A system for providing power to more than one ultrasonic welding probe from M power supplies includes N multipoint units and a base. Each of the N multipoint units includes: a housing, a plurality of analog or digital inputs configured to carry distance information regarding probe distance of a plurality of ultrasonic welding probes, a dedicated high voltage input connector connectable via a high voltage cable to a dedicated high voltage output connector of one of the M power supplies, and a microcontroller. The microcontroller is configured to: direct power from the dedicated high voltage input connector to a corresponding one of the plurality of ultrasonic welding probes, and sample the distance information of the plurality of ultrasonic welding probes at a rate of at least once per millisecond. The base houses the M power supplies, wherein M and N are both integers greater than or equal to 1.

In a production method of an elastic composite sheet, the elastic member does not break when the elastic member, in a stretched state, is bonded to a base material sheet; an elastic composite sheet and a disposable wearable article use the elastic composite sheet. A strip-shaped or string-shaped elastic member composed mainly of a thermoplastic elastic resin is stretched in the longitudinal direction of the elastic member. The stretched elastic member is placed over a first base material sheet such that the main surface of the first base material sheet contacts the elastic member. In this state, the elastic member and the first base material sheet are bonded in a first position that overlaps the elastic member seen from a direction perpendicular to the main surface of the first base material sheet and that is away from the edges of the elastic member.

A device for winding a reinforcing strip onto a repair length on either side of a portion to be repaired of a pipe, including: a carriage bearing a reel holder and a reel, means for rotating the carriage around the pipe and for translating same along the longitudinal axis of the pipe so that the strip is wound around the pipe in the form of a helix, means for reversing the direction of translation movement of the carriage so that, at each change of direction, the carriage moves in a direction opposite to the previous one and a layer of reinforcing strip is wound around the pipe, overlapping the previous layer. The means for translating the carriage include a conveying chain and the reversing means are actuated automatically without the intervention of an operator.

A lubricant/sealer dispenser is disclosed for a component press-in system that includes a pressurized lubricant/sealer reservoir filled with lubricant/sealer. A nozzle is supplied with lubricant/sealer from the reservoir and includes an offset tip formed of PTFE that is enclosed in a steel tube. A controller controls a motor that rotates the nozzle within an opening in a part at a selected depth. The motor rotates the nozzle about a fixed axis and follows an inner surface of the opening as the part is moved by a robot relative to the nozzle in a selected pattern. The nozzle applies the lubricant/sealer by applying the lubricant/sealer onto the inner surface of the opening.

A machine configured to repair a pipeline extending along a longitudinal axis determined in a body of water, the machine comprising: a frame configured to be clamped to the pipeline; an applicator configured to apply material along an outer surface of the pipeline and comprising a support body shaped as an open ring and configured to be arranged about the pipeline; and an actuating assembly, which is supported by the frame, is arranged between the frame and the applicator, has a distal end configured to support the applicator in a cantilevered fashion and in a rotatable manner, and is configured to displace the applicator along the longitudinal axis and/or to rotate the applicator about the longitudinal axis.

A gasket welding apparatus (10) comprising: a pair of opposed clamping members (16A, 16B) for supporting corresponding first and second lengths of gasket material. The clamping members (16A, 16B) being moveable towards and away from one another by an actuator (58). The gasket welding apparatus (10) comprises a heating element (30), the heating element (30) is moveable between a first position in which it is removed from the clamping members and a second position in which it is disposed between the clamping members.

The present invention discloses a heat fusing device for a smart trash receptacle, including: a heating wire for fusion-cutting and thermally sealing an open end of a trash bag, the heating wire being connected to a heat-fusing circuit; a base having heat-resistant and insulating properties, the base having a first end surface on which the heating wire is arranged; and a control mechanism communicatively coupled to the heat-fusing circuit for control thereof. The present invention also discloses a smart trash receptacle incorporating the heat fusing device and a method for controlling a heat fusing temperature. With the present invention, during automatic bagging by the smart trash receptacle, good contact between the heating wire and the trash bag can be ensured while preventing adhesion of the trash bag. This results in improved sealing quality and enables the fulfillment of two tasks, i.e., thermoplastic sealing and thermal fusion-cutting, in the same action of the heat fusing device. As a result, higher automatic bagging quality and reliability are obtainable at lower bagging control difficulty and reduced bagging cost. Moreover, control in the system is simplified, and the stability and reliability of the system are increased.
