Abstract: 1,185,059. Delay lines. SOLARTRON ELECTRONIC GROUP Ltd. 8 Nov., 1968 [22 Nov., 1967], No. 53239/67. Heading H1W. A four-terminal delay line comprises two conductors, one of which is provided with inductive loops and has inductance L and resistance R per unit length, the ratio L/R being equal to C/G, where C and G are respectively the shunt capacitance and shunt conductance per unit length of the line. The line is loaded either by a resistive material or by discrete shunt resistors in order to decrease G and enable R to be increased. It is thus possible to reduce the gauge of the line conductors and hence its overall size whilst preserving the desirable frequency characteristic expressed by the criterion L/R = C/G. As shown, the line consists of serpentine conductors 10, 11 printed on opposite sides of a sheet 12 of PTFE. The line is loaded by shunt resistors 19 which are connected between conductive areas 17, 18 extending respectively from the conductors 10, 11. In a modification (Fig. 5, not shown), the resistors are in the form of areas of resistive film printed on both sides of the sheet 12 and joined by conductive material deposited on the edge of the sheet.

Filed: 1969-11-18
Abstract: 1279830 Packaging SCHWEIZERISCHE INDUSTRIE-GES 18 Nov 1969 [19 Nov 1968] 56254/69 Heading B8C Tea-bags in the form of a continuous band made from paper webs sealed and scored at 2a and providing transverse and longitudinal rows of interconnected bags are individually separated and are arranged in individual stacks in a cardboard carton 11. A conveyer 1 deposits the first and second transverse rows of interconnected bags on a spring-loaded plate 4 and table 3, respectively, the leading edge of the band interrupting a photo-cell and light arrangement to stop the conveyer drive. A cam drive (not shown) lowers a pressure member 6, which is carried on rods 7 and has a plurality of fingers 6a, against the first bag row and forces the bags on to projecting edges 9 on the plate to separate the bags from one another and the second bag row on the table 3 along weakened regions 2a. Four suction heads 12, which are carried on a pair of levers 14 pivoted on pins 17, pick up the separated bags and carry them above the carton 11, which is positioned on intermittently-moved conveyers 10. Vertically-reciprocating pushers 25 disengage the bags from the suction heads and accelerate downwardly faster than gravity to direct the bags into the box. The levers 14 are oscillated about pins 17 by a pair of rods 18 and 19 coupled to a central lever 14a rigidly connected to levers 14. The suction heads are reciprocated over alternate short and long strokes by a cam and lever linkage arrangement which operates to oscillate the levers 14 through alternate small and larger angulars thereby permitting two bag stacks to be formed in the carton. The cam and lever linkage arrangement comprises rods 18 and 19 each connected between the central lever 14a and a respective one of a pair of links 20, 21, which are guided by half elliptical grooves 30, 31 in respective cam segments 32, 33. In a first 180 degrees of cam rotation, the pivotal movement of link 20 is constrained by its associated cam segment groove 30 and moves rod 19 to reciprocate the suction heads over a long stroke. During this period, the link 21 is not in engagement with its associated cam segment groove 31 and hence link 21 and the rod 18 merely follows the movement of the lever 14a imposed by cam segment 32, link 20 and rod 19, Fig. 6 (not shown). Conversely, in the next 180 degrees of cam rotation, link 21 is entrained in the groove 31 of cam segment 33 to reciprocate the suction heads over a short stroke by way of rod 18, Figs. 4 and 5 (not shown). During this period, link 20 is disengaged from its associated groove 30 and, together with rod 19, merely follows the movement of the lever 14a imposed by cam segment 33, link 21 and rod 18. By adjustment of the rod connections in the lever and link slots 36, 37, the relative lengths of the alternate suction head strokes may be changed to vary the overlap of the bag stacks, Fig. 2 (not shown). The cam segments 32, 33 may be replaced by a single cam disc.
