Abstract: A member for guiding harness cords of a Jacquard loom harness wherein the member is substantially planar and is provided with holes defining passages for the cords. At least one of these passages extends in a direction that is oblique with respect to a principal plane of the member. This arrangement makes it possible to reduce frictional forces undergone by the harness cords, particularly at the upper and lower edges of the holes.

Abstract: The heddle according to the invention is provided at the level of each of its ends with at least two sections for simultaneous bearing on corresponding surfaces formed on a traction bar fast with a crossbeam of a heddle frame. These sections and surfaces allow the transmission of an effort of traction exerted by one of the crossbeams on the heddle. They are offset in a direction substantially parallel to a longitudinal axis of the heddle and to an axis of the uprights of the frame.

Abstract: This member for guiding the harness cords of a Jacquard loom harness is substantially planar and provided with holes for passage of the cords. At least one of these holes extends in a direction which is oblique with respect to the principal plane of this member. This arrangement makes it possible to limit the efforts of friction undergone by the harness cords, particularly at the level of the edges of the holes.

Abstract: The frame, which is obtained by assembling two struts (21) with two cross-bars (22) each of which is provided with a heald-carrier rod (29), comprises at least one hoop (40) surrounding a tubular extremity (28) of said cross-bar (22) in an area in which it is joined to the adjacent strut (21) and an area in which at least one locking member (25, 26) of part (21a) of said strut is received. The area of junction is created in part (35) of the extremity (28) provided with an external transverse profile which is essentially convex. The hoop is provided in order to resist a locking effort (F3, F?3) exerted by the locking member (23, 24).

Abstract: A quick connect coupling for removably connecting two pipes which comprises a male element adapted to fit into a female element along a principal axis of the coupling. The Female element includes at least one ramp for receiving a radial projection of the male element to lock these elements together. The ramp is formed in a ring freely rotatably mounted in the female element, and fixed in translation along the principal axis, while the projection is fixed with respect to the male element. The ramp forms a seat for locking the radial projection. Locking is obtained by essentially axial movements of the male and female elements with respect to one another.

Abstract: Linearly actuated quick connect pipe couplings which include a male element and a female element adapted to fit into each other along a principal axis. One of the elements includes at least one ramp for receiving a radial projection mounted to the other element which locks the elements together by axial movement of the elements relative to one another. One of the ramp or the projection is formed with a ring mounted to rotate but is fixed in translation along the principal axis of one of the male or female elements. The ramp forms a first seat for locking the projection when the coupling is in a configuration to permit fluid passage and a second seat, offset axially with respect to the first seat, for locking the projection when the coupling is in a configuration to permit decompression of fluid within the coupling.

Abstract: The frame according to the invention comprises two uprights and two crossbeams, each of which is provided with a catching member adapted to receive a corresponding end of at least one heddle, while there are also provided damping means, fast with at least one corresponding catching member, which are placed opposite surfaces for direct abutment of this catching member against a corresponding heddle. The or each catching member is formed by at least one beat metal sheet, which ensures fixation of the damping means by cooperation of shapes and/or by adhesion.

Abstract: A device for positioning warp yarns of a weaving loom which are controlled by electrical actuators for forming a shed which includes a first detector common to the warp yarns driven by a plurality of different actuators for detecting the passage of at least one warp yarn into a predetermined position, and a second device for determining a value of a control parameter of an actuator for controlling movement of the at least one warp yarn upon passage into the predetermined position. The process consists in displacing a warp yarn and detecting its passage into a predetermined position and selecting a value of a control parameter of an actuator for the warp yarn upon passage of the warp yarn into the predetermined position and in using the selected value as a control point for controlling an actuator for the warp yarn.
