Abstract: A combination elongate soft resilient foamed polymer body, so constructed and configured as to lie along the side of the body of a human user, and a heater enclosing the polymer body, the heater being formed of fabric and including electrically insulated resistance heating lines extending substantially the length of and along the sides of the foamed polymer body, for warming a human user during sleep is disclosed.

Abstract: This invention relates to apparatus and methods for filling a conventional Bourdon tube with an outgassed fluid to permit use of the Bourdon tube to measure fluid pressures at high temperatures. The filling device includes a hot reservoir containing hydraulic fluid that has been heated to facilitate outgassing and a cold reservoir in fluid communication with the hot reservoir to prevent exposure of the fluid in the hot reservoir to oxygen. A vacuum line connected to the cold reservoir permits evacuation of the filling apparatus, the Bourdon tube and a typical bellows that may be attached to the Bourdon tube. The bellows is mechanically compressed and provided with a center post to reduce the volume of the bellows by about fifty percent. After the Bourdon tube, the bellows and the hydraulic fluid in the hot reservoir have been heated and outgassed, the vacuum is removed from the cold reservoir to permit hydraulic fluid to flow from the hot reservoir into the bellows and Bourdon tube.
