A cleaning kit for use in cleaning surfaces in clean rooms, semiconductor fabrication plants, pharmaceutical manufacturing facilities, etc. A stack of extremely clean wipers is packaged together with a container of cleaning fluid in a liquid-tight outer container. The kit is stored until just before it is to be used. Fluid is released from the inner container into the wipers. In one embodiment, the inner container is frangible and is broken by application of hand pressure to the outside of the outer container. The cleaning liquid is allowed to soak into the wipers, and the wipers are removed from the outer container for use. The container can be resealed to protect the wipers after the package has been opened. This device and method minimize deterioration of the wiper material due to prolonged contact with the cleaning fluid, and minimize the loss of effectiveness of substances such as biocides which might deteriorate due to prolonged contact with the wiper material.

Cleaning device and method

Cleaning method

A cleaning kit for use in cleaning surfaces in clean rooms, semiconductor fabrication plants, pharmaceutical manufacturing facilities, etc. A stack of extremely clean wipers is packaged together with a container of cleaning fluid in a liquid-tight outer container. The outer container is vacuum-sealed. The kit is stored until just before it is to be used. Fluid is released from the inner container into the wipers, preferably by the use of a puncturing device operable to puncture one of the walls of the inner container by the application of pressure in a limited area on the outside of the outer container. The cleaning liquid is allowed to soak into the wipers, and the wipers are removed from the outer container for use.

The cleaning liquid is allowed to soak into the wipers, and the wipers are removed from the outer container for use. The container can be resealed to protect the wipers after the package has been opened. The puncturing device is located away from the edges of the package to minimize the chances of accidental puncture. This device and method minimize deterioration of the wiper material due to prolonged contact with the cleaning fluid, and minimize the loss of effectiveness of substances such as biocides which might deteriorate due to prolonged contact with the wiper material.

An article of manufacture, such as a wiper, especially suited for use in a controlled environment, such as a cleanroom environment, and a method for controlling the entry of deleterious particles into the controlled environment, within which environment a process is carried out, the article being constructed of fibers of a synthetic polymeric material of the type including only constituents which are relatively benign in that the included constituents will be less likely to have a deleterious effect upon the process carried out in the controlled environment or upon the product of that process, the method including constructing the article of such fibers, the preferred synthetic polymeric materials including no more than only negligible amounts of inorganic constituents or metallic constituents, one such preferred synthetic polymeric material being nylon bright.

Particulate contamination control in cleanrooms

The feed surfaces of feed rollers along the paper path of an imaging machine are cleaned by passing a cleaning sheet along the paper path through the imaging machine, the cleaning sheet including a substrate carrying a coating of synthetic polymeric material in a pattern which assures contact between the coating and the feed surfaces to be cleaned, the material of the coating having a tack which enables the coating to pick off particles of unwanted material from the feed surfaces and capture the picked-off particles for movement with the cleaning sheet along the paper path and out of the machine.

Cleaning sheet and method for cleaning paper path feed roller surfaces

A method and a wiper for reducing particulate contamination which otherwise might result from the use of the wiper in a controlled environment, such as that maintained in a cleanroom, the wiper being of the type constructed at least partially from a thermoplastic fabric material by severing the wiper along peripheral edges thereof from a sheet of such material having indeterminate dimensions, the method and the wiper providing a fused border in the material along the peripheral edges of the wiper and extending inwardly into the wiper a distance great enough to provide the fused border with sufficient area and sufficient tear-strength to maintain therein segments of the material of the wiper which otherwise might be released from the peripheral edges of the wiper during use of the wiper, yet small enough to maintain pliability and absorbency in the wiper for wiping procedures. In one embodiment of the wiper, two outer plies of the material are joined along the fused border to establish a sealed envelope within which is placed an inner ply of absorbent material isolated from the controlled environment by the outer plies of material and the fused border.

Wipers for cleanroom use

Portable computer terminal housing for accessing and inputting patient

A computer terminal device includes a flat screen display element and a touch-sensitive element. Simulated keyboards can be displayed on the display element and, in response to the touching of the simulated keys, generate appropriate control signals. The same flat screen display can also be used to display computer output, either the result of calculations or the result of information retrieval requests. The slim silhouette of this terminal makes it ideal for hostile environments such as the factory floor or the hospital room.
