A device for control of the effects of vibrations on vibration sensitive equipment when a plurality of the devices are placed on a support surface and in operative contact with the vibration sensitive equipment where said device is a unitary piece of a soft, pliable substance having a hardened round crown portion.

A scooter is disclosed which positions a center of gravity of a rider toward the front the scooter so that the rider can more easily perform a 180 degree turn trick. Since the rider is positioned closer to the front wheel, it becomes easier for the rider to flip over the handlebars. Fortunately, the scooter reduces a moment arm that defines a deceleration moment to reduce the likelihood that the rider will flip over the front handlebars.

The invention relates to the technical field of numerical control machining, and discloses a bridge-type electrical discharge machining machine tool, which includes a bed, a workbench, an X-axis direction feed mechanism, a Y-axis direction feed mechanism, a Z-axis direction feed mechanism, and an oil tank. The body is equipped with a worktable installation base and two parallel Y-axis direction guide rails. The workbench installation base is located obliquely below the Y-axis direction guide rails, and the Y-axis direction feed mechanism is opposite to the two Y-axis direction guide rails. A Y-axis direction slide groove is provided, and the Y-axis direction feed mechanism is slidably installed on the Y-axis direction guide rail through the Y-axis direction slide groove. The feed mechanism of the electric discharge machining machine tool of the present invention is directly installed on the bed without the need for a column structure, which simplifies the structure and improves the stability of the structure; and the machine tool of the present invention is provided with two parallel Y-axis direction guide rails on the bed To install the feed mechanism in the Y-axis direction to form a bridge structure, which has a compact structure, small deformation, good precision retention, and can achieve high-precision movement.

A safety tool for opening a well lid comprises a base. An inclined telescopic support and a well lid fixing mechanism are arranged on the side of the base, and a well lid lifting mechanism is arranged on the side face of the telescopic support. The telescopic support comprises an upper support of a hollow structure and a lower support of a hollow structure. The upper portion of the lower support stretches into the upper support. A strip-shaped opening is formed in the side face of the upper support, and a vertical plate is arranged on the side face of the upper end of the lower support and arranged outside the strip-shaped opening. The well lid lifting mechanism comprises a first chain wheel and a second chain wheel. A chain is arranged on the first chain wheel and the second chain wheel and fixedly connected with the vertical plate. A rotary handle is arranged at the outer end of a first rotary shaft. A ratchet mechanism is arranged at the top of the upper support and comprises a ratchet fixed to the first rotary shaft, and a pawl matching the ratchet is arranged on the side face of the ratchet. The well lid fixing mechanism comprises a vertical rod. A cross rod is arranged at the lower end of the vertical rod, and a bearing is arranged at the upper end of the vertical rod and on the lower support. In the opening process of the well lid and after the well lid is opened, the well lid can be fixed conveniently, and the well lid is prevented from accidentally falling off.

A weight sorting mechanism with magneto-dynamic balance consists of bodyframe, balancing arm, at least one electromagnetic coil, mechanism for containing material and mechanism for fixing standard weight object. The mechanism for fixing standard weight objects is set at an end of the balancing arm.
