Patent EP-0474266-A2 (EP)
Inventor: LEHNHARDT FRITZ-JOACHIM DR
IPC: A61M37/00

Abstract: A small experimental animal is characterised by an implanted catheter device for experimental microsurgery. This device consists of a housing in the form of a tubular, straight sleeve (10) which has at one end area a cavity (13) which is closed at the end face of the sleeve (10) by an upper wall (14) which can be pierced by a needle. The other end area of the sleeve (10) forms a connection part (30) in which a clamping space (21) is designed for receiving an elastomeric clamping piece (11) which surrounds a catheter (12). The piece of the connection part (30) projecting beyond the clamping piece (11) is equipped with an internal thread (31) into which an externally threaded shaft (32) of a pressure piece (20) can be screwed. The end face of the externally threaded shaft (32) of the pressure piece (20) presses axially against the clamping piece (11) in order to press it sealingly by means of radial deformation against the catheter (12), which in this area sits on a rigid supporting cannula (22) whose lumen communicates with the cavity (13) and which projects into the pressure piece (20). The catheter device is of very small dimensions and is implanted in the smallest possible experimental animal. Infections, thromboses or catheter expulsions do not occur in practice, and the experimental animal permits long-term, experimental studies without the animal being immobilised. <IMAGE>

Abstract: A wideband, frequency synthesized, fault-tolerant microwave signal generator (50) is described which can generate the spectrally pure transmitter or antenna drive and receiver first local oscillator (LO) signals needed for advanced tactiacl airborne radar systems. Separate generation of the transmitter drive (TD) and first LO minimizes spurious signal generation over a wide operating band, typically 45% or greater. Extensive fault tolerance is provided without resort to redundant hardware. The sharing of two internal signal generators (60, 70) limits the frequency generation needs to just the operating band for economy of required hardware.

Abstract: Disclosed is an in-furance slag level measuring apparatus having a microwave radar (52) for measuring a slag level in a convertor (41) or the like. The level of a transmission signal or a reception signal is adjusted in accordance with the level of a detection signal so that the signal level in the microwave radar is adjusted to be constant. Further, the level measurement value and the detection signal are inputted and the level measurement values obtained in a predetermined time are subjected to averaging operation. In the averaging operation, when the detection signal is smaller than a set point, the averaging operation is performed while disregarding the level measurement value at that time.

Abstract: Battery plates from the high speed output conveyor (12) of a pasted plate making machine are deposited onto a lower speed first conveyor (10) in an overlapped fashion to create a shingled stream of plates (18). As plates drop off of the discharge end (19) of the first conveyor (10) they are accumulated in vertical stacks (31) on a second conveyor (24) that is located below the first conveyor (10). Whenever a stack (31) is completed the second conveyor (24) is moved approximately one plate width to remove the stack and the process continues. In order to provide time to move the stack, the flow of plates (18) on the first conveyor (10) is disrupted when the stack (31) is being moved. In the preferred embodiment the disruption is caused by squeezing the plates between the jaws (38, 42) of a clamping mechanism (36) that the plates pass through. A counter (20) is used to count the number of plates in a stack and a controller (22) causes the clamping mechanism (36) to be engaged at the proper time, causes the second conveyor (24) to remove the just-formed stack and then causes the second conveyor (24) to stop and the clamping mechanism to be reopened so that a second stack can be formed. A gate (32) extends across the second conveyor (24) when the stack is being formed to ensure that the stack is straight. The gate (32) is raised upon command from the controller (22) when movement of the second conveyor (24) commences and is lowered again when movement of the second conveyor ceases.

Abstract: A method is disclosed for the conditional deletion of selected data objects within a data processing system. In a data processing system having a plurality of data objects stored within a library service, it is common for a selected data object to be utilized or temporarily removed by a system user. In response to a request to delete a selected data object, a determination is first made whether the data object in question is in use or temporarily removed from the library service. If the data object to be deleted is in use or temporarily removed, the deletion of that data object is automatically halted in accordance with the method of the present invention. In one embodiment of the present invention, the deletion of a selected data object may be temporarily deferred in response to a determination that the data object is in use or temporarily removed, until such time as the data object is returned to the library service or no longer in use. In each disclosed embodiment of the present invention, the authority to delete a particular data object is determined prior to permitting such deletion.

Abstract: A convergence control system for multiple vertical modes or formats, having respective rasters with different vertical heights, comprises a selector (4) for initiating operation in one of the available vertical modes, and a circuit (40) for generating convergence correction signals responsive to the selector. The correction signals are generated from known convergence correction values and by interpolation of the known values. The convergence correction values may be stored and sequentially processed by digital circuits and the interpolation may be undertaken by analog circuits. The circuit for generating convergence correction signals may comprise a digital data store (46) for different sets of convergence correction values, for generating selectable sets of correction signals for different vertical modes or formats, for example normal and overscanned modes. The sets of convergence correction values define different sets of grid lines and rows of horizontal scan lines. Adjacent ones of the grid lines are spaced from one another at different intervals for different vertical formats. The intervals between adjacent horizontal grid lines are greater for vertical formats having rasters with greater vertical heights. An interpolating circuit (40) for processing the known convergence correction values is responsive to the horizontal deflection circuit. The interpolating intervals can be adjusted to correspond to the horizontal scanning rate. The number of interpolating intervals is matched to the number of horizontal scan lines in each row.
