Title: Cutting rock in tunnels - plasma jetted onto rock forms arc current path along layer to electrode
Inventor: THORPE MERLE LEE
IPC: E21C37/16
Filed: 1973-10-31
Abstract: Cutting rock or concrete in tunnels etc. is effected by directing a main plasma jet burner onto the rock face so that a layer of rock is melted which, together with the jet, is contacted with a second electrode which thus draws the plasma jet out over the layer of molten rock. Voltage is now applied between the electrode and the jet so as to strike an arc through the plasma so that current now flows from burner to electrode by way of the jet. The effect is to heat up the rock below the molten layer in addition to this layer and so form an incision in the rock face. The second or counter electrode should be formed by a jet of plasma directed onto the molten layer, or again should be made of graphite.

Title: Acupuncture point detector - photodiode in test prod., coupled to operational amplifier circuit
Inventor: KAUCKY HEINZ DIPL ING
IPC: A61H39/02
Filed: 1974-06-28
Abstract: A pocket size tester finds acupuncture points on the skin by measuring the direct current resistance, with the point indicated on exceeding a given threshold resistance, between a test prod placed against the measurement point and a large surface counter-electrode. The indicator is a photodiode in the test prod, i.e. in the direct fielf of vision of the practitioner. Preferably, when a input voltage is supplied to the operational amplifier by the voltage divider formed by the resistance of the patient and the variable resistor, the transistor conducts the current flows through the GaAs photodiode as defined by a fixed resistance. The amplifier is feedback-coupled for min. gain, to give a slow response of the diode on approaching the acupuncture point.

Title: Rail-bound track aligning, levelling and consolidating machine - comprising direction-beam-connected plant wagon and consolidating wagon
Inventor: BREYER WALTER
IPC: E01B27/17
Filed: 1974-07-16
Abstract: The permanent-way working machine, which moves along the rails, is for aligning, lengthways and crossways levelling and consolidating railway track. An aggregate plant wagon (1) and a consolidating wagon (2), interconnected by an alignment carrier (3). One end of the latter transmits aligning forces from the alignment cylinders (4, 4a), to the track, and hoist forces from the hoist cylinders (5) in lengthways levelling, in the area of the consolidating devices (6); the other end provides support for the reactive forces of the alignment forces and hoist forces across the plant wagon's wheel sets (21), only onto the track which has not yet been worked. The force required for crossways levelling is introduced by the superelevation hoist cylinders (8, 8a), and transmitted to the right or left rail via the frame of the consolidating wagon and correspondingly shaped transmission devices. No laterally directed reactive forces can reach the newly worked track.
