Title: Locking clip system for securing panels together
Inventor: PETERSON KIRK A
IPC: F16B12/22
Filed: 1997-10-27
Abstract: A system for interlocking together two panel members comprises a washer member having first and second washer portions connected by a necked down portion and having a through bore for receiving a fastener. The washer member is fastened to a side of a first panel member. A keyhole slot is formed in a second panel member, the slot having a relatively large opening portion leading to a relatively narrow opening portion. An aperture is formed in the second panel member spaced from the keyhole slot to define a bridge portion between the aperture and slot. A clip member attaches with a snap fit to the bridge portion and spans the keyhole slot terminating in an abutment portion at its distal end. When the two panels are interconnected, the necked down portion of the washer member is positioned within the narrow portion of the keyhole slot with the abutment portion of the clip retaining the washer therein. The system thereby provides for interlocking two panel members in a convenient manner with few readily manufactured components.

Abstract: La présente invention concerne la séparation de complexes actifs définis à l'aide d'une caractéristique physicochimique particulière telle que la densité, la charge superficielle ou la grosseur des particules, de complexes formés par l'association d'un polynucléotide avec un constituant transfectant qui accroît l'activité de transfection, comme un lipide, un lipide cationique, un liposome, un peptide, un peptide cationique, un dendrimère ou un polycation. Dans un mode de réalisation préférentiel, les complexes polynucléotide-constituant transfectant subissent une ultracentrifugation pour diviser une ou plusieurs bandes correspondant à des complexes qui ont une interaction spécifique polynucléotide-constituant transfectant. Les complexes de polynucléotides ayant un constituant transfectant de type liposome cationique se divisent en deux bandes primaires qui correspondent à des complexes formés soit dans des conditions d'excédent de lipides, soit dans des conditions d'excédent de polynucléotides. Dans un autre mode de réalisation, les complexes polynucléotide-constituant transfectant sont divisés grâce à l'utilisation de l'électrophorèse transversale pour identifier les complexes ayant des interactions spécifiques et les séparer des constituants de départ en excédent.

Title: Adjustable wing plow
Inventor: NIEMELA CAL G
IPC: E01H5/06
Filed: 1998-03-18
Abstract: A plow assembly is disclosed for vehicles such as pickup trucks and tractors for moving snow or other materials. The plow assembly has at least one extendable, forwardly pivotable plow wing which is extendable on one end of a main plow by sliding movement along the front of the plow between a retracted and an extended position in which the plow wing is generally aligned with the plow front surface. The plow wing is also pivotally mounted on a hinge for movement between the extended position and a forwardly angled position in which the plow wing front surface extends at an angle to the plow front surface. A pair of fluid power cylinders are connected to the plow wing to move the wing between the retracted, extended and forwardly angled positions. In the preferred embodiment, an extendable plow wing is included on each end of the main plow with a pair of fluid cylinders connected to each of the respective plow wings. The fluid cylinders in each respective pair are operable independently of one another to move the plow wings independently between their respective retracted, extended and forwardly angled positions. When both plow wings are pivoted to their forwardly angled positions, the plow assembly has a general U-shape which facilitates pushing snow or other material without the snow slipping off the plow blade ends. The main plow may include a section formed from polymeric sheet material for weight reduction.

Title: Fault monitoring technique for programmable logic controllers
Inventor: MOWRY STEPHEN WEEKS JR
IPC: G05B23/02
Filed: 1996-12-11
Abstract: An isolated fault monitoring circuit for an AC port in an AC I/O module for a programmable logic controller is taught. Briefly stated, a bridge circuit is series connected to a fuse and an optocoupler. When the fuse which is in series with the AC input line is blown, the output of the optocoupler produces a voltage one-half of that during steady state operation thereby causing one of two comparators to go high which in turn causes an LED to light indicating a blown fuse. Should the AC input line be disconnected or otherwise not present, the optocoupler produces no output which thereby causes the second of the two optocouplers to have its output go high thereby causing a second of the two LEDs to light so indicating that condition. At any time during the fault condition only one of the LEDs will light, while no LEDs are lit during steady state operation.
