A composite for constructing concrete floors is completely factory assembled and comprises a body of expanded plastic having at least two parallel channels, open on the upper surface of the panel, extending the length of the article, adapted to be filled with concrete. A steel reinforcement bar fabric is installed into each channel, which may comprise at least two parallel steel bars connected by cross bars. At least some cross bars extend beyond a lowest reinforcement fabric bar to provide spikes long enough to pass through the plastic bottom and protrude therefrom. One or more sheet metal shrouds with at least one row of aligned holes matching those of the protruding spike ends are applied to the underside surface of the plastic body hung from the protruding ends of the spike by fasteners

A method of inspecting the profile of the connection zone between the cylindrical portion and the taper of a turbomachine part, the surface profile of the part being geometrically defined by at least one first zone corresponding to the taper of the part, at least one second zone corresponding to the connection between the cylindrical portion and the taper of the part, and a third zone corresponding to the cylindrical portion of the part, the method consisting in measuring the surface profile of the part; from the measured surface profile, modeling the contact pressures that apply to the surface of the part for each of its zones; and comparing the contact pressures modeled for the second zone of the surface profile of the part with predefined threshold values.

The method and system for detection of anomalous work pieces during a production process, comprising computing for each production process step of the production process at least one deviation data signal for a target data signal of a target work piece with respect to reference data signals recorded for a corresponding production process step of a set of reference work pieces, wherein the deviation data signal comprises a number of deviation data samples for different production time steps, t, or path length steps, 1, of the respective production process step; performing a stepwise anomaly detection by data processing of the at least one computed deviation data signal and a process type indicator indicating a type of the production process step using a trained anomaly detection data modelto calculate for each time step, t, or path length step, 1, of the production process step an anomaly probability, p, that the respective time step, t, or path length step, 1, is anomalous; and classifying (S3) the target work piece and / or the production process step as being anomalous or not anomalous on the basis of the calculated anomaly probabilities, p, of the time steps, t, or path length steps, 1, of the production process step, wherein if the target work piece and / or the production process step is classified as anomalous, a warning signal for a user and / or a control signal for a production machine can be generated automatically.

A method of inspecting the profile of the connection zone between the cylindrical portion and the taper of a roller for a turbomachine roller bearing. The method includes taking a measurement of the surface profile of the roller; on the basis of a calculation of the first derivative of the measured profile, calculating straight line segments for each of the geometrical zones of the roller, where the straight line segments model the first derivative of the measured profile; calculating the radii of curvature of the surface profile of the roller by taking the first derivative of the straight line segments; and comparing the calculated radii of curvature with predefined threshold values in order to verify continuity thereof.

The invention especially relates to a production process for a double-dot coating composite sponge used for an automobile fabric and an automobile composite fabric, belonging to the technical field of fabrics. The production process overcomes the problems of proneness to generation of pits, environment unfriendliness and the like in the prior art. The production process for the double-dot coating composite sponge comprises the following steps: A, gluing; and B, compounding. The automobile composite fabric is prepared by using the production process. The invention has the advantages that manufacturing cost is reduced; pits are prevented; peeling strength is improved; and environmental protection is better realized.

The invention relates to the technical field of shoemaking machinery, in particular to a toe lasting machine. The toe lasting machine comprises a left claw chuck, a right claw chuck and a front claw chuck which are movably arranged on a large plate of the machine; the left claw chuck is provided with a first mounting surface and a first moving guide slot, which face upwards; the first moving guide slot is arranged to be matched with a first limiting part on the large plate; a plurality of left claws are arranged on the first mounting surface; the right claw chuck is symmetrical to the left claw chuck and is provided with a second mounting surface and a second moving guide slot, which face upwards; the second moving guide slot is arranged to be matched with a second limiting part on the large plate; a plurality of right claws are arranged on the second mounting surface; front claws are arranged on the front claw chuck, and the front claws, the left claws and the right claws are arranged and distributed on the periphery of a shoe last holding station respectively; and a power cylinder synchronously drives the left claw chuck and the right claw chuck through a push rod, while the left claw chuck and the right claw chuck are combined to drive the front claw chuck. Due to cooperative inner displacement of the left claw chuck, the right claw chuck and the front claw chuck, the vamp edge is completely attached to the shoe last, and the lasted vamp is smooth and flat and has no wrinkle or hollowing.

The invention relates to a wagon arc side wall assembly production process. The wagon arc side wall assembly comprises a first side wall plate, a second side wall plate and a third side wall plate which are cambered and welded successively from the top to the bottom. An upper side beam assembly is welded and fixed on a top end plate wall of the first side wall plate. A side wall stiffening beam assembly is welded and fixed longitudinally at the first side wall plate and second side wall plate side wall welding position. A lower side beam assembly is welded and fixed longitudinally at the second side wall plate and third side wall plate welding position. A lower side beam reinforcing beam assembly is welded and fixed longitudinally below the lower side beam assembly. According to the production process, by the side wall plate longitudinal splicing design mode and different-thickness design, spliced welded joints are hidden, the spliced welded joint length is reduced effectively, the joint groove machining amount and the welding material consumption are reduced, the production efficiency is improved, and costs are saved; the side wall flatness is controlled effectively, and the appearance is attractive; the process is simplified, the production difficulty and the labor intensity are reduced, the tooling equipment investment is simple, and the efficiency is improved effectively.
