Abstract: A link conveyor for an assembly machine and methods for chordal compensation in a link conveyor, may include a first upper chordal compensation cam in the upper rail assembly at the first end of the frame to deflect the chain by a first upper variable deflection amount; a first lower chordal compensation cam in the lower rail assembly at the first end of the frame to deflect the chain by a first lower variable deflection amount; and configuring the first upper variable deflection amount and the first lower variable deflection amount to reduce deviation between a first velocity of the chain at the first end of the frame and a second velocity of the chain at the second end of the frame.

Abstract: A coupler 001 has a central section 006 with a rotation axis 007 and arms 003 which extend away from said central section 006. The arms 003 are in an offset location relative to a diametrical line 060. A portion 004 of the arms 003 meets or passes through or extends along a plane formed through the diametrical line 060 and the rotation axis 007. Also included is an appliance using such couplers and a drive mechanism using such couplers.

Abstract: An ion mobility spectrometer or other ion apparatus has two or three grid electrodes 51 and 52; 151 to 153; 106 and 107; 106? and 107? extending laterally of the ion flowpath. An asymmetric waveform with a dc compensating voltage is applied between the electrodes to produce a field parallel to the ion flow path that affects ions differently according to their field-dependent mobility. This filters or delays different ions selectively in their passage to an ion detector 11, 111, 111? to facilitate discrimination between ions that would otherwise produce a similar output.

Abstract: A FAIMS ion mobility spectrometer is arranged so that the analyte is subject to different ion chemistries at different locations along the spectrometer. Different dopants, or different concentrations of dopants or water vapor are admitted at various locations, such as at the inlet, between the inlet and the ionizer between the ionizer and the gate, between the gate and the FAIMS parallel plates, through an opening in one of the plates, or between the end of the plates and the detector.

Abstract: A remote testing system employs digital fingerprinting in order to recognize with a determined degree of certainty, multimedia content transmitted over a target communications network being tested, for example a cellular communications network, without requiring the transmission of a reference copy of the content to the comparison equipment.

Abstract: A system for managing a telecommunications network comprises a core part storing all objects used by the system as master copies, and at least one peripheral part containing applications stored in the user workstation, through which applications the services of the system are offered to the user, each peripheral part having separately stored copies of objects used by the applications of the peripheral part concerned. The actions made by an application and the changes resulting from said actions are recorded, and an indication of the actions is transmitted from the application to the core part. When the network to be managed sends an indication of a change, the indication is transmitted to those applications that have copies of the objects to which the change relates.

Abstract: In a system for managing a telecommunications network the transmission network to be managed is connected to the management system by means of interface processes in such a way that devices used in the network are classified into different device categories (MD, SXC, SDH), the system comprising for each device category an interface process (IPI-IP3) which converts a device belonging to the concerned device category so that it appears, as viewed from the direction of the management system, as a generic basic device corresponding to a device represented by corresponding objects within the management system.
