Abstract: A simple and precise method of controlling the gap position (obliqueness and height) of magnetic recording installations with n tracks (n=1, 2 . . . ) is obtained by subdividing at least one track of a recording tape into two auxiliary tracks in accordance with the given recording format, which auxiliary tracks are recorded at the center to center track distance of d, using a special head with correct gap position. The recording wave length and magnetization are preferably equal due to the width of the auxiliary tracks being equal. The auxiliary track 1 is recorded continuously while the auxilary track 2 is recorded at time intervals with a signal of equal magnitude but with different phase angles. Each time interval has a phase angle associated with it. The magnitude of correction of the gap required can easily be determined from a graph showing the voltage level difference measured at two different phase positions. The oblique angle of the gap may be measured and corrected by these means and in one variation of the invention the height adjustment of the head can also be measured and corrected.

Abstract: A novel retinoic acid receptor is disclosed. The novel receptor is encoded for by cDNA carried on plasmid phRAR1, which has been deposited with the American Type Culture Collection for patent purposes. Chimeric receptor proteins are also disclosed. The chimera are constructed by exchanging functional domains between the glucocorticoid, the mineralocorticoid, the estrogen-related, the thyroid and the retinoic acid receptors. In addition, a novel method for identifying functional ligands for receptor proteins is disclosed. The method, which takes advantage of the modular structure of the hormone receptors and the idea that the functional domains may be interchangeable, replaces the DNA-binding domain of a putative novel receptor with the DNA-binding domain of a known receptor such as the glucocorticoid receptor. The resulting chimeric construction, when expressed in cells, produces a hybrid receptor whose activation of a ligand-(e.g., glucocorticoid) inducible promoter is dependent on the presence of the new ligand. The novel method is illustrated in part by showing that the ligand for the new receptor protein is the retinoid, retinoic acid. <IMAGE>

Abstract: An analog baseband signal (32) modulates a reference frequency carrier signal (38) to provide a double sideband, suppressed-carrier DSB-SC signal. The DSC-SC signal is converted in a voltage-to-frequency converter (54) to a series of pulses, the repetition rate of which is proportional to the level of the DSB-SC signal. The output signal of the voltage-to-frequency converter is demodulated to produce a digitally formatted version (62) of the baseband signal. A notch filter to reflect an undesired signal is provided as a feedback path from the output voltage-to-frequency converter (54) to a negative input of a summer (48) in the input line of the DSB-SC signal. The feedback path converts the frequency signal from converter (54) to a cancellation signal having the format of the undesired signal.

Abstract: A file system for managing data files for access by a plurality of users of a data processing system that includes internal storage for buffering, external storage, and a file user interface by which the plurality of users request access to data files. A first level, coupled to the file user interface in the internal storage allocates the internal storage for temporary storage of data to be accessed by the plurality of users, and generates requests for transactions with external storage in support of such allocations. A second level is coupled to the first level and the external storage and responds to the request for transactions with the external storage for managing the transactions for storage of data to, and retrieval of data from, the external storage. The second level defines a plurality of physical storage classes which are characterized by pre-specified parameters that allocate data files subject of transactions to locations in external memory. In response to requests for transactions, the second level identifies one of the plurality of storage classes assigned to the data file subject of the transaction and carries out the transaction with the appropriate locations in external memory. At least one of the plurality of storage classes provides for utilization of a plurality of access paths in parallel for transactions involving data files assigned to such storage class. Further, at least one parameter pre-specified for storage classes identifies a level of reliability desired for the subject data files.

The two opposing contact points of the tensioned cable on the tool carriage (1) are designed as rockers (20, 21), which neutralize the different tensile forces of the individual cables. Repetitive accuracy in plotter tool positioning is thereby improved.

Abstract: The present invention provides a simple process for the production of anhydrous oxime by the separation of the oxime from an aqueous solution. The process is advantageous because the potential explosive hazards of current processes are eliminated and the oxime is easily separated from the aqueous phase. The process comprises the steps of: (a) vaporizing an aqueous oxime solution; (b) vaporizing a water-immiscible organic solvent for the oxime wherein the boiling point of the solvent is lower than the boiling point of the oxime; (c) combining the vapors together; (d) condensing the collected vapors; (e) removing the organic phase of the condensate from the aqueous phase; and (f) recovering anhydrous oxime from the removed organic phase. The anhydrous oxime produced by the present process is useful in applications such as isocyanate condensation and carbamate formation.

Abstract: An arrangement in shelf, tray, drawer structures (10) or like structures of the kind which can be moved between an inserted position, for the storage of articles, e.g. packages such as drugstore packages, and a position of use in which the packages can be removed from the trays or the like. The trays or the like are mounted on brackets (12) which are fitted to a frame structure (22) in a manner to enable the brackets to be adjusted between mutually different positions, and optionally to be removed from the frame structure. The trays, drawers or the like include catch means (36) which are intended to latch the trays or the like in a fully inserted position in the brackets (12). The brackets (12) can be adjusted on the frame structures (22) such as to extend horizontally or at an inclined angle. The trays or drawers and/or the brackets are configured so that when the brackets (12) are in their horizontal positions the trays or drawers cannot be inserted to their full extent, thereby preventing the catch means (36) from coming into operation. This can be achieved, for instance, by inclining the end wall surface of respective trays, such that the end wall will slope obliquely inwards to the structure (22) from the bottom of respective trays to their upper side. When the brackets (12) are adjusted to their inclined positions, the trays or the like (10) can be fully inserted and thus latched by the catch means (36).
