An assembly comprising a tap plug having therein an axially fixed nut and including an externally threaded portion threaded into a cable connector lug, a bushing having therein an internally threaded bore, and a stud including an externally threaded first end threaded into the nut, and an externally threaded second end threaded into the bushing bore.

A differential pressure controller includes means for controllably metering a flow of air therethrough to an external control device, the metering means including a valving member and a nozzle coacting with the member for metering the flow of air. Also included in a plurality of diaphragms coacting with the valving member and defining a first chamber for receiving a first pressure signal and a second chamber for receiving a second pressure signal. One of the pressure signals includes a component representative of a master control signal. Metering of the flow of air is in response to a pressure difference between the first pressure signal and the second pressure signal.

Pneumatic differential pressure controller

A level detecting device for detecting the level of liquid in a tank includes a displacer or float displaceable in response to the level of the liquid in the tank, an enclosure tube disposed on the tank and sealed thereagainst so that the exterior of the enclosure tube is isolated from the liquid in the tank and a variable transformer for detecting the displacement of the float. The transformer includes at least two windings disposed adjacent the outside of the enclosure tube and an elongate core disposed within the enclosure tube and coupled to the float so as to be movable therewith, the amount of magnetic coupling between the windings being dependent upon the position of the core in the enclosure tube. Means are provided for generating an output signal representing the amount of magnetic coupling between the windings to derive an indication of the level of the liquid in the tank. Since the float and core are isolated from the balance of the apparatus by the enclosure tube, the liquid cannot adversely affect the components of the detector, and hence the life and reliability of the apparatus is extended.
