Abstract:
A method is provided for carbonizing and activating carbonaceous material, which comprises supplying the material to an externally fired rotary kiln maintained at carbonizing and activating temperatures, the kiln having a downward slope to progress the material as it rotates, the kiln having an atmosphere substantially free of oxygen provided by a counter-current of steam or carbon dioxide, and annular weirs being provided at intervals along the kiln to control progress of the material. There may further be provided an externally fired rotary kiln for carbonizing and activating carbonaceous material having a hollow rotary body that has a downward slope towards a discharge end thereof, and which is provided at intervals along its length with annular weirs for controlling progress of the carbonaceous material. In embodiments, there is also provided a process is for producing discrete solid beads of polymeric material e.g. phenolic resin beads having a mesoporous structure, which may be useful as feedstock for the above mentioned carbonization/activation process or which may have other utility e.g. as ion exchange resins. The process may produce resin beads on an industrial scale without aggregates of resin building up speedily and interrupting production. The process comprises the steps of: (a) combining a stream of a polymerizable liquid precursor e.g. a novolac and hexamine as cross-linking agent dissolved in a first polar organic liquid e.g. ethylene glycol with a stream of a liquid suspension medium which is a second non-polar organic liquid with which the liquid precursor is substantially or completely immiscible e.g. transformer oil containing a drying oil; (b) mixing the combined stream to disperse the polymerizable liquid precursor as droplets in the suspension medium e.g. using an in-line static mixer; (c) allowing the droplets to polymerise in a laminar flow of the suspension medium so as to form discrete solid beads that cannot agglomerate; and (d) recovering the beads from the suspension medium. There is also provided apparatus for forming discrete solid beads of polymeric material, said apparatus comprising: a first line for conveying s stream of a polymerizable liquid precursor; a second line for conveying a stream of a dispersion medium with which the polymerizable liquid precursor is substantially or completely immiscible; an in-line mixer configured to receive a combined flow from the first and second lines and to disperse the polymerizable liquid precursor as droplets in the dispersion medium; a vertical polymerization column configured to receive the dispersion medium with the droplets dispersed therein and to permit the polymerizable liquid precursor polymerize while descending the column in a descending flow of polymerization medium; and a vessel at the base of the column for receiving the descending flow of dispersion medium and collecting polymerized solid beads.
Abstract:
An adjustable threading tool assembly. A cutting insert holder is adjustably held in a pocket in a toolholder. The cutting angle of the insert can be set by selecting a precision ground washer that sets the position of a retaining bolt that holds the insert in the pocket such that the desired angle is provided.
Abstract:
A cutting tool assembly (14) including a tool holder (20) having a removeable clamp (20a). A cutting insert support blade member (16) is removably held in the tool holder by the clamp (20a). The cutting insert support blade (16) includes at least one, preferably two, insert receiving pockets (30). The pockets (30) are defined by a body portion (16b) and a clamp portion (16a) joined together by an integrally formed resilient or deformable portion (16c) which permits slight resilient movement between the clamping and body portions to facilitate the installation of a cutting insert (18) in a pocket. When the insert support blade (16) is mounted in the tool holder (20), the clamp inserts clamping forces to the clamping portion (16a) of the insert support blade which serves to secure the insert support blade to the tool holder and exert clamping forces on an insert (18) held in the pocket. The integrally formed resilient/deformable portion (16c) includes a plurality of slots (50, 52, 50′, 52′), some of which open into an aperture (54) spaced from a pocket (30). The slots enable resilient movement between the clamping and body portions.

A regenerable adsorber for removing VOCs from gas streams consists of a porous monolithic carbon which can be regenerated by heating by passing an electric current through it.
Abstract:
In some examples, a meeting table structure comprises a first portion comprising a horizontal top comprising an upper surface forming a working area, a second portion, removably attachable to or provided as in integral part of the first portion, the second portion comprising a cavity defining a housing, the cavity being acoustically and/or thermally insulated from the first portion and acoustically and/or thermally insulated from the surrounding environment, and a chassis structure provided in the housing, the chassis structure configured to support a short-throw optical projection system, the chassis structure further comprising an arm configured to extend above the upper surface of the horizontal top of the first portion and configured to receive a camera apparatus and/or a speaker apparatus.
Abstract:
A handheld tissue stretching device combined with an extremity flexibility number, stretchscore, enables users to independently evaluate and treat the flexibility of their extremity tissue minimizing physical therapist intervention to evaluate and treat tissue. The distance between handheld stretching devices and the extremity supports changes with a high degree of variability during home treatments; whereas, medical professionals monitor stretch intensity visually and manually. Patients performing home-based stretches impart variable intensity that leads to inconsistent tissue treatment resulting in increased tissue stiffness. The present inventors have discovered when the slack is automatically retracted, the distance between the users hands and the extremity support is continuously proportional to the flexibility of the extremity. This “distance matching” between the handheld stretching device and the extremity support provides a reliable, repeatable, and independent evaluation of extremity flexibility by directly relating this change in distance to the user's flexibility.
