Abstract: 1,055,021. Variable speed gear. R. RUFFER. March 25, 1964 [March 26, 1963], No. 12665/64. Addition to 014,965. Heading F2D. [Also in Division G1] In a variable speed ratchet gear of the kind described in the parent Specification wherein a driving rod a of variable effective length is carried by a bracket 7 fast with a driving shaft 1 and coacts with a lever b connected through a one-way clutch 11 to an output shaft 2, the effective length of the rod a is automatically adjusted once during each revolution of the driving shaft 1 by a lever 30 controlled by a correction gauge 36. The rod a is held in an adjusted position in the bracket 7 by a spring pressed detent 24 which is released by a lever 26 when a roller 28 thereon engages a cam 29. The cam 29 is positioned so that the detent releases the rod a as its operative end approaches the lever 30 and the detent is re-engaged when the rod a is perpendicular to the lever 30. The lover 30 is one arm of a two-armed lever 30, 33 pivoted at 32 and the other arm 33 is held against a magnet 41 fast with the upturned end 35 of a rod 34 suspended by leaf springs 39. The correction gauge 36 comprises a bellows filled with a comparison gas to provide volumetric correction and one end of the bellows is fixed to the rod 34 whilst the other end is fixed to a casing 49. An increase in the volume of the gas causes the lever 30 to rotate clockwise and thus reduce the speed ratio of the gear. As shown an arm 8 fast with the rod a prevents rapid initial acceleration of the lever b. The lever b is retained in the rotated position until a projection 48 on the bracket 7 engages a lever 47 fast with a toothed sector 46 which meshes a toothed sector 43 fast with the lever b to rotate the latter back to its initial position determined by a stop 3. In Figs. 2 and 3 (not shown) the gear is arranged to correct the counting mechanism of a bellows type gas meter.

Abstract: 1,229,843. Spinneret for conjugate filaments. KANEGAFUCHI BOSEKI K.K. 11 March, 1968 [15 March, 1967; 22 Nov., 1967; 20 Dec., 1967; 22 Dec., 1967 (2); 29 Dec., 1967; 19 Jan., 1968; 13 Feb., 1968], No. 19517/70. Divided out of 1,229,841. Heading B5B. A spinneret for multi-layer conjugate filaments comprises (i) means for supplying a plurality of spinning materials, (ii) a spinneret plate provided with at least one spinning orifice, and (iii) at least one layer-multiplying mixer for subjecting a plurality of the spinning materials to separation and joining out of phase (i.e. in different planes), the mixer being interposed between the supply means and the spinneret plate; the mixer comprises at least one distributing plate having formed therein reservoirs and connecting passages in which the streams of spinning materials are separated and joined out of phase at least twice. Typical flow schemes are shown in Figs. 16 and 17. Fig. 9 shows how joining and separation out of phase results in layer-multiplication. A large number of embodiments of the spinneret are described, of which Figs. 18 and 19 show a simple form. Two spinning materials in reservoirs R 11  and R 12  are joined in channels 13, pass together down ducts 14 and are separated in a direction perpendicular to the joining direction through channels 15 and 16 into reservoirs R 21  and R 22 , the process being repeated until the spinneret plate 100 is reached and multi-layer filaments are extruded from orifices 105. For ease of construction in the case of more complex spinnerets, the layer-multiplying mixer may be assembled from a stack of distributing plates D 10 , D 20 , D 30  &c. (see Fig. 28) each of which is substantially identical and has reservoirs, channels and ducts formed in it as shown, the reservoirs and channels being engraved on the surfaces of the plates, and the stack together with the spinneret plate may be enclosed in an outer casing. The spinneret may be of rectangular cross-section, as those above, or cylindrical with concentric annular reservoirs and radial channels (see Figs. 59 and 61). In other embodiments, the layer-multiplied materials are further bonded with at least one more stream of spinning material, which may be single-component, mixed, or layer-multiplied, just before the spinneret plate. Thus Fig. 77 shows a cylindrical spinneret in which layer-multiplying is performed around a central passage 300 which conveys a stream of material to be bonded in channels 103 with the layer-multiplied material before extrusion. Alternatively the layermultiplying mixer may be connected in series with at least one other mixer, which may be conventional or layer-multiplying.

A method of inhibiting the growth of vegetation comprises applying to soil or plants a nitraminopyridine base of formula: or a N-oxide or salt of said base, where X is 1, 2 or 3; R 1  is H or a substituted or unsubstituted hydrocarbyl radical; each of R, R<SP>2</SP> and R<SP>3</SP> represents H, halogen, substituted or unsubstituted hydrocarbyl, NH 2 , NO 2 , SO 3 H, CF 3 , CCl 3 , CN, OR', SR' or COOR' where R' is H or a substituted or unsubstituted hydrocarbyl radical; other than a nitraminopyridine base of formula:  or a N-oxide or salt of such a base, where R is H or C, to C 6  alkyl, R<SP>2</SP> is Cl, Br, C 1  to C 6  alkyl or NO 2 , and R<SP>3</SP> is Cl, Br, or NO 2  but different from R<SP>2</SP>. Typical active ingredients specified are 3, 5-di Br-2-, 2, 6-di C1-4-, 5-Cl-2-, 5-Br-2-, 2-Br-4-, 2-Cl-4-, 2-Cl-5-, 3-Cl-5- and 3-No 2 - 2-nitraminopyridines. Other herbicides may be present and specified are various substituted phenoxyaliphatic acids, triazines, urea derivatives, pyridylium derivatives, acetanilides, acetamides, carbamates, uracils, substituted anilines and pyridazones.

Abstract: 1,233,642. Toothed gearing. E. SCHEUBECK. 22 April, 1969 [26 April, 1968], No. 20528/69. Heading F2Q. [Also in Division H1] A tap changer having a diverter switch and a tap selector, and generally of the type described in Specification 1,197,379, comprises for its tap selector mechanism a Maltese-cross wheel 21, two drive-rings 31, 32 and two selector contacts 14, 15 coupled to the drive rings one each respectively. The selector contacts traverse circumferentially spaced tap contacts 4, 5 &c. in a sequence; to this end, the two drive rings are rotated alternately by one sector (i.e. the angular distance between contacts 4 and 5) by a roller pin 24 which is engaged movably in a radial slot 25 of the wheel 21, which in turn is driven by a wheel 22. The selector mechanism includes a disc 27 mounted below the Maltesecross wheel on a common shaft, and having peripheral cam formations 272. The roller 24 is actuated by the disc 27 from one of the drivering grooves 35 radially outwards against the bias of a spring 26 to engage in one of the grooves 34 of the second drive ring to rotate the latter. Electrical leads 18, 19 provide connections to the selector contacts 14, 15 through ring members 16, 17, respectively. An idle motion of the disc 27 provided by a snug 30 in groove 29 may be used to maintain the tapping sequence on reverse rotation as actuated by a member 45.
