Abstract: A moving apparatus for a pneumatically supported membrane structure is described herein, which apparatus has a rigid movable frame disposed along a lower peripheral edge of a pneumatically supported membrane structure, the rigid movable frame being constructed in such manner that upon moving the pneumatically supported membrane structure, the structure can be moved while maintaining its shape under the condition that said frame is separated upwardly from a floor surface on which the structure is moved.

Abstract: A structure employing a tapered slab, which is formed of a two-dimensional continuous array of upside-down rectangular pyramids with their apexes placed at column centers and their bottom faces placed along an upper surface of a floor slab, is improved in that prestressing steel members are disposed under tension between the top portions of the respective columns and said prestressing steel members are anchored to the columns at the outer ends.

Abstract: A precast concrete silo complex and a method of constructing it, in which quarter-cylindrical precast concrete members, constituting unit members, are each provided with a pair of radially protruding couplings near both the ends of the member, and the unit members are arranged to form unit cylinders. The unit cylinders are arranged lengthwise and crosswise, with the couplings facing the couplings of adjacent unit cylinders for defining a coupling space between each two adjacent unit cylinders. Horizontal clamp rods extend through the coupling spaces between the end portions of the unit members and between the couplings, and concrete is provided in the coupling spaces. The horizontal clamp rods are tensioned to clamp the end portions of the unit members and the couplings, to give prestress to the concrete, thereby combining the adjacent unit cylinders and solidifying the unit cylinders arranged lengthwise and crosswise.

Abstract: A method for making a decorative plate used in a building characterized by making a transfer sheet by applying a primer layer comprising a water-soluble binder to the surface of a synthetic resin sheet, printing a pattern comprising a coloring agent and a binder, at least one of which is water-soluble, on the primer layer, making a mold for a slip casting having the pattern layer on the inside surface by shaping the transfer sheet with the surface of the pattern layer upward, pouring a mixture comprising a hydraulic material and water into the mold, hardening the mixture, and stripping the synthetic resin sheet from the resulting decorative plate produced.

Abstract: A pneumatic apparatus used for reading punch cards containing processing condition data for articles being processed in an automatic system. The apparatus has a pneumatic reading head for reading the punch cards, and the head has a plurality of air conduits therein. Each conduit has an inlet and an outlet. An air supply is connected to the air conduits for supplying air thereto, and a back pressure detector is provided in each conduit for detecting back pressure therein. The apparatus also includes a movable carrier jig for holding and carrying the article being processed in said system and the jig has a card fitting portion thereon for holding the punch card. The carrier jig is movable toward and away from the conduits so that the card on the card fitting portion can be positioned adjacent the outlets of the conduits.

Abstract: When plating an outer surface of a cylindrical article or an inner surface of a tubular article, in order to automatically achieve centering between the article to be plated and the opposed tubular or cylindrical electrode, there is provided a novel jig for supporting the cylindrical body, either the article to be plated or the opposed electrode, at the center of the tubular body, either the opposed electrode or the article to be plated, and a method for automatically centering the cylindrical body and the tubular body by means of said jig. The jig consists of a jig receiving member having a jig supporting surface in the form of an inclined surface or a spherical surface having a center axis, and a jig member having a surface by which the jig member is to be supported which is mated with the jig supporting surface and which is coaxial with the center axis of the jig supporting member, and the pair of mating surfaces serve as electric conduction means between the cylindrical body and an external circuit.

Abstract: Method of treating a sticky material-containing exhaust gas to remove the sticky material therefrom, by introducing pulverized coal or coke having a particle size of 0.3mm or less into the bottom of a hopper, which is positioned below, and integrally connected with, a bag-house containing bag-filters, to form a protective layer of pulverized coal or coke having a thickness of at least 1mm on the surface of each bag-filter, and then introducing the sticky material-containing exhaust gas into said hopper in a manner such that the gas passes through said protective layer while said protective layer captures and retains the sticky material.

Abstract: An improved article conveying apparatus suitable for conveying an article to be processed from an article receiving station to a processing station and for conveying a processed article from the processing station to a product delivery station in a highly efficient manner. This article conveying apparatus has an apparatus main body supported on a track and capable of travelling along said track, an arm supporting frame mounted on the apparatus main body so as to be rotatable about a vertical axis, at least a pair of arms mounted on the frame in a vertically movable manner, and article supporting devices mounted on the respective arms at an equal distance from the vertical axis.

Abstract: A process for indirectly detecting a misfired explosive (cartridge) which comprises charging a ferrite magnet as a tracer in an explosive charging portion together with an explosive in a blasting method and detecting the magnetic flux of said magnet charged in a misfired explosive cartridge at a site of explosion after blasting by a magnet measuring instrument, characterized by using as said tracer a ferrite magnet calcined at a temperature less than 1000.degree. C. and detecting this magnet by said magnetic detector.

Abstract: A large lightweight gypsum article comprising anhydrous or hemihydrous gypsum, ettringite, reinforcing members, and, if necessary, fibers and/or light-weight aggregate.

Abstract: Equipment for treating waste gas containing tar mist is constituted by bag houses having bag filters therein and in which a filter cleaning apparatus for each filter is installed, respectively, a conducting duct for waste gas containing tar mist connected to each bag house and equipped with a shut-off valve, respectively, a discharging duct for treated waste gas and a supply tube for supplying protective coating material which is caused to form a precoated layer on the surface of the bag filter. The efficiency of the waste gas treatment is improved by the action of the precoated layer in inhibiting the direct contact of tar mist with the bag filter.
