A fluid filter cartridge is disclosed herein. The filter cartridge includes a generally tubular casing closed at one end and having at the opposite, open end, an annular member defining a filter element receiving aperture and provided with a single seal extending circumferentially of the casing and projecting axially away from the casing. The filter element includes a base ring and a generally tubular filter screen extending from the base ring to an end closure therefor. The base ring and tubular filter screen are dimensioned to fit within the filter receiving aperture. A removable connection is provided between the annular member and the base ring whereby the filter element is removably retained in the casing after rotation of the filter element about its axis relative to the axis of the casing.

Spin-on filter assembly incorporating a re-usable tubular filter screen

A fusible solder temperature sensor adapted for use with a trapped fluid pressure header alarm system. The sensor includes an insulating plastic fitting having threads at one end and a bore therethrough for connection to and fluid communication with the header system. A brass tube is connected at one end to the other end of the plastic fitting for fluid communication therewith. The other end of the brass tube is closed by a bronze closure disc attached thereto by fusible solder responsive to ambient air or other gas temperature above a determined level. When the ambient temperature reaches the determined level, the solder melts, releasing the closure disc from the tube, thereby releasing pressure from the alarm system to generate an alarm signal or the like.
