Abstract: <PICT:0981211/C6-C7/1> In a process for the manufacture of a citrus fruit product comprising comminuting the fruit in bulk or limited bulk quantities in a plurality of comminuting devices, the fruit is directed to the comminuting devices by feeding it to a jigging conveyer having a plurality of guideways extending to respective comminuting devices, feeding of the fruit to the guideways being assisted by the jigging action.  Oranges are discharged on to a shaker conveyer 23, Fig. 1, from the lower end of skips 10, Fig. 3, which are supported on a cammed (17) rocker shaft 16 actuated by a hydraulic motor 18. From the shaker conveyer the fruit is elevated by a conveyer 25 to a hopper 34 from which it is loaded into compartments of a Ferris wheel 38 upon withdrawal of a baffle 36 by a hydraulic motor 37.  (An optional weighing <PICT:0981211/C6-C7/2> <PICT:0981211/C6-C7/3> mechanism is not shown.)  During the anticlockwise rotation of the wheel the fruit passes through a bath of steam-heated water located in the lower part of the wheel and then falls down a shoot 50 into one of two jigging conveyers 51, 52, Fig. 2.  The first section of each jigging conveyer at 53, 54 is smooth surfaced and this leads to four corrugated guides at 55, 56, for delivering the fruit through vertically-disposed guide tubes to the respective one of eight comminuting devices 63 of the form described in Specification 934,348.  The liquid fruit product and solids resulting from the comminution are fed by screw conveyers 70, 71 to a collecting hopper 74 for separation as described and claimed in Specification 934,348.  Operation of the hydraulic motor 37 may be regulated by cam pegs 83 and 84 on the Ferris wheel cooperating with cam followers 85 and 86.  Means (unspecified) may be provided to prevent overfeed of fruit into the Ferris wheel.

Abstract: 710,770. Rolling. MASCHINENFABRIK MEER AKT.-GES. Sept. 19, 1951 [Sept. 19, 1950], No. 21997/51. Class 83 (4) In an adjustable device for intermittently feeding stock to a pilger rolling mill a screw spindle b carrying the work-piece is moved by a hydraulic ram m engaging a sleeve k screwed on the spindle b and constantly rotated to move along the spindle b in a direction opposite to that of the feed by an infinitely variable gear g the amount of feed being determined by the distance the sleeve k is screwed away from a stop al. The ram m and a clamp f for the spindle bare controlled by a pair of cams c, e. During feeding motion the cam c actuates a valve d supplying pressure fluid to the ram m which forces the sleeve k forward until it engages the stop a1. The cam e simultaneously moves a roller t against springs v to release the clamp f through linkage w to free the spindle. At the completion of the feeding stroke the cam c actuates the valve d to release the pressure in the ram m and the cam e releases the roller t so that the clamp f is actuated by the springs v to hold the spindle. During this period the sleeve k which is constantly rotated at any required speed through the infinitely variable gear g, pinion h and a toothed ring i on the sleeve, screws backwards along the spindle b the required distance of feed, forcing fluid out of the ram m.

Filed: 1953-08-14
Abstract: The invention comprises a process for the separationof gamma benzene hexachloride from a mixture containing the alpha and gamma isomers, the latter in excess, by treating with dimethyl carbonate so that most of the alpha is taken into solution, and separating the gamma product.  The process may form part of a continuous process for the photo-chlorination of benzene below 0 DEG  C. in a solvent to obtain the alpha and beta hexachlorides with substantially no gamma isomer, neutralizing, adding a recycled mixture of gamma and alpha isomers, treating to enrich the residue in gamma isomer and treating the residue as above.  Delta isomer formed in the chlorination is carried away in a residue not used for re-cycling.  The dimethyl carbonate may be used in admixture with a solvent so that the mixture has a solubility ratio for gamma to alpha isomers not exceeding 2:1.  Other gamma concentrates may be used.  A further continuous method of working is described in the example.  Benzene is chlorinated in methylene chloride at - 25 DEG  C. with mercury are light so as to give a product containing solid a  and b  isomers of the hexachloride, in a solution which is neutralized, mixed with recycle material, filtered and evaporated to give a gamma concentrate which is dissolved in dimethyl carbonate and cooled to precipitate high purity gamma crystals.  The residue is recycled as above.  Other solvents may be mixed with the dimethyl carbonate.  Specifications 573,693, 586,439, 586,442, [all in Group IV], 678,577 and 743,913 are referred to.
