Title: Device for checking the tension of a suture during a surgical procedure
Inventor: KABBARA JAMIL
IPC: A61B19/00
Filed: 1989-12-22
Abstract: ABSTRACT    The invention concerns a device to check the tension of a suture during a surgical operation.    A forceps (2, 2') comprises two jaws which can pivot on one another, around a axis (Y-Y) to tighten a suture, and it can pivot around another axis, almost perpendicular to the first.   A spring (15), whose force can be adjusted, main-tains it in one position (2) in which in can be used as a conventional forceps, but if the pulling force applied to the suture exceeds a predetermined limit in a defined direc-tion  (21),  the  forceps  pivots,  and  this  visualizes  the excess.    According to another design, a piezoelectric element or a stress gauge is used to emit an information signal when the selected limit tension is exceeded.

IPC: E21B49/08
Filed: 1989-12-29
Abstract: A delayed opening fluid sampling tool comprises a body having three chambers and a port defined therein.  The tool also comprises a metering device which is disposed in the body between two of the chambers, one of which chambers is for holding a metering fluid and the other of which is for receiving fluid which is transferred through the metering device.  The tool further comprises a valve which is dis-posed in the body between the port and the remaining cham-ber, which remaining chamber is for receiving a well fluid sample.  The valve is moved relative to the body in response to pressure acting on the valve through the port.  Only after a predetermined time delay after the pressure begins moving the valve is the valve positioned to communicate the port with the sample-receiving chamber.

Paulsen ABSTRACT OF THE DISCLOSURE     A series of rectangular casing blocks or slices includes various functional electronic modules and typically provide a power slice, a data storage slice, a demountable portable keyboard slice, a demountable communication slice and a demountable visual display slice.  The slices are assembled and latched in top-to-bottom attachment or in front-to-back attachment so that a stack of four or more slices is formed and the slices are easily removed for off-site use.  Each slice has an internal mounting frame to which is attached plastic edge connection strips having interconnection grooves and tongues at opposed ends.  The tongues and grooves are slid together and a latch bail provided for latching together strips abutting in a front-to-back attachment.  When strips and the frames of the slices to which the strips are to be attached bottom-to-top another series of interfitting tongues and grooves on the ends of the respective strips are slid into aligned abutment and a latch plate pivoted inwardly to lock the strips and slices together.  The latch plate also covers and prevents inadvertent disassembly of the bail.

Abstract: ABSTRACT OF THE DISCLOSURE      In a method for laminating a plastic web onto a plastic substrate, the web is moved past an adhesive coating station where one surface is coated with a mixture made of solvent and resin particles.  The substrate is moved past a cleaning station, where a surface is also coated with a mixture made of solvent and resin.  After the web and substrate pass through drying chambers, the coated surfaces are pressed together with rollers and heat is applied.  The method is particularly suitable for laminating strips bearing a wood-grain pattern onto extruded thermoplastic members which are thereafter cut into segments for use in making prefabricated window systems.

Filed: 1990-05-29
Abstract: Disclosed is an outside rear-view for a vehicle which has a pedestal to be mounted to a body of the vehicle and a mirror housing held to the pedestal. An electric motor is provided for tilting the mirror housing relative to the pedestal. The electric motor is mounted to the inner surface of an assembly plate bordering the pedestal towards the body, and the drive shaft of the electric motor is linked preferably through a transmission gear and/or a clutch and through a cam to a rigid transmission member coupled to the mirror housing. Alternatively, the drive motor may be mounted within the interior of the mirror housing, the transmission member coupled to the cam of the driving motor then may be coupled to the pedestal. Thereby the advantages are obtained that the electric driving motor does not project outwardly from the normal outer conture of an outside rear-view mirror and may be utilized for any modes of mounting of the mirror housing to the pedestal.

Patent CA-2038440-A1 (CA)
Title: Active muffler transducer arrangement
Inventor: GEDDES EARL R
IPC: F01N1/06
Filed: 1991-03-18
Abstract: Abstract An active muffler for use in motor vehicles comprises a sensor, an electronic control responsive to the signal generated by the sensor for producing a drive signal delivered to a transducer which emits cancellation pulses phased 180° from the sound pres-sure pulses passing through a conduit, where both front and rear sides of the transducer are acoustical-ly coupled to the conduit to improve the efficiency of the transducer operation.  Preferably, the acoustic coupling comprises an enclosed chamber including a port for communicating with the conduit which can be tuned to resonate at predetermined frequencies.  When both sides of the transducer are so coupled to the conduit, the transducer has increased efficiency over a broad band of frequencies, and the frequency band can be broadened at the low end as required to accom-modate the frequencies generated by a source of noise. The transducer mounting arrangement according to the present invention is particularly suitable for use in adapting noise cancellation techniques to replace passive mufflers on motor vehicles.
