Abstract: The invention relates to a driving mechanism meant for equipping a kayak-type boat and useful in sports halls, for measuring the rate of travel during training. According to the invention, the mechanism comprises a drum (1) provided with some grooves (2) representing the path between two helical windings on which a tappet (3) attached to a slide (4) with some guiding rolls (5) travels. By the displacement of the oarsman's seat, a translation motion is imparted to the tappet, said translation motion being converted by the claimed mechanism into a rotation motion imparted to the shaft (6) of the drum (1) which, by an elastic joint (7) transmits the rotation to the propelling screw (8) of the boat. A moment of inertia is imparted during the running of the mechanism, using a flywheel (9) mounted onto the shaft, said moment of inertia ensuring the fluency of the motion and a good running condition for the cam-drum-translation tappet mechanism.

Title: Multifunctional orthodontic implant with elastic head
Inventor: SZUHANEK CAMELIA-ALEXANDRINA
IPC: A61C8/00
Filed: 2010-09-06
Abstract: The invention relates to a screw-type orthodontic implant. According to the invention, the implant has some orifices (4) cut in a zone (3) of a head (B) having hexagonal or squared cross-section shape, said orifices (4) being confined by some walls of rectangular or squared cross-section shapes which ensure, by means of some wires used during treatment as springs, the transmission of stretching, compression or bending strain to the tooth and thus generating version, translation, rotation, intrusion or extrusion stress, the orifices (4) being continued in the longitudinal plane with some recesses (5) ensuring the elasticity of the head (B), over which there is applied a closing and clamping bracket (6) anchored into a circumferential recess (7) which provides immobilization of orthodontic springs.

Title: Process and mixture for superficial hardening of steel piece
Inventor: CORABIERU ANIŞOARA
IPC: H05B6/02
Filed: 2013-01-11
Abstract: The invention relates to a process used for the combined superficial processing, in liquid and solid phase, of the pieces made of steel and to a hardening paste used within the process. According to the invention, the process has three stages: a. micro-alloying the piece directly from the liquid phase, by means of the micro-alloy paste deposited on the walls of the casting mould, b. the piece micro-alloyed from the liquid phase (6) is coated with a hardening mixture (3) and is centered into the inductor (5) so that, when the high frequency electric current (7) passes, the currents (1) induced by the lines of electromagnetic field (9) carry out the piece heating, allowing the formation, by structural modifications, of the superficial hardened micro-alloyed layer (8) and c. in the last stage the final thermal treatment is carried out, being based on quenching and tempering in various embodiments, depending on the piece stress and use conditions. As claimed by the invention, the hardening mixture consists of 35% metallic powders and 65% carburization elements.
