Title: Workpiece edge perception light impulse transmitter - uses photo diode, resistance, transistor, thyristor as receiver, gas diode sources
Inventor: GRESSER JUN GERMAN
IPC: B24B49/00
Filed: 1975-10-02
Abstract: The light impulse transmitter which, for optical perception of a workpiece edge and its conversion into an electronical control impulse, has a beam of light sent from a light source (1) through the lense (4). The light beam runs inclined corresponding to the workpiece (5) surface conditions, comes on to the surface, and enters the light receiver (2) at the same angle. When an alteration in the reflection distance occurs, i.e. when the light beam has passed over the workpiece edge, the light receiver (2) no longer reacts. Instead of a photocell, a photodiode is used as light receiver (2), or alternatively, a photo-resistance, transistor, thyristor or several of these in combination. As light source, a GaAs-diode is used which changes its electrical energy directly into infra-red rays.

Title: Reactor vessel penetration leading to internal steam generator - has segmental ring between internal flange of tube and vessel
Inventor: HELM HORST
IPC: G21C13/036
Filed: 1975-10-23
Abstract: In nuclear reactors a connection or orifice through the wall of an outer vessel, esp. a reactor tank (press. vessel) leading to a second, inner vessel, esp. a heat exchanger or steam generator, comprises a length of duct, an inner flange which may be the tube-plate of the heat exchanger and an outer flange outside the outer vessel. The inner flange has a dia. larger than that of the aperture through the outer vessel; the space between this inner flange and the inner face of the outer vessel is filled by a ring composed of >=2 segments to enable it to be introduced through the aperture in the outer vessel. The ring thus bears against the inner face of the outer vessel and is clamped securely in place by the tension in the length of duct which pulls the inner flange towards the outer vessel wall. The face of this ring bearing against the outer vessel is pref. curved to fit closely to the oute vessel. A secure fixing for all the components of the orifice is obtd. which is resistant to the effects of sudden changes in press. in either of the vessels. There is no risk of defective bolts causing a failure.

Title: Yarn feeder for processing, esp. air texturing machine - wide ranging overfeed changes yield new fancy yarns
Inventor: AFEK ILAN
IPC: B65H51/10
Filed: 1976-03-16
Abstract: A yarn feeder for a processing, esp. a texturing machine, has two rollers revolving at different speeds, and yarn guides for bringing the yarn into contact with them, in such a way that the minimum of friction and tension is applied to the yarn, whilst the ratio of overfeed can be alternated at very high speed. The yarn guides consist of a first and second pressure roller spaced one behind the other in the line of motion, on a rocker arm in proximity to the first and the second feed roller, so that the two rollers can press the threads intermittently against either feed roller. The rocker arms pivot on a shaft arranged parallel to the axes of the feed rollers and above a guide bar under which the threads run in a "V" at a tangent to the feed rollers. Each rocker arm is loaded by a spring which presses the roller of one arm against the first feeder roller and the roller of the other arm against the second feed roller, whilst each rocker arm is controlled relative to the spring by a solenoid. The overfeed of the yarn can very quickly be altered and alternated between a number of yarns going through. The range of the types of yarns that can be textured esp. core yarns is considerably increased, and speeds up to 500 yards per min., are used.

Title: Manipulator for ultrasonic weld inspection of reactor duct - esp. of boiling water nuclear reactor, has support system to reach duct around feed water distributor
Inventor: GUGEL GEORG
IPC: G21C17/01
Filed: 1977-07-27
Abstract: An inspection manipulator is intended for the volumetric internal testing of weld seams in ducts and at the edges of ducts, including the adjacent thermally influenced zones of a pressure vessel. The inspection manipulator is mounted at the end of an outrigger arm of a mast manipulator, where the mast can be raised and lowered and the arm can be slewed, extended and rotated about its own axis. The inspection head is itself mounted on a drag lever; this drag lever is mounted as follows relative to the outrigger of the mast manipulator. The outer, free end of the outrigger has a radial arm, with a traveller movable along the arm carrying a further arm parallel to the outrigger axis and continuing in the same direction; the outermost end of this arm carries a radial inward arm, i.e. an arm projecting back towards the outrigger; this last mentioned arm carries the drag level and inspection head. Thus the whole assembly, starting from the end of the outrigger of the mast manipulator, forms approximately three sides of a square providing access to the duct from the mast manipulator along a path which does not follow the axis of the duct. Used partic. for the ultrasonic in-service inspection of reactor pressure vessels. More specifically, for a boiling water nuclear reactor, in which direct axial access to the duct from the inside of the pressure vessel is obstructed by a feed water distributor. The arrangement enables all parts of the inner face of the duct and its junction with the pressure vessel, also the adjacent zone of the pressure vessel, to be reached by the inspection head without removal of the feed water distributor.
