Filed: 1960-09-24
Abstract: 942,145. Photographic contact printing apparatus. O.J.MUNZ. Sept. 24, 1960, No. 32883/60. Heading G2A [Also in Division G1] Apparatus for contact printing a plurality of film strips on a sheet of printing paper comprises a plurality of lamps each arranged to shine through one of the film strips and the sheet on to one of a plurality of photo-cells. The strips to be printed are held in a holder 8, Fig. 1, on a lamp unit 7, containing lamps L 1 -L 6 , which is lowered by lever 26 into contact with a plate 33 carrying the printing paper. At rest,the relay R, Fig. 4, is energized, holding contacts K 1  and K 3  open and K 2  closed. Lowering the lamp unit closes switches S A2  and S A3  and opens S A1 , Figs. 4 and 5. A button T is pressed to put a positive pulse at the point P to cut off the right hand section of the triode E90CC to deenergize relay R, closing K 3  to energize relay DW. Relay DW steps on the contacts DW 1 , DW 2  to energize a lamp L 1  and connect a photo-cell Z 1 , to the power supply. The triode is reset by the closing of contact K DW . When the capacitor CS reaches a predetermined charge the triode is triggered to open switch K 2  terminating printing and to step the contacts DW 1 , DW 2  to the next lamp and photocell. When the negatives under all the lamps L 1 -L 6  have been printed the next set are shifted under the lamps manually. To assist adjustment, switch DS is closed to energize a relay D which groups the lamps in a series-parallel arrangement which dims and reddens the light therefrom. The exposures may be made simultaneously with a separate capacitor system for each photo-cell.

Title: Improvements relating to the treatment of cereal flour or dough
IPC: A21D2/36
Filed: 1929-11-02
Abstract: A process for bleaching a cereal dough, particularly dough made from wheat or rye, comprises incorporating in the dough or any of the ingredients from which the dough is made, a small proportion of an auto-oxidizable substance, the dough being then subjected to a treatment (high-speed mixing) which exposes a large surface and rapidly changing parts of the dough to the atmosphere.

To the auto-oxidizable substance may be added a small quantity of a bleaching, oxidizing or gluten-maturing agent, such as a per-acid or an oxyhalogen acid or their salts e.g. persulphates, iodates, formates or an organic p peroxide. Specifications 3686/99, 17248/09, 30350/10 and 318,522, [all in Class 49, Food &c.], are referred to.ALSO:A process for bleaching a cereal dough, particularly dough made from wheat or rye, comprises incorporating in the dough or any of the ingredients from which the dough is made a small proportion of an auto-oxidizable substance, the dough being then subjected to a treatment (high-speed mixing) which exposes a large surface and rapidly changing parts of the dough to the atmosphere.
