The quantity of material remaining in a 3D printing system may be effectively measured through the use of a strain gauge. The strain gauge may be mounted on a support member such as a cantilevered support that holds the weight of a material dispenser. As the material is consumed, the strain gauge may measure the reduction in deformation of the cantilevered support, thereby indicating to a control system and/or a user the quantity of material used. Full and/or empty material dispenser measurements may be taken to provide reference points that indicate how close the material dispenser is to being full and/or empty. The material dispenser may be mounted in a variety of locations relative to the 3D printer, including on a side and on top. A top-mounted material dispenser may be received within a bearing that permits the material dispenser to rotate, allowing the material to unwind during consumption.

The turntable on which the silver can is mounted is connected to a piston of a compressed air cylinder and air pressure is used to maintain the piston and table in preset positions. When the silver can is filled to the preset weight, the table and piston move downwardly to activate either a switch in the path of the piston or a pressure responsive switch in the air line to the pressure side of the air cylinder.

The present invention relates to a machine for tucking, labelling and palletizing spools at the outlet of winders or other machines producing spools of threads and the process practiced by this machine. Machine characterized in that it is essentially constituted by a station (2) for positioning spools (3) at the outlet of a winder (1) or other machine producing spools and cutting the tag end of the thread, by a robot (4) or the like for grasping the spool (3), for supplying a turning plate (5) and for unmounting the spools from said turning plate (5) and palletizing them, by a device (6) for grasping, positioning, holding and cutting the length of the tag end of thread, by a means (7) for needle tucking, or the like, and by a labelling station (8), all of these stations and devices being controlled by means of a computer control means. The invention is more particularly applicable to the textile industry, in particular for handling spools of threads.

Method for on-line process control of yarns wound upon reels intended for yarn package classification and sorting into homogeneous classes of predetermined quality standards. This method consists in the determination of the specific weight of the yarn bundling on the reel. This value is utilized to check the yarn package compliance with preset standard values of the technological properties, in particular of the dyeing affinity.

An improved fiber glass bushing control system. One aspect of the system has a weighing means for weighing complete collections of glass fiber strands produced from forming from a bushing through attenuation, a monitoring means for the time of attenuation at constant strand speed and a program computer means that receives signals from the weighing means and the monitoring means. The program computer means has a means for establishing a database of the weights and times, a means for determining the throughput of the glass from the bushing from the weights and times, a means for determining average throughputs and including these averages in the database, a means for comparing the average throughputs to a standard set throughput, and a means for initiating an adjustment to the main bushing temperature controller, when the average throughput deviates from the set point throughput by a value greater than the sensitivity factor of the bushing. The system has circuit means for carrying the adjustment signals to the controller and to the bushing for a temperature change. The system can have a second bushing controller connected across two sections of the bushing to regulate relative current flow in the two sections and the program computer means additionaly has means for determining the difference in throughputs between collections of strand produced from each section of the bushing at the same time and placing these difference values in the database, and a means for averaging the difference values, and a means for comparing the difference values to determine if they are other than the value of zero, and a means for adjusting the segment bushing controller to achieve average difference value in throughput other than zero.

Systems and methods for determining that a consumable welding package has been, or may have been, replenished in a high production welding environment and that a tracked weight value of the consumable welding package should be reset. An operator of a welding system can be notified that a consumable welding package may have been replenished and, therefore, that the weight value of the consumable welding package may need to be reset in the welding system. Alternatively, the weight value of the consumable welding package in the welding system may be automatically reset when the welding system has determined that the consumable welding package has been replenished.
