Patent GB-2256497-A (GB)
Title: Green toner
Inventor: CICCARELLI ROGER N
IPC: G03G9/09
Filed: 1992-05-28
Abstract: A green toner comprises resin particles, green pigment particles, a charge enhancing additive, and surface additive particles. Preferably the green pigment is halogenated copper phthalocyanine which is negatively charged and a positive charge enhancer is used to produce a passivated toner. Alternatively, a positive charging green pigment such as a triarylmethane and a negative charge enhancer may be used or a mixture of blue and yellow pigments may be used for the green pigment. The green toner is preferably mixed with a carrier and used in a two-colour imaging process as in US4078929 but with a black developer, the green toner developing areas of low potential and the black toner developing areas of high potential.

Title: Rail platform observation system.
Inventor: BIRKIN MICHAEL SAMBROOK
IPC: H04N7/081
Filed: 1992-06-20
Abstract: A communication system for communicating door operating information to trains having remotely operated doors on both sides is incorporated into a closed circuit television system normally used to enable the train driver to view on his in- cab display monitor the platform into which the train has run. The door operating information is transmitted as part of the television transmission, for example by digitally encoded signals during the field blanking interval or by a separate modulated carrier. The information is separately detected and used to provide the driver with a visual or audible signal of the correct door opening side and/or to control the door operating system so that the doors can only be opened on the correct side. <IMAGE>

Title: Flue gas conditioning system
Inventor: LYNCH JEROME G
IPC: F23J15/00
Filed: 1992-02-03
Abstract: A gas conditioning system for reducing the electrical resistance of finely-divided fly ash particles entrained within a flue gas stream resulting from the burning of low sulfur coal and for enhancing the removal of the fly ash particles by electrostatic precipitation (12) wherein an acid conditioning agent, e.g., sulfuric acid, is passed through a vaporizing coil (25) mounted within an enclosure defining a mixing chamber (24) downstream from said coil and is vaporized by a stream of hot air (29) passing over said coil (25) and into said mixing chamber (34). The vaporized acid exits the coil (25) and mixes with the hot air in the mixing chamber (24) and the resulting mixture is injected into the flue gas stream so that the acid vapor can condense on the fly ash particles. <IMAGE>

Title: Information retrieval in a distributed database management system.
Inventor: DU WEIMIN
IPC: G06F17/30
Filed: 1993-08-09
Abstract: A system and method for managing electronic data access among multiple different relational databases in a network distributed database environment. The system can construct cost-effective access strategies for any of the participating databases using DBMS-specific cost models. The system provides query optimization across different database management systems based on a calibrating database. Cost data is developed by running queries in the various databases against the calibrating database. A logical cost model is constructed using the resulting cost data and is used to estimate the cost of a given query based on logical characteristics of the DBMS, the relations, and the query itself. The cost of a complex query is estimated using primitive queries. <IMAGE>

Title: Fingerprint verification system
Inventor: TOMKO GEORGE J
IPC: G06K9/00
Filed: 1993-09-13
Abstract: A fingerprint verification system is used as a fast and effective security device to verify that an applicant to a service protected by the system is authorized to use the system. Electronic information allowing the creation of a correlation filter on a spatial light modulator (SLM) 26 is input from a smart card 10 or fingerprint database. The fingerprint or cluster of fingerprints of the applicant are then correlated through the SLM 26 in order to derive a comparison with those electronically stored. Although the system uses electronically stored pattern information, the correlation is performed optically. <IMAGE>

Title: Vibration measurement system for a rolling bearing
Inventor: MATSUZAKI HIROYUKI
IPC: G01M13/04
Filed: 1995-04-06
Abstract: A vibration measurement system (1) comprises a shrink-type chuck (5), a spindle (14), and a servo motor (16) as mechanical elements, and has a vibration pickup (41) attached to the outer peripheral surface of a jaw (5a) holding an outer ring (4) of a roller bearing (2).
