Title: Apparatus for dissipating wave energy
Inventor: DORRELL DONALD EDWARD
IPC: E02B3/14
Filed: 1993-02-24
Granted: 2003-08-19
Abstract: A structure for dissipating the energy of waves impinging on a shore is disclosed which comprises one or more rows of mo-dules (10) positioned adjacent the shore. Each module incorporates a number of vanes (49, 49', 49", 126). The vanes are shaped and spaced so that a number of venturi passages (94) are defined between the vanes. Each vane has a frontal portion (49, 68', 68") which faces away from the shore, and is inclined from the vertical so that it slopes away from the shore to define an entrapment chamber (96, 96', 96") which forces an oncoming wave to pass through the venturi passages rather than over the module or be ref-lected. The sides (80) of the passages converge from front to back. A  longitudinally extending hub (50) causes the passages to converge also in the vertical direction. Each vane may be X-shaped and substantially symmetrical about a vertical plane through its centre. The modules are cast from a cementitious material and may incorporate a number of the vanes joined together at the hub which is located at the centre of the X. The vanes may be joined together at their upper and lower ends by cross members (28, 30, 32, 34, 128, 130, 156, 158). The passages may incorporate cross vanes (106) which divide the passage into sub-passages. Other vane shapes are disclosed. The vanes may be individually fabricated.

Inventor: HUBER KLAUS B
IPC: E21B23/04
Filed: 1995-06-06
Granted: 2005-12-13
Abstract: A firing head adapted to connected between a coiled tubing and a perforating gun, is sized and shaped to enable it to move freely within a tubing string in the wellbore, may be actuated by fluid pressure within the coiled tubing, and includes a circulation and recirculation feature wherein wellbore fluid may be circulated through the firing head between the coiled tubing and an annulus around the tubing string, the circulation taking place either before or after detonation of the perforating gun. Three firing heads are discussed. One such firing head is a Circulation Direction Firing (CDF) Head. The CDF firing head circulates fluid from the wellbore to the coiled tubing and depresses a piston. Then, fluid pressure from the coiled tubing lifts the piston uncovering locking balls and propelling a firing pin to a booster of a detonating cord detonating the CDF firing head. Fluid circulation from the coiled tubing to the wellbore annulus begins after the CDF firing head detonates. Another such firing head is a Circulation Ball Firing (CBF) Head.  The CBF firing head circulates fluid from the wellbore to the coiled tubing, receives a ball, and uses fluid pressure in the coiled tubing to lift a piston, uncover the locking balls and detonate the CBF  firing head. Another such firing head is a Ball Actuated Circulation Firing (BCF) Head. The BCF  firing head circulates fluid from the wellbore to the coiled tubing, receives a ball from the wellbore surface, and uses fluid pressure in the coiled tubing to push a piston downwardly which uncovers the locking balls and detonates the BCF firing head. Recirculation is permitted after the firing head detonates.

A second distance, denoting the distance between outer edges of the complimentary pads is selectd as the maximum distance between outer edges of the terminals of anticipated surface mount components.  A second distance, denoting the distance between outer edges of the complimentary pads is selected as the maximum distance btween outer edges of the terminals of anticipated surface mount components.  Manufacturing tolerances may be incorporated into each of these dimensions.  A design process is described which considers the dimensions of surface mount components which are likely to be substituted and manufacturing tolerance which may be added to or substracted from the dimensions of the uni-pad.

Title: Molecular tagging system
Inventor: BRENNER SYDNEY
IPC: C12N15/10
Filed: 1995-10-12
Granted: 2003-12-16
Abstract: The invention provides a method of tracking, identifying, and/or sorting classes or subpopulations of molecules by the use of oligonucleotide tags.  Oligonucleotide tags of the invention each consist of a plurality of subunits 3 to 6 nucleotides in length selected from a minimally cross-hydridizing set.  A subunit of a minimally cross-hybridizing set forms a duplex or triplex having two or more mismatches with the complement of any other subunit of the same set. The number of oligonucleotide tags available in a particular embodiment depends on the number of subunits per tag and on the length of the subunit. An important aspect of the invention is the use of the oligonucleotide tags for sorting polynucleotides by specifically hybridizing tags attached to the polynucleotides to their complements on solid phase supports. This embodiment provides a readily automated system for manipulating and sorting polynucleotides, particularly useful in large-scale parallel operations, such as large-scale DNA sequencing, mRNA fingerprinting, and the like, wherein many target polynucleotides or many segments of a single target polynucleotide are sequenced simultaneously.

Abstract: A low cost LED array is formed from a plurality of modular units that are snapped together. Each modular unit consists of one or more U-shaped lead frame substrates which are overmolded with a thermoplastic insulator material (27, 29, 30). The lead frame substrates act as heat dissipators. The LEDs (32, 34, 36, 38, 40) are then bonded onto the upper surfaces of the lead frame substrates. A reflector unit is separately molded and has one cone-shaped reflector (44, 46, 48, 50, 52) for each light emitting diode. The lead frame unit such that the LED is disposed in the center of each cone. Each of the reflector units has several dovetail-shaped connectors (54, 56, 58, 60, 62, 64) which enable the completed module to be connected to adjacent modules to form the array. The modules are then electrically connected together in series or in parallel according to the particular application. The arrays may be used for plant growth or in photodynamic therapy.
