Abstract:
The invention relates to a method of improving the performance of a jetting assembly in an apparatus for jetting droplets of viscous medium on the fly onto a substrate. The jetting assembly is releasably mounted in the apparatus and comprises a nozzle, an ejection mechanism connected to the nozzle, and a viscous medium container connect to the eject mechanism. Information relating to an XY-position and a Z-position is obtained together with information regarding the exit velocity a droplet of viscous medium has when it exits the nozzle. The information is used as a basis for adjusting a trigger position of the nozzle for the subsequent jetting of droplets. The invention also concerns such a jetting assembly comprising storage means arranged to receive and hold calibration information of properties of the assembly obtained during calibration measurements.
Abstract:
In a film forming method for forming an optical multilayer filter by detecting the thickness of each layer by means of an optical thickness monitor (OTM) 15 and by controlling a film forming apparatus 11 based on the OTM detected output: the light source of the OTM 15 is formed by a variable wavelength light source whose wavelength is variable over the range of null1 nm to null2nm, including null nm; the optical thickness of each of null/4-oriented layers is optimized within the range of null1/4 nm to null2/4 nm; the wavelength of the variable wavelength light source 12 for each layer is selected so that its transmittance reaches an extreme value at the optical thickness of each layer; and the formation of each layer is stopped upon detection of the extreme value of the transmittance.
Abstract:
The present invention is directed to a nozzle capable of producing a high impact waterjet when supplied with a source of ulta-high pressure liquid. The nozzle is constructed and arranged to infuse fluid into a high velocity stream of liquid passing through the nozzle to create a bubble rich waterjet. When the waterjet strikes against a surface the bubbles implode, amplifying the impact of the water against the surface.
Abstract:
There is provided a method of making a composite abrasive compact which comprises an abrasive compact bonded to a substrate. The abrasive compact will generally be a diamond compact and the substrate will generally be a cemented carbide substrate. The composite abrasive compact is made under known conditions of elevated temperature and pressure suitable for producing abrasive compacts. The method is characterised by the mass of abrasive particles from which the abrasive compact is made. This mass has three regions which are: (i) an inner region, adjacent the surface of the substrate on which the mass is provided, containing particles having at least four different average particle sizes; (ii) an outer region containing particles having at least three different average particle sizes; and (iii) an intermediate region between the first and second regions.
Abstract:
A method for applying washcoat dispersion to catalytic converter support bodies. The temperature of the washcoat dispersion and the temperature of the support body are controlled during the coating process. Preferably, the temperatures are substantially equal. The generally equal temperature results in an equal flow behavior of the washcoat dispersion and therefore results in a generally uniform depth of coating layers. Further, such a small temperature tolerance increases the consistency of the quality of the washcoat coating with regards to mass production of support bodies because the viscosity behavior of the washcoat dispersion is highly predictable.
Abstract:
A deposit is formed on a deposition substrate using a deposition gun that burns a mixture of a fuel and an oxidizer to form a deposition gas flow, mixes a powder into the deposition gas flow to form a deposition mixture flow, and projects the deposition mixture flow therefrom. The deposition gun is provided with a flowing coolant. A flow rate of the fuel to the deposition gun, a flow rate of the oxidizer to the deposition gun, a flow rate of the powder to the deposition gun, and a cooling capacity of the coolant flow are all measured. The flow rate of the fuel, the flow rate of the oxidizer, the flow rate of the powder, and the cooling capacity of the coolant flow are all controlled responsive to the step of measurements.

Abstract:
A system and apparatus for detecting and evaluating surface conditions on a road surface and atmospheric conditions simultaneously from a vehicle is disclosed. The system comprises a sensor for detecting the presence of deposited material on a road surface, a detector for determining one or more characteristics of the deposited material such as freezing temperature, process means for converting a detected signal and display means for displaying the condition of the road surface, and a sensor for detecting falling precipitation. An embodiment of the present invention includes a remote sensing apparatus which utilizes electromagnetic radiation to sense actual surface material conditions, temperatures, and composition and local atmospheric conditions at the vehicle as it is moving over a travel surface. This information is then processed through a computer in order to determine those additional steps necessary to apply additional materials to the road surface in order to minimize hazardous driving conditions.
