To lift a load on a cable 29 running in the groove of the drum 18, the handle 28 is oscillated whereupon a sleeve 102 is screwed along a thread 10 on a shaft 26 mounting the pinion, 24, to cause frictional locking between the sleeve 102, friction linings 114, 116, disc 108 and a flange 106 on the shaft 26. Further oscillation of the handle causes intermittent rotation of the pinion 24 and drum 18 to raise the load. Teeth 110 on the outer periphery of the disc 108 engage a pinion 118 which is mounted through a one way device 120 so that it free-wheels during raising of a load but locks in the other direction. To lower the load, the handle 28 and one way device 32 are reversed on the sleeve 102 and oscillation of the handle causes release of the frictional lock between the sleeve discs and flange 106, the lowering.load however causes the frictional lock to be operative again until further release by the handle 28. A compression device (82), Fig. 1 (not shown), for urging the cable into the winding drum groove comprises a cable engaging roller urged against the cable either by a spring, or through a system dependent on the tension in the loaded cable.

Abstract: 1300600 Superconductive circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 2 Dec 1970 [5 Dec 1969] 57238/70 Heading H3B In order to decrease the amount of thermal leakage in a superconductive circuit in which superconductive coils forming the focusing coils of an electron beam apparatus e.g. 33, 36, 39 are individually energizable the coils are connected in series between supply conductors 42, 45. Each coil is associated with a superconductive switch 34, 37, 40 whereby persistent currents may be established in circuits 30, 31, 32. A persistent current in e.g. coil 36 is established by driving switch 37 resistive via current through control winding 38 and applying a current to terminal 42 which flows through coils 36. Switch 37 is again rendered superconductive and the applied current slowly reduced to zero thus providing a persistent current in 31. Since switches 34, 40 remain superconductive then due to the impedance of coils 33, 39 the applied current does not affect the persistent currents in coils 33, 39 so that the coils may be individually energizable. To vary the current intensity in one of the circuits 30, 31 or 32 a current is applied to terminal 42 of equal magnitude but opposite sign to the current flowing through the superconductive switch of the required circuit so that the effective current through the switch is zero and the latter can be opened without affecting the coil currents. An increase or decrease in the applied current results in a current variation through the coil concerned after which the new current is again made persistent by closing the switch.

The charging apparatus is mounted on a larry car and is moved so that it is placed in position for feeding two non-adjacent ovens 45, 55. When in position, the oven lids are removed and each oven of the pair is charged in turn by turning the screw 21 first in one direction and later in the opposite direction. For gases produced in the ovens, each oven has an ascension pipe leading to a collector main. When charging an oven, not all the displaced air and gases evolved from the oven can escape through the ascension pipe of the oven being charged. However, the tubular member 19 provides an interconnection between the oven being charged and another oven whereby the excess gases can escape to the other oven and thence through that oven's ascension pipe. Pipes 41, 43 supply purging steam or inert gas. At the bottom of the coal hopper 37, there may be a sliding gate or butterfly valve. Each oven may have four charging holes in which case the charging apparatus comprises four hoppers. The lid lifting apparatus may be as described in Specification 1,349,819. Magnetic lid lifters and batteries where lids are removable manually may be used.

In Fig. 1, actuation of a key 10 activates a gate, corresponding with that key, and, if so selected by octave control 12, any number of higher notes having integral numbers of octave separations from the note activated. Simultaneously, the sequential read-out 13, is activated by a control pulse via lead SS. Readout 13 scans out all activated gates in sequence, to a limit of twenty gates, in such a way that the selected gates pass tones in terms of note nomenclature, up, in order of increasing frequencies and down, in order of decreasing frequencies. The gates lead to tone colour filters 14, amplifier 15 and loud-speaker 16. Read-out 13 may be disabled by a switch 18, the "piano mode" whereby any chord played is sounded as a chord; or, on closure of switch 17, the "up only mode", the gates are scanned upwards, and then rapidly reset and re-started if any key is actuated; or, on closure of switch 19, the "up and down mode", the chord selected is scanned up and then down again at the same speed. The gates employed may be variable sustain gates, and the time required to complete an arpeggio is variable at will. For reasons of economy in circuitry, the tone gates are, for the purposes of scanning, grouped in units of three, so that only one out of three adjacent notes may be sounded at the one time.
