Abstract: A valve seat arrangement sealing against a valve core (26) in a valve, particularly for a ball valve, having an inner ring (70) with a first deflectable sealing lip (80) and an outer ring (68) with a second deflectable sealing lip. The first deflectable lip is arranged to protrude forwardly to make initial contact with a closing valve core and once deflected, the second lip is arranged to land against said closing valve core forming a secondary seal. The first sealing lip and the second sealing lip are fashioned having selectively angled beveled surfaces facing the core. The invention provides an effective sealing arrangement for high temperature service.

Abstract: Disclosed is a hydrophobic porous membrane with a polymer having fluorinated alkyl side chains held in physical contact with the surface of a polyolefin porous membrane in which the fluorinated alkyl side chains of the polymer are crystallized, as well as its manufacturing process. Also disclosed is a hydrophobic porous membrane with a fluorinated crosslinked polymer from a fluorinated monomer with a fluorinated alkyl side chain and a crosslinking monomer held in physical contact with the surface of a polyolefin porous membrane, in which the fluorinated alkyl side chains of the fluorinated crosslinked polymer are crystallized, as well as its manufacturing process. These porous membranes use polyolefin porous membranes having a higher mechanical strength and lower costs than the fluorinated polymer porous membranes and still provide superior hydrophobicity over polytetrafluoroethylene type membranes.

Abstract: A voltage controlled oscillator runs at full speed to generate an output frequency dependent on temperature and process variation. First and second clock signals are generated from the oscillator signal (18), while third and fourth clock signals are developed in response to an input clock signal (20). The number of clock signals occurring during a first state of the third clock signal are counted for (24, 26) providing a plurality of output signals also indicative of the temperature and process variation. The plurality of output signals compensate an input signal for the temperature and process variation for providing an output signal (34).

Abstract: The position sensing apparatus comprises first (36, 38) and second (48, 50) magnetic field conducting means which are rotatable with respect to each other about an axis (8). Each includes a plurality of magnetically permeable members having respective surfaces extending transversely from each other by gaps. The shaped surfaces of the first magnetic field conducting means (36, 38) face the surfaces of the second magnetic field conducting means (48, 50) and are separated from each other by a gap (54). The shapes, positions and areas of these surfaces are chosen to tailor the magnetic coupling between the first and second field conducting means for a desired output waveform over a selected angular range of rotation. 
     Third magnetic field conducting means (40) is provided for magnetically coupling the magnetically permeable members of the first magnetic field conducting means (36, 38) though a sensor gap. Fourth magnetic field conducting means (52) is provided for directly magnetically coupling the magnetically permeable members of the second magnetic field conducting means (48, 50). A magnetic field producing means (44, 46) is also provided for effecting the production of a magnetic field having flux lines which pass through the first and second magnetic field conducting means in directions which are substantially parallel to the axis (8). Sensing means (8), such as a Hall cell, is disposed in the sensor gap for sensing the magnetic field magnitude in that gap. This magnitude represents the angular position of the first magnetic field conducting means relative to the other. The sensor (14) is in a direct flux path of a magnetic circuit formed by the various field conducting means and its electrical output is not significantly affected by extraneous magnetic fields of substantial magnitudes.

Abstract: A digital-to-analog converter comprises a sigma-delta modulator (4) for generating a 1-bit digital signal (D3) modulated synchronously with a clock signal (NF s ) in response to a digital input signal (D2), which modulator is followed by a asynchronous analog sigma-delta modulator (6) for generating a bivalent asynchronously modulated signal (D4) in response to the synchronously modulated digital signal (D3). The information in the digital signal (D3) from the sigma-delta modulator (4) resides in signal transitions which can appear exclusively at discrete instants defined by the clock signal (NF S ). The information in the asynchronously modulated signal (D4) from the asynchronous sigma-delta modulator is contained in an analog variation of the duty cycle. This means that the signal transitions of the asynchronously modulated signal (D4) are not tied to a fixed pattern of discrete instants but that all the intervening instants are also available. As a result of the freedom of the positions of the signal transitions the frequency spectrum of the asynchronously modulated signal (D4) has a substantially smaller width than the frequency spectrum of the synchronously modulated digital signal (D3) from the sigma-delta modulator (4). This enables the interface (16) with the further signal processing (8) to be simplified.

Abstract: A keypad scanner mechanism which may be incorporated with an integrated circuit including a microcontroller. The keypad scanner mechanism includes a keypad with more than one key. The keypad scanner mechanism has an activity detect mode and a normal mode. In the activity detect mode, the keypad scanner mechanism wakes up the integrated circuit and triggers the normal mode. In the normal mode, the keypad scanner mechanism identifies and reports to the microcontroller the depression of keys on the keypad. The keypad scanner mechanism also includes a means for debouncing, a multiple keys down code, and a no keys down code. The keypad scanner mechanism is suitable for any keypad application, however, it has been found that the keypad scanner mechanism is especially suitable for incorporation into the base and handset units of a cordless telephone that integrates the speech, control channels, and microcontroller portions of a modem, and the man-machine interface functions of a cordless telephone.

Abstract: On contrôle la circulation sanguine à travers un vaisseau sanguin au moyen d'une artériographie. On injecte dans le vaisseau sanguin un bolus de colorant opaque aux rayons X au moyen d'une seringue mécanique (16) pendant une période inférieure à un cycle cardiaque en réaction à la sortie d'un moniteur d'électrocardiogramme (14). On injecte le bolus colorant à un point prédéterminé du cycle cardiaque. Un dispositif de radiographie (10) crée ensuite une séquence d'images radiographiques, ledit dispositif incorporant un renforçateur d'images à des intervalles prédéterminés, de façon à fournir une indication du déplacement du bolus à travers le vaisseau sanguin et à travers ses ramifications. De préférence, la séquence d'images radiograhiques est convertie en format numérique, l'ensemble de valeurs numériques représentant chacune des images radiographiques étant soustrait au moyen d'un ordinateur (12) des valeurs représentant l'image radiographique suivante de la séquence. Toute valeur numérique négative est convertie en zéros numériques. Afin de fournir une indication sur l'écoulement volumique à l'intérieur du vaisseau sanguin, on calcule, pour chaque ensemble de valeurs numériques généré par la soustraction, la densité de colorant opaque aux rayons X à l'intérieur d'une zone fictive prédéterminée, dont au moins une partie recouvre la zone occupée par le vaisseau sanguin dans les images radiographiques. On peut ensuite utiliser les densités calculées afin d'évaluer l'écoulement volumique.

Abstract: A telecommunication device for the deaf is designed to operate under an enhanced TDD communication protocol. The TDD is capable of communicating with conventional TDDs operating under normal Baudot/Weitbrecht communications, but is also capable of communicating with a similarly enhanced TDD utilizing an enhanced protocol with a faster data transfer rate. The enhanced TDD is capable of signaling to another remote TDD through the use of a synchronization character that it is capable of enhanced TDD communications. If a similar synchronization character is received from the remote station, both TDDs can then switch to enhanced TDD communication with its advantages of speed and enlarged character set. The synchronization character is especially designed so as not to interfere with the operation of a conventional TDD which might receive the character and also to be sufficiently distinctive so as to be capable of definite reception by enhanced TDD machines with minimum error.
