Title: An ultrasonic surgical handpiece and an energy initiator to maintain the vibration and linear dynamics
Inventor: BROADWIN ALAN
IPC: A61B17/22
Filed: 1993-09-17
Granted: 1996-09-26
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: Bicycle frame with internal brake cable
Inventor: DIEKMAN ROBERT LEROY
IPC: B62K3/02
Filed: 1985-11-27
Granted: 1987-11-26
Abstract: The invention relates to a bicycle frame of the type having a head tube (12), a seat bracket (14) and a bottom bracket (16), each having hollow lugs (24) extending therefrom and joined together by cylindrical tubes (18, 20, 22) extending over and attached to the lugs, having an internal cable system in which the top lugs of the head tube and seat bracket each have a cable outlet (50, 62), and a cable (18), such as a brake cable, is threaded through the cable outlets and along the tube joining the head tube and seat bracket. The cable outlet of the head tube is positioned immediately adjacent to the open, tubular segment (30) of the head tube. Positioning the outlets on the lugs preserves the structural integrity of the top tube and facilitates replacement of the cable. Replacement is effected by pushing the cable through the cable outlet of the seat bracket, along the tube to the head tube, then out through the head tube cable outlet. The cable tip may be guided through the head tube cable outlet by inserting one's index finger through the head tube opening to deflect the cable tip toward the head tube cable outlet.

Title: Flow through chemical indicator for measurement of biocidal agents
Inventor: SCHINDLEY BRIAN E
IPC: G01N31/22
Filed: 2000-05-19
Granted: 2003-07-31
Abstract: A single-use cartridge C contains a dose of a concentrated decontaminant for providing a decontaminant solution upon mixing with water. The cartridge is inserted into the well (16) of a decontamination system (A). Fresh water and then the decontaminant solution are recirculated through the well during a decontamination cycle. The cartridge includes a porous region (42), through which the decontaminant solution flows. Impregnated in the porous region is a chemical indicator (44), such as crystal violet, which gradually changes color on exposure to the decontaminant. The indicator provides a semi-quantitative indication of the integrated level of the decontaminant in the solution over time for determining whether an acceptable level of the decontaminant was present for decontamination. A preferred embodiment of the cartridge C includes nested inner and outer water-penetrable cups (50,150,70,170) for holding first and second reagents. The two cups are sealed together adjacent upper open ends (56,92,156,192). A porous top cover (94, 194) is sealed to the inner cup adjacent the inner cup open end (92, 192) to complete the cartridge. The two reagents react with water flowing through the cartridge to form the decontaminant solution. The chemical indicator is printed on the top cover so that it is exposed to the decontaminant solution as it is recirculated through the cartridge.

Title: Coatings for production of hyperpolarized noble gases
Inventor: DRIEHUYS BASTIAAN
IPC: G01N24/12
Filed: 1996-06-07
Granted: 1998-08-06
Abstract: The invention provides a method of inhibiting surface-induced nuclear spin relaxation and surface trapping of a hyperpolarized noble gas, most preferably 129Xe, by polymer-coated surfaces. The method includes inhibiting the amount of interaction of the noble gas with a polymeric coating on the surface of apparatus which contacts the noble gas. Preferably, the method includes inhibiting noble gas nuclear spin relaxation by replacing at least some of the protons in the polymer with substituents which have non-zero nuclear spin and/or reduced polymer permeability. A preferred substituent having non-zero spin is deuterium. A preferred modification which reduces permeability includes introducing into the polymer a substituent such as a halogen, more preferably fluorine. The method also provides containers having surfaces which have been coated with a polymer which inhibits noble gas trapping and nuclear spin relaxation. Furthermore, the invention provides methods for enhancing the production and storage of a hyperpolarized noble gas by decreasing the relaxation of nuclear spin and limiting the trapping of the noble gas in a polymeric coating of apparatus containing the noble gas.

Title: Handwritten symbol recognition - optical scanner with intermediate memory compensates non-uniform degree of blackness along symbol
IPC: G06V30/168
Filed: 1969-08-26
Abstract: The character recognition system is for written symbols using electro-optical scanning of the degree of blackness of the symbol along a line for retaining in an intermediate memory matrix before passing to the electronic logic recognition circuits.

Title: Production of two core coiled stretching lead - involves twisting one core round other core before applying protective sleeving
IPC: H01B7/06
Filed: 1969-12-23
Abstract: The application is mainly to coiled leads for domestic appliances, and may be used for connecting telephone hand sets to the body of the instrument. The cable comprises two separate cores with conductors covered with insulation. One core is wound round the other, which is straight, with a pitch equal to that finally required. The outer sheath is then applied which holds the cores together. The sheathed cable is then wound round a mandrel whilst at the same time twisting the conductors relative to each other so that one lies radially over the other. This form of construction imparts coil spring qualities to the cable without the need for inserting a separate spring element.

An AND-gate (GU1) is connected by its two inputs to the flip-flop output and to one or more of the input trains whose pulses to not normally (i.e. no fault) coincide with the output signal from the flip-flop.
