Title: Servo-control method for the operating frequency of a sonic horn
IPC: B06B1/06
Filed: 1988-08-26
Granted: 1993-10-06
Abstract: That frequency of the vibrating element for which the power absorbed by the sonic horn is a minimum, or for which its efficiency is optimal, is determined periodically. This frequency is compared with the previously noted frequency and the operating frequency of the sonic horn is modified by a preset amplitude step after a specified number of comparisons resulting in a frequency difference greater than a preset tolerance. <IMAGE>

Abstract: The plate-like tray is provided in the form of a thin plate, preferably a deep-drawn plastic film, having a multiplicity of small blanks, arranged in the shape of a matrix, for holding objects which have a reference surface of a predetermined dimension and a bearing side which connects thereto in an angular manner. In this case, the small blanks are used for holding objects having projections. The small blanks in this case have only two surfaces, namely the bearing surface and a supporting surface running at an angle thereto, the bearing surface enclosing an angle of 20 DEG  to 70 DEG , preferably 45 DEG , with the plane of the undeformed plate.

Abstract: A system for transmitting an n-level data signal (dk) at a given symbol rate 1/T comprises a data transmitter (1), a transmission channel (2) and a data receiver (3) with an equalizer (30) of the decision feedback type. By arranging this equalizer (30) for forming an estimate ( @k) of a virtual m-level data signal (ck) instead of the output signal (bk) of the data transmitter (1) error propagation in the equalizer (30) is considerably reduced without thereby appreciably adding to the implementation-complexity of the system.

Abstract: A radiographic machine in which the exposure is equalized as between different areas of the image plane so as to enhance high spatial frequency features of the image and suppress low spatial frequency features and achieve other benefits as well. A fan beam (12) which is wide enough to encompass the object (16) being imaged (18) is swept across the object and segments of that beam (23) are individually pulse width modulated at each of a number of sampling intervals during the sweep by monostable or bistable shutter pins (20) which either completely block or completely uncover the sectors which they control (22). An alternate embodiment adds beam width modulation as well, by making the shutter pins either completely block their sectors or uncover them only to the degree necessary for beam width modulation.

Abstract: Supports (23) coated with epithelial cells, for example endothelial cells, are exposed to a nutrient solution (7) in an apparatus, the flow of this nutrient solution being increased in the course of a number of days. As in natural blood circulations, pulsations are produced with a reversal of flow. By means of this quasi-physiological loading, the cells on the support (23) become "used" to the loads to which they are subjected after implantation into the arterial vessel system of a human being. Their adhesion to artificial supports (23) is decisively improved by the conditioning treatment. <IMAGE>

Abstract: In a sub-band coder having several filter stages, the  problem exists to keep disturbances, which are produced by data reduction or quantization noise in one sub-band, out of other sub-bands in which these disturbances do not originally occur. Such disturbances occur when the noise components are reflected. According to the invention, the filter stages are dimensioned in such a manner that their transition areas do not overlap at any point in the frequency band. The stop-band corner frequencies of the individual filter stages are preferably identical. The filters can be used in sub-band coders, preferably for data reduction in digital broadcast transmission.

Abstract: An apparatus for recording an electric signal (A) on a magnetic record carrier (1) comprises at least one pair of write heads (K1, K2) having a mechanically rigid coupling to each other and arranged on a head drum (40). The record carrier (1) is wrapped around the head drum through a wrapping angle  alpha . The pair of heads (K1, K2) writes pairs of tracks (T1, T2; T3, T4; ...) on the record carrier. The apparatus further comprises a signal separator (4) for dividing the electric signal into consecutive blocks, after which the signal blocks having odd sequence number (B1, B3, ...) are applied to a first output (5) and the signal blocks having even sequence number (B2, B4...) are applied to a second output (6). In a time-base-correction circuit (7) the signal blocks (A1, A2) are time expanded or compressed.  alpha  Differs from 180<o>. Signal blocks having odd sequence number are delayed in time relative to signal blocks having even sequence number (16). Subsequently, the signal blocks thus processed are recorded. Time compression or expansion is effected by a factor of  alpha n/180.(M+1), where n is the number of head pairs and M is the number of times within a specific time interval that a head pair which comes in contact with a record carrier during said time interval does not record a signal in the record carrier, which time interval is defined by those instants at which two consecutive track pairs are recorded by one or two head pairs. Moreover, an apparatus is described for reproducing the signal recorded by means of said recording apparatus.

Abstract: Un matériau élastique est utilisé comme couche de base de couches surjacentes d'une fibre optique enroulée sur une bobine. Dans une mode de réalisation, le critère de sélection de la couche de base est sa compatibilité avec un revêtement de la fibre optique. Dans un autre mode de réalisation, le matériau élastique (10) comprend un revêtement agencé sur la bobine. Dans un autre mode de réalisation, la couche de base comprend un matériau en silicium. L'utilisation d'un matériau élastique comme couche de base rend superflus la fabrication et le stockage d'un matériau coûteux pour cuches de base formé de fils métalliques. L'utilisation du matériau élastique doit également réduire les sollicitations de la première couche de fibre enroulée. En outre il est plus facile d'accorder les propriétés thermiques de la fibre optique avec les propriétés thermiques du matériau élastique (20) dans une large plage de températures que d'accorder les propriétés thermiques de la fibre optique avec le fil métallique qui forme la couche de base. Ainsi, on réduit la différence entre les caractéristiques de la dilatation thermique de la couche de base et de la fibre enroulée (25) dans une plage prévue de températures de fonctionnement, réduisant au maximum les risques de déroulement du paquet de fibres optiques sur la bobine pendant un stockage ou un dévidement prolongés.

Abstract: Un dispositif de transmission d'ordre comporte un organe de commande contrôlé (1, 10) qui introduit et achemine une instruction d'entrée (14) dans des systèmes de commande, notamment de machines, installations ou analogue. Un entraînement (3, 4), lequel peut être par exemple un système magnétique, imprime à l'organe de commande un mouvement oscillatoire (13) qui est détecté par le système de commande, notamment par un capteur (5, 6), lequel peut également être un système électromagnétique. Une instruction d'entrée (14) introduite dans l'organe de commande amène ce dernier à venir en contact avec une butée fixe (8), laquelle limite la mobilité de l'organe de commande. Ainsi aucun signal ou uniquement un très faible signal est introduit dans le capteur et par conséquent dans le système de commande. Le même effet est obtenu si la mobilité est réduite par inadvertance par des influences internes ou externes telles que la corrosion dans les points d'appui, la rupture de l'organe de commande, etc.
