Abstract: A skate base for a goal-tender's skate having blade support means and foot protective means. A skate boot is mounted on the skate base to provide the skate.

Abstract: A unitary one-piece molded plastic skate, for use with ice or roller skate runners, has a lower shell portion and an upper portion shell portion with the upper shell portion comprising a tendon guard and side ankle flaps, the tendon guard portion of the upper being integrally molded to form a hinge with the rear heel portion of the lower portion. The side ankle flaps overlap upward extensions of side walls of the lower shell portion. A mold apparatus for forming the one-piece skate boot and said mold apparatus including a core formed to the inner shape of the skate boot and having an upstanding leg portion with the thin walled sleeve fixed to the upstanding portion and having a downwardly extending skirt which, in the molding operation, is in contact at the edge thereof with the mold cavities so as to form the flaps of the upper portion but to leave a hinge portion at the heel rear.

Abstract: A closure system is provided for a front entry ice skate sports boot having a top, an ankle portion with a back, a front opening, and sides extending above the ankle bone of a wearer, and an upper with a front opening. A plurality of guide means are disposed on the upper on opposite sides of the front opening for receiving and guiding a substantially flat flexible strap. The guide means are constructed such that the strap can be laced through the guide means in such a direction that the ends of said strap are generally near the top of the boot, and substantially encircle the ankle portion above the ankle bone. A hinge movably attaches the ankle portion to the upper for limited rotation therebetween. A plurality of guide means are also disposed on the ankle portion on opposite sides of the front opening. Fastening means are positioned on the strap and include a strap adjusting part through which the strap passes.

Abstract: A molded athletic boot such as an ice skate boot or ski boot is formed of a lower portion to which is hinged an upper. The lower includes an upstanding extension on each side of the forward instep portion to which flexible straps are secured. The extensions are crossed and the straps pass through apertures in the upper to encircle the back of the boot. The straps may then be drawn tightly around the back of the boot and secured together to close the boot around the foot of the wearer.

Abstract: A system is described wherein components such as a prepolymer and a curative are delivered by means of positive displacement pumps through a special valve at the upper end of a static mixing tube. The components pass down the tube while being intermixed to form a reaction mixture which is dispensed into a mold by means of a valve at the lower end of the tube. The special valve forms part of a recirculation system which permits bypass and recirculation of each component between dispensing operations so that the pump can continue to operate at constant velocity. The static mixing tube is pivotally suspended from an arm so that its lower end may be properly positioned with respect to a mold to be filled. Special end interlocked mixing vanes are provided in the static mixing tube for convenient disassembly.
