Filed: 1970-12-01
Abstract: 1328150 Recording and playback SPERRY RAND CORP 1 Dec 1970 [29 Dec 1969] 56939/70 Heading G5R A flexible strip record 20, which is aerodynamically supported relative to a plurality of rotating heads 14, is brought to a desired operating position by selectively energizing two solenoids 74, 76 to cause one of two protrusions 66, 68 on a lever 70 to engage a corresponding one of two notches 30, 32 in the record. The record is thereby brought to a position such as in Fig. 4 where the lower left corner of a pin 50 engages the lower left corner of a record aperture 24, and the "quarter-width" line 38 is in the desired setting, or to a corresponding position with the lower right corners of pin 52 and aperture 26 engaged, as in Fig. 5 (not shown) whereupon line 44 is correctly set. Errors caused by expansion/contraction of the record are thus reduced to 25% of the actual change.

Title: Associative Memory
IPC: G11C15/04
Filed: 1968-12-19
Abstract: 1,197,268. Associative stores. INTERNATIONAL STANDARD ELECTRIC CORP. 19 Dec., 1968 [22 Dec., 1967], No. 60320//68. Heading G4C. [Also in Division H3] An associative memory matrix in which data is stored in true and inverse form comprises a number of rows X and column pairs Y having at each crosspoint a diode D1 or D2 and a solidstate device F1 or F2 as shown in Fig. 2. The solid-state device is switched to a low-resistance state by applying a sufficiently high voltage, and to a high resistance state by a sufficiently large current. To erase the data on a row an address decoder applies a voltage to L so that a high negative voltage- U2 is fed to the row. The current passes to earth via F1, F2, setting them to the low-resistance state. To write a word in to a row the address decoder applies a voltage to S and the bits of the word are applied to respective column control units G, each such unit having inputs B1, BO for 1 and 0 bits respectively. Thus a 1-bit causes current to flow from ground via T3, F1, and T7, switching F1 to the highresistance state. To interrogate the matrix a word is applied to the column control units' inputs A1, B1, so applying voltage + U1 to the appropriate wire of the column pairs. Thus if a 1-bit is applied to A1 a voltage + U1 is applied to D1 and dependent on the state of F1 a low or high voltage appears across resistor R. If the interrogating word is the same as a stored word there will be a low voltage across the resistor R of the row on which the word is stored. This voltage will be detected by a threshold unit K. To read a row, the address decoder scans terminal S to apply - U1 to the rows. Voltages are consequently developed across RG3, RG4, of magnitude dependent on the states of F1, F2. This voltage is applied to a result store connected to the column wires. The column wires may be connected to a coincidence circuit to determine whether or not the devices F have been brought to the desired condition during erase or write in. Transistors T5, T6 may be added as shown to eliminate adverse effects of reverse current from the diodes.

Abstract: 1299719 Photo-copying Apparatus CANON KK 29 Dec 1969 [28 Dec 1968] 63115/69 Heading G2A, G2H A photo-copying machine comprises an original stand A; light sources B; a first mirror C movable in a direction parallel to an original, e.g. a book P, on the stand; a second mirror D movable in a different direction; means for displacing both mirrors along their respective directions to scan an original, the displacement being such as to vary the distance between the mirrors while maintaining the normals to the mirrors orthogonal; a projection lens E stationary with respect to the stand A; stationary means defining a slit through which a photo-sensitive member may be exposed to an image formed by the lens E; and means for moving a photo-sensitive member so that an image may be recorded thereon during scanning of an original. As shown, the machine is an electrophotographic apparatus, and the photo-sensitive member is present as part of a drum 1, but the machine may be silver halide apparatus. Also as shown, a non-magnified image is obtained, but a magnified image may be obtained by suitably selecting the velocity of the photo-sensitive member. Sequence of Operations The surface of an insulating layer 13 is charged by means 2; thereby causing charge of opposite polarity to be bound either in a photo-conductive layer 12 or at the interface between the layers 12, 13. An image of the original is projected onto the primary charged surface of the layer 13 through a slit in the shield plate 32 of a corona discharge means 3 which simultaneously imparts to the drum 1 either A. C. corona discharge or a charge of opposite polarity to that of the primary charge. The insulating layer bearing the electrostatic image is uniformly illuminated by a system 4 to increase the contrast, then the image is developed in a section 5, and then a charge of suitable polarity is imparted to the developed image by means 6. A copy sheet is fed from a stack 90 towards a transfer roller 7 where the developed image is transferred. The copy sheet is then fixed and ejected from the machine while the layer 13 is cleaned by a roller 10. Scanning Operation As the drum 1 rotates a drum M is rotated in synchronism therewith, so that a belt N is wound therearound. Consequently belts J and K, which are joined to the belt N, cause the mirrors C and D to move to the right and downwardly respectively as seen, thereby causing the mirror C to scan the original. When scanning is finished, detecting means (not shown) causes a clutch (not shown) to disengage the drums M, 1. Reversing mechanism L then causes the mirrors C, D to return to their initial positions. The first and second mirrors may be positioned Fig. 2, (not shown) so that light reflected to the slit by the second mirror (4') is at an angle of not more than 30‹ to a normal to the original.

Abstract: 639,053. Calculating-apparatus. BIENFAIT, L. A. J. April 30, 1947, No. 11607. Convention date, May 12, 1942. [Class 106 (i)] A machine for calculations relating to railway track, road, electric transmission line or other curves comprises independently adjustable mechanical means c, d which can be interconnected in threes so that a direct displacement of the middle one produces an opposite displacement, of half the magnitude, of the other two, and the algebraic sum of the direct displacements of each mechanical means is indicated, e.g., on a counter m (Fig. 10). The machine may be applied to calculating the displacements to be made at spaced points along a railway track to give it a desired curvature. Equidistant points 1, 2, 3 ..., (Fig. 1), are taken along the track and the " heights " such as f2, f3 are measured and registered in the machine, by adjusting the mechanical means which, as shown, comprises nuts d sliding on rotatable screwed rods c and carrying pointers e moving over scales g. The rods have square ends and can be independently rotated by a crank (not shown). The calculations are based on the rule (approximately true for. large radii of curvature) that an increase a in one " height " a will produce a decrease - in the " heights " at 2 the two adjoining points. Any three consecutive rods c can be interconnected by a crank l (Fig. 7) which can engage the teeth of a crownwheel i on one rod and has a pinion k for meshing with gears h on the two adjacent rods, the gears h rotating once for two rotations of the pinion. The pinion k also meshes with gearing (not shown) connected to a revolution counter m associated with each rod, which counter thus indicates the displacement to be made at a corresponding point on the track when the pointers e have all been adjusted to indicate the " heights " of the desired curve. The counters can be reset by turning the square-ended shafts q.

Abstract: A matte finish is formed on a molten metallic coating on a continuous metallic strip by directing onto the moving coated strip water particles having a size varying between 20 mu  and 40 mu . The treatment is particularly applicable to galvanised coatings on steel strip where it is desired to remove the incidence of so- called "spangling" where the zinc solidifies as large grains. In this case the water particles are impinged on the coated strip at the stage immediately preceding the point at which the coating metal solidifies, the strip being previously moved into and of a bath containing the molten zinc.
