Patent EP-0006980-A1 (EP)
Inventor: MURTIN FERNAND RAOUL CHARLES
IPC: G01N27/68
Filed: 1979-04-27
Abstract: Method of measuring the oxygen concentration in a gaseous mixture in particular of determining the oxygen percentage in the exhaust gases of an internal combustion or external combustion engine, and ionization probes for carrying out this method. For determining the oxygen percentage in the exhaust gases of an internal combustion or external combustion engine, an ionization probe (1) is disposed in the path of the gases. This probe is supplied in parallel with an identical probe (2) traversed by the ambient air raised to the same temperature as the exhaust gases. The sum (13) of the currents picked up by the two probes is compared (14) either with a voltage proportional to the high voltage (17 to 19), or with a constant voltage (16), or with a constant current (16a), and, as a function of the difference, the high voltage (7) supplying the probes is controlled. In addition, the currents picked up by the probes are compared (10) and the result of the comparison enables the oxygen percentage to be determined. <IMAGE>

Abstract: In the new method for preserving workpieces, such as e.g. containers, by applying a coating by a dipping process in which the respective workpiece is directly held during the passage through the dipping bath and made to rotate at least for a time, the procedure adopted is that, during its rotation about the axis of rotation, the workpiece is rotated with changing angular speed. The angle of exchange formed between the coating agent surface and the respective wall of the workpiece thus changes in a non-uniform fashion. In addition, the workpiece can also be adjusted about a transverse axis running essentially horizontally and vertically to the axis of rotation, in order to achieve an economical coating of points of the workpiece, such as e.g. recesses, undercuts etc., which are difficult to reach. A device for carrying out a method of this kind comprises a control unit (21) which is preprogrammed with the required operating parameters or collects these data during the coating process and correspondingly processes them. Furthermore, the respective gripping device or devices (13, 14) of the device holding the respective workpiece or workpieces can be arranged with cardanic mounting and adjustably in the vertical plane on brackets (9, 10) of the device in order to permit the adjustment of the workpiece about the aforesaid transverse axis. <IMAGE>

Abstract: in a pulsator device of the slide valve type for milking cows with each of the valves being operated by a pair of diaphragms driven by a vacuum applied from outside, the initial adjustment or gauging, after a certain period of working, is no longer present and it is not possible to correct the gauging at the place of working. 
     Furthermore, such pulsators cannot be used for milking ovine animals if they have not been suitably gauged at the works originally. 
     In order to prevent the device from getting out of tune and therefore changing the rate of operating and in order to make it possible to renew the gauging at the place of working and to alter it if it is desired to use the apparatus for ovines also, instead of expelling the air which happens to be present on the other side of the diaphragms, said air is made to move in a closed circuit through a pipe (31) which links the two chambers concerned (29 and 30) with the opening of the passage which is adjustable from outside.

Abstract: An infusion package, such as a tea bag, has a stable three-dimensional expanded configuration and a flattened configuration suitable for packing. Preferably, the bag (12) hat a generally tetrahedral shape whereby its internal volume is greater than that of prior bags of essentially similar height and width and whereby the tea leaf particles are less constrained during brewing. Although ordinarily such a shape would be inconvenient for packing purposes, folds (23, 24, 25) in the tea bag permit its collapse to a flattened configuration that can be packed in quantity. A string or plastic strip (13) can be affixed at or near a fold (24) so that, by pulling on the string or strip, the bag can be expanded to its stable, three-dimensional configuration.

Abstract: A circuit is provided for synchronizing a transmitting/receiving station to the data network of a digital communications system having a correlation receiver in the relevant receiving device which supplies a correlation signal serving for synchronization purposes. The function of the correlation receiver is to implement the bit synchronization and block synchronization for the most favorable radio range from an asynchronous state, in the synchronous state to supply the adjustment criteria for the current radio range and, in the event of rebooking, to supply those of all the other possible radio ranges (indirect access to the adjusting elements via a computer). For this purpose, in the receiving device, the incoming non-generated items of received data are fed, on the one hand, to the correlation receiver and, on the other hand, to a regenerating device which can be set up by the signals of the correlation receiver. The correlation receiver comprises a signal output for the received pulse train setting-up (bit synchronization) and a signal output for block synchronization. The two signal outputs are connected to a computer. In addition, the signal output for the bit synchronization is connected to the regenerating device via a computer-control switch and via a phase pulse train shift device, whereas the signal output for block synchronization is connected thereto via a switch which is also controlled by the computer.
