Title: Mechanical torque indicator
Inventor: THOMPSON PARKE H III
IPC: B25B23/14
Filed: 1993-08-31
Abstract: A mechanical torque indicator apparatus (20) for use in gauging and indicating the magnitude of torsional force exerted on a driven member (18) by a torque drive member (16) includes an elongated torsion member (26) defining a longitudinal axis and having first and second axial ends. The torsion member (26) is supported on the torque drive member (16) so that torsion loading of the driven member (18) is transmitted through the torsion member (26). The relative rotational displacement of the axial ends of the torsion member (26) is converted by the apparatus (20) into bi-directional linear displacement carried out within a plane transverse to the longitudinal axis. This linear displacement actuates an indicator (38) mounted on the torsion member (26) for providing an indication of the applied torque.

Abstract: An improved reinforced laminate for use in sails or other flexible sheet or membrane applications utilizes a pull-truded thin lightweight reinforcing sheet of unidirectional extruded monofilaments in which the reinforcing sheet or sheets (32, 34, 36) form one or more uni-tapes laminated to a polymer film (40) such as Mylar®, or other extended sheet of material. The monofil-aments (38) are uniformly embedded in the uni-tape via an elastomeric polymer matrix, with the reinforcing sheet, when in-corporated into sails via lamination resulting in sails with reinforcing monofilaments having diameters 5 times less than conventional strands or threads. The use of small diameter monofilaments greatly increases the monofilament-over-mono-filament crossover density, resulting in a dramatic increase in shear strength, and Young's Modulus, with an accompanying dramatic decrease in weight. In one embodiment the improvement in specific modulus over conventional sail laminates is about six-fold. For example, at only one-third the weight, stretch resistance is two times better. In a preferred embodiment, autoclaving is used in the lamination process to rid the laminate of voids which dramatically reduce shear strength by as much as 30 percent. Alternative void-free laminating processes include a silicone interliner/heated platen technique.

Title: Movable rolling storage system
Inventor: FRANCIS DENNIS
IPC: A47B96/00
Filed: 1995-06-05
Abstract: The  present  invention provides a  movable  rolling storage system that maintains extremely tight tolerances and quality control,  yet it can be manufactured at  low cost with very short delivery times.  The storage system is shipped from the factory to the installation site  in containers with the various required factory  fabricated sub-assemblies,  of such volumes and weights,  that  the shipping cost is most economical and the containers  are readily  moveable through standard office building  door openings  by  site  installation  personnel.    The  sub assemblies   are  assembled  at  site  by  non   skilled personnel,  using  only a few simple tools,  to  form  a rigid frame that holds the rails at its precise parallel design distance.   The only measurement necessary is the initial  non critical tolerance distance from the  wall.          The invention provides a track/rail frame with  frequent levelling screws,  that can be adjusted under full load, on  both sides of the track/rail such that  both  height and camber can be set.   The movable carriages are  also assembled by non skilled personnel into a rigid frame to which the shelves or racks are attached.   The wheels of the  movable carriage are suspended such that they  will self align to the rails,  making installation and future alignment   maintenance unnecessary.    The   invention includes  safety  features such as anti  tip  preventers under  each  wheel  and  a  locking  device  to  prevent accidental  movement  of  the  mobile  carriages   while personnel are in the access aisle.

Title: Means for displaying photographs
Inventor: FERDINANDSEN BENDIX MILAN
IPC: B44F1/00
Filed: 1994-01-11
Abstract: A mask (1) is adapted for superimposing on a photo carrying a motif in form of e.g. a portrait (7) that is to be accentuated. The mask is made of a transparent plastics foil as by means of e.g. coloured raster is made opaque in a peripheral region (2) surrounding a transparent, central area (3) without raster. The peripheral region (2) and the central area (3) is separated by a relatively narrow, transitional zone (4) with increasing distance between the raster so as the transitional zone gradually fades out into the transparent, central area (3). The mask may be employed in the same simple manner as a passe-partout frame for accentuating one particular motif on a photo, and with the same good visual effect achieved by a traditionally phototechnical method for integrally to provide a photo with a neutral peripheral region gradually fading out via a soft transitional zone into the desired motif.

Abstract: Taxol TM is a complex diterpene which is currently considered the most exciting lead in cancer chemotherapy.      Taxol possesses high cytotoxicity and strong antitumor activity against different cancers which have not been effectively treated by existing antitumor drugs. However, Taxol has a problem with solubility in aqueous media, which may impose some serious limitation in its use. Taxotere seems to have antitumor activity superior to Taxol with better bioavailability. Taxotere has a modified Taxol structure with a modified C-13 side chain. This fact strongly indicates that modification on the C-13 side chain would provide a new series of Taxol and Taxotere analogues which may have higher potency, better bioavailability and less unwanted toxicity. The present invention provides efficient and practical methods for the syntheses of Taxotere and its analogues of the formula: (see formula I) through .beta.-lactam intermediates of the formula: (see formula II) and their coupling with a metal alkoxide baccatin III derivative of formula: (see formula III)

Title: Broadband switching network
Inventor: SMITH AVRIL JOY
IPC: H04L12/54
Filed: 1995-03-08
Abstract: In a broadband switching system for the switching of asynchronously transferred cells of data, a dynamic bandwidth controller (DBC) controls the application of data cells to an input port of the system, the data cells being supplied by a number of transmitting end systems.  The DBC provides buffering for cells from each source and controls the output of data cells to the system according to a current cell rate (CR) assigned to cells from the respective end system. When an end system begins transmitting data cells, the DBC detects the presence of incoming cells and requests bandwidth from a connection admission control (CAC) forming part of the system whilst providing a default cell rate for the end system so that transmission can continue until an appropriate bandwidth is allocated. The DBC contains a buffer for buffering cells in this situation. Once appropriate bandwidth has been allocated, cell rate advice information from the CAC is fed back to the DBC and thence to the transmitting end system to prevent the transmission of cells at too high a rate for the available bandwidth. The invention has both apparatus and method aspects.
