Abstract: Diese Schaltungsanordnung weist ein Interpolationsfilter (3) auf, in dem die ankommenden Signalwerte (A) in interpolierte Signalwerte (B) mit erhöhter Folgefrequenz (Üxfs) umgesetzt werden. Die Signalwerte (B) werden mittels Quantisierer (4a), Quantisierungsfehlerrückführung und Fehlerfilter (25) in der Wortlänge reduziert. Ein D/A-Wandler (6) besteht aus mehreren parallellliegenden, nichtgewichteten Schaltstufen. Die jeweils aktivierten Schaltstufen geben Teilströme ab, die ausgangsseitig addiert werden. Der D/A-Wandler (6) wird von einer Ansteuerschaltung (5) gesteuert, die die Ausgangsignale (D) des Interpolationsfilters (3) verarbeitet. Die aktivierten Schaltstufen werden laufend zyklisch vertauscht, so daß sich relative Widerstandstoleranzen in der Schaltungsanordnung im Mittel ausgleichen.

Abstract: A data processor includes a bus interface coupled to an external bus for transferring information to and from the external bus, an instruction decoding section coupled to the bus interface to receiving an instruction through the bus interface from the external bus so as to decode the received instruction, and an instruction execution unit coupled to receive a decoded information from the decoder so as to execute the received decoded information. The decoding section includes an instruction decoder receiving an instruction through the bus interface to output the decoded information to the execution unit and to generate a tag information, an effective address generator receiving the tag information to calculate an effective address, and a memory management unit receiving the effective address to generate a real address. When the tag information indicates that the decoded information is a predetermined input/output instruction, the memory management controls the bus interface to limit a data transfer between the external bus and the bus interface until a predetermined condition is satisfied.

Abstract: Plastic compositions having good sonar trans­mission, that is low loss of sound transmission, are a composite of a low loss sonar material, for example polyethylene, and a high tensile strength material, for example fiberglass, adhered together by a binder, for example an epoxy. The composite generally has a tensile strength of greater than 100,000 PSI. The composites unexpectantly have a lower sound level loss than would be expected based upon a linear proportion of the amount of high flexural strength material contained therein.

Abstract: In this arrangement according to Figure 1 for copying a workpiece (W), data on the workpiece (W) are acquired by scanning a model (M), digitised and stored. The data acquired in this way are converted into NC sets and a relative tool correction is carried out for the drives of the NC machine in order to determine the control signals, during which correction the generally different dimensions of scanning sphere (T) during the scanning of the model (M) and of the radius of the cutter (F) when producing the workpiece (W) are taken into account. A correction movement ( DELTA  Z) is superimposed on the relative movement between cutter (F) and workpiece (W) if contour elevations are determined during collision considerations inside the projection surface (FP) of the cutter (F).

Abstract: The device has a rectangular housing (2) defining between opposite pairs of upstanding walls (3,4) (see Fig. 1) a ventilation opening controlled by overlapping flaps (5) pivotally movable about hinge axes (61) by means of a drive device (not shown). The flaps (5) have end walls (271) which extend downwardly outside the housing walls (4) and in the regions of their overlap the flaps are formed with water collecting channels (221). The flap outer walls (171) first rise steeply in an initial portion (231) adjacent the bottom of the channels (221) and then incline more gently upwards to end beyond a culmination line (251) in an end portion (261) inclined slightly down­wards. To assist in preventing spillage of surface water through the ventilation opening when opening the flaps (5) an upright water deflector lip (321) is provided midway of the initial portion (231) of each flap outer surface which lip projects with its ends (331) beyond the end walls (271) of the flap. The outside of the end walls (271) of the flaps also have further water deflector ribs (371) which extend obliquely downwards past the discharge mouths of the water collecting channels (221).

     Clamping means (13) coupled to the first rotary member (31) are movable, with a motion that includes an angular component and an axial component, between a clamping position in which the clamping means (13) clamps a load axially against the supporting surface (2) and a retracted position allowing loading and unloading of the load. 
     The arrangement is such that relative rotation of the first and second rotary members (31, 15) causes the clamping means (13) to move between the clamping position and the retracted position.

Abstract: A method and apparatus for exciting slices of an object in an NMR device in a specific order. N slices are indexed from 0 to (N-1). An integer X relatively prime to N is selected and the finite sequence l o +kX, k=0,...,(N-1)is generated where l o  is a selected integer. The least positive residue r k satisfying r k = l o +kX(Mod N) is calculated and then the slice S rk  is excited before the slice Sr (k+1  ) for k=0,....(N-2).The method and apparatus disclosed ensures that slices are excited in an order which reduces the resonant signal contamination present in a slice from the excitation of previously excited slices.

Abstract: Nucleic acid sequences are detected by a multi-step process, involving labeling sample nucleic acid sequences, duplexing the labeled sample with a probe having a coupling element, immobilizing all of the duplexed probe and target sequence and unduplexed probe, separating specifically immobilized nucleic acid from free and non-specifically immobilized nucleic acid, releasing specifically immobilized nucleic acid, and detecting the presence of the sequence of interest by means of the label. The labeled sequence may be characterized by sizing, e.g. electrophoresis. The method provide for a sensitive and rapid means for accurate detection of sequence of interest in a wide variety of situations.

Abstract: The supporting device for hairdresser apparatus has a basic parallelogram, which is mounted on the base and can be swivelled towards the vertical plane, and an attachment parallelogram which is connected to said basic parallelogram, can be swivelled about the horizontal plane and bears the hairdresser apparatus. The short links of these parallelograms are arranged in each case in such an oblique position that the parallelograms are rectangles in the central position of their swivel ranges which they assume most frequently during operation and thus have their greatest width and stability. Furthermore, during the swivelling of the basic parallelogram a cam guide mechanism ensures that the swivel movement of the attachment parallelogram is co-ordinated therewith so that a horizontal movement of the hairdresser apparatus is thus enforced. <IMAGE>

Abstract: An improved control apparatus for an engine having an auto-choking capability is offered by interlock­ing a choke lever (101b) and a throttle lever (101a) of a carburettor through a temperature-sensitive interlocking rod (102). A choke lever of a carburettor is provided with a spring (120) for resiliently biasing a choke in the opening direction. The choke lever and the throttle lever are connected with each other via a choke interlocking rod made of high molec­ular material such as high molecular urethane elastomer or the like, whose buckling force varies depending upon a temperature. Upon full opening of the throttle valve (130) at the time of cold state starting of the engine, the choke interlocking rod interlocks so as to close the choke (131). Whereas, at the time of hot state starting and warming up of the engine, it interlocks so as to open the choke owing to the resilient biasing action of the spring. A speed regulating device is connected to the throttle lever.
