Patent EP-0381801-A1 (EP)
Inventor: FELDINGER MARTIN PROF DR
IPC: F02M69/52
Filed: 1989-02-14
Abstract: The invention proposes a device making it possible by structurally simple means to correct the mixture composition for a load variation of a combustion engine with which a mixture-forming device (4, 6, 8, 9, 11) is associated. 
<??>The device is characterised in that the mixture-forming device has a metering unit (6) for the fuel with a feed-side fuel delivery line (5) and a discharge-side fuel delivery line (7), and a movably supported metering element (18) is arranged in the metering unit (6), which element clears the position-dependently variable fuel flow cross sections in the metering unit, the metering unit being connected via an aperture (31), sealed by means of a movable compensating element (33), to a compensating chamber (32), which is connected via a branch line (34) to the discharge-side fuel delivery line, and the movements of the metering element and the compensating element being intercoupled in such a way that a movement of the metering element in the direction of an enlarged fuel flow cross section leads to a movement of the compensating element reducing the compensation chamber and a movement of the metering element in the direction of a reduced fuel flow cross section leads to a movement of the compensating element enlarging the compensation chamber.

Abstract: Un ruban (40) n'est entraîné le long de la station d'impression d'une imprimante (12) que lorsqu'une tête d'impression à mouvement alternatif (22) se déplace de droite à gauche par rapport à l'imprimante (12). Une courroie de synchronisation sans fin (46), qui effectue un mouvement alternatif avec la tête d'impression (22), provoque la rotation d'une poulie à engrenage (48) qui est couplée avec une roue intermédiaire (66). Cette dernière est soutenue par une paire de doigts saillants (80, 82) d'un plateau (68) qui pivote sur la tige (56) supportant la poulie d'engrenage (48). La roue intermédiaire (66), maintenue couplée avec la poulie d'engrenage (48), réagit au sens de rotation de la poulie d'engrenage (48) par l'effet d'entraînement des extrémités (84, 86) des doigts saillants (80, 82) sur la surface inférieure de la roue intermédiaire (66), ce qui provoque un mouvement oscillant du plateau (68) en accord avec le sens de rotation de la poulie d'engrenage (48), de telle manière que la roue intermédiaire (66) n'est couplée avec un engrenage d'entraînement de ruban (88) que lorsque la tête d'impression (22) se déplace de droite à gauche par rapport à l'imprimante (12).

Title: Dental laser assembly.
Inventor: VASSILIADIS ARTHUR
IPC: A61C5/00
Filed: 1989-08-25
Abstract: A dental laser assembly is disclosed for use in eradicating carious lesions in teeth, the treatment of sensitive teeth, as well as the removal of soft tissue. The laser assembly includes a housing having a cavity in which a pulsed laser is contained. The laser is excited so that the laser emits a laser beam along a predetermined axis that is in line with a fiber optic delivery system and at a pulse rate of one to 10,000 pulses per second and an average power variable from zero to 50 watts. A handpiece is dimensioned to be inserted into a human mouth while an optical fiber optically connects the laser output to the handpiece. The laser assembly also includes a continuous output aiming laser which, upon activation, provides a continuous laser aiming beam coaxial to the treatment beam. Both beams are then introduced into a fiber optic delivery system.

Inventor: GRAM OLE
IPC: B42F7/02
Filed: 1989-10-17
Abstract: The invention refers to a folder (1), intended for sheets (6) of a specific size. The folder (1) is made of a foil of plastic or other material. The foil is folded to form a spine (2), a front side (3) and a back side (4). A joint (10) is provided at the top edge (8) of the folder (1) to join together the front (3) and back (4) side. A corresponding joint (11) is provided at the bottom edge (9). Both joints (10, 11) are placed at a distance of preferably a little less than a sheet margin from the spine (2) of the folder (1), and at a minimum distance, in the spine direction, which is close to and preferably a little shorter than the length (17) of the retained sheets (6). If the distance is shorter, then the joined areas (10, 11) at the top (8) and bottom (9) will press downwards and upwards respectively against the top and bottom edges of the sheets (6), by which arrangement a sufficient retention of the sheets (6) is achieved. Insertion and removal of sheets (6) can be quick and easy and they can be turned over like leaves in a book.
