Publication number: 20240069161Abstract: In one embodiment, a lidar system includes a wavelength-tunable light source configured to emit pulses of light, each emitted pulse of light having a particular wavelength of multiple different wavelengths. The lidar system also includes a scanner configured to scan the emitted pulses of light across a field of regard of the lidar system. The scanner includes (i) a beam deflector configured to angularly deflect each emitted pulse of light along a first scan axis according to the particular wavelength of the emitted pulse of light and (ii) a scan mirror configured to scan the emitted pulses of light along a second scan axis different from the first scan axis. The lidar system further includes a receiver configured to detect a received pulse of light that includes a portion of one of the emitted pulses of light scattered by a target located a distance from the lidar system.Type: ApplicationFiled: January 4, 2023Publication date: February 29, 2024Inventors: Joseph G. LaChapelle, Jason M. Eichenholz, Roger S. Cannon, Stephen D. Gaalema, William R. Clark, Alex Michael Sincore

Patent number: 6032886Abstract: An adjustment mechanism for a rock crusher has an insert installed in the thread form of a bowl support and a locking ring. A bowl is threadably installed in the bowl support and lock ring assembly and is movable toward and away from a cone assembly. The insert is of a material that differs from that of the bowl and bowl support. The lock ring is movable to frictionally lock the thread forms of the bowl and bowl support against each other. The inserts prevent the galling and deformation of the thread forms previously experienced.Type: GrantFiled: March 18, 1999Date of Patent: March 7, 2000Assignee: Johnson Crushers InternationalInventors: Daniel C. Drinkwater, Roger M. Clark, Gerald E. Parker, David F. Peaks, Gary Heeszel, Randy Orre

Patent number: 5971306Abstract: A gyratory crusher with a tramp iron relief system having an annular manifold is disclosed. The gyratory crusher includes a frame, with the frame including a circumferential manifold ring having an internal hydraulic channel. A bonnet and a gyratory head are supported by the frame, with the gyratory head being spaced relative to the bonnet such that a crushing chamber is formed therebetween. The bonnet is adjustably mounted to the frame to permit relative vertical movement between the bonnet and the gyratory head. A hydraulic relief system is provided and includes at least one hydraulic cylinder operatively interconnecting the bonnet and the frame and being in flow communication with the hydraulic channel. The hydraulic relief system is arranged to allow uncrushable material to automatically pass through the crushing chamber.Type: GrantFiled: October 29, 1998Date of Patent: October 26, 1999Assignee: Cedarapids, Inc.Inventors: William A. Ganser, IV, Joseph E. Musil, Donald W. Henry, Mark Hunt, David A. Ostergaard, John C. Vendelin, Peter Alford, Roger M. Clark, Jon Juhlin, James Mitchell, Gerald E. Parker

Patent number: 5950939Abstract: A cone crusher for rock that has a rotatable wedge plate that rotatably supports a cone for crushing rock. The wedge plate has bores for receiving sized weights for balancing the rotating assembly. The bores place the weights out of the travel path of the crushed material and are not subject to wear or abrasion during operation of the crusher.Type: GrantFiled: August 24, 1998Date of Patent: September 14, 1999Assignee: Johnson Crushers InternationalInventors: Daniel C. Drinkwater, Roger M. Clark, Gerald E. Parker, David F. Peaks

Patent number: 5875981Abstract: A gyratory crusher includes a frame, a bonnet, a gyratory crusher head, supported by the frame and being spaced relative to the bonnet such that a crushing chamber is formed therebetween, and a hydraulic channel formed integrally within the frame. First and second hydraulic cylinders are attached to the frame and support the bonnet on the frame, and the first and second hydraulic cylinders are connected to the hydraulic channel so as to be in hydraulic communication therewith. First and second hydraulic accumulators are supported by the frame and are in hydraulic communication with the hydraulic channel and the hydraulic cylinders. The hydraulic accumulators and the hydraulic channel are arranged to allow uncrushable material to automatically pass through the crushing chamber.Type: GrantFiled: June 12, 1997Date of Patent: March 2, 1999Assignee: Cedarapids, Inc.Inventors: William A. Ganser, IV, Joseph E. Musil, Donald W. Henry, Mark Hunt, David A. Ostergaard, John C. Vendelin, Peter Alford, Roger M. Clark, Jon Juhlin, James Mitchell, Gerald E. Parker

Patent number: 5803382Abstract: A gyratory crusher having a frame with a lower frame portion, a crusher head, a mounting mechanism for pivotally and gyrationally mounting the crusher head on the lower frame portion such that the crusher head operably gyrates between a closed side setting and a corresponding open side setting, a seal mechanism for operably protecting the mounting mechanism. The seal mechanism includes a flexible member having an outer edge, sealingly connected to the crusher head, and an inner edge, sealingly connected to the lower frame portion by an outer bearing race secured to the inner edge, an inner bearing race secured to the lower frame portion, and bearing balls captured between the outer and inner bearing races. The flexible member may have a single wall structure with a corrugation-like configuration, or a double wall structure with an inflatable bladder therebetween.Type: GrantFiled: January 21, 1997Date of Patent: September 8, 1998Assignee: Cedarapids, Inc.Inventors: William A. Ganser, IV, Joseph E. Musil, Donald W. Henry, Mark Hunt, David A. Ostergaard, John C. Vendelin, Peter Alford, Roger M. Clark, Jon Juhlin, James Mitchell, Gerald E. Parker

Patent number: 5350125Abstract: A conical crusher head of a gyratory cone crusher is supported by a spider arm cradle. Radially disposed and circumferentially evenly spaced spider arm type support members of the cradle extend outwardly through an annular material discharge path in the lower portion of the crusher and through the generally cylindrical frame of the crusher. A gyratory drive mechanism is disposed annularly about the material flow path region and is coupled to the head support members to gyrate the head.Type: GrantFiled: July 1, 1993Date of Patent: September 27, 1994Assignee: Cedarapids, Inc.Inventor: Roger M.
