Patent CA-2085440-A1 (CA)
Inventor: NIMBERGER SPENCER
IPC: F16L37/32
Filed: 1992-12-15
Abstract: An improved system and method are provided for normally interconnecting a stationary flow line and a flexible flow line, and for automatically separating the flow lines in response to movement of the flexible flow line in excess of a preselected limit. A connection comprises a socket housing sealed to one flow line and a ball housing sealed to another flow line. The housings are separated automatically when a lateral force is transmitted through the flexible flow line to cause excess pivoting movement of one housing related to the other housing. The connection of the present invention is particularly useful for preventing rupture of a flow line during an intermittent pullaway of a portable vessel with respect to a stationary holding tank. In one embodiment, the connection includes at least three ball swivel surfaces for mating engagement with a socket swivel surface. Valve members in each of the housings are held out of engagement with respective seating surfaces when the housings are mated, and automatically close to prevent fluid loss when the housings separate. A seal is provided for maintaining sealed engagement between the ball housing and socket housing when the ball housing normally pivots within a preselected arc limit with respect to the socket housing. The elastomeric seal preferably engages a seating surface forming a portion of an imaginary sphere having a center coincident with a sphere which defines the ball swivel surface and socket swivel surface.

IPC: C12Q1/68
Filed: 1991-09-20
Abstract: A method for the identification of compounds as inhibitors of oncoprotein action is described. A compound is identified as an inhibitor of oncoprotein action based on its ability to modulate the transcription of a reporter gene. Transcription of the reporter gene is dependent upon the binding of a fusion oncoprotein to a specific DNA binding element positioned upstream of the reporter gene promoter. The fusion oncoprotein contains a transcriptional regulatory domain from an oncoprotein and a DNA binding domain from a different protein.

The Magic-Tee comprises a ground plane interposed between dielectric printed circuit boards. The outermost surface of one of the boards carries a Tee circuit comprising microstrip branch arm conductors with a microstrip conductor projecting transversely from its middle, the Tee junction, to form the leg of the Tee.      The outermost surface of the other board comprises a line in the form of a microstrip conductor. An aperture is provided in the ground plane at a position between the Tee junction and an underlying part of the line conductor provides coupling between the line conductor and the Tee junction. Various Tee junction configurations, such as Y or .DELTA., may be implemented also. The magic Tee may be an integral part of an MIC or MMIC device.

Filed: 1992-11-12
Abstract: n générateur de tension de référence peut fournir à des RAM (mémoires à accès direct) une tension de référence (généralement à mi-chemin entre une tension d'alimentation et un potentiel commun), avec des caractéristiques de suiveur améliorées. Quand la tension d'alimentation et(ou) la condition de charge des RAM sont sensiblement modifiées, la tension de référence est rapidement ajustée par des FET à commutation dynamique, soit au niveau de la masse, soit au niveau de la source. Dans des conditions équilibrées, lorsqu'il ne passe essentiellement pas de courant dans les FET, la consommation globale d'énergie est faible.

Title: Integral fastening system
Inventor: HARAGA GEORGE N
IPC: F16B5/07
Filed: 1993-10-19
Abstract: Abstract of the Invention A fastening system for securing a metal plate to a plastic sheet is integrally formed from the material of the metal plate. An extrusion punch forms a cylindrical shaped lip which is located in a corresponding hole in the plastic sheet. The end of the cylindrical shaped lip is then peened over to provide an annular section that traps and thus secures the metal plate to the plastic sheet. The present invention thus provides a low cost lightweight fastening system eliminating the need to match and apply individual conventional fasteners with particular components. The fastening system is particularly useful for fastening a metal backing plate to a hood assembly. The hood assembly includes an inner hood and an outer hood. The metal plate is fastened to the inner hood prior to assembly with the outer hood to provide a metal backing plate for attachment of the hood to a hinge. The metal plate is provided with at least one clearance hole which corresponds to at least one clearance hole formed in the inner hood. The fastening of the backing plate to the hood aligns the two sets of clearance holes to provide access for an attachment bolt to extend through the clearance holes and threadably engages a nut to attach the hood assembly to the hinge. The metal backing plate can include the nut aligned with the clearance holes and fixedly secured to the metal backing plate by projection welding if required.

Abstract: CARPET SEAMING APPARATUS AND METHOD            Abstract of the Disclosure A carpet seaming system and method include a seaming tape iron, a hot melt carpet seaming tape and a method of installation wherein seam peaking is minimized.  The seaming iron has a grooved base plate and connected liquid channels which accomplish seam welding of carpet backings at the seam.  The device feeds molten adhesive from the tape through the base plate of the iron up to an elevated location at or near a rear end of the iron, in a position to be picked up by and applied to opposed edges of the two carpet backings as the iron is moved along on the carpet seaming tape.  As the two carpet edges come together behind the iron, the backings are seam welded or seam sealed by the liquid adhesive in a butt joint, adding significant strength to the seam in the carpet.  In one embodiment, the carpet seaming iron further includes a tape dispenser connected to the iron, for storing and feeding a roll of hot melt seaming tape under the front of the iron's base plate as the iron advances along the tape.  The carpet seaming tape has a narrow hot melt adhesive strip, preferably less than two inches wide.  The carpet seaming tape may be used in conjunction with seam sealing, wherein hot melt adhesive is applied between the edges of the carpet backings to seal the seam between the two sections of carpet.  With the narrow tape and seam sealing, the assembled carpeting when stretched will not tend to peak significantly at the seam.

IPC: H03M7/42
Filed: 1992-10-28
Abstract: A process is disclosed for simultaneously transmitting signals from N-signal sources over a corresponding number of transmission channels. The individual signals are subdivided into blocks and the blocks are converted into spectral coefficients by transformation or filtering, and the latter are then subjected to a data reduction process. The invention is characterized in that the blocks belonging to the individual signals are subdivided into section. The momentary sections of all signals are processed together, the admissible disturbance is determined for each section by using a perception-specific model and the momentarily required total transmission capacity is calculated. The allocation of the maximum available transmission capacity for each individual signal is calculated from the total available transmission capacity and the total momentarily required transmission capacity. Each individual signal is coded and transmitted with the thus determined capacity.
