A double-tube flat microelectrophoresis cell

Journal of Colloid and Interface Science, 1967
Abstract Details are given for the construction and operation of a double-tube microelectrophoresis cell with capillaries of rectangular cross section. The theory of the cell design is discussed and experimental results are presented to compare the performance of the new cell with that of its single-tube counterpart.

Flat Cathode Ray Tubes

Journal of Vacuum Science and Technology, 1973
The hope of achieving a flat screen television display has resulted in a substantial effort by a number of individuals and companies to develop such a display. However, the performance requirements of such a display present a significant challenge to any display technique attempting to displace the extremely versatile analog defection CRT.

Flat cathode ray tubes

Physics in Technology, 1984
Recent advances in electronic displays have produced a variety of flat, thin, low voltage devices. How can the cathode ray tube compete? Slow but steady progress has been made to reduce the volume and weight of the CRT which are its main ...

Phosphor screens for flat cathode ray tubes

Philips Journal of Research, 1996
Abstract In the Zeus display panel, as in other flat-panel cathode ray tubes, the anode voltage is limited to a few kV. The effects of the anode voltage on phosphor screen performance are discussed which include energy conversion loss processes at the phosphor surface and variation of the number of luminescent centres available.

A fully electrostatic, flat, thin television tube

Proceedings of the Institution of Electrical Engineers, 1968
A description is given of important improvements and modifications which have been made in the design of a flat television tube. In the new form, magnetic components have been eliminated and considerable structural simplifications have been made. An electrostatic deflection system is described which is capable of giving deflection angles of ±60°, and a

Improved Tubing for Flat Oval Tube Condenser

SAE Technical Paper Series, 1997
<div class="htmlview paragraph">During the past few years, a new Flat Oval Tube Condenser has been developed (<span class="xref">1</span>) and launched in the market place (<span class="xref">2</span>) as a very strong and competitive alternative to the well known brazed Parallel Flow Condenser, due to its high performance

Tubes of even order and flat ?.C 2 geometries

Geometriae Dedicata, 1995
The following combinatorial-geometric problem is considered in this paper: for a given line \(L\) in \(PG(3,q)\), find a set \({\mathcal L}\) of \(q + 2\) skew lines (all skew to \(L\) too), such that the intersection of any plane through \(L\) with these \(q + 2\) lines is a hyperoval. The pair \((L, {\mathcal L})\) is called a tube.

Status on Flat Oval Tube Condenser (FOTC)

SAE Technical Paper Series, 1995
<div class="htmlview paragraph">A novel concept for automotive air conditioning condensers has been developed. The condenser utilizes flat oval tube technology currently used in automotive radiators. The innovative FOTC (Flat Oval Tube Condenser) design has mechanically expanded tubes measuring 8mm x 2.1mm with a wall thickness of 0.5mm.

Study on extrusion of aluminum microchannel flat tube

AIP Conference Proceedings, 2013
Micro-channel tube with submillimeter-diameter channels is a kind of newly developed heat transferring tube. As the micro-channel tube has many welding points and works under high pressure condition, welding strength is one of the key issues for its extrusion process. This paper presented a new study on evaluation of the seam welding strength formed in

Condensing heat transfer characteristics of aluminum flat tube

Applied Thermal Engineering, 1997
Aluminum brazed heat exchangers are used widely in automobile air conditioning systems. Usually, this kind of heat exchanger is made of a flat tube with several independent passages in the cross-section, and formed into a serpentine or a parallel flow geometry.
