Title: System for Stacking and Grouping, or the Like
IPC: B65B35/54
Filed: 1967-11-27
Abstract: 1,193,860. Stacking and grouping articles; endless conveyers. AMERICAN MACHINE & FOUNDRY CO. 27 Nov., 1967 [26 Nov., 1966], No. 53790/67. Headings B8A and B8C. In stacking and grouping articles, particularly cigarette packs, for connecting a plurality of article feeders operating in parallel, to one parcelling machine, articles are fed from supply sources 3 on to parallel conveyers 4 and thence by conveyers 2 to stacking means 7 where they are formed from below into stacks P. The formed stacks are then pushed by a plunger 9 on to conveyer 10 which conveys the group G of stack P through the various stations S1-S4 to a parcelling machine 1. The stacks P are initially positioned spaced-apart but are closed by paddles 210 on the conveyer 10 so that there is a space at the front of each group as it approaches station S2. At station S2 a re-circulated stack R is inserted in front of the group G from the re-circulating device 17 to form a completed group G1 in station S3. To provide the re-circulated stacks R, every ' nth ' group G1 of stacks P (' n ' being the number of stacks in each completed group G1) is transferred from the conveyer 10, by a horizontal pusher device 18 at station S4, on to conveyer means 19, 22 which feed the stacks. back to station S2. Thus at every ' nth ' step of conveyer 10 no stacks are fed forward to the parcelling machine 1. This does not matter in practice since the parceller is separately driven and starts its own cycle automatically when it is fed with a sufficient number of stacks P. Also at the station S4 there is provided a movable storage unit 27. If for any reason the parcelling machine is stopped the groups G1 at station S4 are transferred into the storage unit 27 and accumulated therein so that the feed of articles from source 3 need not be interrupted. When the parcelling machine is again operative the storage unit can be reversed and the stacks P re-fed to the conveyer 10 via the re-circulating device 17. Whilst this process is occurring groups G1 are not transferred from conveyer 10 to conveyer means 19 at station S4 which means that each step of conveyer 10 feeds a full group G1 of stacks P to the parcelling machine 1. Storage unit 27 consists of two parallel endless chains 28 moved on suitable toothed wheels 29 and carrying open trays 39 each suitable for containing a group G1 of stacks P. To move groups of stacks P from conveyer 10 into storage unit 27 the group is first pushed by plunger 18 on to re-circulating conveyer 19 and then raised therefrom by elevator 42 into an overlying tray 39 of the movable storage unit. The storage unit is driven in steps in synchronism with conveyer 10 by means of a suitable reversing mechanism (Fig. 5, not shown) which enables the chains 28 to be driven at will in either direction. Should the storage unit 27 become full before the parceller starts operating again a solenoid device 6 is operated to open a trap door 5 between conveyers 4 and 2 so that articles from the sources 3 fall into a container beneath the door 5.

Abstract: 1281704 Fuel elements; moderating neutrons SNAM PROGETTI SpA 4 July 1969 [4 July 1968] 54468/71 Divided out of 1281703 Headings G6C and G6P In order to derive the thermal and epithermal neutron absorption and multiplication parameters of a cluster-type nuclear reactor fuel element, it is mounted within a cylindrical moderator column, and a thermal neutron poison is progressively introduced into the assembly during irradiation by a neutron source at the column base. The neutron poison is adjusted until the neutron flux along the column axis resumes the value attained before the insertion of the fuel. The poison may be either distributed in the moderator, 1, or inserted in the channel 11, in the space between 1 and the fuel cluster, 2, or distributed in the internal cavities within the cluster. The distribution of thermal and epithermal neutrons is determined by detectors 4, 5, 6 and 7. Correlation of the experimental results is effected in formulae derived from quadratic error considerations.

Abstract: 1,199,149. Measuring tensile properties, electrically. COURTAULDS Ltd. Dec. 8, 1967 [Dec. 8, 1966], No. 55023/66. Heading G1N. In apparatus for tensile testing a filament held between a movable and a fixed clamp provided with a load cell to measure the tension in the filament, the movable clamp is moved at a speed which is proportional to the initial separation of the clamps. As shown, the slider 1 of a potentiometer RV1 connected to a constant voltage E 1 , and the movable clamp are moved together by a motor 4, the voltage on slider 1 being proportional to the separation of the clamps. Initially, with switches S1 to S5 positioned as shown, the motor 4 positions the movable clamp to give a separation dependent on the setting of slider 9 of potentiometer RV3. Switches Si, S 3 , S 4  and S5 are then changed over, disconnecting potentiometer RV3 and connecting the slider 8 of potentiometer RV2 to an integrator 11. The output E 4  of the integrator, which varies at a rate proportional to the voltage on slider 8, in turn proportional to the separation of the clamps is compared at 6 with the voltage on slider 1 and motor 4 is energized accordingly. When the load cell (not shown) senses a pre-set loading, switch S2 is automatically opened so that the voltage on capacitor C1 provides the integrator 11 with a constant input voltage and the output of the integrator is a linearly increasing voltage.
