12 volt fluorescent light fixture

Recreational vehicle light fixture

The invention pertains to the method and apparatus for forming air flow control orifices in a patient body temperature regulating blanket consisting of an inflated envelope defined by thin plastic film wherein temperature controlled air flows through the blanket orifices upon the patient's body. The blanket side disposed toward the patient is pierced by a sharp pointed punch having a plurality of intersecting facets defining sharpened intersecting edges. The punch apex and facet intersecting edges are related to the moving film in such a manner that the penetration of the punch forms a plurality of flexible valve flaps, and the valve flaps engaging the patient's body will be retained in a closed condition to restrain air flow through those orifices engaging the body to prevent exposure to excessive air temperatures.

Method of controlling air flow from an inflated blanket

A light fixture having an arcuate convex lens includes a decorative strip extending across the lens convex configuration usually adhered thereto by an adhesive mounted on the strip. Decorative strip end retainers are homogeneously defined at lateral edges of the lens and comprise recesses having an opening adjacent the lens exterior convex surface whereby the decorative strip ends are received within the recess opening and the recesses retain the decorative strip end preventing the ends from pulling away from the lens surface.

Light fixture with trim strip retainer

A disposal pneumatic temperature controlled blanket consisting of flexible upper and lower sheets interconnected at their peripheries to define an inflatable envelope. The lower sheet outer surface is provided with a friction producing layer and a plurality of orifices are formed in the lower sheet and layer whereby temperature controlled pressurized air introduced into the envelope will be distributed through the orifices upon the patient's body to regulate patient body temperature. The envelope sheets are staked or tacked intermediate the peripheries to control inflation and distribute the air and the location of the tacks define primary and secondary air passages to quickly and uniformly distribute the air with a minimum of heat loss to various blanket locations so as to achieve substantially uniform patient body temperature exposure.

Wall light fixture

A direct current power supply system for recreational vehicles having an auxiliary chargeable battery wherein a transformer powered converter is utilized to rectify alternating current into direct current, and where the circuitry includes a battery fast charging circuit and control utilizing sensing means for automatically terminating battery fast charging upon predetermined conditions being attained. Fast charging of the battery is accomplished through a converter transformer of economical construction having a variable voltage output controlled in dependence by the fast charging operation.
