  • Patent number: 10760735
    Abstract: The current invention includes manifold having multiple outputs and at least one input for lubricant to be pumped at high pressure from a skid or trailer to a particular frac valve when the valve requires lubrication. Generally such frac valves require lubrication on an hourly schedule or less. Each output port on the manifold is fitted with an on/off valve that allows remote operation such as pneumatic, hydraulic, electro-pneumatic operation, or other known remote operation system. The pump or pumps are also configured for remote operation. A controller is then provided so that each circuit allows, upon command, lubricant to be pumped from the lubricant reservoir, through the pump, to the manifold, through each remotely operable valve, via each output port, through an appropriate rated hose, then to the lubrication or other port on each frac valve. Generally, once connected each frac valve remains connected to the system to allow the operator to cause lubricant to flow to each valve upon command.

  • Patent number: 10746352
    Abstract: A lubricant coating device preventing coating unevenness of lubricant powders is provided. The lubricant coating device includes a solid lubricant, a coating member and a film shaping member. The coating member in which first fibers composed of a material located on a positive polarity side and second fibers composed of a material located on a negative polarity side, on a triboelectric series with respect to the material of the solid lubricant are implanted, coats lubricant powders scraped off from the solid lubricant onto the image supporter. The film shaping member comes in contact with the image supporter and presses the lubricant powders onto the image supporter, to shape the lubricant powders into a form of a film. A scraping amount of the lubricant powders by the first fibers and a scraping amount of the lubricant powders by the second fibers are set to become substantially identical.

  • Patent number: 10737905
    Abstract: A braking arrangement for an elevator arrangement includes a speed sensor arrangement for generating an over-speed signal of a moving component of the elevator arrangement, a hydraulic brake arrangement for generating a braking action of the moving component upon application of a hydraulic pressure and an actuator arrangement for generating and applying the hydraulic pressure to the hydraulic brake arrangement. The braking arrangement includes a control connected to the speed sensor arrangement and in response to the over-speed signal initiating an ABS braking process by controlling the actuator arrangement to repeatedly increase and decrease the hydraulic pressure to the hydraulic brake arrangement with a repetition time interval that is successively extended during the ABS braking process. The braking arrangement enables safe and reliable deceleration of the moving component, such as a car or a counterweight, while avoiding an excessive jerk by smoothly increasing the braking action.

  • Patent number: 10669128
    Abstract: A system controls leakage in a pit which contains equipment which uses pressurized hydraulic fluid. A tap communicates with a space holding leaked fluid, and directs leaked fluid to a fluid sump. A pump moves fluid from the fluid sump to a hydraulic fluid recapturing holding tank located outside the pit above a fluid reservoir. Fluid from the fluid reservoir is selectively relocated into the fluid reservoir, which re-supplies the equipment. An electronic control panel located outside the pit interacts with a remote computer to provide a remote user with information concerning operation of the system and to allow the remote user to monitor and control at least certain operations of the system, and which processor also controls operation of the pump and actuating valve. All of the mechanical and electrical equipment of the system is located outside of the pit.
