摘要： A method of making plastic containers having walls with fluid circulatable channels integrally formed therein comprises the successive steps of injecting a molten thermoplastic material in a mold cavity having a channel configuration to define, in the container being mold, walls with thicker portions defining a rib configuration, injecting a pressurized fluid throughout the rib configuration to displace molten material therein and to form a hollow channel therein, cooling the container being mold removing the molded container from the mold and cutting through the hollow channel at two spaced locations to form inlet and outlet openings to the channel to thereby enable circulation of a fluid through the channel.

摘要： The invention relates to an improvement in a snowmobile endless track belt of the type comprising a body made of an elastomeric material, an outer surface for contact with the ground and an inner surface provided with lugs for engagement with the snowmobile driving system and with at least one endless pathway that contacts a corresponding slide rail o f the snowmobile suspension. The improvement is characterized in that the elastomeric material, in at least the area which is contacted by the slide rail, is composed of rubber and of a lubricating material so that friction generat ed between the slide rail and a driven belt is greatly reduced by the presence of such lubricating material in the elastomeric material.

摘要： An endless belt for use with a heavy duty track vehicle comprises a body made of polymeric material wherein a series of longitudinally spaced guide members are integrally formed to the inner surface thereof while two rows of longitudinally spaced tread members are integrally formed to the outer surface thereof. Each tread member in each row has an outer edge area adjacent the outer edge of the body and an inner edge area terminating substantially at mid-section of the body. Each tread member of the first row is longitudinally offset relative to an adjacent tre ad member of the second row. Each inner edge area of the tread members is in vertical alignment with a corresponding one of the guide members of the inner surface of the body. Also, the pitch defined by two successive guide members differs in value from other pitches along the outer surfaces of the belt. This particular geometry of tread members and drive members is such as to reduce slitting damages to the track when driven as well as vibration.

摘要： A snowmobile steering ski consists of an elongated one-piece blow molded body formed of polyethylene, preferably ultra high molecular weight polyethylene. The top wall of the body has raised portions defining hollow sections with the bottom wall and displays a central recessed area adapted to receive the lower end of a snowmobile steering component. A pair of fixation holes are provided in lateral sides of the recessed area for fixing the steering component to the ski while further fixation holes are provided in the bottom of the recessed area for fixing a wear bar to the under face of the body.
