  • Patent number: 6148832
    Abstract: An apparatus for in-situ cleaning of polysilicon-coated quartz furnaces are presented. Traditionally, disassembling and reassembling the furnace is required to clean the quartz. This procedure requires approximately four days of down time which can be very costly for a company. In addition, cleaning the quartz requires large baths filled with a cleaning agent. These baths occupy a large amount of laboratory space and require a large amount of the cleaning agent. Cleaning the furnace in-situ eliminates the very time consuming procedure of assembling and disassembling the furnace and at the same time requires less laboratory space and less amount of cleaning agent. The polysilicon remover may be either a mixture of hydrofluoric and nitric acid or TMAH. TMAH is preferred because it less hazardous than hydrofluoric acid and compatible with more materials. The cleaning agent may be introduced into the furnace either from the built-in injectors or from additionally installed injectors.

  • Patent number: 5727350
    Abstract: The self cleaning rain gutter system of this invention has the quadruple advantage of being easy to install, being clog resistant, being self cleaning, and being without visible slope. Ease of installation is accomplished by modular sections made up of box, gutter and louver rack. These are simply installed level, using the fascia board as a guide as well as a support. A modular section may be installed fully assembled, with preset slope and leader funnel with cleaning water connections--or, at the option of the installer, may be mounted in a two step procedure, first the support box and then the gutter and louver rack. Clog resistance is provided by an integral top grating which interdicts most leaves and twigs as well as the occasional tennis ball. These larger items tend to provide the framework for clogs. The smooth rounded cross section of the bottom of the inner gutter also tends to resist clogging.

  • Patent number: 5725773
    Abstract: An apparatus and a method are provided for collecting samples of used dialysate during hemodialysis treatments. A fluid sample is branched off from the main flow of used dialysate into a sample receiving container. The branching off of the sample flow, i.e. withdrawal of the fluid sample, is either time- or volume-controlled so that during the course of a dialysis treatment a predetermined number of fluid samples are withdrawn, whereby the total sample volume has a prescribed ratio relative to the total volume of used dialysate. The recirculation and sample withdrawal conduit is selectively attachable to the sample receiving container for sample collection, or to the inlet of the hemodialysis device to form a recirculation loop for a disinfection cycle. A disinfectant cartridge can be interposed between the recirculation conduit and the hemodialysis device inlet.

  • Patent number: RE36925
    Abstract: When an object of treatment is subjected to, for example, a gas treatment in an airtight chamber, reaction products adhere to the inner wall surface of the chamber, an object holder therein, and the corner portions of the chamber. When a cleaning medium is injected into the chamber, according to the present invention, the reaction products are dissolved in the cleaning medium by hydrolysis. Thereafter, the cleaning medium is discharged from the chamber. Then, the chamber is heated and evacuated, so that water vapor is discharged to provide a predetermined degree of vacuum, whereupon the treatment can be started anew. Therefore, a wiping operation can be omitted. Moreover, the reaction products remaining at the corner portions of the chamber can be removed without forming a source of polluted particles, so that the necessity of overhauling can be obviated. Thus, fully automatic cleaning, so to speak, can be effected, and the chamber need not be open to the atmosphere, so that the throughput can be improved.
