Title: Specimen holder system for upright microscopes
IPC: G02B21/34
Filed: 1980-11-15
Granted: 1983-04-13
Abstract: The invention contemplates an upright microscope construction and a system of interchangeable specimen holders for selective use therewith, to accommodate a variety of types and sizes of specimens, such that, whatever the inserted specimen-bearing holder, the specimen surface to be observed, whether by transmitted light or by reflected light, will be in focus, i.e., in the focal plane or effectively in the focal plane of the microscope. This result is achieved by building into the microscope stage a reference-abutment surface having a predetermined relation to the focal plane of the microscope, and by devising all holders of the interchangeable system to support their intended kinds of specimens in such relation to the part of the holder which abuts the reference-abutment surface, that the inserted holder places the desired specimen surface in the focal plane of the microscope.

Granted: 1986-08-27
Abstract: The invention relates to a method and plant for providing heat recovery from hot and moist gas by water vapor absorption. The hot and moist gas, e.g. a flue gas is led in through a flue gas duct (1) to a chamber where the flue gas is washed in a filter (3) sprayed with water, whereby the gas is also cooled so that the heat from cooling is used for vaporizing a part of the water. In this state the gas is brought into contact with a hygroscopic solution (17) through an absorption zone (16) in an absorption tower (15). After treatment, the gas is taken through a flue gas outlet (18), the hygroscopic solution which was supplied with water vapor being taken to a section for vaporization by means of a vaporizer (26) to which heat (27) is supplied. The latent heat coming from the vaporization is converted in the heat exchanger (33) so that it may be utilized. The concentrated part of the hygroscopic solution is merged with the non-concentrated part and taken (21) to a further heat exchanger (23) for recovering (35) heat for utilization, and subsequently refluxed back into contact with flue gas in the absorption tower (15).

Abstract: A high speed optical switch and a time division demultiplexer using such switch. The optical switch comprises a length of linear material (12) including an outer surface on a portion of which is formed a layer of nonlinear material (11) to form a nonlinear interface (10) at the boundary of the two materials. An input data light beam (14) is propagated in the linear material with a predetermined intensity and angle of incidence on the nonlinear interface to, by itself, cause total reflection of the input beam. A control light beam (11) is also selectively energized and directed at the nonlinear interface with an intensity and angle of incidence to cause a portion of the input data beam to be formed into a self-focused channel or beam propagating in the nonlinear material. The self-focused beam can then be detected at an edge of the nonlinear material. By disposing a number of such switches in the path of a repetitively reflected data beam, an optical time division demultiplexer is provided.

Abstract: A process for producing pressure-sensitive sheet material comprising a sheet-form support having a surface coated with pressure-rupturable microcapsules, such as no-carbon required paper, pressure-sensitive adhesive sheet, etc., which process comprises coating a microcapsule-carrying side of a pressure-sensitive material with a coating solution containing defatted soybean powder prepared by treating with an alcohol soybeans defatted according to a solvent extraction process for denaturation. The coating solution containing the defatted soybean powder shows a depressed increase in viscosity of the solution upon its preparation, shows good solution fluidity and good water retention, and undergoes less changes in solution composition. In addition, it reduces unexpected rupture of microcapsules by weak pressure to remarkably decrease color stain on no-carbon required paper, pressure-sensitive paper, etc.
