Patent number: 5055375Abstract: A method of forming an image which comprises subjecting an image-forming material comprised of a substrate and a photosensitive layer containing a dye and/or a pigment and a photopolymerizable compound and disposed on the substrate to an image-exposure, thereby to allow the exposure to cause a difference of adhesion between an exposed portion and non-exposed portion in the photosensitive layer, and transferring the image to an image receptor on the basis of the difference of adhesion; wherein the photosensitive layer of the exposed image-forming material and the image receptor are allowed to face each other and directed into the nip between two rollers consisting of an elastic roller and a metallic roller having a surface temperature of between 50.degree. C. and 150.degree. C.Type: GrantFiled: January 4, 1991Date of Patent: October 8, 1991Assignee: Toyo Ink Manufacturing Co., Ltd.Inventors: Masaaki Matsuo, Masujiro Sumita, Isao Hosoi, Hirohumi Aoki, Masaru Ohta

Patent number: 4840224Abstract: A heat energy transfer device has an enclosure defining a closed cavity and including an outer face to be heated or cooled. A heat transfer medium is contained in the cavity. The device has a first capillary arrangement disposed in the cavity for advancing the heat transfer medium in the liquid phase in a first direction parallel to the outer face of the enclosure and a second capillary arrangement disposed in the cavity for advancing the heat transfer medium in the liquid phase in a second direction parallel to the outer face of the enclosure. The first and second directions are non-parallel to one another.Type: GrantFiled: April 28, 1988Date of Patent: June 20, 1989Assignee: Sig Schweizerische Industrie-GesellschaftInventor: Claudius R. Dietzsch

Patent number: 4825041Abstract: A thermally developing apparatus for a light and pressure sensitive material. The exposed material is inserted between a rotating heated roller and an endless belt wrapped partially around the roller. Additionally, a temperature sensor detects abnormally high temperatures and, as a result, removes the material from the heated roller.Type: GrantFiled: December 18, 1986Date of Patent: April 25, 1989Assignee: Fuji Photo Film Co., Ltd.Inventors: Akihiko Nagumo, Minoru Ishikawa

Patent number: 4695704Abstract: A curling iron includes an elongated heating element attached at one end to a handle and having an outer circular peripheral surface provided with a plurality of generally arcuately spaced, radially open grooves extending longitudinally on the outer peripheral surface of the heating element between the first end adjacent the handle and second free end, with the grooves being axially open at the second end. Plurality of bars supporting hair grooming members are slidingly removably engaged in the grooves through the open ends thereof in heat exchange relation with the heating element. An auxiliary handle is attached to the second end of the heating element for preventing removal of the bars from the grooves, there being free, unlimited, bidirectional relative rotation between the auxiliary handle and the heating element.Type: GrantFiled: September 27, 1984Date of Patent: September 22, 1987Inventor: Matthew L. Andis

Patent number: 4629867Abstract: There is disclosed a heated roll for the thermal treatment of formed products. It includes a driven hollow shaft and a hollow roll body of a circular-ring-shaped cross section and closed on all sides to accommodate a heat transfer medium. Power supply lines for heating elements as well as electric wires of temperature probes are led through the hollow shaft. In order to provide a heated roll to be used without problems both in the low-temperature range and in the high-temperature range up to about 600.degree. C. and to reach a uniform temperature profile over the total operation surface of the roll outer shell and a long service life of the heat transfer medium, without excessive temperature prevailing at the bearings of the driving shaft, and to provide for an easy repair, the hollow shaft is connected with the roll body by a hub. One or several saline compound(s) or (a) low-melting metal(s) or metal alloy(s) are contained in the interior of the hollow roll body.Type: GrantFiled: March 25, 1985Date of Patent: December 16, 1986Assignee: Lenzing AktiengesellschaftInventors: Josef Baumgartinger, Ernst Rauch, Haio Harms, Adalbert Wimmer

Patent number: 4627176Abstract: The outer side surface of the drying cylinder (1) is delimited by a plurality of coaxial rims (2) having the same radius, arranged side by side and separated two by two by an axial space (7), and made of a good heat-conducting material. Each rim (2) is heated and cooled independently from the others by a heating member (8) and a cooling member (11) housed into a subrim (3) surrounding by the rim (2). The heating is provided for example by an electric resistance and the cooling by circulation of cold water, the control being provided by means of remote controlled relays (10). Each rim (2) is rotationally integral with a hub (5) wedged to a drive shaft (6). A comb (26) having teeth (27) engaged into the spaces (7) avoids the winding of material around the cylinder (1) which is in depression conditions in order to favor the heat exchanges by suction of the material against the cylinder (1). Applications to the equipment of dry ends and post dry ends of paper-, cardboard- or other web material machines.Type: GrantFiled: June 24, 1985Date of Patent: December 9, 1986Assignee: Chleq Frote et CieInventor: Francois Brieu

Patent number: 4538052Abstract: A fixing roller for a fixing unit for a copying machine has a heater disposed within an aluminum cylinder. A pair of stainless steel, U-shaped plates, which have holes cut in their bottoms, are fitted into opposite end portions of the cylinder to hold the heater and to utilize the heat generated thereby. A pair of bearings, which have outer races made of heat-resistant resin, are fitted into the opposite end portions of the cylinder under pressure to support the cylinder so that the outer races and the cylinder turn as one unit.Type: GrantFiled: July 30, 1982Date of Patent: August 27, 1985Assignee: Fuji Xerox Co., Ltd.Inventors: Tetsu Asanuma, Satoru Inagaki

Patent number: 4535230Abstract: The invention concerns variable contour rollers for use in calendering or pressing devices, printing presses and like applications. The rollers include an external element of cylindrical form, for example of cast iron, and in their interior a number of transverse elements which can be made to expand radially by heating. More or less substantial radial expansion provokes directly or indirectly a change in the profile of the exterior generally cylindrical working surface. The interior of the roller may be a shaft carrying heating elements and which is fixed or rotates with the external working surface.Type: GrantFiled: April 9, 1982Date of Patent: August 13, 1985Assignee: Chleg Frote et CieInventor: Francois M.
