Abstract: 1,233,349. Washing bottles &c. SYBRON CORP. 19 July, 1968 [28 July, 1967], No. 46724/70. Divided out of 1,227,388. Heading B8T. [Also in Division A4] A transfer valve incorporated in a spray action washing machine, e.g. for bottles, crockery &c. is responsive to the distance between the valve and an article-carrying dolly received in said machine for supplying washing fluid to the conduit system of a dolly of the through-flow type or for providing a spray when a dolly not having conduits is received. The valve has a cylindrical valve body 12 connected to a water inlet 10, the body having ports 22. A valve member 34 is slidingly located inside the body by a plurality of 0-rings 36. The valve body is enclosed by a rotatable cylinder 28 having perforated sprinkler arms 30. When a throughflow dolly having a bottom member 46 is received over the valve member 38, water pressure pushes the valve member upwardly until it seals against the conduit system inlet 52 to supply water to the conduits, the ports 22 remaining sealed as shown in Fig. 1. A dolly with no such conduit bottom member 46 allows the valve member to rise to its full extent, flange 40 sealing against the head 42 of a rod 18 to cut off its water supply. This movement opens the ports 22 allowing water to flow to the sprinkler arms 30 which rotate due to the position of the perforations 32. The dolly bottom member 46 may be constructed at such a level as to allow supply of water both to the conduits and to the sprinkler arms.

Abstract: 1,238,824. Grain cleaners. CLAAS GEB. 26 May, 1970 [29 May, 1969], No. 25186/70. Heading A1F. The cleaner for a combine harvester operates by drawing air in from outside the harvester through an intake opening 12, located below the screens 8, 10, which occupies the entire width of the screen casing 9. The casing 9 form with cleaner casing 7 an enclosed channel along which the air passes through the oscillating screens 8, 10 and the separated chaff is sucked out through suction air blowers 11 preferably axially constructed. The blowers or fans 11 are located at the rear of the combine, are effective over the whole width of the screens, and the chaff is expelled into the atmosphere via ducts 22 (Fig. 4). More suction channels may be connected to the casing 9 each having a control flap to shut off the channel if required and these channels are used to extract dust and the like from other parts of the harvester. In operation the grain/chaff mixture passes through the concave 4 on to oscillated grain pan 5, which conveys the mix to the first or only screen 8. Any grain from the straw walkers 6 falls directly on to grain pan 5 or slides thereto down cleaner casing 7. Cleaned grain falls into one of the augers below the screens and the tailings and heavy ears into the other auger to be returned to the threshing mechanism. An arrangement of the blowers 11, is shown as viewed from the rear (Fig. 4) with the ducts 22 outside the harvester. In other embodiments the ducts 22 and blowers 11 are closer together and inside the harvester, or a single duct is positioned between the blowers which extract from the outerside inwards.

Abstract: 1,251,402. Electronic counters. KIENZLE APPARATE G.m.b.H. 7 Feb., 1969 [14 Feb., 1968], No. 6738/69. Heading G4A. Each stage of a static ring counter comprises three NOR gates or three NAND gates. The logic conditions are shown for the inoperative condition using NOR gates, with all flip-flops A, B in O, L condition, i.e. off. In these circumstances all the preparation gates C remain at O because of the L input from the like-numbered B gate. The counter is rendered operative by an L pulse on one of leads 23, say to B1, when B1 goes to O and sets A1 to L. The next Z pulse, equal to O, changes C1 to L for the duration of the Z pulse, stage 2 turning on and stage 1 off, and remaining so after the pulse ends. All stages may be returned to zero by a pulse on lead 21. The circuit may be simplified (Fig. 2, not shown) by omitting the individual marking lines 23 and connecting the zero line 21 to set the first stage to L and the rest to zero. Reversible counter, Fig. 4. Forward and reverse pulses are applied to leads 22, 32, respectively. The preparation element comprises two NOR gates Ca, Cb, the output of Ca always being the complement of the related gate A. Cb feeds the related gate A and the gate B of the next stage. Forward pulses therefore act on Cb to effect direct switching. Reverse pulses act through a further NOR gate D to feed the related Ca, Cb preparatory gates and gate B of the preceding stage to effect reverse stepping. The polarities are inverted (Figs. 5-8, not shown) when NAND gates are used.

The web may be the cigarette wrapper web or the uniting strip web. Joins in the web are detected photoelectrically upstream of the assembler unit and each resultant signal is applied, after a delay if necessary, to momentarily stop the mouthpiece feed mechanism to withhold at least one (preferably at least two) mouthpieces from being fed to the assembler unit. The cigarette(s) emerging from the assembler unit corresponding to the web join thus lack a mouthpiece and is (are) ejected by known means for ejecting incomplete assemblies. The system may be used for single or double length cigarettes. The momentary stopping of the mouthpiece feed mechanism is effected by fluid pressure actuation of a clutch to disconnect the drive thereto.
