摘要:
The invention relates to a machining device for machining a workpiece (W), wherein a rotatably mounted machining tool (2a) is held in a machining unit (2), and the machining unit (2) can be moved axially along the axis of rotation (X) of the machining tool (2a) by means of a feed device (10). The machining device comprises a pressure plate (6), mounted in a freely movable manner by means of a bearing device (4), and a measuring device (8) for position detection. According to the invention, the pressure plate (6) and the bearing device (4) constitute part of a pressure-exerting unit (12), and the pressure-exerting unit (12) can be moved axially with respect to the machining unit (2) in the direction of the axis of rotation (X) and independently of the machining unit (2) by means of a drive device (14) assigned to said pressure-exerting unit.

The invention relates to a machining device for machining a workpiece, wherein a rotatably mounted machining tool (2a) is held in a machining unit (2), and the axis of rotation (X) of the machining tool (2a) can be aligned with the workpiece surface to be machined, and therefore the axis of rotation (X) coincides with the geometric normal (N) in the machining point of the workpiece surface. The machining device comprises a pressure plate (6) mounted in a freely rotatable manner on the machining device via a bearing device (4), and a measuring device (8) for detecting a deviation in the position of the pressure plate (6). According to the invention, the bearing device (4) has a bearing body (40b) having at least one spherical surface region, and a bearing receptacle (40a) which surrounds the bearing body (40b) at the spherical surface regions in a form-fitting manner.
摘要:
A show cabinet for displaying objects, one of the side panels of which is in the form of a glass door, the outer face of which, in the area of the outer edge when in the closed position, closes flush with one side panel of the cabinet in order to seal off the interior of the cabinet in a dust-tight and airtight manner against its surroundings, appropriate flexible sealing strips being affixed in the area of movement of the door. The door is mounted by a guiding means in such a way that it can be moved sideways in a parallel manner until the door opening is completely clear; to open the door, the relevant side panel (5) can be pushed back, or the door can be moved forward, to such an extent that the inner face (8) of the door (3) is able to pass the front edge (7) of the side panel (5)
摘要:
A device and method are disclosed for selective exposure of a biological sample, preferably biological cell material, to sound waves. The device is provided with a receptacle for the sample, in which the biological sample is in a suspended form, and having an electroacoustic transducer device, which generates sound waves and which is disposed outside the receptacle of the sample in such a manner that sound-wave coupling into said sample occurs through the wall of said receptacle.

A display case having a preferably square or rectangular outline and a front (1), a rear (2), an upper (5), a right (3) and a left side face (4), a base (6) or in addition an upper part (14) instead of the upper side face (5), all the side faces or at least a part of the same being formed of panes of glass, the interior being sealed in its lower region with a support surface (7) and the display case being sealed extensively in an airtight manner relative to the external air. The display case being formed from two symmetrical halves (8, 9) which are separated from each other vertically, the base (6) and the possibly present upper part (14) forming a part of the front (1), rear (2), right (3) and left side face (4) and the two halves (8, 9) being able to be moved away from each other or towards each other horizontally and parallel, the support surface (7) being excluded from the movement. Such a display case has no door, access to the interior is nevertheless provided in the open state.

A glass cabinet for storage and/or display of objects includes a front, a rear (2), a right (3) and a left lateral surface (4), a bottom piece (5) and an upper piece (6) forming the top, at least one lateral surface, for example, the front lateral surface being formed as a glass door (1), in the closed state of the glass cabinet, the interior thereof being sealed in an airtight manner to the environment and the door (1) being mounted displaceably laterally parallel by a guide means mounted in the region of the upper piece or the lower piece or respectively in the region of the upper and the lower piece until release of half of the door opening. In this position, the guide means is formed in such a manner that the projecting part of the door (1) can be pivoted in this position so far that this part of the door (1) adjoins the left (3) or right lateral surface (4). Such a design of a glass cabinet is particularly suitable for those with a very large width.

A cabinet for displaying objects comprises a top part (1) resting on an under part and which consists of a top face, a rear side (3), left (4) and right (6) sides, a bottom face (10) and a front side (5) consisting of a glass sheet (25) pivotally fitted on the top face (9) to swing upwardly. The glass sheet (25) is surrounded by a frame (11) on all sides. In the region of the front side (5) a gas spring (13) is rotatably attached to the bottom face (10) in the region of each of the left (4) and right (6) sides and acts in the region of the middle of the frame (11). The pivoting movement of the front side (5) is effected by screw jacks (14) acting above each of the gas springs (13) and driven by electric motors. Synchronous operation of the two electric motors is ensured by an electronic control device.
摘要:
Techniques for automatically maintaining continuity in animation across discrete animation changes. Smooth animation is achieved without forcing the animator to manually calculate compensation values or introducing extra controls to the models that are animated. Continuity or smoothness of the animation is maintained as varying aspects of the animation change under continued authoring.
摘要:
A shelve cabinet comprises partially cooled shelves which are open towards the front and wherein the goods compartment is cooled by a cool-air curtain flowing through the at least partially perforated rear wall of the goods compartment into the goods compartment and/or by a cool-air curtain flowing along the goods compartment opening. One or more goods display shelves are located in the goods compartment, the goods display shelves being configured in such a manner that the at last one partial flow of the cool-air curtain is guided across them to the front area of the goods display shelves. The goods display shelves are provided with structure for stabilizing at least one partial flow of the cool-air curtain flowing along the goods compartment opening. The goods display shelves are linked with the rear wall of the goods compartment in an air-tight manner and the structure for stabilizing the cool-air curtain flowing along the goods compartment opening are adapted to deviate the cool-air curtain in the direction of the goods compartment.
摘要:
A cabinet has a top part (1) consisting of glass sheets and an under part (8), wherein the top part (1) is composed of a top face (2) and a plurality of sides (3, 4, 5 and 6). A screw jack (10) driven by an electric motor (11) is fitted in each corner in the under part (8) to raise the top part (1). Synchronous running of all the electric motors (11) during the raising or lowering operation of the top part (1) is ensured by a common electronic control device (12) which is fitted in the under part (8).
