Granted: 2005-11-08
Abstract: There is disclosed a method of detecting a mutation in a CD40 ligand gene, comprising isolating nucleic acid from an individual, selectively amplifying nucleic acid derived from the CD40 ligand gene, and analyzing the amplified nucleic acid to determine if there is a mutation (or mutations) in the CD40 ligand gene. The ability of a CD40 ligand protein expressed from the gene may be determined. Methods of treating a syndrome that results in elevated levels of serum IgM  and diminished levels of all other isotypes of immunoglobulins are also disclosed. Also disclosed are non-human animals that lack functional CD40 ligand as a result of gene targeting technology.

Abstract: A process for injection molding of thermoplastic materials which includes a nozzle body having a bore to provide a flow path for molten thermoplastic. One end of the nozzle body is adapted for connection with a sprue of an associated mold body, and the other is adapted for connection with an end of an associated injection molding machine. The nozzle body has a shut-off valve fluid pin housing adapted for reciprocating movement in the nozzle bore to control the flow of plastic through the nozzle body. The shut-off valve fluid pin housing also includes a body having a fluid pin with a tip portion and the other end of the fluid passage communicating with a source of two pressurized fluids, one in vapour and liquid phase and another in gas. The shut-off valve is actuated to allow thermoplastic material to flow and subsequently a first pressurized fluid vapour is allowed to flow to form a hollow cavity in the thermoplastic material and then terminated and a second fluid which is a gas is allowed to flow into the cavity or it may be followed by the liquid of the first fluid vapour. After the thermoplastic material has set, the pressurized fluid is vented through the fluid pin housing passage into a fluid condenser for recovery of the vapour and liquid and then into atmosphere.

Title: Anti-snag latch assembly for a connector
Inventor: LAMPERT NORMAN ROGER
IPC: H02H7/22
Filed: 1996-06-28
Granted: 1999-02-02
Abstract: A connector (10) terminates an optical cable (30) and includes a cylindrical ferrule (140) installed in a plastic base member (150) to form a fiber-holding structure. This structure includes a small passageway along its central axis forholding an optical fiber, and is mounted within a housing (110) that includes a cable-entrance end for receiving the optical cable and a plug end for insertion into a jack receptacle (40). The housing includes a cantilever latch (120) that is mounted on a side surface of the housing and is used to secure the connector to the receptacle. The fixed end (125) of the cantilever latch is positioned toward the plug end of theconnector, and the free end (124) of the cantilever latch extends toward the cable-entrance end of the connector. The housing further includes a cantilever trigger (130) which slidably engages the latch to move it downward and thereby release the connector from the receptacle. The fixed end (135) of the trigger is positioned toward the cable-entrance end of the connector and the free end (134) of the cantilever trigger extends toward the plug end of the connector. The trigger forms an acute angle (.beta.) with the central axis (101) of the housing that points in a direction away from the plug end of the connector toward the cable-entrance end so that when the cable is pulled backward through a concentrated a of cables and wires, the trigger prevents the latch from snagging. The novel anti-snagging feature is also incorporated into an RJ-type electrical connector (800).

Abstract: The present invention relates to a roofing tape which allows roofers to determine and consistently apply the proper reveal space of shingles on any roof without measurement. A roofing tape (6) includes a start indicator (12), a first line indicator (14) and a plurality of series of indicia (16-24) on its front surface (10). The first line indicator (14) is located at a distance from the start indicator (12) equal to the height of the roofing shingles less the overhang requirement of the roofing shingles. Each series of indicia (16-24) is arranged longitudinally along the roofing rape. Each series of indicia (16-24) has equal intervals (RS1-RS5) between the first line indicator (14) and the first indicator (16) in the series and between consecutive indicia in the series. The intervals (RS1-RS5) in each series correspond to a spacing within the reveal space tolerance range of the roofing shingles. The roofing tape preferably includes eave adjustment hash marks so that the tape may be adjusted downward to cover all the areas along an irregular eave. The roofing tape preferably includes an applicator which helps extend the tape along the roof aids in selecting the appropriate indicia for the particular roof, and indicates the line where the bottom of the last course of shingles should be laid. The present invent ion eliminates the need for a roofer to perform measurem ents and trial and error calculations in determining the correct reveal space for a roof, eliminates the possibility for creep, and facil itates the installation of shingles on uneven and intersecting roofs and roofs with oth er irregularities.

Abstract: A method and apparatus for manufacturing an improved bag for the cultivation of muschroom spawn is provided. The bags have continuous gas permeable sealing strips (80) sealed to the inside walls of the bags which cover openings (52) in the bags, so as to allow the bags to be vented without loss of moisture. The openings (52) and sealing strips (80) are positioned close to the top and bottom of the bags so as to maximize air flow through the muschroom spawn without creating dry spots, thereby improving spawn yield. The apparatus includes rollers (70, 72) for dispensing plastic film and at least one continuous hydrophobic strip of material (80). A series of apertures (52) are punched by cutting dies (50) in the film, and a vacuum system (60) removes the cut out portions. The strip of material (80) is positioned over the apertures (52) and sealed by sealing dies (90) over them, so as to enclose the apertures (52). A cutting dies cuts off the film and strips (80). A conventional bag making machine forms the bags.

Abstract: An actuator for a high voltage switch has a bellcrank and a rocker pivotally mounted to a frame and connected to one another by opening and closing springs. The bellcrank is linked to the movable actuating element of a high-voltage switch. During switch closing, a catch holds the bellcrank in it open position while the operator pivots  the  rocker  towards  a  closed  position,  thereby stretching the closing spring and storing energy in it, while allowing the opening spring to go slack.   When the rocker reaches a closing unlatch position, the bellcrank is released and moves rapidly toward its closed position, thus closing the switch.   The opening action is similar. The bellcrank and rocker may cooperatively define channels for constraining the springs.

Abstract: A shaped charge includes a main body of explosive and a primer adapted to detonate said main body of explosive. In accordance with the present invention, the main body of explosive now includes an explosive composition known as sym-triaminotrinitrobenzene (TATB) and, since TATB is not sensitive enough to be a primer, the primer must consist of an explosive composition which is more sensitive than TATB. It has been discovered that, when the main body of explosive in a shaped charge is modified to include the explosive composition known as TATB and when the primer includes an explosive other than TATB, such as HNS or NONA or PYX or HMX, or a mixture of HNS or NONA or DODECA or PYX or HMX and TATB and when the shaped charge is detonated, the detonated charge will produce a jet that is longer in length than the jet associated with prior art shaped charges which did not have a main body of explosive that included TATB. As a result, when the longer jet is produced from the shaped charge of the present invention, that has been modified to include a main body of explosive comprising TATB and a primer which is more sensitive than said TATB, the longer jet will produce a longer perforation in a formation penetrated by a wellbore and, as a result, an increased quantity of wellbore fluid will be produced from the perforated formation.      A detonating cord could also include the TATB explosive.
