Appl. No.:

09/101138

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

B41J 2165

US Classification:

347 31, 347 29

Abstract:

A foam-filled cap sealing ink-ejecting nozzles of an inkjet printhead in a printing mechanism has a two-layer structure, with an outer skin layer of an elastomer, and a second foam core layer inside the skin. The skin defines a sealing lip that surrounds the nozzles when the cap is in a sealing position to avoid unnecessary drying of the ink. The skin has an interior surface that defines a cavity under the sealing lip. The foam core, located within the cavity, may be formed by expanding a foam preform or by injecting raw foam into the cavity. An insert may be molded into the cap structure for use in mounting the cap in the printing mechanism. An optional backing layer molded to the structure is used to attach a vent basin to the cap. A method of constructing this cap, and a printing mechanism having this cap, are also described.

Abstract:

A method of manufacturing a low-moisture penetrating decorative floor surface. The completed floor surface has an appearance of a solid granite slab floor with greater durability. The floor surface has a smooth, flat appearance and can be manufactured in different shapes. The floor surface may be formed over a wood or concrete sub-floor and includes a self-leveling, cementous, low moisture penetrating material to which suitable colorants may be added. The cementous material comprises a topping and silicate-based sealant mixture that is mixed together and poured and leveled over the sub-floor to a desired height. Flakes of contrasting material is then sprinkled over the top surface of the mixture to create a decorative appearance. After drying, the surface is finely ground to a smooth finish. A coat of silicate-based sealant is then applied to the surface that penetrates the porous surface to create a low moisture emitting surface The surface is then ground to a fine surface and rinsed.

US Classification:

347 28

Abstract:

A wet-wiping printhead cleaning system including a source of treatment fluid further including a treatment fluid reservoir and a treatment fluid transfer element adapted to transfer treatment fluid from the reservoir to at least one of the two elements involved in wiping the printhead, the two such elements consisting of the printhead and the wiper, the transfer element thereby acts as an applicator placing treatment fluid onto said at least one element, the source of treatment fluid not contacting said one element directly, and the treatment fluid then is available to assist in cleaning the printhead as it is wiped by the wiper, removing accumulated dried ink solids and other debris, the treatment fluid lubricating the wiper so as to lengthen wiper service life and enhance wiping performance, as well as acting to render such accumulations more removable by wiping.

Inventors:

James C. Harvey - Sherwood OR

International Classification:

A61B 106

US Classification:

128 4

Abstract:

A flexible laryngoscope is intended for use with a light source which produces a light beam. The laryngoscope includes a body which has a fibre-optic bundle extending therefrom including a fibre-optic cable having a viewing end and a movable free end. An eyepiece is carried on the body and is optically connected to the viewing end of the fibre-optic bundle. Suitable optics are provided for directing a light beam from the light source to the fibre-optic cable. A directing mechanism is provided and positions the fibre-optic cable at a substantially 90. degree. angle to the eyepiece as the cable extends outwardly from the laryngoscope body. A guide mechanism is provided for controlling the location of the free end of the fibre-optic cable.
