Title: Apparatus for Moulding Confectionery.
IPC: A23G3/02
Filed: 1915-12-21
Abstract: 102,919. Marks, E. C. R., (NationaL Equipment Co.). Dec. 21, 1915. Depositing-machines.-Relates to tray tumblers for use in machines for moulding confectionery such as that described in Specification 17858/15, and consists in arranging spring-pressed clamps on the tumbler to engage the sides of the tray as the tumbler commences to rotate. The device described comprises two similar parts on each side of tha machine, rigidly connected together so as to act in unison. As shown in Figs. 2 and 3, which show one half of the device, a tray b is supported on runners 19 carried by a bracket 15 adjustably secured to an arm 14 keyed to a shaft 13 by which the tumbler is operated. The brackets 15 on each side of the machine are connected by tie-bars 18, and on each bracket is a resiliently-mounted jaw 21 adapted to engage lightly the edge of the tray b. In the position shown, the projecting part of a stationary face-cam 31 engages a roller 30 on a bell-crank 28, one arm of which engages beneath a nut 29 on a rod 24 carrying a plate 25 and holds the plate 25 out of engagement with the resilient jaws 21. When the tumbler commences to rotate, the roller 30 runs off the projecting part of the cam 31, and a powerful spring 26 causes the plate 25 to bear firmly upon the bar 21 and thereby secure the tray during rotation.

Patent GB-927321-A (GB)
Title: Conversion of flavonoid substances
IPC: A23L5/20
Filed: 1959-05-25
Abstract: Naringin in aqueous solution is converted to prunin by the action of 0.01 to 0.5% of an enzyme preparation containing naringinase, the process being effected in the presence of one or more glucose, gluconolactone, mannose, gluconic acid, tannic acid and cyclohexyl-b -d-glucoside, to inhibit enzymic conversion of prunin to naringenin. Preferably 40 to 200 parts of glucose or 1 to 5 parts of gluconolactone are added for each part by weight of naringin, and the enzymic treatment effected at a pH within the range of 3 to 7 and at a temperature of 5 DEG  to 60 DEG C.  The enzyme preparation may be obtained by inoculating a cooled, sterile, growth medium containing naringin, nitrogen and fruit pulp, with spores of a strain of Aspergillus Niger and shaking the medium for 2 days, the pH being within the range 3 to 7 and temperature within 20 DEG  to 35 DEG C. Small amounts of this culture are then used to inoculate larger volumes of the original growth medium shaking under the same conditions, being effected for approximately 4 days.  The enzyme is then precipitated, collected and dried at 10 DEG  to 35 DEG C. to yield a crude extract which may, if desired, be treated with the thiourea or urea to separate enzymes acting on pectin from the naringinase.ALSO:The bitter taste of naringin in aqueous solutions, e.g. in fruit juices, is decreased by converting at least 15%, preferably at least 50%, of it to prunin by the action of an enzyme preparation containing naringinase, any enzymic conversion of the prunin to naringenin being restricted so that the amount of prunin in the final solution is equivalent to at least 15% of the original naringin.  The enzyme preparation is admixed with, and at least partially dissolved in, the juice, e.g. grapefruit juice expressed from the culls and/or peel of the fruit, and the process is effected at a pH within the range 2.5 to 9, preferably 2.5 to 5.5, and within a temperature range of 5 DEG  to 60 DEG  C., preferably 25 DEG  to 50 DEG  C., the conversion of prunin to naringenin being restricted by adding excess glucose to the juice or by inactivating the enzyme preparation, e.g. by heating, freezing or adding strong acids or alkalis.  By carrying out the process in the presence of one or more of glucose, gluconolactone, mannose, gluconic acid, tannic acid, and cyclohexyl-b -d-glucoside the conversion of prunin to naringenin is substantially inhibited and prunin may be recovered from the treated solution.  Preferably 40 to 200 parts of glucose and/or 1 to 5 parts gluconolactone, by weight, are added for each part of naringin.

Title: Improvements in or relating to the production of shaped articles from powders
Inventor: PENRICE THOMAS WILLIAM
IPC: B30B15/02
Filed: 1954-06-22
Abstract: 781,982. Compacting powders. PRODUCTION TOOL ALLOY CO., Ltd. June 15, 1955 [June 22, 1954], No. 18307/54. Class 87(2). In a method of compacting powder by the application thereto of pressure in a closed space, a reversible lyophilic gel is interposed between the powder and the source of pressure, or between the powder and the containing walls of the closed space. The gel is such that if it is deformed under pressure it will, on release of the pressure, return to its original shape and dimensions. The object of the invention is to achieve even compacting. As shown in Fig. 1, a spherical metal ball is made from powder by the stages A ... E. In A a spherical pattern 4 is supported on a bottom plunger 2 in a die 1, and molten " Vinamold " (Registered Trade Mark-plasticized P.V.C.) is poured into the die and allowed to set to form a compressible mould 5. The flexible mould thus made is removed from the die, the pattern is withdrawn and the mould is inverted and replaced in the die (stage B). Metal powder 7 is then filled into the mould, a separately-produced " Vinamold " plug 6 (stage C) is placed on top of the powder within the mould, and a pressure of 10 tons p.s.i. is applied to the powder by means of a plunger 3 (stage D) or plunger 2 or both plungers. The mould is thereby compressed and the metal powder is compacted and made smaller in volume. The pressure is then released, a small metal ball compact remaining in the mould cavity (stage E). Fig. 2E illustrates a modification for making a cylinder 7, the cylinder being shown after it has been compacted in the space between the die 1, a " Vinamold " core 5 and a " Vinamold " cap 6. Fig. 3E illustrates another modification for making a tube 7, the tube being shown after it has been compacted between the mould 5, 6 and a steel core 9. In modifications which are not illustrated, (a) a mandrel or core may itself be made of compressed but unsintered powder not necessarily of the same composition as the powder around it, so that an article of varied composition may be produced, and (b) a cylindrical tungsten carbide body pointed at one end is made. The material placed in the mould may have been initially partly compacted. Instead of " Vinamold " the mould may be made of organo gels in general, soft vulcanized rubber or lyophilic gels such as gelatin, agar agar, egg albumin or alginic acid gels.

Abstract: 498,297. Softening water. ELECTROLUX, Ltd. (Bengtsson, A. E.) July 1, 1937, Nos. 18318 and 29629. [Class 46] In water-softening apparatus of the base-exchange type, a retaining and /or supporting member for the bed of softening material comprises an agglomerate of solid grains such as sand or quartz held together by a binding agent, the member being formed with pores of sufficient fineness to hold back particles of the bed and consisting of grains of a size not finer than obtained by separation by means of a sieve having twenty meshes per inch, and being graded between sieves not exceeding eight meshes per inch difference. In the construction shown, zeolitic material is supported on a plate 11 formed of sand or quartz grains bound together by a binding agent such as synthetic resin. The amount of resin preferably does not exceed 5 per cent by weight of the solid particles. Below the plate 11 is a space 21 provided to ensure that flushing water through the outlet 13 is spread uniformly over the whole surface of the plate. The plate may be supported on the base 22 through the interposition of a packing ring 12. In a modification, the plate is secured by bolts to an annular flange extending inwardly from the wall of the container, and the inlet and outlet pipes are connected to a multiple-way valve. The grading of the grains forming the retaining member is according to United States standards.
