Abstract: 225,871. Barrett Co., (Assignees of Cushing, D.). Dec. 7, 1923, [Convention date]. Drawings to Specification. Dry processes of refining metals; alloys. - A process for melting and refining non-ferrous metals and alloys such as copper, bronze, nickel, aluminium, tin, antimony, lead, and zinc comprises melting the metal in contact with incandescent pitch coke substantially free from sulphur, ash and phosphorus. The pitch coke used, which is obtained by coking coal-tar pitch, contains 98 per cent or more of carbon and may have a thermal value of 14,500 B.T.U. per pound. The process may be carried out in a cupola furnace to which air is supplied at a low pressure and is so regulated that a reducing atmosphere can be maintained near the metal and metallic oxides present as impurities can be reduced.

Abstract: 1,043,659. Couplings between pushed marine vessels. L. R. GLOSTER. July 9, 1965. No. 29325/65. Headings B7S and B7V. A thrust coupling closely connecting a tugboat 1, Fig. 1 (not shown), with a tow forward of the tugboat in the form of a barge 2 comprises a frame compression member tapered aft from its broad base 3 mounted by pivots 9 on the tow 2, and a second compression member in the form of a strut 10 spaced from the frame member so that the coupling straddles the bow portion of the tugboat 1. The widely separated pivots 9 limit movement between the frame and the tow to swinging about a lateral axis. Aft pivot means 12 and 13 are universal joints and pivot 11 at the tow end of strut 10 permits swing about a lateral axis and a vertical axis. Each of the vessels connected by the coupling can heave and pitch freely relative to the other vessel and can have more or less free relative movement but they cannot yaw or sway relative to one another. The tug may have a printed or a square bow and the tow may have a square or a rounded stern. A string of coupled barges may also constitute the tow for the tugboat. Disengagement mechanism can be fitted in the coupling and the coupling can be raised and supported in the tow or in the tug.

Abstract: 1,009,624. Knitting machine. F. MORAT G.m.b.H. Aug. 1, 1962, No. 29601/62. Heading D1C. A circular knitting machine has jacks selected by electromagnetic means which act selectively on swingable members of a pattern wheel. The pattern wheel comprises bars 4 which engage the needle cylinder to rotate the wheel therewith, jacks 5 radially slidable, when selected, by auxiliary jacks 6 engagable with the jacks 5 by swingable springs 7 and reciprocated by stationary cams K3. Each auxiliary jack (see Fig.2) has a foot 6h engaged by cams K 3  and is rockable about its lower edge to engage its bent section 6c with either the foot 5a (see Fig. 8) of jack 5 to connect it with the latter for withdrawal only or with notch 5b or 5c to connect it for movement in either direction. Cams K 1 , K 2  engage the ends of springs 7 except at a gap G where the ends pass between pole faces 8a, 8b of upper control and holding electromagnets and the pole face 9 of a lower electromagnet, (see Fig. 9). As each spring approaches the gap G the corresponding jack is positioned with section 6c above and between notches 5b 5c in withdrawn jacks 5. The spring is held in its raised position or falls into the field of magnet 9 according to whether control magnet 8a is or is not energized. A spring in the raised position is raised over the upper edge of K 2 , the lowered springs passing along the lower edge of the cam. Cams K 3  withdraw the auxiliary jacks until section 6c abuts the foot 5b when the auxiliary jacks associated with lowered springs 7 are moved, as the springs pass under cam K 2 , to engage their sections 6c with notches 5b. At the section 'M' each auxiliary jack moves outwardly, those selected by lowered springs carrying their jacks with them. At section 'N' auxiliary jacks still in the 'raised' position are depressed by cam K 4  to engage their sections 6c in notches 5c to locate the appropriate jack in its inoperative position and cam K 2  returns the springs to their intermediate position. At section 'B' cam K 1  raises all the springs, the auxiliary cams are lifted from notches 5b, 5c and at section 'C' cams K 3  first withdraw the auxiliary jacks and as parts 6c, 5a abut, the advanced jacks, and at section 'E' advance the auxiliary jacks to place section 6c above and between notches 5b, 5c as before. Specifications 871,864 and 947,457 are referred to.

Filed: 1921-11-07
Abstract: 187,855. Koerner, E. Nov. 7, 1921. Cigarette-making machines.- Mechanism for varying the cutting-stroke of a continuous-rod machine in which the cutter is actuated by a cam 3 on a shaft 2 comprises a worm-wheel 9 engaged by a worm 6 mounted together with a spur-wheel 10 on a spindle 6<a> carried on a forked arm 8, which is connected to a sleeve 4 driven from the main shaft by gearing 5. The spindle 6a also carries a rocking-lever 12 to which are pivoted spring-pressed pawls 11<a>, 11<b> engaging the spur wheel 10. A saddle-piece 15, attached to the lever 12, carries a roller 16 engaging a channelled ring 17 pivoted at 21 and returned to its normal position after displacement by springs 24. Normally the worm-wheel 9 is fixedly engaged by, and caused to rotate with, the worm 6, thus driving the shaft 2. If the channelled ring 17 is displaced about the pivot 21 by means of a handle 23, the lever 12 is slightly rotated on the spindle 6<a> at each revolution, thus causing one of the pawls to rotate the spur-wheel 10, the other riding up over a cam-face 18. The consequent small rotation of the worm 6 effects the advance or retard of the cutters. Stops 26 limit the movement of the ring 17. An arm 7 carries a balance-weight. 20.
