Filed:

Jun 1, 2001

Appl. No.:

09/870523

Inventors:

Robert Peter Koenig - Westminster CO 80234

International Classification:

F28F 2702

US Classification:

165 96, 165 50, 165101, 165103, 165 481, 237 70, 237 71

Abstract:

A coil modulator apparatus for use in connection with heat transfer coil assemblies found in commercial heating and air conditioning units is used to divert passage of water flow in certain sections of each tube in the coil assembly. The coil modulator apparatus comprises an inner valve, having valve ports in the sides of the valve, that rotates within an outer housing. Apertures in the outer housing connect with each tube in the bank of tubes so that there is an aperture in the outer housing that connects with both the downstream tube section and the upstream tube section of each tube. A portion of the water that collects in the modulator then flows back out of the modulator and into each of the downstream sections of every tube in the coil assembly. Another portion of the water in the modulator is diverted from the bank of tubes so that it flows out of the bypass tube of the modulator and directly back to the return feed of the coil assembly unit.

Abstract:

A coil modulator apparatus for use in connection with heat transfer coil assemblies found in commercial heating and air conditioning units is used to limit the number of active tube sections in cooling coil assemblies. The two port modulator apparatus comprises an inner valve, having valve ports in the sides of the valve, that rotates within an outer housing having openings that correspond to those ports in the inner valve. Apertures in the outer housing connect with upstream and downstream tube sections in the bank of tubes. As the actuator arm of the coil assembly is rotated this rotates one of the valves changing the orientation of the outer and inner valve ports and so cutting off water flow in various tubes depending upon how far the actuator is moved.

Assignee:

Datex Ohmeda, Inc. - Madison WI

International Classification:

H01G 9/00

US Classification:

29842, 29825, 29837, 29845, 29854

Abstract:

The present invention is directed to a socket connector to couple electrical plugs to sockets mounted on circuit boards or cable ends. The socket connector includes a socket that receives an electrical plug and a socket silo. The silo may contain a beveled outer surface that receives a beveled face on the plug. The plug is held in the socket by latches disposed on the plug. The latches include pawls that fit within pawl receiving chambers in the socket and couple the plug to the socket. The latch and hinged section may rotate into a recessed section on the plug from an extended to a retracted position. A locking portion on the pawl and the receiving chamber may be angled to develop a desired pullout force.
