Title: Improvements in shutters for cinematograph and still photographic apparatus
IPC: G03B9/10
Filed: 1931-05-05
Abstract: 380,436. Shutters for kinematographic and photographic apparatus. LE BARBIER, E. P. L., 6, Rue Gubernatis, Nice, France. May 5, 1931, No. 13315. [Classes 97 (i), 98 (i), and 98 (ii).] A shutter comprises one or more rotary discs each having one or more apertures, each aperture or combination thereof being so shaped that points on its edges lying on any radius are at equal but varying distances from a circle having its centre at the shutter axis and passing through the lens axis ; the shape of the aperture in a projector shutter may be different from that in the camera shutter, and the shape may be variable during the operation of the apparatus. The variation in the distances may be as desired, and varies the area of cross section of the light beam for the purpose of producing a relief effect. Figs. 9 and 11 show examples of forms of aperture 11 described for single-disc shutters, together with the lens O<1> and the circle passing through its axis. Figs, 12, 13 and 14 show shutter discs 91, 9<2>, 9<3> having respectively an aperture 31 of uniform radial width, an aperture 3<2> of tapering width opening from a sectorial aperture 9<0> and a projection 3<3> and a sectorial blade 93 corresponding in form to the apertures 3<2>, 9<0> respectively. The three discs are mounted coaxially so as to be relatively adjustable and may be adjusted by mechanism shown in Fig. 16. The disc 9<1> is secured to a hollow shaft 12 housing semicylindrical spindles 14, 15 each provided with a pin 16, 17 passing through longitudinal slots 22, 23 in the shaft 12 and entering helical grooves 18, 19 in sleeves 20, 21 respectively carrying the discs 92, 93. The discs are rotated simultaneously by gearing 13, and either of the discs 9<2>, 9<3> may be rotated relatively to the disc 9<1> by knobs 261, 27<1> having pointers moving over scales and geared to spindles 26, 27 carrying cranks 24, 25 engaging slotted rings 28, 29 secured to the spindles 14, 15 ; rotation of the knobs 261, 271 slides the spindles 14, 15 and relatively rotates the disc by means of the helical grooves. Continued rotation of the knobs produces oscillations of the shutter discs between extreme positions, and may be effected mechanically at the will of the operator during operation of the apparatus. For this purpose a worm 32 driven from the projector mechanism drives worm gears 33<1>, 33<2> loose on the spindles 26, 27, and the worm gears are secured to the spindles, as desired, by means of clutch elements 37<1>, 37<2> rotating with the spindles and slidable into engagement with the worm gears by linkages 36<1>, 36<2> respectively secured to one or two spring-pressed knobs 35<1>. Continued displacement of the knobs 35<1>, by hand, against the action of the springs causes the mechanism to rotate the discs.

Title: Improvements in or relating to radio direction finding, range finding and similar observations
IPC: G01S1/02
Filed: 1927-05-20
Abstract: 271,508. Soc. Anon. des Ondes DirigÚes. May 21, 1926, [Convention date]. Electric and magnetic speed indicators. - A stationary-wave or interference system is set up between a primary energized aerial and a second reflecting aerial which re-radiates absorbed energy. The re-radiated energy is modulated by varying the natural tuning or resistance of the reflector, so that the intensity of reception at a third point will depend upon the difference between the distance of this point from the primary and secondary aerials respectively. The secondary or reflector aerial may be any metallic body located in the radiation-field of the primary aerial. In reception takes place near the primary aerial, the intensity of the received signals varies from maximum to minium each time the distance between the primary and reflecting aerials alters by a quarter wavelength. This can be used to estimate the speed of the reflector when this is a moving body, and if the primary emission is directional the bearing of the reflector can also be fixed.

Title: A continuous process for recovering oils from oilseeds
IPC: C11B3/00
Filed: 1923-05-28
Abstract: 214,478. Fauth, P. L. May 28, 1923. Extracting and purifying fatty oils.-In a continuous process for obtaining oil from seeds the successive operations of pressing, extracting by solvents, and refining are conducted at such temperatures as to reduce cooling and reheating to a minimum. The crushed seed is passed into an automatic press 1 from which the oil at about 45-50‹ C. flows through a pipe 25 to a filter 20 and a purifier 22, and the pressed cake falls to a breaker 2 and a countercurrent solventextraction apparatus 3, 5. Solvent of high specific gravity, e.g. trichlorethylene, flows from the tank 10 through a pipe 11, a jacketed extraction cylinder 5, a pipe 12, a pump 13, an extraction cylinder 3, a pipe 14, and the filter press 20 to the purifier 22. The broken cake is conveyed upwards through the cylinders, is passed through a roller press 15 to squeeze out extract, and then falls at about 50‹ C. through a pipe 4 to one or more similar extraction cylinders 5 and presses 16. The exhausted meal is freed from residual solvent and dried by passage through a heater 17 connected to a vacuum pump. The pressed oil and extract are admitted to the purifier 22 in such proportions as to furnish a combined solution of about 25 per cent strength. After the purifier has been connected through a valve 35 to a vacuum apparatus this solution is agitated at about 50‹ C. with the calculated quantity of lye admitted in a very finely divided condition through a perforated coil 32. When saponification of the acids is complete the stirrer is stopped, and after the soap has risen to the surface a saturated solution of common salt is passed in through the pipe 32 to complete the separation of the soap. The extract solution is then forced by a pump 41 to a still 43 in which the solvent is carried away by steam to a condenser 45 connected to a water separator 46 from which the solvent. is raised by a pump 47 to the tank 10. The oil passes from the steamer 43 at about 120‹ C., and is trickled down a chamber 49 against a current of steam to remove the last traces of solvent. At about 110-120‹ C. it is run into a tank 55 and agitated with a bleaching earth, pumped through a filter-press 60 which may be heated to 110-120‹ C., and deodorized by a countercurrent of steam in one or more deodorizers 62 connected to condensers 71, receivers 72, and a vacuum pump 73. The oil is drawn out through a cooler 65, and is raised by a pump 66 to a tank 68 from which it is run through a filter press 69 to storage tanks. The soap and salt water remaining in the purifier 22 are run off through a pipe 51 to a boiler 50 in which traces of solvent are removed by boiling and direct steam, and the soap is dried.
