Used equipment suppliers

It is possible to build a basic system with chart-recorder output using components from various manufacturers. Suppliers of used equipment are another possible source. Sometimes there are equipment auctions but, having learnt from bitter experience, unless one can actually go and see (and preferably test) the items listed in the catalogue, this method of purchase should be avoided. Very often parts will be missing and, being obsolete, no longer obtainable. Used equipment suppliers always include some form of guarantee, and that is worth its cost. Some used or refurbished equipment suppliers are listed in Appendix 1. 

Manufactured by Bausch Lomb Optical Co., Rochester, NY, Catalog No. 33-45-03. All Instrument terminology used in this method corresponds with that used in the Reference Manual supplied with the instrument. Production of this refractometer was discontinued in 1976. However it may be obtainable from instrument exchanges or used equipment suppliers. If other available instrumentation is used, the precision statements of Section 13 will not apply. 

The Abbe-type precision refractometer is no longer available but may be obtainable from instrument exchanges or used equipment suppliers. Other precision refractometers may be suitable, but they have not as yet been tested cooperatively. 

List the major types of air pollution control devices used for particulate removal. Visit the Web and make a list of equipment suppliers for these hardware. 

A final empirical expression that can be used is given below. This equation relates pressure drop to fabric properties which are readily obtainable from equipment suppliers. 

Take the results for questions 4 and 5 and do a comparative cost analysis. First go the the Web and find suitable equipment suppliers that will provide the equipment in the size ranges you have calculated. Obtain some vendor quotes (rough ones will do). Then perform the fowllowing analysis (a) What are the comparative costs between the two oprions for energy use (b) What are the comparative costs between the two options in terms of maintanance and labor costs (c) Can you combine both equipment options into a single process, and if so, can you justify this and how Assume in the above that the reduction in solids concentration must meet the 1 % weirht criteria described in question 4. 

In some cases equipment suppliers and tradenames are noted, however these citations should not be considered an endorsement of products or services. They are cited strictly for illustrative purposes. Also recognize, that neither I, nor the publisher guarantee any designs emanating from the use of resources or discussions presented herein. Final designs must be based upon strict adherence to local engineering codes, and federal safety and environmental compliance standards. 

The standard requires the supplier to use equipment in a manner which ensures that measurement uncertainty is known and is consistent with the required measurement capability. 

Some of the larger sizes, 22 in. and up, are used for special situations. Also, some of the non-standard process sizes such as 2X in., 3X in. and 5 in. are used by packaged equipment suppliers to connect components in their system for use in processes such as refrigeration, drying, or contacting. 

For all materials other than basic constructional steels and cast irons, reputable suppliers have information bases and applications laboratories from which information can be obtained. Trade organizations representing categories of materials suppliers are excellent sources of information some are listed at the end of this chapter. The materials suppliers should be consulted in conjunction with equipment suppliers in order to ensure that the information generated is fully applicable to the end use to which the material is to be put. Fabrication techniques should be agreed between the two types of suppliers, since some materials cannot be cast or welded and forging cannot make some items. 

In the design of equipment for the manufacture of sterile ophthalmic (and nonophthalmic) pharmaceuticals, manufacturers and equipment suppliers are turning to the advanced technology in use in the dairy and aerospace industries, where such concepts as CIP (clean-in-place), COP (clean-out-of-place), automatic heliarc welding, and electropolishing have been in use for several years. As a guide here, the reader is referred to the so-called 3A Standards of the dairy industry issued by the U.S. Public Health Service [267],...

Model is more complex and besides user and producer of the chemical also the equipment supplier with its specific process know-how is involved in the process. In this model the chemical producer together with the equipment supplier offer a solution that has been improved with regard to efficiency of chemicals and energy use. The user pays for the benefit of the complete solution and further improves efficiency of the offered solution related to its process. 

The greatest change in test laboratories in recent times, and rubber is no exception, is the improvements made to apparatus by the introduction of more advanced instrumentation and automation, in particular the application of computers both to control tests and to handle the data produced. These developments can and do influence the test techniques which are used and this is discussed in Chapter 2 Section 6. Also, whenever appropriate, comment is made on the form of apparatus now available for any particular test and there is a guide to test equipment for rubbers and plastics in a test equipment suppliers directory4. 

Information contained and condensed in this book has been collected from many sources. Included is the extensive information assembled from worldwide personal experience, industrial, and teaching experiences of the two authors totaling over a century. Use was also made of worldwide information from industry (personal contacts, material and equipment suppliers, conferences, books, articles, etc.) and major trade associations. For someone to collect this information would require the person having familiarity in the many facets involved in the plastic industry worldwide. 

Electrical equipment. Fuel cell power in the form of direct current at low potential difference will usually need to be adapted to practical use, by conversion to alternating current at, say, 110 V, 60 Hz or 230 V, 50 Hz. Two main inverter equipment suppliers have their web sites listed at the end of the book, namely the Asea Brown Boveri Group, suppliers to Ballard Power, which has most of the fuel cell market, and Xantrex Technology Inc. Ballard is just entering the market, see Ecostar below.
