Title: Fast packet switch
Inventor: TURNER JONATHAN SHIELDS
IPC: H04L12/56
Filed: 1983-01-12
Abstract: A communication method and packet switching system in which packets comprising logical addresses and voice/data information are communicated through the system by packet switching network (116) which are interconnected by high-speed digital trunks (118) with each of the latter being directly terminated on both ends by trunk collectors (131, 140). During initial call setup of a particular call, central processors (115) associated with each network (116) in the desired route store the necessary logical to physical address information in the controllers which perform all logical to physical address translations on packets of the call. Each network comprises stages of switching nodes which are responsive to the physical address associated with a packet by a controller to communicate this packet to a designated subsequent node. The nodes provide for variable packet buffering, packet address rotation techniques, and intranode and internode signaling protocols. Each packet has a field which is automatically updated by the controllers for accumulating the total time delay incurred by the packet in progressing through the networks. Each processor has the capability of doing fault detection and isolation on the associated network, trunks, and controllers by the transmission of a single test packet. The testing is done solely in response to the test packet and no preconditioning of controllers or networks is necessary.

Inventor: SATZLER RONALD LEE
IPC: B29C48/21
Filed: 1983-08-17
Abstract: An apparatus and method for continuously extruding an elastomeric hose (10) having a controlled internal size. A controlled internal size is necessary in order to mount various types of couplings to the hose. Other hose making processes require extruding the hose on a mandrel in order to control the internal size. The use of mandrels restricts hose length and requires additional floor space due to the lengthy mandrels. An extruded hose (10) having a controlled internal size is continuously made by extruding an elastomeric material over a first end portion (104) of an internal shaping member (102) and continuously monitoring the flow of air between a gauge member (112) and the internal size of the hose (10). The rate of extrusion is controlled in response to the flow of air between the gauge member (112) and the internal size of the hose (10) changing from a predetermined range. The continuous monitoring of the internal size adjacent the internal shaping member and adjusting the rate of extrusion in response thereto produces a continuous hose with a controlled internal size without the use of long mandrels.

Title: Circuit for effecting improved slew rate of operational amplifiers
Inventor: LEWYN LANNY L
IPC: H03F1/08
Filed: 1984-04-06
Abstract: An improved output circuit (109') for an operational amplifier which is controlled to operate in one or two modes. In the first mode, the output of the operational amplifier tracks a reference signal or ground. In the second mode, the output of the operational amplifier tracks the level of a time varying second voltage signal. The improvement consists of replacing the stabilization capacitor of prior art output circuits (109) with a pair of stabilization capacitors (123 and 125) connected in parallel. Each of the pair of capacitors has an associated series connected switch (127 and 129) for switching the capacitor into and out of the circuit. The switches are operated by a respective one of a pair of external non-overlapping clock pulse trains (PHI1 and phi2) so as not to be closed simultaneously. The effect of this improved output circuit (109') is to allow the output voltage of the operational amplifier to slew rapidly (or snap) up to the last previous level of a sampled input voltage (or a predetermined second reference voltage) thereby minimizing the effects imposed by the limiting of the first stage slew rate. Thus, slewing begins at a higher rate, governed primarily by the higher slew rate capability of the output stage, and consumes less time. In addition, the output voltage will snap directly from the level of the sampled time varying second voltage to the reference voltage level at the same high slew rate of the output stage. Because the voltage difference through which the stabilization capacitor must charge is greatly reduced, the output is able to reach and track the time varying voltage more rapidly than can prior art devices. The output of the operational amplifier thus shows greater correlation with the level of the second or time varying signal.

Abstract: Un connecteur de fibres optiques permet de produire des connexions de fibres de mode unique à très faible perte. Le connecteur utilise deux cylindres capillaires de verre étiré (31) pour tenir les extrémités (30) des fibres et plusieurs (de préférence trois) tiges cylindriques d'alignement (10) qui assurent un support multipoint des cylindres. Au moins une, de préférence deux, des tiges d'alignement portent un "plat" (13) s'étendant à partir d'une extrémité de la tige sur une fraction substantielle de la longueur de la tige. Le tout est assemblé grâce à des moyens appropriés, p.ex. un élément de fixation et alignement sensiblement triangulaire. La présence des tiges d'alignement portant des plats antiparallèles permet un alignement simple des deux âmes des fibres, d'une manière caractéristique par rotation de l'un ou des deux cylindres capillaires.

Filed: 1986-02-24
Abstract: Un procédé permet de déterminer la séquence d'acides aminés d'un polypeptide complémentaire d'au moins une partie d'un peptide ou d'une protéine originel. Un des aspects du procédé implique: (a) la détermination d'une première séquence de nucléotides d'un premier acide nucléique de codage de la biosynthèse d'au moins une partie du peptide ou de la protéine originel; (b) la détermination d'une deuxième séquence de nucléotides d'un deuxième acide nucléique dont les bases forment des paires avec la première séquence de nucléotides du premier acide nucléique, le premier et le deuxième acides nucléiques formant des paires dans des directions anti-parallèles; et (c) la détermination de la séquence d'acides aminés du polypeptide complémentaire par la deuxième séquence de nucléotides lue dans le même cadre de lecture que la première séquence de nucléotides. Le polypeptide complémentaire dont la séquence d'acides aminés est ainsi déterminée peut être obtenu par différents moyens tels que, par exemple, la synthèse chimique, la dérivation d'une protéine ou d'un polypeptide plus grand contenant ladite séquence d'acides aminés, ou, lorsque le deuxième acide nucléique est l'ADN, par l'insertion de la deuxième séquence de nucléotides dans un plasmide pour former un vecteur plasmide d'ADN de recombinaison. On transforme avec ce vecteur un organisme unicellulaire pour produire un organisme unicellulaire transformant qui synthétise biologiquement ledit polypeptide complémentaire. La nécessité de déterminer des séquences particulières de nucléotides peut être évitée, selon un aspect de l'invention, si l'on utilise la relation entre des acides aminés ayant des hydropathies complémentaires pour réaliser des substitutions dictées généralement par la complémentarité entre des nucléotides due à la formation de paires entre leurs bases.

Title: Self destruct double syringe
Inventor: COLONNA JOHN P
IPC: A61M5/50
Filed: 1992-04-07
Abstract: The present invention relates to a self destructing syringe which is only capable of being used once and is thereafter rendered useless. The syringe has a plunger (22) and plunger rod (28) which are interconnected by a coupling assembly (30). This coupling assembly includes a receiver (32) which is hollow and extends outwardly from the plunger and a connector (36) which is in the form of an enlarged head (42) on the end of the plunger rod which is adapted to be inserted into the receiver. In the preferred embodiment, the receiver has longitudinal splits along the side wall which form outwardly biased fingers (35). The coupling assembly also includes a locking sleeve (44) which is adapted to slide over the receiver to prevent the connector from being released from the receiver when the locking sleeve is in place. The locking sleeve remains in place as the plunger rod is pulled away from the needle to draw fluid into the syringe and moves away from the receiver as the plunger rod is pushed toward the needle to discharge the fluid from the syringe. The locking sleeve frictionally engages the inner wall of the housing and is wedged against the housing when the plunger rod is pushed towards the needle. Simultaneously, the fingers spring outwardly against the inner wall of the housing. Thereafter, there is nothing to hold the plunger rod in the receiver and if the needle is attempted to be used again, the plunger rod is released from the syringe rendering the syringe useless.
