Class 83 (3) Indexing mechanism for the turret of an automatic lathe embodying a Geneva mechanism is characterized in that means are provided for automatically engaging with the Geneva wheel one or other of two dog carriers having a different number of dogs thereon. The turret 10 is rotated by gearing 12, 13 from a shaft which carries a Geneva wheel 14 at one end. This wheel may be moved to index the turret through one station or more than one station at a time according to whether a member 17 is in its lefthand or right-hand position, Fig. 1. One member 17 has two flange portions, one 15 carrying two rollers 19, Fig. 3, and the other 16 carrying only one roller 18, Fig. 1, and is secured to a sleeve 20 normally moved to the left by a spring 26 and is rotated at timed intervals by a onerevolution clutch 21', 22. In the position shown, Fig. 1, the roller 18 engages a slot in the Geneva wheel and thus rotates the turret one station, but when a follower 27 is allowed to move into a cam groove on an extension of the member 17, the latter is moved to the right and the two rollers 16 on the disc 15 engage successive slots in the Geneva wheel and the turret is indexed two stations. Automatic locking and timing means 35, 25 respectively, Fig. 4, are provided so that the turret is locked in accordance with its angular rotation. Specifications 712,243, [Group XXIV], 712,244 and 712,245 are referred to.

Filed: 1972-03-06
Abstract: 1377552 Balancing reciprocating parts ACIERS ET OUTILLAGE PEUGEOT 6 March 1972 [1 April 1971] 10325/72 Heading F2X A balancing device for a hand tool, in particular a jig-saw, comprises two gear-wheels 20, 21 loosely mounted on a shaft 22 parallel to the shaft 1 of the electric motor M and carrying balancing weights 23, 24. The toothed end portion 4 of the shaft 1 meshes both with a gearwheel 5, which transmits the drive of the motor M to the tool carrying means 13, and the gearwheel 21 whereas the gear-wheel 20 only meshes with the gear-wheel 5. The gear-wheels 20, 21 may be made from a thermoplastic material in which case the balancing weights are secured to the gear-wheels. Where the gear-wheels are made from a metal or alloy of suitable density, the weights are in one piece with the gear-wheels. In either case, the gear-wheels have the same number of teeth and the same pitch diameter with corrections made to the teeth of the gearwheels such that their outside diameters are different. Thus the gear-wheel 20 of larger outside diameter meshes with the gear-wheel 5 whereas the gear-wheel 21 of smaller outside diameter clears the teeth of the gear-wheel 5. When the motor M operates, the toothed end portion 4 of the shaft 1 drives the gear-wheel 5 and the gear-wheel 21. The gear-wheel 5 drives the gear-wheel 20 in the opposite direction to gear-wheel 21 but at the same angular velocity.

Abstract: The invention relates to cycloheximide thiosemicarbazone, which is prepared by dissolving cycloheximide and thiosemicarbazide in a solvent such as aqueous or non-aqueous dimethyl formamide and precipitating the thiosemicarbazone by the addition of a non-solvent such as water.  Cycloheximide thiosemicarbazone is less phytotoxic than cycloheximide and has fungicidal and insecticidal properties (see Group VI). Specifications 639,943 and 644,919 are referred to.ALSO:Pesticidal and particularly fungicidal compositions comprise cycloheximide semicarbazone (Group IV(b), and a diluent or carrier therefore.  They are less phytotoxic than compositions containing cycloheximide per se.  Cycloheximide semicarbazone may be dissolved in a water-missible solvent such as dimethylformamide or dimethyl sulphoxide and added to water with or without the further addition of a non-phytotoxic oil, wetting spreading, dispersing agents, stickers and adhesives.  The composition may also be in the form of a powder especially a dispersable powder. The composition may be applied to animal and vegetable materials such as rawhide, leather and cotton fabrics.  Specifications 639,943 and 644,919 are referred to.

Abstract: 504,220. Winding bobbins. HAMEL, E. April 6, 1938, No. 10521. [Class 120 (ii)] The pivoted bobbin-holder of a drum winding-machine has one or both of the arms, carrying the pivots for the bobbin, provided with members forced by a spring or other constraining means to engage a member having inclined surfaces so that as the holder is moved away from the drum for changing the bobbin, the inclined surfaces force the arms apart to release the bobbin. As shown the arms 4 carrying the bobbin pivots 3 are mounted on a shaft 5 and carry pins 6 urged together by a spring 7 so that their ends engage the member 8 having inclined surfaces 8<1>, 8<11>. In the winding position the pins engage the surfaces 8<111> and when the holder is swung upwards from the drum to change the bobbin the pins move over the surfaces 8<1> to the surfaces 8<11>, the pins and arms being separated against the action of the spring 7 and the bobbin 1 dropping from the pivots 3. In a modification, one arm only is moved as the holder is swung away from the drum.
Patent GB-372067-A (GB)
Title: Improvements in or relating to the separation of gaseous mixtures
IPC: F25J3/02
Filed: 1931-04-09
Abstract: <PICT:0372067/III/1> In the low-temperature separation of gaseous mixtures by partial liquefaction or by washing with a solvent, the necessary cold is produced by the rectification of a low-boiling liquid in the atmosphere of a non-condensable auxiliary gas.  This liquid flows down a rectification column through which the auxiliary gas passes upward taking with it the low-boiling components, while the remaining component is obtained in a pure state at the bottom of the column.  The liquid undergoing rectification is preferably that obtained by the washing or liquefaction of the gaseous mixture.  The Figure shows the application of the invention to the separation of a mixture of hydrogen, carbon monoxide, methane, and nitrogen.  This passes up the column 1 and is washed with liquid methane, supplied at 4; the gas thus enriched in hydrogen leaves the apparatus at 3.  The contaminated washing liquid is introduced at 8 into the outer column 7 and meets an ascending current of auxiliary gas entering at 11. The carbon monoxide and nitrogen are thus expelled and the purified liquid methane is withdrawn at 9 and recirculated to the washing column.  The auxiliary gas may be a part of the purified hydrogen withdrawn from the point 10; it may be admixed with nitrogen admitted by the pipe 12, in which case the nitrogen is partly dissolved by the methane and liberated again during the washing process, so that a gas mixture suitable for ammonia synthesis is taken off at 3.
