Title: Method and apparatus for measurement and imaging of tissue compressibility or compliance
Inventor: OPHIR JONATHAN
IPC: G01N29/07
Filed: 1990-11-16
Granted: 2002-05-28
Abstract: An improved ultrasonic pulse-echo method and apparatus that has particular application in making precision measurements of compressibility in any backscattering material, in particular organic tissue, is disclosed. The method employs a standard transducer or transducer containing device which is translated transaxially, thereby compressing or displacing a proximal region of a target body in small known increments. At each increment, a pulse is emitted and an echo sequence (A-line) is detected from regions within the target along the sonic travel path or beam of the transducer. Resulting time shifts in echo segments corresponding to features in the target provide relative and quantitative information concerning compressibility of the target.

Abstract: A power tool such as a hand held vacuum cleaner (10, Fig. 1) has a housing (12) and nozzle (22). The housing mounts a motor and switch carrier (20) which mounts a motor (30) driving a tool (fan) (24) and a switch (40).   A battery pack (50) powers the motor (30).      The electrical arrangements comprise conductors (1-6, Fig. 2) punched from a single strip and fixed in guides (44) formed on the carrier. Terminals of the motor and battery are pressed through slits (46, 48) in some conductors. The conductors pass-into tracks (100, Fig. 5) formed on a tray (54) of the switch. A mask (78) is positioned on the tray to expose the conductors in discrete switch positions (A, B, C) of slide connectors (68) mounted in a switch slide (64) slidably mounted on the tray. In different switch positions different contacts are made, the arrangement allowing different models of the same tool to be constructed with minimum adjustment of components or assembly routines.

Title: Desalting adjunct chemistry
Inventor: STEPHENSON WILLIAM K
IPC: C10G33/04
Filed: 1992-08-11
Granted: 2004-11-02
Abstract: Improved performance in the phase separation of aqueous brines from hydrocarbons within an electrostatic desalter operation is obtained by the addition to the crude oil emulsions enterinq the desalter of an effective asphaltene dispersing amount of an alkyl phenol-formaldehyde liquid resin polymer, optionally in the presence of a lipophilic/hydrophilic vinylic polymer.      The preferred resin is a nonyl phenol-formaldehyde resin having a molecular weight of from 1,000 - 20,000, and the preferred vinylic polymer is a copolymer of lauryl (meth)acrylate and hydroxyethyl (meth)acrylate.      Best results from the electrostatic desalter are obtained when also using a demulsifier chemical treatment along with the asphaltene dispersing treatments. Desalter efficiency is increased and desalter brine effluent quality is greatly increased.

Title: Grain processing apparatus
Inventor: GREER DAVID G
IPC: B02B1/06
Filed: 1992-12-03
Granted: 2003-10-28
Abstract: An apparatus and method of processing grain by raising the moisture content of the grain relative to a target level.        As the grain is moved through a processing area, the moisture content and the mass flow of the grain are measured. Each measurement is converted to an electronic signal anel the signals are fed to a programmable controller which blends the two signals arid produces a single output control signal that is fed to a proportional control valve, The control valve acts responsive to the control signal to adjust the amount of moisture added to the grain at a wetting station. An additive such as a surfactant can be metered into the water supply.

Abstract: A coated porous metal panel includes a first outer surface on one side of the panel, a second outer surface on the other side of the panel, a plurality of laterally offset discharge and inlet pores in respective ones of the first and the second outer surfaces, an internal chamber in the panel communicating with each of the inlet and discharge pores  o that tortuous gas flow path  are defined through the porous metal panel, and a shield lamina mechanically clamped against the second outer surface. The shield lamina has shield pores aligned with the inlet pores to permit gas flow into the inlet pores.  A plurality of extraction passages are formed in the panel between the internal chamber and the second outer surface and directly behind each of the discharge pores.  When the coating material is sprayed on the first outer surface with the shield lamina not attached to the panel, surplus coating entering the discharge pores passes through the extraction passages for collection behind the panel.  The shield lamina blocks the extraction passages to prevent gas flow into the extraction passages and short circuiting of the tortuous gas flow paths in the porous metal panel.

Abstract: A unique financial process to create a banking product which would replace transactions made by: 1. money  2. cheques  3. certified cheques  4.  money orders  5. visa*  6. visa cheques  7.  line of credit cheques  8. bank drafts  9. travellers cheques  10. client cards used for banking machines.    The proposed financial product called, "XYZ (company name) Guarantee Money" will have the appearance of money and not a cheque or money order and it will state in bold letters that the maximum that shows on the bill is guaranteed by the Bank or Trust company or Credit Union or other qualified institution which issued the bill.          The proposed financial product will be created by a bank or other qualified financial institution in a similar fashion as a money order, or certified cheque, or a travellers cheque, or bank draft is created when a customer of a bank pays money for the money order or certified cheque or travellers cheque or bank draft.  In this invention the customer will pay to a Bank the maximum that will show on the Guaranteed Money issued.  The guarantee money bill though will be different than the four products mentioned in this paragraph as it will have the space for how much it will be used for, blank, and it will only be filled out at the time of purchase, with the exact amount.  The owner of the Guarantee Money will be able to purchase products or services to the maximum that will show on the bill.          For example, for a Guarantee Money issued by the Bank for $20.00 dollars maximum, the owner of the bill will purchase a product for say $16.00 dollars and print the words sixteen dollars and the number $16.00, then insert the name of the vendor on the bill and sign it just like in the case of a cheque.  When the vendor deposits the bill in his Bank he will be credited only $16.00 dollars and the purchaser will be credited the remaining $4.00 dollars. If a purchase of $20.00 dollars is made then the vendor will be credited for $20.00 dollars and the purchaser zero since all the money is spent. By using Guarantee Money people will not have to look for change in their pockets and they will not have to wait for change.

Granted: 1998-04-14
Abstract: A computer system having four states of power management:  a normal operating state, a standby state, a suspend state, and an off state.  The standby state is characterized by devices, such as a video controller and a hard drive, being placed into a low-power mode transparent to the operating system and the applications executing on the computer system.  The suspend state is characterized by executing code being interrupted and the state of the computer system being saved to a file on the hard drive in such a manner that system power may be removed after the state of the computer system is saved to the hard drive.  Later, after system power is restored, the state of the computer system is resumed by reading from the hard drive and loading it in such a manner that the operating system and application programs are not adversely affected.  The normal operating state and the off state correspond to the typical on and off states of more conventional computer systems.   The suspend/resume/standby feature is implemented at a low cost using many standard components.

Les hydrocarbures se transforment en eau, en dioxyde de carbone et en faibles quantités de méthane. En pratique, la propagation de la végétation aquatique qui dépend des espèces de phosphore et des espèces de soufre est inhibée par l'élimination de ces mêmes espèces du milieu. Les métaux lourds sont inactivés.
