969] 48026/70 Heading H3B A magnetic wire memory-comprises a conductive carrier plate apertured to receive plated wires and etched so that it contains drive lines for the wires. The initial step in the formation of one aperture and its associated drive lines is shown in Fig. 4, where a conductive plate 22, e.g. of beryllium copper, is etched at 24 to form a groove around central portion 25. The floor of the groove 24 is then selectively etched, Fig. 6, to increase the depth of the inner and outer parts of the groove and leave a raised central portion 29. The groove is then filled with a dielectric material 30, and the other side of the plate is etched at 34, Fig. 9, to isolate the raised central portion shown as 39. Further etching gives a structure as in Fig. 10, with an aperture 32 through which a plated wire may be passed and a pair of drive lines 39 supported by the dielectric 30. Similar etching steps elsewhere on the plate gives an array of apertures linked by drive lines, Fig. 1 (not shown). As an alternative to Fig. 10, the drive lines 39 may border the aperture 32 rather than be separated therefrom by the innermost portion of the dielectric material, Figs. 12-15 (not shown), though this necessitates insulation on the plated wires. Several plates may be stacked with their apertures aligned to give a three dimensional store. Conductive and/or magnetic layers may be deposited on the plates to reduce coupling between memory cells and also reduce disturbances by the earth's field.

The speed of a brushless electric motor having a rotor position sensing device operating at high frequency, is controlled by a shaft mounted centrifugal switch which cuts off the high frequency supply to the sensing device when the motor overspeeds. A high frequency oscillator 1 induces a high frequency signal in coil L 4  on the rotor through rotating transformer T 1  and this signal is applied through the centrifugal switch contact G to rotating coils L 5 , the number of such coils depending on the number of poles on the permanent magnet rotor. Detecting coils are spaced around the stator frame, with opposite coils connected in series, and the magnitude and phase of the voltages induced, from coils L 5 , in these coils will be a measure of the instantaneous rotor position. These values are added to a reference signal induced in coil L 3  and after detection are applied to a transistor switching circuit for causing current flow in the motor stator windings L 9 -L 11  in sequence. If the motor overspeeds contact G opens to cut off the high frequency supply to coils L 5  and thereby stop the supply of current to the stator windings so that the motor speed falls until contact G again closes. The opposite direction of rotation may be obtained by reversing the output of reference coil L 3 . Alternatively the switch may operate to short-circuit coil L 4 .

Abstract: 1375013 Automatic control of reactive power B B C BROWN BOVERI & CO Ltd 26 Oct 1971 [28 Oct 1970] 49769/71 Heading G3R [Also in Division H2]  An induction crucible furnace having induction coils R1, X1 &c. and compensation capacitors C1, C4, &c. also incorporates further capacitors C10, C11 selectively shuntable by a switching network S1-S6 across any of the coils, the network being controlled by compensation and load balancing regulators which respond to respective current transformers f1, f4 &c. On the assumption that the compensating reactive power is always greater than the highest balancing reactive power, all the reactive power components can be combined into a capacitor bank which includes capacitors C10, C11 (shown schematically in the figure). It is stated that each capacitor C7-C9 has a power rating which is such as to compensate the maximum inductive power of its coil, and is coupled to transformers fl, f4 &c. in such a way that no compensating action appears to be required and so that the available balancing power therefrom appears to the balancing regulator to be an inductive one. This regulator then causes S1-S6 to switch enough capacitance from C10, C11  to make up the difference between the required balancing power and the apparent inductive reactive power provided by C7 &c.

Title: Apparatus for the measurement of dye dilution in blood
IPC: G01N21/31
Filed: 1964-12-08
Abstract: 1,095,114. Measurement of dye dilution in blood. ATLAS-WERKE A.G. Dec. 8, 1964 [Dec. 9, 1963], No. 49924/64. Heading A5K. [Also in Division G1] The measurement of dye dilution in blood, in order to determine cardiac volume parameters, in which a dye is injected into the circulatory system at one region and a photoelectric colour measurement performed at another region, involves the measurement of absorption levels of the blood at at least three different wavelengths, one of which is the wavelength at which the natural isosbestic point of blood lies, the other wavelengths being selected in accordance with the particular test dye used. The effect on these levels due to variation in the O 2  saturation, of the blood, its concentration C and the test layer thickness D are compensated for by suitable settings of the measuring apparatus and the taking of difference, sum or proportional values of the measured levels. The apparatus used comprises a source L directing light through the test object C such as a cuvette or the ear, the light transmitted being received by three cells P each of which has associated with it a monochromatic filter F. The wavelengths passed by the filters are chosen so that one passes light which has been subject to absorption by the dye, which maybe for example methylene blue, or cardiogreen, oxidised haemoglobin (HbO 2 ) and reduced haemoglobin (Hb). The second and third filters pass wavelengths outside the absorption spectrum of the dye and thus the light affected only by Hb and HbO 2 . Any one of the wavelengths may be chosen to be that at which the natural isosbestic point occurs, i.e. when the absorptions of Hb and HbO 2  are equal and, at which wavelength, measurements are unaffected by the O 2  saturation level. Further, the other two wavelengths are chosen to produce a considerable difference between the measured absorption levels at these wavelengths. The outputs of the detectors are each fed to logarithmic amplifiers V L  with variable amplifications, or other circuits, which convert the absorption values to logarithmic (or "extinction") values so that logarithmic procedures according to Beer's law may be carried out to give uncompensated indications of dye concentration at the three wavelengths on monitoring instruments K. Special circuitry (Fig. 6, II and III) may be used to consider the three signals from the cells as containing three unknown quantities, i.e. the dye concentration and the two unwanted variations in O 2  saturation and product C.D., and by performing various subtraction, addition and comparison operations in these signals, the compensated value of the dye concentration is obtained and indicated on a meter.
