Abstract: 444,839. Stereoscopic kinematography. DUBOIS, L., 10, Rue de Mole, Neuchatel, Switzerland. Jan. 24, 1935, No. 2410. [Class 97 (i)] In the projection of stereoscopic pairs of images arranged in series on the film, the images are projected singly, and with three forward film-feed movements of one image height and one backward movement of an image height, the projector generates or controls a three-phase current the number of cycles of which is equal to the number of pairs of images projected, and the current actuates a single synchronous motor in each of separate rotary shutter devices worn by the spectators ; means for taking the negative images is described. As shown in Fig. 2, the optical system of the camera comprises objectives O<1> O<2> simultaneously producing images in sequence on a film F with the aid of prisms P<1>, P<2> and displaceable mirrors M<1>, M<2>, the height of the images being three sprocket holes instead of the usual four. The feed mechanism of the projector comprises claws P<5>, P<6> operated by cams C<3>, C' on spindles carried by a frame B<2> and driven at equal speeds in opposite directions. The frame B<2> may be rocked about a pivot A by a pin engaging a cam slot E<3> in a disc E<2> rotated at a quarter the speed of the cams C<3>, C<4>, thus causing the claw P<6> to be effective for three forward feed movements and then the claw P<5> to be effective for one backward feed movement. The projector may carry a spindle rotated at one revolution for each pair of film images and carrying conducting rings R<1>, R<2>, Fig. 4, supplied with continuous current through brushes A<4>, B<4> and producing a three-phase current collected by brushes C<4>, D<4>, E<4>. The shutter device worn by each spectator comprises a frame p, Fig. 8, carrying a synchronous motor e rotating a semicircular shutter d secured to its armature a, the motor being driven by the three-phase current so that the shutter cuts off the vision of each eye in succession and in synchronism with the image changes.

Title: Data recording device
IPC: G02F1/29
Filed: 1967-01-19
Abstract: 1,137,323. Data recording apparatus. GENERAL PRECISION SYSTEMS Inc. Jan. 19, 1967 [June 8, 1966], No.2911/67. Headings G2A and G2C. Data is recorded on a moving strip of photosensitive film 10 by giving it an overall preexposure to radiation from a source 12, and then directing on to it a beam of radiation 18 from a second source. The beam 18 can be controlled by means interposed in its path, and has a "developing" or other effect giving a visible read-out on the film strip 10. In one form, the strip 10 may be "Kalvar" (Trade Mark) film, and is given an overall complete exposure by an ultraviolet source 12. The beam 18, which is largely of infrared radiation and is produced by a laser 20, is focused by a lens system 28 to a spot which is scanned across the film by a multi-faceted rotating mirror 30. The heating effect of beam 18 produces a developed image of the trace made by the scanning spot on the film. Interposed in the path of the beam is a Pockels cell 22, which amplitude-modulates the heat energy of the beam according to electrical signals applied to the terminals 26 of amplifier 24. Thus a pictorial image having correspondingly varying degrees of intensity is produced on the film 10. If it is desired to record deflection of the beam as well as amplitude modulation, the beam may be reflected on to the film 10 by a galvanometer mirror Fig. 2 (not shown) or a solid state deflector such as a dielectric plate having a conductive coating on both faces Fig. 3 (not shown). The film strip 10 may alternatively be of photo-chromic material, which changes to its activated colour under ultraviolet radiation, and reverts to its original colour when selectively exposed to the infrared beam.

Filed: 1974-01-25
Abstract: 1456688 Slide rule for pipeline fluid flow calculations C GRAND 25 Jan 1974 [26 Jan 1973 8 Jan 1974] 03501/74 Heading G4B A slide rule of the normal flat straight form and including a cursor (not shown) is provided with logarithmic scales 1-5 arranged for calculations relating to fluid flow in pipes. The scales represent fluid flow rate, fluid speed, diameter of pipe, length of pipe, loss of head per unit length of pipe &c. depending upon the calculation being performed. For example, if the slide 20 is adjusted to position the arrowhead indicator on the left hand end of scale 4 against a known pipe diameter on scale 5, the fluid speed can be read off on scale 3 against the known flow rate shown on scale 1 (cubic metres per hour) or scale 2 (litres per second). Other examples of fluid flow calculations are described. Scales 7-11 are borne by the reverse surface of the slide rule and each represents pipe diameters for a particular coefficient of absolute friction (determined by the nature and condition of the inner surface of the pipe wall). The relevant one of these scales (i.e. the one corresponding to the coefficient of absolute friction of the pipe in question) is used, for instance, in determining the loss of head per unit length of the pipe knowing the fluid speed and the pipe diameter. The slide rule can also be used for ordinary arithmetic calculations. A scale 6 gives the cross-sectional area of a pipe adjacent corresponding pipe diameters on scale 5. In a modification, Figs. 8 and 9 (not shown), scale 6 is eliminated and sectional areas are read off on a shifted scale 2. Moreover, a scale of viscosities is provided between scales 1 and 2.
