Abstract: A device for ground stabilizing in hydraulic engineering comprises a structural steel mat to the bars of which are clipped grass support elements which have an upwardly open trough-shape in which grass-like ribbon elements are held by a further bar fitted into the trough and gripped thereby.

Abstract: A tie anchor for use in reinforced sandwich panels of cast concrete, to support a face panel on a carrier panel by reaching through an intermediate insulating panel, the tie anchor being a sheet metal stamping with a central A-shaped end portion on one axial end and a V-shaped recess flanked by two tapered end portions on the other axial end. Hook portions formed of the tapered end portions are engageable over a rod of a reinforcing steel rod mesh and attachable thereto by means of positioning rods which are inserted through transverse positioning bores in the hook portions.

Abstract: A needle for knitting or crochet includes a needle tip of a material resistant to bending and a flexible loop-receiving rod secured to the rear end of the needle tip. A node is provided at the rear end of the loop-receiving rod. The needle includes a loop braking element slidable positioned on the rod. The node precludes the loop braking element from slipping off the rod. The loop braking element is a ring or a disk formed with a radial bore receiving the rod therethrough and a recess in which the end of the rod can be snapped.
