Abstract: 1303458 Program control WERKZEUGMASCHINENKOMBINAT "FRITZ HECKERT" KARL-MARXSTADT VEB 28 July 1970 36500/70 Heading G3N An information processing arrangement passes input information IE from information input means IM such as a tape reader to an output IA for a numerical control system only provided that the information is correctly read, as determined by a parity test circuit PS, within a predetermined time. Input signal ESS starts clock pulse generator TG whose clock frequency is greater than the signal sequence frequency of information input means IM, and whose output opens interrogation barrier AFS, and via negator N1 cancels old information in store ZSp. The information IE passes via a delay circuit VS and is stored in ZSp. If there is no parity at PS, indicating incorrect information reading, a signal at the output of PS is absent, so that via holding store RSp and negator N2, there is no blocking signal at UE, the generator TG providing pulses so that information IE is iteratively interrogated until parity is attained at the inlet to output barrier stage AGS, the generator TG then being stopped via UE, with the information stored in ZSp. The stage AGS is opened under the control of the information input means IM which provides a signal for example the tape transport signal to a synchronizing circuit SyS, which in turn provides a signal AWS to open AGS. Should the signal AWS be produced when error signal circuit FSS is receiving a signal, via negator N4, indicating lack of parity, a signal to input SE of device IM stops the latter, and provides an error signal FS. Consequently, if parity never occurs at PS, eventually the device IM will cause the production of a signal AWS, which via negator N3 stops the generator TG, and via FSS stops the device IM itself. The device IM may be replaced by an on-line connection. The delay circuit US also gives protection against disturbances such as contact bounce, on the signals arriving at IE.

Abstract: 1328498 Riveting AVDEL Ltd 25 Sept 1970 [26 Sept 1969] 47526/69 Heading B3U A collar carrying device for use with lockbolt swaging apparatus comprises a body portion 33 for attaching the device to lockbolt swaging apparatus, and a plurality of movable arms 34 for releasbly holding a lockbolt collar 12 in front of an annular anvil 18 of the swaging apparatus to allow the stem of a lockbolt pin to be inserted through the collar and anvil, the arms being arranged about an axis and extending forwardly of the body portion 33 and providing inclined surfaces 43 adapted to translate relative axial movement between the device and a part of the swaging apparatus into movement of the arms in a direction transverse to said axis. A collar 12 is inserted in the device so that the end 12b of the collar contacts the outer end of the anvil throat. The swaging apparatus together with the collar is then pushed over the stem 11 until the end face of the collar abuts the workpiece. A drawbolt 24 is retracted causing jaws 22 to grip grooves 17 and pull the anvil 18 over the collar 12, thus swaging the collar into locking grooves 15. The collar carrying device travels forwards with the anvil causing the arms 34 to slide over the cylindrical part 12c of the collar until parts 44 of the arms meet the adjacent face of the workpiece. As the anvil continues to move the front end of the anvil engages inclined surfaces 43 and forces the arms outwardly to release the collar. The outward movement continues until the front face 20 of the anvil reaches the workpiece, Fig. 10. The stem of the lockbolt then breaks at groove 16 and when drawbolt 24 is returned the nose 24a of the drawbolt contacts the rear end of the swaged collar to push the anvil off the collar. The collar carrying device is moved forwardly since dimples 36 in the body portion meet the advancing annular face 37 of the drawbolt thus allowing the arms 34 to close inwardly.

Abstract: 1341005 Measuring strip material BRITISH STEEL CORP 17 Dec 1970 [17 Dec 1969] 61544/69 Heading G1M [Also in Divisions B2 H4] Disconformities of the dimensions or shape of a workpiece are detected by directing a stream of liquid on to a surface of the workpiece, transmitting ultrasonic energy along the stream and utilizing the energy reflected back from the surface through the stream to provide an indication of any such disconformities. In an embodiment for detecting buckling of hot or cold metal strip issuing from a rolling mill the strip profile is sensed by pulse-echo measurement of the distances between the strip surface and several test heads arranged above or below the strip at points spaced across the strip width. Each test head comprises Fig. 2 a Piezo-electric transmit/receive transducer 7 in a housing 6 into which water is fed at 9 as that it passes via apertures 17 into tube 15 and emerges from nozzle 10. Laminar flow is induced by a member 19 having bores 20, and is maintained by annular flange groove 21 which produces a toroidal air motion around a stream at the nozzle exit. Each test head is connected to a respective signal processing channel in which a bi-stable is set just before the expected arrival of the echo pulse, is reset by the echo pulse, and the reset pulse is displayed on an oscilloscope common to all channels and whose time-base sawtooth sweep is synchronized with the acoustic pulse transmission. The sawtooth amplitude is also sampled at the echo arrival instant and the sampled values for the different channels are recorded and may be used for automatic control of the rolling operation or strip feed rate. A single test head scanned across the width of the strip may be used instead of the several heads.
