Abstract: The disclosure pertains to a method and apparatus for controlling microbial growth in air handling systems employing heat exchanging coils, water pans, or the like, exposed to moisture and subject to microbial contamination. Condensation apparatus located within a chamber defined in an air handling system is disinfected by temporarily interrupting normal air flow, sealing the chamber with respect to the air handling system, introducing an anti-microbial growth gaseous disinfectant into the chamber, removing the anti-microbial gas from the chamber after disinfecting the condensation apparatus and then restoring normal air flow through the chamber. The preferred anti-microbial gas is produced by using an ozone generator in conjunction with an auxiliary air flow system.

Abstract: The invention pertains to a fiber optic lamp system such as those employed in medical diagnostic systems using a cabinet containing a power supply having a front extendible drawer containing a 250 watt focused beam metal halide arc lamp mounted in a removable bracket which includes a sensing tab extension. The bracket sensing tab operates an electrical interlock switch when the proper lamp is properly installed. The interlock switch controls power to the system whose circuit includes pin and floating sleeve electrical connectors which automatically directly completes the circuit to the arc lamp upon the drawer being closed. The amount of light transferred to the fiber optic cable is optimized by offsetting the axis of focused light with respect to the optic cable axis at the cable interface.

Abstract: 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.

Abstract: An auxiliary knob used in conjunction with camera focusing knobs to improve the focusing operation and improve access for focusing. An elastomeric body includes a recess frictionally receiving the camera focusing knob, and a knob turning surface defined upon the elastomeric body of a diameter substantially greater than the diameter of the camera focusing knob reduces the effort required for focusing and improves knob access. Reduced wall thickness lips and rims defined on the auxiliary knob facilitate cooperation with the camera focusing knob and improve the knob handling characteristics.

Abstract: 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.

Abstract: A blowpin assembly for blow molding apparatus wherein the assembly utilizes a molded article shear ring cooperating with a mold ring opening to shear the neck of the molded article following the molding process. The shear ring is mounted upon the blowpin assembly for limited radial and axial movement thereto for automatically aligning itself with the mold opening during shearing.

Abstract: The invention pertains to the method 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.

Abstract: The invention pertains to a rotary joint for use with rotating machinery, such as a dryer drum, where the joint is conveying steam by means of a rotating nipple and sealing structure. The primary elements are a stationary housing comprised of a head, body and a wear plate, a pickup tube and a spring biased nipple with a collar which engages a molybdenum lubricated reverse radius seal ring. Alignment of the components is maintained through the interaction of two guide bearings supporting the nipple, the wear plate sealing surface and the nipple collar which is spring biased against a reverse radius seal ring intermediate the wear plate sealing surface and the nipple collar sealing surface.

Abstract: A hydraulic cooling system for vehicles utilizing a hydraulic pump driven by the vehicle engine, the pump, preferably, having high and low volume chambers, a shroud adapted to be associated with the vehicle engine cooling radiator, a fan driven by hydraulic fluid pressurized by the pump for producing air flow through the shroud and the engine cooling radiator, and the hydraulic circuit between the pump and the fan motor includes a reservoir and a control valve sensitive to the engine coolant temperature. The control valve is located within the reservoir, and the reservoir is mounted upon the shroud and includes heat exchanging fins exposed to the air passage within the shroud. The entire combination of components may be pre-assembled and shipped and installed as a unit.

Abstract: A method for distributing a dredged slurry of water and solids over a substantially large area wherein the solids may be distributed in a thin environmentally acceptable manner of uniform thickness or a land area or the bottom of a water area may be significantly raised in elevation. A plurality of aerial projectors in the form of nozzles mounted upon movable supports distribute the slurry and the supports and nozzles move over the area in a predetermined manner to produce slurry distribution as desired.

Abstract: A laminated folding indicia carrier, such as a folding map, consisting of a plurality of laminated rectangular relatively stiff panels, preferably six, wherein an indicia carrier, such as a paper map, is laminated between transparent film. Selected adjacent panels are hingedly connected and pivotal through substantially 360.degree. whereby lateral panels may be selectively folded over either the front or rear face of an associated central panel, and the central panels are hingedly connected for folding over either face of the other central panel. In this manner, any of the identically dimensioned panels may be easily folded as to be visually observed while the folded configuration will be of a single panel size.

Abstract: An orthopedic pant garment consisting of identical front and rear panels wherein the outer edges of at least one of the garment leg portions is releasably interconnected by fasteners, preferably of the hook and loop type. The fasteners are spaced from each other to provide medical apparatus access to the wearer's leg or hip and as the entire vertical length of a leg portion may be opened at its outer edge by releasing the fasteners, full access to the leg is possible while preserving the patient's modesty and dignity.
