Title: Improvements in optical devices for photographic, kinematographic and other purposes
IPC: G02B27/14
Filed: 1926-05-28
Abstract: 257,549. Romer, J. F. May 28, 1926. Prints.-Optical systems for producing simultaneously two laterally reversed images of an object in the same plane consists of a composite prism having total and semi-reflecting surfaces. The rays from an object 0 pass normally through the surface X<1> of the prism P<1> on to the semi-reflecting surface S' common to the prisms P', P<2>, by which they are divided. One portion passes directly through the surface S<1> to the lens L<2> and the other portion of the rays is reflected to the totally reflecting surface R' from which it passes through the surface S' to the inclined surface R<2> of the prism P<2> by which it is reflected to the lens L<1>. Both incident and emergent beams pass normally through the external surfaces of the composite prism, and form images M<1>, M<2> laterally reversed with respect to each other, in the same plane. Modifications of the forms of the prisms are described, in one of which the reflected rays are again reflected at a semi-reflecting surface, and in other of which both divisions of the rays are further reflected before passing out of the composite prism. The. same system may be used to combine by optical projection two laterally reversed images into one composite image. Colour filters may also be used, when employing the system for colour photography.

Abstract: 365,925. Reflex cameras. STEINER, K., 19, Zieblandstrasse, Munich, Germany. May 7, 1931, No. 13539. [Class 98 (i).] In reflex cameras of the type in which the reflector actuates a cylindrical segmental shutter, the shutter is adapted to bear resiliently against the guide-plate. As shown in Fig. 1, the reflector a, pivoted at b, carries a curved shutter c which fits snugly against and bears resiliently upon a curved guide-plate g. When lowered, the reflector is retained by a spring catch d<1> which is released by a trigger e for exposure through the aperture c<1>. By turning down an adjustable stop f, the trigger may be further depressed to cause a second catch d<2> to hold the shutter with the aperture c<1> in front of the lens for time exposures. In a modification the shutter member is separate from the reflector and is resiliently pressed against the guide-plate by a segmental frame connected to the reflector ; lugs on the shutter engage an opening in the frame with lost motion so that the reflector may be lowered without uncovering the lens. Fig. 4 shows a further modification in which the separate shutter k is coupled to the frame by a spring tongue k<2> adapted to snap into recesses g<1>, g<2> in the guide-plate g to retain the shutter in the two end positions.

Filed: 1929-05-07
Abstract: 338,484. Triggs, W. W., (Pan American Petroleum Co.). May 7,1929. Mineral oils, purifying.-A process for purify-- ing hydrocarbon oils such as crude petroleum, shale or cracked oils, consists in treating the oiL with fuming or concentrated sulphuric acid in the presence of liquid sulphur dioxide, simultaneously or previously added to the oil, preferably at a temperature not greater than the boiling point of liquid sulphur dioxide, and thereafter separating the purified oil from the acid residues. The oils are thereby freed from polymerizable, unstable, and sulphur-bearing hydrocarbons. Oil is passed through a pipe 1 to a heat exchanger 2 which is cooled to about 17‹ F. by the outgoing purified oil from the acid treating tower 9, and thereafter passes through a pipe 5 to a treating tank 6 mixed with a regulated flow of cooled liquid sulphur dioxide coming from the tank 46. The mixture rises through a perforated distributing plate 56 and through the acid sludge contained in said tank. The partly treated oil cantaining dissolved sulphur dioxide is discharged through a pipe 8 and enters the base of an acid treating tower 9 where it rises through a distributing plate 10, and through the acid sludge indicated at the level 13, and is treated with sulphuric acid passed through a pipe 44 from a tank 16. The purified oil is discharged through a pipe 20, and the heat exchanger 2, to an evaporator 23 where sulphur dioxide, is removed by a heating coil 24. and the oil is discharged through a pipe 31. The sulphur dioxide liberated in the heat exchanger 2 and evaporator 23 is compressed by a pump 38, and passed through a cooling coil 40 to the tank 46. The purified oil may be submitted to treatment with alkalies or sodium hypochlorite and distilled. The sludge formed in the tank 6 is drawn off through a pipe 49 into a tank 51, and sulphur dioxide is removed therefrom under reduced pressure. The acid in the sludge may be recovered by hydrolysis. Specification 338,483 is referred to.
