The washer-spacer may be fixed to the cam by adherence and to the shaft by cooperation of shapes due to complementary projections provided respectively on the shaft and on the washer-spacer.

Abstract: The inventive heald frame comprises two pillars (4), two cross bars (6) and fixing means which are used for fixing at least one pillar to at least one corresponding cross bar and which comprise a protrusion (41) of the pillar (4) to be received in a recess arranged in the cross bar (6). Said fixing means also comprises an intermediate tubular fixing element (14) which is disposed in a housing (12) embodied in the cross bar (6) and defines the internal volume (V) which forms said reception housing for at least one part of said protrusion (41). The inventive healed frame is also provided with common connection means between said intermediate element (14) and the cross bar (6).

Abstract: The dobby according to the invention comprises, at the level of each of its blades, an oscillating piece associated with an actuation element, at least one mobile coupling member borne by the actuation element and two pivoting levers subjected, on the one hand, to the action of a reading device and, on the other hand, to that of elastic means which tend to engage catches of the pivoting levers either with a jamming surface provided on the actuation element, or with the coupling member, while the lever in engagement with the jamming surface is out of range of a selector of the reading device. In addition, mechanical members independent of the reading device are adapted to displace, against the action of the elastic means, a lever whose catch is not in engagement with the jamming surface, with the result that it does not interfere with the angular displacement of the selector.

Abstract: A rotary dobby which includes pivoting arms which are moveable with respect to a plate connected to an element for actuating a heddle frame in controlled response to a reading-in device and wherein the pivot arms include catches which are uniquely configured having internal and external bearing surfaces which cooperatively engage binding surfaces of the plate.

Abstract: A rotary dobby which includes pivoting arms which are moveable with respect to a plate connected to an element for actuating a heddle frame in controlled response to a reading-in device and wherein the pivoting arms include catches which are engageable with respect to first and second spaced binding surfaces of the plate in such a manner that one of the arms is spaced from an actuator associated with the reading-in device when the pivoting arms are engaging the binding surfaces.

Abstract: An actuating selection device for a dobby mechanism for controlling movement of components used to affect movement of a heddle frame and a weaving loom wherein the selection device includes selector members which are pivotally mounted adjacent pole faces of an electromagnet and wherein a moveable armature is pivotally connected to the selector member and includes an outer extremity which is continuously urged into contact with a first of the poles of the electromagnet by a resilient element. The selector member is spaced from the electromagnet when no power is applied thereto and the selector member is moved toward the other pole of the electromagnet together with the moveable armature when power is supplied to the poles of the electromagnet with the movement of the selective member thus controlling the movement of the pair of components which affect the movement of the heddle frame.

Abstract: A shoe for protecting pulleys in a drawing system associated with a heddle frame of a weaving machine. The shoe has an inner portion of concave profile from which a projection extends so as to be receivable within a groove of the pulley. The shoe also includes two outer segments in one of which a groove is provided having a bottom which is oriented tangentially to the groove of the pulley so that the cable guided therein will be directed generally tangentially with respect to the groove of the pulley.

Abstract: In a weaving machine with a cam mechanism for forming the shed a heddle frame levelling apparatus includes rocking levers which are pivoted about a pin which is urged against a fixed bearing surface on the frame of the machine during weaving by elastically deformable elements. In a first embodiment the movement of the pivot pin is effected by the rotation of an eccentric bearing whereas in a second embodiment this movement is caused by a jack.

Abstract: In a dobby drawing device in a weaving loom, the vertical displacement of a heddle frame is obtained with the aid of a single cable which is guided over first and second actuating levers to a set of springs. Two support shafts selectively support the actuating levers so the device may have a lifting or descending action.

Abstract: An electrode balloon for use in anatomical cavities, such as cardiac chambers, to pick up bioelectrical signals from the walls thereof simultaneously in a multitude of sites for the mapping of the activation potentials thereof comprises an inflated tight rubber balloon having an opening at a proximal end thereof communicating with a filling tube which defines apertures for dispensing fluid in the rubber balloon. An extensible knitting which covers the rubber balloon is provided with a plurality of electrode heads distributed thereon to contact the walls of the cavity when the rubber balloon is inflated by a fluid conveyed therein through the tube. Insulated electrical conductors connect the electrodes to a signal recording and processing device.

Abstract: A double-lift dobby of the Hattersley type, which includes swinging levers carried by moveable connecting rods wherein each connecting rod includes a slot in which an idle roller secured to the dobby frame is engaged. The edges of each slot define opposite tracks which guide the trajectory of each connecting rod during its full stroke.

Abstract: In a weaving mechanism which includes rocking members for controlling the movement of heddle frames for forming the shed in weaving machines, the rocking members are separated from one another on a common support shaft by spacers interposed therebetween which spacer members are provided with projecting bosses which come into contact with bosses of adjacent spacer members. A rod cooperates with an arm of the spacers to insure the spacers are non-pivotably retained while the rocking members are moveable between the bosses extending therefrom.

Abstract: A water bottle tilting assembly mounted on a water dispensing cabinet is arranged to support the water bottle adjacent the dispensing cabinet at a level so that when the bottle is tilted about an axle the mouth of the bottle automatically reaches the trough of the cabinet with a breakable seal around the mouth of the bottle. A pointed sharp cutter is located inside the trough of the cabinet and breaks the seal when the bottle reaches its upside down position to allow the water to flow in the water dispensing cabinet.

Abstract: A modulator mechanism for actuating textile dobbies in looms which include a cage driven in rotation by the drive shaft of the loom and which have at least two oscillating supports provided with rollers which roll in contact with a fixed cam which is connected to the principal shaft of the dobby. Connecting rods are pivotally attached to the supports and to a web fixed to the dobby shaft so that the dobby shaft is intermittently driven in rotation as the connecting rods are oscillated by the supports.

Abstract: A double lift dobby for controlling the movement of the heddle frames of a weaving machine which includes coupling members pivotally connected at each end of double swinging levers which coupling elements are selectively engaged to oscillating plates by reading and transmission elements controlled by extendable members of an actuating mechanism.

Abstract: In negative dobbies of the type incorporating swinging lever assemblies to which lever elements are connected and which lever elements support two articulated hooks, retaining members are provided in the form of pivotable locks placed between the bearing face of each hook and the pivot pins by way of which the hooks are mounted to the lever elements.
