Patent EP-0002855-A1 (EP)
Inventor: DILOT ROLF MAGNUS
IPC: B65B5/08

Abstract: An arrangement for the feeding of objects to and grouping them on a base. 
     In order to simplify handling and transport of milk packages it is frequent to use transport packages in the form of trays (3) or the like, onto which a number of milk packages (16) are placed in close stacking. For this purpose automatic machinery is used, which machinery automatically loads the milk packages on a transport package placed in position for loading. In order to avoid interruptions when an empty transport package has to be substituted for a filled one this invention suggests an arrangement according to which the milk packages are first collected in close stacking on a pre-loading surface (19). Thereafter, when the new transport package has been brought in correct position adjacent to the pre-loading surface, the collected milk packages are transferred onto the transport package.

Abstract: A milling machine for milling a face of a metal wprk- piece (34) has a cutter positioned to act on the face of a workpiece (34) passed through the machine. A control means is employed to ensure that the depth of cut on the face remains at its preset value regardless of variations in thickness of the workpiece (34) entering the machine. 
     In a preferred arrangement, the machine has a pair of cutters (2,4) positioned to act on opposed faces of the workpiece (34). The control means then ensures that the depth of cut on each face remains its preset value.

Abstract: The (R,R) optical isomer of labetalol, namely 5-[ (R)-1-hydroxy- 2-[(R)-1-methyl- 3-phenylpropyl)amino ]ethyl] salicylamide, and its pharmaceutically acceptable acid addition salts, in a state substantially free of the corresponding (R,S), (S,R) and (S,S) optical isomers, are novel compounds with favourable therapeutic properties in comparison with labetalol. They can be used in particular in the treatment of hypertension. 
     The novel (R,R) optical isomer and its pharmaceutically acceptable acid addition salts can be prepared by removal of the protecting groups from an N,O-protected (R,R) optical isomer or acid addition salt thereof, wherein the basic nitrogen atom and the phenolic hydroxy group are protected, preferably by hydrogenolytic removal of hydrogenolysable groups.

Abstract: Filtering devices wherein solid particulate matter is separated by filter media (40,46) from a liquid flow often contain conveying means (50) for moving the separated solid particulate to an external point for disposition. One such conveying means usable in filtering devices includes spaced endless (52,54) chain loops wherein each chain comprises alternate center links (62) pivotally joined by pins (66) to alternate sets of spaced side bars. In each center link is an elongated aperture (90) which in a controlled manner holds an extension bar (84,86) attached to each end of a traversely positioned flight (76). The spaced chain may be operatively connected to a source of rotary power (60) to periodically advance the conveying means so that the flights may be moved over a section of the filter media to effectively remove separated particulate matter collected thereon.

Title: Verfahren zur Umwandlung von linear codierten digitalen Signalen in nicht linear codierte digitale Signale gemäss einer dem A-Gesetz oder dem My-Gesetz gehorchenden Mehrfachsegmentkennlinie

Abstract: Bei einer Analog-Digital-Wandlung wird entsprechend einer logarithmischen Kompandierungskennlinie, die entweder dem sogenannten A-Gesetz oder dem sogenannten µ-Gesetz gehorcht, eine nichtlineare Codedarstellung erreicht, so daß das Verhältnis von Nutzamplitude zu durch die Quantisierung des Analog-Signals bedingter Störamplitude über den gesamten Amplitudenbereich konstant ist. Es kann hierbei so vorgegangen werden, daß die Digital-Signale zunächst durch einen linearen Code dargestellt werden und dann mit Hilfe eines einzigen Speichers, in dem die Zuordnung der Werte des linearen Codes zu Werten eines nichtlinearen Codes gespeichert sind, eine Umwandlung von linearere Codedarstellung in nichtlineare Codedarstellung vorgenommen wird. Je nachdem, welche der Kennlinien zugrund gelegt wird, ist hierzu bei Verwendung eines einzigen Speichers Speicherplatz für 64 kBit bzw- 128 kBit erforderlich. Aufgabe der vorliegenden Erfindung ist es daher, ein Umwandlungsverfahren anzugeben, das mit geringerem Speicherplatzaufwand auskommt. Erfindungsgemäß wird dies mit Hilfe von zwei Speichern (K1, K2) erreicht, von denen der erste (K1) nur mit einem höherwertigen Teil (2¹² bis 2<5>)der linear codierten Signal (SDL) angesteuert wird und aufgrund dieser Ansteuerung die höherwertigen Bits (2<6> bis 2<4>) des entsprechenden nichtlinear codierten Signalwertes (SDK) zur Angabe des gewünschten Segmentes der Kennlinie sowie eine höherwertige Teiladresse für den zweiten Speicher (K2) liefert. Dem niedrigerwertigen Teil der Ansteueradressen des zweiten Speichers (K2) sind die verbleibenden Bits (2<4> bis 2¹) der linear codierten Signalwerte (SDL) zugeordnet. Der zweite Speicher (K2) liefert aufgrund seiner Ansteuerung die Stufenwerte 2° bis 2³, die die entsprechenden Stufen des jeweiligen Segments der Kompandierungskennlinie kennzeichnen. Das höchstwertige Bit (V) der linear codierten Signale (SDL) stellt zugleich das höchstwertige Bit der nichtlinear codierten Signale (SDK) dar. Das niedrigstwertige Bit 2° der linearcodierten Signale (SDL) wird hierbei vernachlässigt.

Abstract: Un systeme de reproduction de sons possede des haut-parleurs droit et gauche, (S(R) et S(L)), respectivement, qui produisent des sons stereo droits et gauches, respectivement (Fig. 3). Un signal stereo droit, non seulement commande le haut-parleur droit (S(R)), mais est egalement inverse (B(RL)) et temporise (b1(RL) a b4(RL)) pour produire un signal de compensation qui est transmis au haut-parleur gauche (S(L)) pour produire un motif de sons de compensation temporises a partir du haut-parleur gauche. Le signal pour le haut-parleur gauche (S(L)) est inverse (B(LR)) et temporise (b1(LR) a b4(LR)) de maniere a produire un modele ou motif sonore de compensation a partir du haut-parleur droit. Les sons de compensation annulent sensiblement les sons stereo principaux (R1 et Lr) arrivant a l'oreille d'une personne (Re et Le) qui se trouve eloignee du haut-parleur pour produire un effet de relief ou certains des sons semblent se trouver a l'exterieur de la region du haut-parleur. Dans un second mode de realisation, les signaux stereo principaux et les signaux de compensation sont utilises pour produire un enregistrement (Fig. 10) qui a son tour produit les sons stereo principaux et les sons de compensation pour produire un effet de relief.

Abstract: Arrangement for modulating the output signal of a converter converting electric signals into other signals, for example optical signals. An analog signal is applied to a difference producer (6) the output signal of which controls a limiter (7). The binary output signal thereof controls the semiconductor laser diode (1) which is coupled to a photo-sensitive detector (3) for producing a feedback signal. After having been amplified in a broadband amplifier (9) and integrated in an integrator (13), this feedback signal is applied to the difference producer (6), in which the feedback signal is substracted from the analog signal. Variations in the optical output signal due to a non-linear conversion characteristic of the laser diode (1) and due to an optical retroaction of the fibre (2) on the laser diode (1) as well as output noise and signal-dependent amplitude variations are reduced by the negative feedback.
