Title: Pectins as foam stabilizers for beverages having a foam head
Inventor: WUBBEN MARIA ANNA
IPC: C12C11/11
Filed: 1995-08-03
Abstract: The invention provides pectins as new foam stabilizers for (temporary) foam heads in beverages, in particular in beers, especially beers of the pilsner type. These foam stabilizers are preferably obtained from hops, which is a constituent that is inherent in beer and accordingly offers the advantage, among others, that the foam stabilizers need to have no negative effect on the taste of the beer. Preferably, the pectins are obtained from hop cones or bines. It may be advantageous to partially saponify (de-esterify) the pectins, in connection with the number of charged groups on the pectins. In addition, the invention provides methods for obtaining the pectins and beverages stabilized with the pectins according to the invention.

Inventor: WOLF TORSTEN
IPC: G07D7/02
Filed: 1996-03-29
Abstract: L'invention concerne un procédé et des dispositifs permettant de vérifier des documents de sécurité. Selon le procédé de vérification de documents de sécurité, qui fait appel au couplage capacitif connu en soi, il est prévu que des signaux électriques émanant d'antennes émettrices soient transmis à des antennes réceptrices par le biais de caractéristiques de sécurité électroconductrices, et amplifiés. Ces signaux sont ensuite évalués d'après leur réponse d'amplitude et leur réponse en temps, et comparés à des courbes de signaux existantes, par conversion en courbes de signaux présentant des paramètres facilement comparables. Afin de parvenir à une sélectivité spécifique du dispositif de vérification, un amplificateur sélectif est en outre couplé à l'unité électronique d'évaluation. On parvient à une définition propre à la monnaie à l'aide de l'unité électronique d'évaluation, du fait qu'une limite de temps de l'amplitude du signal de vérification différant de la durée de la réponse d'amplitude de toutes les autres monnaies, peut être déterminée par exemple à l'aide de contrôleurs.

Abstract: A control system (10) and method for the operation of neurosurgical bipolar electrodes (11) provides a source of high frequency energy (13') connected to bipolar electrodes (11). Contacting surfaces are on the bipolar electrodes (11) of highly electrically conductive material. A current transducer attached to the source of high frequency energy (13') measures (20) the RMS current applied between the contact surfaces (25). A current transducer attached to the source of high frequency energy (13') provides a signal (26) correlated to the instantaneous values of the RMS voltage between the contacts. A control connects to the source of high frequency energy (13') for initially regulating the RMS current applied by the contacting surfaces in response to the impedance until the signal (19) divided by the measure (20) which is representative of the instantaneous impedance of the load reaches a predetermined value. The control regulates the RMS power applied by the contacting surfaces in accord with the impedance until the signal (19) divided by the measure (20) reaches a predefined value. The control responds to the measure (20) and the signal (19) so that the RMS voltage applied to the load being treated between the contacting surfaces regulated while its impedance is monitored until a prescribed value is reached. The control regulates the RMS  voltage applied in accord with the impedance by changing the RMS voltage to a percentage of that applied until the prescribed value is obtained so that the tissues stay moist and are coagulated without drying and carbonizing or turning to eschar.

Title: Dual seal coupling apparatus for enabling quick measurement of brake cylinder pressure
Inventor: SCOTT DANIEL G
IPC: B60T17/22
Filed: 1998-01-16
Abstract: A dual seal coupling apparatus enables quick measurement of brake cylinder pressure  through a  receiver  assembly of  a control valve.  The receiver assembly has a receiver body, a check valve housed in the body and a cover whose removal renders  the  check valve  accessible.   The  check valve  is normally compressed against a check valve seat to provide a first seal that prevents leakage of the pressure.  When moved away from its seat,  the check valve provides access to the pressure.  The apparatus includes a boss that protrudes from the cover and a male portion of a quick connect coupling.  The boss defines a threaded bore aligned with the check valve when the cover is secured to the receiver body.  The male portion includes a valve body and a valve stem.  The valve body defines a valve bore and has a threaded end for screwing into the threaded bore of the cover.  At its opposite end, the valve body is shaped to mate with a female portion of the quick connect coupling.  The valve stem moves within the bores and its head is normally compressed against a valve stem seat.  The head of the valve stem against the valve stem seat provides a second seal that further prevents leakage of the pressure.          When the male and female portions are mated, the valve stem is moved away from its seat thereby moving the check valve away from its seat and providing access to and enabling measurement of the brake cylinder pressure.
