Abstract: An equine leg conformation is altered by bracing the hoof against shifting movement while standing on a supporting surface, wedging the hoof to tilt it with respect to the surface into an attitude which serves to provide a desired altered leg configuration, and altering the support for the leg to provide a hoof attitude in normal use equivalent to the aforesaid attitude. Apparatus for use in altering the leg conformation includes a base providing a supporting surface for the hoof, means on the base for bracing the hoof against shifting movement, and wedge means advanceable on the base in the direction of the bracing means for tilting the hoof with respect to the supporting surface into an attitude which serves to provide a desired leg conformation.

Abstract: A hammock-like portable and collapsible sleeper for use in a motor vehicle having a passenger compartment with doors on opposite sides thereof, which sleeper is adapted to be suspended between the doors and above the seating area in the compartment, includes a fabric body for supporting the user, a stop member adjacent to each of opposite ends of the sleeper body, flexible connecting means interconnecting each of the stop members and the sleeper body and being sufficiently thin for interposition between the tops of the doors and the vehicle body with the doors closed tightly, and means for adjusting the length of the sleeper measured between the stop members. The sleeper is mounted for use with the connecting means interposed between the doors and the body of the vehicle and with the stop members abutting against the outside of the vehicle at the joints between the doors and the vehicle body for supporting the sleeper body in the compartment.

Abstract: An airport complex comprising a main multi-level passenger terminal having peripheral gates for the enplaning and deplaning of passengers and cargo. A cargo building which is disposed in close proximity to the passenger terminal greatly shortens the time factor which usually is involved in transporting cargo to and from the passenger terminal. The airport complex is designed principally to accommodate ultra large aircraft of the jet-propelled type and novel facilities are provided for routing enplaning cargo on a priority basis from an arriving jet to a departing jet through cargo-handling facilities which are disposed within the passenger terminal, and also for routing enplaning cargo from the cargo building to a departing jet through the passenger terminal, likewise on a priority basis.

Abstract: A method for removing waste pieces from a pre-cut sheet having cut portions and waste pieces therein, includes the steps of conveying the sheet and stripping needles along respective substantially parallel rectilinear paths and at the same rate of travel, impaling the waste pieces on the needles during the conveying step, and thereafter separating the waste pieces by moving the needles rotatively relative to the cut portions.

Abstract: A heat exchange attachment is wound around a flue pipe for heat transfer from the pipe to the surrounding atmosphere. The attachment includes a pliable elongated band of conductive material having a longitudinally elongated inverted channel-like projecting portion, a longitudinally elongated strip-like contacting portion adjoining the projecting portion therealong on either side thereof, and a longitudinal series of spaced apart transverse cuts dividing the projecting portion into a longitudinal series of individual projecting members. The contacting portions are disposed substantially in surface contact with the outer surface of the pipe, and the members project outwardly into the atmosphere surrounding the pipe with the adjacent edges of successive members spaced apart for air flow between and within the members. The attachment may be mounted on a flue pipe by screw fastening means.

Abstract: A method of effecting venipuncture in the human body includes the steps of cooling the skin over a venous area of the body by applying a cold pack thereto and providing on the cooled skin in heat exchange relation thereto a layer of an enantiotropic cholesteric liquid crystalline phase material exhibiting a mesophase color change at a temperature reached by the skin due to venous blood flow, warming the cooled skin by venous blood flow in such area thereby to produce a mesophase color change in the material delineating a vein therebeneath, and directing an instrument for venipuncture to a site in such area indicated by the delineation to constitute the location of a vein.
