Title: Apparatus for scanning information bearing media
IPC: H04N3/38
Filed: 1972-01-12
Abstract: 1378252 Film scanning; APC systems EASTMAN KODAK CO 12 Jan 1972 [18 Jan 1971] 1463/72 Headings H3A and H4F Apparatus for scanning a continuously moving information bearing medium with repeating line scansions includes means driven in synchronism with the movement of the medium for generating a first signal having a frequency substantially equal to an integral submultiple of a predetermined sweep frequency, means for producing a sweep signal of substantially the predetermined frequency and a frequency control responsive to the two signals to control the predetermined sweep frequency. Oscillator 44 generates a 15750 Hz horizontal sweep signal for a flying spot scanner which scans a continuously moving motion picture film, which signal is fed back through frequency divider 48 to provide one input to phase detector 36. The second input is derived from an optical or electromechanical transducer 30 which responds to the 125 indicia provided on track 28 of a disc 10 rotating with the sprocket wheel 12 of the film drive at 6 revolutions per second. The D.C. output from detector 36 is integrated by low pass filter 40 and controls the frequency of oscillator 44. Transducers 20, 22 co-operate with indicia on tracks 16, 18 to produce raster deflection signals and television field rate signals which are used to derive a vertical deflection signal for the flying spot scanner, as described in Specification 1,322,615. If the product of the number of indicia on track 28 and the rate of rotation of the disc is greater than one tenth of the horizontal sweep signal frequency divider 48 may be omitted. The phase detector then locks into the appropriate multiple of the sync. signal from transducer 30. Preferably the sync. signal has a square wave form which effectively samples part of every Nth wave of the sawtooth form sweep signal. To prevent the detector locking into the (N-1)th or the N+1)th multiple of the sync. signal the operating range of the oscillator may be limited to between N-¢/N x 15750 Hz and N+¢/N Î 15750 Hz. To prevent the detector locking into harmonics of the sync. signal or the sweep signal a low pass filter is provided in the sweep signal feedback path to filter out frequencies above 15750 Hz (see Fig. 2).

Abstract: 652,219. Travelling-wave tubes. WESTERN ELECTRIC CO., Inc. Nov. 28, 1946, No. 2191/50. Convention date, Jan. 11. Divided out of 652,155. [Class 39 (i)] In a travelling-wave amplifier, the electron stream is projected at a suitable velocity through a hollow wave-guide provided with transverse parallel conductive baffles or other filter sections, so that an energy interchange occurs between the electron stream and the high-frequency waves propagated down the guide from an input connection to an output connection. The wave-guide 49, Fig. 1, forming a part of the envelope, contains a plurality of transverse partitions 58, for slowing down the velocity of the waves to that of the electron stream. Apertures 60 in the partitions 58, additional to the central apertures 59 for the passage of the electron stream, are provided to give the pass-band of the guide a desirable characteristic depending on their shapes, sizes and locations. The central apertures 59 in the partitions 58, may be fitted with cylinders, Fig. 2 (not shown), and the cylinders 65, Fig. 3B, supported by rods 68, instead of by partitions. The cylinders 65 may be interconnected in series by conductors 95, or in parallel to vary the filter-type characteristics of the transmission path. High frequency loss may be provided in the transmission path to prevent self-oscillation by rods 61, Fig. 1, or by plating portions of the guide structure. The loss may be made sufficiently large near the centre of the guide to absorb completely the input energy, the output energy being entirely generated in the output portion of the guide. Specification 652,155 is referred to.

In an embodiment, a self-aligning bearing 12, Fig. 1 (not shown), of synthetic plastics material, is retained in a housing 14 by the deformation of a portion 36 thereof and is crimped thereto at 39, Fig. 3 (not shown), without preventing a self-aligning movement of the bearing. Spaces 65 and 66, Fig. 1 (not shown), are provided between the bearing 12 and the housing 14 to allow for expansion of the bearing and to effect air-cooling of the bearing respectively. The housing 14 is forced through a hole 52, Fig. 8 (not shown), of a sheet-metal plate 16, the material of the latter entering an undercut recess 40 in a head 38 of the housing 14; knurls 55 may be provided on the head 38.
