Apparatus processors

In the electrocurtain processor, the shielding is clad direcdy to the tube housing. Housing space is relatively small, because a shielded tube 25 cm in diameter replaces the 3-m high stmcture required for the scaimed electron beam apparatus. The electrocurtain has a more flexible geometry and can be adapted more readily to many different types of curing appHcations (43). 

Commercial autonomic apparatus with microprocessor technology, but with more emphasis on routine analysis, also became available, viz., the Metrohm 646 VA processor and the PARC Model 384B polarographic analyser the main features of these are worthy of brief consideration here. 

Remember also, that, as pointed out by Blass and Halsey (1981), deconvolution can be used to achieve resolution otherwise unavailable or to obtain a specific required resolution using hardware with a factor of 2 to 3 less in resolving power. To the dedicated experimental scientist this may sound like heresy. We are sure that in 1984 such reactions are not uncommon in 1994 it is likely that most observational devices will have a deconvolution processor imbedded in them and that the deconvolution processor will, in fact, be thought of as an integral part of the experimental apparatus.

The instrumentation for TP investigations is relatively simple the set-ups for TP reduction (TPR) and TP oxidation (TPO) studies of catalysts are shown in Figure 2.1. The reactor, charged with catalyst, is controlled by a processor, which heats the reactor at a rate of typically 0.1 to 20 °C min-1. A thermal conductivity detector measures the hydrogen or oxygen content of the gas mixture before and after reaction. For TPR, one uses a mixture of typically 5% H2 in Ar, or for TPO 5% 02 in He, to optimize the thermal conductivity difference between reactant and carrier gas. With this type of apparatus, a TPR (TPO) spectrum is a plot of the hydrogen (oxygen) consumption of a catalyst as a function of temperature. 

DSC(3) data were obtained with a Model DSC-200 apparatus (Seiko Instruments Inc.) at the Koriyama Plant of Nippon Peroxide Co., Ltd. The sample cell used was a sealed cell supplied from Seiko Instruments Inc. Tdsc(3) and Qdsc(3) were determined directly by the processor supplied with a DSC apparatus. 

DSC(4) data were obtained with a Model DSC-910 DSC apparatus (Du Pont) at Morisaki s laboratory, Research Institute of Industrial Safety 11. This apparatus was a thermal-flux type pressure DSC apparatus. Data were obtained in argon atmosphere at 3.5MPa. The sample cell used was a pin-hole aluminum cell. Data was processed by the processor supplied with the DSC apparatus. 

Industry uses special devices similar to ultrasonic baths and probes but appropriately scaled up in size and ultrasound irradiation power. The UIP16000 model from Hielscher Ultrasound Technology is by far the most powerful ultrasonic processor available worldwide the apparatus is capable of delivering a continuous power of 16000 W at efficiency above 80%. Such powerful systems have been developed in response to the demand for the ultrasonic treatment of liquids on a large scale in fact, the ultrasound power required usually increases in proportion to the amount of liquid to be treated within a certain time. 

The apparatus used, with slight modifications, is the same for both experiments. The processor is a DEC LSI 11/3 with 64K bytes of RAM. Communication with the processor is done using a CRT terminal. A pair of double-density, flexible-disk drivers are used for storage of software and data. Other system components include a 1 MHz programmable timer, 12-bit A/D and... 

Another multistage fluidized bed processor is depicted in Fig, 7.76. It is a rectangular apparatus in which the different chambers are separated by walls with transversely arranged connections or (as shown in Fig. 7.76) openings at the bottom, close to the gas distribution plates, both providing plug flow. Although in the sketch a common...

Some of the agar-containing seaweed is collected from rocks exposed at low tide along the sea coast of Japan, but the best material is collected under water by specially trained female divers, called Ama. Male divers, equipped with diving apparatus, make the collections at depths greater than 60 feet. The algae is sold to commercial processors after it has been dried and partly bleached on the beach. 

Later developments by the Mettler Company include a desktop thermogravimetry apparatus, the TA 4000. This system consists of a computer processor (TCIO A) and the thermobalance, shown in schematic cross section in Fig. 7.4. The readability of the balance is 1 ng. The electrical range of mass compensation is from 0 to 150 mg, and the overall capacity of the balance is 3,050 mg. The temperature range is room temperature to 1,250 K with heating rates of 0 -100 K/min. The TA 4000 system also includes tabletop modules for DSC and TMA, all coupled to the same data processor. 

Apparatus. The experiment was conducted on a Dell Inspiron 630m laptop with 1.6 GHz Intel Centrino processor and 1 GB of RAM running the Windows XP Home operating system. The resolution of the 14.1 LCD was 1280 by 800 pixels. The experiment was conducted in full screen mode, with the user s head situated about two feet from the screen. A noise-canceling headset microphone (Altec Lansing AHS322) was used for audio input.
