Abstract: A deep well cooker includes a generally cylindrical cavity having peripheral and bottom walls of thermal insulating material with an electric heating element positioned adjacent the bottom thereof. A metal sleeve positioned in the cavity closely adjacent the peripheral wall extends generally at least between the heating element and the top opening of the cavity. An invertible collar supported adjacent the top opening of the cavity extends upwardly selected different distances for surrounding the upper portions of cooking pots supported in the cavity. A lid and bail assembly is mountable on cooking pots for transporting same from one location to another, and for keeping the pot contents warm.

Abstract: A floating secondary stem seal arrangement for fluid control devices which becomes operative only when fluid by-passes the primary stem seal. A secondary stem seal member is disposed outwardly along the stem from the primary seal in a secondary seal member receiving chamber. The cooperative configuration of the chamber, the secondary seal member and the stem is such that under normal operating conditions with no fluid by-passing the primary seal, the secondary seal will not perform any sealing function against the stem. Fluid by-passing the primary seal moves the secondary seal member within the secondary seal chamber axially of the stem and into a forced sealing position therewith. This selective operation of the secondary seal assures that it will be essentially free from wear during normal operating conditions and, therefore, effective for sealing purposes in the event of primary seal failure.

Abstract: A pinch tube type valve adapted to be mounted to a liquid container receiver to accept an elongated flexible outlet tube protruding from a liquid container disposed in the receiver for selecting control of liquid flow through the tube from the container. The tube is passed through a passageway in the valve body for selective engagement by a stem which is reciprocable into and out of closing engagement therewith. The passageway is enlarged adjacent the inlet end of the valve body to permit easy insertion of the liquid container outlet tube therethrough. An apertured tube retaining area is disposed adjacent the outlet end of the valve body passageway to receive and retain the tube in a desired position relative to the container receiver to facilitate ease of liquid dispensing operations. The stem may also include a tube engaging protrusion arrangement when the valve is contemplated for use in pressurized liquid systems.

Abstract: The specification and drawings disclose a gauge glass assembly including a gauge glass protected by a tubular shield including means for permitting visual observation of the gauge glass. The gauge glass is positioned in a cylindrical receptor which is in flow communication with the liquid whose level is being observed. The shield surrounds the gauge glass and has a length sufficient to enclose the exposed length of gauge glass. At the upper end of the shield an upper nut member is threadedly received on the shield and arranged such that when tightened it applies an axially directed force to drive the glass into the receptor. A lower nut member is positioned about the lower end of the gauge but is threaded to the receptor. Outwardly extending tabs or ears on the shield are engaged by the lower nut such that tightening of the nut drives the shield axially toward the receptor.
