Abstract: A method and the apparatus for implementing the method to provide temporary ground support in a mine. After an auger or other type of hole has been bored in an underground mine, at least one inflatable bladder with a fluid conduit therethrough is inserted into the hole. Once the bladder is inflated it expands to fill the hole's diameter and to act as a plug. Thereafter, fluid is forced through the fluid conduit past the bladder and into the hole cavity to act in conjunction with the bladder as a ground support for the hole. Appropriate fluid valves, meters, and conduits are placed at the input to the fluid conduit to control and measure the fluid being forced into the bladder and the hole cavity. Quick connect-disconnect couplings are provided when two or more bladders are connected seriatim and placed within the hole.

Abstract: A square hole drill having a cutterhead configuration whose outline is in the form of a Reuleaux triangle and which also has a planetary gear drive. Two counter revolving motions are present in the drill at the same time. One is the pure rotary motion of the drill's cutterhead about its own shaft. The other is the circular motion of the cutterhead as a unit about a center line due to its eccentric mounting and drive. To achieve the opposite rotation of the unit as a whole compared to the rotation of the cutterhead about its own axis, a combined meshing planet gear and ring gear are used. The planet gear is directly connected to the cutterhead by a shaft rigidly attached to the gear's front side. At the rear side of the planet gear is the eccentrically mounted drive shaft. Surrounding the external teeth of the planet gear is a larger stationary ring gear with internal teeth to continuously engage the planet gear's teeth. As these teeth become engaged the planet gear rotates on its own shaft and also rotates, in a larger radius, counter to that direction around the ring gear. In the preferred embodiment the rotation about the planet gear's shaft was one third as fast as the planet gear's rotation around the ring gear. The composite effect of these two counter revolutions when considered with the shape of the cutterhead is that the cutting bits transcribe and cut out a square hole.

Abstract translation: 具有刀头构型的方孔钻具，其轮廓呈Reuleaux三角形的形式，并且还具有行星齿轮传动。 两个反转运动同时存在于钻机中。 一个是钻头刀头围绕其自身轴的纯旋转运动。 另一种是由于其偏心安装和驱动，刀架作为中心线的单元的圆周运动。 为了相对于刀盘围绕其自身轴线的旋转而实现整体的相反旋转，使用组合的啮合行星齿轮和齿圈。 行星齿轮通过刚性地附接到齿轮前侧的轴直接连接到刀架。 行星齿轮的后侧是偏心安装的驱动轴。 环绕行星齿轮的外齿是一个较大的固定环形齿轮，内齿与齿轮齿不断啮合。 当这些齿变得接合时，行星齿轮在其自身的轴上旋转并且在更大的半径中也绕着环形齿轮旋转。 在优选实施例中，围绕行星齿轮的轴的旋转是行星齿轮围绕齿圈旋转的三分之一。 当考虑到刀架的形状时，这两个反转的复合效应是切割位转录并切出方孔。

Abstract: A floor scrubber is disclosed including a frame including a drive wheel, rear wheels, brushes, vacuum squeegee system, batteries, solution tanks, and an operator seat. The rear wheels are rotatably mounted on the opposite ends of a steel rod. Arms are attached rigidly to the axle and each include a cylindrical pivot in which an elastomer bushing is press fit. Pivot pins extend through first and second pairs of first and second plates and the elastomer bushing for pivotably mounting the arms to the frame while isolating any transmitted vibrations. Elastomeric isolator mounts are provided each including a frusto-conical shaped body and each having a nut embedded in the lower end for threadable receipt of a bolt passing through an attachment plate attached to the axle. The upper ends of the elastomeric isolator mounts each include a plate secured thereto and secured to the frame.
