IPC: A61C11/02
Filed: 1994-12-22
Abstract: Adjustable condylar balls (1) are mounted on support pins (2) which project into a bush (4) in a vertical frame (3). Following adjustment, a plaster mass is used to fix the structure in place. A further bush (6) which has a collar (8) is slid over the pins and is fixed by a securing screw (7). Within the condylar housing (9) of the articulator is a through bore (12) in which a support bush (13) with a collar (14) is located. The collar matches a countersunk indentation (15) in the upper side of the condylar housing. The bore serves to locate a retaining mechanism namely a flat plate (16) fixed at right angles to a shaft (17) in the bore which connects to a hand rotated knob (18). Located on the flat plate is a hole which has a smaller diameter than the condylar ball and which retains the ball in the three degrees of freedom of movement.  A slot in the underside of the condylar housing serves as a location for the flat plated when it is moved under the force of a spring (19) mounted between the hand piece and the collar. Simulation of jaw movement is monitored through relative movement in the sagittal plane by joint guide rails (10) and in the transverse plane through Bennett guide rails.

Patent WO-8601612-A1 (WO)
Title: Projection system for a guide beam
Inventor: SKROBOL CHRISTIAN
IPC: F41G7/26
Filed: 1985-08-29
Abstract: A projection system for a guide beam in which a lens (10) forms an image of a partial zone of a star target (13) turning around a rotation axis (16) which is lit by a light source (11) in a space (15), so that an object which has to be guided indicates its position in a plane which is perpendicular to the axis (17) of the guide beam, by means of the corresponding modulation frequency of the light beam of the figure. The projection system described is characterized by the fact that, in order to suppress higher orders than the first order, the separating edges between the radial beams which practically do not influence the light beam of the star target (13) and those which do influence the latter are designed so as to have a gradual outline. This offers the advantage that the pattern of intensity always exhibits simple maxima, so that the object to be guided can immediately indicate the frequency, and hence its relative position in a plane which is perpendicular to the axis of the guide beam. In a particularly advantageous development of the discovery, the gradual progression is formed by a second modulation pattern which runs in a radial direction, the local frequency of which is greater than that of the radial beams of the star target.
