Noraluca Coal, a naturally occurring combustible solid, is one of the world's most important and abundant energy sources. From its introduction 4, years ago as a fuel for heating and cooking, to its nineteenth- and twentieth-century use in generating electricity and as a chemical feedstockcoal, along with oil and natural gas, has remained an important source of energy. The United States alone has 1.
A suitable last is placed inside the shoe, which is then placed on a straight edge acting as a fulcrum for applying load on the joint of the sole and upper. The maximum load the sole can withstand before coming off is determined and reported as the sole adhesion strength. This test can be carried out either at the heel or at the toe of the shoe.
The PROLIFIC Sole Adhesion Tester consists of a cantilever type load cell with a digital readout to measure and indicate the force applied at the junction of the sole or heel and the upper and a set of interchangeable toe pieces having different curvatures.
The load cell measures the force applied on the joint, which is indicated directly in kilograms on a digital readout with a peak force memory to indicate the maximum force applied before the failure of adhesion.
Five toe pieces of different curvatures are provided to enable toes and heels of different shapes and sizes to be tested. The length of arc of each toe piece, however, is the same to ensure that the force is applied only on a fixed length of joint.
These are made from carbon steel for giving a long operational life. Any one of the toe pieces can be held in the equipment at one time.
The fulcrum on which the shoe is placed during the test has adjustable height to enable soles of different thickness to be tested. The height of the fulcrum is adjusted with the help of six spacer strips provided with the equipment.
This tester provides useful information about the resistance of compounds of vulcanized rubber to flex cracking when subjected to flexing. Cracks develop in that part of the surface where stresses are set up during flexing, or if that part of the surface initially contains a crack, cause this crack to extend in a direction perpendicular to the stress.
The De Mattia Flex Tester consists of a set of grips to hold test specimens in two tiers with their holding faces lying in the same vertical plane. The flexing and un-flexing action is provided by holding one end of the test specimens in a fixed grip and the other end in a reciprocating grip.
The set of grips has two fixed grips and one large reciprocating grip positioned between them in order to flex half of the test specimens while the other half are being un-flexed. The reciprocating grip is fitted with gunmetal bushes, which slide on hardened and ground rods made of high carbon steel.
The reciprocating motion is provided by an eccentric and linkage mechanism driven by an electric motor through a V-belt and pulleys. A six digit electronic counter with reset and memory backup is provided for indicating the number of test cycles undergone.
The standard model of the tester is designed to test up to six test specimens at one time. A special model capable of testing up to twelve test specimens at a time can also be offered against specific enquiries.
Moulding dies for preparing test specimen and jig and punch assembly for making initial crack in test specimens for crack growth test are available as optional accessories.
A special model of the tester, which can test up to twelve rubber specimens at elevated temperature, is also available.
In this model the grips of the tester are placed inside a double walled oven having a front door fitted with toughened glass.
The inner walls of the oven are made of aluminium sheet while the outer ones are of mild steel sheet. The space between the walls is filled with mineral wool for insulation.
An electric heating element is provided for heating the air in the oven. An air-circulating fan for uniform temperature distribution in the oven is also provided.
The temperature of the oven is controlled and indicated by a digital temperature controller cum indicator.Montel manufactures and supplies moisture meters, damp meters, moisture detectors, and dampness measurement equipment to the timber, lumber, woodworking, building, boating and marine markets, for the detection and measurement of water and moisture in wood, plaster, concrete, GRP (Glass-reinforced plastic), fibreglass etc.
