Title: Device for cigarette containers
IPC: B65G65/32
Filed: 1969-11-10
Abstract: 1,217,107. Hoppers. ARENCO A.B. 10 Nov., 1969 [27 Nov., 1968], No. 54860/69. Headings B8A and B8S. In a cigarette container 1 having an upper feed-in opening 33 and a lower feed-out opening 54 leading to a packaging machine (not shown), and having a storage capacity which is variable depending on alterations in the ratio between cigarettes fed in and cigarettes fed out, at least one wall part 5 of the container 1 being displaceable by means of a driving motor 23 and the feed-in opening being limited by at least one strip-shaped, flexible covering member 35 arranged to rest on the top layer 34 of cigarettes in the container, the covering member 35 is light and freely movable, and its movements dire to alterations in the upper layer of cigarettes, are sensed by means of an electric sensing member 28 which is stationary in relation to the feed-in opening, and is arranged to be influenced by alterations in an air gap 40 between the upper surface of the covering member 35 and the sensing member 28 and, when influenced, regulates the driving motor 23 so that the air gap 40 is kept substantially constant. As shown, extendable side walls 5, 5, of thin stainless steel are arranged to on the inside of fixed walls 2, 2. One wall 5 is secured to a trolley 7 which is movable by a motor 22 acting through an endless chain 17. The other wall 5 is connected to a trolley 8 which moves with the trolley 7. The top of the container is closed by a covering strip 35. One end of the latter is connected to a bracket 36 carrying a sensing member 28. The other end 37 of the strip 35 rests freely on thetop layer of cigarettes. There is a predetermined air gap 40 between a sensing member 28 and the upper surface of the strip 35. The sensing member 28 is arranged so as to transmit a signal in dependance upon the air gap thereby activating control equipment 26, which controls the motor 22. The sensing member 28 may be a capacitance (Fig. 2, not shown), the value of which is changed by the change in proximity of the strip 35. The member 28 may be a coil (Fig. 3, not shown), which coacts with a strip of metal foil (44) secured to the strip 35. In a further modification (Fig. 4, not shown) the member 28 comprises magnetic pole shoes (45, 45) which coact with a metal strip (47) carried by the strip 35. Operation.-Cigarettes are fed into the container 1 via opening 33 by opposed endless foam rubber or plastic conveyer belts 31, 32, at a greater rate than they are supplied through the outlet 54 to the packing machine. This causes the air gap to diminish. A signal is transmitted to the equipment 26 and the motor 22 is started and raises the trolleys 7, 8. The air gap 40 increases and the motor is cut out and so on. When the capacity of the container 1 reaches its maximum, a switch (not shown) is actuated to reverse the motor 22, and the supply of cigarettes is interrupted for a predetermined period of time. When the minimum capacity of the container 1 is reached, a lower switch is operated so as to reinstate the original process.

[Also in Division E2] A rod coupling, for securing a, preferably tubular rod 2 to a carrier 1, e.g. in a geodetic framework comprising carriers in the form of rings or curved anchoring rods from each of which a plurality of rods radiate, comprises a U-shaped link 3 which embraces the carrier 1 and whose arms are provided with groove formations adapted to interlock with a key formation on a body 6 or 6a which is fixed to the end of the rod 2, disassembly being prevented by a sleeve 4 or 4a which is held in position against the body or rod 2 by a wedge 7 inserted between the arms of the link 3, removal of the wedge allowing the sleeve to be slid to a position allowing dismantling of the body from the link. The wedge also acts on a shoe 11 having arcuate surfaces which match those of the carrier 1 to simultaneously clamp the assembly to the carrier, a second shoe 10 facilitating this in the embodiment of Figs. 1 and 3. In the embodiment of Fig, 5, the wedge can be rotated to the position shown instead of being withdrawn. The wedge either has an enlarged head 7c at its thin end or has an aperture 18 for a peg, to prevent complete withdrawal. A second aperture 17 may receive a peg to lock the wedge in operative position. In another embodiment (Fig. 4, not shown) the carrier 1 is of square cross-section and thus cannot normally rotate within the link 3, arcuate cut-away portions 9 formed in the link arms however allowing such rotation after the wedge has been removed to allow the carrier to be located between these portions.

Filed: 1974-12-24
Abstract: 1490238 Selective printing ING C OLIVETTI & C SpA 24 Dec 1974 [28 Dec 1973] 55804/74 Heading B6F A selector apparatus for a type-bearing element comprises a positioning member for the element, actuated by a series of cam followers and levers and controlled by selectively settable stop elements. Raw selection.-By depressing a key one of stops 268 is set starting driven shaft 85 having cams 242-245 of different profiles thereon, which cams move followers 234, mounted on levers 222-225, about crosspiece 205. The levers 222-225 move levers 226-229 to abut sliders 238-239 previously set by movement of selected stop 268. When levers 226-229 have abutted any set slider 238-239 the bail 201, 206-207 must rotate clockwise thus moving arm 80 to the left hence pushing segment 78 and ultimately causing pivoting of the type element by an amount determined by the set slider. Column selection.-Pressing a key also positions bar 353 and hence slider 349 which in turn positions either rod 339 to engage roller 332 or rod 340 (hidden behind 339) to engage roller 334 thus allowing levers 296-299 and 322-325 to move in a similar but independent manner to levers 222-225, 226-229, and giving the choice of clockwise or anti-clockwise movement of sector 62. Gears 52-53, 55, 61 are thereby turned to impart movement to the printing member which is then ready for printing. Further rotation of the shaft 85 and the action of springs brings all the levers to their rest positions. A toggle 214-216 prevents rebound. Case shift.-This is provided by rotation of plate 58 by rod 59 which is connected to a crank, biased by an overcentre spring, the crank being drive connectible by a clutch to shaft 85. The positioning of the type element, printing and reset are all performed during one revolution of the shaft 85.

Abstract: 1450930 Treating IC engine charge RANCO Inc 28 Dec 1973 [2 Jan 1973] 59982/73 Heading F1B [Also in Division G3] An exhaust gas recirculation system comprises an exhaust gas recirculation valve 14 controlling the flow of exhaust gas from the exhaust manifold 15 to the inlet manifold 13 of an I.C. engine, a fluid-pressure regulator 26 controlling the pressure applied to the valve 14 in dependence upon the rate of flow of air through venturi 12, and a secondary vacuum control valve 34 which overrides the regulator 26 to close the valve 14 whenever the throttle plate 11 of the carburetter moves to a closed or idle position. When the throttle plate 11  is fully open a low vacuum prevails at port 63 downstream of the venturi 12 which, when applied to a chamber 52 of the control valve 34 causes valve-member 56 to shut off the vacuum derived from the inlet manifold 13 and admit atmospheric air from vent 60 to the port 55 and thence chamber 20 of the valve 14 so that the valve-member 24 closes. When the throttle plate 11 is positioned in its mid range, the port 63, being downstream of the plate communicates an increased vacuum to the chamber 52 which in turn opens the valve 14. When the throttle plate 11 moves to its idle or closed position the port 63 becomes located upstream of the plate and once again a low vacuum prevails which, when applied to chamber 52 causes the valve 14 to close. A check valve or reservoir may be placed in conduit 27 so that a sudden drop in vacuum in the manifold 13 will not necessarily cause a loss in vacuum in chamber 20.
