N<SP>1</SP>-(1-methylallylthiocarbamoyl)-N-<SP>2</SP>-methylthio-carbamoylhydrazine (methallibure) particles are stabilized by coating substantially the whole of their surface with a water-repellant, non-toxic, orally acceptable fatty or waxy substance being a saturated or unsaturated aliphatic acid, a monodi or tri-glyceryl ester thereof, or an ester thereof with a fatty alcohol, or a fatty alcohol, or a paraffin hydrocarbon, of mpt. 30‹ to 120‹C and in which methallibure is essentially insoluble, or a mixture of such substances. The fatty or waxy substance may be a hydrogenated derivative of an oil of animal or vegetable origin e.g. hydrogenated castor, whale, ground nut or palm oil; stearic or palmitic acid; cetyl, stearyl or cetostearyl alcohols; spermacetic, Chinese wax, beeswax, paraffin or microcrystalline wax. The particles may contain from 0.5 to 10 parts by weight of fatty or waxy substance to one part by weight of methallibure. Veterinary compositions e.g. in the form of pre-mixes or medicated animal feedstuff comprises the particles together with a non-toxic diluent or carrier e.g. ground chalk, kaolin, talc or ground maize. The particles may be formed by adding powdered methallibure to the molten fatty or waxy substance, or mixture thereof, stirring and cooling the resulting mixture to form a friable mass which may be further broken up, ground and sieved to give a powder of particle size preferably below 350 microns. Alternatively powdered methallibure may be mixed with the fatty or waxy substance in powder form and the mixture is passed through a mill under conditions causing the fatty or waxy substance to melt and coat the particles of methallibure or a solution of the fatty or waxy substance in a volatile organic solvent may be sprayed on to the surface of particles of methallibure which becomes coated on evaporation of the solvent.

Abstract: 359,255. Winding conical bobbins. SCHARER, (nee NUSSBAUMER), L. and SCHARER, K. J., (trading as SCH€RER-NUSSBAUMER & CO.), Erlenbach, Zurich, Switzerland. Nov. 20, 1930, No. 34880. Convention date, Nov. 26, 1929. [Class 120 (ii).] A machine for winding cop-shaped bobbins with crossed or parallel windings is provided with means to drive the bobbin spindle at a varying speed comprising an eccentric wheel which positively drives the spindle and reciprocates a slide to which it is directly coupled, the slide carrying a pair of spindle driving, helical gear wheels. The main shaft 3 driven by a friction wheel and a disc 2 carries a worm 4 engaging with a worm wheel 5 on a shaft 7, this shaft also carrying an eccentric wheel 8 and a cam wheel 20. Rollers 10, 11 attached to a slide 12 mounted on stationary guidebars 1211 ride on a projecting rim on the eccentric wheel, and a pinion 13 on the shaft of the roller 11 engages a toothed rim on the wheel, this shaft being mounted in the slide and carrying also a screw gear 14 which meshes with another screw gear 15 integral with a sleeve 17. A forked arm 12<1> of the slide engages in an annular groove on the sleeve and causes it to follow the reciprocations of the slide. The sleeve 17 slides on the spool spindle 16 and rotates it by means of pins 18 which pass through a member 19 secured on the spindle. The thread guide-bar 26 is reciprocated by the cam wheel 20 by means of a bell-crank lever 22 pivoted at 23 and a slide 25 which can slide at one end on a fixed bar 27 and to the other end of which the bar 26 is secured. A stud on the one arm of the lever 22 engages in a circumferential groove on the cam wheel, and the other arm of the lever is slotted and carries a block which can move in a slot in the slide 25. A feeler feed device and the thread guide are mounted on a screwed rod 28 on the bar 26. The shaft 3 is displaceable but a screw 6 in an annular groove in the worm 4 prevents the latter from shifting. The slide 12 may be connected to the eccentric wheel by a concentric lateral groove on the wheel instead of by a projecting rim. In the Specification as open to inspection under Sect. 91 (3) (a) it is stated that cheeses may be wound on the machines. This subject-matter does not appear in the Specification as accepted.

Abstract: 173,686. Bonham, H. Dec. 10, 1920. Addition to 160,685. Cylinder machines.-A machine of the kind described in the parent Specification, in which is employed a travelling impression cylinder, which is cut away for a half of its periphery, and is continuously driven in one direction by gearing as described in Specification 145,938, is modified by mounting the impression cylinder b in fixed bearings, and causing the bed c to reciprocate. The machine so modified is similar to that described in Specification 145,938, and differs from it in that no positive tripping-means is employed to trip the impression cylinder as the bed travels beneath it during the non-printing portion of the stroke of the bed. In the present machine, the cut-away part of the impression cylinder passes over the forme on the bed as it returns after effecting the printing. The bed c is reciprocated by an oscillating lever l fitted at its upper ends with rollers l<2> arranged between a recessed guide l<3> on the bed. The cylinder b is fitted with two gear-wheels geared to racks on the bed so as to rotate in opposite directions. These gear-wheels are arranged to drive the cylinder by clutches which rotate the cylinder b only in a clockwise direction, one clutch taking up the drive as the other one is free. The sheets are fed from a board m and delivered by tapes n to a receiver a'.

A turbodrill comprising a tubular housing 40, 64 and a turbine assembly which rotates therein, the bearing arrangements including rotating and stationary sleeves 60, 66 between which a liquid leakage path is provided, is characterized by the provision of laterally extending deflector means 30 shaped at 32 to re-direct the liquid discharged downwardly from the liquid leakage path into an upward direction. Thrust bearings 42, 44 may also be provided. The liquid normally escapes from the leakage path in a downwardly directed high velocity curtain which, in the absence of a deflector, seriously erodes the components in its path, including the rock bit 19 itself. The downwardly moving curtain also interferes with the upward movement of the liquid, i.e., the drilling fluid, and the consequent removal of the cuttings from the bore. As shown, the deflector 30, is a metal ring with a hardened surface, an annular groove of 60 degrees angle providing the direction-reversing contour. The ring is held on the rotary shaft 41 by grub screws 34, which may be supplemented by a key or the like which engages an annular recess in the shaft. In a modification, the ring 30 is made of rubber or plastic which is stretched to pass over and grip the shaft 41.

Abstract: 1417922 Die casting apparatus COATS & CLARK Inc 24 July 1973 [25 July 1972] 35300/73 Heading B3F A die casting apparatus comprises a first die plate 20 having a cavity 22 therein, a second die plate 16 having an opening 26 therethrough, and a third die plate 18 having a recess 32 therein, the die plate 16 being fixed in position and the die plates 20 and 18 being movable relative to the plate 16. Molten metal is introduced into the mould cavity 22 via a nozzle 40, runner 41, recess 32 and the opening 26, the metal in the cavity 22 forming the cast article and the metal in the opening 26 and the recess 32 forming the gate. Movement of the plate 18 away from the plate 16 causes the gate to break away from the cast article and to be withdrawn from the opening 26 since the gate part formed in the recess 32 is held therein by a curved portion 38 of the surface defining the recess. Further movement of the plate 18 causes an ejector pin 33 to strike a fixed part of the apparatus and thus push the gate part out of the recess 32, the gate part undergoing a pivoting movement about the portion 38 as it is ejected. Movement of the plate 20 away from the plate 16 results in ejection of the cast article from the cavity 22.

Abstract: 1,200,758. Photo-electric analysis. ELTRO G.m.b.H. & CO. GES FUR STRAHLUNGSTECHNIK. Aug.3, 1967 [Aug.25, 1966], No.35632/67. Heading G1A. The dispersive or diffractive effects of a medium is determined by observing the effect upon a diffraction pattern generated by a grating when the medium is interposed between the grating and the illuminating source of monochromatic coherent light. In Fig. 2 light from a laser passes through a medium 2, such as the atmosphere, where it is rendered largely incoherent to illuminate a diffraction grating 5. The diffraction pattern generated by the grating is viewed periodically with the aid of a rotating mirror 6, by a telescope 10 containing a photo-multiplier 16. Different orders of the pattern are selected by rotating the telescope about an axis through the grating. In alternate periods the telescope receives a reference beam via mirror 4 and glass fibre light guide 13. The two beams are balanced by a wedge 19 variably positioned in the reference beam according to the output of the photomultiplier. The position of the wedge indicates the intensity of that part of the diffraction between being viewed. In another embodiment Fig. 1 (not shown) there is no reference beam.
