A machine for cutting frozen butter comprises a fixed hollow casing 3, an open topped cylindrical container 5 mounted for rotation about a vertical axis within the casing 3, apertured cutting means 16 secured to and forming the bottom of the container 5 for rotation therewith and a fixed blade 15 mounted within the container 5 to restrict rotation of the butter 9 in operation, the arrangement being such that butter 9 is fed through a hopper 13 and under its own weight against the rotary cutter 16 and cut fragments pass through the apertures therein. The cutting means 16 is detachable, e.g. by a keyhole slot attachment, and as shown comprises a disc with radial slits each having one side formed as a cutting edge. Alternatively the cutting disc may be formed with holes and may have either a smooth or a rasp-like face in contact with the butter. In another embodiment (Fig. 8 not shown), the cutting means has a conical rather than disc-like form. The cutting means 16 carries a blade 21 which forces the cut butter through an apertured plate 18 releasably mounted therebeneath in a discharge spout 17.

In a system in which pumps supply concentrated weighting agent and dilutant respectively to a treatment bath through which fibre material is passed and the ratio of the supplies is automatically controlled in dependence on a measurement of weighting agent absorbed by the fibre as claimed in the parent Specification, the swept volumes of the pumps are controlled and the pumps are driven at speeds proportional to the speed of the fibre. As in the parent Specification, dressing solution and diluting liquid are supplied by pumps to a container feeding a bath through which fibre threads are drawn continuously, the two supplies being automatically varied in opposite senses in response to a measurement of the amount of dressing absorbed to keep the latter constant, and in the same sense in response to the level of liquid in the container to keep the latter between predetermined limits. In the present Specification the pump drive is mechanically coupled to squeeze rollers engaging the fibre as it leaves the bath and the automatic control of pump delivery is by reversible servomotors controlling the length of the stroke of each pump.

Heading C2C. [Also in Division C7] Water-dilutable salts of amino-triazine carboxylic acids are obtained by (a) reacting an etherified amino-triazine formaldehyde condensation product, which contains at least one mole of volatile alcohol groups as a component of the ether structure, with an acyclic aliphatic monohydroxycarboxylic acid ester by heating, and (b) saponifying the reaction product in an alkaline medium. The saponification product may subsequently be (c) subjected to an azeotropic distillation for separation of the water, with the help of an azeotropic entraining agent under vacuum and with heating, (d) the distillation residue, by the addition of an acid which is preferably organic and which may be dissolved in an organic solvent, may be converted into the free resin carboxylic acid, wherein the added acid is of such amount that it neutralizes most of the alkali but without any remaining surplus of acid, (e) the resulting salt separated, and (f) the resin carboxylic acid converted into watersoluble products by the addition of ammonia and/or a strong organic base which, in 50% by wt. aq. solution, has a pH of at least 9. Reaction step (a) above is suitably carried out in the presence of a catalyst at 100-180‹ C. The etherified amino-triazine formaldehyde condensation products employed as starting materials are the etherified reaction products of amino-triazines of the formulµ wherein R is an alkyl, allyl, cycloalkyl or aryl group, with formaldehyde, preferably those which contain 4-6 moles formaldehyde per mole of melamine and at least 60% of the methylol groups are etherified with monovalent alcohols including at least one mole of a volatile alcohol; other preferred starting materials are the benzoguanamino-methylol ethers of monovalent alcohols which include 3-4 moles of formaldehyde groups. The ester starting materials are preferably hydroxycarboxylic acid esters of mono-, di- and tri-hydric alcohols with 1-6 carbon atoms where the hydroxycarboxylic acids have 2 to 18 carbon atoms and the hydroxyl groups are in primary or secondary positions. The molecular weights of the products may be increased, e.g. by heating in an acid medium during or after the re-etherification with the hydroxycarboxylic acid ester until the product has an acid number between 30 and 160. The preparation of the starting materials is described by methylolating and subsequently etherifying an appropriate amino-triazine derivative.
