Systems and methods are provided for detecting potential failures in logging winch systems to enable efficient maintenance are provided. An example of such a system may include a logging winch system that conveys a downhole tool into a wellbore on a cable and a data processing system. The logging winch system may include sensors that measure observed quantities relating to operation of the logging winch system. The data processing system may determine correlation signatures that relate the observed quantities to the operation of the logging winch system and may identify when one or more of the correlation signatures indicates abnormal operation.

A device and a method for detecting a distance from a balloon to an ingot tank is provided. The device comprises a set of photoelectric transmitting tube and photoelectric receiving tube which are arranged in a height range of a balloon, Wherein a light beam between the photoelectric transmitting tube and the photoelectric receiving tube is arranged to be tangent to an appropriate balloon, and is used for detecting whether the balloon is located at an appropriate position according to a number of pulses received by the photoelectric receiving tube in one period of rotation of the balloon.

A method and associated method are provided or introducing a supply of reserve nose wires in a facemask production line prior to depletion of running nose wires in the production line. A first nose wire source and first cutter system are provided for supplying the running nose wires to the production line. A reserve nose wire source and second cutter system are staged in a stand-by state proximate to the first nose wire source. Prior to depletion of the first nose wire source, the reserve nose wire source and second cutter system are brought up to an operational speed while diverting nose wires from the second cutter system away from the production line. At operational speed of the reserve nose wire source and second cutter system, nose wires from the second cutter system are diverted to the production line while diverting nose wires from the first cutter system away from the production line.

A high efficiency bobbin winding device with adjustability has a housing that encloses at least one motor and associated circuitry and mechanism that allows a user to selectively wind a bobbin with a selected amount of thread. The motor is mounted on a hinged support that rotates to move the motor which has a shaft that spins the bobbin. An adjustment knob is rotated to selectively move the motor support. A sensor detects the amount of thread wound on the bobbin and stops further winding when the proper amount of thread is wound on the bobbin. The housing also has indicator lights to indicate power and other settings. A spool is placed on a rod and is thread through a guide and a tension adjustment and then on the bobbin where it is wound to a selected level.

A machine for coiling pipes (1) in spool form, includes a structure (10) supporting a rotating reel (11), a feeder unit for feeding a pipe (1) to the reel (11) in a longitudinal direction (X-X), a device (12) for cutting the pipe (1), a measuring unit (20) for measuring the length of the pipe (1), arranged upstream of the cutting device (12), in the longitudinal direction (X-X). The machine includes a device for hermetically sealing the pipe arranged in a zone of the machine situated upstream in the direction of feeding of the pipe towards the reel of the means for fastening to the reel and upstream of the cutting device in the same direction of feeding.
