The Machine Shop

The facility includes a machine shop capable of diversified work and adequate equipment for model work plus production of certain components. For example, a machine for cutting the core of the toroidal potentiometer, as well as a winding machine for the long mandrel required by same device, have been designed by the mechanical engineering department and fabricated by the machine shop. Also, several components of the electromechanical integration computer, such as gear trains, coders and decoders, and other newly designed servo components are successfully fabricated by the machine shop.

The machine shop is also adapted to fabricate microwave components and antenna feeds. It also mass produces several components, now employed in lighting installations, such as motorized autotransformer dimmers, brackets, chassis and cabinet and sheet metal work for the electronic equipment. The machine shop now includes the following equipment:

Engineering Talent

The engineering staff of ADI consists mainly of the scientists who originally conceived, organized, and formulated the company and its goals. As part owners, these scientists contribute maximum effort towards its success. The group consists of Electrical and Mechanical Engineers, Physicists and Chemists, with long and broad experience. The following are some of the many fields of capability of the ADI engineering staff for research development and production:

The Cold Cathode Interference Free Fluorescent Lamp

This type of fluorescent lamp presents the following advantages versus the conventional hot cathode fluorescent lamp.

1 It is instant starting-therefore, it does not require separate starter.
2 It is long-lived. Its average life is about 27,000 hours. Further, its
life length is not deteriorated by on-and-off switching. Conven-
tional fluorescent lamps lose as much as 25 hours from their life
with every switching.

3 The Cold Cathode fluorescent lamp can be dimmed like an ordi-
nary incandescent lamp.

4 The Cold Cathode's fluorescent lamps generate minimum radio
interference. It is therefore the only solution to quiet illumination, so
Important in any installation where electronic equipment may re-
ceive interference from fluorescent lighting. For this reason, Cold
Cathode supplies fluorescent lighting in most military noise-sensi-
tive installations.

5 Cold Cathode lamps do not require heating element at the cathode;
therefore, operate at lower temperature than conventional
fluorescents.

6 Cold Cathode lamps provide an improved electrode design with
greater contact area; therefore, they offer lower contact resistance
losses, and they are rugged enough to withstand greater vibration
and shock.

Saturable Reactor Controlled Constant Current Supplies

ADI is now going into production of constant current supplies controlled by a saturable reactor. These supplies hold the output current constant to within plus or minus 10% for any load from a short circuit to 2000 ohms, and variations in the input line voltage by as much as 100%.

New Advancement Devices Under Development

The Advancement Devices Engineers are feverishly working to place into the market a new line of diversified components and systems which are expected to revolutionize several aspects of present day technology. Some of these developments are:

THE TOROIDAL POTENTIOMETER This high accuracy component combines the long mandrel and multi-turn advantage of the heli-pot with the continuity offered by the circular single tura potentiometers. As many as 32 turns and 100 inch of resisting element are provided within a 5" diameter potentiometer. The multi-turn feature helps to practically eliminate any backlash errors. A gear is provided for direct mechanical output.

THE INTEGRAL CALCULUS COMPUTER The unit will be able to integrate the product of any number of any functions over any definite interval. The integral will be given as a number. The project is now in the breadboard stage.

HIGH SPEED CLUTCH AND BRAKE This new clutch concept permits engagement of two shafts at any speeds, without the fear of breakage. It engages and disengages very smoothly, thus avoiding sudden jolts. Since the clutch does not depend on friction, it suffers negligible wear. Project at model stage.

HIGH SPEED SELECTOR SWITCH A low inertia concept of a mechanical selector switch permits the scanning of up to 400 circuits per second. The selector switch has the capability of stopping precisely at the activated circuit. Breadboard stage.

BATTERY CHARGER A low cost automatic battery charger controls the charging rate around a fixed current value, and shuts automatically when the battery reaches optimum charge. Breadboard stage.

A NARROW BAND TELEVISION SYSTEM Satisfactory television picture is expected from extremely narrow bandwidths. Project in breadboard stage.

FUEL BATTERY SYSTEM Chemicals are fed in fluid form and processed by the battery as current is needed. In design stage.

AIRCRAFT ANTI-COLLISION SYSTEM A novel design for an aircraft anti-collision system includes special antenna design for elimination of ground reflection: a computer for the determination of relative target height, target range, rate of closure, time to closest approach, distance to closest approach, and probability of collision, plus special three-dimensional target display, with associated warning devices. In design stage.

INFRARED TELEMETER A device for determining distance of I.R. or luminous objects. Design stage.

INFORMATION CORRELATOR The purpose of this device is to examine and determine the similarities and differences between two coded situations.

ANTENNA FEEDS Advancement Devices are now developing a new design of bipolarized antenna feed with extremely low VSWR. In the future, several microwave components incorporating new concepts will enter the company's products.
