Title: Method for subcutaneous suprafascial pedicular internal fixation
Inventor: MATHEWS HALLETT H
IPC: A61B17/70
Filed: 1992-12-01
Abstract: A method for internal fixation of vertebra (10) of the spine to facilitate graft fusion includes steps for excising the nucleus of an affected disc, preparing a bone graft, instrumenting the vertebrae for fixation, and introducing the bone graft into the resected nuclear space. Disc resection is conducted through two portals (26a and 26b) through the annulus (15), with one portal supporting resection instruments and the other supporting a viewing device. The fixation hardware includes bone screws (30), fixation plates (40), engagement nuts (42), and linking members (44). In an important aspect of the method, the fixation plates, engagement nuts and linking members are supported suprafascially but subcutaneously so that the fascia (22) and muscle tissue (23) are not damaged. The bone screw (30) is configured to support the fixation hardware above the fascia (22). In a further aspect of the invention, a three component dilator system (50) is provided for use during the bone screw implantation steps of the method.

IPC: G01N21/15
Filed: 1993-06-01
Abstract: PCT No. PCT/CH93/00141 Sec. 371 Date Feb. 1, 1994 Sec. 102(e) Date Feb. 1, 1994 PCT Filed Jun. 1, 1993 PCT Pub. No. WO93/24824 PCT Pub. Date Dec. 9, 1993.In a method for measuring solid concentrations in liquids, the light from two differently modulated sources (Q1, Q2) directed on the liquid is measured at the same time and processed in a combined multi-beam measuring process consisting of a 90 DEG  light scatter (Q1, P, D4; Q2, P, D3) and back-scatter process (Q1, P1, D1; Q2, P3, D2) and the solid concentration is found therefrom. The process is suitable for the simultaneous measurement of both extremely low and extremely high solid concentrations by using a 90 DEG  light scatter process for low concentrations and a back scatter process for high concentrations. The multi-beam process which is based on two measurements through exactly the same window areas makes it possible effectively to compensate for undesired soiling of the window areas. Mechanical devices for cleaning the window areas and to eliminate interfering light scatter are proposed.

Title: Hardness suppression in urea solutions
Inventor: DUBIN LEONARD
IPC: C05G5/23
Filed: 1992-09-23
Abstract: The tendency of aqueous solutions of area and other NH-containing compositions to force instability of hardness factors has been found to be detrimental to processes and apparatus employing them.  The reliability of these processes and apparatus is improved by the inclusion of hardness-suppressing compositions, which preferably include both a water-soluble polymer and a phosphonate. In particular, agricultural and NO X-reducing applications are, improved, especially for solutions containing urea hydrolysis products and the salts of them.
Patent CA-2121495-A1 (CA)
Title: Laser Bonding of Angioplasty Balloon Catheters
Inventor: FORMAN MICHAEL R
IPC: A61M25/16
Filed: 1992-09-04
Abstract: A process for assembling a balloon catheter (16, 60) involves selectively concentrating laser energy along an annular fusion bond site (72) at contiguous surface portions (74, 76) of a length of catheter tubing (62) and a shaft or neck portion (68) of a dilatation balloon (66). The laser energy wavelength, and the polymeric materials of the balloon and catheter, are matched for high absorption of the laser energy to minimize conductive heat transfer in axial directions away from the bond site. This minimizes crystallization and stiffening in regions near the bond site, permitting fusion bonds to be located close to the proximal (24) and distal (26, 70) cones of the dilatation balloon (20, 66) while preserving the soft, pliant quality of the cones. The disclosure further is directed to an embodiment of a balloon  catheter assembled according to the process.

Title: Electromagenetic device and method for boundary layer control
Inventor: NOSENCHUCK DANIEL M
IPC: B63B1/34
Filed: 1993-06-25
Abstract: The boundary layer of a fluid travelling in a mean-flow direction relative to a surface (104) of a wall of a body is controlled by generating in a near-wall region of the flow a magnetic field B  B7 having flux lines (103) parallel to the surface of the wall and an electric current density J B7 (109) traversing the magnetic flux lines in the fluid. An electrolyte (130) or other conductivity-enhancing material is introduced into the flow to provide an electrical conductivity gradient in the near-wall region. The magnetic field B B7 (103) and the electric current density J B7 (109) create in the fluid a force J B7 x B B7 (131) having a component normal to the surface (104) of the wall that because of the increased conductivity gradient near the surface can stabilize or destabilize flow in the boundary layer. Numerous aspects of the fluid flow and its interaction with the body can thus be controlled.

Abstract: An electronic security system includes an electronic lock mechanism (104) and an electronic key (101), each of which is provided with a microprocessor controller and a memory storing data including an ID code and encryption key codes. The lock microprocessor may either change ID codes stored in it's memory or encrypt a seed number to be used for determining access to the lock.

The electronic lock operates a solenoid (1624) which retracts a bolt-blocking mechanism that prevents the unlocking of the bolt even when a key having the correct mechanical key cuts is inserted into the lock. Power for operating the electronic lock as well as the solenoid is provided by a power supply within the key. In a preferred embodiment the key unit is composed of a handheld computer witha separate internal circuit board which stores key code information and performs encryption/decryption functions. A novel electronic T-lock (1340) assembly is also provided for use with vending machines and the like.

Patent CA-2161855-A1 (CA)
Inventor: GRIESEMER PATRICK J
IPC: G01V8/12
Filed: 1995-10-31
Abstract: Obstacles are protected against collision in aisles adjacent mobile storage units with an IR transmitter mounted in spaced apart relation to an IR  receiver  on  a  unit.    For  initializing  and calibrating the system a microcomputer controls the transmitter to emit IR pulses of increasing width at a uniform repetition rate.  If there is no defect in the  system  the  receiver  responds  with  output electric pulses after the IR pulse width is reached that has the minimum integrated energy to exceed the input signal threshold of the receiver.  The minimum energy pulse width is stored in the microcomputer and the system switches to a run mode allowing storage units to move when commanded.  The computer responds to the absence of returned pulses from the receiver by inhibiting the system so the mobile unit will not run.   If returned pulses are not in the proper phase relationship the system goes into a diagnostic  mode  wherein the  interval  between transmitted IR pulses is reduced in increments for reasons including determining if there may only be temporary ambient IR interference.  If the problem does not clear up by the time the  interval  is reduced to one-half normal interval the system locks out.
