Abstract: A process is provided for manufacturing a high quality cloth having a width of 150 cm or any width in which likelihood of occurrence of defects such as color shading, rub marks, wrinkles and creases due to fabric dyeing method is eliminated and color fastness is enhanced.A process for manufacturing a woven or knit fabric using yarn dyed silk comprises the steps of dyeing (step 3) sericin which covers the periphery of silk fibers and fibroin which is located inside thereof into the same color; making yarn dyed silk (step 4, 5) by doubling and twisting the dyed silk fibers; making a cloth (step 6) by weaving or knitting the yarn dyed silk; swelling (step 7) the yarn dyed silk which constitutes the cloth by dipping the cloth into hot water in a tub; and decomposing (step 8) sericin of the yarn dyed silk of the cloth with an enzyme in hot water in a tub.

Abstract: The invention discloses a wrist-device which comprises a first module (1) such as a personal computer and a second module (2) consisting of a mobile telephone or a wireless telephone terminal which are coupled by means of elements (15) in a bracelet configuration for holding the device to the forearm of the user, and wherein windows (12) are provided in said modules for the passage of electronic connection buses (13) between said modules (1 and 2).

Abstract: A nonwoven media wiping material is provided by a thermal point bonding process which comprises the steps of combining a carded web of predominantly textile-length thermoplastic fibers having a higher melting temperature and a polymeric sheet having a lower melting temperature, and applying heat and pressure to the combination of film and fiber layers through thermal calendering. The polymeric sheet melts and becomes bonded to the carded fibers in discrete points to provide a soft and lofty outer media contacting finish.

Abstract: A pants having frayable leg bottoms is provided by provision of at least one circumferential thread stitching proximate each leg bottom. The circumferential thread stitching provides a defined boundary for fraying and cutting the leg bottom to a selected length. The pant legs are cut below the stitching line to define the fabric area for fraying in the pant legs. Fraying in the legs is then provided by separation of yarns at cut bottoms in normal wear and laundering of the pants. In a preferred embodiment, the pant legs include multiple circumferential double needle top stitching rows of thread which are spaced apart from the leg bottoms.

Abstract: The present invention provides a hot air welding apparatus that provides accurate and repeatable control of the drive wheel speed. To afford very precise control of the speed and relative rotation of the drive wheels at all times during the welding process, the present invention is provided with a computer control system and two high torque stepper motors, one for each drive wheel. The computer control system allows the speed and position of the drive wheels to be regulated with a very high accuracy. The computer control system allows the drive wheel settings to be adjusted while the seam is being welded and further includes an automatic ramp capability, a repeat mode, and a test strip mode. Further, the computer control system is capable of controlling the temperature of the air used in the welding process.

Abstract: A method wherein waste cellulosic material is used as an alternative fiber source during chemical pulping to replace a fraction of the wood chips. The waste cellulosic material is fed to the digester along with wood chips. The waste cellulosic material need not be repulped or slurried prior to digestion. The wood chips may be any species of hardwood or softwood. Normal chemical pulping charges, temperatures and cooking times applied in the case of 100% wood chip pulping may be used for the co-pulping of waste cellulosic material and wood chips. Thereafter, the pulp is processed as usual for chemical pulping, including the steps of blowing the digester, washing and thickening the brown stock, and bleaching the brown stock under the normal conditions used for the component co-pulped with the waste cellulosic material. Further screening or cleaning steps may be required to remove debris from waste cellulosic material.

Abstract: A switching power supply using SEPIC topology with an input and output circuit (12, 14). The input circuit (12) contains two inductance coils (D1.1) and (D1.2). To improve power supply and control properties, the second inductance coil (D1.2) is magnetically coupled to the first inductance coil (D1.1), in such a way that a value (IS), proportional to current (IS), measured in the second inductance coil (D1.2), can be supplied to a current regulator (KI) as an actual value. A computer unit (RG') contains an input (A) for a voltage difference (UF) from output voltage (UA) and reference voltage (USOLL), an input (B) for a sinusoidal input voltage (UE), and an additional input (C) for the peak value (UES) or a phased-shifted voltage (k.times.UES) of the input voltage as a direct voltage reading, whereby a signalD=A.times.B/C=UF.times.UE/k.times.UESis produced at output (52').

Abstract: A suede-like micro-fibril finish is imparted to fibrillatable cellulosic materials by open width hydraulic treatment. Additional enhancement of the fabric finish is obtained by post hydraulic enzyme and wet processing treatments. Fluid treated fabrics of the invention are characterized by substantially uniform fibrillation of fibers within the fabric body and surface areas.

Abstract: A system for monitoring of a product quality variable of a moving web produced by associated equipment defines cross-direction (CD) data increments across a width of the web and machine direction (MD) data increments over a running length of the web, and takes CD/MD measurements of the selected variable in order to fill the corresponding CD/MD measurement data boxes and generate a time-dependent two-dimensional array mapping representing the moving web. In the preferred system, the CD data increments are divided across the width of the web, and the MD data increments are time-divided intervals of the time period of an element of the production equipment, so as to produce a time-synchronous array mapping which shows the impact of the periodicity of the machine element on the product quality variable.

Abstract: A deepithelialized skin cell diffusion system which can be used to select topical gel and cream formulations containing human other wound healing promoters such as plasma fibronectin. The formulations provide slow release and increased contact time of fibronectin or other wound healing promoters to the wound site leading to its effective absorption.

Abstract: Topical gel and cream formulations containing human plasma fibronectin and other wound healing promoters are used for the healing of cutaneous wounds. The formulations provide slow release and increased contact time of fibronectin and of other wound healing promoters to the wound site leading to the effective absorption of the promoters.
