Abstract: Screw conveyors with a slowly rotating conveying screw (2) for the fine metering of very small quantities convey the same amount of material with each rotation of the screw. In the relatively short periods of time of a single rotation, which depending on requirements may however have a duration of one min or a multiple thereof, the output fluctuates since the individual turns of the conveying screw always bound discrete quantities of the material being conveyed. So as to make it possible to use a screw conveyor also for the fine metering of extremely small quantities, that is to say for extremely small outputs with high constancy, i.e. without the periodicity due to the nature of the conveying screw, of the material discharge, said conveyor is provided with a rotatably mounted tube (5) which surrounds the outlet end (3b) of the fixed conveying tube (3) and is driven at a speed of rotation which is proportional to the speed of rotation of the screw (2).

Abstract: Un instrument de diagnostic ophtalmique (10) détermine la forme de la cornée (24) par projection d'une image sur la cornée (24), à travers l'optique de l'instrument de diagnostic. L'instrument et le procédé de l'invention consistent à plier une configuration projetée de sources de lumière ponctuelle, séparée, discrète, de sorte que la configuration est projetée vers l'oeil, coaxialement avec de la lumière collectée en retour, reflétée par la cornée. L'instrument (10) évite de recourir à une source de lumière de configuration directement adjacente à l'oeil, et fournit au chirurgien ou à un autre spécialiste des soins oculaires une image en temps réel représentant avec précision la forme de la cornée. Ainsi, le chirurgien est en mesure de contrôler la forme de la cornée avant d'effectuer une intervention chirurgicale, il peut contrôler ses changements se produisant au cours de l'intervention chirurgicale, et il peut également contrôler la cornée dans des phases post-opératoires. Selon un mode de réalisation spécifique de l'invention, une image réelle (22) de la configuration des sources de lumière ponctuelle, est formée à l'intérieur, à proximité immédiate et devant la lentille de l'objectif (20) du système, de sorte que la lentille de l'objectif devient une lentille de champ, et l'angle visuel du système est élargi.

Abstract: A multi-bolt door lock possesses a mortise lock case (2) provided with key and handle actuation and having a lock bolt (5) laterally extendable from this and a further espagnolette bolt (6) which can be extended upwards out of the door leaf (1) and is under the effect of a spring (10) and which is to be retracted as a result of the actuation of the handle follower (17) and detained in its retracted position by a shift latch (11) which, in the closing position of the leaf, is to be disengaged by striking against the fixed door frame (7) and thereby releases the espagnolette bolt (6) for its extension movement. In order to bring about especially deep locking engagements in the closing position of the door leaf with comparatively little effort from outside, especially also simply by actuating an outer key, and prevent the possibility of maloperations of the shift latch, the lock bolt (5) and the espagnolette bolt (6) are connected to one another in drive terms and are to be adjusted jointly with a comparatively large stroke by inner-handle and outer-key actuation, the shift latch (11) being arranged on the leaf top edge in the exit region of the espagnolette bolt (6).

Abstract: In an electrically operated household food processor for processing and preparing foodstuffs of all types, an electric motor (8) is arranged in a housing (1), which electric motor (8) causes an operating tool, which is located in an operating container, to rotate in order to manipulate the foodstuffs. The electric motor (8) is supplied with cooling air via a fan impeller (38) which is driven by a motor and is arranged in the housing (1) such that it can rotate, the electric motor (8) on the fan impeller (38) being arranged in an air duct (4) which forms an air inlet (45) at its one end and an air outlet (46) at its other end. In order to achieve a construction of the household food processor which is as compact as possible with a motor power which is nevertheless high, and at the same time in order to reduce the motor noise, the fan impeller (38) is driven by a further electrically operated fan motor (30), which is constructed separately from the electric motor (8) in the housing (1), and has a fan impeller (38), and which does not switch on the fan motor (30) until a selectable power consumption of the electric motor (8) is exceeded.

The associated agitator shaft (22) has an inner shaft end (38) arranged in the milling space (18) and contains a cavity (40) which is open at the end side of the inner shaft end (38) so that milling bodies (50) and material (52) for milling can flow into it at the end. The agitator shaft (22) has outlet openings (46) round the cavity (40), said openings allowing milling bodies (50) which have passed through the inner shaft end (38) into the cavity (40) to flow back into the milling space (18). In a central region of the cavity (40), a separating device (42) is arranged which allows finished ground material (52) to flow out of the milling space (18) to the outlet (30) for milled material, but retains milling bodies (50). The cavity (40) is divided inside the agitator shaft (22) into an inner zone (70) and an outer zone (72) by means of an intermediate cage (60) which is arranged on the same axis as the separating device (42) all around the latter and is driven in rotation. Between the inner shaft end (38) and the separating device (42) a deflector (54) is arranged which prevents milling bodies (50) and material (52) for milling flowing axially directly into the inner zone (70). <IMAGE>

Abstract: Relative piston misalignments between segments of a multisegment optical system, such as a segmented primary mirror (2), are reduced by a method in which elements of an arbitrary unknown extended scene image carried by an input beam (4) are eliminated from the beam's error information in performing an error calculation. After appropriately processing the beam (4) with the specialized sensor elements (9), spatial frequency domain representations of a variety of optical images are obtained which correspond to both individual segments, and to multiple combinations of segments of the optical system; each combination is preferably composed of two individual segments. The spatial frequency domain representations of the individual segments are then subtracted from the representations of the segment combinations to obtain spatial frequency domain functions for the combinations. These in turn are compared by a cross-coherence technique to derive spatial domain differences of piston differences misalignments between the combinations, from which the piston errors between individual segments can be calculated via a reconstruction matrix. The calculated piston errors are then used to make a compensating adjustment (8) to the piston positions of the individual segements in the optical processing element.
