A charged particle beam apparatus comprises a transmission electron detector (113/206) that has a detecting section which is divided into a plurality of sections (201-205, 301-305), and is characterized in that it calculates the film thickness of a sample (101) by detecting, individually, the transmission electron beams (112) generated by the aforementioned sample upon irradiating the sample with an electron beam (109), as signals at each of the aforementioned sections that are in accordance with the scattering angles of the aforementioned transmission electron beams, and calculating the intensities of the aforementioned individual signals. Thus, a charged particle beam apparatus that enables an accurate film thickness monitoring with minimum errors caused by external conditions, and enables a thin film sample to be processed to an accurate thickness, is attained, enabling precision to be improved in structural observations and analysis of elements.

A process for preparing a polydiene, the process comprising the step of polymerizing conjugated diene monomer with a lanthanide-based catalyst system in the presence of a vinylsilane, an allylsilane, or an allylvinylsilane.

A rotary tumbler metal reclaimer includes an inner cylinder and a concentric outer cylinder that rotate simultaneously. The inner cylinder includes a first compartment that intakes material for breaking by teeth, a second compartment that receives broken material from the first compartment and crushes the material into smaller particles, and a third compartment wherein particulate material enters the space between the inner cylinder and the outer cylinder by attrition through perforated screens. The second compartment includes a crusher having various features for crushing lump material as it rotates. The third compartment provides further breakage and conveyance of particulate material. Particulate material then returns proximate the intake for screening into fine and coarse sizes and then collecting for reuse. Metallics and metallic oxides exit the tumbler through apertures in the rear of the third compartment for collection. The tumbler reclaims metals, metallic oxides, sands, and other materials for reuse.

Conventionally, either the moving blades of a steam turbine are provided with grooves extending in the blade-length direction and the upper edge of the blade was configured so as to coincide with the end surface of the blade cover, or holes were formed in the blade cover in order to remove the moisture adhering to the blade. However, increasing the number of grooves increases the surface area connecting the outside and the inside of the blade cover and results and greater steam loss. In order to resolve this problem, a tip cover (3) is provided on the tip of a blade (1), and a drain guide groove (4) is provided on the moving blade-side side surface of the tip cover (3). Moisture trapping grooves (2) provided on the blade (1) extend in the length-direction of the blade, and the drain guide groove (4) is positioned above the moisture trapping grooves (2). The drain guide groove (4) is connected to a moisture spout (5) provided on the tip cover (3). The moisture adhering to the blade (1) moves through the moisture trapping grooves (2) and the drain guide groove (4) to be ejected from the moisture spout (5) into a drain pocket (7). Such a constitution allows the elimination of moisture adhering to the blade (1) via a single moisture spout.

Method of distillation of liquid waste, mainly of waste oils, designed so that the liquid waste is fed into a falling film evaporator, in which distillation occurs from the thin liquid film moving downward by the action of gravitation, whereby vapours created at heated inner wall are collected at pressure 0.1 to 110 kPa and vapour temperature from 80° to 330°. The said falling film evaporator, be it of atmospheric or vacuum design, consists of a single, vertically disposed hollow distillation body (5) with inner evaporation surface (6), furthermore of a heated block (4) with heat being transferred to the outer heated surface of the hollow distillation body (5).

A tantalum powder, a preparation method thereof and an electrolytic capacitor anode made of the tantalum powder are provided. The tantalum powder has BET surface area of not more than 0.530 m2/g and Fisher average particle size of not less than 3.00 μm. The method of preparing the tantalum powder is provided, wherein the tantalum powder is prepared through reducing tantalum compound with a reducing agent. The method is characterized in that a tantalum powder is added as seed during reduction, and said seed of tantalum powder is the tantalum powder that has been milled.

A process for the catalytic dehydrogenation of a C3+ feed hydrocarbon. The hydrocarbon feedstock is initially divided and a first portion of the feedstock is introduced into a first dehydrogenation reaction zone operated without oxidative reheat and the resulting effluent is introduced into a second dehydrogenation reaction zone operated without oxidative reheat. The resulting effluent from the second dehydrogenation reaction zone is introduced along with a second portion of the feedstock into a third dehydrogenation reaction zone operated with oxidative reheat.

The invention relates to an apparatus (2) for transporting and changing the positions of at least two workpieces (W; W1 – W4) between and/or in machining stages (I, II) of a machining system (1), comprising a traverse member (9) that can be moved between the machining stages (I, II), a first beam (10) for a first holding apparatus (10a) for the first workpiece (W; W1), said first beam being movable with respect to the traverse member (9), and a second beam (11) for a second holding apparatus (11a) for the second workpiece (W; W2), said second beam being movable with respect to the traverse member (9). The second beam (11) can be moved by the first beam (10).

The invention is sealing plastic accumulator cover used in accumulators (1) so called as maintenance-free accumulator (1) having a secondary cover (4) on the body cover (3) and it is characterized in that it consists of at least one locking clamp (4.1) located on the said secondary cover (4) in order to provide fixing the said secondary cover (4) onto the said body cover (3) without use of welding and/or hot adhering, at least one clamp housing (3.1) located on the said body cover (3) and housing the said locking clamp (3.1), at least one sealing member (7) located between the said secondary cover (4) and the said body cover (3) in order to provide inner and/or external sealing of the said secondary cover (4) and the said body cover (3).
