Inventor: SMITH DONALD
IPC: B65B13/06
Filed: 2001-03-15
Abstract: Apparatus and methods for wire-tying one or more objects. A wire accumulating and feeding mechanism feeds the wire axially through the hollow axle of an accumulator drum and then out to a drive wheel. The wire is wrapped around the periphery of the drum to accumulate the wire during tensioning. A wire gripping mechanism is a simple, economical device including a gripper block having a wire receptacle formed therein, an opposing wall positioned proximate the wire receptacle, and in one embodiment a tapered gap formed in the gripper block proximate the wire receptacle and opposite from the opposing wall, and a gripper disc mounts in a gripper release lever constrained to move within the tapered gap and frictionally engageable with the length of wire disposed within the wire receptacle, the gripper disc being driven into the tapered gap by frictional engagement with the length of wire and pinching the length of wire against the opposing wall when the drive motor is operated in the tension direction. In an alternative embodiment the gripper release lever pinches the wire against the gripping wall. In another embodiment, an apparatus includes a track assembly including multiple modular segments forming a corner of the track. In yet another aspect, a twisting assembly includes a twist motor coupled to a rotatable twist axle having a plurality of cams attached thereto, the primary functions of the twisting assembly being cam-actuated.

Title: Local call-timing cct. for telephone exchange - has control line connecting to call-timing-pulse counter
IPC: H04M15/10
Filed: 1974-04-18
Abstract: The local call-timing circuit, for telephone exchanges, has a control line passing through an additional unit and switched to connect with the counter that counts the call-timing pulses. The control line ahs a capacitor coupled to it such that the counter is set at the beginning of a conversation when the constant count-voltage is applied to the appropriate connecting line. When the called subscriber replaces his hand-set, signals to this effect pass to a detector in the additional unit which then initiates the control line's disconnection. The installation does not require any far ranging modification of existing equipment.

Title: Peptides imitant un epitope cryptique de gp41 de hiv-1
Inventor: STIEGLER GABRIELA
IPC: C07K14/16
Filed: 2002-09-09
Abstract: L'invention porte sur la neutralisation d'anticorps anti-HIV-1, plus particulièrement sur mAb 4E10-IgG1, qui présente un pouvoir de neutralisation de HIV-1 comparable à celui de mAb 2F5 et 2G12. 4E10-IgG1 se lie à un nouveau C-terminal d'épitope conservé (NWFDIT) de l'épitope ELDKWA reconnu par 2F5. Il semblerait que les deux épitopes soient des épitopes cryptiques à l'intérieur d'une zone accessible dans une fusion cellulaire virale seulement à l'état intermédiaire. 4E10-IgG1 neutralise puissamment des souches adaptées à la culture de tissus mais aussi des isolats primaires de différentes variantes, y compris A, B, C, D et E, comportant des virus qui ne se sont pas révélés résistants à 2F5. Aucun des isolats testés ne s'est montré résistant aux deux anticorps anti-gp41. Par conséquent, cette invention concerne aussi des peptides contenant l'épitope 4E10, et des compositions fabriquées à partir de ces peptides, ainsi que des anticorps anti-idiotypiques qui réagissent avec la paratope de 4E10-IgG1, et des compositions contenant un anticorps anti-idiotypique, facultativement en combinaison avec une peptide contenant l'épitope 4E10, facultativement en combinaison avec un autre anticorps neutralisant tel que 2F5 et/ou 2G12.
