Abstract: The invention comprises a continuous hot rolling method in which a rear end portion of a preceding metal block and a fore end portion of a succeeding metal block are cut and the metal blocks are joined to each other by heating and pressing followed by a finish rolling. A region of each metal block is restrained from a clamping position to the end portion thereof in order to prevent a change in level of the metal blocks in heating and pressing the piece. The end portions of the metal blocks can be thus prevented from deformation.
Abstract: A tilt lock device 10 comprises a piston 13 having a piston rod 14, an inner cylinder 12 defining the piston 13 into an upper oil chamber S1 and a lower oil chamber S2, and an outer cylinder 11 surrounding the inner cylinder 12. A communication passage 34 is formed in the piston 13 for bringing the upper and lower oil chambers S1 and S2 into communication with each other, and an on-off valve 15 capable of being operated from outside is disposed in the communication passage 34 for preventing oil from flowing from the lower oil passage S2 into the upper oil passage S1, and for also serving as a shock absorbing valve which allows oil to flow from the upper oil chamber S1 to the lower oil chamber S2 when a pressure in the upper oil chamber S1 exceeds a set pressure so as to absorb a shock.
Abstract: In a method and a device for controlling the servicing of an aircraft parked at a stand, the servicing is carried out from a plurality of servicing units which are stationarily arranged adjacent to the stand and which each are adapted to supply fuel, water, compressed air, preconditioned air or electric power to the aircraft or to service the toilets of the aircraft. A plurality of local computer units are each disposed in a a servicing unit and have an associated display as well as an associated inputting device. A central computer unit is connected to each of the local computer units and to an information receiver in or in the vicinity of the aircraft. The central computer unit transmits information to the local computer units of the servicing units on the servicing to be carried out. Each of the local computer units records information on the servicing carried out and transmits this information to the central computer unit, which in turn transmits the information to the information receiver.

Abstract: An inverted strut damper includes an external cylinder which has an expanded midsection and a vertically moveable damper tube arranged concentrically within the outer cylinder. The outer cylinder and tube arrangement form a lubricating oil supply reservoir. Disposed at a top and a bottom of the outer cylinder is a respective oil seal and bearing arrangement. The upper bearing is adjacent to the lubricating oil reservoir and upon upper movement of the damper tube, oil is supplied to the upper bearings and seal.
Abstract: An elastic water-permeable polymeric concrete composition, a formulation method therefor, an elastic water-permeable polymeric concrete structure using the composition, and a method for constructing the structure. The polymeric concrete composition is formulated by integrating a rubber powder ground from waste tires or waste rubber and an aggregate using a polymeric binder, and if required, by adding a pigment and aromatic capsules capable of providing remedial and psychological effects. The polymeric concrete structure manufactured using such polymeric concrete composition has appropriate elasticity, water permeability, strength and a pleasant aroma. Thus, the polymeric concrete composition is useful for paving a footpath, a roadway, a bikeway, a railway crossing, a parking lot, a stadium, a racing track, a landing strip, etc., and as a material for civil engineering and constructions such as blocks, tile sound-absorbing plates, soundproofing plates, soundproofing walls and retaining walls.
Abstract: An-line trap assembly is disclosed for preventing the drop out of suspended particulant matter within a cooling water flow stream. The in-line trap assembly is provided with a collector tank for gathering debris and a bleed through piping network for creating a continuous flow of cooling water. The continuous flow of cooling water from a supply header to a return header assists in moving the debris into the collector tank where the collected sediments are then removed by a manual or automated blow-down of the in-line trap.
Abstract: A hydraulic hammer having an improved buffer assembly is provided. The hydraulic hammer includes a housing, a top cover plate connected to the upper portion of the housing, a hammer assembly installed in the housing, and a buffer assembly for supporting the hammer assembly, installed between the top cover plate and the hammer assembly, in which the buffer assembly includes a top buffer contacting the upper portion of the hammer assembly and formed of an elastic material for absorbing impact, and a sliding plate is disposed between the top buffer and the top cover plate. The hydraulic hammer reduces the repeated banding stress applied to the hammer assembly.
Abstract: A method of operating a blast furnace enables substantial improvement of gas permeability and liquid permeability for stable operation of the blast furnace, involves packing the core section with solid high strength, carbonaceous blocks prior to ignition of the furnace. The carbon blocks resist wearing and high temperature reaction over very long periods of operating time, greatly stabilizing the furnace. Because of the improved stabilization, gas permeability and liquid permeability, a low grade solid reducing agent can be substituted for a quantity of the high quality coke normally used for operating the blast furnace and furthermore enables injection of pulverized coal at a rate of at least 200 Kg/ton-pig.
Abstract: An apparatus for airing grains stored in bulk on a floor of a depot, including a tunnel comprising a duct made of half cylindrical shaped corrugated sheets. The corrugations are approximately sine-wave shaped and provide adequate reinforcement for supporting the weight of grain stored on top. Aprons anchor the duct to the floor, and the duct is connected to a blower which supplies air to the duct. The duct has an inner surface, an outer surface, and two longitudinal edges, with each of the longitudinal edges extending substantially parallel to one another and bear on the respective aprons anchored to the floor. The duct is provided with air outlet openings for injecting air into the grain, wherein the openings are located adjacent or near the longitudinal edges of the duct. Each apron comprises a substantially horizontal wing for anchoring the apron to the floor, thereby forming an air channel between the floor and the inner surface of the duct.

Abstract: The present invention relates to an arrangement for a locking mechanism comprising a lock bolt spring-assisted in the intended direction of locking, which is contained inside a lock casing connected to a plate capable of attachment along the side of a door. An actuating arm projects laterally form said lock bolt and capable of actuation by means of a handle connection extending through a door of the intended kind and a handle projecting on either side of the door. A pivoting follower acts between said handle and actuating arm for the purpose of actuating the actuating arm and the lock bolt. The arrangement has a lock component capable of being caused to move in a linear direction arranged in such a way as to be capable of displacement by means of a pivotally mounted lock component carrier.
Abstract: A peg board panel for supporting a bracket or other generally available hanging element. The panel is comprised of a fabricated metal panel having a front surface, a side surface, a rear surface, and an array of holes extending through the panel. The holes are first punched and then extrusion formed to create an upstanding annular flange extending away from the rear surface of the panel by a predetermined distance or extent. A bracket having a hook is supported by the panel by extending the hook through the hole. The annular flange strengthens the panel and provides a rigid support for the bracket. The hook also has an extent which is equivalent to the predetermined extent of the flange so that no play exists between the bracket and the panel, eliminating brackets that sag or pull out of the panel. The panel diametrical hole sizes and spacing can be varied along the panel.
