The present invention describes a solar powered garden lamp (100,100a,100b). The lamp (100,100a,100b) includes a lamp assembly, a solar panel (192), a rechargeable battery (150), a sunlight-hour switch (154), an LED (146a,146b) and a control circuit (140). In use, a user estimates the number of hours of sunlight incident on the solar panel (192) and the sunlight-hour switch (154) is calibrated by applying a weather variability factor on a battery charger (142) capacity that is connected to the solar panel. The solar panel (192) converts solar energy into electric power to recharge the battery (150) during the day so that the battery (150) has sufficient power to light up the LED (146a or 146b) at a predetermined brightness continuously from dusk to dawn.

Formulations of the present invention contain compounds of Formula (I) that are used as Sulfur Scale Inhibition and/or Removal Agents in the treatment of Industrial Water Systems.

Provided is an auxiliary boiler exhaust structure for a micro combined heat and power unit comprising an electricity-generating Stirling engine which is heated by means of an engine burner, and comprising a hot-water-generating auxiliary boiler which is provided on the upper part of the Stirling engine and has a sensible-heat heat exchanger and a latent-heat heat exchanger; wherein a flow path is formed that links the latent-heat heat exchanger and an engine head for discharging the exhaust gas that has heated the Sterling engine, and the flow path is constituted such that heat exchange is effected while the discharging exhaust gas is flowing from the upper part to the lower part of the latent-heat heat exchanger.

A synthetic resin composition for forming an article, such as a container or bag for garbage, or electrical wiring insulation, which repels animals such as rodents, opossum, cats, dogs, and birds. The composition includes a thermoplastic polymer and from 10 to 15,000 ppm by weight of an odorant compound such as a salicylic acid ester, menthol, corn mint oil, eucalyptus oil, and camphor, and combinations thereof. The resin composition may comprise more than one thermoplastic polymer, polyethylene and ethylene/vinyl acetate copolymer being preferred first and second thermoplastic polymers, respectively. In a method for forming the synthetic resin composition, the compound is added to the second polymer in a ratio of about 1:2 parts by weight to form a master blend that then is added to an amount of the first polymer at a master blend percentage of about 1.5%.

Case accessories for portable electronic devices are disclosed. In some embodiments, a case accessory may include a base configured to sit on a working surface, a support coupled to the base and configured to support a portable electronic device in an elevated position, a rotational mechanism coupled to the support configured to allow the holder to rotate in one or more directions relative to the support, and a holder coupled to the rotational mechanism and configured to secure the portable electronic device.

A high temperature-stable and highly purified cross-linked (optionally > 70% β-β linked) tetrameric hemoglobin with high efficiency of oxygen delivery suitable for use in mammals without causing renal injury and vasoconstriction is provided. The dimeric form of hemoglobin is degenerated and purification processes are performed on red blood cells from whole blood. Controlled hypotonic lysis in an instant cytolysis apparatus prevents lysis of white blood cells. Nucleic acids from white blood cells and phospholipids impurities are not detected. Blocking of reactive sulfhydryl groups by a sulfhydryl reagent is performed in an oxygenated environment. Flowthrough column chromatography removes different plasma protein impurities. N-acetyl cysteine is added to the cross-linked tetrameric hemoglobin to maintain a low level of met-hemoglobin. The stabilized hemoglobin is preserved in an infusion bag with aluminum overwrap to prevent formation of inactive met-hemoglobin from oxygen intrusion. The product finds use in tissue oxygenation and cancer treatment.

Moisture is retained in cooked or thawed food by adding to the food an aqueous suspension of animal muscle protein obtained from animal muscle tissue. The aqueous suspension is obtained by mixing comminuted animal muscle tissue with a food grade acid to form an aqueous acidic solution of animal muscle protein. The acidic solution is mixed with a food grade base to precipitate the protein in an aqueous composition. The precipitated protein then is comminuted to form an aqueous suspension of comminuted animal muscle protein.
