Abstract: A liquid level signaling electrical switch operated by a float protected within a container in the tank being monitored for level so that only slow changes in level are allowed to influence the float position thereby substantially eliminating flickering of the signal lamp upon sudden changes in tank level at the float due to bump vibration, hill angulation, turns, and sudden starts and stops shifting the liquid in the tank off true gravational level. The float closes the switch at substantially true refill level by locating a magnet closer to an armature when the switch closes so that the magnet exerts strong magnetic force holding the switch closed thus also preventing flickering of the signal lamp. The float container and switch are integrated in a removable assembly together with a liquid supply tube, filter foot, and base connector so that complete assembly of parts is feasible outside the tank obviating separately installing parts in the tank.

Abstract: Apparatus for sealably interconnecting a plurality of tubes between systems enabling complete manufacture of one portion of a system with associated tubes separately from the other portions of a system facilitating complete manufacture of sub-assemblies and easy accurate interconnection upon final assembly. The apparatus includes a multiple tube connector resilient block and clamp bar for one sub-assembly. The block is sealably connected on a base plate which connects the block and tubes to a device which uses and/or controls the channeling between the tubes connected thereto. The apparatus seals the channels opening through the face of the resilient block in which the tubes are sealed against the relatively non-resilient base plate surface in alignment with ports in the base plate.
