Title: Adhesive closure identification bracelet
Inventor: PETERSON DEAN D
IPC: G09F3/00
Filed: 1995-01-30
Abstract: An identification  bracelet (10) includes an integral adhesive closure (30) which permits the bracelet to be formed in a virtually uniform thickness.  The bracelet is formed of laminates (20, 22) that are relatively  permanently  bonded to each other over a majority of the body (11) of the bracelet, with a movable cover portion (32) formed as part of one or more of the laminates.  The cover portion is adapted to be moved from a covering relationship  to a non-covering relationship  with respect to an adhesive (24) disposed between two or more of the laminates. The cover may be removable from the bracelet, and may  be configured  with gripping portions (94) to permit ready manipulation  of the cover from the aforesaid covering relationship to the non-covering  relationship.  A plurality of such bracelets may be provided in a flexible strip (100), and a method of use of such a strip includes dispensing  the strip through a printer (106) or similar indicia-producing  device and detaching each encoded bracelet from the strip and affixing the same to a person or object corresponding to the encoded information.

Title: Electrical connector and method of making
Inventor: STIDHAM CURTIS R
IPC: H01R4/36
Filed: 1996-07-31
Abstract: A low resistance electrical connector comprising a flat bar having multiple lateral fingers projecting from the bar to form flat compression pads for attachment of electrical connectors, and an insulating housing surrounding said bar and including relatively short cylindrical projections enclosing a short extent of each finger and presenting a circular shoulder at the proximal end of each finger or the inner end of each compression pad so that a rocket may telescope over the shoulder and seal the connection to each pad. The number of fingers projecting from each bar may vary and they may project from one or both lateral sides of the bar. The connector is made by laser or waterjet cutting a flat sheet or bar of conductive metal such as copper, aluminum or a laminate to form a blank. The sheet is cut to avoid excessive scrap so that the space between fingers becomes the fingers of another blank. The blank is deburred and placed in a mold to formthe insulating housing and cylindrical projections. Holes are drilled and tapped in the projecting pads either before or after molding.

Abstract: There is provided architectural moulding apparatus (10) including a supporting frame assembly (11) and a paper roll assembly (12) which delivers a continuous paper web (13) via tension and drive rollers (14) to an adhesive applicator (22) where hot melt pressure sensitive adhesive is deposited on the web (13). The glue coated paper web (13) passes over roller (24) to a profiled polystyrene core (16) at a set-up roller assembly (25). The core (16) is delivered by a core feed assembly (15) which is adapted to receive lengths of the core (16) in abutting relation. The set-up roller assembly receives the core (16) and urges the paper web (13) glue side first into the core (16) to form the moulding assembly (32) which passes to a laminating roller assembly (33) adapted to urge the glue covered web (13) into intimate contact with the profile face of the core (16). The moulding assembly (32) then passes to a series of rollers (38) adapted to progressively fold and roll the web (13) to completely wrap the core (16). The moulding assembly (32) then passes to a finishing roller assembly (37), a consolidating roller assembly (40), and a final finishing roller (41), to ensure bonding integrity between the web (13) and the core (16). The finished moulding assembly (32) passes to a flying shear assembly (42) adapted to cut the continuous moulding assembly (32).

Inventor: LUST VICTOR
IPC: B29L11/00
Filed: 1997-08-15
Abstract: An injection molding process for molding an assembly of a frontcurve molds in a plurality of unitary solid piece of polymer in which plurality of frontcurve molds are arranged symmetrically around a single center polymer injection gate. In this arrangement the molten polymer flows radially outwardly therefrom uniformly in all directions to the four frontcurves to form one common molded piece of polymer. In a compression injection molding process, the pressure on the molten polymer is maintained relatively constant, and the mold is mechanically collapsed during the molding operation. The present invention molds an assembly of frontcurve molds in a manner in which there is a significant reduction of residual stress locked into the resultant assembly of frontcurve molds. This results in a significant reduction in warpage and shrinkage of each frontcurve mold, which is not optically stressed, and results in a subsequent casting of an ophthalmic lens which is not optically stressed. Moreover, the assembly of frontcurve molds can function as its own support pallet for product placement and alignment purposes during subsequent production operations.

Title: Wholly microfabricated biosensors and process for the manufacture and use thereof
Inventor: COZZETTE STEPHEN N
IPC: B01D/
Filed: 1989-11-14
Abstract: An efficient method for the microfabrication of electronic devices which have been adapted for the analyses of biologically significant analyte species is described. The techniques of the present invention allow for close control over the dimensional features of the various components and layers established on a suitable substrate. Such control extends to those parts of the devices which incorporate the biological components which enable these devices to function as biological sensors.  The materials and methods disclosed herein thus provide an effective means for the mass production of uniform wholly microfabricated biosensors.  Various embodiments of the devices themselves are described herein which are especially suited for real time analyses of biological samples in a clinical setting. In particular, the present invention describes a method of establishing a dispensed layer onto a substantially planar surface by preparing a fluid composition suitable for loading into a movable microsyringe assembly loading the composition into the assembly, which comprises a reservoir, a microsyringe needle, means for delivering the composition to the needle, means for forcing controlled amounts of composition to form an emerging droplet of a predetermined volume on the needle tip, and means for controlling the multidirectional movement of the assembly, contacting the droplet with a preselected area of substantially planar surface; and retracting the assembly such that the droplet provides a dispensed layer of composition having predictable and reproducible dimensions on that surface.
