Title: Mist reduction assembly for ink jet printers
Inventor: OBERTEUFFER JOHN A
IPC: B41J2/20
Filed: 1986-12-10
Abstract: The present assembly is an ink jet printer of the continuous stream type for printing an image on a recording surface having a nozzle or orifice from which an electrically conductive ink stream is expelled by pressure along a predetermined path toward a recording surface apparatus to selectively deflect or interrupt portions of the ink stream such that the portions deflected or interrupt are prevented from reaching the area of the recording surface or which said image is printed, an ink mist shield positioned proximate to the recording surface, the mist shield being maintained at a first potential, apparatus for charging the recording surface to a second potential substantially different from the first potential whereby ink which impinges the recording surface is charged thereby and particles of the impinging ink which rebound from the recording surface are impelled toward the mist shield by the field resulting from the difference between the first and second potential. The present method, for use in a continuous stream ink jet printer for printing an image on a recording surface having a nozzle or orifice and a recording surface, and a mist shield positioned proximate to the recording surface, is the steps of expelling by pressure a continuous stream of electrically conductive ink from the nozzle toward the recording surface, selectively deflecting or interrupt portions of the ink stream, applying an electrical charge to the recording surface, such that an electrical field exists between said mist shield and said recording surface whereby particles of the ink stream which rebound upon impact with the recording surface are urged toward the mist shield.

Title: Mechanism for operating a metering valve
IPC: G01F13/00
Filed: 1987-11-03
Abstract: A metering valve comprised of two rotary registers are each provided with cutouts which are symmetrical in relation to the axis of the central opening defined by the movement of the registers. In accordance with the present invention, a mechanism for operating the registers synchronously and in opposite directions is composed of levers and connecting rods acting on the axis of suspension and rotation of the registers through the action of, for example, hydraulic jacks. In order to avoid the offsetting of the flow because of the difference between the radii of curvature of the registers, one of the connecting rods acting on the axis of the registers is adjustable in length.

Title: Traffic hot spot locating method.
Inventor: VAARA TOMI
IPC: H04W24/00
Filed: 1997-09-30
Abstract: The present invention relates to a method and an arrangement for determining a hot spot of telephone traffic in a cell. The invention uses simultaneously two basic measurements of digital radio systems; timing advance and adjacent cell measurement. Timing advance informs the distance of the mobile station from the base station but not the direction. On the basis of the measured signal strengths of adjacent cells it is possible to determine a set of possible locations of the mobile station when there is information about the coverage area of individual adjacent cells. When these measurements are used simultaneously, they exclude the inaccuracies of each other and enable very accurate location determination for monitoring traffic distribution. Timing advance is utilized to determine a set of circular, base-station-centric areas and adjacent cell measurements are utilized to determine the direction of the mobile station to the base

Title: Process for making particulate compositions
Inventor: BEDELLS ALISON DAWN
IPC: B01J2/00
Filed: 1998-04-29
Abstract: There is described a process for producing a particulate composition comprising the steps of:(a) forming a first dispersion comprising first particles stabilised in a first fluid by a first species in an initial state, the first species changeable between the initial state and a further state, where the initial state provides (directly or indirectly) more stability to the particles within the dispersion than the further state;(b) optionally the step of forming a second dispersion comprising second particles stabilised in a second fluid, miscible with the first fluid, by a second species in the, or another, initial state, the second species also changeable between the, or another ,initial state and the, or another, further state, where said initial state provides (directly or indirectly) more stability to the particles within the dispersion than said further state;(c) after the optional step of mixing the first and second dispersions together if the second dispersion was formed in step b), changing the state(s) of the first and/or optionally second species from the initial state(s) to the further state(s) substantially to induce association between the dispersed particles to form clusters; and(d) binding together the particles within the clusters.A preferred embodiment of the process comprises mixing together two aqueous dispersions of particles (e.g. pigment particles with particles of latex polymer formed by emulsion polymerisation). The dispersions are stabilised by ionic surfactants of same sign charge. Association of the particles into clusters is induced by adjusting pH to selectively protonate or deprotonate the surfactants. The clusters are grown by aggregation into loose matrices which are fused together to form particles which can be used in electroreprographic toners.

Title: Voice over internet protocol systems
Inventor: MARSDEN STUART
IPC: H04L69/40
Filed: 2006-11-17
Granted: 2011-11-09
Abstract: A VoIP system comprises a VoIP unit for connecting a handset to a network, a router (eg ADSL router 1, figure 1) for connection to the Internet and at least two VoIP servers 42, 43 on different ports. Upon detection of failure in the communications between the VoIP unit and a first VoIP server 42, the VoIP unit is arranged to switch to a different port and thus use a backup VoIP server 43. The VoIP unit may be arranged to periodically connect with a web server (12, fig.3) in order to receive updates for firmware or hardware, or for other types of requests, and it may also frequently contact the VoIP server over a selected port in order to keep port mapping alive (NAT keep-alive). Failure of communications between the VoIP unit and the VoIP server may thus be detected upon the condition that the web server continues to receive communications whilst the VoIP server does not. Detection of such a condition would suggest that the VoIP unit was powered up (since it was still communicating with the web server) but that communications on the first port were faulty. Switching from the first port to the second port may thus be used to circumvent this fault. The VoIP unit may be arranged to periodically alternate between the two servers, switching more frequently when further errors are detected. Alternatively, the VoIP unit may switch from a first to a second server during periods of time when the first server is known to perform backups.
