Abstract: ABSTRACT OF THE DISCLOSURE          A digital signal recording/reproducing apparatus capable of recording and reproducing digital signals having differences in respect to sampling frequency thereof and the number of quantization bits per sample by means of a common circuit arrangement includes means for varying revolution speed of rotating heads for record-ing and reproduction or traveling speed of a recording medium as a function of different sampling frequencies.          A signal processing circuit for processing the digital signals so as to be suited for the recording on the recording medium is controlled by a clock signal of which frequency is changed in dependence on the different sampling frequencies.  The signal processing circuit is arranged so that PCM data contained in a frame is constituted by a number of bits which is equal to a common multiple of the different quantization bit numbers and added with a common frame synchronizing signal and common error detection and correction codes to thereby prepare the PCM signal of the frame arrangement.  The digital signals which differ in the sampling frequency and the quantization bit numbers can be recorded by same recording and reproducing apparatus with an improved efficiency with a same wavelength and in a same signal format.

Abstract: Abstract of the Disclosure Synchronization of a source of computer controlled video to a video disc player for interactive application is obtained by sensing when the computer vertical sync leads that of the player and gating out a number of computer clock pulses equaling one video line during a period of one or more video lines.  Horizontal synchronization is disabled during the vertical acquisition mode and then is established by modulating the computer clock frequency with a line rate phase error signal obtained from both video sources thereby providing rapid synchronization within approximately two seconds under worst case conditions.

Abstract: Abstract of the Disclosure Disclosed is a composition including a water swellable clay, and particularly a montmorillonite clay, such as bentonite; xanthan gum; and one or more additional water-soluble gums, for example, guar, dextran, acacia or locust bean.  The xanthan gum to-gether with one or more additional water-soluble gums prevents montmorillonite clay composition from sub-stantial coagulation or flocculation upon contact with salt contaminated water even in high concentra-tions of, for example, 15-40% by weight salt.  It has been found that xanthan gum in an amount of 0.1-20% based on the weight of the water-swellable clay, i.e. bentonite, in the composition together with one other water soluble gum, for example guar gum, dextran gum, acacia gum and/or locust bean gum in an amount of 1.0-10% based on the weight of bentonite in the compo-sition will provide a clay composition capable of excellent stability without component separation in salt contaminated water. The composition is par-ticularly useful as an additive to compositions used as stable drilling fluids in rotary drilling, and as lagoon and landfill sealants.

Abstract: ABSTRACT             STEERING HANDLE FOR LUGGAGE CASE      A luggage case is provided with a steering handle (15) for steering the case when it is being rolled on the ground.  The handle (15) is pivoted to the case shell (19) by means of a pivot pin (20) for movement between a closed position in which the handle (15) lies adjacent the shell (19) and an extended position in which the handle projects from the shell.  Movement of the handle (15) away from the closed position is limited by means of a stay (23) connected between the case shell (19) and a position on the steering handle (15) spaced from the pivot pin (20) towards the free end of the handle (15).  The stay (23) is of resilient flexible material.  The base moulding (17) of the handle is provided with a projection (32) which holds the stay (23) in a flexed condition when the handle (15) is in the closed position so that the stay (23) exerts a force on the handle tending to hold the handle (15) in the closed position. Thus, the need for a separate spring to hold the handle in the closed position is avoided.

Abstract: ABSTRACT: "Method and device for determining an NMR distribution in a region of a body."           The method and the device for making NMR images in accor-dance with the invention utilize additional measurements and addi-tional calculations in order to achieve a substantial reduction of image artefacts caused by (respiratory) motion of the body. The additional measurements involve the sampling of the non-conditioned FID or spin echo signal which can (but need not) be performed during each measurement cycle without consuming a substantial amount of additional measurement time. The non-conditioned signal samples are used to derive a reference frequency spectrum which is a measure of the size of the object. By comparing this reference with the fre-quency spectra of the various measurement cycles, standardization is obtained so that image signals produce an unambiguous image even though they have been derived from signal samples taken from measure-ment cycles performed in different states of motion (different object size).

Abstract: ABSTRACT OF THE DISCLOSURE         A management system utilizes a distributed network having a host computer connected to one or more computer based workstations.  Separate, on-line software support systems provide the execution environment for the system.  Each support system provides data that reflects one or more aspects of a life cycle of a development project.  This data is stored in separate databases associated with each support system.          Periodically, the host computer extracts information from each of these support system databases to obtain data indicative of development activity for various phases of the life cycle of the software system.  The extracted information is used to update a relational database.  At any time, a manager situated at a workstation can formulate queries into the relational database.  Thereafter, the workstation, through a workstation/host communications interface, initiates a host session and then loads the queries into the host computer.  The host, in turn, executes these queries and downloads the query results into the workstation.  Then the manager appropriately analyzes and interprets those query results at the workstation.          The communications interface ensures that the host session remains substantially transparent to the manager.  This advantageously frees the manager of any need to learn the host logon procedure and operating system, thereby minimizing the managerial time and effort required to obtain the desired information.
