Title: Indicators for photoelectrically controlled photographic cameras
IPC: G03B13/02
Filed: 1962-06-19
Abstract: 1, 014, 282. Photographic cameras. EASTMAN KODAK CO. June 19, 1962 [June 27, 1961], No. 23446/62. Heading G2A. In a photographic camera having a photoelectric exposure meter coupled to means for automatically regulating exposures within a range of field brightnesses, there is a scale of field brightness values outside this range and an indicator movable over this such as a function of cell energization to indicate the degree by which field brightness departs from the pre-determined range. The invention is described as applied to the camera disclosed in Specification 1,014,281 wherein exposures are regulated by movement of a sensing member 28, Fig. 7, into contact with the pointer 70 of a photo-electric meter 72 which is movable along an arcuate slot concentric with the curved sensing edge of member 28 to positions dependent on the speed of the film in use; this speed being indicated by an index 171 on the meter 72 and a scale 175 of film speeds. On the same pivot 73 as pointer 70 is an auxiliary pointer 200 with an indicator 202 visible in a window 204. This window is divided into zones 206 each of which is numbered to correspond to the factor by which the minimum field brightness for automatic exposure must be divided to equal existing field brightness, the columns corresponding to film speed. These numbers are also to be found on a scale 224 on the shutter housing, Fig. 3, and by moving a knob 192 into register with the correct number the shutter speed can be set manually, movement of this knob overriding the automatic regulator. Some of the zones 206 may be coloured according to a code. In another embodiment, Fig. 13 (not shown), a mask is bracketed to the index 171 of the meter and has a window to uncover only the column of zones corresponding to the film speed. Another form is described, Fig. 11 (not shown), in which no distinction is made between groups of zones according to film speed, but more informative indices are placed opposite each of a series of arcuate rows.

Title: Improvements in the method of manufacturing sulphuric acid
IPC: C01B17/84
Filed: 1925-09-23
Abstract: 266,397. Skoglund, J. V. Sept. 23, 1925. Sulphuric acid.-The nitrous gases in chamber processes for the manufacture of sulphuric acid are recovered by treating them first with sulphuric acid whereby the nitrogen trioxide present is absorbed, then with water or dilute acid to decompose the nitrogen peroxide and finally with acid in the usual Gay Lussac tower. In the plant shown in the Figure, the nitrous gases issuing from the last of the three chambers 13, 14, 15 enter a small preliminary Gay Lussac tower 19 and they are then treated with water in a scrubber 20, the dilute acid formed being re-circulated. The gases finally pass to the usual Gay Lussac tower 23. Instead of using packed towers, the latter may be empty, the acid in this case being sprayed. After being treated with water, the gases must be given time to oxidize to the trioxide stage; this is preferably effected in the Gay Lussac tower itself to avoid reformation of nitrogen peroxide.

Abstract: 1,033,894. Universal joints. YARSLEY RESEARCH LABORATORIES Ltd. June 10, 1963 [June 21, 1962], No. 23993/62. Heading F2U. A resilient coupling comprises driving and driven members having intercalated blades 3, 4 having the spaces between adjacent blades occupied by resilient elements each of which is formed by two or more components of different hardness to give a flexible response to a light load and a stiff response to a heavy load. As shown a soft component 7 is partially housed in grooves in hard components 6, and is under some compression in the unloaded state of the coupling. Under light loading the soft component 7 is compressed to give a flexible response until under increasing torque load flat faces on the hard components 6 contact each other, whereafter the hard components are deformed to give a stiff response. The soft component may be cylindrical and be disposed axially or radially of the coupling. Several soft components may be used disposed axially, radially or peripherally of each other, and they may be of differing hardness. The various components of an element may be permanently or temporarily interconnected as by bonding, by a flexible link or by grooves and projections. In a preferred embodiment the soft component is formed of natural rubber and the hard component of a polyether polyurethane elastomer. If the coupling components are liable to oil contamination the soft natural rubber component may be replaced by a soft butadiene-nitrile copolymer component.
