Title: Improved cocoanut shredding machines
IPC: A23N5/03
Filed: 1925-05-20
Abstract: 236,900. Hills Bros. Co., (Assignees of Gentel, C. H.). July 10, 1924, [Convention date]. Lathes; chucks.-A half coco-nut is placed between two spring-closed gripping arms 64 pivoted in a plate 62 having marked thereon a circle 69 to assist in positioning the nut. The pate is provided with a handle and its base 59 is carried in slides 60 extending across a longitudinally movable table 56. The. table 56 is moved until the coco-nut can be pushed forward into the jaws 36 of a rotating chuck, its rounded end bearing against a spring 53 in the centre of the chuck. The chuck comprises a body 27, to which, are pivoted bell-crank levers 32 actuating the jaws 36, and a sliding portion 28 having sockets to contain balls at the extremities of the short arms of the bell-crank levers 32. The jaws 36 move in slots formed in projections from the body 27. A groove 37 is formed in the sliding portion 28 and is fitted with a ring 38 connected by a link 40 to an operating lever 41 pivoted on a bracket 25, and provided with a locking device comprising a ball normally pressed by a spring into position between converging surfaces on the lever and the bracket but adapted to be moved into non- locking position by a handle 50. After the nut has been gripped in the chuck the holding device is withdrawn and the table 56 moved along its rails 58 until the tool 70 is opposite the chuck. The tool has several cutting edges 71 and is secured in a pivoted holder 72 by a screw 73. The holder is normally urged by a spring 77 to bring the tool against the inner wall of the nut and is mounted in a stand 76 movable in guides 79. The holder is fed forward by a half-nut 86 on a lever 84 pivoted on the stand 76 engaging a rotating screw 80. A spring tends to throw the half-nut out of engagement with the screw, but is normally maintained inoperative by a dog adapted to. be tripped when the tool 70 is fed forward sufficiently to be approximately in line with the axis of the chuck. The screw 80 is mounted in brackets depending from the table 56 and is driven from a shaft 88 having a bevel gear meshing with a bevel gear 102 on a vertical shaft 100 mounted in a bearing also depending from the table 56. A second bevel gear 101 on this shaft meshes with a bevel gear 98 on a sleeve 97 splined to a shaft 19 and mounted in a bearing on a circular table 95 movable about an axis directly below the axis of the shaft 100. At its other end the shaft 19 is supported by a bearing 18 mounted on another table 16 movable around a shaft 14 to which the shaft 19 is connected by gears 20, 15. The shaft 14 is connected to the shaft 23 of the chuck by gears 21, 22. A belt 105 passes over a pulley 104 on the end of the shaft 83 and drives a shaft 107 having a pulley 103 over which passes a broad endless belt 109 to discharge the shreds of coco-nut. This broad belt is bent back sharply under the pulley 108 to permit the shreds to fall into receptacles.

Title: Apparatus for bonding sealing rings to closure cap shells
IPC: B21D51/46
Filed: 1963-04-04
Abstract: 1,043,881. Making crown closures. OWENS-ILLINOIS Inc. April 4, 1963 [April 4, 1962], No. 13322/63. Heading B8T. An apparatus for bonding a sealing ring 24 to the inner surface of a closure cap shell 23, Fig. 9, comprises a horizontal heatable rotatable ring 22, Fig. 2, mounted on posts 21 connected to a turret plate 18, and a plurality of press heads 25 mounted for vertical reciprocation immediately above and rotatable with the ring. Closure cap shells containing positioned sealing rings are fed open-side uppermost by a star-wheel mechanism on to the horizontal ring; at the same time a cam-actuated presshead descends partially into the shell prior to the latter, moving beyond control of the starwheel. The press-head then moves into contact with the sealing ring which has an adhesive 23a between itself and the cap shell, which adhesive is rendered tacky by the heated ring. Each press-head 25 is attached to a holder 28, Fig. 5, which depends from a piston 29, the latter being telescoped into a tube 29a, partly within a vertical housing 30, which is secured to a frame 26. A cross-bolt 32 permits relative movement between the piston and the housing, and a spring 34 acts as a shock-absorbing cushion during the halting of each downward stroke of the press-head. A screw 36 carried by a plug 35 functions to regularly control the spring tension. Reciprocation of the press head is effected by a roller 37 mounted at one end of a shaft 38 running in a cam 41, Fig. 2. At the other end of the shaft a guide roller 39 runs in a vertical guideway 40 to prevent rotation of the press-head. The press-head is tapered exteriorly and is formed with a rib 25a which contacts the sealing ring; a pair of diametrically-opposed flat surfaces 25b enable stripping plates to contact the cap shell at a discharge unit to prevent upward movement of said cap shell during retraction of the press-head therefrom. Heating of the heatable ring is effected by heater cartridges 46 mounted in recesses 47 to which current is supplied through conductors 49 via relatively movable conductor rings 52, 53.

Title: Method and apparatus for separating oil from aqueous liquids
IPC: B01D17/04
Filed: 1976-04-01
Abstract: 1501554 Oil/water separation W F CHAPMAN 1 April 1976 13331/76 Heading BID A separator device for removing oily particles from admixture with aqueous liquid comprises a vessel 16 having a mixture inlet 11 leading to an inlet chamber 12; a mass of oleophilic granules 17 of a specific gravity greater than water resting on a foraminous support 14 through which the mixture is directed to flow upwardly, e.g. by cylindrical baffle 13, so as to lift the granules individually and free from mutual support into a contact zone above the support 14, whereon the granules coalesce the oil and release it back to the mixture flow as droplets; a screen 19 inclined at least 75‹ to the horizontal mounted above the contact zone which allows passage of aqueous liquid but captures oil as a film on its surface for upward flow via a solid oil flow path to an oil collection chamber 21 mounted above the screen and oil outlet 24: and an aqueous liquid outlet 26 for removal of aqueous liquid that has passed the screen. The mixture is pumped into the separator at a rate, e.g. 6 - 90ft. min, such that the oleophilic particles (which may have a specific gravity of 2.0-3.5) are lifted but tend to descend under gravity against the flow so that they move up and down in the flow. The bed of granules may be divided by baffles 18 into a number of parallel beds. The screen 19 is mounted a sufficient distance above support 14 to ensure it is not contacted by the lifted particles. The solid oil flow path is suitably formed by the walls of baffles 13 and the baffle defining the oil collection chamber. The baffle 13 may be notched at its upper end to allow overflow of water which is directed firstly downwardly by baffle 28 as a precaution to maintain the oil-water interface level upon tilting. The water level Y-Y is suitably maintained above the oil level X-X to maintain a through - flow of the latter, which may be controlled by level sensor valve 23. The separator device may be arranged with rectangular rather than cylinderical symmetry (Figs. 3 and 4 not shown). The device may be used to treat small industrial flows leading to sewage, in large industrial systems, e.g. oil refineries, oil fields, oil drilling platforms or harbour terminals with flows discharging into natural waters, or on board ships. A number of the separators may be mounted in parallel in a common housing.

If an additional load of snow or rain water rests on the deck so causing further submergence of the roof, then the pontoon A assists in supporting this load.
Patent GB-799567-A (GB)
Title: Process for the production of alpha-epichlorhydrin
Filed: 1957-04-26
Abstract: a -Epichlorohydrin is continuously prepared by treating an aqueous mixture of glycerol dichlorohydrins with a basic substance, extracting the epichlorohydrin with a water-immiscible solvent circulating counter-current to the aqueous flow, recovering the epichlorohydrin outside the dehydrochlorination zone and recirculating the solvent for a further extraction.  The preferred solvent is 1:2:3-trichloropropane and other solvents mentioned are hydrocarbons such as benzene, toluene and xylenes; halogenated hydrocarbons such as carbon tetrachloride, trichloroethylene, perchloroethylene, chloropropenes, chloropropanes, chlorobutanes and chlorobenzenes; ether oxides such as butyric or amylic ether; ketones such as methylpropylketone, ethylpropylketone, methylamylketone, 5-methylhexanone and ethylamylketone; esters such as a -methyl propyl acetate and butyl or amyl propionate.  The preferred basic substances are hydroxides or carbonates of the alkali and alkaline earth metals. A continuous working process is described in which the aqueous solution containing the dichlorohydrin enters at the bottom of a tower, the base is added at the bottom and at various heights on the tower and the organic solvent runs down the tower from the top.  The aqueous solution removed from the top of the tower contains almost exclusively salt and excess base while the organic layer removed from the bottom contains epichlorohydrin, the dichlorohydrins and a little water.  The organic layer is dried by distilling off the water as an azeotrope with epichlorohydrin, separating the two immiscible liquids and running the epichlorohydrin back into the dry organic layer. This layer is further distilled to remove the epichlorohydrin and the residue is extracted with water to remove and glycerol dichlorohydrin that may be present.  This aqueous solution is run back to the bottom of the dehydrochlorinating tower and the purified solvent back to the top.  These various cycles are shown diagrammatically on a flow sheet.  An example is given using 5N sodium hydroxide solution as the base and 1:2:3-trichloropropane as the solvent.

H., 1, Lichtensteinallee, LEBEDENKO, N., 10, Holsteinischestrasse, Wilmersdorf, and DOBROBORSKI, B., 3, Joachim Friedrichstrasse, Halensee, all in Berlin. May 9, 1933, No. 13482. Convention date, May 11, 1932. [Class 80 (iii).] Three or more swash-plate units, arranged side-by-side on a common shaft, are mutually so related that they produce dynamic balance. The units are of the kind comprising an oblique track, rotating with the shaft, and a non-rotary ring, freely-mounted on the track and engaging a series of piston-members, disposed around and parallel with the shaft. The forces produced by the wobbling of each ring and the reciprocation of its associated pistons, resolve into a couple, rotating in a plane normal to that of the shaft, and represented by a screw-vector such as L, M, P, at right-angles to the diameter of maximum inclination of the plate. These couple-vectors are resolved into two planes zox, zoy, at right angles, whereupon similar or dissimilar plates can be balanced by a suitable choice of the phase-angles. Three similar plates, as shown, balance with a relative phasedisplacement of 120‹. Four similar plates balance when the individual plates of any pair, have a 180‹ phase-displacement.
