Abstract: An expendable closure assembly is provided for use (in multiple units) with a lockable pressure vessel cover along its rim, such as of an autoclave. This assembly is suited to variable compressive contact and locking with the vessel lid sealing gasket. The closure assembly consists of a thick walled sleeve insert for retention in the under bores fabricated in the cover periphery and the sleeve is provided with internal threading only. A snap serves as a retainer on the underside of the sleeve, locking it into an under bore retention channel. Finally, a standard elongate externally threaded bolt is sized for mating cooperation with the so positioned sleeve, whereby the location of the bolt shaft in the cover bore hole determines its compressive contact on the underlying gasket.

Abstract: An autoclave useful for pressure digestion of samples for chemical analysis, consisting of a closeable vessel containing the sample, which during operation sustains elevated temperatures and pressures. The autoclave has a PTFE (Teflon) beaker and lid, in direct contact with each other thus forming a tight seal with an excess-pressure release mechanism. The assembled vessel is held in a device that presses the sealing surfaces of the beaker and lid together, through pressure on a metallic lid support disc. The sealing surfaces of the beaker and lid are free-standing, which permits a direct release of excess-pressure and necessitates an extended clamping device for the lid support disc, which is fixed at a single point.

At least one wall of the chamber has at least one opening through which the workpieces or objects can be introduced or removed. The opening can be closed by means of a closing member including a sealing member which acts together with a sealing surface. The sealing surface is arranged within the chamber laterally of the opening. A circumferentially closed sealing member arranged on the closing member rests against the sealing surface in the closed position of the closing member. The sealing surface has imaginary straight generatrices which extend parallel to the axis of the opening of the chamber. The sealing surface has at least two sealing surface portion which are lateraly offset from each other relative to the axis of the opening and which are connected to each other at opposite locations. The sealing member has sections of different lengths and/or shapes which are located in different planes. Two principal sections of the sealing member are located in planes which extend perpendicularly to the axis of the opening. The two principal sections are spaced apart from each other and are connected by lateral sections. The closing member has a surface which carries the sealing member and corresponds in shape to the sealing surface. The closing member is slidable in the wall of the plane and parallel to the plane of the opening.

Abstract: An improved, low cost, energy efficient extrusion device and method for processing of cellulose, hemicellulose, and like fiber-bearing materials is described which includes a pretreatment extrusion zone and a reaction extrusion zone separated by a pressure sensitive variable die. The method hereof includes the steps of extruding cellulosic material through the pretreatment zone at an elevated pressure and temperature, passing the material into the reaction zone where it is mixed with an acid and is processed at a lower pressure and temperature than in the pretreatment zone, and extruding the material through a final extrusion die. The surging and blowing usually experienced with extrusion of fibrous material is drastically reduced by the unique construction of the extruder die members. The cellulosic material may be hydrolyzed to simple sugars in accordance with the method and apparatus hereof with a minimum of acid degradation of the extrusion equipment. The sugars produced from the cellulosic material may in turn be converted into ethanol or other usable fuels by the process of fermentation.

Abstract: A process and apparatus for the acid hydrolysis of waste cellulose to glucose of the type wherein waste cellulose is continuously fed into an inlet port of a twin screw extruder, water is continuously fed into reaction zone in the extruder, downstream of the inlet port, the cellulose is continuously reacted with water in the presence of an acid catalyst at elevated temperature and pressure in the reaction zone while being continuously conveyed to an outlet port of the extruder having a given diameter and the reacted cellulose is discharged from the extruder while the elevated temperature and pressure in the reaction zone is maintained. The elevated pressure is maintained by forming a dynamic seal zone at the upstream end of the reaction and continuously discharging the reacted material downstream of the outlet port at a predetermined volume rate of flow to maintain the pressure by passing the discharge through an orifice pipe having a smaller diameter than the given diameter of the outlet port.
