Title: Improvements in or relating to endless belt conveyors
IPC: B65G17/02
Filed: 1945-09-18
Abstract: 601,625. Rope-driven conveyers. SUTCLIFFE, R. J., SUTCLIFFE, T. D., SHEPPARD, J., and SUTCLIFFE, W. F. Sept: 18, 1945, No. 24074. [Class 78 (i)] A tensionless belt 1, Fig. 1, which may be troughed by idler rollers 5 is driven by endless rope 2 which engages clips 3 secured at intervals to the belt. The clips 3 may have a frictional lining. Alternatively, the clips may be secured to another rope (not shown) which itself may be secured to the belt. The rope 2 runs over pulleys 10 along its length, to the supports 16 of which bars 15 may be fixed so that the clips and therefore the belt may be aligned. Two or more ropes may be used. The rope may be driven by being wrapped round a driving pulley (not shown) several times and is returned either round pulley 11 or round a separate centre pulley (not shown) on belt drum 6. To accommodate the clips, belt end drums 6 and idler rollers 10 may be divided or split. The rope may engage the clips on both upper and lower stretches. Guiding means 12 may guide the driving rope accurately between the clips.

Title: Method of and apparatus for the elongation or extinguishing of electric arcs
IPC: H01H9/44
Filed: 1954-08-19
Abstract: 762,642. Arc-rupturing in switches. CALOR-EMAG ELEKTRIZITATS-AKT.- GES. Aug. 19, 1954 [Sept. 1, 1953; Oct. 13, 1953; Oct. 14, 1953; Feb. 24, 1954], No. 24179/54. Class 38(5) [Also in Group XI] An arc-quenching device is arranged so that the point of initiation of the arc on separation of contacts is within a powerful magnetic field which will extend the arc and so that at least one arc foot is moved by a magnetic field along a conductive bar locaced in a slot in a ferro-magnetic jacket, the slot providing an air gap in the path of the magnetic lines of force which is substantially deeper than the mean length of path of the lines of force across the gap. Fixed arcing contacts (Fig. 1) forming part of conducting bars 4, 6 lie within magnetic jackets 7, 8 of U-shaped cross-section. The arc feet are moved rapidly upwardly along bars 4, 6 and on to bars 11, 12. The jackets 7, 8 may carry exciting windings 9, 10 and additional exciting windings may be connected on passage of the arc from one bar to the next. Additional lengthening of the arc may be obtained by the provision of auxiliary pole pieces 28 (Fig. 5) so that after the arc 27 has been produced on bar 24 it assumes the position 29 at the edge of the energizing magnet 26. The arc wander bar may be of meandering form (Fig. 10, not shown) to accommodate lengthy arcs in a small space, and the length may be further increased by the provision of numerous additional pole pieces on the energizing magnet. Insulating partitions carrying transverse iron members may be positioned between the wander bars to effect elongation of the arc when it penetrates the labyrinth thus formed. Curved wander bars 48 (Fig. 12) may be employed and they may be further extended to the form of a plurality of windings on a drum, walls of insulating material being arranged between the turns to prevent short-circuiting.

The H.F. power to be measured is applied to thermistor T, Fig. 1, in bridge RA-T and a shunt resistor R2 is then switched in at Sand varied until the bridge is restored to balance and under this condition T has the original resistance and the meter M in the shunt circuit reads H.F. power. Under different ambient temperature conditions the bias current I0 will vary but the sensitivity of M is automatically adjusted as the bias resistor R1 is varied to produce bridge balance and I0. In another arrangement shown in Fig. 2 the bias resistor RC is ganged to a second variable resistor RV in the R2 shunt circuit and a fixed resistor RF shunts M/RV and the bias circuit includes fixed resistors RD, RB. The Specification includes mathematical explanation with reference to Figs. 1 and 2.
