Title: Tire inflation method and apparatus
Inventor: SOWRY CLIVE ROBERT
IPC: B60S5/04
Filed: 1997-02-07
Granted: 2005-07-12
Abstract: The method and apparatus allow deflating a tire and thereafter re-inflating it using,a single source of pressurized inert gas.      The pressurized inert gas is used to increase the rate at which gas is vented to the atmosphere from the tire during deflation.      Once the pressure inside the tire reaches the sub-atmospheric level, an outlet valve is closed and the inert gas is forced into the tire until it is re-inflated. This method and apparatus allow simplifying the process, compared to previously known apparatus and methods.

Title: A method of incorporating independent feedforward control in a multivariable predictive controller
Inventor: LU ZHUXIN J
IPC: G05B11/32
Filed: 1996-06-14
Granted: 2006-08-22
Abstract: A process control system includes a feedback controller and has at least one manipulated variable and one controlled variable. A feedforward loop is included, the system being subject to a disturbance.  Independent feedforward control is incorporated into the feedback controller which comprises the following steps. A feedforward control funnel and a feedback control funnel are defined for each cv, specifying a time T FF in which the disturbance is to be eliminated and a time T FB in which the controlled variable is to reach a steady state value, respectively. The shorter of the feedforward control funnel and the feedback control funnel is selected. If T FF is less than T FB, the feedback control speed is compensated such that the feedback controller speed is not increased. If T FF is greater than or equal to T FB, no compensation is performed, thereby effectively providing independent tuning parameters for the feedforward control solution and the feedback control solution. New values of the cvs are calculated and the process controlled by the newly calculated cvs.

Granted: 2005-09-06
Abstract: In a method for drying coating films on coated components, microwaves are generated by at least one magnetron (3A) in at least one microwave generator module (3) and introduced into a drying chamber (2A) through one or more waveguides (4). Air or another gas is blown from a blower (5) into the drying chamber (2A). An additive agent comprising a dipolar or polarizable molecular composition is mixed into the gas to form a gas mixture within the drying chamber (2A). The coated components (9) are placed into the drying chamber (2A) in a batch or continuous flow-through process. The microwave energy vibrationally excites and heats the additive agent in the gas mixture, which in turn heats the coating film (9') on the components (9). Alternatively, the additive agent may be mixed or applied directly in the coating film substance, so as to achieve direct heating of the coating film, or so as to evaporate from the coating film into the gas to form the gas mixture. The gas is preferably air, and the additive agent is preferably water vapor in a prescribed and controlled relative proportional content within the range from 20% to 90%, which is maintained within the drying chamber.      The component may be a metal component or a non-metal component, and the coating may be a water-thinnable or solvent-containing one-, two-, or more component lacquer based on an epoxy, or a polyurethane, or an alkyde resin, or an acrylic resin. Uniform drying of the coating film is achieved even on components having a complex geometry.
