Title: Method for optimized tape tension adjustment for a tape drive
Inventor: STEINBERG MITCHELL R
IPC: G11B15/43
Filed: 1992-04-14
Abstract: A method for selecting an optimal operating tension of a motor driven tape in a tape drive is disclosed. The tape is loaded into the tape drive. A test signal is applied to record test information onto the tape while the tape tension is varied concurrently in a prescribed manner for testing. The recorded test information is read immediately to provide a test readback signal. The test readback signal is processed to determine a functional relationship between the test readback signal and the varying tape tension. An operating tape tension value is selected based upon the functional relationship. The selected operating tape tension is implemented on the tape drive in the form of a command signal to a motor means of the tape drive.

Title: Preparation of thionucleosides
Inventor: YOUNG ROBERT JOHN
IPC: C07D409/04
Filed: 1992-04-28
Abstract: The invention relates to the preparation of homochiral thiolactones which have application in the synthesis of 3′- and 4′- thionucleosides. Substituents on the thiolactone can be used to influence the configuration of the C-1′ position in the final nucleoside. Configuration at the C-4′ position is controlled by use of the appropriate homochiral glycidol as starting material in the synthesis of the thiolactone. This process also offers the possibility of introducing substituents diastereoselectively in the C-2′ and C-3′ positions.

Abstract: A waste gas burner (10) comprises burner means (12) into which waste gas is fed through injectors (15), each leading to an open end of a conduit (17) to cause natural aspiration of primary air (20). The primary combustion takes place in a reaction zone (19) surrounded by a peripheral wall (16) which is pierced by ducts (23) so as to introduce recirculated combustion products under natural draught. Secondary air intakes (25) surround the peripheral wall (16) of the reaction zone (19) and promotes secondary burning of the recirculated gases. The reaction zone has a high temperature short duration combustion without excess air and the secondary combustion takes place at a lower temperature with a longer retention time and in the presence of excess air so as to reduce nitrogen oxide formation and ensure combustion of impurities in the waste gas.

Abstract: A rolling mill has a work roll (1), a back-up roll (2) for supporting the work roll (1) vertically and driving it. A plurality of horizontal support rollers (4,6) contact the work roll at barrel diameter outside the rolling region and at both horizontal sides of the work roll and act to fix the position of the work roll in both horizontal directions during rolling and to oppose horizontal rolling forces. In order to reduce the bending of the work roll during rolling, there are provided means for applying horizontal counterbending forces to the work roll comprising members (5,7) e.g. rollers, contacting the work roll at locations axially further from the rolling region than the support rollers (4,6) and actuator means (14) for urging the members (5,7) against the work roll. The counterbending forces being in the same direction as the net horizontal force applied to said work roll by said back-up roll and the material being rolled. Preferably at least one condition of said work roll is sensed during rolling, and there are control means acting during rolling to control the counterbending forces in dependence on the sensed condition.

Abstract: The present invention provides a sinusoidal wave signal generating circuit which makes it possible to reduce the circuit scale. Only the sinusoidal wave amplitude data are stored by relying upon the symmetry of the sinusoidal wave form for outputting sinusoidal wave amplitude data corresponding to input phase data. When the phase data other than the stored phase in the quarter other than the stored phase in the quarter of one period is input, the input data is converted to a relevant phase data in a quarter of one period so that the sinusoidal wave amplitude data in one period can be output.

Abstract: A novel intermediate useful in the synthesis of ethylenediaminetriacetic acid (ED3A) or its salts. A salt of N,N′-ethylenediaminediacetic acid (ED2AH₂) is condensed with formaldehyde to form a stable 5-membered ring intermediate. The addition of cyanide across this cyclic material forms ethylenediamine N,N′-diacetic acid-N′-cyanomethyl or salts thereof (mononitrile-diacid), which is a useful intermediate in the production of ED3A. The nitrile in aqueous solutions may be spontaneously cyclized to form 2-oxo-1,4-piperazinediacetic acid (3KP) or salts thereof. In the presence of excess base, salts of ED3A are formed in excellent yield and purity.

Abstract: An apparatus and method for improving the input/output performance of a redundant storage array system. The present invention provides a "special parity" cache within the controller for a redundant storage array system, and means for determining and caching a quantity known as the "remaining redundancy row parity" (RRR-parity) block. The RRR-parity block is equal to the old parity block of a redundancy row XOR'd with an old data block being read from the same redundancy row. By caching RRR-parity blocks, Write-intensive storage unit operations can be reduced by up to three input/output accesses.
