Title: Queue management of ATM cells capable of controlling jitter as well as cell priority
Inventor: KIM DEOG-NYOUN
IPC: H04L47/56
Filed: 1998-04-28
Abstract: In a queue management system for selectively transmitting cells received from a plurality of sources, cells are queued for transmission according to priority information contained in a priority field of each cell. The priority information comprises a deadline time defined as a maximum allowable delay bound at a node, and an eligible time referring to a delay bound in which a cell is supposed to be transmitted from a node, determined by taking into account a jitter. A cell with a smaller deadline time has a higher priority. If deadline times are equal, a cell with a smaller eligible time has a higher priority. The system comprises a cell pool 32 for storing cells received via multiplexer 31, a FIFO 34 for storing empty sectors of the cell pool, a sequencer 33 for determining the cells' sequence of transmission according to the priority information and a read controller 36 and write controller 35 for accessing the multiplexer, cell pool and sequencer.

Title: A microscope and a method of manufacturing and operating such a microscope
Inventor: OLDFIELD HARRY
IPC: G02B21/06
Filed: 1998-11-09
Abstract: A microscope includes an illumination source, where the illumination source comprises a source (10) of polychromatic light (15), and means for selecting a combination of frequencies from among the frequencies of the polychromatic light, at selected respective relative intensities to one another, in order to provide non-white polychromatic light for illuminating a subject (25). The frequencies which are selected may be varied, and the relative intensities of the selected frequencies may also be varied. A diffraction grating (50) may be used to select, at least in part, the selected frequencies at the selected relative intensities, and these selected frequencies may then pass through an aperture (23) which may be variable in size to vary the selection of frequencies and/or relative intensities. The selection of frequencies may also be varied by altering the angle of incidence (a) of light upon the diffraction grating (50). A prism (60, fig. 3) may also be used in the place of a diffraction grating (50) in the frequency selection process. The source of polychromatic light may be a source of white light, which may be provided by an incandescent light bulb, or alternatively, the source of polychromatic light may be 3 differently coloured lights (10A-C, fig. 4).

Title: Bearing capacity enhancement for piling applications
Inventor: ENGLAND MELVIN GERRARD
IPC: E02D5/36
Filed: 1999-04-09
Abstract: A piling auger (1) includes a fixedly mounted element (5) which is arranged so as to extend beyond the circumference of the flight (3) of the auger (1). The element (5) is configured so that when the auger (1) is first rotated in a given direction and allowed to penetrate the ground to a predetermined depth, a first spatial volume is swept out by the element (5), and when the auger is withdrawn from the ground with continued rotation in the given direction and with concomitant supply of concrete or grout to the tip (4) of the auger (1) a second spatial volume is swept out by the element, the second volume being greater than the first volume. In this way, a pile having a circumferential helical concrete or grout projection is formed without undue disturbance to the surrounding soil during penetration, thereby enhancing the end bearing capacity and skin friction of the resulting pile. The element (5) can also be mounted onto a cutting tooth.

Title: Process for the lowering of the oxidation state of metal salts
IPC: C22B3/00
Filed: 1982-06-01
Abstract: The oxidation state of metal salts is lowered by contacting a solution of the salt with polyacetylene in the presence of sufficient moisture to leave the polyacetylene substantially undoped. The metal salt must have a reductive capacity of at least +0.5. This process can be used to reduce metal salts to zero active valency metal. The moisture is effectively added by treating an aqueous solution of the salt, optionally with organic cosolvent. The zero valency metal can subsequently be recovered from the polyacetylene, for example by burning the polyacetylene off.
