Abstract: A liquid level gauge consists of two main cells comprising a measuring electrode, a compensation electrode and their respective counter electrodes. Circuitry is provided to determine the conductance of the liquid in each cell. Further circuitry is provided to calculate the quotient of the respective cell conductances, which is indicative of the liquid level. The surface areas of the measuring and compensating electrodes are kept equal, but the distance between the measuring electrode and its counter electrode increases linearly, while the distance between the compensation electrode and its counter electrode is constant.

Abstract: A tool has outer gripping jaws 12, 19 to grip a cable 20, and inner jaws with cutting edges 30 which penetrate the cable.The inner jaws are initially located for sheath penetration and are then displaced axially to strip the cut portion of the sheath of the core of the cable. In the axial movement the inner jaws are guided along tracks on the adjacent faces of the outer jaws and at least one of these tracks 100 is relieved at 102 so that during the axial movement the cutting jaws separate. This enables the tool to operate satisfactory even when the jaws converge towards the axis on which they are pivoted.

Abstract: Envelopes are fed in a mutually overlapping state one by one toward a stopper provided at the front side of a transfer conveyor. Upon abutment with the stopper the envelopes pile up so as to be temporarily stored. An envelope feeder device is provided so as to enable a large number of envelopes to pile up. The envelope feeder device includes a body which is adjustably supported from a support shaft above the transfer conveyor, so as to position the feeder device according to the size of the envelopes. A pair of first rollers are mounted to both sides of the body and positioned so as to roll upon the upper surface of the transfer conveyor. Each first roller includes a rotary member mounted eccentrically on its side. A bifurcated feed member engages with the eccentric rotatable members so as to reciprocate horizontally as by the rotational movement of the first rollers, whereby assisting in the piling up of the envelopes as by a pair of claws located at the free ends of the bifurcated portions.

Abstract: A stripping tool particularly for fibre optic cables has flexible and resilient jaws carrying blades to contact the conductor, and when excess pressure is applied to close the blades on the conductor, the jaws can flex. This minimizes the risk of conductor damage and further, allows particularly high loading per unit area to be achieved when the blades tilt so that only the heel of each blade contacts the conductor.

Abstract: The invention relates to apparatus for inflating a continuously moving length of tubular material, in which the nozzle tube is rotatable and an arrangement is provided which locks the nozzle tube in an angular position in which the nozzle is in contact with the length of material during the discharge of gas from the nozzle.

Abstract: In a casting mould and cooling unit for use in the continuous casting of molten metal, the layers of lubricious, non-wetting material such as graphite (12) bounding the solidification chamber (10) of the mould are secured to the copper cooling jacket walls (14) through the agency of interfitting ribs and grooves (18,20) and a layer (22) of bonding material so as to afford good thermal conduction between the layers (12) and walls (14) even if a gap develops at the interface. The interfitting ribs and grooves are so shaped that each wall (14) and the corresponding layer (12) can be assembled by bringing them together facewise on. At least some of the grooves (20) are of re-entrant form to provide a mechanical key so as to reduce the possibility of a gap developing at the interface.

Abstract: An electrode holder clamps the electrode 11 in two perpendicular directions by clamp members 33 and 40. Each clamp member slidably rests on base seat 16 which has side portions 17 and 18 that extend at right angles to each other. Clamp screws 60 and 63 along with serrated engaging faces 48 and 54 and engaging members 47 and 53 allow clamp members 33 and 40 to be positioned finely, thereby accurately positioning the electrode 11. Because the respective clamp faces 37 and 44 of the clamp members 33 and 40 are formed to fit each other, even a small-diameter electrode can easily be clamped into position.

Abstract: A gauge for measuring the height of a liquid in a vessel comprises a measuring electrode (M) and a compensation electrode (R) in the vessel, and a circuit which measures the capacitance C.sub.M of the measuring electrode and the capacitance C.sub.R of the compensation electrode, each with respect to a wall of the vessel as counter-electrode, using the liquid in the vessel as dielectric. The quotient C.sub.M /C.sub.R varies with the height of the liquid in the vessel. The measuring electrode and the compensation electrode are parallel and of the same length, but differ in surface area and shape to such extent that such quotient varies as a linear function of the height of the liquid in the vessel.

Abstract: The invention relates to a method and apparatus for the automatic lubrication of the links of continuously moving material transport chains in a tensioning machine. The supply of lubricant is switched on and off for the duration of at least one complete circuit of the transport chain as a function both of the speed at which the chain goes round and the prevailing temperature in the tensioning machine, while an pulse count signal which is proportional to the speed at which the chain goes round and is used to control the supply of lubricant is multiplied by a multiplication factor formed from an actual value for the temperature, so that optimum lubrication of the chain links is provided.
