Title: Knitting machine
IPC: D04B15/66
Filed: 1972-04-06
Abstract: 1389613 Knitting-machines SINGER-ALEMANNIA MASCHINENFABRIK GmbH 6 April 1972 [6 April 1971] 16018/72 Heading D1C In a flat machine having at least one electromagnet e.g. 48 associated with each needle, the electro-magnets are arranged in groups G 1 , G 2  .. wherein one common terminal e.g. L1 of each group is consecutively connected via a switch e.g. S1 to one line 67 of an electrical potential. In a one or two bed machine the needles are controlled by jacks 31 and pivoted selector jacks 33. The selector jack butts 34 are selectively moved into knit, non-knit or tuck positions by a pivoted member 39 engaging the end of the selector jack. The member is maintained in a selected one of three positions by armatures 46, 47 of electromagnets 48 engaging in catches 44, 45. Once a selection for a first course has been made the lock crosses the needle bed and jacks are moved into knitting or tucking tracks by cams 53 and 55, and 57 and 59 respectively. Meanwhile the appropriate electromagnets have been energised, but due to their low power only when the selector jacks and members 39 have been reset by cam 35. A selection for the next course is thus determined. As shown electromagnets are arranged in groups of eight corresponding to four needles, each group being connected to the line 67 via a switch closed when a roller R is depressed by a cam 75 on the lock. The cam spans three rollers. Each electromagnet can be simultaneously actuated by thyristors 69 from outputs A of a pattern via diodes D, and. the needles selected as described above. The pattern is advanced stepwise as each roller is depressed, and information supplied to the groups of magnets if its switch S is closed and an appropriate signal X, Y or Z transmitted. If the machine has two locks per needle bed (Figure 5 not shown) cams 75 are provided for each and actuate alternate groups of magnets.

Abstract: 333,961. Flower, J. W. May 30, 1929. Bottling.-Relates to rotary bottling-machines of the counter-pressure type having a series of filling heads spaced around a feed pan for gas and liquid each provided with a rotary plug-cock operated by plungers acting on star wheels carried by the cocks which control the flow of gas and liquid through the heads. According to the invention, each head has a liquid flow tube 29 coaxial with a gas tube 30 which is shouldered at 33 to discharge the liquid radially. The machine has a number of filling heads operated by starwheels 35 and plungers 37<1>, 37<3>, which control the cocks 34. The feed pan 3 is provided with a gland 70 for the introduction of the liquid and gas supply tubes. In the event of a bottle not being placed on a bottle-holder for filling, the free end 57 of a semi-circular finger attached to a sleeve 55 presses the plungers out of action when the bottle-rest is raised to the filling position. The bottles are fed to the bottle-holders 17 from a conveyer 16 by means of a star-wheel 18, which is driven by the holders. In order to prevent bottles from jamming between the points of the star-wheel and a guide rail 20, a bell-crank lever is pivoted on the conveyer table 22. Rollers 19 rock the lever as they pass and turn the padded end of a lever 23 into the path of the bottles tc correctly span them. The bottles are raised to the filling and sealing positions by differential hydraulic rams operated from a cam-track by rollers on pistons, and relief valves are provided therewith to compensate for the different pressures required for filling or sealing. If a ram fails to descend it fouls a fence 48 and rocks it, and its motion is transmitted through suitable linkwork to the clutch on the main driving shaft to disengage the clutch. An adjustable swift valve 75 is provided in the pan 3, and check valves 68, 69 to prevent loss due to the breakage of a bottle &c.

Title: Improvements in or relating to crushing and mixing mills
Inventor: TODMAN JAMES JOHN
IPC: B02C15/14
Filed: 1951-07-13
Abstract: 729,427. Edge-runner mills. WINGET, Ltd. July 11, 1952 [July 13, 1951], No. 16727/51. Class 59. In a mill comprising a head 7 rotatably mounted within a pan 1 and having a plurality of rollers 8 coupled thereto so as to be caused to travel round the pan upon rotation of the head, the rollers are connected with the head by linkage mechanism which is movable relatively to the head and the linkage mechanisms or parts thereof are movable relatively to each other, the arrangement being such that any one roller is capable of upward and downward movement without necessarily producing an up and down or tilting movement of any other roller. As shown in Fig. 2, each roller is mounted on a stub shaft 9 the inner end of of which is connected with a bracket member 10 which is connected to the head 7 by means of two pairs of equal and parallel links 13. The stub shafts may be arranged with their axes in a common diametral line or may be offset, e.g. by means of spacing sleeves 33, Fig. 3, so that the axis of each shaft is parallel to but slightly in front of or behind such diametral line. The head 7 may be provided with arms 35, Fig. 3, which support scraping ploughs 36, 37. Compression springs 11 are interposed between projections 38 on the bracket members and bolts 14 screwed in a cross member 15 mounted above the head. Downward movement of the rollers 8 is limited by means of projections 17 on the bracket members 10 engaging the upper ends of bolts 16 screwed in projections on the head 7. The links may be arranged tangentially instead of radially. In a modification, Fig. 4 (not shown), the upper links are longer than the lower links so that the rollers tilt slightly as they move upwardly and downwardly in the pan. The tilting could, however, be obtained by arranging the links so as to be inclined to each other. In another modification, Fig. 5 (not shown), the upper pairs of links are replaced by a leaf spring which is rigidly connected at its centre to a support on the head. In a further modification, Fig. 6 (not shown), the upper pairs of links are replaced by a single pair of longer links which connect opposite bracket members and are arranged to work in vertical slots formed in guide arms projecting upwardly from the head. Specification 692,703 is referred to.
