摘要:
A method of cooling a PVC dry blend powder in a vessel by spraying a liquified inert gas into the vessel such that the liquified inert gas contacts the powder. The PVC dry blend powder is made by mixing a powdered PVC resin with ingredients selected from the group consisting of plasticizers, stabilizers, and pigments in a mixing vessel by using a heating and mixing cycle followed by a liquified inert gas cooling cycle. The flow properties of PVC dry blend powder made by this method have an improved shelf life.

A preventive device involves an elastic band capable of being secured about the base of a mattress or box spring. The elastic band is impregnated or coated with a composition that repels bed bugs. The elastic band also protects bedding from the infestation of bedbugs, which is much easier than eradication.

A chlorinator system for pools or spas is disclosed. The chlorinator system includes a replaceable chlorinator cell cartridge having built in sensors, switches, and custom connections. The chlorinator system includes a controller, a chlorinator, a replaceable cell cartridge, and compression fittings for connecting the chlorinator to piping of a pool or spa system. The cartridge includes a body, a bi-directional flow switch, a connector plug, a lid, a printed circuit board, which includes non-volatile memory, and electrically-charged plates or blades.

An underwater light having a sealed polymer housing and a method of manufacture are provided. The light includes a rear housing component formed at least in part from a thermally conductive and electrically insulative material, an electronic assembly having at least one light-emitting element mounted thereto, the electronic assembly in thermal communication with the rear housing component, and a lens mounted to the rear housing component and forming a watertight seal therebetween, the lens and the rear housing component enclosing the electronic assembly. At least a portion of the rear housing component conducts heat away from the electronic assembly to cool the electronic assembly. Heat-radiating structures are provided on the rear housing component for dissipating heat conducted by the rear housing component. The electronic assembly could be mounted to the rear component by a thermally conductive adhesive. A latch could be provided on the rear housing component or a bezel of the light, and is operable to selectively install or remove the light from an installation location. One or more optical components, such as light culminators, an internal collimator lens, and/or light pipes could be provided for enhanced illumination. An optically-transparent potting compound could be used to encapsulate the at least one light-emitting element and/or the electronic assembly. A cable attachment assembly could also be provided for creating a watertight seal between the rear housing component and the cable, and terminal posts could be included for attaching conductors of the cable to the electronic assembly.
摘要:
Methods and systems to simulated a plurality of airline information systems (AISs) to test an AIS under test (AISUT), including to send and receive messages between the simulated AISs, and to send messages to and receive messages from the AISUT, in accordance with communication parameters associated with the corresponding AISs and AISUT. The AISUT and/or the simulated AISs may be stimulated to cause interaction with the AISUT, and resultant messages and information may be recorded. Stimulation may include controlling a web browser to interact with a web application of the AISUT. AISs may be represented as travel system objects, which may be associated with corresponding AIS-specific message handling and reporting parameters. Message processing logic may be configured to process messages, such as booking request messages, directed to a plurality of the simulated AISs, and the travel systems and the message processing logic may be modifiable independent of one another.

A birdseed dispenser and birdfeeder incorporating the same are provided. The dispenser has a base assembly mounted to a first opening formed in the sidewall of the birdseed reservoir, including a front plate having a second opening formed therein, a flange extending around the second opening and projecting away from the front plate, and an end wall supported by the flange such that the flange and end wall together define a chamber. The dispenser also includes an apertured piece received in the chamber having a first seed aperture of a first configuration and a second seed aperture of a different configuration. The apertured piece is moveable between a first orientation, which places the first seed aperture in a seed accessible state permitting birds access to the seed, and a second orientation to place the second seed aperture in the seed accessible state.

An air bag restraint system is housed within an interior trim product with a hidden door that is opened when an air bag is inflated for deployment into the passenger car or a vehicle. The door is formed in a reinforced segment of a layer of low density rigid foam material that forms the load bearing support for the interior trim product and a backing for an outer skin or decorative surface that forms the outer cover of the interior trim product. The hidden door is formed by cast in place segments in the reinforced segment of the layer of low density rigid foam material a door hinge segment and a weakened tear seam segment which separates when the air bag impacts thereagainst to tear the outer skin for forming an opening therethrough for deployment of the air bag into the passenger compartment of a vehicle.
摘要:
A shock energy absorber includes, in one example, a cylinder having a closed end and an open end, a sleeve fixed about the open end of the cylinder, and a damping material in the form of an ultra high molecular weight polyethylene material in the cylinder. A plunger is positioned to be driven into the damping material via the sleeve. When the plunger is impacted and driven into the damping material, the damping material changes from a solid to a viscous fluid state thereby enabling absorption of a significant amount of energy.
