A sheath for constructing a reinforced concrete pile, characterized in that the sheath is formed by at least one circular knit having a series of meshes helically positioned so as to form a pipe. A method for constructing a reinforced concrete pile includes excavating to form a well, inserting one end of a reinforcing rod in a sheath, positioning the sheath on an area of the rod and introducing the rod into the well, installing a tremie pipe inside the rod, and filling the well with concrete using the tremie pipe.

Embodiments of the invention are directed to a breakaway clasp and clasp components that may provide a quick release closure mechanism. The breakaway clasp may include a first clasp component having a coupling portion and an attachment portion; and an identical second clasp component also having a coupling portion and an attachment portion. The attachment portions may be configured to coupled to a portion of an article, such as a necklacomprisesce or bracelet, and the coupling portions are configured to releasably couple to each other, thereby forming a closure. Each coupling portion comprising two, identical hemisphere elements and a connecting section that connects the two hemisphere elements. The hemisphere elements and connecting section may define a receiving cavity configured to receive at least a portion of the hemisphere elements of the other clasp component.

Embodiments of the invention are directed to a toy knitting device and a knitting kit including the toy knitting device and a breakaway clasp. The knitting device comprises a knitting body having an interior chamber in which a needle holder is rotatably coupled to the knitting device. The needle holder comprises a plurality of needles configured to move up and down the side of the needle holder as the needle holder rotates to grasp a knitting strand being fed into the interior chamber of the knitting body. The needle holder rotates by a plurality of engaged gears coupled to either an automated motor for automated rotation or a hand knob or crank for manual rotation. The needle holder comprises a center aperture through which the knitted product that is configured to receive an embellishment to be embedded within a hollow interior of the knitted product is inserted.

A knit fabric suitable as a reinforcement for elastomeric articles comprises a plurality of reinforcement yarns wherein each course of the fabric comprises either a first or second yarn, the modulus of the first yarn being different from the modulus of the second yarn, and the courses comprising the first and second yarns are arranged in one of the following sequences, (a) alternating courses comprise first and second yarns respectively, (b) the courses form a repeat pattern of, in order, a course comprising a first yarn, two courses comprising a second yarn and a course comprising a first yarn or (c) the courses form a repeat pattern of, in order, a course comprising a second yarn, two courses comprising a first yarn and a course comprising a second yarn.

The method provides for arranging a pick-up member for the tubular knitted article (M) coaxially with the needle cylinder, when knitting has been completed. The pick-up member (23) is provided with a plurality of pick-up hooks (25A, 25B) arranged according to a circular ring subdivided into two circular half-rings that can be overturned over each other. The tubular article is engaged by the pick-up hooks while the stitches of the last course of the knitted article are still held by the needles (5) of the knitting machine. The stitches of the last curse are then removed from the needles and the tubular article is removed from the needle cylinder (3) by means of the pick-up member (23). The two half-rings of pick-up hooks are overturned one onto the other, putting one of two opposite edges of the toe of the tubular article onto the other. The two edges are then sewn or linked.

A seamless circular knit fabric (10) comprising an elastic yarn is provided. The fabric (10) has a continuous circular knit through the length thereof. The circular knit fabric (10) further includes a cured cushion filling (12) inside the circular knit fabric (10) and bonded thereto. The method of making same comprises knitting a yarn to produce a continuous length of circular knit fabric (10), and injecting a curable cushion filling in a pre-cured state inside the circular knit fabric (10). This method uses a circular knit fabric forming machine assembly comprising a circular knitting machine and an injector.
