Title: Improvements in or relating to food products
IPC: A23J3/22
Filed: 1955-05-03
Abstract: The cohesive, non-homogeneous food product of the parent Specification is modified by the incorporation in the chewy protein gel of a dough prepared by mixing and kneading water and gluten or a gluten-containing material such as wheat or rye flour. The protein gel precursors are exemplified by 20-30 per cent aqueous preparations, of pH 6.5-7, of protein precipitated by hydrochloric acid from water and calcium hydroxide solution extracts of oil-free soya bean meal, and a 35 per cent aqueous preparation, of pH 4.8, of protein precipitated by hydrochloric acid from a sodium hydroxide solution extract of oil-free groundnut meal.  The dough may be of 5 parts of water and 8 parts of bleached wheat flour of 12-14 per cent protein content.  The dough may form 3-30 per cent of the product. The dough may be placed in sheets between thicker layers of the protein gel precursor, such layers being preferably in the form of superposed parallel cylinders, or the dough may be dispersed as small, irregular particles in the protein gel precursor.  During production, coconut oil, a mixture of cottonseed oil, soya bean oil and hydrogenated cottonseed oil stearine or an aqueous p  emulsion of such oils prepared with the aid of sodium caseinate or the mono- and diglycerides of cottonseed oil, locust bean gum, food dye, and flavourings of salt, sugar and essential oils may be incorporated. The product may be sprayed with deodourized, winterized cottonseed oil.  In making products resembling luncheon meat, the preparations are heated in sealed rectangular cans or loaf-shaped moulds; the product may be sliced and the slices vacuum-packed in polythene envelopes for low temperature storage.

[Class 122 (v)] A seal for a dryer or cooler having a rotary annular-walled cylinder 23, 25, and a stationary distributor head 18 for delivering fluid to the rotary cylinder, the head 18 having annular walls 24 and 26 coaxial with the cylinder walls 23 and 25, consists of an annular labyrinth packing carried either by the cylinder or the distributor head and an annular floating sealing means for preventing the escape of fluid between the cylinder and the distributor head. The seal structure consists of a labyrinth seal ring 29 welded to the head 18 and a labyrinth seal band 31 welded to a filler member 32 which is itself welded to the rotatable cylinder. A pair of floating rings 33 and 34 and a keeper band 37 house a packing ring 38 which bears tightly against the labyrinth seal band 31 to prevent leakage of fluid between the ring 38 and the band 31. Between the ring 29 and the floating ring 33, sealing rings 39, secured to the ring 33 by bolts 40, are provided. Driving pins 41, welded to the floating ring 33 and passing through openings in the ring 34, cause the latter to rotate with the cylinder. Spring pressure is provided to ensure that the sealing rings 39 will be forced against the ring 29 and also that the ring 34 will be forced towards its associated floating ring 33 to compress the packing ring 38 against the labyrinth seal band 31. The above description applies to the outer sealing structure. A similar structure is employed for the inner seal.

Title: Improvements in and relating to thermionic valve transmitting circuits for wireless telegraphy and telephony
IPC: H03B5/10
Filed: 1920-05-11
Abstract: 167,584. Macrorie, A. K., and Shearing, G. May 11, 1920. Thermionic oscillation generators. - In a thermionic valve transmitting circuit for wireless telegraphy and telephony in which the coupling is partly direct and partly inductive, a local circuit coupled to the aerial induces in it a current sufficient to produce drying out when its oscillations stop owing to wet conditions. The anode of the main valve V, Fig. 4, is directly connected to the aerial circuit through the condenser P and its grid is coupled through the coil G. A.n oscillating local circuit containing the valve V and tuned to the aerial circuit causes a current to be induced in the aerial to which it is coupled by the transformer D. High-frequency chokes R, R<1> prevent damping of local oscillations when the aerial circuit is earthed owing to dampness. In another arrangement, Fig. 1, the main valves V, V are in parallel and connected in series with local circuit valves V<1>, V<1> which are also in parallel with one another. The part X of the aerial inductance .contains a fine adjustment Y, a variometer portion Z for " calling up," and has coupled with it the coils C, Q, in the grid circuits of the valves V, V<1> respectively, and the transformer coil D in the local circuit.

Patent GB-990496-A (GB)
Title: Hair-treating agent
IPC: C08G59/30
Filed: 1963-04-03
Abstract: Compositions suitable for treating hair comprise an epoxy organo-siloxane of the formula <FORM:0990496/C3/1> in which n has a value between 1.9 and 3 and in which at least one of the individual substituents R is an epoxidized C-Silinked organic radical, the others being methyl radicals which may be replaced to a minor extent (i.e. up to 10%) by hydrogen atoms or by C-Si-linked polyether radicals which may be esterified, the number of epoxide groups <FORM:0990496/C3/2> for every 100 silicon atoms being 1-250, in solution in water or an organic solvent, e.g. ethanol or methylene chloride. The epoxidized organo siloxanes may be prepared by oxidizing alkenyl silicon compounds with peracetic acid to epoxy alkyl silicon compounds or partially substituted siloxanes can be added to means of their HSigroups to the double bonds of oleofinic epoxides, e.g. epoxybutene or allyl glycidyl ether. Alternatively, amino alkyl or polyamino alkyl- or aryl-siloxanes may be reacted with polyepoxides, e.g. butane-1,3-diol diglycidyl ether or 4,41-dihydroxydiphenyl-di-methylmethane -diglycidyl ether, in such proportions that part of the epoxide groups remain unchanged. The optionally esterified polyether radicals may be introduced into the epoxy organo - siloxanes by reacting polyalkylene glycols with some of the epoxide groups of siloxanes rich in epoxide groups, by adding siloxanes with HSigroups on to olefinic polyethers or by reacting polyalkylene glycols with bromomethyl siloxanes in such a way that part of the bromomethyl radicals are initially retained and these are then reacted with amines or polyamines and the amino groups are caused to react with polyepoxides.ALSO:The stability of shape of hair under the influence of moisture, particularly after it has been curled or waved, is improved by treating it with an epoxy organo-siloxane of the formula RnSiO 4-n/2 in which n has a value between 1.9 and 3 and in which at least one of the individual substituents R is an epoxidised C-Si-linked organic radical, the others being methyl radicals which may be replaced to a minor extent, (i.e. up to 10%) by hydrogen atoms or by C-Si-linked polyether radicals which may be esterified, the number of epoxide groups <FORM:0990496/D1-D2/1> for every 100 silicon atoms being 1-250, either alone or in solution in water o an organic solvent, e.g. ethanol or methylene chloride.  Epoxy organo-siloxanes obtained by the reaction of amino alkyl or polyamine alkyl- or aryl-siloxanes with polyepoxides, e.g. butane-1, 3-diol diglycidyl ether or 4, 41-dihydroxydiphenyldimethylmethane-diglycidyl ether, in such proportions that part of the epoxide groups remain unchanged may be used.  Prior to treatment with the epoxy organo-siloxanes the hair may be waved by rolling it upon curlers, treating it with an aqueous solution containing thio-glycollic acid and ethanolamine, rinsing with water and then treating with an aqueous solution of hydrogen peroxide, rinsing and drying.  Specification 956,222 is referred to.
