  • Patent number: 6579842
    Abstract: A method of delivering a benefit agent to fabric for exerting a pre-determined activity, wherein the fabric is pre-treated with a multi-specific binding molecule which has a high binding affinity to the fabric through one specificity and is capable of binding to the benefit agent through another specificity, followed by contacting the pre-treated fabric with the benefit agent, to enhance the pre-determined activity to the fabric. Preferably, the binding molecule is an antibody or fragment thereof, or a fusion protein comprising a cellulose binding domain and a domain having a high binding affinity to another ligand which is directed to said benefit agent. The method is useful for example for stain removal, perfume delivery, and treating collars and cuffs for wear.

  • Patent number: 6368033
    Abstract: A portable electric right-angle plunge router (10) is disclosed which has a pair of laterally spaced apart bases (13, 14), two pair of laterally spaced apart columns (12) and a motor housing assembly (11). The bases (13, 14) have planar work engaging surfaces (15). Affixed to the bases (13, 14) are the laterally spaced apart columns (12) which extend perpendicularly to the work engaging surfaces (15). The motor housing assembly (11) has a central axis which is parallel to the work surface and is mounted on the laterally spaced apart columns (12) to allow the housing assembly to move vertically toward and away from the bases. Laterally space apart column guides (17) affixed to the housing (11) are aligned and sized to slidingly engage the columns (12). A handle is formed in the housing (11) between the front and rear column guides (17). A drive motor affixed in the housing has an armature shaft which is rotatable about an axis being substantially the horizontal axis of the housing (11).

  • Publication number: 20010039250
    Abstract: There is provided a method of delivering a benefit agent to a whereby a benefit agent is first loaded to a surface and subsequently unloaded and transferred and delivered to a second surface. More in particular, the benefit agent is first loaded onto a garment during a laundering process, and subsequently delivered to another surface. The benefit agents can be fragrance agents, perfumes, color enhancers, fabric softening agents, polymeric lubricants, photoprotective agents, latexes, resins, dye fixative agents, encapsulated materials, antioxidants, insecticides, soil repelling agents, soil release agents, and cellulose fibers.

  • Publication number: 20010034314
    Abstract: There is provided a method of delivering a benefit agent to a selected area of a fabric for exerting a predetermined activity, wherein the area is pre-treated with a multi-specific binding molecule which has a high binding affinity to said area through one specificity and is capable of binding to said benefit agent through another specificity, followed by contacting said pre-treated area with said benefit agent, to enhance said pre-determined activity to said area. Preferably, the binding molecule is an antibody or fragment thereof, or a fusion protein comprising a cellulose binding domain and a domain having a high binding affinity to another ligand which is directed to said benefit agent.

  • Patent number: 5721560
    Abstract: A method for controlling a field emission display to reduce emission to grid during turn on and turn off is provided. A field emission display (FED) includes emitter sites formed on a baseplate; a grid for controlling electron emission from the emitter sites; a display screen for collecting electrons to form an image and a power supply. In order to reduce emission to grid during turn on, the display screen is enabled by the power supply prior to enabling of the emitter sites. An anode-baseplate voltage differential is thus established prior to electron emission. For turn on, the method includes varying the capacitances of the control circuits for the display screen and grid such that a time constant (RC) for the grid is larger than a time constant (RC) for the display screen. Alternately the method of the invention can be implemented during turn on using software, using time delay circuit components, or using an emitter site control circuit to control electron flow to the emitter sites.
