    摘要: The method of present invention and the device used therein is directed for characterizing unknown metallic flakes present in an existing coating on a substrate such that a matching metallic paint composition can be formulated and applied over the substrate to produce a metallic coating having characteristics, such as flop, that match the existing coating. The method includes directing a beam of light at a preset intensity towards a target portion of a target coating; directing a reflection of the portion to a photosensitive surface to capture a target image of the target portion; measuring characteristics of the unknown metallic flakes in the target image at said preset intensity; correlating the characteristics of the unknown metallic flakes in the target image to stored characteristics of known metallic flakes at that preset intensity to identify one or more the known metal flakes that match the characteristics of the unknown metallic flakes; and displaying the identified one or more known metal flakes that match the characteristics of the unknown metallic flakes. Once the characteristics are known, a formulator can then formulate a metallic paint that can be applied over the surface of a substrate, such as a repaired autobody, to produce a metallic coating that matches the remainder of the autobody.

    摘要: An oxygen sensor for measuring oxygen in the ppb range. The sensor comprises an electrochemical cell. The oxygen is metered to the cathode based on gaseous phase diffusion to provide a measurement proportional to volumetric concentration. Hydrogen is metered to the anode in an amount in excess of the oxygen being reduced at the cathode. A current is generated which is linear to the volumetric concentration of the oxygen in the sample gas. The concentration of the oxygen is measured based on current generated.

    摘要: A reservoir of electrolyte is placed in communication with the electrolyte of an electrochemical or electrolytic cell which is adapted for oxygen analysis. A cathode is placed in the electrochemical cell and an anode is placed in the reservoir, with a potential of 1.5 VDC applied between them. At the cathode a mild electrolysis of water occurs and a film of highly reactive hydrogen is generated. Similarly, oxygen is generated at the anode. The equilibrium partial pressure of the dissolved oxygen in the electrolyte of the electrochemical or electrolytic cell is reduced via its consumption in the reaction with the hydrogen to form water. Oxygen generated in the reservoir is allowed to effervesce. Thus, an electrolyte devoid of dissolved oxygen can be maintained which allows an accurate analysis of the gaseous sample stream.

    摘要: An oil-water emulsifier comprises a Venturi member having an inlet for receiving oil, an oil-water emulsion outlet and an opening extending therethrough from the inlet to the outlet. The opening of the Venturi member comprises a diameter-reducing portion which connects to a throat portion having a substantially smaller diameter than the inlet, the throat portion being connected to an expanding portion extending from the throat to the outlet, the diameter of the outlet of the opening being substantially greater than that of the throat portion. A plurality of water injection holes extend from the outer periphery of the Venturi member to the throat portion so as to be in communication with the oil flowing through the throat portion, the injection holes being preferably substantially perpendicular to the direction of oil flow through the throat portion. Also disposed is an oil-burner boiler system incorporating the above-described oil-water emulsifier.

    摘要: In an oil fired boiler (with a combustion chamber and a burner which blows a flame into it) there is a J-shaped heat-exchange duct, built on the combustion chamber floor out of thermally ultra-conductive and non-corroding pipes and fittings. Because of the extreme rigidity and brittleness of these, our structure is designed with masonry-like constraints on duct layout: Must rest on floor--never two attachments to anything--must not rely wholly on cement for stability.The J-duct becomes hot from the radiation in combustion chamber. It serves to heat secondary air and delivers it at suitable discharge regions from which it will join the base of the entering flame.The tip of J's long leg is outside chamber and gets secondary air from blower. This leg extends into chamber through its front wall then, curving around, its short leg extends forward and ends at location next to front wall's hot face. The heated air is either discharged at this location through an orifice, or else is carried up in a tower-like riser duct and discharged at a higher discharge point almost directly above the location where the short leg ends.

    摘要: 1,104,774. Body fluid testing device. J. P. GALLACHER. 11 Aug., 1966 [21 Oct., 1965], No. 35934/66. Heading B1X. [Also in Division A5] A liquid-testing device comprises a tube at one end portion of which is colour-change indicator means located in spaced relation with the internal surface of the tube. The tube includes means which provides liquid communication between the other end of the tube and the indicator means so that the indicator means may be exposed to, and thus may convey information relating to, liquid which initially is adjacent this other end portion of the tube. The indicator means may comprise an absorbent carrier, for example of paper, on which is absorbed a colour-change indicator; the indicator may be an acid-base colour-change indicator, for example litmus, phenolphthalein, methyl orange or phenol red. In the embodiment illustrated in Figure 5, the indicator means is in the form of an absorbent band 22" carrying a colour-change indicator and removably mounted on the outer wall surface 24" of the tube 10" at the end portion 12" thereof by means of a plastics or metal sleeve 46. The liquid communication means is provided by a plurality of perforations 28" formed in a zone 44 to extend through the wall of the tube from the internal wall surface 26" thereof to the indicator means; alternatively or in addition, the liquid communication may be provided by a plurality of capillary bores 40 (see Fig. 3) and/or by a channel filled with wicking material. In the embodiment of Figs. 2, 3 and 4 (Figs. 2 and 4, not shown), the absorbent band 22 is mounted between the inner and outer wall surfaces 26 and 24 of the tube. The liquid-testing device is of especial use in medical or surgical procedures.
