Abstract: A drying cylinder (A) is mounted for rotation about its central axis (44). A burner assembly (B) oxidizes fuel interior to the shell, generally along the central axis. A recirculating fan (C) urges the hot combustion gases from the burner into a nozzle box assembly (D). The nozzle box assembly includes a plurality of peripherally spaced, longitudinally extending boxes (80) which have an array of nozzles (82) therein. The nozzles direct jets of hot combustion gases against an interior surface of a cylindrical dryer shell (30) for transferring heat thereto. Hot combustion gases which have impinged upon the shell are recirculated through passages (84) and are in part reheated by the burner and in part discharged through an exhaust aperture (90) and an exhaust duct (92). In one embodiment, the direct fired dryer is mounted in one of the dryer sections of a Fourdrinier paper production line. In another embodiment, particulates and other non-sheet materials are applied to the dryer shell, dried as the dryer shell rotates, and the dried materials are removed.

Abstract: A laser arrangement in an optical communication system has a semiconductor laser (1) which includes an optical waveguide (4) whose end surfaces (5,8) have reflection-inhibiting coatings. The end surfaces (5, 8) are connected to a respective first connection (7, 10) of a first (2) and a second (3) directional coupler switch. Each of the directional coupler switches (2,3) have a second connection (13, 14), which is provided with mirrors (15, 16), and a third connection (11, 12), which is connected to a respective optical fibre (17, 18) in the communication system. In a receiving and amplifying state, an incoming light signal (P1) is coupled by the first coupler switch (2) to the laser diode (1), where the signal is amplified by a drive current (I) and detected (24). The amplified signal (P2) is coupled to the outgoing fibre (18) by the second coupler switch (3). In a light generating state, the first directional coupler switch (2) is in its cross state and the second directional coupler switch (3) is in an intermediate state, between its two terminal states, so that the mirrors (15, 16) define a cavity which includes the laser diode (1). By modulating the drive current (I) around the lasering threshold, a signal can be transmitted on the outgoing fibre (18). Alternatively, the laser arrangement can be modulated with the aid of the directional coupler switches (2, 3) for the purpose of transmitting the signal.

Abstract: A porous ceramic material composed of a sintered porous body of a calcium phosphate compound is described. A multiplicity of capillary void paths having a diameter of 1 to 30  mu m and a multiplicity of pores having a diameter of 1 to 600  mu m are formed in the sintered porous body. At least part of the pores are connected to the exterior space of the sintered porous body through at least a part of the capillary voids. The porous ceramic material is valuable as a medical material, e.g., a substitute or prosthesis for bone or dental root, and also an electronic material and a genetic engineering material. When the porous ceramic material is embedded in a bone defect of human or animals, osteolytic cells, osteoblasts, erythrocytes and body fluid are selectively allowed to intrude through the porous ceramic material while almost no intrusion of osteoclasts and collagen fibers is allowed. Accordingly, the porous ceramic material can be utilized for inducing new-born bone, controlling resorption of bone with age, remedying bone defects.
