Title: Method for setting the armature stroke at a relay
Inventor: STADLER HEINZ
IPC: H01H49/00
Filed: 1994-03-23
Abstract: ABSTRACT OF THE DISCLOSURE A contact spring having an interactive connection to an armature is brought into contacting contact with its respective cooperating contact element in a position corresponding to the working position of the armature. Subsequently, an excess stroke is exerted on the armature such that the desired contacting force is produced.  A fastening end of the respective contact spring is applied to a carrier in a position corresponding to the excess stroke and is joined thereto.   By setting the excess stroke before fastening the contact spring, the latter is already fixed to its carrier in the proper position so that accumulated tolerated tolerances are largely suppressed and a subsequent adjustment is avoided.

Title: Telecommunication network node
Inventor: VAN TETERING JOHANNES A M
IPC: H04J3/00
Filed: 1994-09-19
Abstract: Abstract of the disclosure:         A telecommunication network node is proposed which provides a novel solution to the realignment of payload of an input datastream (IN) within an output datastream (OUT) after dismantling the former.          The present network node thereto generates from the payload of the input datastream (IN) data units (MSCI) some of which include a time label (TL) indicative of the moment at which they are derived. These data units (MSCI) are stored in a buffer (BM) from which they are read at a varying rate determined to track the input datarate and constituting the output datarate. This tracking is achieved by using the time labels to calculate a node delay, i.e. the delay between the derivation and the reading of a data unit, and by changing the above rate as a function of this node delay in order to keep it within predetermined bounds.          A particular embodiment of the present network node allows to cross-connect Synchronous Digital Hierarchy or SDH datastreams using an Asynchronous Transfer Mode or ATM switch (MPSR).

IPC: F23M11/00
Filed: 1994-09-27
Abstract: A gas fired combustion apparatus includes a porous combustion surface disposed in a combustion chamber substantially sealed to prevent entry of secondary air and having a pressure relief means that operates to relieve or suppress pressure changes which may otherwise occur in the combustion chamber with commencement of the burner operation.  Thereafter a subatmospheric pressure is maintained in the combustion chamber by a natural or aspirated draft.  The subatmospheric pressure cooperates with an aspirating flow of fuel to the burner apparatus to provide an increased flow of primary combustion air which reduces the combustion temperature and the emission of pollutants.  Alternatively, the subatmospheric pressure may be used to achieve a given flow of primary combustion air with a reduced combustion surface area.          Water heater applications of the burner apparatus are illustrated.

Title: Process for Decoking Catalysts
Inventor: RAMACHANDRAN RAMAKRISHNAN
IPC: C10G11/18
Filed: 1995-08-03
Abstract: Coke deposits are removed from particulates by combustion in a regenerator by a process in which air is initially used as the oxidant. The combustion gas is subjected to a separation process to remove nitrogen therefrom, and the remaining carbon dioxide-enriched gas stream is recycled to the regenerator together whilesubstantially pure oxygen is introduced into the regenerator. As the level of carbon dioxide in the system increases, the amount of air being introduced into the regenerator is gradually reduced and, in compensation, the amount of oxygen flowing to the regenerator is gradually increased. Eventually, part or all of the air is replaced by oxygen and carbon dioxide recycle gas, and the level of oxygen and carbon dioxide are regulated to maintain the desired temperature in the regenerator.
