Abstract: 1293794 Measuring impedance and current density; electro-medical apparatus F HOFFMANN-LA ROCHE & CO AG 21 Oct 1969 [21 Oct 1968] 29998/69 Headings G1U G1N [Also in Division H3] The impedance of or current density in a current conducting medium, 10, e.g. brain tissue or a solution, is measured by inserting into the medium a probe 11 whose head 13 carries spaced current electrodes 16, and adjusting the current I allowed to flow from the medium into one electrode and then from the other electrode back into the medium until it equals the current that would have flowed through the volume of the medium displaced by the head. In this condition the probe head introduces no disturbance into the medium, and from the magnitude of the current I and the known dimensions of the head the current density in the medium may be calculated. The impedance of the medium may also be determined since minute sensing electrodes 15 are provided to detect the voltage difference E between the current electrodes. The no-disturbance condition is arrived at by measuring the voltage difference Eoc when the current I = 0 and then increasing I until the voltage difference has been reduced to a predetermined fraction k of Eoc, k being a constant for all media, determined by calibrating the probe in a medium of known impedance. The cylindrical or cubical probe head 13 is of epoxy material and the current electrodes 16 of silver chloride are disposed at its two ends 14. The sensing electrodes 15 are positioned in the centres of the current electrodes, and the voltage difference between them is, after amplification (21), both indicated (21<SP>1</SP>) and used to adjustably control (22<SP>1</SP>) the current I.

Abstract: 1451794 Cinematograph film transport WESTREX CO Ltd 19 June 1974 [25 June 1973] 30014/73 Heading G2E Film is transported through a projector by a first motor 2, and taken up on a spool driven by a second motor 13, motor 13 being energized before motor 2. As shown, the film 4 passes from a supply spool 5 into the projector, where it is guided round a sprocket 3 and fixed roller 15 to pass over a movable roller 16 and so out of the projector to the take-up spool 6. Roller 16 is carried at one end of an arm 17 pivoted at its other end 18, the arm being spring-biased upwards. Its movement is controlled by a dashpot 20, which permits free upward movement of arm 17, to increase the film loop length, but offers resistance to its downward movement. The take-up spool 6 is driven by a torque motor 13. Both motors are supplied from an A.C. supply 21, 22, by means of a "start" contact 23. This closes contact 24À1, and motor 13 is supplied by way of a resistor 28 whose resistance falls as its temperature increases, so that the motor torque increases. Film from the loop over roller 16 is now taken up to tension the film. The "start" contact also operates a delay relay to close contacts 25À1 and 25À2. Closure of contact 25À1 short circuits resistor 28 so that motor 13 is increased to full torque power. Closure of contact 25À2 energizes relay 26 to close the supply circuit for the projector drive motor 2, a few seconds later. This can now be energized at full power without risk of film breakage.
