Abstract: An adjusting base for door closer includes a fixing member, an adjusting member, and at least one adjusting unit. The fixing member is configured to be fixed to a surface, and an upper surface of the fixing member is arranged with at least one protrusion. The adjusting member is arranged on the upper surface of the fixing member in an adjustable manner, and configured to be connected to a door closer. The adjusting member is formed with at least one adjusting hole for receiving the at least one protrusion. The at least one adjusting unit is movably arranged on the adjusting member and configured to abut against the at least one protrusion to adjust a relative position between the adjusting member and the fixing member.

Abstract: A color masterbatch composition, comprising a thermoplastic polyester, a yellow colorant component, a red colorant component, and a blue colorant component. The yellow colorant component is selected from Pigment Yellow 147, Pigment Yellow 181, Pigment Yellow 183, Dye Brown 53, or a combination thereof. The red colorant component is selected from Pigment Red 122, Pigment Red 144, Pigment Red 202, Pigment Red 214, or combination thereof. The blue colorant component is selected from Pigment Blue 60, Dye Blue 67, or a combination thereof. The present invention further provides a colloidal particle that is obtained by developing the above masterbatch composition in a base material mainly composed of thermoplastic polyester. An article produced from the present disclosure has an effect of slowing down and reducing heat absorption and can maintain its original color during processing.

Abstract: A door closer device for driving a door to a predetermined closed position includes an adjustment mechanism and a door closer which is integrated with the door. The adjustment mechanism includes a base, an adjusting plate and at least one fixing element, wherein the adjusting plate is stacked with the base and coupled with the door closer. The adjusting plate and the base respectively include at least one adjusting bore, and the adjusting bores are corresponding with each other. One of the adjusting bores includes a first limiting end and a second limiting end, and a first moving path is defined between the first and second limiting ends. The fixing element is disposed in the adjusting bores and can move along the first moving path to fix the adjusting plate on the base.

Abstract: A door closer pivoted on a door at least includes a case and a piston. When the door is open, the door closer blocks a communicating hole of the case by an oil sealing ring of the piston to allow an oil filled in the door closer cannot flow through the communicating hole. As a result, the open door can be held in a predetermined position.

Abstract: An alarm device is designed to warn of danger of hitting high voltage overhead power lines by a crane in motion. The alarm device is composed of an electric-field sensor for detecting the alternating electric field of the overhead power lines and for outputting an alternating current, which is then converted or amplified by an amplifier connected with the electric-field sensor. An alternating voltage is outputted by the amplifier such that the alternating voltage is rectified and filtered by a rectifier/filter circuit connected with the amplifier. A direct current voltage output is brought about by the rectifier/filter circuit. A starter is disposed between the rectifier/filter circuit and a wireless transmitter capable of being activated by the starter to transmit a wireless signal at such time when the value of the direct current voltage exceeds a preset value. The alarm device is further composed of a wireless receiver/alarm for receiving the wireless signal and for effecting a warning signal.
