Abstract: Embodiments of the present invention described herein relate to vacuum cleaners. The vacuum cleaners described herein can include a motor, a lid, a collection receptacle, and at least one support member to permit access to the interior of the vacuum cleaner. Also described herein are vacuum cleaners having a motor, a lid, a collection receptacle, and an accessory holder that can be pivotally mounted to the collection receptacle to permit access to the contents thereof.

Abstract: A housing for transporting a generally cylindrical canister configured to store at least one of a pressurized gas and a pressurized liquid. The housing includes a first housing section and a second housing section that is movable with respect to the first housing section from a first operating condition to a second operating condition. A heat transfer element is coupled to at least one of the first and the second housing sections to define at least a portion of a boundary of a generally cylindrical volume. The canister is generally fixed from movement with respect to the first and the second housing sections when the second housing section is in the first operating condition, and the canister is movable with respect to the first and the second housing sections and configured to be removed from the generally cylindrical volume when the second housing section is in the second operating condition.

Abstract: The present invention provides a header of a heat exchanger. The header can include a tank having a tank outlet, and an integral fitting including a body extending outwardly away from the tank outlet and having an outlet located remotely from the tank outlet, an inlet located between the tank outlet and the fitting outlet, and a baffle located within the body adjacent to the inlet to direct at least a portion of a fluid flow from the inlet toward the fitting outlet.

Abstract: A system and method for remote monitoring of a cathodic protection system are disclosed. In one embodiment of a system incorporating teachings of the present disclosure, a remote telemetry device may be communicatively coupled to at least one cathodic protection device operable to provide direct current to a metallic object, the telemetry device may be programmable to communicate with a central station, and the telemetry device may incorporate a transmitter and a processor. The processor may include memory and programming code to control operation of the telemetry device, and the transmitter may be operable to communicate information to a central station.

Abstract: A system comprising a remote telemetry device to monitor at least one sensor input, a central station, responsive to the remote telemetry device, a central database to store and organize information communicated by the telemetry device, and a computer network user interface that provides a user with remote access to the information stored at the central database. The telemetry device may be programmable to communicate with a central station upon at least one of an alarm condition and a regular time interval. The central station may include a central station computer server and software embedded therein to provide connection with a wide area network communications module, a database hosting module hosting a central database, and a notification module to issue alarm notification messages.

Abstract: Improper assembly and/or dissociation due to improper handling of a tank 10 to header plate 14 joint in a heat exchanger is avoided through the use of a retaining strip 50 having fingers 54 receivable in slots 36 in an upstanding flange 26 surrounding a sealing surface 28 on the header plate 14. The fingers 54 are provided with hook-like formations 60, 62, 64 which lodge behind a surface 44 of the flange 26.

Abstract: A method and improved propellant composition for eliminating secondary mue flash in small and large caliber weapons without the increased smoke production or inhibiting burning characteristics through the step of incorporating a novel microencapsulated organic coolant additive into a conventional propellant composition wherein the microencapsulated coolant will survive the propellant flame zone intact so as to decompose down barrel to cool the bases exiting the weapon barrel. The preferred organic coolant is oxamide microencapsulated within a gelatin wall material and coated with Bakelite.TM..

Abstract: A solution comprising nitrocellulose and a nitramine consisting of either X (Hexahydro-1,3,5-trinitro-s-triazine), HMX (Octahydro-1,3,5,7-tetranitro-s-tetrazine), or mixtures thereof is dissolved in a volatile, liquid acetate ester, evaporated at room temperature to form a film, and then dried. The resulting material is a homogeneous, hydrogen-bonded complex of nitrocellulose and the nitramine, useful as an energetic propellant.
