Title: A method of preparing highly dispersed water-insoluble vat dyestuffs and phthalocyanines
IPC: C09B67/42
Filed: 1959-03-09
Abstract: Vat dyestuffs and phthalocyanines are obtained in a highly dispersed state by dissolving them in 90-93% by weight sulphuric acid, pouring the solution into a saturated aqueous solution acidified with sulphuric acid of a sulphate of bivalent iron, copper or zinc, the colloidal acid salt of the bivalent metal which separates forming a carrier for the simultaneously separating vat dyestuff or phthalocyanine, removing the colloidal acid salt by dissolution in an excess of water and filtering off the dyestuffs.  Examples are given in which 1 : 2 : 21 : 11-anthraquinone-dihydroazines and copper phthalocyanine are treated.

Abstract: 526,447. Thermal switches. LANDIS & GYR AKT.-GES. March 16, 1939, No. 8424. Convention date, Jan. 27, 1939. [Class 38 (v)] In an immersion-heater regulator the temperature setting is altered by turning a spindle 8 by means of a knob 9. Rotation of the knob 9 is limited to just under one revolution by the engagement of a downward extension of pin 13 with a stop 11 mounted on a member 10 attached across studs 7 which also carry the interior parts of the regulator. This arrangement ensures that when the cover 16 is removed (after removal of knob 9 and scale 17) the range is not altered by turning knob 9 through more than one revolution. A set-screw 18 engages the serrated edge of scale 17 to fix the scale in its adjusted position.
Patent GB-367597-A (GB)
Title: Manufacture of hydroxybenzo carbazole-carboxylic acids

Title: View-finders and shutters for motion picture cameras
IPC: G03B9/10
Filed: 1945-04-11
Abstract: 592,537. Combined shutters and view finders for kinematograph cameras. WEISSBRODT, J., and BROIDO, J. J. April 11, 1945, No. 9062. Convention date, July 4, 1941. [Class 97 (i)] The combination comprises a shutter made in two parts lying face to face-the part nearer the objective carrying a reflector inclined to the optical axis of the camera and the other part an aperture identical with the exposure aperture-reciprocable out of phase with one another across the exposure aperture so that in turn the exposure aperture is uncovered to allow the formation of an image on the film and is then covered, in which position of the parts the reflector projects an image on to the screen of a view-finder. As shown, one shutter part consists of a rectangular plate 1 having an aperture 1a and a forked extension 1b and the other of a plate 2 having an aperture 2a and an extension provided with an aperture 2b which is slightly larger than the exposure aperture 14. The plates are supported face to face by slideways 3, 4 on the frame of the apparatus. A driven shaft 11 perpendicular to the plane of the shutter carries two cams 9, 10 which engage the apertures 1a, 2a in the shutter plates, the cams being preferably independently mounted as by securing one to a sleeve having two diametrically opposed longitudinal slots engaging a cross-pin on the shaft, and the other to an outer sleeve having a pair of helical slots in which are engaged the outer ends of the same pin on the shaft, so that by displacing the shaft axially, the angle between the cams and hence the exposure time may be altered. Plate 1 carries between its aperture and fork a reflector 5 arranged at an angle to the optical axis which, when carried by the plate into position on said axis, reflects the light from the objective to form an image on a view-finder screen 7 observable either directly or by a lens 8. Under the action of the cams, the shutter plates perform the following cycle of operations : starting with the shutter open when aperture 2b coincides with the exposure aperture 14 and prism 5 is withdrawn from the line of sight, (1) plate 1 is displaced across, and covers, the aperture 14 when the prism produces an image in the view-finder ; (2) plate 2 is displaced so that its opaque end also covers the aperture 14 ; (3) plate 1 is withdrawn leaving the aperture covered by the end of plate 2 ; and (4) plate 2 is withdrawn so that apertures 2b and 14 coincide, exposing the film.
