Flat bed

P ) The system BAS 2000 (bio-imaging analyser) from Fuji Film. The system included flexible IP s, in a 20 X 40 cm and 20 X 25 cm format (type BAS ni) and an IP without proteetive layer (BAS-TR2040). With the system s laser scanner (flat bed) one can read these IP s with a resolution of 100 pm or 200 pm and a digital dynamie of 8 or 10 bits. The system is not on the market anymore. 

Several tests have been performed with the biomedical systems of Fuji Film, the BAS 2500 and BAS 5000. The BAS25(K) is similar to the BAS2000 a flat bed scatmer which can read diverse IP-sizes up to 20 x 40 cm. The read out resolution can be set up to 100 pm or 50 pm. The BAS5000, is based on a new confocal read out optic which is...

The Flat-bed pressure filter (Hydromation Engineering Co. Ltd.) (19) is based on the above principle. The pressure compartment consists of two halves, top and bottom. The bottom half is stationary while the top half can be raised to allow the belt and the cake to pass out of the compartment, and can be lowered onto the belt during the filtration and dewatering stage. The filter can be considered as a horizontal filter press with an indexing cloth in comparison with a conventional filter press, however, this filter allows only the lower face of the chamber to be used for filtration. 

Finishing and Fabrication. Since laminates are normally pressure cured in flat-bed presses and pHes overextend the plates, laminates have rough or uneven edges when removed from the press. These edges are sawed off and the back of the laminate is often sanded to improve the strength of subsequent bonding to various substrates. 

Letterpress is printed directly by the rehef method from cast metal or plates on which the image or printing areas are raised above the nonprinting areas. Ink rollers apply ink to the surface of the raised areas, which transfer it directly to paper. Flat-bed cylinder presses are available but most letterpress is printed on rotary presses. 

Reciprocating compressors are available with a large variety of other drivers, which include the piston engine, steam turbine, or, in rare cases, a gas turbine. Next in popularity to the electric motor is the piston engine. The arrangement lends itself to skid mounting, particularly with the semi-portable units found in the oilfield. The unit is also popular as a lease unit, which may be lifted onto a flat bed trailer and moved from one location to another as needed. The engine is either direct-coupled or. as with smaller compressors, it may be belt-connected. 

Conical fixed-bed adsorbers are used when a low pressure drop through the cone-shaped bed is less than one half of that through a conventional flat-bed adsorber, while the air volume is more than double that through the flat bed. 

Two-dimensional separations can be represented on a flat bed, by analogy with planar chromatography, with components represented by a series of dots . In fact, zone broadening processes in the two dimensions result in elliptically shaped spots centred on each dot . Overlap of the spots is then possible, but Bertsch (30) also showed how the contributors to the overall resolution, R, along the two axes, and Ry contribute to the final resolution according to the following ... 

As soon as the sample has been properly labeled and recorded, it should be placed in a generator-powered chest freezer located directly in the field. A flat-bed trailer can be used to transport freezers to and from the field site. Insulated boxes filled with dry-ice can be used as a substitute for freezers. However, chest freezers typically work better than dry-ice since they allow more cold air circulation around the samples, facilitating more rapid freezing. 

Embed pure polybed in beem capsules or flat-bed molds. (Spurr s embedding medium is especially suitable for plant material. If Spurr s medium is used, material can be dehydrated through EM-grade acetone, as acetone and Spurr s are compatible.)... 

Polyacrylamide gel (PAG) electrophoresis is performed either in cylindrical glass tubes or in flat beds (Figure 3.27). The method is comparable with other electrophoretic techniques but care must be taken to keep the current low to prevent any significant heating effect. 

A flat bed, without any edging, is the simplest and least labor-intensive to set up. Each corner of the bed is marked with a post, and string is tied between them to define the edge. The height of the bed relative to the paths will increase, however, if the soil is medium to heavy, and it is well dug. Soil improvers will also tend to raise it, while the paths become lower due to compaction. Flat beds are best suited to light soils, which would tend to dry out more quickly if raised up. 

Portable tanks, 1000 liter capacity these are made of mild- or heavy-duty polypropylene with a steel frame. The tanks can be delivered filled in a flat bed truck and are useful for medium-sized precast and cast on site projects. A crane or a fork lift truck is usually use to handle these tanks on site. 

The low-temperature thermal aeration (ETTA) technology is a thermal desorption process that separates chlorinated hydrocarbons, volatile organic compounds (VOCs), semivolatile organic compounds (S VOCs), pesticides, and petroleum hydrocarbons from soils at temperatures of 300 to 800° F. This technology uses hot air to desorb contaminants from soil into a contained airstream and treats the airstream before discharging it to the atmosphere. The system is transportable and consists of six major components assembled on flat-bed trailers. The entire system and support areas require approximately 10,000 ft of operating space. 

Esveld et a/.81,82 developed a continuous dry media reactor (CDMR) for pilot-scale applications. It consisted of a multi-modal tunnel microwave cavity operating at a frequency of 2.45 GHz with a power range from 0 to 6 kW irradiated on a surface of 0.6 m2. Temperatures of up to 250°C were achieved. A web conveyor travelling at 17 cm min-1 transported the solid-phase reaction mixture to the oven in low, open Pyrex supports closely packed on a polytetrafluoroethylene (PTFE)-coated glass fibre. An open flat bed process was employed to facilitate easy evaporation. 

Dansylation is often used for the determination of free and N-terminal amino acids. Dansyl chloride (5-dimethylaminonaphthalene-l-sulfonyl chloride, DNS-C1) reacts with the amino substituent of amino acids to form highly fluorescent derivatives [75,76]. The method is particularly useful for the analysis of trace components due to the high sensitivity of the products. The derivatives are usually separated by TLC on various types of layers. Separations of DNS-amino acids by flat-bed techniques have been reviewed [77]. Separations by column chromatography have been examined on polyamide [78] and Amberlite IRC-SO [79]. Although many variations of the dansylation reaction with amino acids have been reported, the one described below [77] appears to be the most common. 

After the experiment the raw data can be inspected on the oscilloscope, manipulated and finally recorded on a flat bed recorder for further use. A teletype output of all the spectral parameters provides an excellent record for later reference 17). 

Digoxigenin-labeled chromosome 10 a-satellite probe (DIOZI Oncor, Gaithersburg, MD) is used at a final concentration of 5 pl/100 pi in hybridization buffer (50% formamide, 10% dextran sulfate, 0.004% Tween 20, and standard saline citrate (SSC) [in 1.5 strength]). A 10-pl volume of the probe is placed on an 18 x 18-mm coverslip, which is placed onto the slide, sealed with special Vulcanizing Fluid, and placed on a flat-bed thermal cycler. Slides are incubated for 3 min at 94°C and placed in a humidified box for 16 hr at 37°C. 

Joyce-Loebel MK III C flat-bed microdensitometer. The structure factor magnitudes were derived from the integrated intensities according to F(hk ) 2 = I(hk ). The largest errors in the intensity measurements were for the darkest spots. The scattering factors of C, 0 H for the diffraction of electrons were taken from the International Tables for X-Ray Crystallography, vol. IV (7). No correction for multiple scattering and n-beam dynamical interactions were applied because the thickness of the crystals was of the order of 100 X (6).
