Title: Method and means for securing synchronisation in talking motion picture reproduction
IPC: G03B31/00
Filed: 1925-05-23
Abstract: 235,179. De Forest Phonofilms, Ltd., (Assignees of Forest, L. de). June 7, 1924, [Convention date]. Records, combined phonograph and kinematograph; combined working of soundreproducing apparatus with kinematographs.-In apparatus for reproducing a photographic sound record simultaneously with kinematographic picture projection, in which a combined record film is used, it is usual to space the sound-reproducing and picture-projecting devices apart so that the film in its travel passes through one before reaching the other. The invention consists in providing means for obtaining the necessary spacing on the film of the pictures and the associated parts of the sound record. Fig. 1 shows an apparatus for printing a negative sound record 2 and a negative picture record 5 simultaneously upon a sensitized film 8, to obtain a combined positive record. The three, films are fed together past casings 10, 11 respectively containing the sound-printing lamp and the picture printing lamp. To achieve the object in view, the casings 10, 11 may be separated by a distance equal to that which separates the sound-reproducer and the picture projector in the combination reproducing apparatus. Alternatively, the casings 10, 11 may be arranged closely adjacent to each other, in which case one of the negative films will be allowed to travel the necessary distance past its printing lamp before the other film is started. When the sound and picture records are on the same negative film, this may be fed, together with the sensitive film upon which the positive is to be printed, past the two lamp casings arranged in the manner shown in Fig. 1, an adjustable guide-roller being provided between the casings, over which roller the negative film passes and forms a loop. The size of the loop determines the requisite spacing of the two records upon the combined positive film. Fig. 3 diagrammatically shows a reproducing machine comprising a sound-reproducing device 30 and picture-projector 31, the film 8 passing the device 30 before reaching the device 31, the usual intermittent feed-sprockets being provided as shown. To vary as required the effective distance between the parts 30, 31, an adjustable roller 41 is provided over which the film passes and forms a variable loop.

Abstract: 419,530. Cams and tappets. FIRESTONE TYRE & RUBBER CO., Ltd., Great West Road, Brentford, Middlesex, WILLIAMSON, G. A., 179, London Road, High Wycombe, Buckinghamshire, HOLMES, P., 9, Rutland Road, and BLACKWOOD, J., 2, Denbigh Road, both in Southall, Middlesex. May 12, 1933, No. 13896. [Class 80 (iii).] A mechanism for intermittently operating a member comprises a cam device connected to the member and adapted to be engaged and moved bodily by a reciprocating head - piece during a portion of each of its reciprocations to move the member correspondingly, the cam device being actuated by the head-piece during another portion of its movement to vary the part thereof which is engaged by the head-piece at the next reciprocation and permit variation of the extent of successive operations of the member. The feed-roller 6, Fig. 3, of a cutting-machine is driven through ratchet mechanism by a gear wheel 8, which meshes with a sector 9 reciprocated by a link 10, pivoted to a head 11. The head 11 is fixed to a rod 12 slidably mounted in brackets 13, 14 and carries a pivoted disc 16 provided with adjustable radial pins 18 and axial pins 20. A head-piece 23 is adapted to slide on the rod 12, and is reciprocated by a link 24, and crank mechanism. On the upstroke, the headpiece slides on the rod until it engages one of the pins 18, after which it propels the rod and rocks the sector 9. On the downstroke the head-piece engages a stop 29<a> fast to the rod and restores all the parts to normal position and also, by means of a pawl 22 engages one of the pins 20 and rotates the disc to a new position, thus presenting a new pin 18 to its next upstroke and altering the effective length of the stroke. A spring pin holds the disc in its different positions. In a modification a toothed headpiece 31, Fig. 6, slides within a bracket 33 fast to a rod 34 and engages a sector 37 pivoted to the bracket. The sector is adapted at the end of its upstroke to engage a pin on a disc 32, and carries a pawl 41 to rotate the disc. A counterweight may be linked to the bracket at 44.

Filed: 1936-05-18
Abstract: 472,710. Wireless receiving circuits. KRAMOLIN, L. L. DE. May 18, 1936, No. 14102. Convention date, May 18, 1935. Addition to 449,240. [Class 40 (v)] In a receiver of the heterodyne type as claimed in the parent Specification, wherein remote control is effected by electromagnetically varying an inductance or electrostatically varying a capacity in the frequency determining circuit of the local oscillator, the I.F. system includes at least one oscillating stage of the so-called " Slaby-rod " type. In Fig. 1, the input circuit of the frequency changer 4 comprises a low pass filter 2, severely attenuating frequencies over 1500 kc. ; the rejector circuit 3 cuts out strong undesired signals. A high or short-wave intermediate frequency is used, high selectivity being obtained by the use of a " Slaby rod " 5 which is a long iron-cored inductance of small diameter and high distributed capacity on which standing waves are produced. A tapping 10 arranged at a voltage antinode on the coil 5 is connected to the inner grid of the pentode signal rectifier 9, a second tapping 13 being taken from a voltage node through a phasing impedance X and transformer 14 to the suppressor grid of 9. Slight detuning of the circuit 6, 5 causes the standing waves to move along the rod 5, the resulting energization of circuit 13, 14 acting in degenerative sense on the valve 9. A frequency multiplying stage may precede the " Slaby rod " coupling. If a number of I.F. stages are used, " Slaby rod " stages may alternate with weakly damped ordinary stages. Remote tuning is effected by varying the inductance of the coil 18, which with condenser 17 forms the tuning circuit of the local oscillator, and is wound on a ring-shaped iron-dust core 19 between the poles of electromagnet 20, the magnetization of which is varied at the remote point 23, the meter 22 being calibrated in wavelengths. Alternatively, or in addition, the condenser 17 may have a dielectric of Rochelle salt, and its capacity may thus also be varied from the remote point by varying the applied control voltage. Fig. 2 shows a system by which volume and tuning control may be effected at will with two control leads from the remote point, which leads are also used for the low-frequency signal currents. The tuning control 18, 19, 20 is used as in Fig. 1, a second system 24, 25, 26 being employed for volume control in any suitable manner. The low-frequency transformer 27 is the output transformer of the low-frequency amplifier 16 of Fig. 1, the loudspeaker 29 being at the remote point ; 28 and 30 are electrolytic blocking condensers and 31 may be the field-coil of the reproducer if this is of the energized type. The invention is applicable to remote control installations in submarines, battleships and captive balloons.
