Title: Floor cleaning machine with dust control apparatus and associated method of use
Inventor: GROSZE SCOTT F
IPC: B24B55/10
Filed: 2004-05-03
Abstract: A floor cleaning machine with dust control apparatus can assist in capturing dust created as a by-product during normal operations. The dust control apparatus is particularly applicable to propane-powered burnishers that use rotating pads to remove built up wax from hard surface floors. A floating scoop is attached to a floating hoop assembly to direct dust away from the rotating pad. The scoop is located tangentially to the housing that surrounds the rotating pad. An inlet to the housing facilitates airflow through the housing to pick up dust, which exits through the scoop. A containment canister with removable filter is in communication with the scoop. The air and entrained particulate (dust) swirls around the filter in a circular flow path to help separate the particulate from the air. The filtered air exits the canister and returns to the atmosphere.

Abstract: An improved insulating glass lite assembly having at least two glass lites spaced apart one from the other by an inner peripheral spacer coated by at least one sealant, the glass lites defining therebetween an inner air space; and a communication channel in communication with the inner air space and ambient air, the improvement wherein the communication channel is in communication with a member having walls defining a chamber adapted to receive a moisture absorbent material, the member operably being in communication with the ambient air as to allow of satisfactory rapid pressure equalization between the inner air space and the ambient air. The apparatus allows the interior air space pressure of the insulating glass panel assembly to more rapidly equalize with the exterior atmospheric pressure, which allows the two lites of the assembly to remain parallel, and accordingly reducing the stress on the sealant and glass edge. This not only extends the life of an insulating glass panel assembly, but reduces the risk of premature failure of the assembly. In addition, since the two lites remain parallel, one to the other, this maintains the appearance of the overall assembly. A preferred communication channel is constituted as a breather tube.

Abstract: In a communication system, controlling transmission power and transmission data rate to reduce transmission power fluctuations. Data for transmission is queued in a data storage queue, and the amount of data in the queue is represented by a queue length. When the queue length is within a predetermined range, queued data is transmitted at a first power level and data rate. When a determination is made that the queue length is outside the predetermined range, a corresponding change to transmission power and data rate is made.  When the queue length is exceeds a predetermined upper limit, transmission power and data rate are increased. When the queue length is less than a predetermined lower limit, transmission power and data rate are decreased. In a further aspect, the magnitude of changes to transmission power and data rate are based, at least in part, on the magnitude by which the queue length is outside the predetermined range.
