Title: Making a data-carrying optical disk
Inventor: EICHLSEDER MARTIN
IPC: B29C45/40
Filed: 1991-03-07
Granted: 2000-08-08
Abstract: An optical disk having a pair of axially oppositely directed faces and an annular outer periphery is made by first forming a mold cavity corresponding to the shape of the disk between a pair of axially spaced parts and a demolding ring sandwiched between the parts. The cavity is then filled with a hardenable resin such that the parts form the respective faces and an inner periphery of the ring forms the outer periphery of the disk and the resin is at least partially hardened in the cavity. The parts are then axially oppositely separated from each other and from the disk to leave the disk in the ring with both of its faces exposed and the ring is then transversely displaced with the disk engaged in it out from between the mold parts. The disk is then cooled and shrunk such that its outer periphery separates from the inner periphery of the ring and the disk separates from the ring.

Title: Binary image processing for decoding self-clocking glyph shape codes
Inventor: BLOOMBERG DAN S
IPC: G06V30/224
Filed: 1991-06-12
Granted: 1998-04-14
Abstract: Binary image processing techniques are provided for decoding bitmap image space representations of self-clocking glyph shape codes of various types (e.g., codes presented as original or degraded images, with one or a plurality of bits encoded in each glyph, while preserving the discriminability of glyphs that encode different bit values) and for tracking the number and locations of the ambiguities (sometimes referred to herein as "errors") that are encountered during the decoding of such codes.  A substantial portion of the image processing that is performed in the illustrated embodiment of this invention is carried out through the use of morphological filtering operations because of the parallelism that is offered by such operations.          Moreover, the error detection that is performed in accordance with this invention may be linked to or compared against the error statistics from one or more alternative decoding process, such as the convolution filtering process that is disclosed herein, to increase the reliability of the decoding that is obtained.

Title: Address management for remote terminals in digital loop transmission systems
Inventor: BLEVIN JOHN HARRIS
IPC: H04L29/12
Filed: 1991-11-21
Granted: 1997-04-22
Abstract: Disclosed is a method and apparatus for identifying remote terminals which are networked in a digital loop transmission on system. A Site Interface Unit (SIU) at one of the remote terminals acts as a master. The Bank Controller Unit (BCU) at each remote terminal calculates a 16-bit number based on its 60-byte serial number. A binary search is then performed by the SIU to determine the calculatednumber of each BCU, and an address is assigned to each remote terminal by the SIU. Any conflicts in the numbers initially calculated are resolved by transmission of the full 60-byte serial number.

Title: Printed circuit board assembly handle/stiffener
Inventor: GRAMMAS JAMES J
IPC: B23K1/08
Filed: 1992-01-03
Granted: 2001-11-20
Abstract: A printed circuit board handle is disclosed for use with a printed circuit board.

Title: Method of fabricating monomode active strip optical waveguides for optical telecommunications
Inventor: COGNOLATO LIVIO
IPC: H01S3/07
Filed: 1992-10-14
Granted: 1996-07-09
Abstract: In order to fabricate monomode active strip optical waveguides  for  optical  telecommunications,  a  layer  of vitreous  soot  is  deposited  on  a  substrate  and  is impregnated with a solution of a precursor of a rare-earth dopant, and radiation with a wavelength in an absorption band of the dopant is focused on the soot, and moved along a trajectory corresponding to the configuration desired for the guide, thereby forming a vitrified strip.  The soot may be pre-doped with a refractive index raising dopant, or a precursor of such a dopant may be included in the solution. The substrate may be of a polygonal tubular cross-section, and the soot deposited on an inside surface.  This enables several waveguides to be formed at once, and protects the soot layer from contamination.

Title: Vibration damping device for hammers
Inventor: VAUGHAN HOWARD A JR
IPC: B25D1/12

Granted: 2004-01-20
Abstract: In a claw-type hammer, a shock-absorbing device is provided which includes an elongate elastic band or cord which captured within grooves of a hickory plug in regions which abut against internal surfaces of a socket into which the plug is press-fit.   The plug is dimension and configurated in relation to the socket in the hammer head to provide at least some degrees of freedom of movement of portions of the elastic cord so that the elastic portions can vibrate or oscillate substantially independently of the natural oscillatory vibrations of the hammer head caused by impact. The tendency of the elastic cords is to at least to partially cancel or neutralize and, therefore, dampen the natural vibrations of the hammer head.

Title: Refrigerant coil apparatus and associated condensate drain pan structure
Inventor: COX JIMMY L
IPC: F24F13/22
Filed: 1993-03-10
Granted: 1996-10-08
Abstract: Using a series of  identically  sized,  single row,  single circuit refrigerant coil modules, fin/tube refrigerant coils of different nominal air conditioning tonnages are constructed by arranging different numbers of the identically sized modules in accordion-pleated orientations, with each modular coil having the same depth in the direction of intended air flow across the coil.        Compared to conventional "A" coils used on the indoor side of air conditioning circuits, these accordion-pleated modular coils are more compact in the air flow direction, provide more coil surface area, permit lower coil face velocities with higher fin density, and significantly reduce the overall coil manufacturing costs since only one size of coil slab needs to fabricated and inventoried to later assemble refrigerant coils of widely varying nominal air conditioning tonnages.   A specially designed one piece molded condensate drain pan structure may be releasably snap-fitted onto the underside of the modular refrigerant coil, and is provided on opposite sides with support structures that are configured to slidably receive an opposed pair of interior rail members within the housing of an indoor air conditioning unit as the connected drain pan structure and modular coil are operatively inserted into the housing through an access opening therein.  Accordingly, the drain pan may be secured to the modular coil, and the coil/drain pan assembly mounted within the air conditioning unit housing, without the conventional necessity of using sheet metal screws to effect these connections.

Title: Detection signal evaluation at varying signal levels
Inventor: PILDNER REINHART KARL
IPC: G08B29/18
Filed: 1993-07-06
Granted: 1998-09-01
Abstract: An arrangement and method for processing signals from infrared intrusion detectors is disclosed which allows the signal to be processed at different amplitude levels to recognize different signal characteristics.  This capability to analyse the signal at different values allows further customizing of the system for particular applications and provides information useful in recognizing and dealing with unwanted signal changes.  The system also accommodates increasing the effect on certain portions of the signal when considering the net overall effect of the signal.  This results in more signal information being available and higher accuracy in detecting actual human intrusions in the monitored space.

Granted: 1998-08-25
Abstract: A  portable  radiant  heating  apparatus  is  provided  for performing splices in waterstops. The heating apparatus includes a pair of radiant quartz heating elements that are mounted intermediate the end members of a generally rectangular-shaped frame.   The heating elements  are preferably positioned  in parallel fashion one above the other.  Heat deflecting shields are mounted to the top and bottom frame members proximate to the heating elements to concentrate the radiant heat along the sides of the heating apparatus.  A splicing operation is performed by positioning the ends of two waterstop sections to be joined adjacent to and on opposite sides of the heating apparatus so that the ends of the two waterstop sections are exposed to the radiant heat from the heating apparatus.   Once the waterstop sections have been sufficiently heated to cause the ends thereof to begin to melt, the waterstop sections are removed from the heating apparatus and the ends therefor pressed and held together until the waterstop material cools, thereby forming a water-tight seam.
