Title: Strip severing and transfer arrangement
Inventor: HAESSNER WINFRIED
IPC: B65H23/28
Filed: 1995-03-14
Abstract: A strip severing and transfer arrangement for an insertion strip to be threaded into a machine for manufacturing or processing of a web, comprises a pivotally supported guide plate having a transfer edge for guiding the insertion strip, a first blow element for applying an air blast to the top surface of the guide plate facing the insertion strip, a severing means and a second blow element in the region of the transfer edge of the guide plate, across which the insertion strip runs off the guide plate at a rear side of the guide plate facing away from the insertion strip for producing air flow which flows out across the transfer edge of the guide plate.     The insertion strip is optimally guided at high speeds at the start of the threading process, without fluctuations and lateral offset, permitting precise separation or severance.  The front edge of the insertion strip is accurately guided during the transfer to the follow-on arrangements, be it a guide-plate or rope shears, so that the threading process of the fed insertion strip can be assured with a very high degree of certainty.

Title: Injection molding apparatus with nozzle advanceable to mount side gate seals
Inventor: GELLERT JOBST ULRICH
IPC: B29C45/22
Filed: 1995-05-15
Abstract: Injection molding apparatus having several side gate seals extending radially from a heated nozzle. The nozzle has a locating flange portion which is received in an opening in the mold. This laterally locates the nozzle while allowing it to be advanced for mounting of the side gate seals and then retracted to an assembled position where it is longitudinally located by the side gate seals being received in the mold. Thus, the nozzle is longitudinally located in the same plane as the gates and in one embodiment a melt distribution manifold is free to float with the rear ends of the nozzles. This also provides for differences in the thermal expansion due to possible different operating temperatures.

Title: Method of positioning ophthalmic lenses
Inventor: KEENE DARREN S
IPC: B29C33/04
Filed: 1995-06-08
Abstract: A method of positioning an ophthalmic lens in a holder forming a concave recess, including the steps of conducting a fluid solution containing a surfactant into the recess, placing the ophthalmic lens in the recess, and positioning the holder so that gravity forces the lens into a predetermined position in the recess. The carrier and the lens may then be transported to a lens inspection position, where the lens may be inspected to determine if it is acceptable for consumer use. The surfactant reduces the friction and the hydrophobic attraction between the lens and the surface of the holder forming the recess, helping to insure that the lens is pulled into the desired, predetermined position in the recess.

Title: Retractable pop-up head rest usable with a vehicle passenger seat
Inventor: PATTERSON JAMES
IPC: B60N2/48
Filed: 1995-06-23
Abstract: A retractable pop-up head rest assembly is provided which is usable with a vehicle passenger seat. A head rest is mounted for vertical movement from a normally retracted position adjacent the seat to an extended operative position. The vertical movement of the head rest is provided by an elongated shaft which is slidable relative to the seat and carries the head rest and is movable therewith. The shaft is mounted for rocking movement by a gap formed in the seat. The spring is mounted below the head rest for resiliently urging the head rest to move vertically from the retracted position towards the extended operative position. A trigger member is mounted below the head rest for restraining the vertical upward movement of the shaft from the retracted position. The shaft is rockably movable between a first position and a second position. The trigger member also restrains the rocking movement of the shaft from the first position to the second position and is operable in response to a predetermined force being exerted thereon caused by the rapid deceleration of the vehicle so as to permit the shaft to rock from the first position to the second position thereby causing the spring to urge the shaft from the retracted position towards the operative position.

Title: Semi-solid metal forming method
Inventor: GARAT MICHEL
IPC: B22D18/02
Filed: 1995-01-13
Abstract: A semi-solid metal forming method comprising the steps of providing a thixotropic metal slug corresponding to the weight of metal to be used, heating slug to a semi-solid state until the liquid fraction gives the desired forming viscosity, transferring the slug to a pressure die-casting or forging press, and forming the slug by pressure die-casting or forging. According to the method, the viscosity of the slug is adjusted to the desired value by correspondingly adjusting the heating power by a quantity related to the resistance of the material to the forging punch or the plunger during the process of filling the forging die or the mould cavity. Said method is particularly suitable for forming thixotropic aluminium alloys.

Patent CA-2161801-A1 (CA)
Title: Method for polishing fiber optic ferrules
Inventor: LURIE EDWARD B
IPC: G02B6/38
Filed: 1994-06-01
Abstract: A method of polishing ferrules used in optical fiber connectors centers the apex of the spherical end face of the ferrule on the fiber axis. The invention is directed to ferrules whose ends are angled and generally spherical, providing angled physical contact (APC) between a pair of interconnected fibers. These ferrules commonly have a chamfer from the outermost diameter leading to the spherical, angled end face. In such prior art ferrules, the apex of the spherical end face does not coincide with the fiber axis, leading to a potential gap between the fiber ends which affects several performance factors, including insertion loss, stability and repeatability. The present invention provides several practical methods for imparting and APC finish to a chamfered ferrule while maintaining the apex of the spherical end face on the fiber axis.

Patent CA-2172001-A1 (CA)
Inventor: APPLING WILLIAM M
IPC: A61M39/00
Filed: 1996-03-18
Abstract: A luer-type adapter has a dual instead of a single set of engaging screw threads. A proximal and a distal screw thread on the hub engage proximal and distal screw threads on the collar of the connector to provide at least twice the engaging or sealing force between the tapered surfaces of the stem and hub which are forced together by rotating the collar relative to the hub to engage the two sets of threads. The diameters of the engaging distal screw threads have to be sufficiently great so that the proximal screw thread on the hub can pass under the distal screw thread on the collar in order to effect proximal as well as distal engagement. An O-ring mounted on an untapered distal segment of the stem engages an untapered inner hub surface to provide additional sealing force which is particularly useful where gas is being provided through the adapter.
