Title: Sleepers for Railway Track Systems
Inventor: HEIM ARMIN
IPC: E01B7/02
Filed: 1994-05-06
Abstract: The proposed device is a sleeper for railway track systems, suitable for incorporation in the track near points, more particularly near the drives and the associated tip fastenings for the points-tongues, which are adjustable via slide rods. The aim is to replace expensive manual operation by high-tech mechanised track construction using completely mechanised track-tamping machines, even near the points-tongue drive and the associated tip fastenings. To this end, the proposed sleeper is a box sleeper (1), characterised by a steel trough or box-like sleeper section member (5) which has a cross-sectional width (15) and a cross-sectional height (16) matching that of a normal concrete or wooden sleeper and has an open part (31) on top and is optionally closed or closable at its ends by transverse plates (17 and 18) and has laterally projecting bearing flanges (13 and 14) for stock-rail securing means (28, 29), points-tongue slide chairs (30) and/or operating components of tip fastenings, and the trough or box-like sleeper section member (5) is associated with tip fastenings in the form of "latch fastenings" (33) comprising stationary guides (32) and movable latches (34), cam rods (35) and cam-rod bearings (37), all of which project into the upper part (31) of the trough or box-like sleeper section member (5), whereas the bottom part houses the points-tongue slide rods (44), the tongue-monitoring linkage (45), heating rods (43) if any, and shock-absorbing elements (38). The open part (31) of the trough or box-like sleeper section member (5) is closable on top by releasably mounted covers which can be secured e. g. to the bearing flanges (13 and 14) of the trough or box-like sleeper section member (5) of the box sleeper (1).

Title: System and method for computer cursor control
Inventor: ROBERTSON KENNETH R
IPC: G06F3/0481
Filed: 1995-01-13
Abstract: A system determining an intended cursor location on the computer display screen and automatically repositions the cursor at the intended location. If the user selects a command that alters the contents of the display, such as opening a new window, the system analyzes the new screen display to determine whether there are user selectable options associated with the new screen display. The system determines if one of the user selectable options is a default option and automatically positions the cursor at the default option. If the new screen display is an application program, the system attempts to locate a user selectable option and repositions the cursor at the user selectable option. When the new window is closed, the system returns the cursor to the position it was at before the new window was opened. The system also predicts an intended location for a screen display that has not beenaltered, and automatically positions the cursor at the intended location. This feature can be selectively enabled to prevent the inadvertent repositioning of the cursor in the display.

Title: Oxidation of glycoside substituted taxanes to taxol or taxol precursors and new taxane compounds formed as intermediates
Inventor: MURRAY CHRISTOPHER K
IPC: A61K31/357
Filed: 1993-11-02
Abstract: A process for the conversion of glycoside substituted taxanes to taxol and related compounds that can serve as precursors to taxol. The process includes the oxidation of glycoside substituted taxanes to convert the glycoside to the hydroxyl group. The oxidation can occur in the presence of an acid or followed by treatment with acid. Application of the process to 7-xylosyl taxol ("XT") yields taxol; application to other glycoside substituted taxanes forms compounds that can serve as precursors for taxol. The process includes the formation of certain new taxol related intermediate compounds having a hemialdal at the C-7 site on the taxane ring, which hemialdal can then be converted to taxol or taxol precursors. Since glycoside substituted taxanes are isolated with taxol from naturally occurring biomass, their conversion to taxol using the process of the present invention significantly improves the total yield of taxol from natural sources.

Title: Method and apparatus for allocating memory to reduce conventional memory requirements
Inventor: ECHOLS GRANT G
IPC: G06F12/06
Filed: 1994-03-08
Abstract: The present invention provides an environment for DOS executable programs or "modules" that are constructed so that they can cooperate with other similarly constructed programs in sharing memory used by portions of their code or data. This reduces the overall requirements of conventional memory (102). The modules include transient code and data (403), that may be swapped out of conventional memory, and global code and data (402) that is not swappable and stays resident in conventional memory. The present invention reduces conventional memory requirements by allowing modules to share a single block of conventional memory for transient code and data. Instead of swapping transient blocks of modules to and from disk storage (204), the transient blocks are swapped between conventional memory and extended (111) or expanded memory (406). This significantly reduces transfer time compared to overlay schemes, improving performance.

Title: Method and apparatus for selecting an encoding rate in a variable rate vocoder
Inventor: DEJACO ANDREW P
IPC: G10L25/78
Filed: 1995-08-01
Abstract: The present invention provides a method by which to reduce the probality of coding low energy unvoiced speech as background noise. An encoding rate is determined by dividing the input signal into subbands using digital subband filters (4) and (6) and comparing the energy in those bands to a set of thresholds in subband rate decision elements (12) and (14) and then examining those comparisons in an encoding rate selector (16). By this method, unvoiced speech can be distinguished from background noise. The present invention, also, provides a means for setting the threshold levels using the signal to noise ratio of the input signal, and the present invention provides a method for coding music through a variable rate vocoder by examining the periodicity of the input signal to distinguish the music from background noise.
