Abstract: 1330558 Testing metal for solderability MARCONI CO Ltd 7 Aug 1972 [11 Dec 1971] 57656/71 Heading G1S An adjustable probe 20, Fig.1, is inserted thro' a small hole in a cross member 6 so that its end 22 is at a level with the surface of molten solder 2 in an electrically heated pot 1, the end then being sighted thro' a microscope 15 and the height of the solder surface read from a micrometer 19. A strip of metal to be tested for solderability is then fluxed and held in a clip 7 and slowly dipped into the pot 1 by allowing the rod 8 and member 9 to slide down from the position shown in Fig.1 thro' a hole 10 in the member 6, the rate of movement being governed by the friction of a pin 14 fixed to 6 sliding thro' a hole 13 in the member 9. In Fig.4 the fixed pin 14 moves relatively into a blind hole 13 and acts as a damper to movement of the rod 8. When the head of member 9 abuts the member 6, the height of the solder meniscus on the sample in the clip 7 is read and the solderability of the metal sample determined from an equation quoted in the Specification. In the prior art referred to, samples have been fluxed and solder dipped and the time taken to become solder wetted has been taken as an indication of solderability.

Title: Electronic flash lighting equipment
IPC: H05B41/32
Filed: 1972-02-09
Abstract: 1334120 Supply circuits for flash tubes BOWENS SALES & SERVICES Ltd 9 Feb 1972 [2 March 1971] 5765/71 Heading H2H An electronic flash unit comprises a flash tube E provided with a power supply and triggering arrangement and a modelling light LH, the triggering of the flash tube causing, at least for a time thereafter, the light output of the modelling light to be modified. The tube E, which is fired by a circuit F, and the tungsten filament light LH have their light outputs controlled by respective switches S3A, S3B and a triac Q. When storage capacitors C1, C2 are discharged to fire the tube, a relay RY1 is energized for a time thereafter determined by a capacitor C3 and a resistor R1 thereby opening contacts RY1A and preventing a supply of charging current. A second relay RY2 is energized before the capacitors C1, C2 are fully charged to extinguish a neon lamp N2. When the capacitors C1, C2 are fully charged, a thyristor D3 is triggered via a discharge device V so that a third relay RY3 is energized thus closing contacts RY3C to illuminate a "ready" neon lamp N1, closing contacts RY3A to illuminate the light LH and closing contacts RY3B to enable the flash tube to be fired. On firing the flash tube, the decrease in voltage across the capacitors C1, C2 switches off the thyristor D3 thereby de-energizing the relay RY3 and switching off the light LH until the capacitors have re-charged. A dimming resistor may be connected across the contacts RY3A to dim instead of extinguish the light LH or the light may be made to flash during the capacitor recharge period.

Inventor: SZOPINSKI JAN ZBIGNIEW
IPC: A61B/
Filed: 1999-07-06
Abstract: The invention provides an apparatus and method for automatic evaluation of skin resistance or impedance variations in order to diagnose the state of health of at least a portion of a human or animal body. The difference between an AC impedance measured at a specific frequency and at a specific skin area with a calibration electrode and a reference electrode and the impedance measured at a similar frequency and in the same area with a measurement electrode and a reference electrode, is used to determine the state of health of the internal organ corresponding to the examined skin area. Alternatively, the skin between the electrodes is exposed to a DC potential of a magnitude selected to give a break-through effect. The resistance of the skin is measured between a measurement electrode polarised negatively with respect to a reference electrode, and the DC resistance of the same skin area is again measured but with the measurement electrode polarised positively with respect to the reference electrode. The ratio of these two values is used to determine the state of health of the internal organ corresponding with the examined skin area.
