Abstract: 1,171,689. Laser raman spectroscopy. PERKIN-ELMER CORP. April 28, 1967 [May 20, 1966], No. 19674/67. Heading G2J. A laser 36 having a pair of end mirrors 44, 46, produces a beam 30 which is passed through the sample 12 in a cell 10, is reflected back through the sample by a reflector 56, again reflected by end mirror 46 and so on to provide a large exciting flux density in the sample thus producing Raman radiation which is focussed by lens 60 on the slit 61 of a monochromotor. Radiation emitted in the opposite direction is redirected by mirror 72. To prevent spread of the laser beam 30, particularly since the mirror 46, as seen from sample 12, is convex, the reflector surface 58 of reflector 56 is concave. Alternatively a plane reflector is used positioned at the focal plane of a lens. The upper and lower windows 26, 28 of the sample cell 10 may have anti-reflection coatings or they may be positioned at the Brewster angle, to correspond suitably with the end plates 38, 39, of the laser 36. To provide a more compact mounting the laser tube may be parallel to the axis of lens 60 and a 45 degree reflector provided to redirect the laser beam through the sample cell.

Filed: 1970-04-24
Abstract: 1310752 Coating webs AGFA-GEVAERT AG 24 April 1970 [25 April 1969] 19754/70 Heading D1L Webs are coated with high viscosity solutions, e.g. photographic emulsion, by passing the web to be coated past a body of coating solution in contact with it and maintaining the pressure of the coating solution against the web higher at the side of the side of the body of solution at which the coated web leaves (the exit side) than at the side where the web first contacts the solution (the entry side). This excess pressure can be produced dynamically by directing a jet of air or steam against the body of liquid from a nozzle in the form of a slot immediately adjacent to the exit side (Fig. 1) or by maintaining a higher pressure statically at the exit side, this being in the embodiment shown, in chamber 26 or in air lock chambers 28, the pressure maintained by supplying air or steam through pipe 29. The coating solution 24 is supplied to the web 27 by a pumping action of the web as it is coated. In either embodiment coating thickness is controlled by the pressure difference.
