Patent GB-648891-A (GB)
Title: Method of evaporating or distilling liquids
IPC: C08G69/16
Filed: 1947-07-10
Abstract: Organic liquids and aqueous solutions are evaporated by circulating the liquid through a heat-exchanger and an evaporator, mechanically-compressing the vapours liberated in the evaporator, and passing the compressed vapours to the heat-exchanger where they condense and give up heat to the liquid; the amount of liquid circulated in unit time being 300-1500 times the amount of liquid evaporated in unit time.  Preferably the amount of liquid circulated is 800-900 times the amount of liquid evaporated, the total energy required for circulation of the liquid and compression of the vapours being a minimum at this ratio.  A similar method, but applied specifically to the distillation of water, forms the subject-matter of Specification 641,429.  In the evaporation of aqueous liquids, e.g. whey containing 60 per cent dry matter, the vapours are compressed at a compression ratio of 1.1-1.9 which corresponds to a temperature difference in the heat-exchanger of not more than 10-12 DEG  C.  The inlet and outlet channels of the compressor are so dimensioned that the pressure-loss therein corresponds to a temperature decrease of vapour of only 0.2-0.4 DEG  C.  In the case of the evaporation of heat-sensitive liquids, the compressed vapours are de-superheated, e.g. by injection of water, before they are admitted to the heat-exchanger.  Fixed gases such as nitrogen, oxygen and carbon dioxide, are withdrawn by means of a pump.  The compressor may be a turbo-compressor, a fan-blower, or a piston pump; and may be driven by electricity, steam or an internal combustion engine. The evaporation of milk is referred to.

[Also in Division G3] In spark erosion apparatus, movement of the tool electrode is controlled by a circuit including an AND gate 1 having two inputs 9 and 10 at least one of which is dependent upon the spacing between the tool and workpiece electrodes; the output from the AND gate is applied as one input to a bi-stable circuit 2 having a second input connected to a regulating unit 3 which delivers a signal at regular intervals of time. The two outputs 4 and 5 of the bi-stable circuit 2 are connected to the drive mechanism of the tool electrode, a signal on 4 producing a " forwards " movement and a signal on 5 producing a " backwards " movement. The signal on output 5 is produced only when two signals are present at 9 and 10, and the signal on output 5 is produced at regular intervals through the operation of unit 3; the inputs to 9 and 10 are dependent on the operating conditions and are derived from the current pulses, the no-load voltage pulses, the forming voltage pulses or the control voltage pulses which occur during the operation of the apparatus. Arrangements, some of which include two AND gates, suitable for the various combinations of output signals are described with reference to Figs. 1 and 3 to 14 (not shown). The outputs 4 and 5 may be applied to the electrode drive mechanism by way of further logic circuits, including AND or OR gates (Figs. 15 to 17, not shown).

Abstract: 279,179. Thorrowgood, W. J. July 26, 1926. Signal lamps; lantern screens.-In a route-indicating signal lamp in which an indication is given by projecting an illuminated numeral, letter, symbol or other device on to a screen, a green, blue, or violet tinted glass screen is employed to change the yellowish tint of the light from an ordinary oil or gas flame or an electric light into a white tint known as " lunar white " so as to avoid the indication being mistaken for an ordinary yellow traffic-controlling signal. In order to increase the range of visibility of the indication, one or both surfaces of the tinted screen may be etched or otherwise made translucent, or a separate translucent screen may be arranged in front of or behind the tinted screen. In the form shown in the Figure, a lamp casing 1 carries an electric lamp bulb 2 at the focus of a Fresnel or stepped lens 3 behind or in front of which is arranged a single fixed stencil screen 4 or a number of movable stencil screens bearing different indications. The front of the casing is provided with a sun hood 7, and with a cylindrical cover 5 for the tinted screen 6. If the lens 3 is not optically perfect, the sides of the steps of the lens may be blackened or otherwise rendered opaque to prevent the projection of non- parallel rays.
