The invention relates to a method and a device for checking the seat of a tubeless tire (3) fitted to a rim (2) of a vehicle wheel (1), the vehicle wheel (1) is fastened with its rim (2) centrically on a rotary mount and is rotated about its axis of rotation through at least one revolution. During rotation of the wheel, the outer contours of the radially outer edge areas of the rim (2) and the adjoining areas of the tire (3) are scanned by means of a distance measuring device, and the axial distance differences between the rim (2) and the tire (3) are detected and evaluated.

The present invention provides a method for manufacturing a dental model, which processes the dental model (3) having a model base (2) on which a teeth cast (1) of upper and lower jaws is disposed so as to promote productivity improvement through a reduction in processing time and enable an increase in precision due to the removal of errors when the upper and lower jaws occlude, in the processing and manufacturing of a dental model to be used for a dental treatment, the method comprising: a scan step (100) for acquiring data information by scanning dental information of a patient; an image model generation step (200) for implementing a dental model to be implemented as an image model by graphic-designing an image on the basis of data set on the basis of the dental information acquired through the scan step (100); and a computer aided manufacturing (CAM) processing step (300) for generating the dental model by processing through CAM on the basis of the image model generated through the image model generation step (200), wherein the image model and the dental model (3) acquired through the image model generation step (200) and the CAM processing step (300) are designed and mold-processed such that the teeth model (1) and the model base (2) are integrally formed.

The invention relates to an interlocking device of a draw-out circuit breaker, and belongs to the field of electrical techniques. The draw-out circuit breaker comprises a circuit breaker body and a socket. The circuit breaker body comprises an operating mechanism with a trip lever and a transmission rod. The interlocking device comprises a base, a rotating pushrod, a rotating pushrod actuating device and a rotating pushrod return spring, wherein the rotating pushrod is arranged on the base, and one end of the rotating pushrod which faces to the operating mechanism stretches out of the base, extends into the circuit breaker body and corresponds to the transmission rod; and the rotating pushrod actuating device is assembled on the base, one side of the rotating pushrod actuating device corresponding to the rotating pushrod is in contact with the rotating pushrod, and the part of the rotating pushrod actuating device which faces to the socket stretches out of the base and corresponds to the socket; and one end of the rotating pushrod return spring is born on the rotating pushrod and the other end of the rotating pushrod return spring is born on the base. The interlocking device of the draw-out circuit breaker has the advantages that the assembling errors caused by separate installation are eliminated and the action reliability is ensured; the invasion of dust and foreign matters is avoided; the interlocking device is universally suitable for draw-out circuit breakers at different current ratings; and since the overall structure is simple, the manufacturing, installation and maintenance are facilitated.

The invention relates to the technical field of reactor auxiliary equipment, and discloses a flow blocker for a high temperature gas cooled reactor. The flow blocker comprises a casing and a rotor component. A cavity is formed in the casing, and a feed inlet and a discharge outlet both communicated with the cavity are arranged on the casing. The rotor component comprises a rotating shaft and a rotating disc. The rotating shaft is rotatably mounted in the cavity around the axis. The rotating disc is coaxially arranged on the rotating shaft. The outer peripheral surface of the rotating disc is in clearance fit with the curved surface of the cavity. The outer peripheral surface of the rotating disc is provided with a plurality of positioning grooves and at least one receiving cup for accommodating materials. The receiving cups are located between every two adjacent positioning grooves. An elastic block is embedded in each positioning groove. The outer surface of each elastic block is abutted against the curved surface of the cavity to stop gas circulation between the feed inlet and the discharge outlet. The flow blocker has the advantages that the elastic blocks are provided to achieve buffering through the elastic force, normal circulation, loading and unloading of spherical elements can be maintained, the stability in long-term operation is high, and high-temperature thermal expansion compensation and mechanical wear compensation can be realized.

The invention provides a combined adjusting and jointing method and a combined adjusting and jointing mechanism for a visible light imaging system and an imaging focal plane. The problem that the accuracy of perpendicularity between an optical axis of an optical imaging system and the imaging focal plane, the accuracy of an overlap ratio between the optical axis of the optical imaging system and the central normal of the target surface of the imaging focal plane and the accuracy of an overlap ratio between the image plane of the optical imaging system and the imaging focal plane in the conventional image plane jointing process cannot be ensured is mainly solved. By once clamping of a high-accuracy double-shaft lathe, a set regulation aim is fulfilled, the set regulation accuracy is achieved, and meanwhile, the jointing reference surface of a focal plane component and the end face of an optical lens mounting flange are turned, so that the parallelism between two planes is ensured, and an assembly error, which is caused by a previous assembly link, of the focal plane component and an optical lens is completely eliminated.
