Title: Improvements in and relating to methods of and means for preparing candies and like articles for wrapping
IPC: A23G7/00
Filed: 1938-11-22
Abstract: 521,523. Packing ; moulding plastic substances. IDEAL WRAPPING MACHINE CO. Nov. 22, 1938, No. 33966. Convention date, Aug. 15. [Class 94 (i)] A method of preparing a group of candies, or like articles, for wrapping into a single package includes the step of squeezing the group to within a predetermined maximum dimension before delivering the group to a wrapping mechanism. The invention may be applied to a machine for taking a number of small rectangular caramels, which have been independently wrapped in another machine, and wrapping the selected group in a sheet of transparent cellulosic material. The wrapped caramels 54 are conveyed to the sizing mechanism by a belt conveyer 44 which is driven intermittently by a Geneva gear. The caramels 54 are carried on edge, and they are prevented from falling forwards, as the conveyer stops and starts, by a number of small rollers 56 which press lightly on their upper ends. The conveyer brings the leading caramel into contact with a stop plate 91, and the desired number of caramels is then moved laterally by a feed plunger 73. The group of caramels thus moved comes to rest between a sizing plunger 58 and the stop plate 91... Next, the plunger 58 moves forwards and squeezes the caramels until the total width of the group is slightly less than the width of a pocket 32 of a wrapping wheel 33. Finally, the plunger 73 continues its forward movement and pushes the group of caramels into the pocket 32, a sheet 25 of wrapping material being carried into the pocket by the group. The wrapping is completed by mechanism of the kind described in Specifications 13382/09, [Class 94 (i)], and 449,531. The Specification as open to inspection under Sect. 91, describes apparatus for folding and sealing the sheet 25. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the catalytic oxidation of organic compounds
Filed: 1927-12-21
Abstract: 303,268. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Dec. 21, 1927. Oxygenated organic compounds; acids; esters. -The treatment of organic compounds in the liquid state with a gaseous oxidant is effected in the presence of a catalyst comprising a compound of a metal with an enolizable organic compound, with or without a metal oxide. Suitable catalysts may be prepared by precipitating a metal salt solution with ammonia in the presence of an enolisable organic compound such as acetoacetic ester, acetylacetone, or benzoylacetone, the metal salt being present in excess with respect to the enolisable compound. In one example, a mineral oil containing a small amount of basic manganese acetylacetonate is treated with air at 150‹ C. In another example, the material treated is the neutral oxygenated compounds obtained after separating the acids from an oxidation product of higher aliphatic hydrocarbons, and this material is treated with a small amount of neutral manganese acetylacetonate and oxidized with air. Instead of manganese acetylacetonate there may be used the cerium, nickel, cobalt, or zinc compound of acetylacetone, benzoylacetone, or acetoacetic ester. In a further example, paraffin wax is oxidized with air in the presence of manganese acetylacetonate.

Title: Improvements in fluid operated streamline valves for flow or pressure control
IPC: F16K1/12
Filed: 1933-12-09
Abstract: 430,164. Fluid actuated valves. PLATTS, H. H., and GUEST & CHRIMES, Ltd., Don Street, Rotherham, Yorkshire. Dec. 9, 1933, No. 34686. [Class 135] A streamlined valve has a differential annular plunger 5 forming a movable valve member slidable in a cylinder 4. Fluid pressure from the inlet pipe 1, or from an external source, is led to both sides of the plunger 5 and a duct 10 leads from the large area side of the plunger 5 to the outlet side of the valve. A slidable plunger 8 adapted to open or close the duct 10 is linked to a loaded piston 14. Movement of the piston 14 causes the plunger 8 to vary the flow through the duct 10 so that the plunger 5 moves to open or close the valve. As shown, the piston 14 is actuated by the fluid pressure on the outlet side of the valve through a connecting pipe 15 so that a constant reduced pressure is maintained on the down stream side of the valve. In a modification, the piston is acted upon by the fluid pressure on the inlet side of the valve. Alternatively, the piston 14 may be subjected to fluid pressure from an external source, or it may be operated manually. In a modification, the opposite sides of the piston 14 may be connected respectively to the inlet and throat of a Venturi tube so that the valve will give a constant rate of fluid flow.

[Also in Group XXIV] A spindle for a textile machine has between the wharve 13 and a portion 12 of the rotatable blade, frictional material 14 and centrifugal clutch means 15, 16 such that when the wharve is initially driven the friction material transmits sufficient torque to rotate the spindle and so cause the clutch means to eventually establish a non-slip driving connection. The friction material is preferably in the form of rings 14 which are steel shells having working surfaces of polytetrafluorethylene-impregnated sintered bronze, the shells being fixed to the inside of the wharve. The clutch means comprise part annular, sintered bronze members 15 mounted to be radially movable on pins 16 protruding from the blade portion 12. A washer 17, similar in construction to the ring 14 is placed between the lower end of the wharve and a flange 12a to increase the frictional driving connection between the wharve and the spindle blade. An electromagnetically-operable brake member 18 is upwardly movable to engage a plate 19 fast on the lower end of the spindle blade. The brake may be automatically operated on breakage of the yarn.
