Filed: 1943-07-26
Abstract: 569,889. Hygrometric apparatus. MARCONI INSTRUMENTS, Ltd., and BARTLEY, W. B. July 26, 1943, No. 12136. [Class 97 (iii)] The moisture content of a porous or granulated &c. substance is determined by applying high-frequency electrical energy to the substance and ascertaining the loss of weight of such substance during such application. As shown, the apparatus employed comprises a direct reading balance B having a weigh pan p, a pair of condenser plates e,-carried by operating insulated tong handles t, an oscillator circuit o including a valve v and a control and high-tension circuit c including a source of high-tension energy H.T., a switch b, a no-load release d and an oscillation frequency choke h. The oscillation circuit is connected to the condenser plates as shown. In operation, a very light paper bag pb is placed on the weigh pan p and filled with the substance until the scale B indicates full scale reading. The condenser plates e are then adjusted to touch the sides of the paper bag and the switch b closed. Generation of oscillations commences and continues until the substance, being dried, has lost so much moisture that the power loss has reached some predetermined low figure when the noload release cuts off the high tension and, if desired, may light an indicating lamp. The loss of weight of the substance as indicated on the scale B, then indicates the moisture content driven off. In place of a condenser, a solenoid or resonant cavity may be used.

Title: Improvements in or relating to absorption refrigerating apparatus of the intermittent type
IPC: F25B15/10
Filed: 1934-04-23
Abstract: 437,370. Refrigerating. ELECTROLUX, Ltd., Luton.-(Assignees of Platen-Munters Refrigerating System Aktiebolag; 2, Norrmalmstorg, Stockholm) April 23, 1934, No. 12157. Convention date, April 25, 1933. [Class 29] Absorption systems.-A rapid reduction of pressure and evaporator temperature at the end of the generating period of a reversing system is effected by exposing vapours above the level of the generator liquid to a cold stream of solution withdrawn from a store of continuously cooled solution in a vessel located outside the generator. The flow of the cold stream is induced by the flow of vapour from the evaporator. The generator is in the form of a narrow vertical tube 13 provided with a heating coil 13b surrounding a heated flue 31, and the strong solution is supplied thereto from the upper part of the continuously cooled storage vessel 11 by a pipe 19 passing through a liquor heat-exchanger 12 and formed into a coiled " pumping " pipe 13<a> around the flue. The gas rises from the generator through a narrow tube 16 to a separator 38 fitted with baffles and then descends, together with any liquor, a jacket 39 around the tube 16 and passes to a collector vessel 41. The gas bubbles through liquid in this vessel and rises through a tube 18 to a rectifier 60 and a condenser 14. Condensed refrigerant flows through the rectifier jacket to a receiver 15<a> above the evaporator 44, which may be drained by a valved pipe 59. Above and communicating by a passage 49 with the storage vessel 11 is a vessel 21, the upper part of which communicates by a pipe 51 with the separator 38 and therefore with the gas space of the generator, and by a U-tube 11<d> with the lower part of the storage vessel. The upper part of the vessel 41 is connected by a pipe 42 with the lower end of the U- tube 11<d>. During the heating period any gas passing into the vessel 21 by the pipe 51 is absorbed by the liquid in the vessel until a filin of saturated solution forms thereon and retards further absorption ; no substantial condensation of refrigerant takes place there. On cessation of the heating period the gas remaining in the separator 38 and tube 16 is absorbed by liquid present therein and a pressure drop occurs in the generator and therefore in the vessel 41. Gas from the condenser and evaporator, now at a slight excess pressure, readily passes down the pipe 18 into the vessel 41 and thence by the pipe 42 to the U-tube 11<d>, where it is absorbed, resulting in a further reduction of pressure and an increased flow from the evaporator, which effects a lifting action on liquor in the pipe 11<d>. The liquid falling down in the vessel 21 breaks up the saturated film and absorption proceeds in that vessel. The generator and heat-exchanger may be insulated by spaced foil sheets, and the vessel 41 may be insulated or be arranged in heat exchange with parts of the generator. The storage vessel and the condenser may be cooled by water coils 55, 56, preferably of copper, or may be gilled for air cooling.

Title: Method of and apparatus for effecting the evaporation of liquids
IPC: B01D1/06
Filed: 1920-05-05
Abstract: 166,004. Merz, F. May 5, 1920. Evaporating and concentrating plant and processes; vapours, utilizing for effecting further evaporation.-Liquids to be concentrated, such as sugar syrups, fruit or tomato preserves, or liquids to be freed from water, such as perfumes or explosives, are distributed over one surface of a heat-conducting material, or of a thin tube or plate, a liquid that absorbs the evolved vapours is distributed over the other surface, and a current of air or gas is circulated from one surface to the other. The latent heat evolved on absorption of the vapour is thus transferred to the liquid undergoing evaporation. In evaporating water from a liquid which may contain solid matters, sulphuric acid or solutions of calcium chloride, soda or potash, or sea water, may be used as the absorbing-liquid. The heat-conducting material may be in the form of a rotating horizontal nest of tubes 7, Fig. 1, mounted in plates 8 fitted with hoods 11, 12 which receive an absorbing-liquid which flows into the interior of the tubes when in their lowest positions. The drum rotates in a bath 2 of liquid to be evaporated, and is enclosed in a chamber 1 in which air or gas is circulated by a pump 20, first through the tubes and then over the exterior of the tubes. Air baffles may be formed by plates 14 attached to the tubes and with openings at the centre, and partitions 15 in the chamber 1. An electric heater 24 may be enclosed in a chamber 1. When drying perfumes or explosives, a cooling-device may be used. The tubes 7 may be made of glass and the tube plates 8 of rubber, which is stretched over the hoods 11, 12. The nest of tubes may be vertical and stationary, the liquid to be evaporated being circulated from a bath 2<1>, Fig. 3, by a pump 26, pipe 25, and a rotating distributor 34, into a bath 31 divided by radial partitions, from which the liquid flows down the interior surface of the tubes, and the absorbing-liquid being circulated from a bath 27 by a pump 30, pipe 28, and a rotating distributor 35 into a bath 33 from which the liquid runs down the exterior surfaces of the tubes. The tubes are enclosed by a casing 1<1> and air is circulated by a fan 20<1>. The temperature may be regulated by a pipe 40 through which hot or cold liquid may be circulated. The heat-conducting material may be in the form of a series of vertical parallel plates 7", Fig. 5, which have their alternate edges joined together so that liquids supplied by distributors 46, 46<1>, which are moved backwards and forwards over a series of plates, flow down the opposite sides of the plate. The two liquids are collected in receptacles 43, 44 from which they are returned to the receptacles 48, 48<1>, which supply the distributors. Air circulation is effected by fans 20". The apparatus may be used to remove ammonia from ita solutions and absorb it in water.

Title: Radiation Recording System.
IPC: G02F1/15
Filed: 1968-03-14
Abstract: 1,190,673. Light modulators. BAUSCH & LOMB Inc. 14 March, 1968 [20 March, 1967], No. 12561/68. Heading H4F. [Also in Division G1] A light-modulating element comprises a solid state layer 10, Fig. 1, of ionic conducting material including a solid matrix having therein a mobile anion and an electrolytically-reducible metal ion (cation), layer 20 of photoconducting material, and electrodes 30 and 32 for applying an electrical potential to the layers 10 and 20, whereby when the photoconducting layer 20 is exposed to radiation (visible or invisible) it conducts electrons to the ionic layer which reduces the metal ion changing the optical characteristics of the element e.g. optical density, and forms an opaque image. When irradiation of the photoconductor 20 is ceased or the circuit opened (switch 42) the image is retained in the matrix 10. The image may be viewed directly since transmitted light is partially blocked by those portions which are electrochemically darkened, or it may be viewed by reflection of light from the direction of electrode 32. To erase the image switch 44 is closed and layer 20 uniformly exposed. A pattern may be formed in the matrix by one spectral range (e.g. infra-red or ultra violet and viewed by a second spectral range (e.g. visible), Fig. 2 (not shown), a beam splitter being disposed adjacent the modulating element. The absorption and refractive characteristics of the matrix material may be changed instead of its optical density, and the element may contain more than one reactive matrix layer. Certain combinations, of matrix layers and electrode layers produce PN junctions having photoconducting properties, i.e. a separate photoconductive layer is not needed. To measure the amount of radiation incident on the photoconductive surface, co-ordinate electrodes 30, 32 are coated on opposite sides of multilayer 10, 20, Figs. 3 and 4, the leads 30L and 32L being used to bias the multilayer and for readout of the electrical charge by means of a scanning circuit 46 having means for measuring the developed potential in the storage device. In operation light rays form a pattern at layer 20 by passing through partiallymetallized mirror 54 supported on a slit cube 52, the matrix layer 10 being energized by biasing the individual portions of the layer simultaneously or sequentially during irradiation. To read out the recorded optical pattern the layer 20 is illuminated uniformly by light source 60 via diffusion plate 62 and the leads 30L and 32L are connected in time sequence to the individual electrode bars. The ionic conducting material may comprise compositions of lead fluoride or glasses having particular mol. ratios (see Specification). The ionic layer may comprise a strontium-doped lanthanum fluoride film disposed between lead fluoride films.
