Abstract: A structure for a shoe which comprises a sole having a lip which extends upwardly from the foot engaging portion of the sole. Outside the lip is a ledge portion. The lip and ledge portion combine to fasten and support the upper to the sole by securement means. The combination is such that the width of the upper and ledge are equal resulting in that the outer portions of the upper and sole are flush. A liner is provided for the upper which engages the inner portion of the sole lip.

Abstract: An improved moccasin to be worn on a human foot is disclosed. The moccasin comprises a moccasin body including a bottom for underlining the foot, the sole curving upwardly about the sides of the foot in the periphery of the toes to form left and right side walls of the moccasin. The left and right side walls of the moccasin each have a rear portion and the rear portions are secured together and in conjunction with the sole form a heel cup. The heel cup has a generally horizontal sole portion underlining the foot and the sole portion includes an opening defined by an edge extending around this opening. A sole insert is secured in the opening. The insert includes a peripheral edge abutting the opening edge to thereby provide a substantially smooth, continuous upper surface for the foot heel to rest upon. An outer sole, which is preferably formed in a single piece by molding a polymeric material, includes a concave cavity receiving the sole of the moccasin body.

Abstract: An improved shoe construction to be worn on a human foot includes a foot bag made of sheet-like material as a unitary structure. The foot bag comprises an inner sole for underlying and that conforms generally to at least the lower surfaces of the toes, sole and heel of the foot. The foot bag also includes an outer covering for overlying and that conforms generally to the upper surfaces of the toes and the instep of the foot and to the side surfaces of the heel of the foot. The inner sole and lower edges of the outer covering meet at and are joined together at at least a portion of the periphery of the inner sole. The shoe construction further includes a flexible outer sole member that has an upper foot bed surface for underlying and supporting and that conforms generally to the lower surfaces of the toes, sole and heel of the foot.

Abstract: Sensor and reference wires are directly exposed to the airflow past a vehicle. The wires are electrically conductive, and each has a resistance varying with its temperature. A continuous fixed voltage is passed through the reference wire. A short pulse of greater constant voltage is passed through the sensor wire, the voltage of sufficient magnitude to cause the rapid heating of the sensor wire during the pulse. The resultant rate of heat of the sensor wire, and its final temperature at the end of the pulse, is determined by whether ice or water is on the sensor wire. Circuitry is provided to generate an ice present signal when the difference in current flow during the pulse through the sensor wire and through the reference wire is of such magnitude and sign as to indicate that ice was in contact with the sensor wire. Due to water's heat of fusion, the effect of ice on the sensor wire is readily distinguished from the effect of water.
