Cast iron is a group of iron-carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its colour when fractured: white cast iron has carbide impurities.
History:
Cast iron was invented in China in the 5th century BC and poured into molds to make ploughshares and pots as well as weapons and pagodas. Although steel was more desirable, cast iron was cheaper and thus was more commonly used for implements in ancient China, while wrought iron or steel was used for weapons.
The cast-iron is manufactured by re-melting pig-iron with coke and limestone. This re-melting is done in a furnace known as the cupola furnace. It is more or less same as the blast furnace, but it is smaller in size. Its shape is cylindrical with diameter of about 1 m and height of about 5 m.
The working of cupola furnace is also similar to that of blast furnace. The raw materials are fed from top. The cupola furnace is worked intermittently and it is open at top. After the raw materials are placed, the furnace is fired and blast of air is forced through tuyeres. The blast of air is cold as the impurities in pig-iron are removed by the oxidation

Rubber Processing and Profiting: Compounding, Mixing, Vulcanization, Extrusio...Ajjay Kumar Gupta
Methods for processing rubber include mastication and various operations like mixing, calendering, extrusion, all processes being essential to bring crude rubber into a state suitable for shaping the final product. The former breaks down the polymer chains, and lowers their molecular mass so that viscosity is low enough for further processing. After this has been achieved, various additions can be made to the material ready for cross-linking. Rubber may be masticated on a two-roll mill or in an industrial mixer, which come in different types.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
3. Enamel
Defination:
A coloured glassy substance, translucent or opaque, fused to the
surface of articles made of metal, glass, etc, for ornament or
protection.
Examples for Enamel:
The cups are in white porcelain
with raised designs in gold and
enamel.
4. Histroy of Enamel
• The word enamel comes the High
German word “smelzan” later
becoming “esmail” in Old French.
Hence the current usage of
“smalto” in Italian, “email” in
French and German and “enamel”
in English.
• In history, enamels were initially
applied on firstly gold, then silver,
copper, bronze and more latterly
on iron and steel.
• The earliest known pieces of
enamel can be found in the
Nicosia museum in Cyprus and
Mycenae.
6. The manufacture of enamel
The various stages in manufacturing
enamel:
1.The fusion stage.
2.Another stage(Alternative fusion
process)
7. The fusion stage
• The first step is to
check, weigh and mix
the various
constituents of
enamel.
• The “glass” to be
melted at a
temperature of
between 1100°C and
1300°C.
• The most common
process involves using
a tunnel furnace where
the mixture is
introduced at one end
and comes out the
other.
• The mixture remains in
the furnace about an
hour.
• When it emerges it is
cooled rapidly through
a water cooled rolling
mill to form a glass
sheet.
8. Another stage(Alternative fusion process)
• An alternative fusion process involves using a rotary furnace into which
the constituents are poured, mixed and heated.
• After cooling and crushing, enamel frit is obtained.
• Enamel frit may be applied in liquid form or may also form of powder.
• In case of liquid form,the addition of certain ingredients (suspension,
refractory,colouring agents, electrolytes and opacifiers), the frit is ground
and mixed with water to form a slurry.
• When power form is used,the enamel powder obtained does not require
any additives or further treatment at the enameller and can be directly
used in powder spray guns.
