Abstract: Apparatuses and methods for applying laser energy for therapeutic purposes (e.g., relief of pain and/or inflammation in tissues) are disclosed. The synchronization of two spatially overlapping energy forms having closely positioned emission axes and particular emission modalities can in many cases provide strengthened or even synergistic effects in the alleviation or treatment of multiple of acute and/or chronic conditions (e.g., pain and inflammation) afflicting a given tissue. The laser energy forms are characterized in terms of their power levels, activation times, activation periods, pulse durations, pulse periods, wavelengths, and other identified characteristics.

Abstract: The invention relates to a process for piecing on a machine for producing core spun yarns, said process comprising the following successive steps of: taking off a broken end of a core spun yarn formed from the receiving member, (for example a reel); exposing the internal core of said yarn over a pre-determined length; connecting the core thus exposed with the end of the elementary core yarn; introducing the bared core into the fiber distribution system; distributing the fibers on the core downstream of the point of join; and advancing and winding normally. The invention also relates to a device for carrying out this process.

Abstract: A method of obtaining a core-spun yarn, according to which the fibers are subjected to a momentary false twist, and elementary fibers are projected on the spun yarn in the upwardly twisting area by means of a movable surface. According to the invention, all of the fibers (core and sheath) are subjected to the action of a common drawing system. After drawing, part of the fibers are delivered to the guiding surface to form the sheath while the other part of the fibers, which will form the core, is moved away from said surface and returned in contact therewith downstream of the zone in which the first part of the fibers are delivered. It is possible with this method to obtain, from only one supply, a variety of yarns of which the core and sheath can be composed of fibers of the same or of a different nature.

Abstract: The invention relates to a machine for producing a cabled yarn from two strands supplied from different supply sources. The two strands are twisted together over a freely rotatable roller disposed on the same axis as the upper bobbin, and the yarns which have been joined on the doubling roller, are subjected before winding, to the action of a compensating system which absorbs variations of tension and is adapted to actuate means for stopping the machine if one of the strands should break.

Abstract: Method for producing a fiber spun yarn of the type in which parallelized elementary fibers are joined to a textile core, subjected to a false twist, said fibers being projected on the core, upstream of the false twist spindle.According to the invention, in the fibers projection zone, the core is guided into a channel with an open face which is situated in facing relation to the elementary fibers projection zone and the surface of which is subjected to a flow of fluid tending to exert a pulling force on the end of the fibers.

Abstract: The invention relates to a process and device for making a spun yarn of fibres comprising an internal core which consists in subjecting the yarn to form the core to a momentary false twist by means of a spindle and projecting elementary fibres onto this yarn. Such elementary fibres are projected by means of a mobile guide surface on which the fibres are delivered tangentially, the core likewise being displaced tangentially with respect to the guide surface in a direction concurrent with the direction of delivery of the fibres.

Abstract: A device for stretching a rove of fibers during a spinning operation to permit forming the rove into spun yarn, the device comprising a condenser element placed after the actual stretching system.According to the invention, the condensing element is in the form of a movable guiding surface on which the fibers are delivered tangentially, the guiding surface pulling permits a force to be exerted on the end of the fibers coming out of the stretching system and limits the twist run back communicated by the spinning system.

Abstract: The present invention relates to a process for making a core spun yarn, wherein elementary fibres are projected onto a yarn, the yarn being subjected to the action of a false twist spindle. The projection of the fibres is obtained by means of a mobile guiding surface on which the fibres are delivered tangentially and are maintained paralleled and flat. Furthermore, the core is delivered tangentially on the paralleled fibres obliquely and in the direction of displacement of said fibres. The invention also relates to a device for carrying out this process.

Abstract: A process for producing a yarn with alternate twist, which is obtained by intermittently varying the distance which the twist extends back upstream of a false twister. The variation in the distance is produced without braking the yarn and is achieved by means of a blocking device acting intermittently at a point located close to the false twister. The duration of action of the blocking device approximately corresponds to the time taken by a given point on the yarn to cover the distance from a delivery member to the false twister.

Abstract: An apparatus is disclosed for the variable speed control of cams in a textile machine to provide for high speed winding of thread on spools which are controlled by the cams. A motor drives each cam. The speed of each motor is varied according to a predetermined cycle to produce a staggering of the thread on the spools from one layer to the other and to avoid the formation of bunches on the formed winding. The motors have a common induction supply which establishes the motors average speed and which operates to exchange the braking energy of the motors The driving energy applied to the motors is modulated in opposite phase in order to achieve variations around the average speed of the motors by inductively varying the flux of the motor windings.
