Abstract:
A self-contained evaporative personal cooling device fits conformally around a user's neck or other body portion. The device includes at least one heat dissipating member that is urged conformably against the body portion to absorb heat therefrom. The device-facing side of this member preferably has a large surface area with a liquid-wickable surface. A liquid-retainable material contacts at least a portion of the wickable surface area and also defines at least one air plenum. Ambient air is moved along the plenum, preferably by a battery-powered fan. The air transfers heat from the member, cooling the user, and is exhausted from the device. A thermostat can sense temperature at the heat dissipating member to control duty cycle of the fan to prevent overcooling the user.
Abstract:
A personal groomer includes a hand-holdable housing within which is disposed a battery operated motor coupled to a cutting head assembly that protrudes at least partially from a distal end of the housing. An impeller fin assembly is attached to a lower portion of the cutting head assembly for rotation therewith when the motor is energized. Preferably the lower portion of the cutting head assembly and the impeller fin assembly are surrounded by a thimble-shaped member defining sidewall vents and having an opening in its upper surface, through which a distal portion of the cutting head assembly protrudes. A light source is mounted in the housing so as to focus light on hairs to be cut with the groomer. The groomer is cleaned by submerging the distal end of the housing assembly in water and energizing the motor. The resultant impeller fin rotation draws water into the cutting head assembly, and expels the water along with cut hairs and any other debris out the vents in the thimble-shaped member. A housing-mounted switch, preferably a pressure switch or a toggling switch, permits user activation of the personal groomer.
Abstract:
A method for converting methane to methanol is provided comprising subjecting the methane to visible light in the presence of a catalyst and an electron transfer agent. Another embodiment of the invention provides for a method for reacting methane and water to produce methanol and hydrogen comprising preparing a fluid containing methane, an electron transfer agent and a photolysis catalyst, and subjecting said fluid to visible light for an effective period of time.
Abstract:
An improved catalyst and method for the oxyhydrochlorination of methane is disclosed. The catalyst includes a pyrogenic porous support on which is layered as active material, cobalt chloride in major proportion, and minor proportions of an alkali metal chloride and of a rare earth chloride. On contact of the catalyst with a gas flow of methane, HCl and oxygen, more than 60% of the methane is converted and of that converted more than 40% occurs as monochloromethane. Advantageously, the monochloromethane can be used to produce gasoline boiling range hydrocarbons with the recycle of HCl for further reaction. This catalyst is also of value for the production of formic acid as are analogous catalysts with lead, silver or nickel chlorides substituted for the cobalt chloride.

Abstract:
A switching circuit is completed between electrical contacts by a flexible cap overlying the contact points. The cap is formed with cylindrical sidewalls and an upper end closure which has a plunger or piston-like portion extending therefrom towards the contact points. The dome section is arranged so as to arc from the cylindrical sidewalls in a direction away from the contact points so that depression of the dome will not effect collapsing of the cylindrical sidewalls for the entire extent of the contact establishing travel. The cap can deflect a metal dome to perform the contact establishment or can be composed of a resilient conductive material to directly establish electrical contact.
