Abstract:
A damper assembly that produces bi-directional damper door movement from a single-direction motor is provided. Bi-directional rotation of the damper door is enabled by a cam slot on an end of the damper door that is engaged by a motor-driven drive cam having a drive pin extending into the cam slot. As the single-direction motor collectively rotates the drive cam and the drive pin, the drive pin reciprocates within the cam slot. This causes sealing flanges and the damper from the damper door to alternatively engage under a positive pressure and disengage from one another as the damper door is rotated bi-directionally.
Abstract:
A timer control apparatus for use in an appliance is provided. The timer control apparatus includes a timer having a timing motor, a user interface including a setting indicator and option switches, and a delay circuit associated with the timing motor. The delay circuit is operable to halt the timing motor and to start the timing motor such that the timer control apparatus delays progression of the timing motor. The delay circuit can halt and start the timing motor at regular intervals, irregular intervals, according to a timing pattern, based on the setting indicator, and/or based the option switches. By delaying the timing motor, travel or progression of the setting indicator between settings is reduced.
Abstract:
A multiport valve has a stemshell rotatable within a valve body with two columns of ports arranged in a planar array. An extra port extends external to the array and inlet ports communicate with selected outlet ports. The stemshell has lateral channels and longitudinal channels which cooperate with the ports at selected angular positions to provide desired inlet/outlet flows while preventing intermixing within the valve.

Abstract:
The subject disclosure is directed towards a technology in which a mobile device service plays background audio as instructed by a third party audio player application. The service continues to play background audio after the audio player application is deactivated from the foreground, e.g., as another application becomes the foreground application. Also described is launching agents to obtain additional information and/or to handle custom audio formats, and handling of user requests from a universal (system) volume control or the audio player application (when in the foreground).
Abstract:
The present invention relates to an immunogenic conjugate comprising a carrier molecule coupled to an autoinducer of a Gram negative bacteria The immunogenic conjugate, when combined with a pharmaceutically acceptable carrier, forms a suitable vaccine for mammals to prevent infection by the Gram negative bacteria The immunogenic conjugate is also used to raise and subsequently isolate antibodies or binding portions thereof which are capable of recognizing and binding to the autoinducer. The antibodies or binding portions thereof are utilized in a method of treating infections, a method of inhibiting autoinducer activity, and in diagnostic assays which detect the presence of autoinducers or autoinducer antagonists in fluid or tissue samples.

Abstract:
A method of cleaning or protecting surfaces by treatment with compositions comprising N-(3-oxododecanoyl)-L-homoserine lactone (OdDHL) blocking compounds and/or N-butyryl-L-homoserine lactone (BHL) analogs, either in combination or separately.
Abstract:
A motor driven appliance timer utilizing a cam program disk and snap action switches is provided. The motor may be externally energized, or may be energized based on integrated electronics within the appliance timer. Rotation of the program disk by a user to allow selection of a desired appliance cycle is accommodated by a clutch subassembly that allows bidirectional rotation of the program disk without requiring that the user pull or push the control shaft before rotating the program disk. The timer of the present invention may utilize either impulse or constant drive mechanisms to rotate the program disk. The use of snap action switches minimizes the possibility of tack weld failures due to switch teasing.
Abstract:
Autoinducer molecules, e.g., N-(3-oxododecanoyl)homoserine lactone, for Pseudomonas aeruginosa are described. The molecules regulate gene expression in the bacterium. Therapeutic compositions and therapeutic methods involving analogs and/or inhibitors of the autoinducer molecules also are described. The molecules are useful for treating or preventing infection by Pseudomonas aeruginosa.
