Title: Apparatus and processes for concentrating and evaporating liquids
IPC: B01D1/22
Filed: 1956-06-11
Abstract: <PICT:0799618/III/1> <PICT:0799618/III/2> In an apparatus for the heat - exchange treatment of liquids, wherein the liquid, introduced by one or more inlets 40, is caused to rise as an annular film on the wall of the vertical cylindrical chamber 10 by means of centrifugal motion imparted by the vanes 55, the treated liquid is deflected by an obstruction 47 at the top of the chamber into a tangential discharge outlet 60. The apparatus may be used for the evaporation of liquids, e.g. in concentrating solutions, or for effecting chemical reactions in which case a liquid may be introduced by one inlet and a separate liquid or gas through another, similarly a liquid catalyst or dispersion of catalyst particles in a liquid may be introduced by a separate inlet. Liquids may be introduced under pressure. The walls of the chamber are heated by steam or other heating fluid passed through the two heating chambers 17 and 18 formed by the outer cylinder 16, separated by the ring 19, and each having an inlet 20 and an outlet 21. More heating chambers may be provided and alternatively electrical heating may be used. The top of each vane 55 is shaped with a short horizontal portion 57 and a downwardly slanting edge 58. The bottom surface of the plate 46 has a level portion 47 constituting the obstruction and a depending lip 59 which interfits with the slanting edges 58 of the vanes. The rising liquid is deflected into the spiral or involute channel 44 and thence into the tangential outlet 60. The lower corners of the vanes 56 may be chamfered. Vapours leave by exit tube 50 formed with a trap to collect escaping droplets of liquid. High or low pressures may be used if desired, in the case of vacuum evaporation it is not necessary to collect the liquid under vacuum or to pump out the liquid since the combination of the dam and the vanes give sufficient centrifugal force to cause an outward pressure and flow of liquid. Examples are given of the concentration aqueous gelatin and of a dispersion of silver halide in aqueous gelatin.

Title: Apparatus for the Collection and Logarithmic Measurement of Quantities of Charges Produced by an Ionization Chamber
IPC: G01T1/185
Filed: 1967-11-18
Abstract: The total charge produced in an ionisation chamber in response to a pulse of radiation is measured by transferring a substantial predetermined portion of the charge to a low-leakage capacitor and subsequently discharging the capacitor through a high resistance. The capacitor voltage is fed through a high impedance input e. g. an electrometer tube or a field effect transistor to a trigger circuit which produces a pulse when the capacitor voltage reaches a predetermined threshold. This pulse samples a saw-tooth voltage to pick-off a voltage proportional to the logarithm of the initial charge on the capacitor and this voltage is displayed on a log scale meter. The ionisation chamber and capacitor may be separate from the remainder of the apparatus so that one measuring unit may serve a plurality of ionisation chambers. The apparatus may be used to measure pulses from accelerators or X-ray generators or the decay of radio-elements or used in photometry.

Title: Traction motor control system
IPC: B60L15/10
Filed: 1970-04-11
Abstract: Traction motors M1-M4 with fields F1-F4, controlled in both motoring and braking modes by a chopper circuit 20 receiving ON and OFF signals from a control network via leads 74, 66 respectively, are switched between modes by relays A, B, C, such that A1 closes and A4 opens, or vice versa, while A8, B1, A9 and B2 co-operate to ensure that a gate 68, which transmits the ON pulses to the chopper only if opened by a voltage from 92, remains non- conductive throughout the change of mode. The arrangement is shown in the braking mode, and when relay B is energized by switch S, contacts B2-B4 close after B1 opens, and switches A1-A3 close before A9 closes, whence C1, C2 close. The enabling signal to the gate 68 travels via A8 and B1 in the braking mode and via C1, A9 and B2 in the motoring mode. For motoring the motors M1, M2 and M3, M4 are in series pairs, the pairs connected in parallel, and in series with the chopper 20, smoothing reactor 26, and current detector 91, and for braking, armatures 1 and 2, in series with fields 3 and 4 are in parallel with armatures 3 and 4 in series with fields 1 and 2, all shunted by resistor 24, and resistor 22 intermittently shunted by the chopper to control the braking effort. The chopper comprises thyristors 38, 40 and 42, reactor 46 and thyristor 42 providing a by-pass circuit for the initial current, and 40 being operative for quenching. Pulses are supplied via transformers 52 and 54, 52 having mutually isolated secondaries for thyristors 38 and 40. Diode 28 by-passes the back e.m.f. of the motors when their current is switched off. Oscillator 62 provides OFF pulses Pf to the chopper, on lead 66 at regular intervals, and, after a controlled time delay provided by delay 70 in response to control system 86-88, 90, and comparator 80 which may be a differential amplifier, comparing the desired with the actual motor current, a series of ON pulses P n is supplied on lead 74, provided the gate 68 is open. The control scheme of pulses may alternatively be of the variable frequency or ripple control type. Circuit 88 limits the allowable rate of change of the delay, and shapers 72, 64 may be differentiating circuits. Overcurrent protection 98, 100, 102, OL-1, OL-2 may be provided, although C2 may be operated directly by relay A, and overcurrent protection omitted.

Patent ES-403637-A1 (ES)
Title: Step motor and controls for non-oscillating punch/read positioning of 80-column record cards
IPC: G06K13/077
Filed: 1972-06-08
Abstract: A high precision high speed bidirectional step motor assembly, without gears or commutation, rapidly and precisely positions standard 80 column record cards without oscillation relative to a combined reading, punching and printing station of a card data recorder. Read cells and punch-print elements are separated by 2 units of card column displacement (2 x 0.087 inches). Four step drive excitation for the step motor (three drive pulses and one "hold" or "detent" pulse) is derived from pre-existing recorder circuits associated with buffer storage and logic sections. This permits reading, punching and printing operations to occur in synchronization with buffer and logic operations while card motion is definitely stopped in the holding stage of the motor drive cycle. A pressure roller which engages the card with a feed wheel extension of the step motor is disengaged either manually or by operation of conventional registration mechanisms as the cards are fed to the initial registration position of the combined station (card column "0" under punch and print elements column 2 under read cells). In read mode the first dummy cycle of step motor excitation backs up the card one column returning column 1 of the card to the read position. The advantage of this is that the read cells can be utilized in a dual mode to detect the leading edges of cards as a condition of the registration operation and to read card apertures. In punching-printing mode the usual first "dummy" cycle of forward stepping is taken.
