Abstract: 431,505. Wrapping-machines. AMERICAN MACHINE & FOUNDRY CO., 511, 5th Avenue, New York, U.S.A. Dec. 17, 1934, No. 36191. Convention date, May 31. [Class 94 (i)] A wrapper after having been partially wrapped about an article, e.g. a loaf, is engaged between a pair of rollers which normally exert a moderate tension thereon, and means are provided by which one of the rollers may be driven in either direction to increase or reduce the tension in order to produce a more tightly or a more loosely wrapped package. A loaf is pushed from an inclined runway on to a lifter table 27 carrying with it the hanging end of the web W, which is thereby folded about three sides of the loaf. As the lifter table 27 moves to its upper position, more wrapping material is pulled off the roll, and at the same time the frame 23 is moved so that the roller 19 which it carries presses the web against the roller 26. The roller 19 is coupled by a sprocket chain 17 and sprocket 16 to a slidable shaft 15 which may occupy any one of three positions. In the central position the shaft 15 is undriven. In the inner position it is coupled directly to a shaft 13 driven by the conveyer chain 11 of the machine. In the outer position it is coupled to a bevel gear 22 which is mounted thereon and is driven from the shaft 13 in the reverse direction through bevel gears 20, 21. The web is cut by a knife 29 mounted on the frame 23 below the roller 19, and the partially wrapped loaf is advanced on to a table 28 for the completion of the folding operations.

Abstract: 1,127,817. N - Hydroxyaryl - terephthalamic acids and esters. RHONE POULENC S.A. 12 Aug., 1966 [12 Aug., 1965; 14 June, 1966], No. 36275/66. Heading C2C. [Also in Division C3] The invention comprises N-hydroxyarylterephthalamic acids and esters of the general formula in which X is HO-Ar in which Ar is an arylene radical which may be substituted by one or more hydrocarbon radicals, Y is HO-Ar or, when X is other than p-hydroxyphenyl, is hydrogen or a hydrocarbon radical, and R represents hydrogen or alkyl. These compounds may be prepared by reacting an aminophenol of formula with an acid chloride of formula in which R is alkyl and, if desired, hydrolysing the ester so formed to give the free acid. Alternatively the esters may be made by the reaction of an aminophenol with a mixed terephthalic ester of a higher fatty alcohol and a lower alcohol such as methanol or ethanol. The N-hydroxyarylterephthalamates of higher alcohols may also be prepared by transesterification of the ester of a lower alcohol with a long-chain alcohol. In the examples: (a) terephthaloyl chloride is reacted with octadecanol to give dioctadecyl terephthalate which is reacted with tert.-butyl alcohol to give the mixed ester; the mixed ester is reacted with thionyl chloride to give 4-octadecyloxycarbonyl-benzoyl chloride which is then reacted with 4-amino-2,6-di-tbutylphenol to give octadecyl-N-(4-hydroxy- 3,5 - di - t - butylphenyl) terephthalamate; (b) 4 - octadecyloxycarbonyl - benzoyl chloride is reacted with o-amino phenol to give octadecyl- N - (2 - hydroxyphenyl) terephthalamate; (c) 4 - octadecyloxycarbonyl - benzoyl chloride is reacted with 2-amino-4-t-butylphenol to give octadecyl - N - (2 - hydroxy - 5 - t - butylphenylterephthalamate; (d) 4 - octadecyloxycarbonyl-benzoyl chloride is reacted with bis(4- hydroxy - 3,5 - di - t - butylphenyl) amine to give octadecyl N,N - bis(4 - hydroxy - 3,5 - butylphenyl)terephthalamate; and (e) 4-octadecyloxycarbonyl-benzoyl chloride is reacted with 4 - amino - 2 - hydroxy toluene to give N - (3 - hydroxy - 4 - methylphenyl) terephthalamate.

Title: Improvements relating to compositions for sealing, coating and lubricating metallic and other surfaces
IPC: C10M101/04
Filed: 1946-12-12
Abstract: Modified fatty oil compositions suitable for sealing metallic or other surfaces (see Group V), are manufactured by treating a vegetable or animal oil (or a mixture of such oils) to thicken it, and adding to the thickened oil an oxidation and polymerization inhibitor and a vaporizable thinner, i.e. a solvent having a final boiling point not exceeding 250 DEG  C.  The oil may be (preferably) soya bean oil, castor oil, or a mixture of castor oil and another vegetable oil such as olive oil, linseed oil or cottonseed oil, or a fish oil such as menhaden oil.  The oil may be thickened by air blowing at 200 DEG  C. until it has acquired the consistency of a " heavy " oil, grease or gum, and the oxidation inhibitor used may be thymol, eugenol, iso-eugenol, iodine, phenyl-alpha-naphthylamine, phenyl-hydroquinone, abietic acid or oleic acid.  The heating of the oil is discontinued when it has reached the desired consistency and first the inhibitor and then the thinner added.  When the oil is castor oil and the composition is to be used at or near room temperature, ethyl alcohol or carbon tetrachloride is used as a thinner.  A filler or loading material such as short asbestos fibre, ground mica, wood pulp, stone or marble dust, infusioral earth, ground cork, cork dust, graphite, or a metallic oxide may be incorporated in the composition.  The oil may be thickened by " boiling " without air blowing and the boiling may be conducted under reduced pressure in a vessel fitted with a reflux condenser.  In an example, half to one per cent by weight of phenyl-alpha-naphthylamine and twenty to thirty per cent of filler (based on the weight of the original oil) are used in the composition.  Specification 452,536 is referred to.ALSO:Non-setting compositions for sealing and coating gaskets, pipe threads, pipe unions, box connections and other metallic joint surfaces, &c., comprise a thickened fatty oil (or oils), and oxidation inhibitor and a vaporizable thinner (see Group III). The oil may be castor oil and the thinner may in this case be ethyl alcohol or carbon tetrachloride.  A filler such as short asbestos fibre may also be present.  The function of the thinner is to reduce the initial viscosity of the composition sufficiently to enable it to be applied to fragile paper gaskets, the thinner being subsequently removed by evaporation at room or higher temperatures. The function of the inhibitor is to minimise further oxidation and for polymerisation of the oil after manufacture of the composition and thus prevent hardening of the composition after removal of the solvent.  Specification 452,536 is referred to.

Title: Improvements in or relating to passive elements for modifying the phase-front of electromagnetic waves
IPC: H01Q3/12
Filed: 1955-12-23
Abstract: 817,170. Radio directive systems. GENERAL ELECTRIC CO. Ltd., and CORNBLEET, S. Nov. 30, 1956 [Dec. 23, 1955], No. 37006/55. Drawings to Specification. Class 40 (7). A reflector or lens for electromagnetic waves consists of either a cellular metal structure or a solid dielectric body and is formed so as to give the reflected or transmitted wave front a given shape. The necessary phase adjustment is effected within the structure and the functions expressing the shape of the structure are derived by considering the phase changes along three separate paths symmetrical about the axis of the structure. The device will focus a plane-fronted wave, incident upon it, to a point lying on a given surface, at a position on the surface depending upon the angle between the incident ray and the axis of the device. Similarly, a radiator, placed on the given surface, will cause a plane fronted. wave to be produced at the device at an angle to the axis of the device depending upon the position of the radiator on the surface. The cellular structure may have cells with either different cross-sections and identical lengths or different lengths and identical cross-sections, also, the cells may be all of the same size and filled with different dielectrics. In the solid dielectric embodiment the front and back surfaces are shaped so as to provide different path lengths for the radiation passing through the body.

Title: Improvements in or relating to electrical pulse shaping networks
IPC: H03K5/06
Filed: 1954-12-22
Abstract: 770,879. Pulse-shaping networks. INDJOUDJIAN, M. D. Dec. 22, 1954 [Dec. 22, 1953; March 3, 1954], No. 37074/54. Drawings to Specification. Class 40 (8). A pulse-shaping ladder network having input and output resistances R 1 , R 2  comprises a total number n of series inductive and shunt capacitative elements whose values are such that for any frequency f = #/ 2 # the transfer function of the network is equal to (1 + p#n)<SP>n</SP> where p = j## and # is an arbitrary time unit. The transfer function of the network is defined by the expression where Ee<SP>pt</SP> is the E.M.F. at the input and Ue<SP>pt</SP> is the output voltage, E and U being complex numbers. The amplitude response function of the network can be shown to approximate to a Gaussian curve under both sinusoidal and transient conditions even for low values of u. Thus a short pulse applied at the input to the network produces at the output a bell-shaped pulse. The network differs from the usual type of ladder network in that it is a non-iterative structure, i.e. the sections are not identical. The values of the elements may be calculated by multiplying the values of those in the delay network of Specification 770,878 by #n. The Specification gives tables of values as general formulae for networks in which R 2 = #. Numerical values ranging from n = 1 to n = I and n = 1 to n = 6 are given respectively for networks in which R 2  = oo and R 1  = R 2  = 1. The values given are impedances or admittances of elements at a frequency # 0  = 1/ #  the unit of impedance being R 1 . For even values of n the network comprises n/ 2  L-type sections and for odd values of n the network comprises n-1/2 L-sections with an additional inductive or capacitative element. Where R 2  = oo the values are obtained from the ratio: (where #(p) is the transfer function) by developing into a continuous fraction, on the one hand, this ratio and, on the other hand, the input impedance of the network referred to unit angular frequency # 0  = <SP>1</SP>/ #  and to unit resistance R 1  and identifying like terms in the two developments. Similar methods are given for networks in which R 1  and R 2  are arbitrary. In each case the input impedance is equated to a polynomial formed from the expression for #(p). The Specification gives rules for forming polynomials to determine values for even n and odd n and for networks terminating in inductive and capacitative elements.

Title: Improvements in or relating to the production of artificial sausage casings
Inventor: FOX BERNARD VICTOR
IPC: A22C13/00
Filed: 1954-12-22
Abstract: Alginate sausage casings showing an increased tendency to shrink transversely when dried, e.g. by frying, are made continuously by extruding a viscous aqueous solution of a water-soluble alginate through an annular nozzle into a coagulating bath comprising an aqueous solution of a salt, preferably of calcium, capable of forming by reaction with the water-soluble alginate a water-insoluble metal alginate, retaining the gel tubular body so produced in the bath until it is at least partially set and stretching the body in the direction parallel to its longitudinal axis by at least 5 per cent of its original length, in the absence of fluid pressure within the body sufficient to stretch it transversly.  The alginate sausage casing may be composed of alginic acid and/or a softening agent in addition to the water-insoluble metal alginate.  The alginate solution may contain 3-7 per cent by weight of the alginate, e.g. sodium alginate. The salt in the coagulating bath may be calcium chloride or acetate or aluminium sulphate, and the bath may also contain a small proportion of an acid, e.g. 0.01-5 per cent by weight of hydrochloric acid, and 0.5-8 per cent of sodium chloride.  The partially set alginate casing may be stretched by as much as 100 per cent of its original length, but 20-50 per cent is preferred.  In the example, a 4 per cent de-aerated filtered aqueous solution of a commercial sodium alginate is extruded through an annular orifice into an aqueous coagulating bath at 18 DEG  C. containing 10 per cent of calcium chloride, 0.1 per cent of hydrochloric acid and 2.5 per cent of sodium chloride.  The partially set self-sustaining gel tubular body thereby formed is longitudinally stretched by 25 per cent by passing it over three sets of fixed cylindrical glass rods submerged in the bath, and then stored until completely set in a second aqueous bath at 18 DEG  C. containing 15 per cent of calcium chloride and 1 per cent of sodium chloride.  The casing is finally washed with water at 15 DEG  C., dried to a water-content of 7 per cent by weight by passage over and in contact with drying rollers heated to 70-80 DEG C., passed through a water bath at 15 DEG  C., and wound up on a reel.  Specification 711,437 is referred to.
