Patent EP-0404547-A2 (EP)
Inventor: JASCHEK REINHARD ALBERT REINHO
IPC: F16C17/14
Filed: 1990-06-20
Abstract: A bearing for a submerged machine comprises first and second bearing elements. A first bearing element (16) is formed as an insert which fits into a shaft (12) of a turbine (10) of the machine. The second bearing element is an insert (22) which is retained within the housing of the machine. The insert (16) defines a conical recess (18), while the insert (22) defines a complemental conical projection (24). The inserts are made of plastics materials with mutually self lubricating properties. In use, centrifugal forces expel abrasive particles from the interface between the bearing surfaces of the respective inserts, increasing the service life of the bearing.

Abstract: A method of reducing image helical scanning artifacts in computed tomography imaging systems divides 360° of projection data into two half scans. Separate weighting functions are applied to the two half scans and they are reconstructed to an image per conventional reconstruction methods. The weighting functions provide effective interpolation and extrapolation of the half scan data to a slice plane centered in the projection data. In one embodiment, the weighting functions are feathered with a cubic function to remove weighting induced image artifacts. Apparatus for carrying out the method is also disclosed.

Abstract: The electrical snap-action switch, particularly a microswitch, is provided with a rocker arm (18) which supports contacts, can pivot, rests with its one end against a retaining bearing (17) and, on its other end, engages on a switching spring (19) which pulls the rocker arm against the retaining bearing. In this case, the switch has an operating element (15) which moves parts of the switching spring in order to transfer the rocker arm into its individual switching positions. In order that the operating element can carry out a relatively large movement (excess movement) than is necessary for the actual changeover switching, the operating element, which can move essentially at right angles to the switching spring longitudinal axis, has in its longitudinal direction a recess (23) which in places forms a frame around the switching spring and is bounded essentially by a stop (25, 26) which touches the switching spring in one switching position, in this case the recess is designed to be long in such a manner that the switching spring which is located in the recess is free from the stop in a relatively large movement range of the operating element. <IMAGE>

Abstract: Device for generating a current (I) corresponding to the input quantity (A) of the device, for example for a digitally working process control system, comprises two parallel-working current-generating members (1, 2), each one connected to a current summation member (3). The current-generating members are each one adapted to generate a current (I1, I2) proportional to the quantity (A), the proportionality being determined by an influenceable proportionality factor (k1, k2). Further, each one of the current-generating members is adapted to supervise both its own function and that of the other member. Upon indication of a malfunction in one of the current-generating members, the function of the device is taken over by the other member alone. Each one of the current-generating members may preferably by adapted, by means of switching members (6, 7), to establish an alternative path for the generated current. The device is further adapted to sense whether an indicated malfunction in one of the current-generating members is caused by an internal fault in the current-generating member or by an external fault such as an interruption in the part of the circuit, which is connected to the current measuring member.

Filed: 1991-05-28
Abstract: An FDDI system and method for transmitting to an optical medium, upon receipt of token, frames of synchronous data and frames of asynchronous data having different levels of priority. The network on which the FDDI is implemented includes a plurality of processors each having a system memory for storing the frames of data in queues corresponding to priority, and an output buffer configured to have a plurality of logical FIFOs corresponding to the queues. Data is transferred one queue at a time from the system memory to the output buffer through a single physical FIFO. To prevent the FIFO from "locking-up" as a result of any residual data remaining therein following each transfer of a frame to the output buffer, storage remaining available for a particular queue of the output buffer to be transmitted to the medium is detected. Data is transferred from the system memory to the FIFO memory only if the storage remaining available is at least equal to the storage capacity of the FIFO memory.

Abstract: Microminiature pressure transducers are formed on semiconductor substrates such as silicon and include a membrane (25) which spans a cavity (35) over the substrate (21), with the membrane being mounted to and sealed to the substrate at the peripheral edges of the membrane. The bottom (36) of the cavity forms an overpressure stop to prevent over deflections of the membrane toward the substrate. An overpressure stop (27) formed as a bridge of a material such as nickel extends above the membrane and is spaced therefrom to allow the membrane to deflect freely under normal pressure situations but prevent over deflections. The thickness of the polysilicon membrane and the spacing between the membrane and the overpressure stops is preferably in the range of 10 micrometers or less, and typically in the range of one micrometer. The overpressure stop bridge is formed utilizing deep X-ray lithography to form a well-defined bridge structure. The gap between the membrane and the bottom surface (32) of the bridge is established with a sacrificial layer, such as a polyimide film, which dissolves in a solvent. The transducer is formed utilizing processing techniques which do not affect the performance of the membrane as a pressure sensor and which allow the substrate to have further micromechanical or microelectronic devices formed thereon.

Abstract: The clamping device is intended for single tools and has a tension part (7) which is accommodated in a spindle (4) and with which a tool holder (8) or a tool (26) can be restrained on the spindle (4), relative to which the tool holder (8) or the tool (26) can be centred. The tension part (7) has a conical clamping and centring part (18) which lies in the area outside the spindle (4) and interacts with at least one conical surface (39, 40). The latter is provided on the tool (26) or the tool holder (8) and lies in an end recess (30) of the tool (26) or the tool holder (8). With the clamping and centring part (18), the tool holder (8) or the tool (26) is centred and clamped in one step with regard to the spindle (4). Since the clamping and centring part (18) lies outside the spindle (4) and the conical surfaces (39, 40) are provided in the end recess (30), the tool (26) or the tool holder (8) does not need to be inserted into the spindle (4). The changing operation can consequently be carried out within a very short time.
