Title: Photographic printing process for the production of coloured images
IPC: G03C7/20
Filed: 1923-10-12
Abstract: 205,501. Schapovaloff, S. Oct. 12, 1922, [Convention date]. Colour photography; films with multiple sensitive layers.-A method of printing three monochrome partial images in register consists (1) in employing three registered negative partial images, preferably on films, which are connected together as by adhesive at one edge, or by perforations engaging teeth on the printing frame, and (2) in printing from these negatives upon three connected sensitive layers, two of which are coated on opposite sides of a thin transparent support such as celluloid. In an example, the registered partial negatives are connected at their edges, for example book-wise, and the positives are printed therefrom on a bifoliate film comprising a thin transparent support of twice the length or breadth of an image, which is coated all over one surface with ordinary sensitive emulsion, and carries on the ether surface a non- actinic screen over the whole area, and a layer of emulsion over half the area, the film being folded centrally so as to provide in superposition an emulsion layer, support, screen, emulsion layer, screen, support, and emulsion layer. The negative films are assembled with the bifoliate film by laying one on each outside surface, and enclosing the third in the fold, and the assemblage is clamped to a glass plate or plates. The first image printed is that on the film-leaf carrying only one emulsion layer; this leaf and its negative are then lifted aside and the exposed surface protected, as with black paper. The remaining two images are then printed either in succession, or simultaneously from opposite sides in a printing-frame adapted for the purpose and provided with clamping-means. In this way three positive images already registered are produced on the bifoliate film. In a modification, the bifoliate film comprises two sensitive layers on opposite sides of a thin transparent support to which is connected a white support such as paper carrying the third sensitive layer. Glossiness in the final picture, is avoided by matting the surfaces of the transparent emulsion-supports before coating. The Specification as open to inspection under Sect. 91 (3) (a) also comprises a modification of the process, wherein the support carrying only one sensitive, layer is separate from the remainder, and is separately printed, and superimposed in register after printing. This subjectmatter does not appear in the Specification as accepted.

Title: Freeze-dryer
IPC: F26B5/06
Filed: 1970-05-27
Abstract: 1315147 Freeze dryer PHILIPS GLOEILAMPENFABRIEKEN NV 27 May 1970 [30 May 1969] 25481/70 Heading F4G Items to be freeze-dried are placed in a vacuum chamber 8 which is in communication with a condenser chamber 6, evacuation being achieved by pump 10. During the freezing part of the freeze-drying cycle, a refrigerant is circulain the directions indicated by the solid arrows from a heat exchanger 2 in the cold head 3 of a refrigerator 4 to further heat exchangers 5, 12, in the condenser chamber 6 and the vacuum chamber 8, respectively. Circulation is achieved by pumps 15, 18, and the temperatures achieved in the chambers 6, 8, are controlled by the relative settings of valves 16, 14, which may be replaced by a single mixing or distributing valve (Figs. 1b, 1c) not shown. When the required operating temperatures are achieved, with the temperature in the condenser 6 lower than that in the freezing chamber 8, a heating device 17 is put into operation to raise the temperature in the vacuum chamber 8 in order to sublime the previously frozen moisture, which is then drawn into the chamber 6 and condensed. During this subliming process the valve 14 is closed, the pump 15 is stopped, and the fluid circulated in directions indicated by the broken arrows. Heat exchanger 2 is designed to offer a greater resistance to the flow of fluid than heat exchanger 5 so that little or no warm refrigerant flows through heat exchanger 2 during the sublimation part of the cycle. An expansion chamber 19, containing gas under pressure, and an excess pressure valve 20 are provided.
