Glow Lamp Manual

General Electric Glow Lamp Manual

General Electric Glow Lamp Manual, Theory-Circuits-Ratings, 2nd Ed., 1966.  This circa 1966 reference manual outlines GE's line of glow lamps or neon tubes including those designed for computer logic, switching, lighting, and indicator lamps.  This work includes numerous application examples, reference implementation schematics and provides technical details for many models of the GE lineup for this category.

Little Giant Transistor

 Littlest Giant Transistors Mighty Mites

The Littlest Giant: Transistors... Mighty Mites of Electronics! - Well transistors are solid devices, Unlike vacuum tubes. A remarkable Metal called germanium does the job. The transistor amplifies current by Adding electrons as electricity flows Through its germanium crystal. There Are no filaments to burn out, no 
Glass to break.

Surge Protection and Lightning Arrestors

Load Surge Protection

Supplementary to EMI/RFI/EMC Immunity of an Equipment. Many Installations are subject to Highly Disruptive Electrical Environment not just EMI. Depending on the budget and the situation a solution has to be found. Sometimes a CVT or an Isolation Transformer can do a lot of good. 

Converting all Energy inputs to battery energy and having a Isolated Synthetic Sine Supply may be an expensive but good solution. Either way the devices that face the harsh environment have to be over rated along with these protections.

Quadzilla 4 in 1 Chip

Quadzilla strikes again

This is a booklet published by National Semiconductor that lists many applications for their various "quad" - 4 circuits in one chip - devices.

Voltage Controlled Oscillators, up-down staircase generator, time delays, limit comparators, and so on, all made with quads containing amplifiers or comparators. Here is a new concept of not only using the advantages shown for the digital world, but the ability to use simple quad linear devices to build more complex circuits.

Quad Differential Comparator LM339

Quad Comparator LM339

These devices consist of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible, as long as the difference between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage.
