Abstract: The present invention concerns easily removable treatment tubes from fabric treatment apparatuses in order to facilitate replacement of such rolls for treatment modification, cleaning, disposal, or any other desirable purposes. Such treatment tubes are generally hollow and may be coated with any standard fabric treatment surface, including sandpaper, diamond grit, wires, brushes, and the like. The ability to easily remove and dispose of such treatment tubes thus provides a significant cost advantage to the manufacturer.

Abstract: A voice controlled compact computer device (10) is provided in which speech is substituted for keyboard entry of text and for control signals otherwise input by keyboard or pointing device. Spoken words and commands are recognized by an interpreter and displayed in real time to only one eye, using a compact folded display having at least one mirror with negative curvature (16). In another embodiment, a second mirrored display (38) is used to project an independent image to the other eye.

Abstract: A method for continuous conditioning of a rubber blanket such as the type used on compressive shrinkage apparatus is described. The blanket includes an inner bearing surface defining a bearing face and an outer surface defining a web-contacting face. The web-contacting face is contacted under pressure with an abrasive conditioning roll while the blanket is in its regular, web treating operation. The blanket working face can thus be continuously conditioned without the need for lengthy machine stops. In this way, the conventional grinding and cleaning operations can be minimized or eliminated.

Abstract: The inventive method provides highly desirable hand to various different types of fabrics through the initial immobilization of individual fibers within target fabrics and subsequent treatment through abrasion, sanding, or napping of at least a portion of the target fabric. Such a procedure includes “nicking” the immobilized fibers thereby permitting the fibers to produce a substantially balanced strength of the target fabric in the fill and warp directions while also providing the same degree of hand improvements as obtained with previous methods. Furthermore, this process also provides the unexpected improvement of non-pilling to synthetic fibers as the “nicking” of the immobilized fibers results in the lack of unraveling of fibers and thus the near impossibility of such fibers balling together to form unwanted pills on the fabric surface. Fabrics treated by this process are also contemplated within this invention.

Abstract: A process for angularly sueding a textile web containing fill and warp yarns with the steps of: supplying the web, controlling the tension of the web, engaging the web with at least one abrasive covered treatment roll disposed at an abrasion angle, rotating the treatment roll at a surface speed different from that of the web, and taking up the supplied web. A preferred embodiment comprises a pair of spaced treatment rolls disposed at an abrasion angle, and rotating in opposite directions relative to the web. The related apparatus for this specific process is also provided.

Abstract: A process for abrading fabrics to produce a sueded hand is provided. In particular, the process is directed to the sueding of cotton containing fabrics both before and after mercerization, to produce a unique combination of hand and retained fabric strength. Fabrics treated by this process are also contemplated within the scope of this invention.

Abstract: The various embodiments of the invention are directed to manufacture of safety razor heads (1) having an intrinsically fenced unitary blade (7) oriented at a high slicing angle to the shaving direction. The unitary blade comprises a plurality of short blade edges (22) in a spaced relationship across the width of the blade, bounded by leading (19) and trailing guards (8), and oriented at an angle greater than 30 degrees, resulting in enhanced cutting action, improved lubricant and debris flow, and longer life.

Abstract: A process for treatment of a web by means of impingement by high velocity gaseous fluid is provided. The process constitutes the provision of a web to a treatment zone at a tension of between about 1 and about 5 pounds force per linear inch of web width. In the treatment zone the web is subjected to the imposition of high velocity gaseous fluid substantially tangential to the web and in the direction of travel by the web through the treatment zone, such that a series of saw-tooth waves are formed in and move along the web in the direction of travel by the web. An apparatus for carrying out the process is also provided.

Each segment (70) is hinged to adjacent segment to allow convex and concave bending. Alternatively, blade assemblies (15) may be joined together by means of an elastic ligature (74). Two point mounting to a handle (12) allows convex and concave bending. Mounting may be facilitated with magnetic cups (138) attached to the handle, and mating buttons (132) attached to the read of the razor head.

Abstract: A process for treatment of a web by means of impingement by high velocity gaseous fluid is provided. The process constitutes the provision of a web to two separate treatment zones. In the first treatment zone the web is subjected to the imposition of high velocity gaseous fluid substantially tangential to the web and in the opposite direction of travel by the web through the treatment zone, such that a series of saw-tooth waves are formed in and move along the web in the opposite direction of travel by the web. In the second conditioning zone, the same type imposition of high velocity gaseous fluid to the web occurs with the gas streams and the resultant saw-tooth waves forced in the same direction as the travel of the web. The two zones are separated by an area of high tension on the web. An apparatus for carrying out the process is also provided.

Abstract: A method and apparatus for loosening, cutting, and abrading a web of textile fabric having spun yarns containing wrapper fibers. The textile fabric web is directed under high tension around pairs of rotatable, small diameter tubes coated with abrasive particles. Abrasive particles are preferably rounded (nonfaceted) tungsten carbide particles. The tubes (rolls) are rotated at differing speeds in relation to the fabric web speed through the apparatus. Preferably, the first, regressive roll rotates at a speed slower than the web speed and the second, progressive roll rotates at a faster such speed. Such a process and apparatus provide improved conditioning and napping of a fabric web as well as a quicker, more efficient method of performing such fabric treatment.

The fibers are at least partially coated with a powder which exhibits dilatant properties when hit by a moving article. Such powder is preferably nonlaminar in particle geometry and is more preferably characterized by fractal dimensionality. Among the contemplated uses for such fabric are automotive airbags and turbine engine safety wrappings.
