Title: Method of and apparatus for controlling turbulence in boundary layer and other wall-bounded fluid flow fields
Inventor: SIROVICH LAWRENCE
IPC: F15D1/06
Filed: 1996-02-09
Abstract: Turbulence is controlled in boundary layer or wall-bounded fluid flow fields having a turbulent wall region characterized by a system of roll pairs extending in the direction of flow, and obliquely propagating structures interacting with the system of roll pairs, by locally introducing into the turbulent wall region two separate disturbances that are effective to produce, in a local region, a composite disturbance field that is strongly coupled to and modifies the obliquely propagating structures in a manner that increases or decreases the interaction of the propagating structures with the system of roll pairs thereby locally increasing or decreasing the turbulence in the flow field.  One of the disturbances may result from the interaction of the fluid with a linear strip, or an array of strips, of delta-shaped protrusions positioned spanwise on the wall (i.e., transverse to the flow direction); and the second disturbance may result from injecting sonic energy into the local region.  Furthermore, a linear strip or an array of airfoil shaped protrusions can be used for producing a pair of counter rotating rolls for controlling turbulence in the boundary layer.

Patent CA-2180461-A1 (CA)
Title: Attachment Means
Inventor: GOOVAARD JAN
IPC: B41N6/02
Filed: 1995-01-13
Abstract: Attachment means for attaching a flexographic printing form, particularly a printing form of photopolymeric material, on a plate cylinder, is provided with a flexible supporting layer and a photopolymeric layer supported by the supporting layer being fully exposed.  In order to obtain a particularly effective attachment means the adherent characteristics of a photopolymeric layer are advantageously utilized.          Experiments have shown that these adherent characteristics are also maintained in case of intensive use during at least 8 to 12 months.  Moreover, on the one hand a good attachment of the printing form on the plate cylinder is achieved, whereas on the other hand the printing form can relatively easily be removed from the adherent photopolymeric layer and no residual photopolymeric material remains on the printing form.  In this way a long lifetime of the attachment means applied on the plate cylinder is achieved, while on the other hand the printing form needs no longer undergo any cleansing treatment.  Damaging of the printing form by removal is excluded as well so that the printing form is more times available for repeat order without any problem.

Abstract: Article conveyor apparatus and method are disclosed having fluid containment, and particularly for conveying of articles such as cans having an oily liquid thereon when transported from a processing or forming station.  The articles are mass transported along a predetermined path that is closed to the atmosphere except for infeed and discharge of articles, with the articles being transported by engagement with a moving belt having openings therein.          The inlet of a chamber, otherwise closed to the atmosphere and having negative fluid pressure maintained therein during normal operation, is positioned adjacent to the belt so that the negative pressure maintains articles in contact with the belt during transport along the predetermined path regardless of path orientation and also draws fluid from the transported articles and belt into the chamber through the openings in the belt and the chamber inlet.  The fluid, such as an air-liquid mixture that includes liquid not then gravity separated in the chamber from the air, is discharged from the chamber to a pressure source that also provides positive pressure through a conduit to a perforated top plate positioned at the predetermined path.

Inventor: KEEFE DOUGLAS H
IPC: A61B5/12
Filed: 1995-06-06
Abstract: A system and method of measuring the linear and nonlinear response of an unknown acoustic termination uses a small probe assembly containing a sound source and microphone to determine the reflection function of the unknown acoustic termination. The probe assembly is used with a calibration tube to calculate an electrical signal that will provide a desired acoustic stimulus signal to the acoustic termination. The calibration tube is also used to characterize the signal processing properties of the sound source and microphone, as well as other associated signal processing circuits such as amplifiers, filters, and the like. The calibrated system is subsequently coupled to the unknown acoustic termination to deliver the acoustic stimulus signal. The reflection function is indicative of the power transferred to the unknown acoustic termination. The measurement of the linear transfer characteristic is applicable to any unknown acoustic termination such as a musical instrument or the auditory system. The probe assembly is sized to be positioned directly within the outer portion of the ear and measure the linear characteristics of the ear. The system is further able to measure the nonlinear transfer characteristics of the ear by measuring the linear response at multiple levels of the acoustic stimulus. The system is particularly useful in testing the response of the middle ear and inner ear of humans or other animals.

Patent CA-2203842-A1 (CA)
Inventor: KHADIM NEIL M
IPC: B60K15/03
Filed: 1997-04-28
Abstract: An instant-on valve assembly with manual override is designed to be connected to a tank containing high pressure gaseous fuel.  The valve assembly and manual override allows the tank to be alternately closed off, vented or allows the gas in the tank to bypass the instant-on valve.  The instant-on valve assembly can be repaired or replaced without venting the tank.  The instant-on valve assembly has a main valve and a bleed valve.  The main valve has a secondary plunger that opens and closes a main orifice.  The bleed valve has a bleed valve stem that opens and closes a bleed orifice.  The main valve is slidably mounted within a housing and has a chamber at one end and a zone at another end.  Both the zone and the chamber have access to high pressure gaseous fuel within the tank.  High pressure gaseous fluid within the zone can be drained when the bleed valve stem is fully open.  The bleed valve stem is connected to a solenoid and opens upon activation of the solenoid. When the pressure within the zone is sufficiently reduced, the pressure within the chamber will cause the main valve to open by sliding into the zone.  A spring moves the main valve towards a closed position when the solenoid is deactivated.  Since the volume of the zone is relatively small, the main valve opens within one second after the solenoid is activated.

IPC: B09B3/00
Filed: 1997-05-23
Abstract: A method for minimizing waste volumes from the demolition of  radiologically  and/or  chemically  contaminated  concrete facilities  by  using  engineering  techniques  to  separate contaminated from uncontaminated fractions and/or by reusing the contaminated  concrete  for  manufacture  of  waste  storage  or disposal containers.   Explosive demolition is used to either selectively remove contaminated surface layers of concrete from underlying uncontaminated concrete (where the contamination is confined to the surface layers), or, where the contamination is throughout the concrete, to reduce contaminated concrete into pieces of an appropriate size for use as manufacturing aggregate.          The balance of the concrete structure can alternatively be demolished using standard techniques if underlying concrete is clean, and the resulting rubble free released for recycle or disposal.   When required,  the concrete pieces are processed through a concrete crusher until the appropriate aggregate size is achieved.  The recycled and previously regulated aggregate is then used in manufacturing of storage or disposal containers, cells, etc. for nuclear and/or hazardous waste and material, thus reducing  waste  volumes   and  costs  resulting  from  the decommissioning of nuclear (or similar chemical processing) facilities.
