A compensator for a pressure operated fuel regulator comprises a housing having an opening for bleeding air therethrough. There is a tapered plug in the opening fastened to a thermostatic metal within the housing. When the thermostatic metal is heated by incoming air, the clearance around the plug in the opening increases, and the amount of air bleeding out of the opening increases.

Temperature compensator for pressure operated fuel regulator

A temperature compensator for a pressure operated fuel regulator is used in combination with a heat recuperator to regulate fuel flow. In the recuperator, air to be used for combustion of the fuel is heated. Some of the heated air is supplied to the compensator, which comprises a housing having an opening for bleeding air therethrough. The rate of bleeding through of the air, and consequently the pressure drop across the compensator, is dependent on the temperature of the air supplied to the compensator.

Heat recuperator with compensator for pressure operated fuel regulator

A multi-pass ceramic recuperator includes a temperature compensator mounted within the gaseous flow of an intermediate pass. The compensator includes a bleed valve actuated by a temperature sensitive mechanism which is mounted outside the compensator body and directly in the gaseous flow.

Europium and ytterbium when added to terbium-activated rare earth phosphors having either a lanthanum oxysulfide, gadolinium oxysulfide, or yttrium oxysulfide host increase the decay period of the phosphors in a controlled manner.

Terbium-activated rare earth oxysulfide phosphors with controlled decay

Terbium-activated rare-earth oxysulfide X-ray phosphors containing small amounts of cerium exhibit shorter decay times than the same materials without cerium. X-ray intensifying screens employing such phosphors enable improved resolution.

Terbium-activated rare earth oxysulfide X-ray phosphors

An orange broad-band emitting phosphor is a titanium-activated lanthanum oxysulfide containing up to about 0.05 moles of titanium per mole of lanthanum oxysulfide host. The phosphor is prepared by incorporating titanium oxide in the desired ratio to lanthanum into the mixture at the time the lanthanum is sulfurized in the presence of an alkali metal carbonate, to form lanthanum oxysulfide.
