A software method for obtaining an address of a thread-local variable while executing a computer program is described. The method designates a memory location to store an address of a function. The method, after the computer program starts to run, obtains the address of the thread-local variable by executing a resolver function whose address is stored in the memory location when a module that references the thread-local variable is loaded. The resolver can be a lazy resolver function or other resolver functions optimized for specific modules or variables.

A mobile vehicle washing apparatus in which the length, width and height of the apparatus may each be adjusted to the size of the vehicle to be washed and for easier transport. The frame dimensions may be adjusted by a system of cranks found on each frame member that may need to be adjusted.

Powered brush members are used in the apparatus as a means to scrub vehicle surfaces. The cleaning and rinsing fluids pass through a series of hoses and nozzles mounted about the frame so that the tops and left and right sides of the vehicles being cleaned may be covered by said fluids.

The invention relates to a preheating starting method for an aluminium electrolysis cell, and the preheating starting method comprises the following preheating starting processes: (1) drilling on the upper surface of a carbon or graphite electrode, and pre-embedding a heating element in the electrode; (2) heating a hearth by using a heating assembly according to a roasting curve; (3) after reaching a target temperature, adding a solid or liquid electrolyte until reaching a required electrolyte level, regulating the power of the heating assembly, and primarily building heat balance and inner hearth mold required by the electrolysis cell; (4) introducing direct current for electrolyzing a preheating electrode; and (5) gradually utilizing an electrode which normally operates to replace the preheating electrode carrying the heating element. The method disclosed by the invention can evenly heat; in the preheating process, an anode and the bus do not need flexible connection; a traditional cell of which the cathode is in an abnormal-shape structure can be effectively preheated, and an inert electrode aluminium electrolysis cell can be effectively preheated and started; and a stable electrolysis environment is built, current efficiency is improved, and the service life of the electrode is prolonged. The preheating electrode can be reused to lower electrolysis cell starting cost.

The invention discloses an energy-saving type quick start method for a supercritical unit or an ultra-supercritical unit. According to the method, steam from another resource is used for heating supplied water so that a boiler can be indirectly heated, and the thermal stress of a heated surface is reduced when the boiler is started so that the heating rate of the boiler can be improved; meanwhile, the heated high-temperature supplied water is converted into steam-liquid two-phase flow through throttling and pressure reduction, the flowing scouring action of the steam-liquid two-phase flow is far superior to the effect of thermal-state washing, and in other words, the boiler can complete thermal-state washing under the non-ignition condition, and can preheat the whole heated surface before ignition till certain pressure is reached. After ignition of the boiler, due to the fact that enthalpy of subcooling on an inlet of a water wall is eliminated, the problem of water power can be readily solved and the input speed of fuel can be increased. Meanwhile, by adjusting the open degree of a turbine bypass valve, the flow, the temperature rising speed and the pressure rising speed of main stream and reheat steam are controlled, and the temperature rising speed of the heated surface of the boiler is increased; when the temperature of the main steam and the temperature of the reheat steam are larger than the temperature of a turbine heating valve, valve heating is started, and a main machine can early satisfy the impulse starting condition.

The present invention proposes a leasing arrangement of composite railroad ties constructed of, for example, recycled automobile tires, to a customer over a lengthy term while ownership in the ties remains with the supplier/leassor. The leasing arrangement can be spread over twenty years or longer, such that the initial start up costs is a fraction of that for wood ties, much less composite ties, and the customer also realizes the benefits of the enhanced durability of the composite ties. The supplier may also agree to replace the composite ties as necessary, and thus the customer has a fixed and manageable annual (or other incremental) cost that provides predictability and low cost insurance that is not available for purchased ties.
