Abstract: 1,154,402. Sheet cutting, delivering and stacking apparatus. HANS BIEL K.G. 13 June, 1966 [13 Nov., 1965], No. 26203/66. Heading B8R. In a sheet cutting, delivering and stacking of apparatus sheets 3 are cut from a paper web 1 into predetermined lengths by a rotary transverse cutter 2 and delivered by a train of rollers 4 to the nip between a roller 8 and a suction roller 5 over an arcuate guide 7, the suction roller 5 rotating at a peripheral speed which corresponds to the linear speed of the sheets so as to engage the leading edges of the sheets 3 with one of a number of peripherally spaced, axially extending rows of suction apertures 6 which are selectively actuated by control means (not shown). The position of the roller 8 and its associated endless belt 9 is displaced relative to the train of rollers 4 in accordance with the predetermined length of the sheets to be cut. The suction roller 5 delivers the cut sheets to a roller 18 by means of a pivotal stripper 15 which transfers the sheets, whilst the suction is interrupted concomitantly, to the roller 18 moving at a slower peripheral speed than the suction roller so as to cause the sheets to overlap one another. The sheets are then delivered by cooperating sets of rollers 21, 25... 28, 24 to a pair of superposed endless belt conveyers 31, 32 (Fig. 2), which stack the sheets on a table 41 against a pivotal gauge 42, 44. The end roller 32 of the lower belt conveyer is adjustable with respect to the gauge in accordance with the length of stacked sheets S. The end roller is also associated with air blast pipes which induce separation of the sheets from the conveyer belts. The sheets which are delivered by the conveyer belts are stacked in counted batches by the interposition of a pivotal separator 43. The counted batches are removed by a reciprocating gripper 46 following upward pivotal displacement of the gauge 42, 44.

Abstract: 387,037. Automatic circuit-breakers. BARNETT, A., 3, Hillfield Avenue, Hendon, London. Sept. 26, 1931, No. 26910. [Class 38 (v).] An automatic cut-out which is adapted to open a circuit such as a battery circuit when any temporary diminution of current occurs therein due, for example, to a loose connection, has a single winding 2 in series with the battery, this winding normally holding a hand-set armature 13 in the attracted position in which a bridging member 14 dips into mercury cups 18. Adjustment for release at a predetermined minimum current is effected by an adjustable core member 9 the polepiece of which is arranged to be separated from the armature by a suitable air gap so that when the current falls below the predetermined value the spring 21 overcomes the magnetic attraction of the armature and breaks the circuit at the mercury cups 18. The method of adjustment of the core 9 is shown in Fig. 3, the core being urged upwardly within a sleeve 4 by a spring 11, the threaded lower end of a depending portion 10 of the core carrying an adjustment nut 12. The core is prevented from rotating during adjustment by a screw 141 engaging a recess 15 in the core. The armature is reset after release by a spring- returned manually-operated plunger 25 bearing on the upper side of the armature 13. This plunger acts as a contact when the armature is released and engages it, so closing an alarm circuit including a bell 28.
