摘要： A method and apparatus for casting concrete products by means of continuous slide casting so that concrete is extruded onto a bed (4), into a space between the bed and a mold, by means of a feeding member or members of a slide casting device travelling along the bed, the mass is compacted, and recesses are pressed onto the surface of the product by means of a roller and/or an endless belt (12) provided with protrusions. The recesses are at least partly discontinuous in the direction of the casting, and they are pressed into the upper surface of the slab at the latest during the compacting implemented following the feeding member or members, before the mix has been fully compacted.

摘要： A method for determining the performance of a control valve in a closed control loop by using a simulation model. A simulation model of a process control loop is provided, consisting of a unit process (2) including the flow equations of the valve, a process controller (4) and a process transmitter (3), to simulate a process with disturbances (6, 6'). The simulation model is connected to a real control valve (1), including a valve, an actuator and a positioner. The valve response is measured. The process variability during the process is determined.

摘要： A concrete joint slab structure comprising a first part (1) cast in advance, one surface thereof being provided with several parallel ridges (2), and a second part cast on top of said first part, extending into the grooves between the ridges of the first part. The ridges (2) are provided with a portion that is narrower than the outer portion thereof. The slab can be used also in a noise barrier consisting of a compact load-bearing concrete layer and a more porous noise absorbing concrete layer.

摘要： A method and equipment for controlling a pipe network comprising piping (1), a pump (2) and at least two control valves (3), whereby the valve position and the flow through the valve are monitored, and in order to achieve desired flows the rotational speed of the pump and the position of each valve are adjusted on the basis to the position and flow data received. The rotational speed of the pump (2) is adjusted to be as low as possible, but at the same time sufficient for maintaining the gain of the valves (3). The positions of the valves (3) are adjusted to be as open as possible, the valve opening being, however, for the major part of the time, not more than a certain predetermined portion of the opening of the totally open position.

摘要： A hydraulic control system for a gyratory crusher with a hydraulically supported main shaft. The inlet line (3) of hydraulic fluid is provided with a pressure relief valve (5), such that when the pressure in the cylinder, e.g. because of a disturbance, exceeds the opening pressure of the relief valve, fluid flows from the cylinder through the pressure relief valve to the lubricating circuit of the crusher. The safety system thus constructed is simple, reliable, and quick.

摘要： A method for mounting a wear plate and a knife base on a disc chipper's disc, and a disc chipper. The wear plate (6) rests against the knife base (4) via two counter surfaces (12), one of which forms in the wear plate (6) a groove in parallel to the knife (3) and the other forms in the knife base (4) a ridge which can be fitted into this groove. The tightening force of fastening bolts (17, 18) of the wear plate (6) presses the knife base (4) against the disc (1) by means of the wear plate via these counter surfaces (12).

摘要： A method for producing a concrete, plaster, gypsum or corresponding mix by using water and binder hardening by the action of water and possibly mineral aggregate. The mix is mixed so rapidly in the mixing chamber of a mixing device that an essential early workability of short duration and a subsequent essential early stiffening are created. The mix is caused to move from the point of contact between water and binder to the discharge end of the mixing device and further directly into a casting mould or nozzle or onto a desired surface before the essential early workability of short duration occurring immediately after adding water is reduced and the essential early stiffening begins.
