Abstract: ABSTRACT OF THE DISCLOSURE         An insertable pickup probe and interface network for magnetic resonance imaging and spectroscopy.  The pickup probe in the preferred embodiment is for use in imaging the male prostate and comprises an elongated shaft supporting a patient interface balloon at its distal end which contains a RF receiving coil.  The interface balloon comprises an inflatable inner balloon enclosed by a flexible outer balloon.   The receiving coil is positioned between the inner and outer balloons and placed intimately adjacent the region of interest by inflating the inner balloon to expand outwardly  against  the  outer  balloon.    In  addition,  a  non-stretchable planar material is provided on the surface on the inner balloon adjacent the receiving coil for ensuring that the receiving coil is placed adjacent the region of interest. The inner balloon is  inflated by an  inflator cuff  connected to the  shaft  and communicated to the inner balloon by a first lumen in the shaft.          The receiving coil is electrically connected to an interconnecting cable which is connected to the proximal end of the shaft and communicated to the receiving coil by a second lumen in the shaft.

Title: A key for a printed circuit board
Inventor: ROTHLIN PETER
IPC: H01H13/48
Filed: 1990-04-09
Abstract: ABSTRACT OF THE DISCLOSURE            A key for printed circuit boards comprises an electrically conductive snap disk embedded in a recess in a spacer layer between a cover foil and a board coated with printed conductors. The key is used as an opener key with a pressing point, to which end, the snap disc has contact tabs and, offset therefrom tension tabs.  The tension tabs are fixed to the board with biasing in order to produce the necessary contact pressure in the unactuated state.  Each contact tabs has a shoulder which is curved towards the board and which upon actuation of the snap disk bears on the board and, with increasing actuating force, reduces the contact force (Fc) of the contact tab until the contact surface disengages.  Disengagement of the contact surfaces and the passage through the pressure point or peak value for the actuating force (Fa) occurs at the same deformation travel (d) of the snap disk.

Abstract: HIGH-SPEED TIME-DIVISION SWITCHING SYSTEM Abstract A non-blocking broadband broadcast time-division switching system (10) comprises a time-slot replication stage (12) followed by a conventional TMS stage (11). The replication stage replaces the TSI stage of conventional switching systems. Time division multiplexed links (16) are connected to inputs of the system. Each input link is connected to the input of a different replicator (14). Each replicator has as many outputs as there are timeslots (202) in a frame (201) on an input link. Replicators' outputs are connected each to a different input of the TMS stage. In one embodiment, a replicator generates each time slot of a received frame at a different output and replicates the individual time slot at the individual output during each time-slot interval of a frame interval. In another embodiment, a replicator generates each time slot of a received frame at a different time at each output, thus generating a delayed replica of the received frame at the outputs. In either embodiment, during each time-slot interval, each replicator transmits a frame of different received time slots to the TMS stage.

Patent CA-2042002-A1 (CA)
Inventor: KISH JULES G
IPC: F16H55/14
Filed: 1991-05-07
Abstract: ABSTRACT An elastomeric torsional isolator comprises one or more elastomer layers disposed between a spur gear, having a pair of sloped surfaces, and a pair of rims having corresponding surfaces.  The rims are attached to a flange extending from a shaft which has pinions for engaging a driven gear.  By pre-loading the elastomer layers, the spur gear is frictionally connected to the flange and shaft, rather that mechanically engaged.  The preloaded elastomer layers act as an elastomeric torsional isolator which accommodates variations in mechanical tolerances to balance the torque loading in a split torque drive system.  Using elastomer layers for balancing the torque loading between a pair of torque splitting gear assemblies reduces the number of bearings required, increasing reliability and reducing part complexity.
