Heading A2C. A device for combining two streams of cigarettes comprises a conveyer provided with cigarette receiving compartments, two distributer drums on which two streams of cigarettes are received and which feed the cigarettes one by one into successive compartments of the conveyer and means for displacing one row of cigarettes lengthwise inside the compartments so as to align both rows in a direction at right angles to their axes for collection as a single stream. As shown in Figs. 1 and 2, the cigarettes are fed from conveyers 15, 15<SP>1</SP> to distributer drums 1, 1<SP>1</SP> having compartments 3, 3<SP>1</SP>. The compartments 3, 3<SP>1</SP> each co-operate with alternative compartments formed by ridges 6 in an endless conveyer 5, the compartments 3, 3<SP>1</SP> being offset with respect to each other so that cigarettes from each stream are fed into alternate compartments of the conveyer 5. The cigarettes are held in the conveyer 5 compartments by a plate 8 and moved into a single stream by a conveyer 7 having a transverse component of movement and a longitudinal component of movement equal to the speed of the conveyer 5. The aligned cigarettes pass under guides 13, 14 to a delivery belt 16. Instead of the conveyer 7 the cigarettes may be aligned by air pressure acting along the compartments of the conveyer 5 (Figs. 3 and 4, not shown).

Gases, dust and volatilized alkalis leave the kiln as a stream having a temperature of at least 1800‹ F. The stream preheats raw material being fed to the kiln from a hopper 10 through a particle suspension type preheater 5 (which may be a cylindrical tower and/or a plurality of cyclone separators). From a hood 2, a portion of the stream leaving the kiln 1 is by-passed away from the preheater 5 through a separator 30. Water is sprayed into the separator 30 at 32 in sufficient quantity to lower the temperature to below 600‹ F. to obtain rapid freezing of volatilized alkalis to particles smaller than 10- 20 microns. From the separator 30, particles larger than 10-20 microns are returned to the kiln and the by-passed stream passes to a fine dust collector 22 where the alkali particles and dust particles smaller than 10-20 microns are separated. The main stream of gases &c. from the hood 2 passes upwardly through the preheater 5 and a cyclone dust collector 15, being drawn on by a fan 20 to the fine dust collector 22.

Abstract: 1440085 Mechanical milking process F HAPPEL 17 Sept 1973 [3 Oct 1972] 43528/73 Heading A1M A method for the milk flow dependent termination of a mechanical milking process wherein a pressure massage is produced by a periodic change between pressure and atmosphere in the inner chamber of the teat cup, a constant milk line suction being stopped temporarily before the start of the pressure massage and recommencing before the massage is finished. The process is automatically stopped when the milk flow drops below a predetermined level and the teat cups are. held in place by an external face, to avoid damaging the udder. A preferred method involves stopping the milking process and after a predeterminable time starting it again so that complete milking is achieved. Preferably, the external force, which may assist in the pressure massage is produced by pressure differences in spaces outside the teat cup inner space.

A self-centering ball joint assembly for use as a compression - or tension-loaded mounting for the steerable wheels of vehicles, comprises a housing having a part spherical internal bearing surface and enclosing a composite ball head of segmental bearing elements surrounding a conical projection on a semispherical stud head. In Fig. 1, a ball joint for compression loading has a housing composed of upper and lower parts 16 and 18, with flanges 21 and 22 secured together at 23, and defines a part spherical inner bearing surface 17. The enclosed stud head comprises a shank 26 which can swing and rotate about centre C, a semispherical portion 27 having a flat clutch face 29, and a conical projection 30 extending from this face the projection supports three segmental bearing elements 31, which together form a semi-spherical bearing face complementary to the bearing surface 17 of the housing. When loaded the joint has a clearance space 28 between the semi-spherical portion of the stud head and the lower face of the housing, and a space S above the clutch face, so that the loading force causes the bearing elements to be wedged radially outwards into bearing engagement with the bearing surface 17. Fig. 8 illustrates a ball joint for tension loading, the conical portion 67 being adjacent to rather than remote from the shank 65, and the segmental bearing elements 69 bearing on the semi-spherical lower face 60 of the housing. The ball joints are preferably pre-loaded by suitable means, so that the members are retained in their loaded positions. Such means include: 1) a flat ring with inwardly radially projecting resilient fingers, the ring being secured between the flanges of the housing parts and ithe fingers being flexibly deformed into engagement with, and to exert a load upon the stud head; 2) a cylindrical thrust member with a threaded outer surface which engages threads in one end of the housing, and having a recessed seat which is either brought to bear upon the stud head by manual adjustment or is maintained in such a position automatically by rotational force provided by a tensioned helical spring; 3) a resilient cup situated in the space between the stud head and housing and secured by an integral flange which is gripped between the flanges of the housing pants; 4) a cup member which is caused to bear upon the stud head either by a resilient and or a spring, compressed between the said member and a housing closure cap. In the ball joint of Fig. 11, the thrust member carries a peripheral seal 40 which engages the bore of the housing to retain lubricant within the housing.
