Title: Improvements in insecticides, sheep dips and the like
IPC: A01N41/04
Filed: 1924-11-12
Abstract: 246,252. McDougall & Yalding, Ltd., and Fryer, P. J. Nov. 12, 1924. Addition to 229,773. Insecticides, sheep dips, and the like.-Relates to insecticides, sheep dips, and the like containing compounds obtained from plants of the Derris family together with sulphonated oil as a vehicle, and consists in the use of sulphonated fatty oil, sperm oil, or wax in place of the sulphonated castor oil described in the parent Specification, in a method of preparing such insecticides in general, and in methods of combining them with the fungicide known as lime-sulphur. The active principles of Derris are extracted with benzene or other volatile solvent which is then distilled off and the residual extract dissolved by gentle heat in sulphonated oil or wax. In this process calcium salts of sulphonated oil may be used in solution in alcohol. These salts may be prepared by neutralizing the sulphonated oil with milk of lime or by treatment with a soluble salt such as calcium chloride. The insecticides may be diluted with water or with other spraying materials such as arsenate of lead or Bordeaux mixture. For making mixtures with lime-sulphur, a colloid such as casein is added, or a solution of sulphonated oil may be treated with a limited quantity of lime-sulphur, the precipitate filtered off, the clear liquor concentrated, and the Derris extract dissolved in this liquor to form a product to which further quantities of lime-sulphur may be added without producing a deleterious precipitate.

Abstract: 1,064,519. Drum mills. KLOCKNER-HUMBOLDT-DEUTZ A.G. July 1, 1964 [July 10, 1963], No. 27170/64. Addition to 893,162. Heading B2A. [Also in Division F2] In an oscillatory grinding mill comprising grinding drums 1, 2 and a drive comprising a shaft 14 and out-of-balance weights 15, 15' the filling of grinding bodies in the drum 1 is made so much heavier than the filling of grinding bodies in the drum 2 as to bring the axis of gravity of the mill substantially into the plate E, passing through the axis A, of the drive and perpendicular to the line connecting the centres of the drums, so that a substantially circular motion is obtained. In a modification (Fig. 3), the drums are arranged horizontally on each side of the drive axis. In another modification (Fig. 4), four grinding drums are provided one on each side of, and one above and below, the drive axis. In a further modification (Fig. 5), the plane passing through the axes of the drums is inclined to the horizontal and vertical.

Abstract: 752,623. Coke ovens. KOPPERS GES., H. Sept. 20, 1954 [Sept. 26, 1953], No. 27187/54. Classes 51(1) and 51(2). In a twin-flued regeneratively-fired coke oven, the heating flues 1, 2 are provided with calibrated rich gas nozzles 8 fed from a main 19 by flues 5 and conduits 6, 6a, and with air nozzles 12 supplied with hot air from a regenerator 20 by flues 24, the rich gas nozzles 8 being disposed between the air nozzles 12 and recirculation ports 7 connecting the flues 1 and 2.

Title: A machine for moulding butter and the like
IPC: A01J21/02
Filed: 1930-09-11
Abstract: 360,117. Cutting and moulding butter. HENRY, W., 24, Sagimor Gardens, Bloomfield, Belfast. Sept. 11, 1930, No. 27192. [Class 87 (ii).] In apparatus for moulding balls or rolls of butter for service at table, the butter is extruded by an intermittently-moving ram 47 through apertures 7 in the base of a container 9, and divided by an oscillating cutter 18 into portions, which fall into the channelled periphery 2 of a drum 1 and are carried round through an arcuate channel 10 which co-operates with the periphery 2 to give the portions the desired shape and pattern before they are discharged into a receptacle 12. The cutter moves in the intervals when the ram is at rest. Cooled water to prevent sticking may be supplied from a vessel 14 to the upper end of the channel 10. The container 9 may be surrounded by a tank containing water, brine, or ice for cooling. The moving parts are operated from a shaft 30 driven from a motor 35. The ram 47 is pushed in by a feed-bar 48 splined to move longitudinally through a housing 54 and threaded in a bevel wheel 50 which gears with a wheel 52 on a spindle 53 driven by spur, pawl and ratchet, and lever mechanism by a cam on the shaft 30. The extrusion of butter is automatically stopped as the ram approaches the bottom of the container 9, the bevel wheel 52 being moved out of gear with the wheel 50 when an abutment 67a on the bar 48 engages a lever 66. The bar 48 can then be moved by a hand-wheel 68 and a bevel wheel 51. The shaft 3 of the drum 1 is hollow, and is driven by worm gearing 39, a vertical shaft 37, and bevel gearing 41 from the shaft 30. The cutter 18 is carried by an arm 20 fixed to a shaft 21 which is oscillated within the. shaft 3 by means of worm gearing 25 and a vertical rod 24, the upper end of which is pushed downward against the pressure of a spring 27 by a cam 28 on the shaft 30.

Abstract: 1469914 Knitting machines WIRKMASCHINENBAU KARL-MARX-STADT VEB 27 June 1975 [1 July 1974] 27272/75 Heading D1C A stitch-bonding warp knitting machine comprising sliding latch needles 1, knocking- over plates 4, counter-holding pins 5 and a supporting bar 6 is characterised by the provision of a space 14 in front of the knocking- over edges of the plates 4 which space is open towards the pins 5 and allows deformation of the fibre fleece 10 to facilitate the pick up of fibres by the needles as they are withdrawn. As shown the space is bounded by flat edges of the plates 4 and by a fleece guide plate 9 and a bar 13 on a mount 12 for the plates 4. Alternatively the space may be bounded at its upper end by a second bar or by a projection on each plate 4, may be bounded only at one of its upper and lower ends, or may be composed of individual recesses wholly defined by projections on the respective plates 4. In the latter cases the spaces between plates in the vicinity of the projections are filled by lead or plastics. The counter-holding pins are adjustable in the direction away from the knocking-over plates to accommodate different thicknesses of fleece. The guide plate 9 is adjustable in the direction of the arrows or, if a second bar is provided instead, it may be adjustable horizontally, vertically or at a slant. The bar 13 may be adjustable in height or, with the plate 9, may be interchangeable with bars/plates of different sizes.
