Inventor: FRANK WALTER C
IPC: C07C13/47
Filed: 1990-01-23
Abstract: TITLE Process for Preparing Polyalkyl Tetrahydronaphthalenes ABSTRACT A process is disclosed for the production of polyalkyl tetrahydronaphthalenes wherein a cyclialkylation reaction between an olefinic compound of the general formula                [VI] where R4, R5, R5 and R7 are independently defined and each is a substituent which does not interfere substantially with a Friedel-Crafts reaction, and a substituted benzene compound, is carried out in the presence of an alkyl halide or, in some embodiments, hydrogen halide, a Lewis acid, and, optionally, a phase transfer agent and a hydride abstracting reagent.  In some embodiments, the subject process is specifically carried out in the absence of elemental iodine.  The subject process, which may be practiced in an unhalogenated hydrocarbon solvent, produces the desired compounds in a surprisingly high yield, with a surprisingly high selectivity to the desired product, and at relatively high rate of reaction, using better, more convenient or less expensive process methodology than many processes known heretofore.
Patent CA-2008902-A1 (CA)
Title: Reconfigurable signal processor
IPC: G06F15/173
Filed: 1990-01-30
Abstract: RECONFIGURABLE SIGNAL PROCESSOR Abstract An interconnection scheme among the processing elements ("PEs") of a multiprocessor computing architecture realizes, through PE reconfiguration, bothfault tolerance and a wide variety of different processing topologies including binary trees and linear systolic arrays. By using a novel variant on a tree expansion scheme, the invention also allows for arbitrary up-sizing of the PE count to build virtually any size of tree network, with each size exhibiting the same high degree of fault tolerance and reconfigurability. The invention may be practiced with 4-port PEs arrayed in a module comprising a 4X4 board-mounted PE lattice. Each PE has four physical ports, which connect to the similar ports of its lattice neighbors. Each PE has an internal capability to be configured to route signals to or from ally of its neighbors. Thus, for tree topologies, any of the four neighbors of a given PE may be selected as the parent of the given PE; and any or all of the remaining three neighboring PEs may be selected as the child(ren) PEs. The PE ports are configured under the control of a remote Host, which establishes an initial desired PE topology. The operability of the PEs is tested, and information on faulty PEs or communications paths is used to enable or disable nodes as necessary by revising the PE port configurations. The nodes thus are reorganized and can run or continue running, on a degraded basis.

Title: Circuit for starting and operating fluorescent lamps
Inventor: SWANSON DAIL L
IPC: H05B41/36
Filed: 1990-02-09
Abstract: Abstract A circuit for starting and operating fluorescent lamps from an a-o low frequency power source includes a reactive ballast means connected to ballast the lamps and having a non-linear characteristic for producing a plurality of harmonics of the power source frequency, and a capacitor and a cathode heating transformer connected in series and connected to receive power from said ballast means and resonant in a frequency range encompassing a plurality of said harmonics.  This resonant voltage is applied across the lamps to aid the starting of their discharge and thereafter the lamps operate at the a-c power source frequency.  The aforesaid resonance frequency range preferably is broad enough to encompass several harmonics of the power source frequency, for example the third through the ninth harmonics (180 to 540 Hz for for a source frequency of 80 Hz.). Preferably a switch is connected in series with the capacitor and cathode heating transformer for opening the cathode heating circuit when the lamps are operating.  This switch may be a bidirectional diode or equivalent voltage sensitive solid state switch, which switches on and off during each half cycle of the lamp starting time period and thus contributes to the harmonic content of the starting voltage waveform.

Title: Method and instruments for acl reconstruction
Inventor: ROSENBERG THOMAS D
IPC: A61B17/16
Filed: 1991-01-29
Abstract: METHOD AND INSTRUMENTS FOR ACL RECONSTRUCTION    ABSTRACT           An improved method of reconstructing a torn anterior cruciate ligament (ACL) is disclosed.  Unique instruments and systems for use with the method are also   disclosed.    The   knee   joint   is   inspected arthroscopically to confirm the rupture and possibly take care of other defects.   The patellar tendon or semitendinosus tendon is harvested from the patient for the graft (if  either is  going to be used  for the reconstruction), or another ACL substitute is obtained. The graft is prepared for implanting.  Notchplasty is generally performed to expand the intercondylar notch. The tibial attachment  site of the ACL is determined and a tibial tunnel is drilled over a K-wire from the front face of the tibia to the attachment site using a drill guide system. Preferably, the tibial tunnel starts at a point 20-25 mm below the knee joint.  An optimal site for drilling the femoral tunnel is determined through use of a suture anchor and isometer.  The suture anchor is a threaded peg which is positioned by a hand-held cannulated driver.  A pilot hole is formed preferably with a unique K-wire device having means thereon for limiting the depth of the hole.   Once the isometric point has been determined,  a closed-end tunnel  (or "socket") is drilled into the femur at that point.  The hole is drilled using a new drill bit having a small shank,  an  abbreviated  drilling  head,  and  a  smooth transition portion between the shank and head;  this drill bit prevents damage to the posterior cruciate ligament.  The graft is implanted through the osseous tunnel with one end being secured in the closed-end femoral tunnel and the other end to the front of the tibia  adjacent to the tibial  tunnel.  Semitendinosus tendon grafts are prepared in bundles with elongated sutures stitched at the ends. A suture passing channel is formed through the femur from the closed-end femoral tunnel and the graft sutures are passed through it and connected to the lateral face of the femur by a button. The graft sutures are affixed at the other end of the graft  to  a  post  or  screw  secured  in  the  tibia. Patellar tendons can be affixed at one end  in the closed-end femoral tunnel with an interference screw, or,  alternately,  sutures  passed  through  a  passing channel and affixed to a button on the femur.   The other end of the patellar tendon grafts are secured by being stapled or otherwise  securely affixed to  the tibia.
