Title: Device for transferring a dry concrete mixture and similar building materials into a pneumatic spraying feed pipe and spraying device with such a transferring device
IPC: B65G53/32
Filed: 1988-01-16
Granted: 1992-07-15
Abstract: The device for transferring granular dry material into a pneumatic feedpipe (32), for example a concrete spraying machine, consists of a material-feeding hopper (4) having a blocking slide valve (6) which can be actuated by a pneumatic working cylinder (8). Arranged one behind the other underneath the blocking valve (6) are two tube sections (16 and 22) which are each subjected to the action of a tube-squeezing device (34 and 38 respectively), between which the tube sections (16 and 22) form a sluice chamber (44) which is additionally provided with a blowing-air connection (62). The blocking valve (6) and the upper tube-squeezing device (34) form a prechamber (42). When the upper tube-squeezing device (34) is closed and the blocking valve (6) is open, the prechamber (42) is filled by free fall from the feeding hopper (4). The sluice chamber (44) can at the same time be discharged into the pneumatic pipe (32) by opening the tube-squeezing device (38). The top (6) and bottom (38) blocking elements then close again and the contents of the prechamber (42) are discharged into the sluice chamber (44) by opening the upper tube-squeezing device (34). The tube-squeezing devices (34 and 38) work against an empty tube. The only blocking elements in contact with the material is the blocking valve (6). Otherwise, the device has no sealing parts which are subject to wear. <IMAGE>

Title: Circuit arrangement for the detection of oscillations
IPC: H04R3/02
Filed: 1988-02-04
Granted: 1991-10-30
Abstract: A circuit arrangement for suppressing oscillations, such as acoustic feedback in a hearing aid, has a circuit which recognizes the presence of oscillations in a useful signal, an oscillatory frequency search circuit, and an oscillation modifying circuit controlled by the search circuit. The oscillation modifying circuit suppresses oscillations by filtering. Drift effects are avoided by a frequency clamp-on sub-circuit in the search circuit, which retains the frequency of the recognized oscillation at the modifying circuit, even when the oscillatory signal at the input of the search circuit disappears.

Abstract: Dans un dispositif traditionnel absorbant les courants de choc, des plaques d'électrodes discoïdes (3a, 3b) sont soudées à la surface d'une électrode (2) d'un varistor (1) et des bornes externes (4a, 4b) partent des parties terminales. Dans le dispositif absorbeur de courants de chocs ci-décrit, par contre, l'électrode (6) d'un varistor (5) présente des surfaces sur lesquelles des plaques d'électrode (7a, 7b) sont soudées. Ces plaques comprennent des fentes (9) découpées essentiellement radialement et des bornes externes (8a, 8b) s'étendant essentiellement depuis le centre. Etant donné que dans le dispositif absorbeur de courants de choc ci-décrit les bornes externes (8a), (8b) s'étendent depuis le centre, les plaques d'électrode (7a), (7b) viennent en contact de manière uniforme avec l'électrode (6), ce qui permet d'effectuer un soudage de bonne qualité. Par la même occasion, la densité du courant à l'intérieur du varistor devient uniforme, ce qui permet d'obtenir une résistance suffisamment élevée aux courants de choc.

Abstract: Circuits, and methods of using the same, are disclosed for controlling the power supplied to a discharge lamp of the type having a closed inductive loop, such as the resonant ballast circuit for a fluorescent lamp or the inductive ballast loop of a high pressure sodium lamp, wherein the closed inductive loop is operated by an electrical power supply having a d-c input stage and an output power controlled by the switching of a switch means within the power supply itself whereby current flows to the closed inductive loop when the switch means is conductive and no current flows from the power supply to the closed loop when the switch means is non-conductive. The instantaneous current flowing through the switch means itself is sensed and integrated to provide a first signal having a value that is proportional to the actual power being supplied to the closed loop. An error signal is created having a value indicative of the difference between the first signal and a second signal with a value proportional to the desired set point power for the lamp. The switching of the switch means is adjusted in accordance with the value of the error signal, whereby the output power of the power supply is continuously adjusted toward the set point power for controlling the power actually supplied to the lamp circuit irrespective of the parameters of the lamp circuit itself. The disclosed circuits provide for constant power to a high pressure discharge lamp to yield a constant color temperature. Further, the disclosed circuits provide for dimming of the discharge lamp to selective power levels.

Abstract: L'invention concerne un procédé de suppression de l'ambiguité azimutale, c'est-à-dire l'ambiguité de doppler, dans un récepteur SAR à bord d'un aéronef en mouvement, par exemple un avion, ce qui permet d'avoir une fréquence de répétition à impulsion (PRF) plus basse, sans provoquer une ambiguité de portée. Des échos radar sont reçus à bord de l'avion à l'aide d'une antenne ayant des première et seconde ouvertures pour produire des premier et second signaux de retour correspondants. Le premier signal de retour est traité sur une période de temps donnée pour générer une première série de signaux composants SAR représentant les échos radar provenant de cellules respectives d'une grille azimut-portée. Le second signal de retour est traité sur la période de temps donnée pour générer une seconde série de signaux composants SAR représentant des échos radar provenant des cellules respectives de la grille azimut-portée. Les signaux composants, pondérés individuellement, sont combinés par addition pour produire une troisième série de signaux résultants SAR représentant les échos radar provenant des cellules respectives de la grille azimut-portée. La combinaison additive pondérée des signaux composants résout l'ambiguité azimutale, même si la PRF est inférieure à la PRF minimum prescrite généralement par la sagesse.
