  • Publication number: 20210140134
    Abstract: In a machine for driving screw anchors and other foundation components, a desired embedment depth is calculated based on a minimum required embedment depth, work point height and length of available upper leg sections. Once calculated, the machine automatically drives the screw anchor to the depth so that one of the available upper leg lengths will fit between the driven screw anchor and apex truss hardware. If uplift is detected during driving, the machine will add additional embedment depth. In-situ validation of driven screw anchors may be performed after the embedment depth is reached.

  • Publication number: 20210115642
    Abstract: Various embodiments of the disclosure enable installation of a utility scale solar array or other project requiring a site survey and survey markers at every ground penetration to be replaced with survey markers only at the end of each row. In addition, machine mast alignment for driving H-piles with an impact or vibratory hammer, or for driving screw anchors, helical anchors or other foundation with a rotary driver to be automated with the use of range finding lasers to orient the driving mast in X, Y and Z as well as pitch, roll and yaw based on range finding laser measurements.

  • Patent number: 4502342
    Abstract: A pulsed shaker shocker is provided in which an intermittent pulsed action is provided to the containers carrying liquid to enhance the shaking action for the liquid carried in the containers. Such shaking action is found for separatory type shakers, and the pulsed action enables a more efficient shaking action to be obtained. The pulsed nature of the shaker shocker more closely resembles the manual shaking action, and this way, more efficient shaking may be obtained.

  • Patent number: 4202634
    Abstract: A clamp means is provided for holding at least one vessel so that the vessel can be agitated by a drive means with the clamping means permitting the vessel to move with the clamping means defining the null point of the movement. The clamp means may provide a rack for resiliently clamping the vessel. Preferably, the clamping means is for resiliently clamping the vessel at a position remote from the bottom thereof. Drive means are provided for imparting motion, such as orbital motion, to the agitating means whereby fluent contents of the vessel are agitated. The apparatus is adapted for the holding and agitating a single or a plurality of vessels, such as a plurality of test tubes. The drive means also is capable of pulsing the orbital motion.
