Title: Improvements in and relating to a method of forming corrugations on a sheet of material and machine for carrying out said method
IPC: B21D15/06
Filed: 1964-12-24
Abstract: 1,089,999. Corrugating; making sheets and holloware. NORD-AVIATION SOCIETE NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. Dec. 24, 1964 [Jan. 14, 1964; Oct. 26, 1964], No. 52424/64. Headings B3A and B3E. Corrugations are formed in a sheet metal workpiece 4 by passing the workpiece between forming rollers having conjugate profiles, a blister C, which occurs ahead of the corrugation being produced, being controlled in extent by means of rollers 25a and 25b. The workpiece 4 is in the form of a sleeve which is welded from a strip which is offset to produce a step 6 and which is internally supported by a sleeve 7. The first corrugation is formed from the step 6 and extends helically around the sleeve, guide rollers along the edges of the sleeve being removed when the first corrugation is produced since that corrugation serves as a guide for an adjacent one, and so on. Longitudinal rollers 16a and 16b, Fig. 5, support the sleeve in a machine 9 during working. The forming rollers are formed by discs 1a-1c and 2a-2c mounted on shafts 10 and 11 which are driven by meshing gears 14 and 15. The shaft 10 is pivotable upwardly to release the workpiece. A plane corrugated sheet is produced by slitting and extending a corrugated sleeve. Similar apparatus, Fig. 15, is used for corrugating a frusto-conical workpiece, the degree of tapering changing on corrugating as shown. The workpiece is supported by adjustable rollers 102a to 102d and 101a to 101d whose axes meet at sources 5 and 5 2  corresponding to the apices of the frusto-conical sections. Bi-convex or bi-concave frusto-conical shapes can be produced and the rolling method is applicable to sleeves which are other than circular. The helical corrugations can have one or more starts. Bellows, aircraft engine cowlings, connecting skirts for missiles, flexible pipes and parts of honeycomb panels can be produced by the method of the invention.

Title: Automatic device for measuring the coefficient of reduction
IPC: G01B11/16
Filed: 1966-12-01
Abstract: 1,109,076. Digital measuring systems. INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE. 1 Dec., 1966 [2 Dec., 1965], No. 53922/66. Heading G4H. [Also in Division G1] In order to measure the reduction in cross-section (coefficient of reduction) of a specimen of mild steel sheet during tensile testing, electrical signals proportional to the log of the applied load, the log and the log log of the extension are generated (the latter two at discrete intervals of extension) and the log of the load plus the log of the extension is automatically plotted against the log log of the extension. It is shown that the slope of the resulting stepped curve is proportional to the coefficient of reduction of the specimen. The load applied to the specimen 1 is measured by four resistance strain gauges, e.g. 4, cemented to the faces of a bar 2 which is operated within its elastic limit. Two strain gauges on opposite faces are arranged as shown, the other two in a direction at right-angles, Fig. 2 (not shown) and are connected to form a bridge, Fig. 3 (not shown). The output of bridge is amplified at 6 and passed to a non-linear attenuator 12 which provides an output proportional to the log of the load signal. The extension of the specimen 1 is measured by a mechanical extensometer 13 which moves between a lamp 19 and a photo-cell 20, a metallized glass plate 15 having a series of slits so that a pulse is emitted from an amplifier 21 for each increment of extension. The pulses control a stepping switch 22 of which one wiper 22b taps off from a preset potential divider 26 a voltage proportional to the log of the particular increment of extension, and a second wiper 22c taps off from a preset potential divider 27 a voltage proportional to the log log of the particular increment of extension. A third wiper 22a energizes indicator lamps. The slits on the plate 15 are spaced so that the log log signals change in equal steps. The log load signal and the log extension signals are added at 24 and applied to one co-ordinate axis of a recorder 25, the log log extension signal being applied to the other axis.

Abstract: 1,167,868. Television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 2 Dec., 1966 [7 Dec., 1965], No. 54125/66. Heading H4F. In a system wherein X-ray images are converted into corresponding television signals and slid signals fed to recording means, said recording means comprise a plurality of magnetic tapes with individual control for starting and stopping the recording of the signal thereon, whereby only signals corresponding to X-ray images of interest are recorded and retained for future replay and viewing. An X-ray image of the object 3 is converted to corresponding T.V. signals by means of T.V. camera 5. These signals are fed for local viewing to T.V. display 9 and also via amplifier 22 to switches 26, 27 and 28, controlling the feed of the signals to the respective recording heads 12 of tape recording assemblies 6, 7 and 8. Each assembly comprises a closed loop of magnetic tape 10 having a loop 11 around which the recording/replay head 12 rotates preceded by an erase head. Each tape loop is moved by an intermediate jockey wheel 17, said wheel being moved, by energization of solenoid 18 on closure of switch 30, to couple a driving wheel 15 coupled to motors 13, to tape bearing wheels 16. Each tape is changed from a recording to a replay mode by closure of switch 40 &c., whereby solenoids 33 and 34 are energized, opening a connection 35 in the record circuit and closing a connection 36 in the replay circuit. Thus, with switches 26/28 and 30/32 closed successive X-ray images are recorded on the three tapes, and in turn erased. When an image of interest is seen on viewer 9, switches 26 and 30, for example, are opened, thereby stopping both the further recording on tape assembly 6 and the ensuing erasure of the recorded interesting image. Further interesting images may be likewise recorded and retained on assemblies 7 and 8. To replay and display the image recorded by assembly 6, switches 40 and 30 are closed, whereby the image is fed via amplifier 22 to the display 9. Depression by one movement of switch 44 earths the output of camera 5. To store the recorded images, switch 44 is further depressed to feed the replay output to a tape store 43.
