Abstract: A fragrant fibrous structure, such as fabrics, apparels or the like, provided with microcapsules encapsulating a perfume and a resinous binder, preferably a silicone resin, in a weight ratio of 2/1 to 1/5, an add-on amount in the aggregate of said microcapsules and resinous binder being 0.3.about.7.0% based on the weight of the portion to which said microcapsules and resinous binder are adhered, of the fibrous structure. The process for preparing the above fibrous structures comprises applying a treating liquid comprising microcapsules composed of an external wall of a formaldehyde based resin enclosing a perfume and a resinous binder, preferably a low temperature reactive organopolysiloxane prepolymer emulsion, preferably together with a pressure absorbing agent, to at least a part of a fibrous structure and then drying the fibrous structure at a temperature of less than 150.degree. C. to fix said microcapsules on fiber surfaces of the fibrous structure.

Abstract: The disclosed method and apparatus measures radial deviations along the axial length of a work roll with a number of axially spaced displacement detectors and at least three axially spaced motion detectors mounted ona detector mount that moves axially along the roll. A calculator responds to the motion detectors to determine errors in the motion of the mount to correct the output of the detectors and sums the deviators to generate overall deviations.

Abstract: In a system for removing a faulty weft on a loom a mobile weft catcher unit engageable with a weft of an open shed is driven for successive removal of the next and faulty wefts by operation of a controller which generates phased instruction signals in response to detection of abnormal weft insertion.

Abstract: Practice of an auto-repair operation on a loom is automatically prohibited when the frequency of auto-repair operation exceeds a preselected rate in order to avoid production of off-grade cloths otherwise caused by continuously repeated formation of weaving defects.

Abstract: A method of developing latent electrostatic images comprising the steps of stirring a developer containing toner particles and carrier granules to triboelectrically charge the toner particles to a polarity suitable for developing a latent electrostatic image on an image bearing surface, causing the latent electrostatic image on the surface to electrostatically attract toner particles in the stirred developer to convert the latent image to a visible image and replenishing the developer used for the development and containing a reduced quantity of toner particles with toner particles different in triboelectric chargeability (capability of being triboelectrically charged by frictional contact with carrier granules) from the toner particles initially contained in the developer before the development.

Abstract: An electrostatic latent image transfer type copying apparatus which has a photoconductive member, a system for forming an electrostatic latent image on the photoconductive member, an image transfer system for conducting transfer material having an insulating dielectric layer coated over an electrically conductive layer into contact with the photoconductive member for transferring the latent image onto said transfer material, a transporter for the transfer material to transport it along a predetermined path to the image transfer system, a member such as a relatively sharp edge member like a cutter provided along the path and below which the insulating dielectric layer side of the transfer material passes, and an insulating member provided adjacent the sharp edge member for preventing the surface of transfer material from contacting the sharp edge member as the transfer material is transported, whereby the contact of the sharp edge member with the surface of transfer material which causes frictional charging on

Abstract: A liquid type developing apparatus includes a developing liquid chamber containing a developing liquid comprised of toner and an organic solution. A recording sheet having an electrostatic latent image on its surface passes between a pair of upper and lower electrically conductive electrode members arranged so that at least one of such members contacts the developing liquid. An electric power source is connected to one of the electrode members for impressing a bias voltage thereto, such one member being arranged in non-contacting relationship with the chamber, and the other of such members being arranged in electrically conductive relationship with the tank, whereby any leakage of the impressed voltage due to attraction of the toner to the members, the tank or to bearings provided for the members, is substantially avoided.
