Taken from About this Guide: The reliable operation of linear motion elements depends on selecting the right lubricants for the particular conditions of use.
A lubricant has to reduce friction and wear, provide protection from corrosion and soiling.
Lubricant has a decisive impact on the operation and service life of linear guides. A shortage of lubricant or the use of an unsuitable lubricant are often the cause of linear guide failure.
The choice of suitable lubricants requires careful consideration during the design, operation and servicing of linear guides. It depends above all on the operating temperature range and the environmental and operating conditions at the point of use. Consideration must also be given to the type of lubricant supply.
Most linear motion elements work with grease or oil lubrication. Oil/air lubrication is used in some cases.
This Lubrication Guide is generally valid for all STAR products. No distinction is made, therefore, between models or types. The guide is designed to provide you with fast help in choosing a suitable lubricant for your application.
STAR products can be provided with an initial supply of lubricant to ensure their smooth start-up. It is essential to ensure that these products are relubricated with a medium that is compatible with the initial lubricant.

Thermodynamics : An Engineering Approach
Book Description:
The worldwide bestseller Thermodynamics: An Engineering Approach brings further refinement to an approach that emphasizes a physical understanding of the fundamental concepts of thermodynamics. The authors offer an engineering textbook that "talks directly to tomorrow's engineers in a simple yet precise manner, that encourages creative thinking, and is read by the students with interest and enthusiasm."
The new edition features an early introduction of the first law of thermodynamics, separate coverage of closed systems energy analysis, combined coverage of control volume mass and energy analysis, and revised coverage of compressible flow. Over 300 comprehensive problems have been added to this physically intuitive text, many of which come from industrial applications.
The media package for this text is extensive, giving users a large variety of supplemental resources to choose from. A Student Resources DVD is packaged with each new copy of the text and contains the popular Engineering Equation Solver (EES) software, Physical Experiments, and an Interactive Thermodynamics tutorial. An Online Learning Center is also available to students and instructors at http://www.mhhe.com/cengel. Instructors also have access to an Instructor Resource CD-ROM that provides useful tools in order to optimize in-class presentations

This is an absolutely great book. At over 1000 pages it's a real opus - covering everything from ordinary differential equations, linear algebra, vector calculus, fourier analysis, complex analysis and probability. It's exceptionally well written - with plenty of clear examples, diagrams and exercises - constantly cross referencing back to the particular idea or formula that an example is employing. It presupposes only elementary calculus - and so makes an excellent university textbook to accompany study, or as a self-study book to further your maths knowledge.
I wish all maths books were this well written

Programmable Logic Controllers, Fourth Edition
Programmable Logic Controllers, Fourth Edition
W.Bolton, "Programmable Logic Controllers, Fourth Edition"Newnes ISBN / ASIN:0750681128 2006 304 pages PDF 2.7MB. This is the introduction to PLCs for which baffled students, technicians and managers have been waiting. In this straightforward, easy-to-read guide, Bill Bolton has kept the jargon to a minimum, considered all the programming methods in the standard IEC 1131-3 - in particular ladder programming, and presented the subject in a way that is not device specific to ensure maximum applicability to courses in electronics and control systems.Now in its fourth edition, this best-selling text has been expanded with increased coverage of industrial systems and PLCs and more consideration has been given to IEC 1131-3 and all the programming methods in the standard. The new edition brings the book fully up to date with the current developments in PLCs, describing new and important applications such as PLC use in communications (e.g. Ethernet an extremely popular system), and safety in particular proprietary emergency stop relays (now appearing in practically every PLC based system).The coverage of commonly used PLCs has been increased, including the ever popular Allen Bradley PLCs, making this book an essential source of information both for professionals wishing to update their knowledge, as well as students who require a straight forward introduction to this area of control engineering.Having read this book, readers will be able to:* Identify the main design characteristics and internal architecture of PLCs* Describe and identify the characteristics of commonly used input and output devices* Explain the processing of inputs and outputs of PLCs* Describe communication links involved with control systems* Develop ladder programs for the logic functions AND, OR, NOT, NAND, NOT and XOR* Develop functional block, instruction list, structured text and sequential function chart programs* Develop programs using internal relays, timers, counters, shift registers, sequencers and data handling* Identify safety issues with PLC systems* Identify methods used for fault diagnosis, ing and debugging programs
