摘要： A steel barrel rotation assembly for rotating a steel barrel for manufacturing a steelpan drum includes a base that is positionable on a horizontal support surface, a plurality of legs extending upwardly from the base and a mounting disk attached to the plurality of legs. A rotation disk is rotatably disposed on the mounting disk and a steel barrel can be positioned on the rotation disk. A drive unit is coupled to the mounting disk and the drive unit mechanically engages the rotation disk. The drive unit rotates the rotation disk when the drive unit is turned on to rotate the steel barrel. A plurality of holders is each of the holders is slidably disposed on the rotation disk. Each of the holders extends upwardly from the rotation disk to engage the steel barrel for securing the steel barrel on the rotation disk.

摘要： A through-beam multi-digit dry meter is disclosed, wherein a lower and an upper holding plate are fastened together; two brackets are integrally connected on the lower holding plate. A 180° curved frame is between the brackets, on which is a flexible printed circuit. Engagement holes are in the brackets. A light-transmitting hollow character wheel shaft is in the engagement holes. Character wheels are on the light-transmitting hollow character wheel shaft and made of light-transmitting material. On the left and/or right side of a character wheel, short black strips are stamped. Long black strips are stamped on the character part of the character wheel head to tail, on which numbers are printed. The meter enables direct reading of three to eight character wheels to measure gas, electricity of water of large flow within the national standard limitation, which is easy to produce and assemble and saves the cost.

摘要： Direction of barometric pressure trend is portrayed by my invention. Changes in barometric pressure are amplified by a linkage member and converted into a signal by trend means to discern an increase or decrease in trend. Motor means receives the signal from trend means and activates display means to show the direction of barometric pressure trend.
