Title: Improvements in photographic emulsions
IPC: G03C1/047
Filed: 1949-09-02
Abstract: 670,458. Photographic emulsions. KODAK, Ltd. Sept. 2, 1949 [Sept. 3, 1948], No. 22850/49. Class 98 (ii). Silver halide forming reagents are mixed together in a solution of zein in an aqueous lower aliphatic alcohol such as ethyl-, methyl-, or isopropyl alcohol, or aqueous acetone. The zein acts as peptizer and the dispersion produced may be further dispersed in a colloidal binder such as polyvinyl alcohol, for hydrolysed cellulose ester, or, particularly, gelatin, to provide an emulsion; but, preferably, the zeinsilver halide dispersion is first washed and then dispersed in benzyl alcohol and this latter dispersion is dispersed in gelatin or other colloid by means of a colloid will, to give an emulsion which can be developed and fixed in normal processing solutions; or, this emulsion may be gelled, noodled and washed to remove the benzyl alcohol, furnishing an emulsion composed of particles of zein enclosing silver halide crystals and this is less developable at a low pH than a corresponding gelatin or polyvinyl alcohol emulsion. At pH 9-12 it is readily developed. Colour sensitizers and if desired colour couplers may be dissolved in the benzyl alcohol and an emulsion so prepared may be mixed with a conventional gelatinsilver halide emulsion, coated on a support, exposed and developed first with a normal developer for the gelatin-silver halide emulsion and then with a high pH developer for the zeinpeptized emulsion, couplers being added to the developer if none are already present; or, three of the zein peptized emulsions each containing a suitable sensitizing dye and colour coupler may be dispersed in gelatin, to give mixed grain emulsions. Shellac, rosin or ester resins may be added to the zein. An example describes preparation of a washed silver iodobromide-zein-gelatin emulsion for use as one component of a mixed grain emulsion, and test results (a) comparing development at varying pH as compared with a similar gelatin emulsion; (b) showing resistance to sensitizing of the zein emulsion by a sensitizer added in the external phase; (c) showing effective sensitizing by a sensitizer included in the benzyl alcohol; (d) showing that removal of the benzyl alcohol provides resistance to low pH developers; (e) showing that increased quality of zein in the emulsion gives increased resistance to low pH developers are provided. Specifications 542,703, 542,704 and 670,457 are referred to.

Filed: 1964-06-04
Abstract: 1,063,099. Valves. SWF-SPEZIALFABRIK FUER AUTOZUBEHOER GUSTAV RAU G.m.b.H. June 4, 1964 [July 19, 1963], No. 23113/64. Heading F2V. [Also in Division F1] In a rotary pump, a passage 13 connecting a chamber for pumping gears 11 to an outlet pipe-socket 4 houses a non-return valve 16 and a pressure-relief valve 17, the latter being situated adjacent a passage 21 communicating with a reservoir or sump 7 containing a pipe 22, which is connected to an inlet passage 12 on the low-pressure side of the gears. The valve 16 is slidably mounted on one end of a shaft 15 whose other end carries a knob 20, the midportion of the shaft being attached to a flexible diaphragm 23 controlled by a compression spring 19. The valve 17 is constituted by a compressible ring abutting a supporting plate 26, which lies adjacent the diaphragm. In operation, the valve 16 is depressed by fluid flowing in the passage 13; and, in the event of excessive pressure developing in said passage, the valve 17 is compressed by the fluid to effect recirculation by way of the sump 7. Priming of the pump is obtained by manual retraction of the knob 20 against the action of the spring 19 so that first the valve 16 is depressed by a flange on the adjacent end of the shaft 15 engaging with a corresponding flange on said valve and then the valve 17 is compressed by a shoulder 24 on the shaft, thereby permitting circulation of fluid lodged in the sump 7 through the chamber containing the gears 11.

Title: Improvements relating to electric vehicle controllers
IPC: H01H9/26
Filed: 1920-08-06
Abstract: 149,921. Meyfarth, G. L. Aug. 18, 1919, [Convention date]. Controllers, actuating mechanism for; interlocking.-In an electric vehicle controller of the kind comprising the usual running-drum and a reversing-drum adapted to determine the direction of rotation of the motors and the braking connexions, the two drums are mechanically interconnected and interlocked by mechanism so arranged that, when the reversing-drum is moved either through the intermediary of the running- drum or directly by its own handle, it moves through a greater angle than that of the corresponding operating-handle. As shown in Figs. 1 and 2, the running-drum W<1>, which is directly driven by the handle K<1>, is formed with a cam 2 and with a slot for the locking engagement of a spring-actuated lever 4. The reversing-drum W<2> is driven from the handle K<2> through the differential gearing constituted by the internally toothed flange 8 on a disk 7, the intermediate pinion 6, and the wheel 9 on the drum shaft 10. The pinion is carried by a forked arm 5 loose on the shaft 10 so that it may be oscillated slightly in one direction or the other by the cam 2 on the running-drum. The " off " position is shown in Fig. 2; the reversing-drum is first rotated slightly until the locking-lever 4 drops into one of the deep notches a, b, c for forward running or into one of the similar notches a<1>, b<1>, c' for reverse running, whereupon the spring 11 frees the running drum from the locking lever 4 and the running drum may be rotated forwards to run the motors up to speed or backwards for braking. In the backwards movement, the lever 5 is rocked by the cam 2 and the pinion rolling upon the stationary segment 8 rotates the reversing drum to the braking position. By reason of the differential gearing, the angle of movement made by the reversing drum is greater in all cases than that of the operating-handle which directly or indirectly produces it.
