Title: A method of establishing and maintaining asepsis in packaging machines and an apparatus for carrying out the method
IPC: B65B55/04
Filed: 1965-12-30
Abstract: 1,103,760. Packaging-machines. TEPAR A.G. 30 Dec., 1965 [27 Jan., 1965; 10 Aug., 1965; 5 Nov., 1965], No. 55263/65. Heading B8C. A method of establishing asepsis in a packaging machine of the kind in which a web 1 is formed into a tube 2, the tube being at least partially filled with a sterile filling liquid 7 and divided into closed packages 4 by means 3, and of maintaining the asepsis during interruptions of the packaging operation as well as normal operation thereof, is characterized by the filling liquid being supplied to the tube through a pipe 6, movable relative to a levelling pipe 9, or both pipes being movable relative to a third member in the tube, to shut-off the supply of filling liquid to the tube when the level of liquid in the packaging tube 2 increases by a predetermined amount above the outlet of the filling pipe 6, and to allow the filling liquid or a sterilizing agent to circulate from the supply 5 of filling liquid or sterilizing agent through the pipes 6 and 9, and back to the supply. To maintain the filling liquid 7 at a constant level 8 in the tube, the ends of the pipes 6, 9 are shaped to form a valve, illustrated by dash lines 11. A raising of the level 8 will cause a raising of the level 10 of the liquid in the levelling pipe 9 against the internal pressure maintained therein, thereby increasing the pressure. This increase actuates a pressuresensing means 18 through a conduit 17 and an open valve 15, which in turn actuates a torqueproducing member 19 which causes a relative change of position of the pipes 6, 9 by means 20 and 12. Alternatively, the third member, e.g. a valve spindle, may also be provided in the tube, the spindle being operated by the torque transmission means 20, 12 so as to adopt a desired position relative to the pipes 6, 9. If a stoppage of the packaging machine occurs, the valve 15 may be closed and a valve 14 opened to allow circulation of the filling liquid. After a long stoppage of the machine, asepsis may be re-established by circulating a sterilizing agent, e.g. hot steam or a solution of hydrogen peroxide. In the embodiment of Fig. 10 (not shown), the filling pipe (6<SP>1</SP>) is arranged inside the levelling pipe (9<SP>1</SP>). Various embodiments of valve means 11 are illustrated in Figs. 5-9 (not shown), for use with the Fig. 1 machine embodiment, and in Figs. 11-13 (not shown), for use with the Fig. 10 machine embodiment. A valve embodiment for use with semi-cylindrical side-by-side filling and levelling pipes 6 and 9 is illustrated in Figs. 3, 4 (not shown). Each valve means is capable of effecting a completely open path for the filling liquid to the tube 2, a completely closed path, and a circulatory path.

Abstract: 1293155 Fuel injectors; multiple injections ROBERT BOSCH GmbH 12 Nov 1969 [13 Nov 1968] 55265/69 Heading F1B In a fuel injection device, for a multi-cylinder I.C. engine, fuel injection pump outlets are connected by a respective supply pipe to a main injection valve for delivering a main fuel supply to one cylinder, an auxiliary pipe being branched from the supply to an auxiliary injection valve for delivery of an auxiliary fuel supply to another cylinder so that in use the main fuel injection is staggered in time relative to the auxiliary fuel injection for the same cylinder, the main and auxiliary injection valves being hydraulically separated from one another. Figs.1 to 3 (not shown) illustrate the arrangement of the main and auxiliary fuel supply pipes for four, six and eight cylinder engines, the auxiliary pipes being branched off from the main pipes to respective cylinders, the operating cycles of which are staggered according to the crank-shaft throws. The main fuel supply is delivered first through bores 31, 48, 49, Fig.4 into a pressure chamber 50, injection taking place when the pressure is high enough to lift the needle 41 off its seat. The auxiliary fuel supply passes to bores 34, 35 and at a sufficiently high pressure the plunger 36 is moved against spring 37 until arrested by its stop pin 38. The fuel displaced passes via duct 39 into the pressure chamber 27 and after lifting needle 26 flows via groove 46 and openings 47 into the cylinder. In another embodiment a common control unit (51) Fig.5 (not shown) controls the auxiliary supply. An injection pump having a speed regulator (52) and injection timer (54) is connected by a linkage to an adjustment pin (56), Fig.7 (not shown) controlling a plate (69) which controls the movement of all the auxiliary metering plungers (36). Alternatively the adjustment pin (56) may be moved hydraulically, pneumatically or electrically. In a nozzle associated with the control unit (51) the main valve 75, Fig.9 and auxiliary valve 74 have seatings angled to cause the main supply to be injected further into the cylinder whilst the auxiliary supply is injected adjacent to a sparking plug. The fuel may be injected into an engine inlet passage.

Abstract: 1,244,316. Automatic record change gramophone; radially movable transducers. PLESSEY CO. Ltd. . 13 Dec., 1968 [22 Dec., 1967], No. 58387/67. Heading G5R. An automatic record-change gramophone comprises a transducer 13 mounted on a carriage 6 freely movable along a track arm 4 and a brush member 17 having a common pivot 41 with the track arm about which the arm and brush are swung to the broken line position shown during record change. The carriage moves on jewel-pivoted rollers 7, 8 and is controlled by an arm 42 carrying the transducer leads which moves it to its outermost position on completion of record play and to its start point, dependent on record size, at commencement of play. To accommodate the, at least three revolutions of the turntable during the autochange period for record cleaning purposes the change mechanism is provided with two control cam discs 19, 20. On completion of play arm 42 actuates the change mechanism as the transducer stylus en-. ters the record run out groove, as a result cam wheel 19 is rotated by pinion 22 and via arms 29 and 30 the track arm 4 and brush 17 are lifted and via arm 32 are swung out to their broken line positions and the trolley is moved to a position on the arm 4 adjacent its pivot. A new record is lowered on to the turntable (by means not shown) and then the arm 4 and brush 17, now vertical, are raised by the lever 30, moved inwardly over the record by means of levers 32 and 34 and then lowered to a position dependent on the number of records on the turntable at which brush 17 contacts the uppermost record. At this point cam wheel 19 is stopped by a second toothless portion 26 of the wheel being moved opposite drive pinion 22 but the second cam wheel 20 brought into engagement with pinion 22 when a pin 25 thereon was engaged by pin 24 on wheel 19 continues rotating during which time the record rotates at least three times under the cleaning brush. At the end of the cleaning cycle lever 39 is moved by the control cam 20 so that pawl 40 engages in one of the grooves in pivot spindle 41 and is then actuated to move the spindle and rack 102 (via pawl 103) upwards so that the brush is lifted clear and rotated through 90 degrees to its horizontal position. The arm 42 is now operated via cam wheel 19 to move carriage 6 to a position in which the stylus is over the record start groove and lever 39 is again actuated slightly to lower the stylus on to the record. At this time cam 20 ceases to rotate but cam 19 continues, having been restarted when pin 24 thereon was engaged by a second pin 27 on cam wheel 20, until its second toothless portion 23 moves opposite the pinion 22.

Title: Improvements in and relating to photographic aperture arrangements
IPC: G03B9/07
Filed: 1968-12-12
Abstract: 1,211,264. Aperture control. RICOH K. K. Dec.12, 1968 [Dec.23, 1967], No.59065/68. Heading G2A. In an aperture-setting arrangement for a camera, the movement of the aperture-setting member is controlled by two connected cam slots 4, 5, respectively for automatic and manual setting. As shown, an aperture-setting ring 2 and cam ring 3, coupled together, are mounted respectively outside and inside the lens barrel 1. A lever 7, pivoted at 6, has a pin 8 which engages in one or the other slot, and is linked by a slit 12 at one end with a ring 10 whose rotation moves the diaphragm blades 9 directly. Lever 7 is biased in an anti-clockwise direction by a spring 13 so that the pin 8 is normally abutting the inner edge of slot 4 or 5 (position of Fig.1). An intermediate lever 16 is pivoted at 15 on a fixed support, and biased by a spring 17. Lever 16 has one arm 16a which engages against an end 7a of lever 7, and another arm 16b which lies under a bent spring 18. A rod 19 is slidably mounted in the lens barrel, and passes through a hole in arm 16b to engage the underside of spring 18. The arrangement is intended for use in a single lens reflex camera, and the degree to which the aperture will be shut down on triggering the shutter is determined by rotating the aperture-setting ring 2, and hence the cam ring 3. Just prior to shutter release, rod 19 is pushed upwards, causing lever 16 to push the end 7a of lever 7 so that it rotates clockwise to bring pin 8 into contact with outer edge of slot 4. The distance pin 8 moves (and hence the degree to which the diaphragm blades 9 close) are determined by the position of cam slot 4. Once pin 8 engages the outer edge of slot 4, so that further movement of lever 7 is prevented, excess motion of rod 19 is absorbed by bending the spring 18. Further rotation of rings 2 and 3 causes pin 8 to be guided into the slot 5, where it is held between the two sides of the slot, and will not be affected by lever 16, which in fact is prevented from moving by lever 7, which is not longer free to pivot. The position of pin 8 in slot 5, and hence the aperture setting, can be varied only by manual adjustment of rings 2 and 3.
