Patent number: 5879455Abstract: In the case of a paraffin waxing device for a travelling yarn, a rotating paraffin body is weighted in axial direction against a stopping face. The stopping face lies against the front surface of the paraffin body, over which the travelling yarn is guided. During the waxing process, undesired rubbing off of paraffin particles can soil the feed material or the machine elements. According to the invention, the stopping face is rolled on the rotating front surface. The rubbing-off of paraffin particles, in particular in the area of the stopping face, is hereby avoided.Type: GrantFiled: October 3, 1996Date of Patent: March 9, 1999Assignees: Fritz Stahlecker, Hans StahleckerInventor: Fritz Stahlecker

Patent number: 5431953Abstract: A length of conductive wire is supported between a first reel and a second reel. The first reel is driven to move the wire through the device in a stepped fashion. Each time the wire stops a reciprocating plunger brings a material to be evaporated into contact with the wire. An electric current is passed through the length of wire in the area where the material contacts the wire. The wire is heated by the electric current to melt the material onto the wire to form a bead of material thereon. The wire is advanced to repeat the bead forming process. The wire with the beads formed thereon is wound onto the first reel for later use in an evaporator process. An infrared sensor monitors the heating process to determine if the material is melted at the desired temperature. A sensor is also provided to stop the device if the wire breaks. The advancing of the wire, the operation and refilling of the plunger and the heating of the wire are all performed automatically.Type: GrantFiled: May 12, 1992Date of Patent: July 11, 1995Assignee: Hamamatsu CorporationInventor: Norman Lyshkow

Patent number: 5362326Abstract: Disclosed is a method of forming corrosion protection coatings on prestressing strands. It comprises the steps of untwisting sequential lengths of a prestressing strand; keeping the surrounding steel wires apart from the core steel wire to coat these steel wires with a synthetic resin; and twisting the coated steel wires to provide a prestressing strand of the original shape, thus permitting the separate coating of each steel wire, leaving, on the prestressing strand surface, the helical dent as deep and wide as the noncoated prestressing strand to assure the bond of the twisted wire to the surrounding concrete as firm as the noncoated prestressing strand. Also, an apparatus for carrying out such coating method is disclosed.Type: GrantFiled: April 14, 1993Date of Patent: November 8, 1994Assignee: Kurosawa Construction Co., Ltd.Inventors: Takeshi Hasui, Takatsugu Fujikawa

Patent number: 5282377Abstract: When drawing wire, and particularly wire of highly tenacious material which s difficult to deform, such as tungsten or molybdenum, through a die (4), lubricant is applied to the surface of the wire (1) by generating a curtain or sheet of lubricant (6, 16) emitted from a slit-like nozzle (14), and passing the wire essentially transversely through said curtain or sheet of liquid lubricant. Preferably, the wire is preheated before being passed through said sheet of lubricant so that the lubricant will dry on the preheated wire from the inside out prior to the wire being heated to optimum drawing temperature in advance of being pulled through the die. Suitable preheating temperatures are from 100.degree. C. to 500.degree. C., and the thickness of the curtain of lubricant can be between 0.05 to about 0.3 mm, with a wire thickness in the order of about 0.1 mm, permitting drawing speeds which can vary widely and can be about double of previously obtainable drawing speeds.Type: GrantFiled: June 16, 1992Date of Patent: February 1, 1994Assignee: Patent-Treuhand-Gesellschaft Fuer Elektrische Gluehlampen mbHInventors: Dietmar Illig, Oliver Eierle

Patent number: 5024864Abstract: Methods and apparatus are provided for applying a colorant material to the surface of a plastic insulation material which has been applied to an elongated material such as a metallic conductor (22) or an optical fiber which is being moved at any of a wide range of speeds along a path of travel. The coolant material is applied by nozzles which are staggered along the path of travel and which direct the colorant into engagement with the plastic insulation material at different radial directions. A first plurality of nozzles (46--46) each cause the colorant to be in a spray pattern (45) which is in the area of a plane. Advantageously, those nozzles cooperate to stabilize the conductor and prevent undulations thereof as the conductor is moved along its path of travel. A second plurality of nozzles (50--50) cause the colorant to be in a solid conical pattern (53).Type: GrantFiled: October 30, 1989Date of Patent: June 18, 1991Assignee: AT&T Bell LaboratoriesInventors: Larry L.

Patent number: 4068615Abstract: A control is provided for a wire coating line which includes means for driving wire along a path at controllable speed while coating it with plastic extruded at a controlled rate and temperature, and cooling means are located at a controllable distance from the coating means to solidify the plastic. The controllable factors affect both the capacitance and diameter of the wire produced. The control allows the line to be run in accord with stored digital values for the matters to be controlled. Closed loop control is provided because the relevant factors of line operation are measured, the analogue measurements converted to digital values and compared with the stored values to produce a control signal which has the effect of reducing the differences between a desired and measured line condition as represented by the digital values compared. Closed loop control is also provided for control of the line to produce desired capacitance or diameter values in the coated wire.Type: GrantFiled: November 10, 1976Date of Patent: January 17, 1978Assignee: Northern Telecom LimitedInventor: Victor Louis LeNir
