Abstract: An apparatus and method for determining the dielectric constant and/or resistivity of an earth formation which is subject to invasion of fluid, for example drilling fluid from a borehole. A transmitter (17) transmits electromagnetic energy at about 20 Mhz. from a first location in the borehole. Three receivers (22, 23, 24) are spaced at locations successively further away from the transmitter. Secondary field ratio means (140, 154, 154A, 168, 170) derives the ratio of the magnitudes of the secondary electromagnetic field at the two nearest of the three receivers, and a phase difference means (130) derives the phase difference between the received energies at the two furthest of the three receivers. The dielectric constant and the resistivity are determined from the secondary field amplitude ratio and the phase difference. The use of the secondary field ratio improves the depth of investigation.

Abstract: A retarder or brake mechanism (20) for controlling the velocity of articles on a gravity conveyor (10) has a pneumatically operated actuator (44). During each cycle of operation of the brake a charge of air of limited volume is supplied to the actuator, which has an air bleed (51) which limits the actuator's period of action during each cycle. The charge of air is supplied by an accumulator (45), which is normally connected to a source of compressed air. An article actuated sensor (31, 31a) and connected valve (30), upon being tripped by an article, isolates the accumulator from its air supply and connects it to the actuator activating the actuator but limiting its air supply to the charge stored in the accumulator before the valve was shifted by the sensor. The charge, once exhausted, is not replenished until the sensor is released by the article.

Abstract: A filter for arresting debris of a predetermined size range from a fluid path has a first face disposed transversely in the fluid path and a second face disposed substantially parallel to the first face and displaced therefrom in the direction of fluid flow. The displacement of the second face from the first face substantially defines the strength of the filter with respect to deformation by the fluid flow. The first and second faces cooperate to define a plurality of apertures extending through the filter. The apertures are of a size to preclude passage of the debris while presenting a predetermined resistance to the fluid flow. That predetermined resistance is substantially independent of the filter's strength.

Abstract: In electrical resistance welding apparatus comprising two welding electrodes (E<sub>1</sub>, E<sub>2</sub>) connected through respective supply cables (C,, C<sub>2</sub>) to an electrical power supply (P) which can generate welding currents (i) with selectively-variable rms values, a control device (1) is provided which, in use of the apparatus, measures the resistance between the electrodes (E,, E<sub>2</sub>) clamped on the pieces (P) which are being welded and the resistance between the ends of the supply cables (C<sub>1</sub>, C<sub>2</sub>). During welding, the device detects the change in the resistance between the electrodes (E<sub>1</sub>, E<sub>2</sub>) with time and, on the basis of a linear combination of several parameters of the resistance curve detected, establishes whether the spot weld effected should be considered acceptable or unacceptable. In the latter case, the control device causes the welding operation to be continued with a current having a higher rms value so as to correct the spot weld made. A statistical analysis is carried out on the spots considered acceptable so as to effect, in dependence on the results of this analysis, gradual increases in the duration of the activation intervals (welding angle) of the electrical power supply (P) so as to compensate for the wear of the electrodes (E,, E<sub>2</sub>). A gradual increase in the duration of the activation intervals of the electrical power supply is also effected upon an increase in the resistance detected between the ends of the supply cables (C<sub>1</sub>, C<sub>2</sub>) in order to compensate for the wear of the cables themselves. Once the possibility of correction has been exhausted, the device (1) indicates to the exterior (42, 43, 44) the need to replace the electrodes and/or the supply cables.
