Abstract: 1,268,123. Packaging; endless conveyers for capsules. ELI LILLY & CO. 14 Nov., 1969 [15 Nov., 1968], No. 55958/69. Headings B8A and B8C. Capsule handling apparatus for successively conveying a capsule having body and cap portions 22B, 22A through capsule-feed, -separating, -filling, -assembling, and -ejection stations, comprises an endless chain conveyer 20 guided on sprockets 26-31 and provided with a plurality of pairs of complementary capsule holders 32, 39 for carrying the capsule body and cap portions respectively, and a cam track 43 for moving the cap holders 39 into and out of alignment with the body holders 32 in a predetermined sequence as the holders are carried through the various stations. The body portion holders 32 are formed by the connecting pins of the conveyer chain links and are provided with body support shoulders. Each cap holder 39 is formed by a bush carried on the free end of an offset arm 38 whose other end is pivoted on a chain link connecting pin so that the cap holder may be pivoted into and out of alignment with the body holder constituted by the adjacent connecting pin. Alignment or misalignment of the pairs of capsule holders is effected by engagement of the cap portion holders in a groove 43B in a cam track 43. In operation, empty assembled capsules 22 are fed down a tube 45 from a turret feed station (not shown) at sprocket 26 into each aligned pair of holders. The aligned holders and the empty capsules are carried by the chain to a separating station 46 where vacuum is applied to the base of the body portion holders, Fig. 6 (not shown), to separate the body portions from the cap portions. The complementary cap and body portion holders are then moved out of alignment as they are conveyed to a filling station (not shown) at sprocket 27. At the filling station the body portions are filled with a predetermined amount of a powder by a pick-up 49 associated with rotating turret (not shown) synchronized to the sprocket 27. The cap holders are then brought back into alignment with the body portion holders as they move from the feed station over a tensioning sprocket 28. As the aligned holders are carried around the sprocket 29, they are carried through assembling and ejecting stations, Figs. 8-10 (not shown), wherein camactuated reciprocating fingers, which are carried to synchronized turrets above and below the chain run, firstly raise the filled body portions of the capsules into engagement with the cap portions, and secondly lift the thus assembled capsules out of each pair of holders, an air blast 52 dislodging the capsules from the fingers, Fig. 10, into a collector (not shown). The emptied holders are then misaligned and carried through a purging station at sprocket 31 where reciprocating fingers 54, Fig. 11 (not shown), remove any remaining jammed capsule portions from the misaligned holders. The cycle then recommences.

Filed: 1970-12-21
Abstract: 1340206 Feeding sheets XEROX CORP 21 Dec 1970 [31 Dec 1969] 60543/70 Heading B8R Sheet feeding apparatus includes a gripper mechanism to feed sheets along a path, first sheet contacting means, e.g. a roller 103 in the feed path, and second sheet contacting means, e.g. a roller 101 adapted for movement from a first inoperative position to a second operative position in the feed path and in contact with said first means to exert a drag force on a sheet fed therebetween by said gripper mechanism, so that in operation sheets improperly gripped by the gripper mechanism are pulled from the mechanism. Copy sheets in a xerographic copier are fed into the slot 44 of a gripper rod 46 and in so doing actuate a switch 40 which actuates cams 47, 48, after a time lag, to pivot gripper rod 46 to grip the sheet between the rod and a spring member 49. This gripper mechanism is mounted on chains 56 which move the sheet over the feed path, the gripper mechanism actuating a switch 110 which causes a solenoid to depress roller 101 into contact with the sheet passing over the roller 103, these rollers being rotatable on their shafts against the frictional resistance of spring washers (138), Fig. 3 (not shown), adjustable by bolts (142). Switch 110 is subsequently released from its latch 120 by a gripper actuated lever and chain 122. Switch 40 stops the machine when it senses a sheet pulled from the gripper mechanism.

Abstract: 1368310 Hydraulic control circuits TATRA NARODNI PODNIK 30 Dec 1971 [30 Dec 1970] 60786/71 Heading B7H An hydraulic control circuit for controlling the steering system S and the fan motors 8, 8<SP>1</SP> of a vehicle comprises a source of primary fluid 1, conduit means including a valve assembly 4 having a by-pass means for selectively supplying fluid to only the steering system or to both that and the fan motors, a first pump 2 for supplying primary fluid to the valve assembly, the first pump having hydraulic displacement adjusting means, a source of secondary fluid 6, conduit means including a thermo-valve 3 responsive to a predetermined heat level to allow delivery of secondary fluid to both the adjusting means and the by-pass means to permit flow of primary fluid to both the steering and fan systems. Primary fluid passes from pump 2 via line 57 to an inlet A of the assembly 4 and thence via a groove 24, bores 17, 16 and 18, a groove 25 and a bore 35 to a chamber 29. Chamber 29 communicates via axial bores 33 in a sleeve valve member 15<SP>1</SP> with a line 62 connected to the steering system S. If the primary fluid pressure exceeds a predetermined value valve member 15<SP>1</SP> moves to allow fluid to pass to an exhaust line 61. The thermo valve 3 normally allows secondary fluid to pass from a secondary pump 7 via line 56 to a return line 51. On sensing a predetermined heat increase by an element 46 a diaphragm 45 moves a hollow piston valve member 48 to close the return line and fluid is supplied to a line 54. This line joins a line 58 connected to a chamber 10a of the valve assembly 4 and the secondary fluid causes a piston 20 in the chamber to move a sleeve valve member 13 in which the grooves 24, 25 are formed. Groove 24 then connects the inlet A with line 62 via the bores 17, 16, 18 and a passage 36, and connects inlet A to the fan motor supply lines 64, 65.

Title: Electrically controlled photographic shutter
IPC: G03B9/10
Filed: 1969-12-29
Abstract: 1291869 Shutter timing control CANON K K 29 Dec 1969 [28 Dec 1968 5 Dec 1969 18 Dec 1969] 63052/69 Heading G2A A camera shutter having an electrical timing circuit for controlling the exposure has a further independent mechanical timer, with means for bringing the independent timer into operation if the electrical timing circuit does not function. The arrangement may be adapted to either focal plane or inter-lens shutters. Fig.3(a) shows a focal plane shutter in the tensioned position, the front and rear blinds of the shutter being operated by pawl discs 20,19, which are latched in the tensioned position by respective pawls 22, 21. When the shutter release button is pressed, a main switch (SM, Fig.2 not shown) is closed, and pawl 22 is pivoted clockwise, so that disc 20 is released, and the front blind begins to run. At the same time pawl 22 opens a switch S 1  which initiates the operation of a timing circuit. After a predetermined time an electromagnet M 1  is energised, attracting an armature 25 and so causing pawl 21 to pivot out of latching engagement with disc 19. Thus disc 19, and hence the rear blind, can now run down to terminate the exposure Fig.3(b), (not shown). A further electromagnet M 2  in the circuit is continuously energised, so that a further armature is held against it all the time. A further pair of levers 29, 33 is thus drawn clear from the remainder of the mechanism, and therefore takes no part in the operation so far described. If the user has forgotten to insert any batteries, or they have become exhausted, neither electromagnet M 1  or M 2  is energised. Depressing the shutter release will still unlatch pawl 22 from disc 20, allowing the front blind to run, but magnet M 1  in this case will not cause pawl 21 to release disc 19. Since magnet M 2  is not now energised, a spring 37 draws lever 29 against a stop 38. In this position, one end 33' of a lever 33 pivoted on lever 29 extends into the path of a pin 20" on disc 20, which is initially in the position shown in Fig.3(a). When disc 20 has rotated sufficiently, pin 20" strikes the lever end 33', as shown in Fig.3(d). This pivots lever 33 clockwise, so that its other end strikes a pin 28 on pawl 21. Thus pawl 21 is pivoted out of engagement with disc 19, which can now run down as before to terminate the exposure. Fig.5 (not shown) is a similar type of mechanism adapted for use with a pivoted blade shutter.
