Design and Analysis of Internal Hinge Check Valve

The advent of computers and the tremendous strides they have made in the recent times have brought the capability to model complex design and solve innumerable number of mathematical equations in a flash of time, to the desktop of the design engineer. CREO is windows based software package, which enables the design and Ansys will analyse the mechanical and other system. This project is to design 16” Class 300 Internal Hinge Swing Check Valve with compliance to BS 1868 standard. The internal hinge check valve design is to overcome the leakage issue in external hinge design. The aim is to design a check valve without puncturing the body and to assemble the whole disc sub-assembly inside the body. The design of internal hinge check valves is carried out with the help of CREO design software and subsequently analysis is done with the help of ANSYS software package

Automated Capping of Liquid Storage Bottles in Food Industry

The high speed automated production systems are employed nowadays to achieve improved quality of manufacturing accuracy with improvised and high production rates. This paper introduces a new design for the chucks which are used for capping the liquid bottles for food and beverage industry. This new chuck is designed for multi-functional purposes which reduce the time for changing the chuck if caps of different diameters are used. The power transmission to the chucks is delivered by using “Hysteresis magnetic type clutches”, for controlling and achieving smooth constant torque. The specialty of these clutches is that it offers smooth disengagement without jerks and bumps that increase its wear life compared to other ordinary clutches. The deformation and stress in the component are studied by performing the computer-aided structural analysis. With the analysis maximum deformation and maximum stress can be found out and the factor of safety can be calculated

Propose & Design an Automated Mechanical System for Capping and Water Level Measurement of Water Bottle

The purpose of this poster is to develop an automated production layout along with its design for above mentioned subject. The research work includes designing the fixture for holding the bottle while capping and three-finger self-centering gripper for placing and moving the bottle to and fro from guideways to the bottle bottom holder and vice versa. Suggesting an automated system and technology for checking the water level in bottle and effectively removing such bottles from assembly line would also be one of the objectives of this poster. Tools like automated torque wrench, precision indexing conveyor belts, three-finger self-centering grippers, three-jaw chuck (bottle holding fixture), infrared level detection sensors have been used in this system. FEA analysis of three-finger gripper and three-jaw chuck is done to verify their design. The components of this system are designed using Creo Parametric 2.0. Designed components are analyzed using ANSYS Workbench 16.0

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
