Abstract: A nosepiece assembly for blind pull-through riveting tool has long nosepiece jaws  (11a,  11a)  for access in to deep, narrow cavities.   The inside  of  the nosepiece  assembly is provided with means for locking the jaws together at least when a  rivet  is being  installed.    The  locking means  comprises frusto-conical locking face (35) on the front end of a tube (34) fixed to the tool barrel (18), co-operating with two half frusto-conical faces on the inside of the jaws.   The locking faces are normally urged out of engagement by the spring (20) and are urged in to locking engagement by the rearwards axial force exerted on the jaw anvil (25) by the head (33) of the rivet being installed.   In a modification,  the spring  (20) normally urges the locking faces (35, 36) into engagement, and they are urged out of engagement by the next rivet being fed forwardly through the anvil parts (13, 13).

Abstract: A method of making an end stop for a slider of a fastener structure for a thermoplastic bag. The fastener structure comprises a pair of flexible plastic strips adapted to be connected to the walls of the bag and having reclosable interlocking male and female profile elements on the respective strips and a slider straddling the strips for opening and closing them. The method comprises clamping together a pair of the flexible plastic strips between clamps at a seal area in the region intended to form an end of the strips, the clamps having pockets therein adjacent the profile elements at the seal area. The profile elements are several and heated at the seal area with a heated knife to transform the severed ends of the profile elements into molten material; the molten material is pressed into the pockets in the clamps with the heated knife thereby increasing the thickness of an area of the strips adjacent the seal area to provide a protruding end stop for preventing movement of the slider past the ends of the

Title: Telephone system communication mechanism employing central office sleeve lead
Inventor: SULLINS LESLIE A
IPC: H04M3/30
Filed: 1992-04-03
Granted: 2002-09-24
Abstract: A data communication and sleeve lead control apparatus provides auxiliary signalling between a no-test trunk control unit (12), and another unit such as a pair gain unit (14) which is coupled with the link between the control unit and the no-test trunk, while maintaining stability of the sleeve lead (5) monitored by the no-test trunk ( 16). The apparatus is installed within the pair gain unit, and effectively isolates the sleeve lead (5) to the no-test trunk (16) from sleeve lead (5) to the no-test trunk control unit (12), so that, the data communications between the. control unit and the pair gain unit are transparent to the no-test trunk (16). During a prescribed sleeve lead current flow state, e.g. high resistance or low current flow, controlled interruption of sleeve lead current between the control unit and the pair gain unit effectively modulates the state of the sleeve lead therebetween; but does not change the intended current flow state applied by way of the sleeve lead output port to: the no-test trunk.

Abstract: The manually-operated balloon stuffing device has a minimum number of parts and is inexpensive to manufacture. The device includes a manual pump consist-ing of inner and outer cylindrical tubes, and a check valve in each tube that permits the passage of air in only a single direction within its respective tube. In a first embodiment, a balloon stuffing item is placed in an end of the inner tube, and the open balloon end is stretched over that tube end. The outer tube is then reciprocated along the longitudinal axis of the inner tube to pump up the balloon. The outer tube is then removed and a push rod pushes the sliding check valve, which in turn pushes the stuffing item into the inflated balloon. In an alternate embodiment, a large hollow adapter tube is placed on the end of the inner tube, and the open end of the balloon is stretched over the open end of the adapter tube. After the balloon is inflated, a push rod pushes the sliding check valve, which in turn pushes an extension rod, the latter moving the stuffing item into the balloon. In yet a third embodiment, the need for a push rod and a slidable check valve is elimi-nated by using a connector between the tube in which the item is placed on the upper end of the inner tube. Once the balloon is inflated as before, the inner tube is pushed through the third hollow tube, thereby pushing the item into the balloon.

Title: Enantiomerically pure .beta.-d-(-)-dioxolane-nucleosides
Inventor: CHU CHUNG K
IPC: C07D473/30
Filed: 1991-12-05
Granted: 2007-08-21
Abstract: An asymmetric process for the preparation of enantiomerically pure .beta.-D-(-)-dioxolane-nucleosides. The enantiomerically pure dioxolane nucleosides are active HIV agents, that are significantly more effective than the prior prepared racemic mixtures of the nucleosides. The anti-viral activity of the compounds is surprising in light of the generally accepted theory that moieties in the endo conformation, including these dioxolanes, are not effec-tive antiviral agents. The toxicity of the enantiomerically pure dioxolane nucleosides is lower than that of the ra-cemic mixture of the nucleosides, because the nonnaturally occurring .alpha.-isomer is not included. The product can be used as a research tool to study the inhibition of HIV  in vitro or can be administered in a pharmaceutical composition to inhibit the growth of HIV in vivo.

Granted: 1998-08-18
Abstract: 2118321 9419215 PCTABS00033 The present invention is a tubular structure (11) which inflates upon side or oblique vehicle impact to protect the occupants of a vehicle such as an automobile. The structure is mounted in its undeployed state along the periphery of the vehicle's side pillars (20, 21) and roof rail (23). The primary component of the present invention is a braided tube (15) linked to a gas generator (22). When a side impact is detected, the gas generator (22) is ignited, inflating the braided tube (15). As the braided tube (15) inflates, the diameter of the tube (15) increases and its length decreases. The tube (15) then pulls out of its storage location and forms a taut, semi-rigid structural member across the vehicle's side window (24).
