An in-line sight indicator structure for a fluid system wherein a chamber defining flow-through sight housing includes a sight glass in one wall portion thereof and a support member extending from an opposite wall portion in spaced relation to the sight glass to support an indicator element mounted thereon within a fluid stream passed through the chamber, the housing being hermetically sealed from ambient.

Connector block

A field installable device for a conventional heating and air conditioning system (HVAC) is provided which operates a blower fan in conjunction with a standard thermostat. Presently, HVAC systems operate in four modes: heating, cooling, off and fan 'on'. The device includes a multi-pole, multi-speed motor and a control operatively connected between the thermostat and the motor. With the fan switch in the 'on' position and heating or cooling called for, the control causes the blower to operate at a high speed, which may be different for heating or cooling. When the pre-selected temperature is reached the particular thermal operation (i.e., heating or cooling) is stopped. The control switches the motor to a speed substantially slower than the operating condition speed to provide continuing air circulation until the thermostat again calls for thermal operation. With the switch in 'auto' position, the blower operates similarly to present systems.

An electrical connector pin assembly including at least one conductor pin extending in sealed relation through a housing wall of a chamber and a lead wire connector block having an over-surface wall shield extending from the outer face of the connector block to surround and minimize arcing from a conductor pin end portion extending into the connector block for electrical engagement with a lead wire end.

Connector block for a terminal assembly

A heating apparatus for heating a fluid medium confined in a hermetically sealed housing chamber including a terminal assembly having a body member sealed in the housing chamber wall with pin means extending in sealed relation therethrough to provide electrically conductive inner and outer pin segments respectively connected to a heat transfer member and an electric power source, the inner pin segment means and heating element being electrically insulated from the housing wall.

Heater apparatus for fluid medium in a hermetically sealed chamber

A current resistive terminal block for connection to outer pin segment means projecting outwardly from a body member of a hermetic terminal assembly sealed in a housing wall, the terminal block including a main channel means to protect the outer pin segment means and diffuse possible leakage from the terminal assembly and subchannel means to encase and secure fused lead end wire connection means for the outer pin segment means.

Terminal block for a hermetic terminal assembly

A hermetic terminal assembly for a housing including a fuse-like area positioned in the outer pin segment of a terminal pin extending in sealed relation through the body member of the terminal assembly which body member can be sealed to a housing wall, the fuse-like area in the outer pin segment being covered with a thermally decomposable coating which in the event of decomposition includes an arc suppressant. A pin guard and lead wire end connection securing device is provided to protect the outer pin segment and to secure the lead wire end connection thereto.

A universal seal particularly for use in a lithium battery having a metal end closure, the end closure having a web with parallel planar upper and lower web surfaces and a circular opening in the web, includes an annular eyelet having substantially parallel planar upper and lower surfaces and a central aperture with a terminal pin sealed in the aperture and projecting substantially perpendicularly to the planes of the surfaces. The eyelet has chamfered upper and lower perimetric edges, symmetrically positioned about a plane parallel to and equispaced from the upper and lower surfaces of the eyelet. The eyelet is of a diameter relative to the diameter of the web opening to permit a chamfered edge of the eyelet to engage a sharp arras of the web defining the margin of the web opening in substantially line contact, intermediate the width of the chamfered edge. The closure and eyelet are then joined by a weld between the closure and the eyelet around the meeting line.
