Title: Microfilm cartridge and adapter apparatus
IPC: G03B21/11
Filed: 1972-12-08
Abstract: 1419637 Tape cartridges XEROX CORP 8 Dec 1972 [8 Dec 1971] 50666/72 Heading B8M An adapter 20 is provided in order that cartridges 7 may be fitted to a projector (e.g. for microfilm) which would normally accept one particular cartridge construction. The adapter 20 has a first plate 21 with cartridge receiving pins 22, 23 and a rotatable second plate 25 with a clamping device 30. The plates 21, 25 are held in various relative positions by means of pin 28 and openings 24. The adapter 20 may be screwed to plate 10 attached to the projector 1. A film trailer 41 has a pin 40 and slot connection 50 with a film leader projecting from the cartridge 7. The point of exit of the film from the cartridge 7 may be adjusted by flap 72 in aperture 71. In use the trailer 41 is threaded through the film path of the projector (not shown) and the cartridge 7 mounted on the adapter. The position of cartridge mounting can be varied by relative movement of plates 21, 25 and passing pins 22, 23 into a selected two of holes 61, 62, 63. The pin and slot connection 40, 50 is made and clamping device 30 released so that film can be withdrawn. After projection the film is rewound and the connection 40, 50 severed. The trailer 41 remains located in the film path and obviates the need for threading when the next cartridge is attached to the projector.

Abstract: 1,147,069. Mowers; treating crops; distributing fertilizer. B. MULLER. 20 Dec., 1966 [21 Dec, 1965; 5 April, 1966], No. 56925/66. Headings A1D and A1F. [Also in Division B1] A travelling device for mowing green fodder, processing it and distributing the liquid product as fertilizer comprises a casing, forming at one end a screw housing 19 and at the other end a compression chamber 21 having liquid discharge holes 49, a screw conveyer 20 of substantially constant pitch having one end rotatably mounted in screw housing 19 and its other end extending into but not through compression chamber 21, and a removable flat 39 which is retained by a hydraulic cylinder 40 to open at a predetermined pressure in the compression chamber. Green fodder mown by knives 6 is fed to conveyer screw 20 from receptacle 7, and liquid containing nutrients extracted from the fodder pass through holes 23 and 49, is collected in containers 24, and 48 and distributed through 55 and 47 as fertilizer. The fodder is conveyed by screw 20 without substantial compression because of the constant pitch to compression chamber 21 where it is compressed. Liquid discharged through holes 23 into container 24 contain only a small amount of nutrients because of the low pressure exerted on the fodder in the screw housing 19, whereas the liquid passing through holes 49 into container 48 is more concentrated in nutrients because of the greater pressure exerted on the fodder in the compression chamber 21.

Title: Pattern extremity determination
IPC: G06V30/146
Filed: 1969-12-30
Abstract: 1,269,140. Character recognition. INTERNATIONAL BUSINESS MACHINES CORP. 30 Dec., 1969 [13 Jan., 1969], No. 63208/69. Heading G4R. Apparatus for determining the positions of the four extremities (viz. upper, lower, left and right limits) of a pattern on a document, performs a first scan (e.g. Fig. 1A) to detect the pattern, and a second scan (e.g. Fig. 1C) to determine accurately the position of one extremity (e.g. upper limit) of the pattern and approximately the position of each of the remaining three extremities. A third scan (the horizontal raster at the bottom of Fig. 1D), a fourth scan (the vertical raster at the left of Fig. 1D) and a fifth scan (the vertical raster at the right of Fig. 1D) follow in turn to more precisely define the respective extremities of the pattern. The third scan scans the top or bottom portion of the character first depending on the direction of movement of the beam when the character was first encountered (Fig. 1C shows bottom scanned first). Track and hold amplifiers retain and update the maxima and minima of the horizontal and vertical deflection voltages fed to the scanner (a CRT) during scanning of the character. These values, voltages representing present beam position, and reference voltages, are compared, sometimes after shifting using potential dividers, to control the scanning. For example, point 12 (Fig. 1C) is defined by comparing the horizontal deflection voltage with a shifted version of the stored maximum horizontal deflection voltage, and point 13 (Fig. 1C) is defined by comparing the vertical deflection voltage with a shifted version of the stored minimum vertical deflection voltage. The line from point 18 (Fig. 1C) down via point 19 to point 21 (Fig. 1D) uses the stored minimum horizontal deflection voltage and stops (point 21) when the vertical deflection voltage agrees with the stored minimum vertical deflection voltage. Detection of blank scan lines terminate the fourth and fifth scans (Fig. 1D, left and right respectively). Finally, if the vertical and horizontal sizes of the character are acceptable, as determined from the stored maximum and minimum deflection voltages, the recognition raster can be positioned. Horizontal and vertical normalization of the pattern is also mentioned.
