US Patent:

7073344, Jul 11, 2006

Filed:

Jul 9, 2004

Appl. No.:

10/888561

Inventors:

Ran Luo - New Albany MS, US
Kenneth W. Owen - New Albany MS, US

Assignee:

Standex International Corporation - Salem NH

International Classification:

F25D 21/00

US Classification:

62234

Abstract:

A cooling system that has an electrical controller that controls an electric expansion valve and the defrost cycle using a reversing valve. The need for heater circuit to achieve defrost is eliminated. The system permits the defrosting the evaporator system in less time required for conventional defrost methods. The cooling system also eliminates the need for a head pressure control valve and check valves. Due to the less wiring and lower operating costs, the invention provides significant cost savings.

Inventors:

Ran Luo - New Albany MS, US
Kenneth W. Owen - New Albany MS, US

International Classification:

F25B 41/04

US Classification:

62222

Abstract:

An extra low temperature refrigeration system consisting of a two-stage compressor that has an electronic controller. The electronic controller controls an electric expansion valve in the evaporator, which modulates the true superheat. There is also an electric pressure control valve in the condenser, which modulates the head pressure in cool mode, and the suction pressure in defrost mode. The defrost cycle uses a reversing valve. The liquid refrigerant for the inter-stage sub-cooling circuit is constantly provided by a sub-condenser separated from a conventional one condenser system. Therefore, the system provides constant cooling for the compressor motor windings as the compressor runs. There is a one-way pathway from the main condenser circuit to the sub-condenser circuit. This pathway will call for more refrigerant from the main circuit to the sub-cooling circuit as demanded. The inter-stage sub-cooling circuit uses an electric expansion valve true superheat control for its sub-cooler.

F41H 5/24

US Classification:

89 3602, 109 1 S

Abstract:

A ballistic panel composed of multiple layers. An outer layer is preferably metal. An inner layer is provided that can serve as decorative, if desired. Adhered to the outer layer is a layer of ballistic material, preferably KEVLAR or other synthetic ballistic fiber. Foamed in place is a layer of foam, preferably urethane. Also, featured is a plurality of cam locks with each cam lock having a male and a corresponding female part such that the adjacent panels can be easily and quickly locked together to form a safe enclosure.
