Abstract: A method of protecting the end fittings of a tube or hose includes the steps of providing an end fitting that is attached to a hose or tube. Providing a heat shrinkable plastic capsule having a tubular portion with an open end and a closed end. Placing the plastic capsule over the end fitting until the closed end of the capsule is in contact with end of the fitting. Placing a magnet at the outer face of the capsule to maintain the end of the capsule in contact with the end of the fitting and heat shrinking the capsule onto the fitting. Removing the magnet from the end of the capsuled fitting.

Abstract: An exiting cleaning projectile verification system for a tube cleaning system includes a tube cleaning system having a control system for controlling the cleaning system, a projectile launcher, a projectile, a tube, and a containment system, the cleaning projectile being launched through the tube and cleaning the interior of the tube, the projectile exiting the tube and entering the containment system and a sensor that detects the projectile exiting the tube. The sensor is in communication with the containment system. The sensor may include an electric eye that detects the presence of the projectile entering the containment system. The sensor may also include a feedback line connected to the control system that automatically shuts off the control system when a problem is detected. The sensor may also emit an audible signal. One or more counters count the number of projectiles launched and the number entering the containment system. A difference in the count is an indication of a problem.

Abstract: A method and structure for constructing a waterproof concrete structure using a central core of rigid foam attached to exterior castings, cemented together and anchored to a foundation.

Abstract: In a telecommunications system (100), a method and apparatus for priority queuing of callers requesting an opportunity to speak during a push-to-talk call is disclosed. The method includes defining a group for a call in response to a user input (210, 410), assigning a priority level designation to the at least one participant (220, 420), and granting access to transmit speech in a push-to-talk call based on the priority level (270, 280, 290, 300). The apparatus includes a first server (150) and a second server (140) communicatively coupled to the first server. The second server is programmed to implement the steps given above.

Abstract: In a telecommunications system (100), a method and apparatus for buffering the initial speech of an initial speaker in a push-to-talk call is disclosed. The method includes the steps of determining at least one participant or group to call (410, 510), sending a call request to the at least one participant or group (520), determining if the at least one participant or group is registered with the telecommunications system, notifying the initial speaker to begin speaking after determining at least one participant is registered with the telecommunications system but prior to connecting all called parties, receiving and digitizing voice packets from the initial speaker, storing the digitized data packets in a storage medium and transmitting the digitized voice packets when a predetermined packet transmission triggering event occurs.

Abstract: A system for cleaning the barrel of a gun which includes a compressible foam projectile, a source of compressed gas, and a flexible connector, such as a hose, for connecting the projectile with the cylinder is disclosed. The projectile resides within a nozzle which is secured to the hose. The cylinder is secured to one end of the hose. In order to clean the gun, the nozzle with the projectile inserted therein is placed within the barrel of the gun. The nozzle forms an airtight seal with the barrel. The compressed gas is released from the cylinder into the nozzle. The gas propels the projectile out of the nozzle and through the barrel. As the projectile travels through the barrel, it wipes the barrel clean.
