Abstract: A circular knitting machine comprises a rotatable knitting needle cylinder which carries a plurality of knitting needles through knitting stations. A needle-moving jack is pivotally connected with each of the knitting needles and is movable in a needle-raising stroke and a needle-lowering stroke to effect needle raising and lowering, respectively. Each of the needle-moving jacks has a butt thereon which is received in a cam track which operates to effect the raising and lowering of the needle-moving jack. A mechanism is provided for controlling the operation of each knitting needle as it progresses through the stations. The mechanism specifically effects pivoting of the needle-moving jack so that the butt thereon is removed from the cam track. The means which effects the pivoting movement of each needle-moving jack comprises a movable selector jack which cooperates with the needle-moving jack and effects the pivoting movement of the needle-moving jack in response to actuation of electromagnetic means.

Abstract: The present invention relates to improvements in U-shaped tunnel shutterings or framing for poured concrete constituted by two half shells in the form of a right-angled dihedron, of which the edges of upper horizontal panels are connected by clamping locks and each of said edges is connected to the bottom of a vertical panel by braces of adjustable length, the reduction in length of the braces determining a reduction in the angle of the dihedron; said shutterings may be used either in the form of a complete "U" with the two half-shells connected, in which case lower parts of the two vertical panels are connected by removable horizontal bars of adjustable length, or as half-shells in which case props are used which are articulated on the free edge of the horizontal panel and rest on the ground.

Abstract: A removable cast, form or "shuttering" is provided to form "in situ" from poured concrete the portion of an outside wall, of a building disposed between the sill of the window opening of one story and the upper part of the window opening of the story directly below it. The shuttering comprises a unitary combination handleable in a single operation of either assembly preparatory to pouring concrete, or disassembly after pouring. It includes all adjustment means necessary for adjusting the assembly in all directions, and does not require any alteration to the parts of the building already constructed. The shuttering, when assembled, is characterized by having its center of gravity disposed within the building, to provide a more stable equilibrium during pouring, and by having its center of gravity, upon disassembly, displaced to the outside of the building, to facilitate its ready removal with the aid of a crane, winch or other comparable lifting means.

Abstract: An improved one-piece circular knit pantyhose having an intermediate panty portion and two integral leg portions formed from a single rotary knit tubular blank, whereof the crotch area of the panty portion is formed of more tightly knit stitches than the remainder of the panty portion to impart to the panty portion a continuous longitudinal curvature.

Abstract: The garment includes a panty portion .[.formed of fashioned gussets.]. and a pair of legs integrally knit with the panty portion. The legs may be short to provide a panty, panty girdle and the like or they may be long and provided with foot portions to form tights, leotards, panty hose and the like. .[.Fashioned front.]. .Iadd.Front .Iaddend.and rear .[.gussets.]. .Iadd.portions .Iaddend.of the panty portion are provided with knit selvage edges to form a waist opening in the garment during the knitting operation and to eliminate the need for slitting the garment in a subsequent operation to form the waist opening. Elastic yarns may be incorporated in the portion of the garment surrounding the waist opening to provide an integrally knit elastic band around the waist opening.
