Sir Joseph Whitworth invented the Whitworth quick return mechanism in the 19th century to convert rotational motion into reciprocating linear motion. The mechanism uses four links - a fixed link, slotted bar, driving crank, and slider - to transform the rotation of a crank into the back-and-forth motion of a cutting tool. As the crank rotates clockwise and counterclockwise, the connected slider moves the tool across its stroke to shape or cut materials. This innovative mechanism is still used today in machine tools like shaper and slotter machines.

5171 2015 YRen The synthesis of monolayer MoS2Yi Ren
1) Monolayer MoS2 has potential advantages as a channel material for thin film transistors due to its atomic thickness, bandgap, and lack of dangling bonds.
2) There are two main approaches to synthesizing monolayer MoS2 - exfoliation and bottom-up growth. Exfoliation can produce high quality samples but not at large scale, while bottom-up methods like CVD allow for better control over layer number and uniformity.
3) Recent progress has been made in bottom-up synthesis techniques using sulfurization of molybdenum precursors, thermal decomposition of thiosalts, and atomic layer deposition to produce wafer-scale monolayer MoS2 films with promising
Journal club- Enteral Paracetamol or IV Indomethacin for closure of PDAZaheen Zehra
This randomized controlled trial compared the efficacy of enteral paracetamol and intravenous indomethacin for closing a patent ductus arteriosus (PDA) in preterm neonates. 77 preterm infants were randomly assigned to receive either paracetamol drops through a feeding tube every 6 hours for 7 days, or intravenous indomethacin once daily for 3 days. The primary outcome was PDA closure rate assessed by echocardiography. There was no significant difference in PDA closure rates or secondary outcomes like renal impairment between the two groups. The study concluded that oral paracetamol is safe but not superior to intravenous indomethacin for closing a PDA in preterm neonates

Controller design for gantry crane system using modified sine cosine optimiza...TELKOMNIKA JOURNAL
The objective of this research paper is to design a control system to optimize the operating works of the gantry crane system. The dynamic model of the gantry crane system is derived in terms of trolley position and payload oscillation, which is highly nonlinear. The crane system should have the capability to transfer the material to destination end with desired speed along with reducing the load oscillation, obtain expected trolley position and preserving the safety. Proposed controlling method is based on the proportional-integral-derivative (PID) controller with a series differential compensator to control the swinging of the payload and the system trolley movement in order to perform the optimum utilization of the gantry crane. Standard sine cosine optimization algorithm is one of the most-recent optimization techniques based on a stochastic algorithm was presented to tune the PID controller with a series differential compensator. Furthermore, the considered optimization algorithm is modified in order to overcome the inherent drawbacks and solve complex benchmark test functions and to find the optimal design's parameters of the proposed controller. The simulation results show that the modified sine cosine optimization algorithm has better global search performance and exhibits good computational robustness based on test functions. Moreover, the results of testing the gantry crane model reveal that the proposed controller with standard and modified algorithms is effective, feasible and robust in achieving the desired requirements.

Structural analysis of a road bridge using ansysSubham kumar
This document describes a structural analysis of a road bridge using finite element modeling. It provides background on bridges and their types. The analysis procedure involves creating a 3D model of the bridge in ANSYS, defining the material properties of steel and concrete, meshing the model into finite elements, and applying boundary conditions to model how the bridge is supported. The results will provide insights into the stresses and performance of the bridge structure.

Design, analysis and development of special purpose machine to carry heavy lo...eSAT Journals
Abstract
In the olden days very complicated thing is in the industry is to carry heavy loaded components and lifting from one place to another place, human effort needs lots of energy and it takes more time for same work, there are many huge and large amount of load lifting machine available, in that first started with gantry hoist and gantry cranes with which they carry heavy loads from one place to other, it works so far by the time but it can operate only in open place, in small scale industries it can’t work, during the period the need is new machine which works in small scale industries with good time, the changing the generation with the new technology industries are planned to develop the special purpose machine which is used to lift the heavy loads. Structural analysis of the “Gantry Structure” has been carried out to find the mechanical response of the structure, subjected to applied loads and boundary conditions. The results include deformed shape of the structure, displacements at required locations. Modal analysis done for checking the model, Gravity Loading Applied for different position and checked for the deformation of Solid Beam for different position. Optimization is done to reduce the cost of the structure. The response of the structure got by structural analysis using MSC Nastran.

Perumin El Brocal Overland Conveyor - Control System Redesign and ImplementationEduardo Pinto
Demand from the Mining industry requires conveyors to efficiently and reliably transport bulk material long distances across difficult terrain at high throughputs. These conveyors are technically complex requiring multiple drive units and a robust control philosophy to control motor torque and tension distribution throughout the conveyor.
The successful implementation of the conveyor depends upon the seamless integration of the mechanical design and the control system to ensure safe and reliable performance under all operating conditions.
This case study examines the control system re-design and network modifications implemented by Conveyor Dynamics Inc. on the original El Brocal Overland Conveyor system to resolve problems associated with the conveyor drive torque control during starting, stopping and running conditions. These problems resulted in symptoms including erratic conveyor behavior, belt over tension, drive slip and inability to achieve nameplate capacity.
This paper details the problems found and provides an outline of the correct control philosophy that should be applied to multiple drive conveyors. The author then demonstrates the correct behavior of drives using this control philosophy by examining the results following successful implementation.

Similar to ME3310 - Project 1 - Linkage Design for a Cookie Flipper (20)
7. Goal Statement
Design a means to flip peanut brittle 180 degrees such that previously downward facing side is
now facing up.
Task Specifications
● Motion of spatula will be achieved via linkage mechanism
● Input should be a motor rotating a single link.
● Full joints are prefered to half joints
● A spatula which can efficiently load peanut brittle (PB) has been designed and given to
us
● PB is 9” square
● PB must be flipped 180 degrees
● PB should not be placed on top of other pieces of PB
● PB should not be broken while being flipped
● PB should be centered on conveyor after flipping
● No damage or alterations should be done to the conveyor
● Spatula should remain stationary or in forward level motion to allow at least half of the
PB to be loaded onto the spatula
● Linkages must be strong enough to hold PB
● Linkages and joints must be strong enough to rotate at high speeds.over 3 rad/s
● PB loading time should be 0.5 seconds minimum, 0.75 seconds max
● Linkage “cycle” must keep up with the rate at which PB approaches the flipper, which
would give a mechanism 1.25 seconds to complete a flip cycle before a new PB must be
loaded
● PB must maintain a separation of 6 in between each piece both before and after flipping
● All designs and PB handling must be OSHA and FDA compliant
