摘要： An apparatus for impregnating tobacco with an expansion agent includes a chamber for confining a charge of tobacco under elevated pressure conditions. An accumulator connected to the chamber maintains a supply of an expansion agent in fluid form under conditions of elevated temperature and pressure but less than the desired tobacco impregnation temperature and pressure. The expansion agent is forcibly and rapidly moved from the accumulator and introduced into the chamber under conditions such that the pressure and temperature of the expansion agent are increased to the desired impregnation temperature and pressure, preferably including a pressure approaching or above the supercritical pressure thereof.

摘要： A weed pulling device designed to apply a substantially vertical force to the stem of a weed engaged by the device comprises a tubular body having a first end that is bifurcated to provide two opposing members having edges that define two cooperating V-shaped slots or openings positioned in confronting relationship. One of the V-shaped slots or openings is designed to engage and retain the stem of a weed while the second V-shaped slot or opening is designed to contact the stem of the weed in a non-cutting manner as the device is manipulated to cause the weed stem to wrap around the bifurcated end of the tubular body. Also disclosed is a modification that additionally includes an elongated tine offset from an associated collar that is mounted on the side of the tubular body to provide sufficient space between the elongated tine and the tubular body to engage the stem of a weed in that space preparatory to wrapping the weed stem around the device by rotating it so that a pulling force can be applied to the stem of the weed.

摘要： An apparatus for recovering vapors used in a processing system which expands tobacco to increase its filling capacity, including a tank having a supply of condensable compound in its liquid state and a less dense chilling liquid which is maintained at a temperature below the boiling point of the condensable compound and floats thereon. The upper portion of the tank is segregated into a condensor section which receives the vapors from the processing system and a compressor section for maintaining a selected pressure in the tank. A sparging header is provided within the chilling liquid to receive and introduce the vapors of the compound in the condensor section of the tank so that the vapors will be condensed and settle to the bottom of the tank.
摘要翻译：一种用于回收用于扩展烟草以增加其填充能力的处理系统中的蒸气的装置，包括具有其液态的可冷凝化合物供应的罐和不太致密的冷却液体，其保持在低于可冷凝化合物和漂浮在其上。罐的上部被分离成从处理系统接收蒸汽的冷凝器部分和用于保持罐中选定压力的压缩机部分。在冷却液体内设置有喷射头，用于接收和引入化合物在罐的冷凝器部分中的蒸气，使得蒸气将被冷凝并沉降到罐的底部。

摘要： A process and apparatus for tobacco expansion is employed for expanding tobacco at rapid throughput rates. The apparatus includes a spool and shell assembly wherein the spool is moveable into and out of the shell between loading, impregnating, and unloading positions. In the impregnating position, sealing assemblies seal the radial clearance between the spool and shell to provide a pressure vessel for tobacco impregnation. The sealing assemblies include at least one elastically deformable sealing ring and an annularly shaped axial pressure applying member to releasably impart axial pressure to the sealing ring. The axial pressure applying member receives fluid pressure from a hydraulic fluid and preferably receives additional fluid pressure from the expansion agent used to expand the tobacco.

摘要： A process and apparatus for tobacco expansion is employed for expanding tobacco at rapid throughput rates. The apparatus includes a spool and shell assembly wherein the spool is moveable within the shell between loading, impregnating, and unloading positions. In the impregnating position, sealing assemblies seal the radial clearance between shell and the end members of the spool to provide a pressure vessel for tobacco impregnation. The sealing assemblies includes at least one elastically deformable sealing ring associated with the circumferential exterior of the end member. A pressure applying member is operatively associated with an axial end of each of the sealing members to releasably impart axial pressure onto the axial end of the sealing member when the spool is in the treating position to cause radial expansion of the deformable sealing ring and thereby accomplish sealing of the spool within the shell.
