Title: Remote protection of three phase distribution transformers
Inventor: HAMPSON JOHN THOMAS
IPC: H02H3/44
Filed: 1990-06-08
Abstract: Remote digital protection of a distribution transformer is provided by a protection system able to detect increases in positive sequence current and increases in negative sequence current resulting from unbalanced disturbance on a distribution cable 10 feeding a transformer. The triggering of a circuit breaker 12 is then initiated to isolate the supply cable in response to a detected increase in negative sequence current only if there is a simultaneous detected increase in the positive sequence current in excess of a respective threshold increase. Phase currents and voltages are sampled and digitised 13, stored in a memory 18, and processed by a microcomputer 14. <IMAGE>

Title: Control of viscosity in sedimentation process
Inventor: GILCHRIST IAN CHRISTOPHER ROBE
IPC: B01D21/00
Filed: 1990-06-20
Abstract: A mathematical model representing a relationship between certain parameters, namely area product, viscosity and a parameter related to zeta-potential, e.g. PH, of an unevenly colloidally stable mixture is created. Zones in the model in which there is undesirably high viscosity 10 are identified and a model sedimentation path which skirts the high viscosity zones 16, 18, 20, 22 is superimposed on the model. The actual mixture under consideration is monitored during a sedimentation process to obtain actual measured values of any or all of the critical parameters. In the final step, the parameters are adjusted as necessary to fit actual measured values to values 24, 26, 28, 30 on the model sedimentation path. In this way the viscosity is reduced without undesirably high viscosity occurring during the sedimentation process. <IMAGE>

Title: Receiving encoded data
Inventor: COOPER ANDREW
IPC: H04B7/24
Filed: 1991-10-04
Abstract: A method of receiving data transmitted in a burst-mode radio communications such as GSM. Prior to transmission a set of first data elements (bits) relating to a first message which may be associated with a first channel type (e.g. a traffic channel (TCH) in GSM) has selected bits substituted or "stolen by data elements (bits) relating to a second message which may be associated with a second channel type (e.g. a fast associated channel FACCH in GSM). The data elements relating to the first and second messages are interleaved over the same or a different number of bursts. in a normal GSM traffic burst two single-bit flags are set to '1'. to indicate respectively when the even bits or the odd bits of the burst have been stolen for FACCH data. A detector (5) is used to monitor the flags from the same number of bursts over which the FACCH is interleaved. In order to improve the chance of detecting a FACCH in noisy conditions a majority-vote circuit (9) is employed whereby a FACCH decode is initiated if the number of detected flags set to '1' exceeds a threshold value. Specifically, in the case of FACCH, the threshold value may be 5-8, i.e more than half the number of bursts over which the FACCH data is interleaved. <IMAGE>

Title: X-ray analysis apparatus
Inventor: ARAI TOMOYA
IPC: G01N23/223
Filed: 1993-04-07
Abstract: An X-ray diffraction or total reflection fluorescent analysis apparatus includes an artificial multi-layered grating (1) for rendering X-ray beams (B1) to be monochromatic before they are incident on a specimen (2) to be analyzed. Grating (1) operates to diffract the X-ray beam (B1), generated from source (P) and subsequently impinging on reflective surface (1a) of the grating (1), at a predetermined angle of diffraction (8) to provide the monochromatic X-ray beams (B2). The periodicity (d) of the spacing of lattice planes of the artificial grating (1) is so chosen as to be of a value progressively varying along the reflective surface (1a) thereof with an increase in distance from the X-ray radiation source (P). The X-ray analysis apparatus avoids any possible reduction of the intensity of the monochromatic X-ray beams (B6) and increases the intensity of the X-ray beams (B6) to ensure an improved accuracy in spectroscopic analysis. <IMAGE>
