Updated operating code and parameters can be reprogrammed into a modem system with no disassembly of the modem hardware. The modem system includes a memory chip in which operating code and parameters are stored. Two control programs control the reprogramming of updated operating code. One of the control programs is designed for manufacturing and testing purposes. The other control program allows remote reprogramming of updated operating code or parameters from a remote location such as a customer site. A user can thus remotely upgrade system firmware with updates, bug fixes, enhancements or other new releases of system operating code by downloading the update over a phone line to a host PC and reprogramming the memory chip of the modem over the serial port from the host PC. The user can also remotely upgrade the modem system firmware by directly programming the memory chip of the modem without the assistance of the host PC. The modem system is portable, obtaining power from a standard 9 volt battery.

An improved self-propelled carpet cleaning machine comprises a body movably mounted by a drive wheel. The body is powered by a drive motor which may be selectively connectable either to an AC power source located separately from the body or to a DC power source contained in the body. In addition, the body includes a first storage chamber for receiving fresh cleaning solution therein and a second storage chamber for receiving spent cleaning solution therein. The first and second storage chambers are provided by a flexible membrane which divides an enclosed cavity into two parts. A scrubbing means is also carried by the body in back of the drive wheel on the body. The scrubbing means includes means for applying the fresh cleaning solution to the carpet, a brush roller for agitating the carpet fibers contacted by the cleaning solution to remove foreign material therefrom, and a vacuum shoe for removing the spent cleaning solution from the carpet and placing that solution in the second storage chamber.

A generally rectangular open topped vessel with vertical walls around the periphery of a floor consisting of two integrally formed levels, the lower level being at one end providing a footwell and having a drain therein. Near the end of one side wall, in the area where the footwell is located, is a door opening. This door opening has a ferromagnetic faced door stop around the edge. A door is hingedly attached to the edge of the opening such that it swings horizontally inward towards the nearest adjacent end wall. The door has a flange along its two vertical edges and along its bottom horizontal edge. Mounted concentrically on the flange are two magnetic gaskets such that when the door is closed the gakets force a water tight seal with the ferromagnetic plate on the door stop. A second drain is located in the surface of the bottom door stop such that when the door is closed water in the vessel cannot reach the drain due to the sealing of the outer gasket. With the door open water will go down this drain before it reaches the door opening.

A method for lubricating the passage of a conveyor comprising applying an undiluted lubricant composition through non-energized nozzles to at least a portion of the conveyor, the lubricant composition comprising a silicone emulsion and a water-miscible lubricant, the lubricant composition having a viscosity of less than 40 centipoise when measured using a Brookfield viscometer with an RV2 spindle at a spindle speed of 20 RPM and the lubricant composition being substantially free of a triethanolamine salt of dodecyl benzene sulfonic acid.

The passage of a container along a conveyor is facilitated by applying to the container or conveyor aqueous compositions containing hardness ions. The compatibility of the aqueous compositions with PET bottles is improved when the ratio of hardness as CaCOto alkalinity as CaCOis greater than about 1 to 1.
