pro Apparatus and method for improved recovery of latent fingerprints By www.freepatentsonline.com Published On :: Tue, 12 May 2015 08:00:00 EDT Hydrating an object bearing a latent fingerprint and then selectively drying the object leaving the fingerprint hydrated. The hydrated fingerprint is then coated with cyanoacrylate ester, preferably in a heat accelerated cyanoacrylate ester vacuum chamber. Hydrating is preferably accomplished by chilling the object below a dew point and then exposing the object to humidified air to condense a thin uniform layer of water over the object and latent fingerprint. Drying is preferably done with a vacuum. After drying reaches the preferred state, the CE is heated and coats the condensation-hydrated latent fingerprint. Preferably, the method is implemented in an automated system using one computer-controlled chamber for chilling, condensing, vacuum drying, and CE coating the latent fingerprint. The operator simply puts the object in the chamber, initiates the process by computer, and is prompted by the computer to remove the recovered latent print. Prints unrecoverable by prior art means are recovered. Full Article

pro Spinning machine and method for interrupting yarn production on a spinning machine By www.freepatentsonline.com Published On :: Tue, 30 Dec 2014 08:00:00 EST A method is provided for interrupting yarn production on a spinning machine upon detecting a defined deviation of a monitored yarn parameter from a target value, upon changing bobbins at a winding device, and/or prior to switching off the spinning machine. The feed speeds of the delivery device, the take-off device, and the winding device are gradually reduced to a stop in order to interrupt the yarn production, wherein the reducing takes place such that an end of the produced yarn is located within the spinning point after the reducing is completed.

pro Spinning machine and method for interrupting yarn production on a spinning machine By www.freepatentsonline.com Published On :: Tue, 13 Jan 2015 08:00:00 EST A method interrupts yarn production on a spinning machine having at least one spinning point having an inlet for a fiber material and an outlet for the yarn made from the fiber material, and wherein the spinning machine comprises a delivery device for feeding the fiber material into the spinning point, a take-off device for drawing off the yarn out of the spinning point, a winding device for winding up the produced yarn, and a yarn monitoring unit for monitoring at least one yarn parameter. Yarn production is interrupted upon detecting a defined deviation of the monitored yarn parameter from a target value, upon changing bobbins at the winding device, and/or prior to switching off the spinning machine. The feed speeds of the delivery device, the take-off device, and the winding device are gradually reduced to a stop in order to interrupt the yarn production, wherein the reducing takes place such that the end of the produced yarn is located between the outlet of the spinning point and the winding device after the reducing is completed.

The hybrid yarn includes a core substantially made of staple fibers aligned in a straight line in the longitudinal direction of the hybrid yarn, and a cover made substantially of staple fibers wound helically about the core. The staple fibers forming the core and the staple fibers forming the cover each are made of an intimate mixture of thermoplastic matrix fibers and reinforcing fibers. Full Article
pro Yarn-producing apparatus for an air spinning machine with an inset and a spinneret equipped therewith By www.freepatentsonline.com Published On :: Tue, 03 Mar 2015 08:00:00 EST A yarn-producing apparatus for an air spinning machine, which is used for producing a yarn from a fiber strand with the assistance of an air flow, has a spinning tip with an inlet opening surrounded by the outer surface of the spinning tip, in the area of which a yarn is able to be produced with the assistance of the air flow. The yarn-producing apparatus has an internal inset with a draw-off conduit adjacent to the inlet opening for the yarn and several air outlets branching off on the side from the draw-off conduit, such that an air flow introduced counter to the direction of spinning (S) in the draw-off conduit can escape in part through the air outlets and in part through the inlet opening. In addition, a spinning unit with a corresponding yarn-producing apparatus is provided. Full Article
pro Method for the production of a three-layer metal cord of the type that is rubberized in situ By www.freepatentsonline.com Published On :: Tue, 21 Apr 2015 08:00:00 EDT Method for manufacturing a metal cord with three concentric layers including a first layer of diameter dc made up of M wire(s) of diameter d1, around which layer are wound together as a helix at a pitch p2, as a second layer, N wires of diameter d2, around which are wound as a helix at pitch p3, as a third layer, P wires of diameter d3. The N wires of the second layer are assembled around the layer to form, at a point called “assembling point”, an intermediate cord called “core strand” of M+N construction; upstream and/or downstream of the assembling point, the layer and/or the core strand is sheathed with a rubber or rubber composition by passing through at least one extrusion head; then the P wires of the third layer are assembled around the core strand to form a cord of M+N+P construction thus rubberized from the inside.

pro Construction-equipment bucket-tooth assembly and bucket provided to same By www.freepatentsonline.com Published On :: Tue, 07 Apr 2015 08:00:00 EDT A bucket tooth assembly is mounted to an adapter provided to a distal end part of a bucket of construction equipment. The bucket assembly includes a bucket tooth and a latching member. The bucket tooth has a cavity for inserting the adapter and a through-hole that is provided to the side face and communicates through to the adapter when the bucket tooth has been mounted to the adapter. The through-hole has a center axis. The latching member is fitted inside the through-hole and having a rotational axis disposed along a direction of the center axis and a bottom part provided to an end on an adapter side in an axial direction. The latching member is rotated to switch between a first state in which the bottom part is held inside the through-hole and a second state in which the bottom part protrudes toward a concave portion on the adapter side.
