Match head formulations suitable for the production of safety matches and matches that may be struck anywhere are described in which chromium compounds, sesqui-based phosphorus compounds, sulphur compounds and oxides of zinc are absent. In their place is described the use of either amorphous phosphorus or, in the case of match head formulations suitable for the production of safety matches, an iron phosphade known as ferrophosphorus. These formulations are environmentally friendly both in manufacture and use. Environmentally friendly match head formulations which may be brightly colored are also described.
expander housing. A first heat transfer fluid circulation system removes heat from the compressor housing and expels it to the ambient atmosphere. A second heat transfer fluid circulation system removes heat from the automotive interior and expels it to the expander housing. Each of the compressor housing and the expander housing contains an equal number of cylinders. Respective cylinders in the compressor housing and the expander housing are fluidically connected to one another; and the reciprocal movement of pistons disposed in these respective cylinders is maintained in a specified phase relationship.
5477476 5478370 POWER-CONSERVATION SYSTEM FOR COMPUTER PERIPHERALS Schanin David; Billig Richard R San Carlos, CA, UNITED STATES assigned to Bayview Technology Group Inc A power conservation system (PCS) includes a data handler, a controller and a power switch. The data handler is located between a host network and a network printer, while the power switch is between an AC power source and the printer’s power input. The PCS can thus shut down the printer during periods when no data is being sent to the printer. The PCS monitors data to and from the printer, allowing it to track the printer’s state and to capture its network identification. State tracking permits the PCS to emulate the printer when it is down and when it is booting. Additionally, the information stored in a state memory of the data handler can permit the printer’s last ready state to be reconstructed after it turns on and boots to a ready state. In some cases, the data handler can answer network requests without turning on the printer. Thus, the PCS provides for effective power conservation while remaining invisible to a user.
PULLEY DRIVEN STIRLING CYCLE AUTOMATIVE AIR CONDITIONER SYSTEM Horn Stuart B Oakton, VA, UNITED STATES assigned to Advanced Refrigeration Technology An automotive air conditioning system utilizes environmentally safe gases as the working fluid for a Stirling cycle refrigeration unit. The Stirling cycle refrigeration unit includes a compressor housing and an
Spangler Michael J Sandwich, IL, UNITED STATES assigned to Amoco Corporation The invention provides an improved method for producing synthesis gas from lower alkanes which utilizes molten baths as reactors. A molten metal oxide bath delivers oxygen to a feed stream containing lower alkanes and enhances oxidation of the lower alkanes to produce carbon dioxide and a molten elemental metal. In a molten metal bath, the metal is regenerated to metal oxide by contact with a regenerant such as air. Heat evolved in the molten baths is transferred to an endothermic reactor where a portion of the carbon dioxide is converted to a mixture of carbon oxides and hydrogen.
5478413 ENVIRONMENTALLY FRIENDLY COATING COMPOSITIONS
METHOD FOR PRODUCING SYNTHESIS GAS
Mosser Mark; Eddinger Kevin B Perkiomenville, PA, UNITED STATES assigned to Sermatech International Inc An aqueous phosphoric bonding solution and coating composition slurry which are environmentally friendly in that they are generally free of molybdate or chromium. Yet the solution is stable with respect to inorganic metal particles, especially aluminum which are admixed to the bonding solution for the preparation of the coating slurry. The metal coated parts and the method of coating the parts with the coating composition are also described. The parts have very satisfactory properties.
