Patent GB-815353-A (GB)
Title: Preparation of peracetic acid
IPC: C07C409/26
Filed: 1957-04-26
Abstract: Peracetic acid is prepared by oxidizing liquid acetaldehyde with oxygen-containing gas in the presence of a chloride or bromide of copper, a chloride or bromide of cobalt, or cupric ammonium chloride. The oxygen-containing gas may be pure oxygen or a gas containing oxygen in dilute form, e.g. air or oxygen-enriched air.  The preferred temperature range is 0-50 DEG  C., most preferably 5-40 DEG C., although temperatures as high as e.g. 60 DEG  C. or as low as e.g. - 30 DEG  C. may be used.  It is advantageous to use an organic liquid diluent such as a volatile ester, especially methyl or ethyl acetate, acetone and acetic acid.  The latter is formed as a by-product in the reaction and is a particularly advantageous diluent.  The proportion of diluent may be from 0-90 per cent by weight of the reaction mixture.  The catalyst is usually present in the proportion of 0.002-0.20 per cent by weight of the reaction mixture.  The catalyst may be formed in situ by introducing a soluble salt of copper or cobalt before starting the reaction and then introducing dry gaseous hydrogen chloride or hydrogen bromide along with the oxygen-containing gas.  A refined product comprising a solution of peracetic acid in acetic acid, the peracetic acid constituting at least about 5 per cent by weight of the acetic acid, may be obtained from the reaction mixture by distillation at a pressure not greater than about 40 mm. Hg.  Concentrated peracetic acid can be separated from this product e.g. by low-temperature distillation at pressures of the order of 1-10 mm. mercury.  In examples, peracetic acid is obtained from acetaldehyde in both batchwise and continuous processes by oxidation with oxygen or oxygen/nitrogen mixture using cobaltous chloride hexahydrate or cupric bromide as catalyst and ethyl acetate as diluent.

Title: Improvements relating to flowmeters
IPC: G01F1/684
Filed: 1948-05-14
Abstract: 651,152. Electric indicating systems. LOVE, J. A. May 14, 1948, No. 13324. [Class 40 (i)] In an electric flowmeter fluid passes through a tubular conduit containing a heater coil H intermediately of two double balanced temperature-sensitive resistance coils R1, R2, all disposed in recesses in a heat insulating lining to leave a central bore. The halves of the resistance coils are connected as opposite arms of a D.C. Wheatstone bridge whose unbalance voltage energizes the control winding W of a saturable A.C. fed transformer T1 having its secondary differentially connected with the secondary of a similar transformer T2 without a control winding, to serially energize the heater coil, a rectifier meter N, and an integrating meter I. The bridge is balanced when the downstream resistance, to which the heater is nearer, is at a slightly higher temperature than the upstream resistance, so that at zero flow the unbalance voltage regulates the heater current to a value just sufficient to maintain the system in equilibrium. Increased flow reduces the downstream resistance temperature and the increased unbalance voltage adjusts the heater current to a correspondingly higher value, at which equilibrium is again restored, and the meter N indicates the rate of flow, while the integrating meter I measures the total flow. The rate of flow meter may be resistance shunted to vary the range or rectifier shunted to give a logarithmic response.

Title: Improvements in electronic calculators
Inventor: WEIGHTON DONALD
IPC: G06F3/09
Filed: 1959-04-20
Abstract: 892,320. Digital electric calculators. PYE Ltd. April 19, 1960 [April 20, 1959], No. 13403/59. Class 106 (1). A high-speed electonric calculator serves a number of data stores each of which is associated with a keyboard. When a typewriter 4 has completed entry of data into a store 2 the store signals a selector switch control circuit 5 which connects the data store to the central arithmetical unit 1 over a circuit shown schematically as a selector switch 3. Selector switch control circuit, Fig. 2. A ring counter VIA-VID normally steps continuously. Associated with each tube is a circuit V2-V5 corresponding to one of the data stores. Initially, V3 and V5 in each circuit are conducting. Call tube V2 strikes at a signal on terminal T1 that the related data store requires connection to the arithmetic unit. V3 is consequently extinguished. When the ring counter reaches the associated tube, say V1B, it stops and causes gate tube V4 to conduct, so extinguishing V5. Gate tube V4 signals over terminal T2 to connect the data store to the arithmetic unit. At the end of the computation a signal at T3 restores V3, V5 and the ring counter resumes stepping.

Title: Improvements in or relating to manufacture of dehydrated potatoes
IPC: A23L19/15
Filed: 1962-04-06
Abstract: 1,009,936. Dehydrated potatoes. R. A. S. TEMPLETON. April 2, 1963 [April 6, 1962], No. 13433/62. Heading A2D. In the production of a dehydrated mashed potato product, the potatoes are initially pre-cooked in an unpeeled condition for 10-60 minutes in a dilute alkali solution having a strength of less than 5% to effect simultaneous precooking of the potato flesh and softening of the potato skin to ease its subsequent removal. The unpeeled potaoes may be treated in a 1-3% caustic soda solution at a temperature of 140- 180F. for 20-40 minutes, skin removal may then be effected by the application of strong sprays of cooling water accompanied by simultaneous agitation to commence the breaking up of the alkali-softened skins, and cooking of the cooled peeled potaoes is completed by immersion in water at a temperature slightly below boiling point, such as 205-210F. Alternatively, the heating of the potatoes for final cooking is obtained by immersing them in liquid at a temperature not more than fifty-five degrees F. above the surface temperature of the cooled potatoes and heating them slowly to boiling point, e.g. at a rate of about 5F. per minute; in this case the peeling stage is effected by means of warm or hot water jets between precooking and final cooking, or skin removal takes place after completion of the cooking. The potatoes, after precooking in the dilute alkali solution, are preferably immersed in, or sprayed with, a dilute solution of a weak acid, such as a 1% aqueous solution of citric acid, to neutralise alkali on the skins of the potatoes. After completion of the cooking, the potatoes may be dehydrated to flakes, granules, discs or shreds. Specifications 767,903; 773,361; 791,193 and 884,267 are referred to.

Title: Improvements in halogenated synthetic polymers
IPC: C08C19/14
Filed: 1957-05-01
Abstract: A thermoplastic halogenated polymer is made by dissolving both a rubbery aliphatic conjugated diene polymer or copolymer and a liquid aliphatic conjugated diene polymer or copolymer in an organic solvent and halogenating the polymers.  The diene preferably contains 4-12 carbon atoms and may be 1.3-butadiene, isoprene, piperylene, 2-methylpentadiene, 2.3 - dimethyl - 1.3 - butadiene or chloroprene and it may be copolymerized with styrene, alpha - methylstyrene, alkyl-, alkoxy- or halogeno-styrenes, or esters of acrylic or methacrylic acids. The solvent may be carbon tetrachloride, chloroform, ethylene dichloride, tetra-chloroethane, chlorobenzene or benzene.  The halogenating agent may be elemental halogen or a compound yielding it.  When halogenation has proceeded to the point of saturation of the double bonds, further halogenation may be effected in presence of a chlorination promoter, e.g. iodine, benzoyl peroxide, stannic chloride, antimony oxychloride, or ultra-violet light.  The halogenated product may be separated from the reaction mixture by pouring the reaction mixture into water or an alcohol. The rubbery diene polymer may be made by emulsion polymerization of a mixture of (Example I) butadiene, water, potassium rosin salt, potassium chloride, potassium hydroxide, ferrous sulphate, the tetra-sodium salt of ethylene diamine tetra-acetic acid, sodium formaldehyde sulphoxylate, diisopropylbenzene hydroperoxide and tertiary dodecyl mercaptan, short-stopping the reaction with di-tert-butylhydroquinone and adding tris-nonylphenyl sulphite as anti-oxidant.  (Example 6) butadiene, styrene, water, potassium rosin soap, potassium hydroxide (to give a pH of 10.8\sB0.3), potassium pyrophosphate, ferrous sulphate, potassium sulphite, trisodium phosphate, cumene hydroperoxide, a blend of C12, C14 and C16 mercaptans and the sodium salt of a condensed aryl sulphonic acid, short stopping the reaction with hydroquinone and hydrogen peroxide and adding a diphenylamine/acetone condensate as anti-oxidant.  The liquid butadiene polymer may be made (Ex. 1) by heating under pressure butadiene dissolved in heptane in presence of sodium.  (Ex. VII) by emulsion polymerization of a mixture of butadiene, water, methanol rinse, potassium soap, potassium hydroxide, potassium chloride, potassium chloride, the sodium salt of condensed alkyl aryl sulphonic acid, K4P2O7, ferrous sulphate, oxidized alkyl aryl sodium sulphonate and tert.-dodecyl mercaptan.  The products, depending on their halogen content are soluble in benzene, toluene, acetone and carbon tetrachloride, are compatible with alkyd and phenolic resins, may be sulphur-vulcanized and are useful in coating compositions, adhesives and cements, in wirecoating and textile-coating compositions and in the manufacture of tubing and moulded products.

In a device for measuring minute displacements, two gratings 12,14 bearing similar arrays of fine parallel spaced lines thereon, are mounted in parallel planes and with the line array on one grating at a small angle to the other, by "T"- shaped members 11,13 the ends of which pass through apertures 1a, 2a, 1b, 2b in supports 1, 2 connected by flexing springs 3, 4. The members 11,13 are fulcrummed on knife edges connected to supports 1, 2 by spring members 6, 7, 9, 10. Knife edges 5, 8 are connected to reference points whose relative displacement is to be measured, e.g. two points on a structure if the device is to be used as a strain gauge, and relative movement of knife edges 5, 8 causes rotation of members 11, 13 either in the same direction, see Fig. 2, or in opposite directions, see Fig. 1. In the embodiment of Fig.1 this rotation increases the angle between the line arrays and thus alters the spacing between the interference fringes formed by the gratings. In the embodiment of Fig. 2 the net effect of rotating members 11, 13 is a parallel relative displacement between the line arrays thus causing a bodily shift of the fringe lines observed. The supports 1, 2 may be made of a material having a low thermal expansion coefficient and micrometer means may be provided to adjust the initial position of the gratings. The movement of the fringes can be recorded using a camera.
