In the latter case the shaft provides a plurality of support locations at the first edge of the support surface that are moved, in order to alternately tighten and slacken the first plurality of bands. Other disclosed apparatus and methods can tighten and slacken the second plurality of bands as well.

Abstract: Sludge can be treated by placing it in a carrier sized for bulk shipment of sludge by road or by rail. An antipathogenic substance such as lime is mixed into the sludge located in the carrier in order to treat pathogens in the sludge. At least one mixer adapted for mixing sludge throughout the carrier is employed. A dispenser such as a conduit or a loader bucket can dispense the antipathogenic substance so that the mixer can mix the substance with the sludge. The sludge is transported in the carrier either before or after the mixing with the antipathogenic substance. The mixture of sludge and antipathogenic substance is allowed to remain in the carrier long enough to treat pathogens with the substance before unloading the sludge from the carrier at a destination established for utilization, storage, transfer or disposal of the sludge.

Abstract: A surgical floormat arranged to shed fluids has a topside and an underside. The floormat is placed where a surgeon is expected to stand during surgery.

Abstract: A perovskite catalyst is prepared using a ceramic sol-sol methodology comprising preparing slurry in water of an alkaline earth metal salt, a powdered metal salt and a powdered transition metal oxide, adding a polymeric binder to form a paste, drying and comminuting the paste into a powder and heating the powder with a temperature profile to calcination temperatures. In one embodiment the slurry is formed of titanium oxide with barium carbonate and tin chloride in deionized water, and more specifically by a mixture according to Ba (1-0.05x)+TiO2+SnCl2(0.05x) where x is in moles. The perovskite catalyst is preferably used in a process for oxidative coupling of methane. Catalyst performance is enhanced through the addition of halides to the feed gas in the reaction.

Specifically, the case is mounted so that one of the sensors is inside the enclosure and the other is outside. The monitor also includes an alarm system mounted at the case and coupled to the first and the second sensor for producing a warning signal in response to the first and the second signals from the first and the second sensor signifying a temperature difference exceeding a predetermined threshold.

Abstract: A lamp electrode adapted to deliver mercury during an assembly process has a supporting electrical lead attached to the proximal end of a metallic shell. The proximal and a distal ends of the metallic shell each lie along a central axis. A container with a vitreous plug in a sealed end contains a substance for delivering mercury upon heating of the container. The sidewall of the container is attached to the electrical lead. The longitudinal axis of the container is skewed relative to the electrical lead to orient the container in a direction to reduce discharge of mercury directly toward the metallic shell. The container is heated to open it and discharge a mercury dose from the sealed end, which is prone to opening upon heating of the container.

The fixture has a spaced pair of connective devices each having a barrel with an electrical contact adapted to connect to opposite ends of the lamp. A tubular lamp cover has a light transmissive section and a light reflective section. Each section is contiguous to the other and trough-shaped. The lamp cover is rotatably mounted around the barrels of the connective devices.

Abstract: Waxes prepared from hydrogenated plant oils, such as castor, palm, and soybean, are used to prepare water based emulsions. The inventive waxes, obtained from naturally derived, renewable resources, were emulsified under anionic, cationic and nonionic conditions, producing emulsions having a solids content up to about 45% solids. When used to coat fibrous cellulosic articles, such as paperboard, the emulsions' performance was similar to emulsions containing petroleum-derived waxes. The inventive waxes have a low iodine value (between 2-5), and melting points between approximately 120-200 degrees F. (Mettler Drop Point). These waxes comprise a triglyceride whose fatty acids are predominantly stearic acid or ricinoleic acid.
