The industrial model name

 Allen Wrench Kit of Inner and Outer Hexagon Head, All in One

The industrial model details

The industrial model consists of many Allen Wrench, of inner or outer hexagon, and more than one measurement at the same time, with one hand to open and close the Allen Screw or the usual screw. All sizes are available in one bag. Since the kit is only one arm, there will be a reduction in the amount of metal used and hence the price, weight and size of the bag. A binary or triple combination can be used to obtain a certain number to reduce the number of pieces in the set, thus obtaining the largest number of key numbers (from the smallest number to the largest number). The yellow pieces (of bronze) in the base of the bag can form to get the key (internal) or (external). The dark pieces of the industrial model in the lid of the bag on the left are used to magnify the Allen Wrench from a size to a larger one if the piece is inserted into the base or arm-shaped. Either on the right-hand side is used to scale from size to smaller size. Finally, the two pieces in the lid of the bag in the center (of zinc) are used to reduce (from the top of the piece) or to enlarge (from the bottom of the piece) in case of inserting the piece in the base Allen Wrench or in any other suitable piece to obtain the specific number for the Allen Wrench, all of this is from the outside, where it can be used from the inside, as a  circular Wrench and not nick because the pieces are hollow (Shell) and is designed to relax and screw the screws either from the small or large side, which may require the introduction of a piece of bronze between them and the arm or the use of two pieces of zinc or more according to the desired key number .

Publishing a book

The new book has been published

Selected topics in mechanical engineering

In the German publishing house Lambert, the book was written by a group of teachers from the Department of Mechanical Engineering at the University of Technology. The group included:

· Prof. Jafar Mahdi Hassan

· Dr.Lith Jaafar Habib

Nizar Yasser Jassim

Selected topics in mechanical engineering is an important and necessary issue in various engineering fields. All engineers and professionals need the basic knowledge about this subject to improve their skills and practice on how to establish their own test rigs in terms of design and material requirement (Fluid Flow and Heat Transfer), process and control tooling, manufacturing, measuring instruments, equipment, and the use of sophisticated and skillful computer software programs.

        Therefore, this book is mainly devoted to help graduate students who are not familiar with the designing and constructing test rig to conduct their experimental projects, especially for the ‘Fluid Flow and Heat Transfer’ projects. It is also useful for postgraduate students during their higher studies to develop their ability to design and build the test rig for the MSc and PhD work. Moreover, it is beneficial for working engineers in the Research and Development Centers to enhance their scientific capability and gives them the proper procedure to design and construct the relevant test rigs.

              Thus, all chapters of this book are presented in the simplest Arabic style, and great efforts are made to compose the book free from error. However, comments are welcomed to improve the book, which can be sent to the authors. All the list of references at the end of the book chapter's is available electronically and as hard copies in the library of the Mechanical Engineering Department – University of Technology.

      Finally, we would like to express our sincere appreciation to all efforts and endeavors presented by the department facilities to prepare this book and we hope it is advantageous and will result in beneficial outcomes.
