Title: Flying shear for continuous casting plant
IPC: B23D25/06
Filed: 1974-10-30
Abstract: 1484032 Flying shears CONCAST AG 30 Oct 1974 [2 Nov 1973] 47054/74 Heading B3W A flying shear for cutting the products of a continuous casting plant comprises a swing arm 6 carrying blades 5, 7 and driven by a crank 3 mounted in a frame 1 and a guide cam 16 mounted on the frame which, during at least initial movement of the arm, caused by the crank drive, from a position of rest, in which the blades are at a maximum spacing, to a speed which in the blade zone 20 is substantially the same as that of the casting, accelerates the arm in the direction of movement of the casting. A follower 17 on the arm engages a face 9 on the cam, angular adjustment of the cam varying the speed imparted to the arm. The lower blade 5 is fixed and the upper blade 7 is reciprocated in guides 8 by a crank (not shown) in opposed phase to the crank 3. A counterweight 21, or springs (not shown) returns the arm after a cut and a catch 24 retains it. An alternative cam, Fig. 3 (not shown) comprises a main cam (16) positioned by an adjusting nut and screw (37), (38) device electrically driven by means in the casting plant controlling the casting speed. A second cam (32) spring urged against the cam (16), has a face (33) for accelerating the blade zone 20 to a speed greater than the casting speed during opening movement of the blades. In another alternative form of cam, Fig. 4 (not shown) an adjusting member (44) is handoperated and carries a scale (50). A spring (45), connecting the cam (16) to the member is (44), of such strength that the cam will yield if the actual casting speed is less than the speed imparted to the arm 6 by the cam face 9. The cam is always located downstream of the arm if the direction of rotation of the crank 3 causes a component of motion in the direction 18 contrary to the feed direction 15 at the beginning of a cutting cycle and vice versa.

Abstract: 963,698. Electric correspondence control systems. FOXBORO-YOXALL Ltd. May 19, 1961 [Feb. 19, 1960], No. 47755/63. Divided out of 963,697. Heading G1N. The position of a rod 1 (Fig. 1) is such that the force produced by a spring 12 compressed by the rod is equal to that from a nut 10 fixed to the rod and movable longitudinally by a shaft 7, driven by a motor 6 through a variable coupling 3. The torque transmitted by shaft 7 is linearly related to a control current in leads 37 fed into the coupling 3, and this current thus determines the linear position of the rod 1. In another embodiment (Fig. 2), the control current is fed to a coil 21 wound on a spring-biased magnetic rod 22. The flux change associated with a change in control current produces an angular displacement of the rod 22, one end of which is associated with a differential transformer 32, 33, 34, and a difference voltage is fed via amplifier 36 to coupling 3b to reposition the rod 1b .

Title: Apparatus for character recognition
IPC: G06K9/00
Filed: 1963-12-23
Abstract: 1,058,720. Automatic character reading. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 23, 1963 [Dec. 24, 1962], No. 50603/63. Heading G4R. In a character reading apparatus the character area is scanned by a raster of horizontal lines and the signals obtained are sampled to obtain black and white representations which are used to detect shape elements or features and the character is identified from the order of detection of those features. The character field 10 Fig. 1 (not shown) is scanned by a series of horizontal strokes by C.R.T. scanner 11 and the video signals from photo-cell 13 are applied to a pulse generator 14 to obtain binary black and white signals. During each horizontal stroke multivibrator 15 produces 8 pulses. These pass to a counter having three stages 71, 72, 73 the last controlling the sweep circuit 20 to fly-back and start the next line. The outputs of the counter stages T2, T3 define the four horizontal zones α, #, γ, 8 and the left and right halves L, R. The outputs of these stages are gated together to indicate the zones α, #, γ, # by signals on corresponding leads. The zone signals are gated with the output of pulse generator 14 to obtain the following feature signals: IL (a vertical line in the left portion of the field) when four successive scan lines contain a black signal in zone α or the same in zone #; IR (a vertical line in the right portion of the field) when four successive scan lines contain a black signal in zone 8 or the same in zone γ; H (a horizontal line) when any scan line contains four consecutive black signals; and 0 (a gap between two portions of a numeral) when in any scan line black signals are separated by one or more white signals. The consecutive black or white signals required for the above indications are counted by trigger stages, e.g. 22, 23 connected to count four consecutive black signals in one scan line. Once a feature has been identified the corresponding output circuit is disabled until another feature has been identified. This is effected by gates and triggers 70-82. The feature signals, in the form of successive pulses each on an appropriate one of four leads are applied to an identifying circuit, Figs. 2a, 2b (not shown). Since the sequence of detection of the features is the basis for recognition each feature lead is connected to the input of a 6-stage shift-register, all the registers being stepped together. The outputs, each of which indicates a feature and its order of arrival, are combined in a diode matrix to identify the character.
