Title: Method of and apparatus for detecting image fields on a strip of  film
IPC: G06K17/00
Filed: 1971-07-09
Abstract: 1360625 Controlling punching or marking operations CIBA-GEIGY AG 9 July 1971 [9 July 1970 18 June 1971] 32460/71 Heading G4H [Also in Division G1] Method and apparatus for registering a punching operation in a photographic film strip uses a plurality of photo-electric detectors arranged in a row perpendicular to the film length and the direction in which it is moved, each coupled to a Schmitt trigger to provide a "1" or "0" output according to the intensity of light sensed, the outputs of all the trigger circuits being added and continuously compared with two threshold levels as the film is moved by a stepping motor, the added output also being differentiated and compared with a further threshold, also indicative of polarity. When a frame beginning or end edge passes, the summed digital outputs vary greatly, and pulses indicative of a rise or a fall with respect to the threshold levels are produced. Continuous signals are also produced as and when the summed output is above or below the thresholds and these are logically compared with the pulsed signals to provide pulsed signals indicative of a possible edge of the image. All the circuitry is controlled by a clock which also controls the stepping motor. In the event of a signal indicative of a possible image start being produced, this is delayed by a shift register to be emitted a few clock pulses prior to the corresponding end edge pulse and the two signals are compared with respect to time to provide a positive pulse indicative of an image end edge if the possible beginning and end signals occur within a particular time interval, spurious pulses emitted owing to the peculiarities of the image within the frame thereby being ignored. These signals are successively grouped over 3 frames using shift registers and again if all three pulses in a group are emitted within a particular time interval, a punching command is transmitted. The stepping motor is halted until verification that the punching has been carried out is provided.

Title: Improvements in yarn winding machines
Inventor: RIDGWAY FRANK
IPC: B65H49/30
Filed: 1949-12-19
Abstract: 681,194. Winding bobbins; creels. ARUNDEL, COULTHARD & CO., Ltd. Dec. 1, 1950 [Dec. 19, 1949; May 10, 1950], Nos. 32465/49 and 11619/50. Class 120(ii) Means for supporting a hank of yarn and facilitating withdrawal of the yarn from the hank during winding on to cones or cheeses comprises a suitably supported swift to hold the hank and a separate guide ring which is supported co-axially with the swift and which projects beyond the hank upon the swift, so that yarn drawn off the hank sideways passes over and moves around the top of the guide ring which, along with the hank, is stationary during unwinding but is so supported that it can move angularly and yield at any part at which the yarn tightens or snatches. As shown, Fig. 1, a swift b carrying a hank a of yarn is rotatable on a spindle c supported by a ball head d engaging a recess in a bracket e which is slotted for removal of the spindle. A wire guide ring i is supported on arms h radiating from a boss g at the bottom of the spindle. Yarn drawn from hank a through a stationary guide eye m travels around ring i, the swift and guide ring remaining stationary. A second guide ring j may be provided to prevent the yarn catching arms h. In another construction ,Fig. 3, an adjustable swift b is mounted freely on a spindle c secured in a bracket e. A guide ring i is supported by arms h secured to a collar p held on a boss n, secured on spindle c, by a spring q. The surface of collar p which engages, boss n is rounded so that ring i can yield at any point if the yarn riding thereon tightens during unwinding. Boss a is secured to spindle c by a spring-loaded ball so that the boss, together with ring i can be readily removed from the spindle when a new hank is to be placed upon the swift.

Abstract: 1,271,880. X-ray apparatus. N. V. KABODZEI, E. M. LJUBIMOV, M. N. NADOBNIKOV, and A. A. KROKHIN. 7 July, 1970 [7 July, 1969], No. 33005/70. Headings H4F and H5R. An X-ray television measuring microscopefor determining, for a body under examination, the position of an internal feature shown up by an X-ray image, with respect to an optically observable feature on the external surface of the body-includes an X-ray tube 4 directing a beam 8 through a shielded chamber 1, through the body 3 under examination, to an X-ray image converter 7. The body is mounted on a manipulator 9 permitting measured displacement along the axis thereof, and an optical sighting device 18 with cross-wires 20 is mounted with its optical axis perpendicular to and intersecting the beam 8, and is movable on support 19 parallel to the beam. The body 3 is moved by manipulator 9 until the image on the television screen 14 of the internal feature of interest is located on the image 17 of one of the X-ray opaque cross-wires 16, and the reading on manipulator head 11 is observed. The body is then rotated by the manipulator through 90 degrees so that that surface upon which the X-rays were incident now faces the sighting device 18. The body is then again moved by manipulator 19 until a distinguishing surface feature of the body is coincident with the crosswires 20 of the sighting device, and the manipulator head reading is again observed. Rotation of the body through 90 degrees may, if desired, be avoided by the use of mirrors 22 and 23. In a modified arrangement (Fig. 2, not shown), the sighting device is mounted with its optical axis parallel to, but spaced by an accurately known distance from, the X-ray beam. Reference is made to the provision of further means for moving the object in a direction perpendicular to that of the X-ray beam and the axis of manipulator 9.

Title: Improvements relating to apparatus for simple arithmetical calculations
IPC: G09B19/02
Filed: 1934-11-16
Abstract: 445,052. Teaching arithmetic; indoor games. WEINER, B., 506, Jirhskova ctvrt, Branik, and BLUMAYER, E., 14, Arbesovo nam., Smichov, both in Prague. Nov. 16, 1934, No. 33061. [Classes 132 (ii) and 146 (ii)] A device for use in teaching arithmetic which may be used as a toy or game or for time tests in psychological response experiments comprises two groups or sets of contacts each connected to one of a number of insulated contact plates arranged in a pile and each corresponding to a digit. The contacts can be selectively engaged by movable contacts so as to set up a circuit corresponding to the problem to be solved, this circuit being completed when other movable members adapted to be set for a trial solution are set to the correct solution. When a circuit is completed a bell is rung or during the setting operation an indicating device is operated to indicate the time elapsing before completion of the calculation. In the form shown in Figs. 1, 2, and 4 for multiplication a frame 4 mounted on pivoted arms 2, 3 carries a pair of contact bars 6 with sets of contacts 7 adapted to co-operate with pins or plugs inserted in holes in insulated plate packs 8, 9. Each pack as shown in Fig. 5a consists of ten insulated metal plates numbered 0 to 9 supported by wooden plates 12, 12<1>. The pins are arranged in accordance with the units and tens of the partial products and in order that each pin may make contact with one plate the perforation corresponding to any given pin is larger than the pin except where the pin makes contact with its corresponding plate. A plate 13 with contact strips 14, 15, and 16, on its under surface is arranged above the contacts 7 and above the contacts of arms 10, 11. The contact strips 14 have leads 17, 18 extending to contacts over which can pass the double contacts of an arm 41 that co-operates with contact strips 19, 20. The data is set by manipulating numbered segments 22, 23 and the answer setting segments 24, 25 are set to show the result; if correctly set an electric circuit through a supply battery is completed to ring a bell or to indicate the time taken. A modified arrangement of contacts for adding or subtracting is described. The indicating device as shown in Fig. 13, and 14, comprises an electromagnet 88 which when the circuit is completed attracts its armature 86 to bring a projection thereon into the path of a stop 89 on a disc 82 driven by gearing from a spring barrel 71. The spring barrel carries a stop disc 74 with a projection 76 that engages the end 85 of an escapement lever 83 when the result segment 24 has been restored to its normal position. When the segment is moved to a number selecting position the lever 83 is rocked to free the projection 76 which rotates until the electromagnet is energized. Graduations on the barrel give an indication of the time taken. A modified form of indicating device is described.
