Abstract: A compact anesthetic syringe is disclosed for injecting a medication under high pressure into a confined space comprising a lower cylinder (15) to receive a carpule (35) containing a medication and having a cannula assembly (27) at one end which penetrates the carpule. An upper cylinder (17) contains a piston rod (69) having a piston (43) which engages in the carpule. The piston rod has ratchet teeth (61) and a lever (11) pivotally mounted on the upper cylinder and a spring biased away from the cylinder has a ratchet (57) engaging the teeth. Depressing the lever (11) towards the cylinder causes the piston rod to force the piston into the carpule to eject the medication from the cannula. The arrangement provides a compact device which is simple to hold and operate in one hand and a stroke of the lever discharges a known amount of liquid.

Abstract: Nail-type fastener comprising an elongated shank (1) having three symmetrically positioned, longitudinal grooves (4) separated by longitudinal ridges (8) with a cross-sectional arcuate outer side (9), the grooves having flat, concave or cross-sectional V-shaped bottom surfaces (27,17,7). The nail has a high-flexured rigidity and high pull grip with comparatively low weight. The fastener or nail is produced starting from a cross-sectional circular nail wire stock which is profiled in two cold-rolling steps. In the first step, the nail wire passes through a first roller trio, the section rollers producing grooves into the nail wire stock. In the second step, the nail wire passes through a second roller trio, whereby a deepening of these grooves into deep grooves is brought about. Thereupon the head and the point are produced at the ends of the shank, the finished nail thereby being separated.
