  • Patent number: 6653377
    Abstract: An economical and reliable system for the contained transfer of particulates by means of a series of transfer containers facilitates the particulate transfer without either exposure of the operating personnel and the environment to the particulate, or environmental contamination of the particulate itself. The system employs a multiple o-ring canister assembly which can be attached to either the discharging port or charging port of a piece of processing equipment. The canister has a series of circumferential o-ring grooves which allows the attachment of a series of individual transfer containers. In a charging mode, once the particulate is charged to the processing equipment, a first transfer container is collapsed and a second transfer container is placed in the next o-ring groove, thereby containing the remaining contaminated section of the first transfer container. The first transfer container is removed through a bag-out sleeve which is an integral part of the second transfer container.

  • Patent number: 6207265
    Abstract: A water soluble, non-ionic masking agent is used in the manufacture of printed circuit boards. The masking agent masks portions of the circuit board to prevent adhesion of solder, flux and the like. The masking agent includes a water soluble non-ionic binder resin, a cellulosic non-ionic filler, a non-ionic surfactant, at least one non-ionic associative thickener, and deionized water. The masking agent material is readily removed from the circuit board after manufacture and does not render further wash water processing ineffective. The masking agent is non-ionic, and thus does not agglomerate or clump downstream ion-exchange or filtration media.

  • Patent number: 5556572
    Abstract: There are herein disclosed a rubber composition for cleaning a mold which comprises 100 parts by weight of a natural rubber and/or a synthetic rubber, 2 to 30 parts by weight of an amino-alcohol salt in terms of an amino-alcohol content, 5 to 50 parts by weight of a glycol, 30 to 90 parts by weight of an adsorbent and 0.5 to 10 parts by weight of an organic peroxide, and a method for cleaning the mold by the use of this rubber composition.Since the amino-alcohol is fixed as the salt, the generation of ammonia odor at the time of kneading or at room temperature can be prevented to improve a working environment, and the volatilization of the amino-alcohol can be inhibited, whereby a mold cleaning effect can be maintained even after the lapse of a long time.

  • Patent number: RE40840
    Abstract: An economical and reliable system for the contained transfer of particulates by means of a series of transfer containers facilitates the particulate transfer without either exposure of the operating personnel and the environment to the particulate, or environmental contamination of the particulate itself. The system employs a multiple o-ring canister assembly which can be attached to either the discharging port or charging port of a piece of processing equipment. The canister has a series of circumferential o-ring grooves which allows the attachment of a series of individual transfer containers. In a charging mode, once the particulate is charged to the processing equipment, a first transfer container is collapsed and a second transfer container is placed in the next o-ring groove, thereby containing the remaining contaminated section of the first transfer container. The first transfer container is removed through a bag-out sleeve which is an integral part of the second transfer container.
