Patent SE-8405405-D0 (SE)
Inventor: ASK W
IPC: B23D55/00
Filed: 1984-10-29
Abstract: Circular saws (Fig 1), band saws (Fig. 2) or frame saws (Fig. 3) are intended for sawing straight as well as curved timber with knots and other irregularities which tend to direct the saw blade so that the kerf deviates from the desired kerf. It is known to design saw blades as a pack of at least two blades close to each other (1, 2). According to the invention the two saw blades are driven with intentionally variable relative speeds, each of them having their row of teeth (3, 4) which cannot interfere with the other row. Deviations from a wanted kerf are indicated by means of the deflections of the saw blade pack when it goes through the object to be sawn. The deviation controls the relative speeds of the saw blade halves. The saw blade which at a certain moment goes faster cuts a void towards which the pack is forced by the pressure from the teeth of the other saw blade. The method can be used on one hand to guide the saw to produce a straight kerf, on the other hand to guide the saw manually, and further to guide the saw according to a program for example to obtain planks with constant thickness from curved logs and also for joineries. It is also possible to produce chips with long fibres cheaper for fibreboard production.

Abstract: When practicing a method and using an arrangement for producing a fibre layer or fibre mat from a liquid-absorbent material, e.g. in the manufacture of diapers, a fibre-air suspension is blown in between two endless, mutually parallel air-permeable conveyor belts (12,13) at a pressure which exceeds the pressure of the ambient surroundings. The conveyor belts form therebetween a forming space which is defined laterally by stationary or movable side-walls (18), the inner surfaces of which may be profiled so as to provide a fibre layer or a fibre mat with profiled side-edges.

Abstract: Apparatus and method for inspecting a tubular member for degradation, which tubular member may be a control rod drive mechanism (CRDM) penetration tube of the kind typically found in nuclear power reactor pressure vessels. The CRDM penetration tube includes a thermal sleeve concentrically disposed therein, the sleeve being radially rotatable and axially translatable within the tube. However, the sleeve may be nonhomogeneous, which nonhomogeneity could undesirably mask the inspection signal as the inspection sensor is radially and axially moved in order to inspect the tube. The apparatus includes a support body sized to be disposed in the sleeve, an expandable bladder connected to the support body to engage the sleeve for securing the support body to the sleeve, one or more sensors connected to the support body for sensing the degradation in the tube, and a rotator connected to the support body for simultaneously rotating the support body, the bladder, the sensor and the sleeve in the tube to radially scan the tube. A pusher/puller mechanism is also provided, the pusher/pusher mechanism being connected to the support body for simultaneously translating the support body, the bladder, the sensor and the sleeve to axially scan the tube. As the support body is rotated and translated, the sleeve is stationary with respect to the sensor because the bladder secures the sleeve to the support body; thus, as the support body, and the sensor connected thereto are rotated and translated, the sleeve will be rotated and translated to a like extent. In this manner the material properties of the sleeve are radially and axially invariant relative to the sensor, for obtaining a more precise inspection of the tube.
