Substitution of old germanium transistors in radio

Jul 13, 2013 The original transistor would be a PNP germanium type (AEI TR1A). I think an RF type, or at least designated that I believe (by Tri-ang). Original battery voltage was 9V. If you were to substitute that germanium PNP transistor with a modern PNP silicon transistor, what transistor would you...

Replacing Germanium Transistors Antique Radios

Additionally, Germanium transistors usually didn't have as much gain as was needed/wanted, leading to circuit design decisions that would be considered really bad today. Germanium circuits are often overly sensitive to Hfe/beta by modern standards. If you are going to mess around with Germanium, build a test fixture like this one.

Hammer Mill: components, operating principles, types, uses

Jan 11, 2016 Hammer Mill. Hammer mill is the most widely used grinding mill and among the oldest. Hammer mills consist of a series of hammers (usually four or more) hinged on a central shaft and enclosed within a rigid metal case. It produces size reduction by impact. The materials to be milled are struck by these rectangular pieces of hardened steel

A combined tool with stacked blades was developed to efficiently fabricate microchannel plates by using the multi-blade milling process. The microchannel plates with 0.632 mm in hydraulic diameter and 40 mm in length were then used to assemble the microchannel heat exchanger. The thermal performance of microchannel heat exchanger was experimentally investigated with different flow rates.
