Abstract: ABSTRACT OF THE DISCLOSURE        The present specification describes an apparatus for the inspection of translucent containers comprising a conveyor for transporting a container through an inspection zone, and means for directing a plurality of light beams sideways at the container during its movement through the zone.  Each light beam is directed at the side of the container from a different direction relative to the container, and deflection means cause each of the beams to repeatedly scan the side of the container in a vertical direction as the container moves fully through each beam.  A respective opto-electronic light collector is provided for each beam for providing a respective signal representing the amount of light falling thereon from the respective beam after transmission through the container, and signal processing circuitry is associated with each light collector to examine the signal therefrom according to a predetermined criterion to generate a fault-indicating signal when such criterion is fulfilled.  Means are provided for allocating to each beam a respective area of the container sidewall for which any such fault-indicating signal can be regarded as resulting from an actual fault rather than from a characteristic of an acceptable container, and any fault-indicating signal generated when the respective beam is not scanning the allocated area of the container sidewall is suppressed.

Abstract: ABSTRACT       A method for providing a container with one or more layers of barrier material during the production of the container from a thermoplastic.    A preform (10) is stretched in its axial direction, generally an amount corresponding to the total axial stretching required for conversion of the preform to a container, after which the stretched preform (11, 13) is provided with one or more barrier layers (12, 14), and the preform is then heated and converted to a container.    In one embodi-ment, the axially stretched preform (15) is produced by assembling axially stretched part-preforms (13a,b) covered with one or more barrier layers.    The combined preform is then converted to a container.    By means of the invention, it is possible to reduce the thickness of the barrier layers at the time of their application, which considerably simplifies the latter.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention provides a process for producing vanadium carbide layers on workpieces of carbon-containing iron and iron alloys.  Salt baths containing primarily borates as the base substance have been used at 800 to 1100°C.  The melts were thus rendered   very viscous and the losses on discharge were large.  In accordance with the invention this is avoided with salt baths containing alkaline earth metal and/or alkali metal halides as salts in addition to 1 to 30% of vanadium or ferro-vanadium powder.  Baths of barium chloride with 1 to 50% of sodium chloride are particularly suitable.

Abstract: ABSTRACT:         An optical fibre is coupled to an end face of a semiconductor laser diode and the other end face is coupled to one end of a monomode optical waveguide. The other end of waveguide is terminated in a reflecting man-ner, e.g. by mirror, to reduce the coherence length of the laser. Thus so-called "speckle patterns" are only produced in the transmission fibre over a short distance from the laser and modal noise further on in the trans-mission fibre can be prevented by avoiding the use of non-ideal fibre couplings or other connections having a spatial filter effect within this short distance from the laser.

Abstract: SHIP LOCK SYSTEM WITH HYDROELECTRIC PUMPED-STORAGE CAPABILITY                 ABSTRACT OF THE DISCLOSURE A ship lock system having a ship lock intercon-necting two bodies of water at different water levels.  The system includes one or more underground hydroelectric pumped-storage units connected by one or more penstocks with the ship lock which serves as the upper reservoir to the pumped-storage units so that water can be drained from the ship lock through the penstocks to drive one or more reversible pump-turbines of the pumped-storage units which generates electrical energy, particularly during high demand hours for electrical energy.  A lower reservoir adjacent to the pump-turbines is used to store the water which drives the turbines.  The lowering of the water in the ship lock per-mits ships which entered the lock at the upper water level to leave the lock at the lower water level.  By a pumping action, the pump-turbines can pump the water from the reservoir upward into the ship lock through the penstocks, particularly during periods of low power demand.  The elec-trical power for accomplishing the pumping action can be supplied from other conventional energy sources as well as from tidal, wind, solar and other emerging energy sources. The raising of the water in the ship lock permits ships which entered the lock at the lower water level to leave the lock at the upper water level.

In a first position control means which are adjustable to two positions limit the pivotal movement of the switching lever to movement into a first, partly pivoted operating position, in which first position of the control means the fast-mode idler arm is uncoupled from the switching lever so that the fast-mode idler arm is pivoted. In the second position of the control means the switching lever is pivotable into a fully pivoted second operating position, the fast-mode idler arm then occupying the inoperative position through the coupling of the fast-mode idler arm with the switching lever and the normal-mode idler arm being pivoted into the operative position. In both operating positions the switching lever is also coupled to the head slide.

Abstract: ABSTRACT OF THE DISCLOSURE    An air-fuel mixture intake apparatus for internal com-bustion engines includes a two-barrel carburetor having a pri-mary venturi for supplying an air fuel mixture into a combustion chamber under all loads and a secondary venturi for supplying an air-fuel mixture into the combustion chamber under medium and high loads.  The primary venturi is of a fixed cross sec-tion and the secondary venturi is of a variable cross section.          A vacuum-operated actuator controls operation of a secondary throttle valve in response to a vacuum developed in the primary venturi and subsequently in the secondary venturi.  The secondary throttle valve is interlinked with a primary throttle valve by a linkage mechanism such that the secondary throttle valve is allowed to open when the primary throttle valve opens to a pre-determined degree with the maximum opening of the secondary throt-tle valve being variably contorlled by the opening of the pri-mary throttle valve after the latter has opened beyond the pre-determined degree.  A delay valve is disposed in a primary vacuum signal passageway or a common vacuum signal passageway connected to a vacuum chamber of the vacuum-operated actuator to delay an air flow through the passageway toward a vacuum pickup probe in the primary venturi.  The secondary throttle valve may be mounted on a shaft displaced downstream off the geometric center of the secondary throttle valve.
