Title: A flue for an ultrasonic surgical handpiece
Inventor: BROADWIN ALAN
IPC: A61B17/32
Filed: 1996-07-29
Granted: 1998-05-07
Abstract: An ultrasonic oscillator drives a tool at a set frequency. An amplitude control runs the oscillator to set the vibration level. A frequency regulator joins the amplitude and the oscillator. A control feedback loop, in the frequency regulator, keeps handpiece linear dynamics. An operational transconductance amplifier, in the oscillator, governs gain of the loop. A circuit connects to the control to retard the rate of current application over time to the amplifier. The circuit has switching to either retard the rate or reset for start up. The amplifier is a current output device with current directly proportional to the bias current and input voltage with bias as gain change for the loop. The circuit limits the bias to the amplifier to modify frequency response and output current. A capacitor delays application of the bias to the amplifier. Replaceable tools of various lengths or shapes positioned along an axis vibrate for surgery at the frequency and a wave length. Tools longer than one wavelength and of configurations tuned to oscillate around the frequency resonate as a function of their material, length and configuration. A flue surrounds the tool and has a hollow elongate semi rigid central body about an axis with a funnel, at one end thereof and a nozzle, at the other to direct annular irrigant/coolant flow therethrough. The funnel and nozzle are resilient. Reinforcing ridges, inside the nozzle, act to maintain concentricity between the flue and nozzle tip and channel irrigant thereabout.

Title: System for geothermal production of electricity
Inventor: SHNELL JAMES H
IPC: F24J3/08
Filed: 1996-06-07
Granted: 1999-01-07
Abstract: A system for the generation of electricity from geothermal energy that is less expensive, more efficient, and avoids dealing with undesirable byproducts, is disclosed. The system of the present invention relies on using endothermic reactions at the bottom of a well to capture and store the geothermal heat, and exothermic reactions at the top of the well to release the heat stored within the products of the endothermic reactions. In the preferred embodiment, the endothermic reaction is the dehydrogenation of ethanol. To induce the endothermic reaction as well as to harvest and separate the resulting products, a catalytic device is used where each type of product selectively diffuses into its individual conduit. The endothermic products undergo the exothermic reaction in a combustion turbine, and the products of the exothermic reaction are immediately condensed in a condenser. In the preferred embodiment the condenser condenses ethanol vapor into a liquid to be returned down the well, thus creating a closed system.

Patent AU-685441-B2 (AU)
Title: Tissue equivalents
Inventor: DAVIES ALBAN
IPC: A61L27/24
Filed: 1994-03-29
Granted: 1998-01-22
Abstract: A method of forming a tissue equivalent is described. A length of polyester tube is threaded over a mandrel (H) and attached at either end by clips at A and D. A block (F) is then screwed into place. The polyester is then pre-soaked by injecting through Tap (2) an acidified collagen solution for approximately one hour. After a suitable period of time the excess solution is aspirated off. Following this stage, a second, alkaline solution is injected into the apparatus which contains smooth muscle cells (SMC). Thus, neutralisation of the collagen impregnated within the fabric of the tube occurs leading to spontaneous fibrillogenesis within the interstices of the cloth, eliminating the risk of delamination. The apparatus is then incubated. The collagen contracts down onto the fabric tube and the cell-impregnated gel becomes incorporated into the presoaked collagen. The pre-impregnated collagen and the collagen provided in the aqueous mixture contract down as one into a coherent whole with the SMC. The tissue equivalent is then lined with endothelial cells and the apparatus again incubated and fed at increasing intraluminal pressures applied either statically or dynamically. This is believed to cause the vessel to become preconditioned to the pressure it will work under as an implant. This allows organization of the basement membrane which in turn promotes EC attachment and theoretically prevents smooth muscle cell hyperplasia.
