Title: Improvements in or relating to Multiple Yarn Feeding Apparatus for Knitting Machines
IPC: D04B9/26
Filed: 1966-07-21
Abstract: 1,156,304. Knitting - machines. VYZKUMNY A VYVOJOVY USTAV ZAVODU VSEOBECNEHO STROJIRENSTVI. 21 July, 1966 [24 July, 1965], No. 32858/66. Heading D1C. In a stripping device for a circular machine, pivoted yarn guides are swung into active positions by a series of pivotally interconnected slides raised by a cam. There may be two, three or four guides in a device. As shown the yarn guides 1 are pivoted downwards about an axis 13 at their centres, into an active position 1' to lay yarns to the cylinder needles 7. In a modification (Fig. 1, not shown) the guides are pivoted at one end and raised into an active position to lay yarns to dial needles. Each guide is moved by pivoting slides 8-10, of which slide 8 has a slot 15 engaging pin 14 which together determine the vertical and horizontal movement of the guide when the slides are raised. The slides are raised when slide 10 is pushed into the path of lifting cam 11 by a pivoted lever (22) selectively moved by a cam drum (23) racked by a pawl at the dictates of the pattern drum. A lug 51 on lever 20 holds the guide in its operative position until released. Guides of outgoing yarns are released when cam 36 is slid under cam 33 which in turn engages lug 52 of lever 20 to release lug 51. If the device is to be capable of feeding two yarns together or if all the guides are to be rendered inoperative, a two step cam 36 operated independently of the cam drum (23) raises a two step cam 33. Each lever 20 has a two step lug 52 and all the guides are rendered inoperative by raising cam 33 to the greatest extent. For reinforcing, the cam is raised half-way pushing a full slug 52 of one lever aside so that its associated guide is inoperative; the other guide, having a two step lug, remains operative. Both guides are rendered operative by lowering the cam.. Yarns going into or out-of operation catch the top or bottom of the front face of a guiding plate 12 and are thus laid vertically and accurately between the needles.

Title: Improvements in or relating to package irradiation systems
Inventor: HOLLAND WILLIAM HENRY
IPC: G21K5/02
Filed: 1960-09-26
Abstract: 934,217. Irradiating articles. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Sept. 22, 1961 [Sept. 26, 1960], No. 33064/60. Class 98 (1). Articles such as packages are irradiated by being passed into a chamber within which are a plurality of rail track circuits, along which run trolleys conveying stacks of packages repeatedly past a radiation source; means are provided for conveying a package from a trolley on one rail to a different level on a trolley on another rail, and also for transferring packages from a trolley to the conveyers carrying the packages into or out of the irradiation chamber. In the form shown, monorail tracks 3, 4 are suspended from the roof of the cell 1, and trolleys 5 can run thereon. Each trolley has three spaced-apart support plates 6, so that three packages can be loaded on the trolley one above the other. The packages are introduced by a conveyer 8 into the irradiation chamber through an aperture in the wall (loading position a), and pushed by a push rod 9 on to the upper plate 6 of the outer trolley 5 (position b1] The trolley makes a complete circuit of the track, passing right round the irradiation source 2, and ending at position c1. Here it is pushed by a rod 10 on to the top plate 6 of the trolley 5 on to the inner track (position d1) and once more makes a complete traverse of the track in the opposite direction, finishing at position e1. In this position, the inner track 3 is lowered vertically, so that the top plate 6 of its trolley is level with the middle plate 6 of the outer trolley. The package is pushed across from one trolley to the other, so that it is now back on the outer trolley but occupying the middle position instead of the top position. The above procedure is repeated, with the package making the double circuit round the source 2 again, first on the outer and then the inner track. The inner track 3 is lowered again, and the package thus transferred to the bottom position on outer trolley 5. The double circuit is repeated once more, and then the package is finally pushed from its last position e4 to an unloading position f and conveyed out of the chamber. Thus the package is carried twice right round the source 2 at each of three different levels. Several packages may be traversed through the irradiation cell at the same time, in phased succession. Specification 927,364 is referred to.

The catalyst contains the lithium hydrocarbon in such proportions that the ratio of this second component to titanium halide is between 1.3:1 and 3.5:1 on a molar basis. The Periodic Table is that shown in the Handbook of Chemistry and Physics, 39th Edition, pages 400-401, published by the Chemical Rubber Publishing Company, Cleveland, Ohio (1958).  Specified (b) compounds are aluminium diethyl hydride, aluminium triethyl, tri-isobutyl, triphenyl, and triallyl, aluminium diethyl monochloride, aluminium monoethyl dibromide, aluminium diisobutyl monobutoxide, or benzoate, aluminium diethyl-beta-naphthoxide, -diphenylamine, -piperidyl, magnesium naphthyl chloride, magnesium phenyl chloride, magnesium diphenyl, zinc diethyl, lithium butyl, sodium amyl, lithium-aluminium tetraethyl, calcium-magnesium tetraethyl, and magnesium aluminium pentaethyl. The (c) ingredient may be obtained from I2 per se, iodine monochloride, iodine monobromide, and hydrogen iodide. The lithium hydrocarbon may be lithium ethyl to dodecyl, dilithium methylene, ethylene, or hexamethylene, lithium allyl, phenyl, or naphthyl, or 1,4-dilithium benzene, and if desired the lithium hydrocarbon may be formed in situ, by the reaction of lithium metal or hydride with butadiene.  The polymerization and preparation of the catalyst is generally effected in a conventional hydrocarbon diluent.  The polybutadiene is recovered and purified by conventional techniques, e.g. addition of ethanol.
