Title: Graphic information compression method and system
IPC: H04N1/17
Filed: 1974-03-18
Abstract: 1469433 Data transmission systems RICOH KK 18 March 1974 [27 March 1973] 11857/74 Heading H4P In a system for compressing graphic information for transmission which is encoded in the form of a pulse train (Figs. 2-4, not shown) divided into lines each in turn divided into data blocks of equal length, a line signal (Fig. 5, not shown) indicates whether each line contains a data pulse, block signals indicate all the blocks within the line containing a data pulse and a compressed signal for a line containing one or more data pulses consists of the line signal, the block signal and only the data blocks identified by the block signal and for a line containing no data pulses consists of only the line signal. The pulse signals (Fig. 2, not shown) representing the graphic information (Fig. 1, not shown) being scanned such as that within a TV camera, are converted into delta graphic form (Fig. 3, not shown) in a delta graphic converter A, Fig. 6. The graphic information may be encoded in a modified delta graphic form (Fig. 4, not shown) in which pulse lengths shorter than a predetermined value are suppressed. A logical register 14 determines which blocks contain delta block information and a block register 18 stores a logically positive "1" signal corresponding to a block containing delta block information. A logically negative "0" signal represents a block which is devoid of delta block information. A logical gate 20 sequentially gates the blocks stored in a buffer register 16 containing delta block information under control of the block signal from the block register 18. A logical unit 24 has its input connected to either one or both outputs 28 and 30 of the logical register 14 and buffer register 16 so that the unit 24 senses whether a line being processed contains delta block information and feeds a positive "1" line signal to a mixer 22 if it does and a negative "0" line signal if it does not. The mixer combines the line signal (Fig. 5, not shown) from the unit 24 followed by the block signal from the block register 18 followed by the blocks containing the delta block information obtained from the buffer register 16. The output from the mixer 22 is fed to a communication link L to transmit the compressed information to a receiving unit of a transmission wire or to modulate a radio carrier or light beam for transmission by laser or fibre optics. An expansion unit to expand the compressed delta graphic in - formation is disclosed (Fig. 7, not shown) which includes a buffer register (32) storing blocks containing delta block information, a block register (34) storing the block signal, a flip-flop (40) storing the line signal and a delta graphic inverter (42, 44, 38) operating opposite to that of the transmission unit of Fig. 6 to regain the expanded graphic information.

Title: Films
IPC: B29C48/08
Filed: 1950-05-12
Abstract: In the manufacture of films by extruding film-forming material and setting the extruded material, the extrusion aperture is fed from a stream of the material by diverting material from the stream through inlet means extending along the path of the stream for a distance substantially equal to the length of the extrusion aperture, the undiverted part of the stream being recycled to a point up-stream of the diversion and the material that enters the inlet-means at any given point along its length issuing from a corresponding point along the length of the aperture, the paths between all these pairs of corresponding points being substantially of the same length.  The weight ratio of diverted to undiverted material is preferably from 1 : 1 to 3 : 1.  Open or closed hoppers and fixed or adjustable extrusion apertures may be employed.  As shown (Fig. 1), the film-forming material is circulated from tank 15 through one of two branches 18, 19 provided with filters 21, 22, then through heat-exchangers 28 or, when no temperature control is necessary, through by-pass 33 to hopper 32, excess material being returned through conduit 37 to tank 15.  Pressure drops across hopper 32 and the rate of material-circulation are regulated by a valve 38. <PICT:0686258/IV (a)/1> <PICT:0686258/IV (a)/2> <PICT:0686258/IV (a)/3> <PICT:0686258/IV (a)/4> The hopper 32 (Fig. 2) comprises a body 39, a extrusion aperture 45, a longitudinal throat 42 and a longitudinal bore 41 containing a centrally disposed conduit 47.  A portion of the material passing through conduit 47 flows through a slot 54 extending substantially the length of the extrusion aperture 45 into annular space 55 and then through throat 42 to aperture 45. A heat-exchange jacket 56 may be provided.  In a modification (Fig. 4) the hopper is of triangular cross-section and a portion of the material passing through conduit 69 flows through registering slots 71, 72 to the extrusion aperture 67.  Slot 72 is yieldably closed by a spring-pressed member 73 (Fig. 6), the member being forced away from the slot when the pressure in conduit 69 exceeds a predetermined minimum, thus ensuring adequate material-circulation.  Instead of a longitudinal slot, the conduit may be provided with a plurality of holes.  The film-forming material may be employed as a melt or in solution in a volatile solvent and numerous suitable cellulose ethers and esters and polyvinyl compounds are specified, to which plasticizers and dyes may be added.

Abstract: 1,132,483. Sensing records. NETHERLANDS POSTAL & TELECOMMUNICATION SERVICES, DIRECTOR GENERAL OF. 18 March, 1966 [24 March, 1965], No. 12014/66. Heading G4M. An arrangement for sensing a document bearing equally-spaced marks (M), Fig. 1 (not shown), between the first and second of which a series of code marks are recorded, and between the second and third of which the inverse code is recorded, comprises a pair of photo-cells spaced by an amount corresponding to the distance between two adjacent marks (M), so that adjacent marks (M) are sensed simultaneously as are also each code bit and its inverse bit. The outputs of the photo-cells f 1  and f 2  are applied to AND gate P1 which triggers T1 each time a pair of marks are sensed simultaneously. After the first coincidence, the total number of marks sensed is counted by T2 and T3 until the second coincidence resets T1. As the successive code marks are sensed, they are entered in respective registers in block c of Fig. 3. AND gate P12 sets T4 if the correct total number of bits (true and inverse) has been sensed between coincidences, and also, just after the second coincidence, block d produces an output rs1 to reset T1-T3 to the conditions which existed after the first coincidence. All triggers T1-T4 are reset to their initial conditions when the next document covers an additional photo-cell. If, owing to a spurious mark, a non-valid code is detected between coincidences, then T4 is not set when rs1 is produced and an additional pulse rs2 is derived from AND gate P13 to clear the registers. Since rs1 again sets T1-T3 to the conditions which existed after the first coincidence, a subsequent valid code may still be detected. If two valid codes are detected, the first is entered in the registers, but on detecting the second valid code, T4 is reset, and rs1 rs2 produced to reset the detection circuits and clear the registers.
