Abstract: 1,233,824. Packaging machines. A.M.F. Inc. 29 May, 1969 [11 June, 1968], No. 27191/69. Heading B8C. In a packing machine for checking the exact number and density of cigarettes to be packaged an endless conveyer 1 carries a number of boxes 8 which are packed with cigarettes having their ends accessible through open sides of the boxes and has vertically mounted, on opposite sides, a pair of sensing drums 401 which are rotatable in opposite directions tangential to the box sides at the same speed as the conveyer and which carry four sets of spring-loaded, radially slidable, pins 403 which, in each set, are spaced similarly to the cigarettes in the boxes. The pins 403 are able to penetrate a certain depth into the open sides of the boxes in radial alignment with the cigarettes therein. During operation the pins 403 of each drum meet the corresponding cigarette ends which, if present and of the desired density, force the pins 403 back against their springs 405 to be held in their retracted positions by spring tongues 408 which engage behind pin heads 407. If all of the cigarettes in a box are regular in number and density all of the pins 403 will be pushed and held back and none will touch a movable striker plate 413 so that a microswitch 415 will not be actuated. After a set of pins 403 has passed the striker plate 413 a vertically reciprocable slide 409, which carries the series of spring tongues, is moved upward by a circular cam and wheel mechanism 410, 411 to disengage all of the spring tongues from the pin heads 407 so that the pins 403 project outwardly again ready for another sensing operation. If only one cigarette is missing, or has a density below a pre-set minimum, the associated pin 403 continues to protrude so as to hit the striker 413 and actuate the switch 415. The latter acts upon a locking device 416 and prevents the forward movement of a pusher 16 which is adapted to transfer the stacks of cigarettes from the respective boxes into aligned packages.

An apparatus for testing the bonding of a wire 36 connected to an electric circuit and for testing the slackness of the wire comprises a hook 10 suspended from one end of a pivoted beam 6 which is loaded at its other end. A load is applied to the wire by depressing lever 17 to lower the hook, engaging the hook under the wire and releasing lever 17 which is then pushed upwardly by spring 19 to abut stop 21. If the wire is satisfactory, the movement of the beam is arrested before lever 17 abuts stop 21 and a signal lamp 32 is lit as a result of the cam 29 ceasing to contact the beam. If the wire breaks loose or is too slack, the beam remains in contact with cam 29 and no signals given. A damper 18 is connected to lever 17. Lever 17 moves between adjustable stops 20 and 21 and both stops may be lowered or raised in unison by screw 23 to compensate for differing thicknesses of tested circuit boards. In the hook of Fig. 1 and 2 the hook is maintained vertical by co-operating shapes of the support 5 and the hole 4 receiving the support. The part 3 acts to damp oscillations of the hook tip. In the hook of Fig. 3  the co-operation of magnet 35 with ball 3 serves to maintain the hook vertical and to damp oscillations of the tip.

[Also in Division F1] An annular flame tube for a gas turbine engine having primary and secondary combustion air inlet passages has variable air flow restricting means associated with at least one of the passages, the restricting means being expandable in response to an increase in a variable control quantity to vary the ratio of primary to secondary combustion air. In one arrangement, Fig. 1, the annular flame tube 30 is enclosed by outer and inner annular walls 31, 32. The space between tube 30 and wall 31 contains a series of louvre type restrictors 90 controlling ducts 91 terminating in nozzles 92 which direct secondary air into the burning mixture of fuel and primary air, the latter air having entered the flame tube past fuel nozzles 33. Each set of louvres 90 is pivotal by means of a Bourdon tube 93 which receives a variable control pressure from a common manifold 94. Dilution air flow through nozzles 95 is controlled by closure members 96 having pressure operable bellows 97. In a modification (Fig. 5, not shown), Bourdon tubes (180) control the pivotal movement of restrictor segments (185) mounted in the primary air inlet passage. In a further modification, Fig. 3, the flame tube has a series of angularly spaced primary air inlet passages 140, each having a flow restrictor formed by angled end pieces 141b on bimetallic strips 141a. The latter are mounted on a ring 142, electric heating of which causes strips 141a to deflect so that end pieces 141b project further into the flow. Swirl vanes 143 are provided and surround a burner (not shown). In a similar arrangement (Fig. 4, not shown), the movement of restricting shutters (150 to 153) into the primary flow is controlled by electrically heated bimetallic strips (159, 160, 162, 163). In a further modification (Fig. 6, not shown), the primary flow is controlled by a spiral restrictor (200) extension and retraction of which is controlled by a pressurizable bellows (201) slidably mounted by means of sealing rings (203) on a central spindle (202).
