The tube is an endotracheal tube including up to three lumens, in addition to the primary lumen, which serve various functions to provide versatility in the treatment of patients. In cuffed tubes one of the lumens is used for inflating the cuff once the tube has been placed in the desired position in the trachea of the patient....

Improved hydrophilic crosslinked polyurethane foams are prepared by reacting (a) an isocyanate-capped polyoxyethylene prepolymer with (b) at least 20 moles of water per mole of NCO groups in the presence of (c) alumina hydrate, (d) a phosphorus fire-retardant additive and (e) an organic carbon compound which serves to react with phosphate anions at high temperatures (e.g., in the presence of a fla...

A combined nozzle for air and fuel to a fluidized bed (20) comprises two fixed portions (1, 10) mounted at the top and bottom of an air chamber (4) and a movable, withdrawable portion (2) which connects the two fixed portions and is guided by them. The movable portion blocks the lower fixed portion (10) outwardly and conducts air and fuel to the upper fixed portion (1). Further, there is a device ...

A sprung brake apparatus including a casing in which is mounted a plunger (33), which on its one side is joined to a spring chamber and on the other is connected to a rod (42,62). The spring (21) is arranged in the spring chamber so as to press the plunger and thereby the plunger rod axially away from the spring chamber in order to apply the brakes. The spring is designed to work essentially acr...
