Title: A readily hydratable animal food and method for the preparation thereof
Inventor: BURGESS HOVEY MANN
IPC: A23K1/16
Filed: 1961-05-01
Abstract: Animal food, for dogs particularly, which is readily hydratable on adding aqueous liquid to form a gravy and not lose its particulate character comprises particles of a gelatinized expanded farinaceous material, a layer of fat on the particles and, in or on the fat, a dry gravy-forming agent exemplified by gum guar, cornflour, pregelatinized starch with carboxymethyl cellulose, pre-cooked potato flour and an alginate.  In making the food, the farinaceous material is moistened, the starch granules are swollen by heating and gelatinization completed at above 212 DEG  F. underpressure; the gelatinized material is then extruded from the high pressure zone to a low pressure zone to expand and dry it, and the expanded product is coated with the fat and the gravy-forming agent.  The farinaceous materials are of grains such as maize, wheat, barley and oats and of grain drivatives such as hominy and wheat flour middlings.  The food may contain proteinaceous ingredients such as defatted soy bean meal, wheat germ meal, dried milk, meat meal and fish scrap, flavourings, e.g. liquid meat extract, colourings, fibrous materials, e.g. beet pulp, yeast, vitamins and mineral supplements.  The fat is exemplified by beef tallow.

Title: Improvements in or relating to apparatus for sorting rods or tubes
Inventor: MUSSON ERIC CYRIL
IPC: B07C5/08
Filed: 1956-05-23
Abstract: 827,979. Sorting by gauging. GENERAL ELECTRIC CO. Ltd. May 23, 1957 [May 23, 1956], No. 15968/56. Class 106 (2). [Also in Group XXX] Apparatus for sorting glass tubes 2 into two or more groups depending on their external diameters comprises a conveyer 1, one or more measuring heads 8, 88, each including a movable gauging member 20 biased towards a rest position and arranged to be displaced from that position by tubes whose external diameter exceeds a predetermined value, a transfer arrangement comprising a pair of coaxial discs 35 having slots 36 in their edges into which the tubes 2 are fed from the conveyer 1 and directing means 25, 45 for directing the tubes 2 from the slots 36 into any one of two or more reception channels 22, 23, 24, the directing means 25, 45 being actuated by a memory means 39, 46, responsive to the displacement of the gauging member 20. As shown, tubes 2 on the conveyer 1 pass under three measuring heads. Two of these, 8, are situated above the ends of the tubes, and the third, 88, is situated above the centre of the tubes. The three heads lie in one line perpendicularly to the conveyer, head 88 being shown to the side for simplicity. The measuring head 8 comprises a bell-crank lever 9, one arm of which carries a roller 20, the other of which carries two micro-switches 13, 14 co-operating with fixed contacts which are adjustable by micrometer screws (not shown). When no tubes are passing, the arm 9 is held by spring means so that switch 13 is engaged by its fixed contact. Tubes to be gauged pass over a fixed roller 34 and if too small to release switch 13 are eventually directed into a reject channel 22. This also happens if the tubes are large enough to operate switch 14 as well. If the diameters at both ends lie between these limits, the tubes are directed into one of the channels 23, 24, according to their effect on head 88. The operation of the memory means is as follows. If switch 13 is not released or if switch 14 is actuated, then, after the tube has operated a governor switch 30, a solenoid L1 acts to push in one of a plurality of studs 39 on a wheel 38 moving in unison with the discs 35. At the appropriate time, the selected stud acts against a projection 42 which operates the directing means 25 by the linkwork shown. The stud is returned to its normal position by means of a fixed cam after this operation. Similar studs 46 on the discs 35 are acted on by a solenoid L2 in response to signals from the measuring head 88. Tubes which do not actuate switch 50 fall under gravity to channel 24 and tubes which do actuate this switch are pushed by an ejector arm 45 (operated by the selected stud 46) into channel 23. The operating means for the solenoids L1, L2 may comprise relays set in action by the firing of cold-cathode valves (Fig. 6, not shown). The apparatus may be tested by using tubes with known defects which should cause a lamp 52 to light if switch S4 is closed.

Abstract: 312,330. Geigy Akt.-Ges., J. R. May 24, 1928, [Convention date]. Monoazo dyes; phthalein dyes. - Monoazo phthalein dyes are obtained bv condensing arylazoresorcinols with N-alkylated or N-arylated aminooxybenzoylbenzoic acids or aminooxybenzoylpropionic acids in equimolecular proportions. The products are mordant dyestuffs, those obtained from diazotized o-oxyamines yielding mainly blue to greenish-blue dyeings when aftertreated on the fibre with metal salts; the presence of additiona.l mordant-dyeing groups, such as carboxyl or o-oxycarboxyl groups in the arylazoresorcinol results in dyeings which are red to brown-red on after-chroming. The following examples are specified. (1) A mixture of the monoazo dyestuff 6-methyl-2-aminophenol-4-sulphonic acid # resorcinol with dimethylaminooxybenzoylbenzoic acid is heated with concentra,ted sulphuric acid for 20 hrs. at 70‹ C., and the dyestuff is precipitated by pouring into water; it dyes wool from an acid bath a reddishblue which is rendered a fast blue by aftertreatment; a similar product is obtained when 4-chloro-2-aminophenol-6-sulphonic acid is used as first component. (2) A mixture of the monoazo dyestuff 1:2: 4-aminonaphtholsulphonic acid # resorcinol and diethylaminooxybenzoylbenzoic acid is heated with concentrated sulphuric acid for 4-5 hrs. at 70‹ C., and the product is separated as in (1); it dyes wool from an acid bath a pure greenish-blue which is rendered duller but faster by after-chroming or after-coppering; the corresponding dyestuff obtained when nitro -1:2:4- aminonaphtholsulphonic acid is used as first component yields green dyeings when after-chromed on wool. (3) A mixture of the monoazo dyestuff anthranilic acid # resorcinol and dimethylaminooxy. benzoylbenzoic acid is heated with concentrated sulphuric acid for 24 hrs. at 70‹ C., and the product is separated as in (1); it yields brownred dyeings when after-chromed on wool. The use as first components of aniline and its sulphonic acids, e.g. sulphanilic acid, chloranilinesulphonic acid, naphthylamines or their sulphonic acids, e.g. 1 :5- or 2 : 6-naphthylaminesulphonic acids gives rise to brown to red dyestuffs, valuable mainly as intermediates. Specifications 12181/97 and 10523/11 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of derivatives of resorcinol as coupling components. This subject-matter does not appear in the Specification as accepted.

Abstract: 419,085. Thermostats. SMITHSON, J. G., Oakdale, Alvechurch, Worcestershire. June 6, 1933, Nos. 16186 and 17346. [Class 64 (ii).] A bimetallic strip a is slightly curved in cross section as shown so that it operates with a snap action at a definite temperature. When employed in a switch, it may be heated by passing a current through it, or through a coil around or near it. The strip may also actuate a valve or indicator. In an application to a switch, Fig. 4, the free end of the strip a carries contacts e and is engaged by one of a pair of toggles h. The common joint of the toggles is connected by a link i to one end of a hand lever j. The strip is heated by a coil k. In the closed position shown, the spring l is insufficient to overcome the elasticity of the strip, but when the latter is heated it snaps upward and the toggles pass to the opposite side of their centre line. This prevents re-closing of the switch on cooling except by the hand lever j. The slot in the link i prevents sufficient movement being given to it by the lever when hot, to enable the contacts to be closed.
