Abstract: A temperature probe for measuring temperatures in a fluid contains a temperature responsive electrical element partially encased by a sapphire encasement. The sapphire encasement and the electrical element are further partially encased by a ceramic encasement that is exposed to the fluid. The ceramic encasement is permeable to certain gases to which the sapphire encasement is impermeable. A series of seals in the temperature probe prevents fluid from exiting through the temperature probe if the ceramic encasement and sapphire encasement are breached.

Abstract: Automatic Production, filling, and closing of bags, especially plastic guted bags. The bag is produced at a first station of the apparatus for carrying out the invention, from a flat tube. The bag is then successively moved to a second station where it is filled, a third station where it is sealed or closed, and a fourth station at which it is transferred from the machine to a delevery point which may be outfitted with a conveyor for transferring the filled and closed bag to a storage area.
