Hydraulic Jack is a device that uses force to lift heavy loads. The primary
mechanism with which force is applied varies, depending on the specific type of
jack, but is typically a screw thread or a hydraulic cylinder. Jacks can be
categorized based on the type of force they employ: mechanical or hydraulic.
Mechanical jacks, such as car jacks and house jacks, lift heavy equipment and are
rated based on lifting capacity (for example, the number of tons they can lift).
Hydraulic jacks tend to be stronger and can lift heavier loads higher, and include
bottle jacks and floor jacks.
Consists of the basic concepts of a Hydraulic System used in industries along with the working of its elements used with well-labeled diagrams and also it has information about the Hydraulic Power Pack and its circuit diagram.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Typical Units of Pressure
The SI unit for pressure is the Pascal (Pa), equal to one newton per
square meter (N/m2 or kg·m−1·s−2).
1 Bar = 14.69 psi = 100 kilo pascal
17. www.nfiautomation.org
Example: Motor Reversing System
b. Motor-Reversing System. A power-driven pump operating a reversible rotary motor. A
reversing valve directs fluid to either side of the motor and back to the reservoir. A relief valve
protects the system against excess pressure and can bypass pump output to the reservoir, if
pressure rises too high.
21. www.nfiautomation.org
Hydraulic Pumps
Hydraulic pumps convert mechanical energy from a prime mover (engine or electric
motor) into hydraulic (pressure) energy. The pressure energy is used then to operate an
actuator. Pumps push on a hydraulic fluid and create flow.

Hydraulic Actuation System
Actuators – Hydraulic Cylinders
Used to produce linear motion
Double Acting Double Rod Cylinder
Double-Acting Double-Rod Cylinder
A double ended piston rod makes a cylinder stronger against side
load, as it has two bearings at the widest distance possible. This type
of cylinder is often mounted with rods fixed and the cylinder itself
moving to displace a part.
44. www.nfiautomation.org
Piston Force
Dependent on the air pressure, the cylinder diameter, and the frictional
resistance of the sealing components.

Hydraulic Actuation System
Pres sure Re lief Valve
Pressure Relief Valve
Simple, direct-acting relief valve has no
adjusting screw and therefore opens at
a fixed, pre-set pressure as controlled
by setting of compression spring.
Adjustable, direct-acting relief valve blocks
flow through the valve until force of system
pressure on the poppet overcomes the
adjustable spring force and downstream
pressure.

lines
