Abstract: ABSTRACT OF THE DISCLOSURE           A travelling carriage for strips or slats of vertical blinds has a housing, a pivot pin arranged to be connected with a strip and supported in the housing for pivoting about a verti-cal axis so as to turn the strip about this axis, a mating mem-ber pivotable about a horizontal axis and engaging with a pivot pin so as to pivot the latter about the vertical axis, wherein the pivot pin is supported in the housing tiltable about a tilt-ing axis which is transverse to the axis of the pivot pin and parallel to the axis of the mating member, so that when one or several strips, for example, meet an obstacle, the pivot pin can tilt and disengage from the mating member so that no damage will be caused on the carriage,  This result is achieved by support-ing the pivot pin in a lower wall of the housing in a floating manner without the requirement of complicated structures like slipping clutches and the like.  The housing and the lower wall are elastically deformable, so that the carriage can easily be assembled and allows the tilting of the pivot pin.

The molar composition of the raw materials is as follows : t TiO2, x SnO2, y ZrO2, a NiO, b La2O3, where t is between 0.9 and 1.1, x is between 0.1 and 0.4 moles, y is between 0.6 and 0.9, a is between 0.015 and 0.06 moles, b is between 0.01 and 0.1 moles with an addition of iron of 0.0035 mole in respect of one mole of TiO2 obtained, for example, from the use of steel equipment for the grinding operation.  When x is in the vicinity of 0.35, the coefficient of thermal varia-tion Tf is reduced to zero and the quality criterion Q.f is high.

Abstract: MAGNETIC SIGNATURE SURVEILANCE OF NUCLEAR FUEL       ABSTRACT OF THE DISCLOSURE Typical nuclear fuel material contains tramp ferromagnetic particles of random size and distribution. Also, selected amounts of paramagnetic or ferromagnetic material can be added at random or at known positions in the fuel material. The fuel material in its non-magnetic container can be scanned by magnetic susceptibility change detecting apparatus to provide a unique signal waveform of the container of fuel material as a signature thereof. At subsequent times in its life, the container similarly can be scanned to provide subsequent signatures.  Comparison of the signature reveals any alteration or tampering with the fuel material.

Abstract: ABSTRACT     A regenerative braking system for a linear induction motor includes a control device to increase the frequency slip in a braking mode and reduce the regenerative capacity of the motor. The control device is regulated by sensing means which monitor the voltage of the external power conductor and increase the slip if the voltage exceeds a predetermined value.  This reduces the power regenerated by the motor and prevents excessive voltages in the conductor. A latch prevents cycling between the full and reduced regenerative braking to prevent oscillation of the braking force and is reset upon selection of a motoring condition for the motor.

Abstract: ABSTRACT OF THE DISCLOSURE         A method for automatic recognition of white blocks as well as text, graphics and/or gray image areas on a printed master employs the steps of optoelectronically scanning the master and converting the analog scanning signals into digital signals such that a binarily encoded representation of the master is generated.  Horizontal and vertical white blocks are successively searched for in the binary image and the locations of such white blocks are stored.  The binary image thus sub-divided by horizontal white blocks and the binary image sub-divided by vertical white blocks are logically linked to one another in order to locate white "frames" for the individual areas of the printed master.  Such printed master areas framed in white are subsequently statistically analyzed in order to determine whether the framed area represents a text, graphics or gray image area on the printed master.
