Patent number: 10696486Abstract: A tensioning system maintains tension within a target range for an endless belt of a conveyor. The tensioning system may include a movable carriage that supports a take-up pulley that provides tension to the conveyor belt. The tensioning system may also include various hydraulic components supported on a repositionable cart. One example hydraulic component is a hydraulic cylinder that is in tension between the movable carriage and the repositionable cart. An accumulator initially pressurized to a predetermined pressure may be connected so as to supply pressure to the hydraulic cylinder. One or more flow-restriction valves between the hydraulic cylinder and the accumulator may substantially increase a pressure in the hydraulic cylinder during phases when a piston rod is rapidly drawn out of the hydraulic cylinder by tension waves in the endless belt. Further, a check valve may permit substantially unimpeded fluid flow from the accumulator to the hydraulic tensioning cylinder.Type: GrantFiled: January 16, 2018Date of Patent: June 30, 2020Assignee: THYSSENKRUPP INDUSTRIAL SOLUTIONS (USA), INC.Inventors: Martin S. Lurie, Mark Alspaugh, Ruben E. Lezius, Kalin Tonchev, R. Steven Kasper, Vladimir Svirsky

Patent number: 9415940Abstract: A conveyor take-up device may include a carriage, a pulley, a counterweight assembly, at least one connector, and at least one safety restraint. The carriage may be movably joined to a support structure and may support the pulley, which may be configured for operative association with an endless conveyor belt. The counterweight assembly may include a counterweight arm, a tension arm, and a counterweight. The counterweight arm may be pivotally joined to the support structure and configured to move between upper and lower limit positions. The tension arm may extend generally transversely from a first end portion of the counterweight arm with the counterweight supported by the counterweight arm distal from the tension arm. The connector may be joined to the carriage at one end portion of connector and to the tension arm at a second end portion that is distal the first end portion of the connector.Type: GrantFiled: August 16, 2013Date of Patent: August 16, 2016Assignee: THYSSENKRUPP INDUSTRIAL SOLUTIONS (USA), INC.Inventors: Svetoslav Slavov, Vladimir Svirsky, Martin S.

Patent number: 8347935Abstract: A rigid retractable patio or window awning includes a number of rigid panels disposed in a tiered relationship with each other. Each lower panel is slidably connected with its respective upper panel via a set of slides. The top panel remains stationary. An awning operating mechanism includes arms connected via swivel joints with the bottom panel. Each arm also is connected via a threaded nut with a drive screw. The awning is extended by rotating the drive screw, which causes the nuts to travel along the drive screw causing the arms to push the bottom panel outwardly and the bottom panel to pull along any intermediate panels. The awning is retracted by rotating the drive screw in the opposite direction.Type: GrantFiled: February 12, 2010Date of Patent: January 8, 2013Inventors: Alexander Svirsky, Vladimir Svirsky

Patent number: 8037920Abstract: A retractable rigid window awning includes a number of U-shaped panels pivotally attached to a building on the sides of a window. In the retracted position, the panels are disposed above the window, in tiers. Each panel has a pair of actuators that enable its extension and retraction. Each actuator is attached to the panel at one end and to a movable nut at the other end via articulated joints. The nuts are installed on a driving screw attached to the building. The awning is extended by rotating the screw, which causes the nuts to travel along the screw. The actuators push their respective panels out and tilt them down. Depending on the length of actuators, panels travel different distances from the building creating a continuous shade over the window. The awning is retracted by rotating the screw in the opposite direction.Type: GrantFiled: April 1, 2009Date of Patent: October 18, 2011Inventors: Alexander Svirsky, Vladimir Svirsky
