Filed:

Oct 16, 2001

Appl. No.:

09/981974

Inventors:

Daniel McCleary - Riverview FL 33569
Mark Gaffin - Valrico FL 33594

International Classification:

B08B 904

US Classification:

134167, 134169 C

Abstract:

An air or liquid handling device access and cleaning method and apparatus which allows the cleaning operator to clean the interior of the air or liquid handling device while the device is operational, thus negating the conventional need to shut down the system. The apparatus contains a flexible cleaning hose which delivers a cleaning agent through a nozzle connected to the distal end of the hose. The hose is subsequently inserting into a hose sealing mechanism which ensures and air-tight seal around the periphery of the hose while still allowing rotational and longitudinal movement of the hose. The preferred embodiment also connects, in seriatim, a pipe âTâ junction with a pressure relief valve, a pipe bell reducer, a pipe extension and an access control valve, thus permitting controlled access to the pressurized interior of the air or liquid handling device.

Abstract:

An industrial air or liquid handling device access and cleaning apparatus which allows the cleaning operator to clean the interior of a device while the device continues in operation, thus negating the need to shut down the system. The apparatus incorporates a cleaning nozzle attached to a cleaning agent delivery tube or hose which projects into the interior of the device through a sealing mechanism which ensures an air-tight seal around the periphery of the tube while still allowing rotational and longitudinal movement of the tube. The preferred embodiment connects, in seriatim, a pipe “T” junction with a pressure relief valve, a pipe bell reducer, a pipe extension, and an access control valve. Inside the device, the tube and nozzle are carried by a rotatably mounted slotted tracking tube for directing the cleaning nozzle through a predefined range of both axial and angular movement.

Abstract:

The present invention is directed to method, and associated system, for communicating pre-connect information between a calling endpoint and a called endpoint in an Integrated Services Digital Network (ISDN) system. In accordance with one aspect of the present invention, the method includes the steps of dialing the called endpoint from the calling endpoint, and setting a calling party's subaddress information element to a value that allows the contents of a subaddress information field to be user specified. The method further includes the steps of specifying the contents of the subaddress information field, and transmitting the message of information to the called endpoint, the message of information including the calling party's subaddress information element. In accordance with the preferred embodiment of the invention, the system is a digital communication system that is compatible with the Open Systems Interconnection (OSI) seven layer model in communication at the network layer of the OSI model is defined by ITU-T Q. 931 specification.
