Title: Graphite structure
IPC: C04B35/52
Filed: 1960-09-14
Abstract: <PICT:0958376/C1/1> The surface of a carbon mass is contacted with iron, cobalt, nickel and the alloys thereof under conditions such that significant penetration of the carbon surface will take place before such penetration is arrested by the solution of excessive amounts of carbon in metal.  In the drawing a graphite stool has been denominated 10.  A globule of molten metal has been denominated 11. A tangent 12 has been drawn to globule 11 where globule 11 intersects graphite stool 10. Angle A is the angle included between tangent 12 and the upper surface of the graphite stool as measured through the globule. As long as the angle A is substantially not in excess of ninety degrees, molten metal in contact with a substantially pure carbon surface will rapidly penetrate into the interior of the carbon mass.

Filed: 1927-11-28
Abstract: 295,928. Monroe Auto Equipment Co., (Assignees of Becker, F. P.). Aug. 20, 1927, [Convention date]. Fluid-friction vibration-dampers.- A oneway hydraulic shockabsorber connecting the frame and axle of a vehicle includes a connection between a cylinder and a reservoir in which one orifice is controlled by an adjustable needle valve and another orifice is controlled by a pressure-operated valve mounted upon the needle valve. A piston 19, Fig. 2, is raised by a spring on its free stroke and is forced downwardly by a short lever 20 operated by a long lever 15 having a connection 16 to the axle, the levers 15 and 20 being on the same axle and one outside when the other is inside the casing or reservoir 17 in which the cylinder 18 is placed. A non-return valve 22 ensures free upward movement while downward movement is controlled by the flow of liquid through the gap between the needle valve 25 and the hole 24. The needle valve is adjustable from the outside. Additional pressure relief is obtained through the passages 31, 32, Fig. 3, leading to the space between two discs 34, the peripheries of which spring apart when the pressure is high enough and allow escape of liquid to the reservoir.

Title: Pollution monitor and cell combination therefor
IPC: G01N21/64
Filed: 1975-08-01
Abstract: 1483159 Calibration of fluorescence measurement apparatus CELESCO INDUSTRIES Inc 1 Aug 1975 [4 Oct 1974] 32187/75 Heading G1A [Also in Division G2] Calibration of a gaseous pollution monitor which operates by measurement of the fluorescence of the gaseous pollutant, is facilitated by the provision of a composite sample and calibration cell assembly, which can be moved to bring the calibration cell into the optical path when desired. The pollution monitor particularly for monitoring SO 2  pollution comprises an ultraviolet source 12, emitting in the band 2100-2300 A, whose radiation is restricted by filter 18 to .2138 Œ 75 Š, and applied via honeycomb collimator 20 to the cell assembly 16. Fluorescent radiation from a sample is detected at right angles to the input path, by a photo-multiplier 22, via further collimator 30 and filter 28 (4000 Œ 100 Š). The cell assembly comprises a solid block of aluminium or steel, drilled with two or more cylindrical cavities, (as shown, three, 32, 50 and 62). The first serves as the sample cell, through which the gaseous sample under investigation is pumped via flexible tubes. Input and output windows 46, 49 are of quartz as they are for the other cells. The calibration cells, one for each different range of concentrations of the pollutant to be monitored, contain scattering plates 60, 64, which are angled at 45 degrees to the incident  U.V. radiation and serve to simulate fluorescence of SO 2 . Suitable materials are aluminium, gold, platinum and molybdenum, and they scatter  radiation over the range which includes the SO 2  characteristic fluorescence wavelength. The block has affixed to its front surface a plate having apertures of appropriately selected sizes for the sample cell and for the two calibration cells. More than one such plate may be provided. In operation, when desired, the block is rotated manually by shaft 70 to introduce the appropriate calibration cell for the concentration range under consideration and if the meter reading is incorrect, the amplifier gain adjusted accordingly.
