Developing and Easing the Brazing Method

Brazing generally require cumbersome apparatus be it induction, vacuum or torch brazing. In torch brazing, metals are joined by using the oxyacetylene cylinder. It thus becomes difficult to carry out brazing at the places where it is not possible to take heavy gas cylinders and brazing apparatuses. So it is tried to figure out the method to carry out brazing at places where conventional brazing...

Experimental Investigation of the Rolling Piston Type Refrigerating Rotary Compressor with R502

General Method for Screw Compressor Profile Generation

The paper presents a general algorithm for the specification of a screw machine geometry. The conjugancy condition was solved numerically which thereby enables a variety of primary arc curves to be introduced. In addition, an optional numerical derivation of primary arcs enables any analytical function and even discrete point functions to be used for the primary arc. The approach also simplifie...

Simple method for auto-ophthalmoscopy.

Auto-ophthalmoscopy, the process by which one's own fundus can be viewed, is an old technique which has been subject to many slight refinements throughout the years. Purkinje described 3 methods by which an impression of the vascular system could be obtained as far back as the 1820s (see von Helmholtz'). The reason why ordinarily we do not perceive the outline of our eyes' vascular system is be...
