Filed: 1942-12-04
Abstract: 559,341. Jointing by stamping. AUTOMOTIVE PRODUCTS CO., Ltd., and TRINDALL, V. G. Dec. 4, 1942, No. 17305. [Class 83 (iv)] A metal sleeve is contracted round a hose &c. by first compressing the sleeve along one diameter to its final size and thus compressing along a diameter at right-angles to the first at the same time maintaining along the first diameter. As applied to securing an end connection 32, Fig. 7, in a high-pressure flexible hose 33 a groove 37 is formed in a sleeve 35 placed over the hose to compress it on the internal spigot 34. The compression is effected by a two part die 10, 11, Fig. 4, formed with projections 17, 18 to produce the groove. The part 11 is fitted with pins 21, 22 in the plane of the projections 17, 18 the distance between the pins at their full diameter being the diameter at the bottom of the groove 37. The pins are flattened at 28, 29 the distance between the flats being equal to the original diameter of the sleeve which is placed in the die as shown in Fig. 4 and rests on inclined portions 30, 31 which as the upper die part descends compress the sleeve to oval form, Fig. 5. On further closure of the die parts the full diameter parts of the pins maintain the original compression whilst the parts 17, 18 apply compression at right-angles and bring the groove 37 to circular form. A number of axially spaced grooves such as 37 may be formed or the sleeve may be compressed over its full width. The two parts of the die may be pivotally connected the pins 21, 22 then being curved to suit the angular movement of the parts. The initial compression may be effected by auxiliary jaws.

Abstract: 779,527. Dielectric heating. VICARS, Ltd.. T. & T., and NAYLOR, J. F. June 3. 1955 [June 12, 1954], No. 17334/54. Class39(3) [Also in Group XII]  Dough products are conveyed through a baking oven comprising three zones 10, 11, 12 of substantially equal length, the first and third zones 10, 12 each having at least one heating unit for providing top and bottom heat, e.g. by radiation or forced convection or both, and the second zone having a baking unit producing a high frequency field, all the baking and heating units being indepently controlled and each being variable within itself. The products are carried on an endless conveyer 13, e.g. a steel band or woven wire mesh. In zone 10 combustion gases are fed from gas burners 14 mounted in supply ducts 15 through dampers 16 and fans 17 into ducts 18 from which they pass through perforations into the oven chamber. The gases return through ducts 20, manifolds 21 and damper 22 where a proportion of the gas, predetermined according to dryness required in the oven, is spilled along ducts 23 to a power driven extraction fan 24 and the remainder is returned along ducts 25 to the burners 14. Grids 26 are provided in zone 11 connected by leads 28 to a high frequency generator. As shown a forced convection system similar to that in zone 10 is provided in addition to the high frequency heating. Alternatively the high frequency heating can be supplemented by infra-red heating. Heating in zone 12 is similar to that in zone 10. In a modification, Fig. 7, the perforations in the upper and lower ducts 18b of zone 10 or zone 12 may be closed by pivoted deflector plates 30. Pivoted dampers 31, 32 are provided which may close the ends of return manifolds 33 which connect ducts 18b and spill ducts 23. Thus, when the perforations in ducts 18b are closed and manifolds 33 are open, the combustion gases pass along ducts 18b and return along manifolds 33 so that heating takes place, by radiation alone. By opening the plates 30 and closing the dampers 31, 32 the original circulation is restored. Specifications 713,271 and 755.237 [both in Group XII] are referred to.

Abstract: A methyl silicone gum is prepared by hydrolyzing a mixture of mono-, di- and trimethyl silanes and treating the oily product with a polymerization catalyst which is (a) ferric chloride, or (b) ferric oxide and aluminium chloride, or (c) sulphuric acid. Preferably the average methyl to silicon ratio of the hydrolysis mixture is 1.98 to 2.0.  The mixture should contain less than 5 mol. per cent of monomethyl silane and 0.4-0.95 mols. of trimethyl silane per mol. of monomethyl silane.  Elastomers may be prepared by compounding the gums with catalysts and fillers as in Specification 594,481.  The products are soft, with low permanent set at high temperatures, and are particularly useful for gaskets. In the examples, (1) a mixture of 98.081 mol. per cent dimethyldichlorosilane, 0.984 per cent methyl trichlorosilane, and 0.934 per cent trimethylchlorosilane was hydrolysed and the oil polymerized to a soft elastic gum by heating with ferric chloride hexahydrate.  The gum was compounded with lead oxide, titanium dioxide and benzoyl peroxide, and the product moulded and cured.  Examples (2) and (3) use different proportions of the various methyl silanes; example (4) employs more ferric chloride hexahydrate.  Example (5) employs an oil prepared by blending the products of hydrolysis of methyltrichlorosilane and dimethyldichlorosilane, with the product of hydrolysis of dimethyldichloroand trimethylchlorosilane.  Curing may be performed in two stages, with a second addition of benzoyl peroxide. Specification 618,452 also is referred to.

Title: Improvements in or relating to the treatment of cereals and other starch containing food substances
IPC: A23L7/10
Filed: 1930-06-06
Abstract: 356,794. Roller grinding or crushing mills. KELSEY, T. S., 5, Old Palace Lane, Richmond, Surrey. June 6, 1930, No. 17585. [Class 59.] A process for treating cereals and other starchcontaining food substances comprises subjecting the flour obtained therefrom to the action of steam to soften the starch cells and immediately thereafter subjecting it to an energetic grinding action for the purpose of bursting or disrupting said starch cells. Flour in the form of a thin sheet or film is subjected to the action of steam at a temperature of about 200‹ F. and at a pressure of about 60 to 80 1bs. per square inch, just prior to its entry between the nip of a pair of rollers one of which is rotated at about three times the speed of the other, after passing between which it is brought into contact with a stream of humidified air, sifted and fed to an expansion chamber where excess moisture is separated therefrom. Apparatus for carrying out this process comprises a feed channel 1 whence flour is fed by a platform 2 reciprocated by an eccentric 3 to a distributer 4 having ribs 9 on its upper surface and reciprocated by an eccentric 10 on a shaft 11. Flour in the form of a thin sheet falls from the distributer 4 through steam jets issuing from perforated steam pipes 12, 13 substantially parallel to the sheet of flour, on to grinding rollers 5, 6 after passing between which it passes into the hopper 14, and is forced through a screen 16 by a rotary spiral brush 17 into an expansion chamber 18 where excess moisture is removed by the fan 20, the moisture passing by a conduit 19 into a cyclone separator 21 where any flour sucked through the conduit 19 by the fan 20 is separated and collected for use. Dampers 22 operated by levers 23 control the effect of the suction fan 20 on the upper part of the apparatus. The grinding rollers are hollow with a smooth outer surface, their temperature being controlled by the water and steam circulating system shown in Fig. 3, cold water entering along the pipe 24 and steam along the pipe 25 cocks 28, 29 and control valves being provided as shown. A pressure reducing valve on the steam pipe line and means to prevent the supply of more than a predetermined quantity of steam may be provided. Rollers, eccentrics, and brush 17 are driven from the same prime mover. The steam supply is automatically cut off when the rollers cease to rotate by the device shown in Fig. 5, in which a pair of centrifugal elements 32 joined by a spring 35 are pivotally mounted on members 34 attached to the shaft 11, fingers 36 on the elements 32 co-operating with a collar 37 and a sleeve 39 slidably mounted on the shaft, which sleeve is attached to the spindle 40 of a valve 41 in the steam pipe, the valve 41 being spring controlled at 42. The reciprocating distributer 4 may be replaced by slides. Scrapers 45 are provided on the rollers.

Abstract: 777,402. Geophysical surveying. CANADIAN AIRBORNE GEOPHYSICS, Ltd. June 20, 1955 [July 30, 1954], No. 17807/55. Class 37. In geophysical surveying apparatus of the type in which an alternating field produced by a coil 2 induces in ore deposits eddy currents the effect of which is picked up by a coil 4, the direct effect of coil 2 on coil 4 is neutralized by means of a circuit 3, 5. As shown, coil 4 is tuned and the signal picked up is amplified and resolved in known manner into its in-phase and quadrature components which are separately recorded. Alternatively the pick-up may be measured by a null method with the aid of calibrated attenuators for the respective components. When coils 2, 3 and 4 are carried in a bird towed by an aircraft, errors due to changes in the relative position of the coils in flight are minimized by securing the coils to an elongated support 13 which is attached to the bird at two points 14, 15 between the coils. By this means the tendency of the support 13 to bend in response to accelerators applied by the towing cable is counteracted by the inertia of the coils &c. at its ends.
