Title: Ink agitator device
IPC: B41F31/03
Filed: 1961-12-12
Abstract: 923,262. Inking-apparatus. BALDWIN-GEGENHEIMER CORPORATION. Dec. 12, 1961 [April 5, 1961], No. 44540/61. Class 100 (2). [Also in Group XXIV] An agitator device for the ink fountain 12 of a printing press comprises an elongated housing 14 supported at each end by brackets 16 which are pivoted at 19 so as to vary the rotational disposition of said housing relative to said roller and clamped to the press frame by screws 32, an endless movable conveyer 48 mounted in said housing and adapted to cause a mixer head 42 supporting a conical mixer member 34 on a rotatable shaft 38 to slide longitudinally in said frame, means for reversing the direction of movement of said head in the housing 42, and means for rotating the shaft 38 simultaneously with the movement of said head by the conveyer 48. The conveyer chain 48 is driven by a motor 52 and is connected to the head 42 by a pin 60 fixed to the chain and accommodated in a block 62 slidably mounted in a transverse slot 64 in the bead 42. As the chain is driven around sprockets 50 and 58 the pin 60 urges the block 62 and thus the head 42 in a direction parallel to the longitudinal axis of the housing 14, causing head 42 to travel back and forth. The mixer member 34 is fixed to one end of the shaft 38 which is connected detachably, for cleaning or replacement purposes, by a spring-lock coupling 39, Fig. 8 (not shown), to a drive-shaft 40 supported rotatably by bearing rings 66 and 68 in the head 42. The rear plate 46 of the housing 14 supports a rack the downwardly disposed teeth 71, Fig. 3, of which engage a pinion 70 fixed on the shaft 40. The teeth 71 and the pinion 70 are so constructed that when the head moves in the direction A the mixer 34 is simultaneously rotated anti-clockwise so as to prevent the build up of ink at the ends of the fountain 12. The head 42 is supported and guided for longitudinal movement by a keyway 76 therein which engages an elongated track 74 on a front plate 44 of the housing 14. In-an alternative embodiment, Figs. 5-7 (not shown), cam means are provided at each end of the conveyer chain to cause the engagement and disengagement of the pin 60 and the cam means are adjustable in position to alter the length of reciprocal travel of the head and the mixer 34.

Title: Polyolefine compositions
Inventor: CLARK KEITH JASPER
IPC: C08L23/20
Filed: 1964-11-05
Abstract: A polymeric composition made up predominantly from polymerized units of a first component which is 4-methyl hexene-1, 5-methyl hexene-1, or 5,5-dimethyl hexene-1, having a melt flow index of from 0.01 to 1000 and containing dispersed throughout the composition up to 5% by weight of polymerized units of a second component which is an aliphatic or cycloaliphatic 1-olefine, the homopolymer of which melts above 275 DEG  C., and the polymerized units of the second component being present in a quantity and dispersed to a degree such that the polymeric composition has a mean spherulite size when quench compressed moulded of not more than 5 microns, is made by sequentially polymerizing monomers selected from both of the components in the presence of a stereospecific catalyst.  Suitable second components are 3-methyl pentene-1, 4,4-dimethyl pentene-1, 3-methyl butene-1, 3-methyl hexene-1, 3-ethyl pentene-1, and vinylcyclohexane. The components may be polymerized in any order, or together when the monomers polymerize at different rates, but it is preferred to polymerize the second component in a separate preliminary stage.  Minor amounts of a third component may also be polymerized, e.g. hexene-1, or decene-1.  The preferred catalyst is TiCl3 activated with an aluminium trialkyl or aluminium alkyl chloride. The TiCl3 is generally obtained by reacting TiCl4 with an aluminium alkyl sesquichloride.  Hydrogen may be present.  The polymers are recovered by conventional "low-pressure" methods.

Latching means 8a, 8b, are provided for engaging the projecting formations to impart an initial lateral diverting movement to a selected slide member, and stationary guide means 9a, 9b, are associated with the upper run of the conveyer for engagement with the projecting formation 5 of a diverted slide member to complete its lateral movement. Stationary guide means (not shown) are associated with the return run of the conveyer for engagement with the projecting formation 5 of a diverted slide member for return- . ing the latter to a central position. The latching means for movement of the slide members in one lateral direction comprises a lever 8a, 8b, pivoted about an axis 11a, 116, substantially vertical to the plane of the adjacent run of the conveyer, one arm of the lever being movable between two stable positions in which it respectively obstructs or passes the projecting formations on the slide members, the lever being urged towards one of its stable positions by a spring 15, providing two positions of stability, the other arm of the lever being acted on by a push-pull solenoid arrangement 20 actuated in response to current pulses, generated at defined instants in relation to the conveyer movement.

Title: Improvements in or relating to methods of forming strips from tobacco leaves for wrapping cigars and machines for the application of said methods
IPC: A24C1/04
Filed: 1964-11-19
Abstract: 1,086,688. Cigar making machines. SERVICE D'EXPLOITATION INDUSTRIELLE DES TABACS ET DES ALLUMETTES. Nov. 19, 1964 [Nov. 20, 1963; Feb. 4, 1964], No. 47058/64. Heading A2C. A process for forming strips from tobacco leaves for wrapping cigars comprises the steps of spreading out the leaves, cutting the outspread parenchyma of the leaves into a plurality of parallel strips, cutting each strip transversely at the beginning and end of the leaf and before and after each hole or tear of the leaf so as to obtain transversely cut sections of the requisite length to form a cigar wrapping and joining the sections of insufficient length by means of a small overlap to the following section of the same strip so as to give the new section a length which is at least equal to the requisite length. The leaves are laid one by one on a casing 8 with the stems being placed within the groove of plates 4 fastened to an endless chain 3. The leaf is conveyed over a suction box 1, progressively opened out by suction holes 50 in the box and maintained in axial alignment with the groove in the plate 4, by presser devices 5. The leaf is then transferred by suction to a drum 9 upon which it is cut into six strips, three on each side of the rib, by circular cutters 12. A scraper 13 removes the rib after cutting. The cut strips are scanned by a plurality of pivotable mirrors 15 cooperating with photo-electric cells 14. The strips pass under transverse cutters 16 which are normally operated to cut the strips after a pre-determined length has passed. The strips are removed from the drum 9 by six separately driven suction conveyers 25 running around rollers on shafts 28, 29. If a strip is defective this is sensed by the appropriate photo-electric cell 14, which is connected in a circuit which controls the appropriate cutter 16 to sever the strip immediately before and after the defective portion. The drive of the appropriate conveyer 25 is stopped for a sufficient time to allow the severed strips to be gummed by a device 31 and overlapped. A presser finger 32 is also operated to seal the overlap joint.

The film may be moved relatively to the reading head to take into consideration manifold pressure and desired engine speed, and, in the case where the film is placed around the periphery of a transparent light containing drum the former is achieved by rotating the drum by means of a Bourdon tube connected to the manifold and the latter by moving the detector along the drum. Control is effected through a pulse width converting circuit. The introduction of a further variable e.g. engine temperature may be effected by controlling the intensity of the light applied to the film and a transistor control circuit containing a thermistor responsive to engine temperature. This may be used to improve cold start.
