Abstract: A beach trolley includes two lateral arms, a central arm therebetween and a pulling arm that is aligned with the central arm. Each of the two lateral arms and central arm having a removable inflatable wheel at one end and being joined at the other end for pivotal movement between a trolling configuration wherein the two lateral arms and the central arm generally lie within a same plane and a compact configuration wherein the two lateral arms and the central arm are generally parallel. The pulling arm is joined to the two lateral arms and the central arm for pivotal movements towards and away the two lateral arms and the central arm.

Abstract: A valve for controlling the flow of materials is provided. The valve has a valve body having a bore, a guide attached to the valve body, a gate movable within the guide into and out of the bore, and an actuator for the gate, the bore of the valve body having a profile where the gate enters the bore, and the gate having a concave leading edge conforming to a profile of the bore. The valve may be used in throttling applications.

Abstract: An intervertebral fusion device comprises a cylindrical body of porous TiNi and having a uni-directional porosity defined by a plurality of slender pores extending in a generally vertical direction across an intervertebral space between a pair of adjacent inferior and superior vertebrae.

Abstract: Process for making a cement mixture containing fibers wherein a paste is formed by mixing cement and, per 100 parts by weight of cement, approximately 5 to 20 parts by weight of a first pulverized material of which the grains have an average diameter of between 1/5 and 1/10 of the average diameter of the grains of the cement and approximately 20 to 35 parts by weight of water. The paste is then mixed with reinforcing fibers. The paste may also include a second pulverized material the average grain diameter of which is between 1/5 and 1/10 of the average diameter of the first pulverized material. The invention further includes products made from a cement mixture manufactured according to one of the foregoing processes.
