A cleaning implement is provided for cleaning surfaces with a cleaning substrate. The cleaning implement includes a handle connected via a universal joint to a mop head. The mop head includes a bumper pad, which is made of a deformable and nonabsorbent material. The bumper pad can be deformed in the Z direction and within the X-Y plane. The cleaning implement can also include a motor for causing a portion of the mop head to move relative to the handle.

A method, comprising: providing a pre-filled adhesive pavement marker having a body with downwardly facing openings that are pre-filled with an adhesive; providing an adhesive pad of the adhesive on a surface of a pavement; attaching the pre-filled adhesive pavement marker to the adhesive pad to thereby adhere the pre-filled pavement marker to the surface of the pavement.

A process for preparing an oxidation/reduction catalyst system includes providing a sol-gel precursor; providing a metal oxide wash coat mixture; and dispersing the sol-gel precursor in the metal oxide wash coat mixture to provide a dispersion of sol-gel precursor in metal oxide wash coat mixture. This dispersion of sol-gel precursor in metal oxide wash coat mixture is then deposited on a support, which is subsequently thermally-treated in an oxygen-containing environment to drive off volatiles and oxidize metallic components, thereby producing a thermally-treated support. Finally, a noble metal coating is applied to the thermally-treated support.

A requirements based registration system for higher education that decreases students' time-to-degree and credits-to-degree by optimizing the registration process. After students log into the system, they are presented their student profile and degree progression information. Once that information is verified, the system displays the students' available remaining requirements to obtain their desired degree. After students specify the requirement(s) to be satisfied, the system generates fulfillment options that ensure each course selected does in fact satisfy the specified requirement(s). Upon submission of courses, the system verifies that the student is eligible to enroll in each course and also checks if any course can be used in a more restrictive requirement. The system can prevent students from registering for non-degree (ND) courses or allow a set number of ND courses, based on each student's individual profile (e.g., classification). Students must designate the reason for taking ND courses. The system automatically sets special review flags for first-time freshmen, new transfers, and students changing majors to ensure that due diligent efforts have been performed (e.g., review of transfer equivalencies) prior to registration.

An exhaust gas treatment system having an exhaust gas inlet section, an oxygen enrichment system, catalyst holding arms, and an exhaust gas outlet section is disclosed. The exhaust gas inlet and outlet sections can be designed to mate to existing exhaust gas plumbing systems for industrial facilities. The optional oxygen enrichment system helps optimize catalytic performance by maintaining excess oxygen in the exhaust gas stream and by imparting greater turbulence to the exhaust gas stream. Disposed within each catalyst holding arm is at least one catalyst coated substrate where the catalytic oxidation of formaldehyde and other volatile organic compounds occurs. The catalytic substrate can be catalyst coated bricks, particles, beads, fabrics, or filter materials. Each catalyst holding arm can be selectively closed off using upstream and downstream isolation valves. Catalyst coated substrate longevity can be increased by the inclusion of an optional filter upstream of the catalyst coated substrates.

A sensor has a plurality of carbon nanotube (CNT)-based conductors operatively positioned on a substrate. The conductors are arranged side-by-side, such as in a substantially parallel relationship to one another. At least one pair of spaced-apart electrodes is coupled to opposing ends of the conductors. A portion of each of the conductors spanning between each pair of electrodes comprises a plurality of carbon nanotubes arranged end-to-end and substantially aligned along an axis. Because a direct correlation exists between the resistance of a carbon nanotube and its strain, changes experienced by the portion of the structure to which the sensor is coupled induce a corresponding change in the electrical properties of the conductors, thereby enabling detection of crack growth in the structure.

A light sensor substrate comprises a base made from a semi-conductive material and topped with a layer of an electrically non-conductive material. A first electrode and a plurality of carbon nanotube (CNT)-based conductors are positioned on the layer of electrically non-conductive material with the CNT-based conductors being distributed in a spaced apart fashion about a periphery of the first electrode. Each CNT-based conductor is coupled on one end thereof to the first electrode and extends away from the first electrode to terminate at a second free end. A second or gate electrode is positioned on the non-conductive material layer and is spaced apart from the second free end of each CNT-based conductor. Coupled to the first and second electrode is a device for detecting electron transfer along the CNT-based conductors resulting from light impinging on the CNT-based conductors.

A pre-filled adhesive pavement marker having a body with downwardly facing openings that are pre-filled with an adhesive. An adhesive pad including an adhesive can be provided on a surface of a pavement. The pre-filled adhesive pavement marker can be attached to the adhesive pad to thereby adhere the pre-filled pavement marker to the surface of the pavement.
摘要:
The invention described herein involves a novel approach to the production of oxidation/reduction catalytic systems. The present invention serves to stabilize the tin oxide reducible metal-.oxide coating by co-incorporating at least another metal-oxide species, such as zirconium. In one embodiment, a third metal-oxide species is incorporated, selected from the group consisting of cerium, lanthanum, hafnium, and ruthenium. The incorporation of the additional metal oxide components serves to stabilize the active tin-oxide layer in the catalytic process during high-temperature operation in a reducing environment (e.g., automobile exhaust). Moreover, the additional metal oxides are active components due to their oxygen-retention capabilities. Together, these features provide a mechanism to extend the range of operation of the tin-oxide-based catalyst system for automotive applications, while maintaining the existing advantages.

A combination window assembly, screen, storm shutter and fire escape includes a fixed frame mounted into the building wall. A horizontally movable window frame, screen and storm shutter are positioned in the fixed frame, whereby each can be moved from a position covering an open portion of the frame to a position within a recess. The window assembly is operable, such that a component of the window can be opened when the window assembly is positioned in the open portion.
