Abstract: 1,165,162. Conveyers. MFRS. EQUIPMENT CO. Ltd. 14 Nov., 1966 [12 Nov., 1965], No. 48027/65. Heading B8A. Articles on the belt 10 of a main conveyer may be diverted on to a branch roller conveyer 18 by lowering a portion of the main conveyer run. This portion is supported on wheels 20 which are movable vertically under the control of a linkage (22) and a double-acting cylinder (24) (Fig. 2, not shown). Lowering the belt and wheels 20 causes conveyed articles to be lowered on to transfer wheels 30 arranged so as to cause a moving article to be turned on to the branch roller conveyer 18. Alternatively, this conveyer may be of the belt type and a transfer plate be interposed between the main and branch runs. The rollers 30 define an inclined plane in either or both of two directions, i.e. along the length of the main conveyer and across its width. Operation of sensing means, e.g. a feeler, which controls the cylinder 24, may depend upon the height or width of the articles. By using some form of marking or signal on the articles and by the use of electronic or light-sensitive devices for sensing, articles may be sorted and diverted to various branch runs.

Title: Flip-flop stages
IPC: H03K3/037
Filed: 1972-10-27
Abstract: 1345858 Bistable logic circuits VDO ADOLF SCHINDLING GmbH 27 Oct 1972 [9 Nov 1971] 49677/72 Heading H3P [Also in Division G4] The effects of interference voltages on a bistable 1 comprising four logic gates 5, 6, 7, 8, are reduced by introducing time constants 9, 10 into the cross-coupling of gates 5, 6, and relatively larger time constants 13, 14 into further feedback circuits from the outputs of gates 5, 6, to respective inputs of gates 8, 7. Four such bistables 1, 2, 3, 4, constitute a counter, and a further discrimination against noise is provided by a pulse shaper 12. This includes 1.p. filters 20, 21 and Schmitt triggers 18, 19 which drive a NAND gate 22. The gates used in the bistables are NAND gates. The time constants 13, 14 are preferably ten times those 9, 10.  In operation, a 1 from an inverter 11 when NAND 22 output goes to 0 in response to an input 21, makes the inputs to NAND 7 all 1, the other two inputs being at 1 because of 1 from a NAND 16 and a 1 from NAND 6 output via RC 14. One input of NAND 5 therefore goes to 0 and its output to 1, changing the state of cross-coupled gates 5, 6. The 1 fed back to NAND 8 input is slowed by RC 13 so that the input 1 from 11 has ceased before the fed-back 1 becomes effective. The second pulse 1 from 11 then makes both inputs to NAND 8 because 1 and its output 0 changes NAND 6 output to 1 to reset the crosscoupled pair 5, 6. In this case RC 14 slows the feed-back of 1 to NAND 7 input. The second 1 from 11 also causes both inputs to a NAND 15 to be 1, and an output 1 goes to the second stage 2. The NAND 16, which supplies the third input to all the NAND gates 7, receives as inputs: the output of the NAND 5 of the stages 1 and 4, the input pulse from 11, and a 1 or 0 from switch 17. If switch 17 supplies a 1, decimal counting is effected, and if a 0, binary counting.

Abstract: 1319153 Magnetic storage devices FUJI DENKI KAGAKU KK 21 Oct 1970 [27 Oct 1969] 49938/70 Heading H3B A magnetic storage device comprises a laminated ferrite body having two orthogonal sets of parallel tunnels containing removable drive conductors, the tunnels each having a flat face of width l and having a height h such that h #0À5l. Fig. 2b shows two orthogonal tunnels 5, 6 whose cross-sections are a segment of a circle. The requirement that h # 0À5l produces an optimum ratio of the length of the flux path around the crossing point of the tunnels, L 1 , to the distance around one tunnel, L 2 . This optimum ratio of L 2  : L 1 , which is about 0À68, reduces back voltages, speeds switching, and reduces output waveform distortion. The device may be made by pressing wires into two green ferrite sheets and laminating the sheets together. Suitable tunnel cross-sections are rectangular, triangular, segmental and trapezoidal; flux path lengths for these sections are given, Fig. 5 (not shown).
