Patent GB-882086-A (GB)
Title: Differential pressure transducer
IPC: G01L9/00
Filed: 1958-05-12
Abstract: 882,086. Pressure transducers; vibration measurement. BORG-WARNER CORPORATION. May 12, 1958 [May 20, 1957], No. 15221/58. Class 40 (1). [Also in Group XIX] A differential pressure transducer comprises a pressure diaphragm flanked by two sealing diaphragms defining a cavity on each side of the pressure diaphragm, a pin attached to each diaphragm by means of a hub separated from the outer portion by a flexible web of reduced thickness so that differential pressure on the sides of the pressure diaphragm causes axial movement of the three hubs and the pin, and a vibrating string attached to the pin and to a framework so that its tension is varied by movement of the pin. Preferably the string is maintained in vibration at its resonant frequency so that measurements of this frequency determine the tension and hence the differential pressure. In Fig. 1 the pressure diaphragm 26 and sealing diaphragms 25, 27 each have webs of reduced thickness 36, 32, 30 respectively, the first named being nearer the centre than the other two. One fluid is admitted via port 40 to a cavity 33 which communicates with a further cavity 34 and urges the pressure diaphragm to the right. The other fluid is admitted at 41 to a cavity 36 and urges the pressure diaphragm to the left. The differential pressure causes the central portion of the diaphragm to move in one direction or the other, and this carries with it a pin 39 and the central portions of the other diaphragms which are rigidly attached to it. A further calibrating diaphragm 24 is constructed similarly to the other three and has its central portion likewise attached to the pin 39. A wire 8 is maintained in tension between the pin 39 and a similar pin 17 at the other end of the unit, and is kept in vibration at its resonant frequency by means described below. The pin 17 is attached to another similar flexible diaphragm 15 which is adjustable by means of a screw 22. This screw carries two nuts of different pitch, one attached to the diaphragm 15 and the other to a further diaphragm 18 fastened to the frame of the unit. Adjustment of the screw 22 thus alters the separation of the diaphragms 15 and 18, and hence the initial tension on the wire. Calibration of the device is effected by altering the thickness of the web portion 38 of the calibrating diaphragm 24. The wire 8 passes through a semi-circular magnet and is kept in vibration by an electronic oscillator shown in Fig. 3. The wire is connected in a Wheatstone bridge with a similar wire 47 which is not in a magnetic field. Any change in the impedance of the wire 8, due to a change in the back E.M.F. induced in it by the magnetic field, alters the signal applied to three cascaded amplifier valves 51, 61, 73. A voltage is fed back from the anode of valve 61 to maintain oscillations in the valve 8, the amplitude being kept constant by an A.G.C. circuit fed from the output of valve 73 by a rectifier bridge 86. The output signal at terminal 83 is fed to a frequency meter 95 to indicate the value of the differential pressure.

Title: Improvements relating to the manufacture of crystalline menthol
IPC: C07C35/12
Filed: 1927-06-08
Abstract: 297,019. Howards & Sons, Ltd., and Blagden, J. W. June 8, 1927. Menthol.-By subjecting synthetic menthol to partial esterification, separating the unesterified from the esterified portion, and saponifying the latter, the parent material is divided into fractions of different melting-point of which one is of higher melting-point than that of the starting material. A similar result is obtained by partially saponifying a menthol ester, separating the liberated menthol from the unsaponified ester, and saponifying the latter. The partial saponification and esterification may be effected in two or more stages, and both may be combined. The process is applicable both to crystalline menthol of melting-point about 34‹ C. and to crude synthetic menthol of lower melting-point; menthol prepared by the hydrogenation of thymol, piperitone and menthone, and particularly that prepared according to Specification 213,991 and 238,314, is specially mentioned. At other stages of the partial saponification or esterification, there may be produced a crystalline menthol of lower melting-point or a liquid menthol, and these may be again treated, together if desired with a further quantity of parent menthol; alternatively, they may be treated by the processes described in the aforementioned Specifications. The esterification may be effected with aliphatic or aromatic acids or anhydrides; when the acid is polybasic, e.g. phthalic acid, either a normal or an acid ester may be formed. The saponification is carried out by treatment with caustic alkali, but in the case of an acid ester steam distillation may also be employed. Examples are given.

Title: Agglomerating process
IPC: A23L1/00
Filed: 1963-04-19
Abstract: Agglomerates of pulverulent material having larger average particle size than the unagglomerated constituent particles and improved blending and mixing properties in aqueous systems, are produced by contacting the particles with a fine spray of a sticky p  cohesive binding liquid and agitating the particles in a gentle manner sufficient to blend the liquid uniformly with them and to roll up the treated particles upon each other into free-flowing, non-sticky aggregates without drying.  Pulverulent materials mentioned: cake mixes containing flour, sugar, shortening and other ingredients; pancake mixes; pastry mixes; confectionery mixes; dry milk solids and powdered beverages.  Preferred binding liquids are melted or normally liquid glyceride shortenings (specified) having a Solids Content Index at 70 DEG F. greater than 5 and concentrated aqueous sugar solutions having a weight ratio of sugar to water of from 1.5 : 1 to 4 : 1.  Also particularly mentioned as binding liquids are: aqueous starch solutions, water-soluble salts of carboxymethyl cellulose, aqueous solutions of dextrose or invert sugar, propylene glycol and glycerol. During the spraying, the particles of pulverulent material may be tumbled in a cylinder mounted on a horizontal axis or gently fluidized.  According to one of several examples a 40 lb. batch of a culinary mix of 3.8% moisture content consisting of 38% by weight of bleached cake flour, 50% sugar (9 parts sucrose to 1 part dextrose) and 12% plastic fatty acid triglyceride shortening derived from soybean oil and emulsified with mono- and diglycerides and glyceryl lactyl stearate, was heated to about 110 DEG F. and was then agglomerated in a slowly rotating horizontal cylindrical chamber 2 feet long, 2 feet in diameter and provided on its inner surface with 4 longitudinal radially disposed baffles, each about 2 inches high. A sticky binding liquid prepared by mixing 3 parts of sucrose with 1 part of water and heating to 180 DEG F, was sprayed through an atomizing nozzle under a pressure of 3,000 p.s.i. for 3 minutes while the cylinder was being rotated at 20 r.p.m.; the agglomerates produced had a moisture content of 4.9% and could be wetted-out in about 30 seconds to give a smooth batter from which, after the addition of leavening, milk solids, sodium chloride and cocoa, a cake was baked.  Other ingredients for the pulverulent material mentioned are dextrose, starch and flavouring materials.

Title: Steroidal hormone intermediates and their preparations
IPC: C07J1/00
Filed: 1942-11-05
Abstract: Androstane compounds are prepared from D 16-20-keto pregnane compounds having no nuclear keto substituents by treatment with an oxime forming reagent followed by subjecting the product to the Beckmann transformation, and hydrolysing the product.  The oxime forming reagent may be either hydroxylamine or an acid addition product thereof, preferably the sulphate.  A dehydrohalogenating agent, such as sodium acetate or pyridine, may be present.  The Beckmann rearrangement may be carried out with any agent known to be suitable for this purpose, such as acidic agents, and agents which are reactive with water to form strong acids.  Agents mentioned include hydrochloric and sulphuric acids, phosphorus pentachloride, thionyl chloride, antimony pentachloride, benzene sulphonyl chloride, benzoyl chloride, benzene sulphonyl bromide, methane sulphonyl chloride, anthraquinone sulphonyl chloride, and p-nitrobenzene sulphonyl chloride.  The presence of a diluent such as acetic acid dioxane, ether, benzene pyridine dimethylaniline, tributylamine, N-ethylmorpholine or quinoline is usually desirable, the preferred solvent being a tertiary amine.  Starting materials mentioned include D 4,16 - pregnadienone - 20, D 5,6 - pregnadienone - 20, D 5,16 - pregnadienol - 3 (b ) - one - 20 - acetate, 3 - chloro - D 5,16-pregnadienone-20, D 16-allo-pregnenediol-3(b ) : 6 - one - 20 - diacetate, D 4,16 - pregnenediol-3 : 6-one-20-diacetate, D 5,6-pregnenediol-3 : 4-one - 20 - dibenzoate.  In examples: (1) D 16-pregnenol - 3 - (b ) - one - 20 acetate in alcoholic solution is treated with an aqueous solution of hydroxylamine hydrochloride and sodium acetate at room temperature to give D 16-pregnenol-3(b )-one-20-acetate oxime, which is treated with p-toluene sulphonyl chloride in pyridine solution, and then hydrolysed with 10 per cent aqueous sulphuric acid to form etio-cholanol-3(b )-one-17-acetate. (2) D 5,16-pregnadienol-3(b )-one-20-acetate in alcohol is treated with an aqueous solution of sodium acetate and hydroxylamine as in example 1 to form D 5,16-pregnadienol-3(b )-one-20-acetate oxime which is p  treated with p-toluenesulphonyl chloride in pyridine solution and then hydrolysed as before to give D 5-etio-cholenol-3(b )-one-17-acetate.  (3) D 5,16-pregnadienol-3(b )-one-20-acetate is allowed to stand four days in pyridine solution with hydroxylamine hydrochloride when benzenesulphonyl chloride is added and then hydrolysed as before to D 5-etio-cholenol - 3(b ) - one - 17 - acetate. (4) D 5,16-pregnadienol - 3(b ) - one - 20 - acetate oxime is treated with phosphorus pentachloride in dioxane solution, and then hydrolysed with dilute hydrochloric acid to give dehydroisoandrosterone.  Specification 552,047 is referred to.

Abstract: 575,003. Toothed gearing; gear cutting. MERRITT, H. E. Sept. 24, 1943, No. 15666. Convention date, Sept. 28, 1942. [Class 80 (i)] [Also in Group XXII] Gear teeth, particularly for clockwork and instruments, are derived from a basic rack, the faces and flanks of the tooth profiles of which consist of similar curves a, b composed of arcs of circles, the radii a<3>, b<1> of which are approximately equal to the pitch and which are arranged in alternate reversion, the centres of curvature a<2>, b<2> of the reversed arcs forming one side of a tooth being so positioned that the arcs osculate at the point of their intersection with the pitch line c and the pressure angle d is approximately 10 degrees. The radius of the arc a may differ slightly from that of the arc b to provide a small amount of tip relief. Gears with the proportions described and with an addendum approximately 0.8 times the module will be interchangeable. To give the larger clearance usually employed, the teeth of the cutter are thicker than one-half of the pitch. The teeth may be cut by a hob formed by a tool, either flank of which consists of two circular arcs having opposite and usually (but not necessarily) equal radii of curvature. The flanks of the forming tool are finished by a grinding wheel, the profile of which is trimmed by mechanical means to a convex arc which will produce the concave portion of the profile of the tool corresponding to the arc b. The convex portion of the tool corresponding to the arc a, the grinding wheel and supports are rotatably mounted about an axis through the centre of curvature of the convex portion of the tool. The wheel support is given a gradual angular motion about its axis of rotation. For a tool of rectilinear form, the cutter will be reciprocated relatively to the wheel. The wheel may be replaced by a cutting tool. Specification 274,667, [Class 80 (i)], is referred to.

Abstract: 1,139,774. Drying webs of knitted fabric. R. KAUSCHKA. 7 April, 1966 [7 April, 1965], No. 15717/66. Heading F4G. Apparatus for drying webs of knitted fabric or similar materials whose edges tend to curl during drying, e.g. after passing through a printing machine 3, comprises supports 7, 8 which are convexly curved in the direction of movement of the material thereover and over which the web is slidably conveyed whilst being dried. The web may slide directly over the supports or it may be associated with an endless backing web 6 adapted to slide thereover. Driven rollers 10 pull the web and material over the support surfaces, which thereafter separate, the web returning to the support 7 and the material passing over a pivoted support 11 to a winding reel 12. A driven roller 9 is mounted at the junction of supports 7, 8 to reduce friction. Hot air is projected on to the web for passage co- and countercurrent to the material from upper passages 21 having exits 15, 16 to suction exhaust ports 17, 18, 19. In a modification, Fig. 2, (not shown), four convexly curved supports are arranged in spiral form with rollers mounted between each pair of adjacent supports to accommodate sudden changes in direction of the web and to reduce friction.
