Patent EP-0050345-A1 (EP)
Inventor: PINCKAERS HUBERT B
IPC: F23N5/24
Filed: 1981-10-17
Abstract: A fuel burner control system with an intermittent gas pilot is utilizing a flame signal simulating circuit to provide for both dynamic as well as static safe start checking of the system. By said simulating circuit a flame simulating signal is provided to a switching circuit (35) which causes pull in of a first relay (40). Said relay (40) is maintained in an energized state while a second relay (73) is conditioned to pull in. Conditioning is provided by a thermal time delay circuit (70, 74, 75) or by a further relay circuit. The first relay (40) is then allowed to momentarily drop out and a normal start up of the device then proceeds.

Abstract: The surface of a workpiece is coated with a metallic material by the use of a spraying device in which an electric potential is applied across two metallic wires (W1, W2) to establish an arc therebetween, the wires being progressively advanced towards the arc as they are melted by the arc. Gas under pressure is fed towards the arcing zone, the gas including a carrier stream to cause molten metal droplets produced by the arc to be carried away from the arcing zone towards the surface to be sprayed, and optionally one or more supplementary streams such as may be operative to constrain the carrier stream to a desired (e.g. conical) shape. In accordance with the invention, one or more of the streams of gas includes, or is provided by, a modifying agent, afforded by a substance or composition which is effective to modify the coating sprayed onto the workpiece, compared with the coating produced by the use solely of air. The modifying agent may produce a chemically or physically modifying effect in relation to the conditions pertaining at or in the vicinity of the arcing zone, and/or a chemically or physically modifying effect in relation to the coating sprayed onto the workpiece.

Abstract: Transcutaneous electrical nerve stimulation is applied to the patient, as though electrocardiograph monitoring is not being practiced. The EKG signals are preprocessed through a selective sample and hold module, which performs amplification, comparison with selective frequency and amplitude standards (as by differentiation) and temporary holding of EKG signals at such time as the transcutaneous nerve stimulating pulses are occurring, as sensed against the frequency and amplitude criteria. In the absence of transcutaneous stimulation signals, EKG signals are coupled directly through for conventional EKG processing.

IPC: F16C1/22

Abstract: In a cable-and-sleeve connector, variations in the real or effective length of the cable 3 will tend to vary the curvature of the sleeve 7, and this can be accommodated by variations in the effective length of the sleeve 7. For this purpose, one end of the sleeve 7 is adjustably fixed to an anchor 6 by a clutch 31. When the cable 3 is relaxed, the means by which the cable 3 can be tensioned moves a member 40 to disengage the clutch 31 so that the position of the end 36 of the sleeve 7 can vary axially within the clutch. Tensioning the cable 3 releases the member 40 to allow the clutch 31 to engage again, with the end of the sleeve 7 fixed relatively to the anchor 6 in whatever position to which it may have been moved by any change in the curvature in the sleeve 7.

Abstract: This invention relates to a method for manufacturing pebbles or balls of varying diameter, constituted by a mixture of powders having heat insulating and soundproofing characteristics, which are either mixed or not mixed with inert powders, are bonded together by cement and are subjected to centrifugal action, the invention also relating to a machine for carrying out said method. The conversion of powdery materials into pebbles leads to considerable advantages, namely economical advantages due mainly to the possibility of dispensing with packaging into bags, as is indispensable in the case of powdery products, transportation thus being able to be carried out with bulk material, and technical advantages, which consist mainly in the possibility of selecting the size distribution of the pebbles for use in concrete used for casttings in the building industry, which require insulation, lightness and strenght characteristics.

Abstract: Transistor bipolaire plat fabrique par implantation sequentielle a zone selective d'ions dans un materiau III-V, tel que du GaAs, pour former deux jonctions p-n (16, 21).

IPC: H04L25/49
Filed: 1982-03-31
Abstract: A device is described forthe interrogation and correction of a data signal which adopts a finite number of discrete signal values in a consecutive series of data cells. The transitions between the signal values exhibit a nominal minimum spacing. The signal is periodically interrogated with a period which amounts to at the most half of said minimum spacing. If a finite series of successive interrogation values exhibits a permissible pattern, the data value is directly derived therefrom (36). There is a set of further patterns which are not permissible, but which do not deviate excessively from a permissible pattern; the associated data value of the corresponding permissible pattern is then simulated. In the other cases an error signal (34) is formed. The patterm has a length which exceeds the length of a data cell. The inherent redundancy of the data signal is thus partly used for the correction of errors.

Abstract: Fibre optique ne permettant essentiellement qu'un mode unique de visage, éventuellement dégénéré, à la longueur d'onde de transmission, habituellement entre 06 et 1,7 microns. L'indice de réfraction du matériau du noyau est gradué dans la direction radiale de manière à obtenir une fibre optique avec une très faible dispersion totale et par conséquent une largeur de bande étendue. Des modes de réalisation spécifiques comprennent, en plus des caractéristiques de faible dispersion, une délimitation améliorée du champ, permettant d'obtenir ainsi des rapports revêtement/noyau inférieurs aux valeurs que l'on avait auparavant jugées utilisables dans la pratique. Des avantages supplémentaires résultant de la plus grande délimitation du champ comprennent de plus faibles pertes dues au câblage, aux micro-flexions et aux rayons de courbure.

Abstract: An electrical timing circuit for controlling the activation and deactivation of an electrical load by setting a predetermined time period for which the load will be on and for providing one or more short warning periods wherein the load is deactivated prior to the expiration of the predetermined time period. The invention may be used as a switch for a light whereby the light may be actuated to remain on for an hour, but just prior to the expiration of hour period the light will momentarily go off for one or more warning periods prior to the light being turned completely off so that the switch may be reactuated to start another timing period. Momentary switches (12) control a set-reset circuit (16) which sends a signal to a NAND gate (18). A timing circuit (20) is responsive to the momentary switches (12) to provide a plurality of time spaced-signals. A first gate means (22) responds to the timing circuit (20) to provide an input to the summing gate (18) to effectively turn the load off, but only for short warning periods. A second gate means (24) is responsive to both the first gate means (22) and the timing circuit (20) to provide an input to the set-reset circuit (16) to effectively turn the load off at the end of the predetermined period.
