Patent DE-4337922-A1 (DE)
Title: Joint prosthesis
Inventor: MAI STEFFEN DIPL ING
IPC: A61F2/00
Filed: 1993-11-06
Abstract: The invention is based on the object of specifying a finger joint prosthesis which permits considerable restoration of the natural joint mechanical functions, in which the joint permits a limited rotary movement about several axes and a limited movement in the longitudinal direction of the fingers despite connection of the two prosthetic joint members to the medullary space of the finger bones, and which permits treatment of several joints by coupling-on of further prosthetic components. This object is achieved in that the anchorage stems for a metacarpophalangeal prosthesis are designed as profiled medullary pins, in that a spherical cap-shaped rider and, centrically relative thereto, a partially spherical member are fastened to a medullary pin, and in that an inclined hemispherical member is fastened to the other medullary pin, which member has a slot and a spherical cavity. The invention relates to a joint prosthesis, preferably for a finger joint, which comprises a pivot joint and two anchorage stems. It is intended to restore the function of the hand and is particularly suitable for use in typical rheumatoid disorders of the hands. <IMAGE>

Patent DE-4405783-A1 (DE)
Title: Cylindrical rotor
Inventor: MORITZHUBER HELMUT
IPC: B27L11/00
Filed: 1994-02-23
Abstract: The cylindrical rotor has disintegrating elements (5), arranged distributed over the surface, for a device for disintegrating waste products, in particular for chopping up wood. The disintegrating elements (5) have a breaking/cutting edge which is closed at the circumference. They are releasably connected to the rotor (4) in each case by an attachment screw (15) which is disposed at right angles to the plane containing the breaking/cutting edge which is closed at the circumference. Recessed into the surface of the rotor (4) are locally bounded bores (12) of the blind bore type which are closed at the circumference and in which the disintegrating elements (5), designed as a truncated cone or pyramid, are inserted and screwed tight. The tapered base lies in the bore (12) which is designed to correspond to the truncated cone or pyramid. The axis of the attachment screw (15) encloses an acute angle  alpha  of approximately 10 DEG  with a diameter plane of the rotor (4) which runs through the imaginary intersection (17) of the axis (18) of the attachment screw (15) with the circumferential contour (19) of the rotor (4) (Figure 2). <IMAGE>
Patent DE-4412607-A1 (DE)
Title: Articulation
Inventor: SCHNELL BURKHARD K
IPC: E05D7/086
Filed: 1994-04-13
Abstract: Known articulations for apparatus flaps or furniture hinges are supplemented by further devices such as stops between flap and load-bearing structure, braking-type flap holders, weight compensation, etc. at various points of the flap. In this arrangement, the use functions of the flap can be obstructed, mounting is complex and the production costs for small production numbers are too high. The aim is to combine all the necessary functions in the articulation in largely pre-mountable manner and to permit simple attachment of the articulation on to the load-bearing structure, on the one hand, and of the flap on to the articulation, on the other hand. This is achieved by an articulation in the case of which the two main parts are a housing and a lever which is mounted rotatably thereon. Fixed stops for the two end positions, e.g. of a flap, are accommodated in the housing. Due to the suitable shaping of the lever head and the arrangement of leaf springs, the lever can latch into its end positions. Restoring springs and/or dampers produce compensating counter-moments on the lever. The interface comprising a pivot pin and a slave pin, with a flap, which exhibits merely one groove on its sides, permits the flap to be mounted on the articulation by simple plugging-in. The articulation is used, in particular, for stable door and flap fastenings in the construction of furniture or apparatus, where, at the same time, additional devices for the interaction of flap or door with the load-bearing structure are obstructive.

Title: Spring clip for securing removable parts to bolts or shafts
Inventor: KLEINHERNE PAUL
IPC: F16B39/04
Filed: 1994-05-05
Abstract: The spring clip (1) has a shaft (2) passing through a hole in a bolt (5). An at least doubly wound loop (3) exerts a force from its spring action upon deformation via the curved section (6) pressing on and passing around outside of the bolt.The stiffness of the multiple loop in the wire is less than that for a single loop occupying the same plan area. The desirable small force required to deform the clip for installation and ensure it remains in place is obtained from a small loop radius compatible with wire thickness.

Title: Method and device for decreasing the flow resistance on wings particularly aerofoils,and blades of turbomachines exposed to gaz flux such as air
Inventor: SPRANGER GUENTHER
IPC: F04D29/38
Filed: 1982-02-10
Abstract: The flow gaz is compressed before reaching the leading edge of the wing and expanded on the back of the wing. Simultaneously, gaz from the undersurface sucked by the expanded gaz is mixed therewith thereby increasing the flow on the back of the wing and directing it so that the flow speed of the gaz leaving the trailing edge is evenly distributed over the length of the wing, that the take off point migrates towards the trailing edge and that, in the direction of the wing edge, the gaz pressure on the back of the wing is increased. The back of the wing is provided, at the vicinity of its edge (4), with at least one or a plurality of flow throats (1, 1a) which are integrated, at the foot (5) of the wing (2), in its profile, and which are evenly warped along its length. The distance between the wing and the throats (1, 1a) increases, towards the wing end, up to a slot (6, 6a) of maximum width. The profile (8) of the throat (1, 1a) has a maximum curvature at the foot (5) of the wing (2) and is flattened at its free end (9). The subtended angle between the profile chord of each throat and the profile chord of the wing varies from the feet (12) of the throats (1, 1a) up to the ends (9, 9a) as a function of the variable curvatures along the throats (1, 1a).

Title: Method and apparatus for separating organic substances from a suspension or a solution
Inventor: REED THOMAS A
IPC: C12N5/071
Filed: 1983-01-13
Abstract: Method and apparatus for separating cells, organellae or proteins of a suspension or solution utilizing fixing bodies having a diameter of the order of 100  mu m provided with specific absorption surfaces. In order to maintain the fixing bodies (36) at a certain distance from each other, forming an open arrangement opposing the least possible resistance to flow, the fixing bodies (36) are ferromagnetic and kept in place or into magnetic field gradients in the reaction space (34) inside the reaction container (12) wherein the suspension flows (flow arrows C). Such result is obtained by two substantially different ways; either by a static arrangement wherein the fixing bodies are retained by magnetic fields on a surface, or by a dynamic arrangement wherein the fixing bodies move freely in a determined space wherein they are maintained by means of focused magnetic fields. A possible embodiment of the static arrangement comprises a thin ferromagnetic wire (38) arranged in an homogenous magnetic field (H0) inside the reaction space (34), the fixing bodies (36) adhering magnetically to said wire (38). In a possible embodiment of the dynamic arrangement, the reaction container is provided in a cylindrical coil, and magnetic field gradients at each end of the coil prevent the ferromagnetic fixing bodies to escape from the space defined by the coil.

Filed: 1985-07-25
Abstract: Ce procédé permet la mesure et/ou le réglage des caractéristiques de marche d'un moteur à combustion, telles que le contenu du noir de carbone, le nombre de tours du moteur, le commencement de l'injection et le recyclage des gaz d'échappement. Le procédé utilise l'ionisation des gaz à hautes températures et on mesure la conductibilité électrique des gaz ionisés contenus dans la chambre de combustion du moteur en détectant le composant avec le plus bas potentiel d'ionisation; on évalue ensuite les signaux électriques mesurés pour établir les caractéristiques de marche du moteur. Cela se rapporte de préférence à un moteur diesel, avec lequel le contenu du noir de carbone est le composant avec le potentiel d'ionisation le plus bas. Un détecteur se compose d'une bougie céramique de préchauffage qui présente, sur sa calotte située dans la chambre de combustion, une couche électrique conductrice et qui a fonction d'électrode, tandis que les parois de ladite chambre ont fonction de deuxième électrode. Le contenu du noir de carbone est directement mesurable après intégration des signaux et étalonnage, tandis que de l'intervalle entre les signaux de mesure, on obtient le nombre de tours. Le procédé peut être utilisé pour contrôler l'avance de l'injection, de même que pour régler le recyclage des gaz d'échappement.

Abstract: L'invention concerne un système de protection pour un moteur à combustion interne suralimenté. En régime normal, la suralimentation est commandée et/ou régulée à une valeur théorique (P théorique.) prédéfinissable. En cas de surcharge du moteur à combustion interne, plusieurs mesures de protection sont prévues qui entrent en jeu en fonction de l'importance de la suralimentation. Selon une première mesure de protection la commande et/ou la régulation de la suralimentation est coupée et un organe de réglage agissant sur la suralimentation est mis dans une position prédéfinissable. Selon une seconde mesure de protection, la distribution de carburant aux cylindres individuels est interrompue d'après un modèle de coupure prédéfini. Si ces mesures ne permettent pas de parvenir à une réduction suffisante de la suralimentation, il est prévu de passer successivement à d'autres modes de coupure présentant une fréquence de coupure plus élevée.
