Abstract: Un procédé et appareil d'enduction d'une bande de papier ou de carton permettent d'empêcher le dépôt et le séchage de la pâte d'enduction sur les bords de la chambre d'enduction en laissant couler continuellement le long de l'obturateur de bords (2) un flux de pâte d'enduction provenant de la chambre d'enduction. Chaque obturateur de bords est disposé dans l'espace compris entre les parois antérieure et postérieure (3, 4) de l'appareil d'enduction et la partie supérieure (11) de chaque obturateur de bords correspond à la forme d'un coin placé entre l'élément d'essuyage (9) de l'appareil d'enduction et la bande (12) à enduire. La pâte d'enduction s'écoule dans des interstices (13, 14) situés entre les obturateurs de bords et l'élément d'essuyage et entre les obturateurs de bords et la bande, la largeur de ces interstices étant comprise entre 1 et 10 mm.

Abstract: L'appareil décrit est le premier à ouvrir les interstices de la région dentaire, c.à.d. les espaces subgingivaux, par suppression de l'adhérence capillaire. Cette ouverture de l'espace capillaire s'effectue à l'aide d'un capuchon d'aspiration élastique (1) par création d'un vide hermétique au-dessus de l'interstice, ce vide neutralisant les forces d'adhérence capillaires. Ce procédé sous vide permet donc l'accès aux interstices interdentaires, ce qui n'est pas possible avec des appareils classiques (dispositifs de rinçage et d'aspiration par canules). L'application intermittente du vide produit une action de pompage qui, à l'aide d'un rinçage également intermittent, permet un nettoyage optimal des espaces interdentaires jusqu'à la base de l'alvéole. On peut de la même manière introduire des médicaments dans la base de l'espace subgingival à l'aide de ce procédé sous vide.

Plusieurs cylindres (28) sont disposés entre les surfaces (24, 26) des voies de roulement, afin d'assurer la transmission du couple dans une première direction depuis la voie de roulement interne (21) jusqu'au tambour (16), pendant que les cylindres servent de support de palier antifriction dans la direction opposée. Un second embrayage unidirectionnel (22) est défini entre la partie interne inférieure du tambour (16) et l'arbre fixe (14), la partie externe de l'arbre définissant une surface de travail (30) d'embrayage de voie de roulement interne et la partie opposée interne du tambour définissant une surface de travail (32) d'embrayage de voie de roulement externe. Plusieurs cylindres (34) sont disposés entre ces surfaces et permettent un engagement par accouplement entre les surfaces (30, 32) dans une direction opposée à la direction de travail du premier embrayage (20), assurant ainsi une action de rétro-vérification pour les positions rotationnelles du treuil (10) pendant l'enroulement autour de ce dernier d'un câble de manoeuvre. Les embrayages unidirectionnels (20, 22) sont du type à cylindres à surfaces hyperboloïdales, leur engagement se produit dans une seule direction et ils effectuent un mouvement en roue libre de rotation antifriction dans la direction opposée.

Title: Steam generator for burning brown coal with different compositions
Inventor: DERKSEN RUDI
IPC: F23C9/00
Filed: 1989-01-27
Abstract: For burning lignite with ash of varying composition in the fluidised bed (6) of one and the same steam generator, one of the heating surfaces (12, 13), which are arranged in flue gas passes (2, 3) downstream of the fluidised bed (6), is connected by means of connecting lines (43, 44, 45) which can be isolated, either as an economiser or as a superheater, as desired. The connection as economiser is selected if, for setting a fuel-dependent, low bed temperature of preferably 730 to 760 degrees C in the fluidised bed (6), a predetermined flue gas rate is recycled via the recirculation line (29). The heating surface (12, 13) is connected as superheater if, for setting a fuel-dependent, higher bed temperature of preferably 820 to 850 degrees C in the fluidised bed (6), a lower flue gas rate is recycled.

Abstract: An electroless copper plating bath contains copper sulfate, EDTA, DMAB and triethanolamine and is adjust­ed to a pH in the range between approximately 8 and 9. The addition of cyanide ions alone or preferably with a sulfur compound such as thiodipropionic acid or a nitrogen compound such as 1,10 phenanthroline provides bright copper deposits. The use of an electroless plating bath operating at a low pH permits electroless plating of alkali sensitive substrates.

Abstract: A signal which is dependent solely on the disturbance variable is selected by means of a filter and fed to a disturbance detector. This disturbance detector simulates the steady and alternating component (sine component) of the selected signal, as well as a signal (cosine component) phase-leading by 90 DEG  with the latter signal. The correction signal required to exactly compensate for the disturbance variable is determined from the sine and cosine component of the periodic disturbance signal component by means of frequency-controlled function generators and a complex phasor calculation.

Abstract: Double-acting seal arrangement for sealing a machine part (1), which receives the sealing in an annular space (2), in relation to an axially and/or rotationally moving, oppositely directed surface (3), with a pressure difference occurring in a changing direction. The sealing is composed of two oppositely oriented sealing rings which each act in one pressure direction. The sealing rings used are those which comprise in each case a thin-walled, tubular sealing-ring part (7, 8), a supporting part (6) which supports the sealing-ring part at its end facing the higher-pressure side, a sealing edge (9, 10) close to the other end of the tubular sealing-ring part (7, 8), and a clamping ring (13, 14) made of elastic material which is in contact with the tubular sealing-ring part and bears, on the one hand, against a front face (4, 5) of the annular space (2) and, on the other hand, against a front face (18, 19) of the supporting ring (6). The sealing rings face each other with their pressure side. The arrangement is dimensioned such that the pressure-side clamping ring (13, 14) lifts off from the associated front face (4, 5) of the annular space (2) under the effect of differential pressure. The spaces enclosed by the sealing with the oppositely directed surface (3) on the one hand and with the bottom of the annular space on the other hand are connected to one another (bore 12). The invention furthermore relates to a sealing for this arrangement. <IMAGE>

Abstract: A primary multi-layer structural component having insulation properties and the method of producing same is disclosed. The structure is comprised of opposing spaced apart face sheets, a plurality of internal core sheets, the core sheets being spaced apart from each other and from the face sheets. Truss means extend internally across the structure, the truss means being connected to and supporting the opposing face sheets, and being integrally connected to and supporting the core sheets. Such structure is produced by forming a stack of metal sheets in contact with each other, including a pair of outer face sheets and a plurality of core sheets positioned between the face sheets, and providing a predetermined stop-off pattern by placing stop-off material in certain preselected areas between the contacting surfaces of adjacent face sheets and core sheets, and of adjacent core sheets. The stack of sheets is then subjected to diffusion bonding to cause bonding of adjacent sheets in areas other than the preselected areas containing stop-off material, and subjecting the diffusion bonded stack to superplastic forming to cause stretching of the core sheets in the unbonded areas containing stop-off material.

Abstract: A method of setting electronic circuits within an electronic device such as a radio telephone in which one or more parameters of the circuit are checked in turn. The resulting output from a parameter under check is compared with a desired standard and if necessary an adjusting data signal is supplied to the circuit to alter its output towards the desired standard and the output rechecked. Once the output matches the desired standard the adjusting data signal is stored by the circuit. This check is continued through all of the parameters to be checked in turn. The electronic circuit includes a variable component whose value depends on the stored data and program means are provided to control the operation of the circuit so that the variable component operates according to the data stored. The invention provides a method of calibrating radio telephone circuits quickly and automatically either during their initial set up or during service to ensure that they meet the required specifications.
