it is provided for the following features to be achieved: the transmission ratio of the first gearbox between the fixed displacement motor (74) and the associated travelling device is lower than the respective transmission ratios of the second gearboxes (92), which are each arranged between the respective hydraulic variable displacement motors (72) and the respective travelling device, and/or the displacement volume of the fixed displacement motor (74) is smaller than the maximum displacement volume of the variable displacement motors (72).

A method for forming a depression into a glass object for storing cremated remains may include coating a metal sphere with diamond dust. The method may include spinning the diamond dust coated metal sphere via a spindle and motor arrangement. The method further may include pressing the spinning diamond dust coated metal sphere against at least one face of the glass object. Furthermore, the method may include applying coolant while pressing the spinning diamond dust coated metal sphere against at least one face of the glass object. The continuous spin and pressure of the diamond dust coated metal sphere against at least one face of the glass object grinds the depression into the glass object.

Portable linear transformer for laminated gypsum boards, that comprises a central module (2) in a structure having a converting bridge (4) where different converting tools (5) are located, preferably incorporated on a runner (19) that allows to fasten them in different positions by means of screws with knob (20). The central module (2) preferably shows the precision calibration rollers, one of input (6) and the other of output (7), on which the board (P) to be converted slides and the lateral modules (3) with a series of easels (8), with carriage rollers (9) on which the said board (P) is supported and also slides, coplanar to the said input (6) and output (7) rollers. Preferably, the linear and hand-held converting machine also comprises two lateral modules (3) that are fastened on both sides of the central module (2).

A self-contained truck-mounted brick laying machine can include a frame that can support packs or pallets of bricks placed on a platform. A transfer robot can pick up and move the brick(s). A carousel can be coaxial with a tower. The carousel can transfer the brick(s) via the tower to an articulated and/or telescoping boom. The bricks can be moved along the boom by, e.g., linearly moving shuttles, to reach a brick laying and adhesive applying head. The brick laying and adhesive applying head can mount to an element of the stick, about an axis which is disposed horizontally. The poise of the brick laying and adhesive applying head about the axis can be adjusted and can be set in use so that the base of a clevis of the robotic arm mounts about a horizontal axis, and the tracker component is disposed uppermost on the brick laying and adhesive applying head. The brick laying and adhesive applying head can apply adhesive to the brick and can have a robot that lays the brick. Vision and laser scanning and tracking systems can be provided to allow the measurement of as-built slabs, bricks, the monitoring and adjustment of the process and the monitoring of safety zones. The first, or any course of bricks can have the bricks pre machined by the router module so that the top of the course is level once laid.

Embodiments of the invention are directed to cutting tool assemblies, material-removing machines that include cutting tool assemblies, and methods of use and operation thereof. In some embodiments, the cutting tool assemblies described herein may be used in material-removing machines that may remove target material. For example, the cutting tool assemblies may include one or more superhard working surfaces and/or one or more shields.

A cutter bit for a work tool on a machine includes a leading end, conical-shaped tip portion, a rearward, frustoconical-shaped tip portion extending axially rearwardly from the leading end, conical-shaped tip portion, an annular ledge extending radially outwardly from a trailing edge of the rearward, frustoconical-shaped tip portion, a frustoconical-shaped body portion extending axially rearwardly from an outer circumferential edge of the annular ledge, a cylindrical collar portion extending axially rearwardly from a trailing edge of the frustoconical-shaped body portion, and a trailing end, cylindrical-shaped shank portion extending axially rearwardly from the cylindrical collar portion. The cutter bit may also include a plurality of circumferentially-spaced ribs projecting radially outwardly from an outer peripheral surface of at least one of the leading end, conical-shaped tip portion, the rearward, frustoconical-shaped tip portion, or the frustoconical-shaped body portion.

A control system for a base supporting a boom assembly comprises long telescopic boom and telescopic stick. Mounted to the remote end of the stick is an end effector that supports a robot arm that moves a further end effector to manipulate the items. The robot arm has a robot base, and mounted above the robot base is a first target in the form of a position sensor, that provides position coordinates relative to a fixed ground reference. Mounted on the end of the robot arm immediately above the end effector is a second target that provides position coordinates relative to the fixed around reference. The fixed ground reference tracks the sensors and feeds data to the control system to move the stick with slow dynamic response and to control movement of the robotic arm and end effector with fast dynamic response.

A machine for milling pavement such as a rotary mixer or road planer includes a cutting rotor that is vertically adjustable with respect to the frame and that is accommodated in a rotor enclosure. The milling machine may be associated with a visual camera network having one or more cameras located about the milling machine with a field of view toward the rotor enclosure and work surface. An image augmentation system can generate a reference line augmentation to superimpose over one or more visual images obtained by the cameras and display the augmented images on a visual display.

A cutter head assembly for cutting slots in a surface includes a cutter drum. A plurality of first cutter bits are connected to the cutter drum and extend radially outwardly a first distance from a cutter drum face. First and second cutter plates are connected to first and second sides of the cutter drum. A plurality of second cutter bits are connected to the first and second cutter plates and extend radially outwardly a second distance from the cutter drum face, the second distance being greater than the first distance.
