Title: Anti-coccidial compositions comprising quinolinium and isoquinolinium salts
IPC: C07D403/06
Filed: 1960-01-22
Abstract: Pyrimidylmethyl-quinoline and -isoquinoline derivatives of the general formulae <FORM:0933041/IV(a)/1> where R and R1 are lower (C1-5) alkyl groups, X is an anion, n is 0, 1, 2 or 3 and b and c are positive numbers such that b moles of cation are neutralized by c moles of X, may be prepared by reacting together an appropriately substituted quinoline or isoquinoline with a 2-lower alkyl-4-amino-5-bromo- or chloro-methyl pyrimidine dihydrohalide or an ester of the corresponding 5-hydroxymethyl pyrimidine, e.g. in an organic solvent.  By this method there may be prepared the 1-(2-ethyl-4-amino-5-pyrimidyl methyl) and 1-(2-methyl-4-amino-5-pyrimidyl methyl) derivatives of 2-methyl-, 4-methyl-, 6-methyl- and 7-methyl quinolinium, 3-methyl-isoquinolinium and isoquinolium bromide hydrobromides and 1-(2-methyl-4-amino-5-pyrimidyl methyl) quinolinium bromide hydrobromide.  2-Lower alkyl-4-amino-5-halomethyl pyrimidines may be prepared by the following reaction sequence in which specific examples describe a reaction employing n-butyramidine hydrochloride as starting material and naming isobutyramidine, n-amylamidine and n-hexylamidine as alternatives: n-Butyramidine hydrochloride is reacted with ethoxymethylenemalononitrile in sodium/ethanol to give 2-n-propyl- 4-amino- 5-cyanopyrimidine which is reduced in the presence of ammonia and a nickel catalyst to give 2-n-propyl-4-amino-5-aminomethylpyrimidine, the dihydrochloride of which is treated in water with sodium nitrite to give 2-n-propyl-4-amino-5-hydroxymethyl pyrimidine which, on treatment with acetic acid saturated with hydrogen bromide, gives 2-n-propyl-4-amino-5-bromomethyl pyrimidine dihydrobromide, the alternative starting materials giving the corresponding 2-isopropyl-, 2-n-butyl- and 2-n-amyl compounds respectively.ALSO:Anti-coccidial compositions comprise an inert edible solid carrier in which is dispersed a quaternary salt having the formula <FORM:0933041/VI/1> or <FORM:0933041/VI/2> wherein R and R1 which may be the same or different are lower (C1-5) alkyl groups, X is an anion, n is 0, 1, 2 or 3 and b and c are positive numbers such that b mols. of cation are neutralized by c mols. of anion X.  The anion may be that of an inorganic acid, e.g. the chloride, bromide, iodide, nitrate, sulphate, or phosphate ion, or of an organic acid, e.g. the citrate, tartrate, acetate, picrate, stearate, succinate, benzoate, phthalate, phenoxyacetate, embonate, abietate, 2-naphthalene sulphonate, ethylene, diamine tetra-acetate, or it may be a polymer e.g. a polyphosphate or a polystyrene sulphonate.  The compositions may be in the form of a feedstuff or feed supplement.

[Class 83 (iii).] A lathe or like machine has gearing which can be selectively actuated to connect either of two shafts with a sleeve which drives the spindle and preferably can be braked ; the sleeve being loose on a third shaft which is meshed with one of the two shafts which is driven through a pair of pick-off gears, and meshed with the other shaft through a pair of pick-off gears. The hollow spindle 12, Fig. 2, mounted in ball and roller bearings in the headstock is rotated by a worm 14 carried by a sleeve 15 freely rotatable about a transverse shaft 16, the latter is connected at one end by a pick-off gear pair 19 to a further transverse shaft 17 and at its other end, by a permanent gear pair 21 to a third transverse shaft 18 ; a gear 24 fixed to the sleeve 15 is permanently in mesh with gears 22, 23 carried by the shafts 17, 18 respectively, and associated with friction clutches 25, 26 so that they may be selectively fixed to the shafts. A fourth transverse shaft connected by a pick-off gear pair 41 to the shaft 18 is driven by a self-contained electric motor (not shown) through a friction coupling 43 adapted to slip on overload. The clutches 26, 25 are actuated by a lever 29 pivoted at 30, Fig. 3, linkage 32, 33 transferring motion from a hand or automatically rotated spindle 34 ; when the clutch 26 is engaged the drive passes from the motor through gear-pairs 41 and 23, 24 to the worm and spindle the wheel 22 being loose on its shaft, when, however, clutch 25 is engaged the drive passes through the gear pairs 41, 21, 19 and 22, 24 to the worm and spindle the wheel 23 running loose.

Abstract: 1,222,975. Shearing. G. I. PSHENICHNY, Y. Z. CHECHELJUK, M. A. AFANASIEV, and N. N. KHMARA. 22 Feb., 1968, No. 3240/68. Heading B3W. An automatic line for cutting steel strip into plates for transformers comprises a first rotatably mounted shear 10 for cutting plates with two acute corners, a feed device 12 for transferring blanks but by shear 10 to a second shear 11 for trimming off one of the acute corners which has an upper and a lower blade, 27, 26 each of which is in two sections spaced to allow an electromagnetic member 28 of the feed device to pass through the shear to receive the plates cut by the shear 10 and carry the plates first to the shear 11 and then to a device (13) (Fig. 5, not shown) for removing finished plates from the line. In operation, strip is first fed by hand from an unwinding device (1) (Fig. 1, not shown) through a tensioning device 5 to a feed  mechanism (6) comprising two gripper carriages (7) (Figs. 2 and 3) reciprocating in alternate feed and return strokes. The drive (3) of the  device (1) and the hydraulically-actuated rack and pinion drive (8) of the feed mechanism (6) are then switched on. One carriage (7) feeds the strip to the shear 10 which is disposed at 45 degrees to the feed direction of the strip. When the carriage reaches an adjustable stop (9) adjacent the shear 10 the drive (8) is stopped and the tensioning device (5) and the shear 10 are actuated. Whilst the other carriage executes a feed stroke the shear 10 is rotated through 90 degrees so that the next cut will produce a plate of regular trapezium shape. After the cut the feed device 12 is moved by hydraulicallyactuated rack and pinion drive 33, until it abuts a retractable stop 32, to feed the plate to the shear 11 which trims off the leading acute corner. The stop 32 is then retracted and the feed device 12 carries the trimmed plate to the device 13 which comprises two groups of electromagnetics mounted on a carriage reciprocable transversely of the automatic shearing line to deposit finished alternately in bins disposed one on either side of the line. A switch (4) in a pit adjacent the unwinding device (1) stops the drive of the device when a reserve of strip has formed in the pit. The spacing between side guide rollers 24 for the strip is adjustable.
