Abstract: A tape printer cassette, bearing a film tape and ink ribbon on spools therein, maintains the film tape in a feed path defined by an outer wall and a partition and the ink ribbon in a feed path defined by the partition and an inner wall. The inner wall and the partition are set to be substantially the same height as the ink ribbon and higher than the outer wall. When the ink ribbon is wider than the film tape, an unused portion of the ink ribbon remains after printing; regulating members spaced by the width of the film tape, downstream of the printing region, keep the film tape in the center of the ribbon so that the unused portion remains and so that the ink ribbon cannot proceed along the film tape feed path past the regulating members. When an adhesive backing is also provided on a spool in the cassette, regulating members align the film tape and adhesive backing at a feed capstan so that they are not displaced relative to each other when adhered.

Abstract: A rope traction device used as a winding instrument for a moving scaffold and other construction, loading and unloading and conveying machines, includes a sheave which is rotated by a motor through a speed reduction gear and around which a part of a traction rope is wound, and is movable along the rope by rotating the sheave. The sheave is provided with a rope groove formed by a pair of parallel and planar side plates substantially along the entire circumference of the sheave for receiving a part of the rope therein and resiliently pressing the rope on its side portions. The rope traction device includes an improved brake system according to which slots elongated in the circumferential direction are formed in each clutch member and each slot has a greater depth axially in the central portion thereof than in other portions.

Abstract: A rope traction device has a sheave which is driven and rotated to cause a traction rope to be wound on the sheave and thereby moves along the traction rope. The rope traction device includes a pair of annular side plates made of an elastic material and provided at sides of the sheave in such a manner that the interval between the inner surfaces of the side plates is made smaller than the diameter of the rope by a predetermined value and the side plates are secured to the sides of the sheave by means of boltheads of bolts arranged alternately in the circumferential direction of the sheave. The side plates may alternately be secured to the sides of the sheave by means of boltheads of bolts and nuts positioned at opposite positions in the circumferential direction of the sheave.

Abstract: A work apparatus for a work on a wall surface of a structure, e.g., a building, comprises rail supports secured fixedly to an upper end portion of a structure, upper provisional horizontal rails supported provisionally on these rail supports, lower provisional horizontal rails mounted provisionally on a lower portion of a wall surface of the structure in parallel with the upper provisional horizontal rails, upper horizontally running trolleys mounted slidably on the upper provisional horizontal rails and connected to one another, a working platform, e.g.

Abstract: Disclosed is a finish coating method for forming a finish coat, comprising the steps of applying to a substrate a base coating composition containing a pigment and applying a clear top coating composition to the coated surface, the method being characterized in that the clear top coating composition is a curable one comprising predominantly a nonaqueous dispersion of a polymer of radically polymerizable monomer, the dispersion being prepared by polymerization of the radically polymerizable monomer in an organic solvent in which the monomer is soluble and in which the polymer produced from the monomer is insoluble and in the presence of a fluoroolefin polymer as a dispersion stabilizer which is soluble in the organic solvent and which has a weight-average molecular weight of about 5,000 to about 120,000 and a fluorine content of about 1 to about 60% by weight.

Abstract: Disclosed is a coating method for forming a metallic coat, comprising the steps of applying to a substrate a base coating composition containing a metallic pigment and applying a clear top coating composition to the coated surface, the method being characterized in that the clear top coating composition is a curable one comprising as a main component a nonaqueous dispersion of a polymer of a radically polymerizable monomer, said dispersion containing as a dispersion stabilizer a fluorine-containing copolymer comprising a hydroxyl group-containing monomer and a perfluoroalkyl group-containing acrylic or methacrylic monomer represented by the following formula (1) ##STR1## wherein R is a hydrogen atom or a methyl group, n is an integer of 1 to 11 and R.sub.f is a straight chain or branched chain perfluoroalkyl group having 1 to 21 carbon atoms.

Abstract: A device for horizontally moving an apparatus such as a gondola working at a high location such as a wall surface of a building comprises a mounting frame fixedly provided on the upper end portion of a structure and having a vertically extending rotary shaft receiving portion, a rail supporting member having a rotary shaft received in the rotary shaft receiving portion and also having an arm extending substantially normally from the rotary shaft and including a rail supporting portion at the foremost end thereof, a horizontally extending rail disposed detachably on the rail supporting portion, a rail pivoting device associated with the rail supporting portion and the rail for pivoting the rail when the rotation shaft is rotated, and a trolley mounted on the rail for suspending the apparatus working at a high location.

Abstract: A rope locking device for stopping an abnormal descent of an ascending and descending apparatus such as a gondola used for a construction work. The device comprises two separate cases. One of the cases contains a rope clamping member formed on one side thereof with a groove in which one side of a rope can be engaged, a rope clamping member drive for displacing the rope clamping member between a first position in which the rope clamping member is spaced from the rope and a second position in which the rope clamping member is pressed against the rope, an energizing member for energizing the rope clamping member to move from the first position to the second position, a lock device for holding the rope clamping member in the first position against the energizing force and a lock release device for releasing locking of the rope clamping member by detecting a relative running speed of the rope and releasing the lock device when the running speed of the rope has exceeded a predetermined speed.

Abstract: A rope traction apparatus includes a sheave around which an intermediate length of traction rope extends. One run of the rope which is located on one side of the sheave provides a traction run while the run located on the other side thereof provides a free run. The sheave is firmly mounted on a drive shaft which is rotatably mounted on a frame assembly. The frame assembly is provided with an operating member which is rotatably mounted on a support shaft which extends parallel to the drive shaft. The operating member has its opposite ends located adjacent to the periphery of the sheave and each carry a roller having an axis which extends parallel to the drive shaft. One of the rollers is located to engage the traction run of the rope to cause an angular movement of the operating member in response to the tension therein. The other roller is located close to the sheave to hold the traction rope in a groove formed in the sheave as a result of the angular momentum applied to the operating member.
