Brake wear control system
ActiveUS20100286881A1Lost revenueFrequent inspection and maintenanceAnalogue computers for trafficAxially engaging brakesBrake forceMechanical engineering
A system, apparatus and method provide a means for managing wear of brake friction material such that even friction material wear is experienced between brakes. The available friction material of each brake is monitored to determine an amount of wear. Based on the amount of wear, a braking force applied by each brake may be varied to ensure even wear between brakes.

A germicidal absorptive material for use in surgical packings, wound bandages, sanitary tampons and bed sore prevention and / or treatment uses is provided by a foam-like matrix of hydrophilic polyurethane polymer to which application-specific loads of a germicidal disinfectant dye have been made. Polyurethane polymer of various densities and thicknesses exhibits an exceptional ability to absorb different levels of a number of disinfectant dyes, both basic and acidic, such as gentian violet and methylene blue, respectively. The relationship between dye-load and application-specific uses permits a totally-bound gentian violet pad to be used as a conventional bandage or pad on a surface wound with the capability of preventing the incursion of external pathogens from entering the wound through the pad, where the pathogens are killed by the bound-dye. The wound exudate is absorbed safely by the pad, where wound-originating pathogens are also killed. When the loaded dye's concentration is saturated by exceeding the bound-dye limit, the limited free-dye is available to be delivered to the wound, particularly deep wounds, to rapidly kill pathogens in the wound. The free dye delivery pad can then be replaced by the bound-dye pad to absorb the wound exudate.

Overload protection type electrical starting duplicate gear and starting system
InactiveCN103726968AGood transmission effectFrequent replacementPortable liftingElectric motor startersElectricityStatic friction
The invention discloses an overload protection type electrical starting duplicate gear and a starting system. The overload protection type electrical starting duplicate gear comprises a duplicate gear shaft, a gear body I and a gear body II, wherein the gear body I and the gear body II are arranged on the duplicate gear shaft in a drive matching mode. The duplicate gear shaft is sleeved with the gear body II so that an inner conical surface of the gear body II and an outer conical surface of the duplicate gear shaft can form a conical surface pair. The gear body II has axial force for locking the conical surface pair and enabling the sliding torsion value of the conical surface pair to be larger than or equal to the electrical starting torsion value. When the reverse dragging phenomenon occurs and the torsion value exceeds the largest static friction force between the conical surfaces due to the fact that an engine suddenly slows down or stops under heavy loads and great inertia in the high-speed running process, the inner conical surface and the outer conical surface can slide, in other words, the gear body II and the duplicate gear shaft can slide relative to each other, and therefore the gear and a starting clutch of the whole electrical starting system can not be damaged, and the overload protection function is achieved. In the use process, the taper angle, the roughness of the conical surfaces and the axial force can be set according to the actual requirements, and therefore the required largest static friction force can be set.
