Abstract:
Placement of nanofibers and yarns comprised of nanofibers onto a substrate are described. The nanofiber yarns are difficult to manipulate with precision given that the diameters can be as little as 5 microns or even less than one micron. As described herein, a placement system is described that can place nanofiber yarns on a substrate at pitches less than 100 µm, less than 50 µm, less than 10 µm, and in some embodiments as low as 2 µm. In part, this precise placement at small pitches is facilitated by the use of coarse and fine adjustment translators, and a guide connected to a compliant flange. The compliant flange and the guide facilitate consistency of location of a nanofiber yarn.

The present invention relates to a retracting device (6), vehicle provided therewith and method for retracting a hose. The retracting device (6) comprises: - a frame (46); - a retraction drive (22), connected to the frame (46), for retracting the hose; - a coupling (62) configured to couple the frame (46) to a container (8), and a displacement drive configured to displace the frame (46) relative to the container (8) such that the retracted hose can be placed in the container (8); and - a hose guide (50) configured to guide the hose for retraction to the retraction drive (22), wherein the hose guide (50) is displaceable in operative connection to the frame (46).
Abstract:
A ligature attachment device for use with a ligature is disclosed, the ligature attachment device comprising a proximal section comprising a loop retainer section, a distal section comprising a tool section, a central section comprising a central ligature spool section having a centrally located cinch aperture and the central ligature spool section is coupled to the loop retainer section and the tool section. The loop retainer section having a loop retainer profile configured to retain a loop of the ligature frictionally engaged with the central ligature spool section. The cinch aperture having an aperture shape configured to allow at least two sections of a ligature to be removably retained in the cinch aperture whereby the cinch aperture can removably retain the loop of the ligature. The tool section comprises a first tool for removably joining a second tool.
Abstract:
The present invention relates to an apparatus and to a method for grouping a plurality of supply means, such as optical fibres, electrical cables, telephone wires, antenna cables, water conduits, drain pipes, sewers or any other flexible supply means, in an effective and flexible manner. The present invention further relates to a method for grouping a plurality of supply means.
Abstract:
A method of winding a fibrous strand (14) includes mounting a first collet (22a) and a second collet (22b) on a rotatable turret (64), and rotating the first collet to wind the strand using a cam (30) to build a first package (20). The stand is transferred from the first collet to the second collet to build a second package on the second collet, and the turret is rotated while transferring the strand from the first collet to the second collet.
Abstract:
The invention relates to a strand (68), a woven fabric (78), a yarn package (19), a method of collecting a strand, and a method of inserting a fill yarn in an air jet loom.
Abstract:
A wick dispenser for holding a wick material includes a housing defining a chamber and a wick outlet. The wick dispenser further includes a spool positioned within the chamber of the housing and configured to support the wick material. The spool is rotatable relative to the housing about a rotational axis. The wick dispenser further includes a handle coupled to the spool and accessible for manual rotation by a user. Rotation of the handle results in rotation of the spool. Rotation of the handle in a first direction unravels the wick material from the spool. Rotation of the handle in a second direction draws the wick material into the chamber through the wick outlet.
Abstract:
Máquina de desenrollado y enrollado de hilo a una velocidad superior a1m/s y sin torsión que comprende; un medio de entrega de hilo giratorio que comprende una bobina de entrega de hilo y un motor (M1), un medio de recogida de hilo giratorio que comprende, una bobina de recogida de hilo, unos medios de vaivén que definen la geometría de la bobina, y un motor (M2), donde al menos el medio de entrega de hilo o el medio de recogida de hilo comprende de un medio limitador de par con un valor de limitación del par (Zmax) y provocando siempre una velocidad de deslizamiento (Vdes), entendida como la diferencia de velocidad angular la velocidad angular del eje del motor asociado al medio limitador de par y la velocidad angular de la bobina asociada al medio limitador de par, de tal manera que es posible establecer la tensión del hilo (Twork) medida entre los medios de vaivén y la bobina de recogida durante el proceso de transformación y consecuentemente poder mantener dicha tensión del hilo (Twork) por debajo de una tensión máxima (tmax) y por encima de una tensión mínima (tmin) modificando solo la velocidad de deslizamiento (Vdes).
Abstract:
A guard insert having a body and a guide. The body can include a top surface, an opposed bottom surface, and a plurality of side edges extending between the top and bottom surfaces and including a front side edge. The body can define a slot and a plurality of fastener-receiving openings. The slot can extend inwardly from the front side edge. The plurality of fastener-receiving openings can extend through the top and bottom surfaces, with each opening of the plurality of fastener-receiving openings being configured to receive a fastener. The guide can be securely received within the slot of the body. The guide can have an outer peripheral wall and an inner peripheral wall. The outer peripheral wall can have a shape complementary to the slot, and at least a portion of the inner peripheral wall can define a channel configured for receiving yarn.
