Title: Improvements in manostat
IPC: G05D16/12
Filed: 1951-02-19
Abstract: 706,777. Fluid-actuated valves. EMIL GREINER CO. Feb. 19, 1951 [Sept. 1, 1950], No. 4034/51. Class 135 A fluid-pressure operated valve comprises a body 7, Fig. 1, e.g. of transparent material, containing liquid 11 on which floats a bell 10 carrying a closure member 24 at its top, a tubular member 13 extending into the body and having an orifice 12 co-acting with the closure member, a tube 22 for guiding the bell, connections 19, 20 for the tubular member and the space above the ball respectively, and a branch 28 from the connection 20 to the interior of the bell. The member 13 is adjustable to vary the setting of the valve. The connections 19, 20 lead respectively to a source of vacuum and a system in which the vacuum is to be maintained constant. A cock 35 in the branch permits a desired control pressure to be locked in the bell which then controls the orifice 12. In a modification for controlling a positive pressure, the connection 19 leads to exhaust and a restricted continuous supply of fluid is admitted to the system. The valve then exhausts the fluid to hold the system pressure constant. In another arrangement, the differential pressure across an orifice 38, Fig. 3, is applied to opposite sides of the bell which controls the exhaust of pressure fluid to maintain the differential constant, positive pressure being supplied through a needle valve 37. In a modification of Fig. 3, the connection 19 leads to a vacuum source, and the direction of flow through the orifice is reversed. In yet another arrangement, the end of member 13 is fitted with a nozzle 45, Fig. 6, containing a closure member 42 seating on a ring 43 and being operated by the bell to control the supply of pressure fluid from connection 19 to connection 20.

Filed: 1977-01-25
Abstract: 1505314 Target display system BARR & STROUD Ltd 25 Jan 1977 [4 Feb 1976] 4312/76 Heading F3C [Also in Division G2] The sight of a gunnery-fire-control target display system includes a dichroic coating 33 between the hypotenuse faces of two rightangled prisms 36, the coating being polerization sensitive and transmissive to radiation entering from an input face 62A of one of the prisms and of wavelength greater than 680 nanometers, while reflective to radiation in the range 425- 680 nanometers. An attenuator (not shown in Fig. 2) is located at the input 62A and/or output 62B face of said prism and comprises (a) a pair of rotatable Polaroid plates at the input face 62A, (b) a rotatable Polaroid plate at the output face 62B, with a dichronic-coated prism pair at the input face but rotated 90 degrees relative to the prism pair 36, (c) at the input, a prism pair as in (b) with an upstream rotatable third prism pair, (d) an input bandstop filter passing only the red and blue, with an output polaroid pair, as (e) as (d) with a red-pass filter instead. The optical characteristics are illustrated. As shown, visible light from a target enters through lens 32 and image rotator 34 for attenuation, polarization and reflection by the attenuator and prism pair 36, for display at an eyepiece 40. An infra-red image of the target produced by a scanner 42 is transmitted through the prism pair 36 on to the eyepiece, which includes a graticle, or on a C.R.T. an elliptical or circular aiming mark (variable in size according to target range) and a triangular bore sight mark (determined from the ballistic parameters). If a phosphor C.R.T. layer is used to produce a green thermal image, then attenuator (d) produces a highly contrasting red and green visible image. A laser 30 bounces a beam off the target for return through the optics to a range finder 37. The range, manual alteration of field of view, weather conditions and ballistic parameters (e.g. calibre and gun barrel bending) are fed to a computer for fire control.

Abstract: 1,143,304. Textile treating apparatus. VEPA A. G. 30 Jan., 1967 [29 Jan., 1966], No. 4431/67. Heading D1L. Apparatus for wetting textile material 19 comprises a container 1 for liquid, a sieve drum 7 rotatably mounted in the container so as to be partially immersed in the liquid, means for conveying the material 19 to the immersed part of the drum 7 at least one partition 9 within the drum dividing it into a pressure chamber 11 and a suction chamber 10, and at least one pump 13 located inside the drum for circulating liquid from the container 1, through the material 19 into the suction chamber 10, thence to the pressure chamber 11 and back to the container. There may be more than one pump 13 situated within the drum and driven, for example by V-belts from a motor 18 located outside the drum. The partition is preferably arranged parallel with the axis of the drum and may be adjustable in position e.g. swung angularly with respect to the drum axis and sealed against the rotating part of the drum. The drum surface may be covered with a coarse wire mesh which in turn can carry a relatively fine wire mesh. The end faces of the drum comprise bearing rings 8 of U cross-section engaging rollers mounted on a fixed part of the respective end faces supported at 33. The inner surface of one end face bearing ring 8 has a toothed formation for engagement with a pinion driven from a suitable motor for rotation of the drum (Fig. 4, not shown). The whole sieve drum unit may be suspended from a cross bar 34 connected with the end faces of the drum and may be lifted in and out of the container as a unit. After treatment on the drum the material passes between squeeze rollers 20 and may then be fed to subsequent wet treating apparatus. The liquid squeezed out by rollers 20 is collected in a tank 23 having a fixed sieve 24 and divided into a first and second zone with an adjustable orifice therebetween (Fig. 2, not shown). With a series of treatment apparatus the tanks 23 may be interconnected so that liquid can flow from the first zone of one tank to the second zone of the preceding tank via pipe 32 and in addition liquid from the second zone of each tank can be pumped by pump 19 via pipe 30 back into the container associated therewith. A part of the liquid sucked into the drum may be passed out via channels 14a through the uncovered part of the drum so that the drum is constantly cleaned.

Title: Improvements in and relating to the production of cocoanut paste
IPC: A23L25/00
Filed: 1939-02-10
Abstract: 524,951. Nut food preparations. NORTHCUTT, R. T. Feb. 10, 1939, No. 4483. [Class 49] A coconut paste suitable for use as a filling for candies and confectionery, or shortening, is prepared by drying coconut meat until the moisture content is below 9 per cent. by weight and then comminuting it at a temperature between the melting point of the coconut fats and the scorching point of the coconut sugars and proteins, i.e., between 75‹ F. and 160‹ F. If the water content is above that stated, a meltable paste cannot be produced, but only a waxy substance which will only dry and char when heated. Fresh coconut meat or copra, which has been hydrated to render it pliant enough for shredding prior to the necessary dehydrating, may be used. Rancidity is preliminarily removed from the copra by treating with weak alkali, e.g., a 5 per cent. solution of hot tri-sodium phosphate. The grinding may be effected in a hammer mill, ball mill or plate mill. The moisture content of the paste is one-half of the moisture content of the dried coconut meat, part of the moisture being used in hydrating the proteins. The paste is non-rancidifying, owing to the low moisture content and, possibly, by the liberation of an anti-oxidant during the grinding. Free oil which may separate out, likewise, does not become rancid, but such separation may be prevented by the addition of 1-2 per cent. of glycerine, water or ethylene glycol to the paste. Alternatively, a mixture of 25 per cent. by volume of alcohol and 75 per cent. of water may be added. When water is added to the paste it rapidly emulsifies to a milky consistency.

Title: Method of sterilizing fruit juices
IPC: A23L2/42
Filed: 1936-02-14
Abstract: Fruit juices are preserved by removing therefrom compounds containing nitrogen and phosphorus which are necessary for the development of fermentation.  The phosphorus may be precipitated from juices at a pH value of less than 4,2 by addition of ferric hydrate or of a ferric salt which will give ferric hydrate with the bases in the juices. The phosphorus and nitrogen may be precipitated in the form of alkaline earth phosphates or ammoniacal alkaline earth salts by making the juices alkaline by addition of bases or by contacting them with alkaline earth zeolites.  The organic acid precipitated with the phosphates may be restored to the treated juices.  The pulp is preferably separated from the juice before treatment (1) by bringing the pH to such a value that coagulation occurs, e.g. grape juice is brought to a pH of 8 to 10 by treatment with calcium carbonate; (2) by passing over naturally or artificially - produced mineral colloids such as clays, glauconites, natrolites, zeolites or ochres, e.g. the juice is treated with a mixture of calcium carbonate and ferric tartrate in equi-molecular proportions, calcium tartrate being precipitated and oxide of iron being formed in the colloidal state and coagulating the pulp particles; (3) the fruit juices may be treated with enzymes which digest the pectic substances, or (4) may be subjected to mechanical treatment to clarify them.  The separated pulp may be subjected to preservative treatment, e.g. with enzymes such as pepsin, to solubilize the organic compounds containing phosphorus and nitrogen therein, and washed with water, and then added to the treated juice.  In examples: (1) raspberry juice is treated with a mixture of calcium carbonate and hydrated magnesia, stirred slowly until neutralized, filtered, a further filtration through a base-exchanger to replace undesirable ions such as of potassium or calcium by an indifferent ion such as of sodium being effected if desired.  Citric acid may then be added to restore the acid content of the juice; (2) grape juice is treated with ferric tartrate; (3) tomato juice is treated with pepsin to digest a portion of the matter in suspension, filtered to remove the pulp, and a ferric salt, e.g. the double tartrate of iron and potassium added, a precipitate of ferric phosphate being formed.  The pulp is treated with water slightly acidulated, e.g. with citric acid, and emulsified in the treated juices; (4) the pulp is separated from orange juice, e.g. by defecating, using calcium carbonate and ferric tartrate, the juice after filtration being treated if necessary with ferric hydroxide to precipitate nitrogen and phosphorus.  The pulp is, after enzymatic treatment, washed with water acidulated with citric acid and then with water in which is emulsified oil of orange and is finally emulsified in the treated juice.
