Patent FR-2481634-A1 (FR)
Title: Motorised lens clamp for edge bevelling grinder - uses two slides on mono-rail and driven rack and pinion associated parallel guide rail
Inventor: ASSELIN ROBERT RAYMOND MAURICE
IPC: B24B41/06
Filed: 1980-04-30
Abstract: The motor operated clamp secures the workpiece lens (7) on a bevel-grinder for spectacles. Clamping forces are normal to the major lense faces, and the lens can rotate about the resultant (H2-H2) to clamping forces in response to template (6) displacements. Two similar (1,3) slides may have a common guide rail (2), locating the jaws (4,8) on the ends of freely rotatable stub-axles (5,9). The latter are co-axial and parallel to the rail shaft (10) cantilevering from the one slide (1) to the traverse slide (3) and maintain the relationship. A motor (13)-driven pinion (12) is built into the slide and engages a shaft (10) rack (11) formation to effect the relative movement of the slides. The template (6) clamp (5A,14) may be operated by a hand screw (16-18) or may also be motor (13) operated.

Title: Welding different metals by transverse vibration of electron beams - concentrating beam on metal with high and preventing concentration on member with low thermal conductivity
IPC: B23K15/02
Filed: 1980-10-30
Abstract: In a process for welding different metals together by an electron beam, the joint to be made is fed past the beam at a speed of V mm/second. The beam is oscillated transversely across the joint at an angle (alpha) determined from the formula:- where A is the amplitude of the transverse oscillations in mm of the beam, and f is the frequency of the oscillations. The angle (alpha) is the angle of the path taken by the oscillations w.r.t. the longitudinal direction of travel of the seam past the beam. In an example, steel was welded to bronze using an angle (alpha) of 66 deg. 22 minutes. The welds obtd. are hermetic and possess high strength.

Title: Bakery transfer mechanism to elongate or space dough pieces - wedged in base of vee section made in separable sections with pivoted sides
IPC: A21C11/00
Filed: 1982-03-26
Abstract: A transfer mechanism for elongating and/or spacing bakery dough pieces. The mechanism is to be installed between a dough piece forming band conveyor and a reception grill which feeds a proving chamber. The mechanism receives the dough piece(s) longitudinally in a 'V'-shaped channel of which the overall length is sub-divided into several sections. These sections are suspended at the top edges of the sides of the 'V' on pivotal axes along which the sides are longitudinally slidable. In operation the prod. is dropped into the base of the 'V' which is acute angled sufficiently to wedge the prod. The sections are then moved apart, e.q. by fluid power cylinder(s). This action elongates a dough piece already long enough to bridge two or more channel sections. Shorter dough pieces occupying a single section are spaced further apart. The sides of the 'V' are then pivoted above their top edges to open the bottom edges and drop out the prod. Used in bakery to elongate long dough pieces and to space out small dough pieces for mfg. bread rolls. The transfer mechanism replaces divergent conveyor bands employed for the same purpose. The divergent bands have proved troublesome in requiring constant attention to transverse positioning and tensioning of individual bands. B.
