Abstract
Abstract An apparatus for detecting an enlarged section of a continuously moving elongated material. The apparatus includes a sensor member, a flapper member, a spring, and a fluidic coupling device. The sensor member has an open ended slot therein dimensioned to allow all of the elongated material to pass therethrough except for the enlarged section to be detected. One end of the sensor member has a relatively larger opening which is contiguous with one end of the slot for allowing the enlarged section of the elongated material to pass through the larger opening. The spring biases the sensor member in a direction opposite the direction of movement of the elongated material. The fluidic coupling device has an input port for receiving a fluid jet, a first output port adjacent to the flapper member, and a second output port for coupling a portion of the fluid jet to a monitoring device, which portion is inversely proportional to the remainder of the fluid jet exiting the first output port. Means is also provided for mounting the sensor member to pivotally move when the sensor member is contacted by the enlarged section of the elongated material which is not passable through the slot. The flapper member is mechanically coupled to the sensor member, and moves, in response to movement of the sensor member, away from the first output port, whereby the pressure of the fluid jet at the second output port decreases sufficiently to cause actuation of the monitoring device as the enlarged section of the elongated material moves through the larger opening adjacent the slot in the sensor member.

Claim 1
Independent Claim
372 words
An apparatus for detecting an enlarged section of a continuously moving elongated material comprising: a. a sensor member having an open ended slot dimensioned to allow all of the elongated material to pass therethrough except for the enlarged section, one end of said sensor member having a relatively larger opening therein contiguous with the open end of the slot for allowing the enlarged section of the elongated material to pass therethrough and out of the slot; b. a flapper member mechanically coupled to said sensor member and movable in response to movement of said sensor member; c. means for biasing said sensor member in a direction opposite to the direction of movement of the elongated material; d. a fluidic coupling device having an input port for receiving a fluid jet, a first output port adjacent said flapper member, and a second output port for coupling a portion of the fluid jet to a monitoring device in inverse proportion to the remainder of the fluid jet exiting the first output port; and e. means for mounting said sensor member to pivotally move when said sensor member is contacted by the enlarged section of the elongated material which is not passable through said slot and until the enlarged section can pass through the enlarged opening in said one end of said sensor member, said mounting means comprising: i. a dowel; ii. a coupLing member mechanically connected to said sensor member and said flapper member, and having a channel therein for receiving a portion of said dowel as opposite ends of said dowel extend from opposite respective ends of said channel; and iii. means for receiving said opposite ends of and supporting said dowel, whereby said sensor and flapper memebers are pivotally movable about said dowel and said coupling member, and said flapper member moves, simultaneously with said sensor member, with respect to the first output port of said fluidic coupling device, thereby causing a change in pressure at the first and second respective output ports, the change in pressure at the second output port being sufficient to cause actuation of the monitoring device as the enlarged section of the elongated material moves through the enlarged opening in said one end of said sensor member.
Claim 2

An apparatus for detecting an enlarged section of a continuously moving elongated material comprising: a. a sensor member having an open ended slot dimensioned to allow all of the elongated material to pass therethrough except for the enlarged section, one end of said sensor member having a relatively larger opening therein contiguous with the open end of the slot for allowing the enlarged section of the elongated material to pass therethrough and out of the slot; b. a flapper member mechanically coupled to said sensor member and movable in response to movement of said sensor member; c. means for biasing said sensor member in a direction opposite to the direction of movement of the elongated material; d. a fluidic coupling device having an input port for receiving a fluid jet, a first output port adjacent said flapper member, and a second output port for coupling a portion of the fluid jet to a monitoring device in inverse proportion to the remainder of the fluid jet exiting the first output port; and e. means for mounting said sensor member to pivotally move when said sensor member is contacted by the enlarged section of the elongated material which is not passable through said slot and until the enlarged section can pass through the enlarged opening in said one end of said sensor member, said mounting means comprising: i. a dowel; ii. a coupLing member mechanically connected to said sensor member and said flapper member, and having a channel therein for receiving a portion of said dowel as opposite ends of said dowel extend from opposite respective ends of said channel; and iii. means for receiving said opposite ends of and supporting said dowel, whereby said sensor and flapper memebers are pivotally movable about said dowel and said coupling member, and said flapper member moves, simultaneously with said sensor member, with respect to the first output port of said fluidic coupling device, thereby causing a change in pressure at the first and second respective output ports, the change in pressure at the second output port being sufficient to cause actuation of the monitoring device as the enlarged section of the elongated material moves through the enlarged opening in said one end of said sensor member.
Claim 3
Dependent Claim
35 words
An apparatus for detecting an enlarged section of a continuously moving elongated material according to claim 1, wherein said sensor member and said flapper member are integrally formed with and extend from said coupling member.
Claim 4
Dependent Claim
65 words
An apparatus for detecting an enlarged section of a continuously moving elongated material according to claim 1, wherein said biasing means is comprised of a spring having one end anchored between said mounting frame and said bracket, and said spring having another end attached to said sensor member to bias said sensor member in the direction opposite the direction of movement of the elongated material.
Claim 5
Dependent Claim
115 words
An apparatus for detecting an enlarged section of a continuously moving elongated material according to claim 1, wherein said flapper member presses against and blocks the first output port of said fluidic coupling device while the elongated material is moving through the slot in said sensor member, whereby the fluid jet exiting the second output port of said fluidic coupling device is at a maximum pressure, and when an enlarged section of the elongated material contacts the slot in said sensor member, said flapper member moves away from and unblocks the first output port to cause a decrease in the pressure of the fluid jet exiting the second output port of said fluidic coupling device.
Claim 6
Dependent Claim
26 words
An apparatus for detecting an enlarged section of a continuously moving elongated material according to claim 1, wherein said channel of said coupling member is C-shaped.
Claim 7
Dependent Claim
52 words
An apparatus for detecting an enlarged section of a continuously moving elongated material according to claim 1, wherein said receiving and supporting means is comprised of: a. a mounting frame; and b. a bracket affixed to said mounting frame, said bracket having holes therein for receiving said opposite ends of said dowel.
