Abstract: HAND-HELD ELECTRICALLY SELECTABLE LABELER             Abstract of the Disclosure There is disclosed a hand-held labeler having a print head with electrically selectable printing elements for printing and applying pressure sensitive labels.  The labeler has a housing with a handle and structure for mounting a roll of pressure sensitive labels releasably carried on a carrier web.  The labeler has a movable section which mounts a keyboard and a control circuit on a circuit board.  The control circuit controls the printing elements.  Labels are printed by the printing elements as the carrier web is advanced, and labels are delaminated at a delamin-ator and dispensed into label applying relation to an applicator.  The print head is mounted on a support and is continuously spring-urged toward the platen.          Movement of the print head toward the platen is limited to prevent damage.  The support and the print head can be moved away from the platen from the out-side of the labeler to facilitate threading of the web.  The print head support can be skewed to provide uniform pressure contact of the printing elements with the labels.  An electrical energy source, for example a battery, can be located in a hole in the label roll.  Electrical energy from the battery ter-minals passes to the control circuit via contacts associated with the label roll mounting structure.          In another embodiment, the handle can comprise a rechargeable battery.  The drive includes an elec-trical stepping motor and in another embodiment, the drive is mechanically accomplished.         Printing is accomplished by a plurality of individually controllable printing elements, prefer-ably arranged in a single line array disposed on the print head in a direction transverse to the direction of advancement of the web.  The array may be only one character width or height long, or may extend across the entire width of the web, in order to permit any size characters of any font and any orientation to be printed.  When a long array is used, a serial-to-parallel converter may be incorporated in the print head to reduce the number of connections that need be made to the head.  By utilizing thermal printing ele-ments, the characters can be made to appear as if they were formed of individual print elements, or as if they were continuously printed simply by control-ling the length of time that the printing elements are engaged to thereby control the amount of smear and burn produced on the web.

Abstract: ABSTRACT        The invention regards a submarine electric cable provided with a tubular stiffening-means in correspondence of the uneven stretches found at the depth of the body of water where the cable is laid.  The invention also concerns a method for disposing said tubular stiffening-means around said cable, during the laying operation, on that tract of cable that is comprised between the capstan on the cable-ship and the surface of the water itself.          According to this invention, said tubular stiffening-means is endowed with a rigidity that is greater than that of the cable itself - in such a way that the cable is not subject to any bend-ing surpassing the minimum bending radius admissible - i.e. beyond the value which gives origin to impairments in the cable itself.  According to a preferred form of realization, said tubular stiffening-means is formed out of a plurality of tubular elements, each one of which is comprised by two shells having C-shaped cross-sections and annular corrugations.  Said shells are connected to one another and joined also to the contiguous shells of the plurality, by means of 'collars' - each one of which is constituted by two semi-collars that are fixable to one another, having C-shaped cross-sections and annular corrugations that can be disposed in the annular corrugations of said shells.

Abstract: ABSTRACT     A single-sheet (i.e. two-surface) rear projection screen for television applications is described, in which the front or viewer-facing surface is formed with vertically running lenticules for horizontal image light distribution and the rear or projector-facing surface is formed with horizontally running lenticules for vertical image light distribution.  There is no need for a diffuser.  The lenticule profiles on both surfaces vary as a function of distance from the projection axis in a manner calculated to accomplish several optical objectives:  collimation, cosine power fall-off compensation, and rearward reflection gradient compensation.  Computer programs for calculating the profiles are disclosed.

Abstract: Device for Adjusting Electron Beams in a Cathode-Ray Tube Abstract of the Disclosure A magnetic ring for adjusting colour purity and convergence is secured to the electron gun of a colour-picture tube. It encloses an oblong area which is perpendicular to the plane defined by the three electron beams produced by the electron gun. The shape of the magnetic ring 22 is chosen so that the y-distance 46 of the ring from the central axis 42.1 of the central electron beam is greater than the distance of the ring from the respective central axis 42.2 of an outer electron beam. This selection of distances influences the focus of the beams.            Magnetic rings of this kind can be used in all multi-beam cathode-ray tubes and particularly in colour-picture tubes with an electron gun producing three coplanar electron beams.

The end ring includes a connecting extension which is fused with the vessel when the latter is made by casting.  After the vessel is filled, a cover made of a material having a structure similar to that of the end ring can be welded to the latter.  In this way, a subsequent heat treatment of the vessel which would otherwise be necessary is avoided. The vessel and end ring can be viewed as being the vessel assembly and a method of making this assembly is also disclosed.

A first embodiment incorporated as part of a well test string includes a packer for isolating a wellbore interval and a perforating gun connected in the string below the packer which is fired in response to development of a greater pressure in the annulus above the packer than in the isolated interval, thereby causing perforation at "underbalanced" conditions.  A modified "full-bore" embodiment has an annular configuration firing mechanism as part of a tubing string and fires the perforating gun in response to development of a predetermined difference between the pressures at a point in the annulus and a point in the central bore of the tubing string.

Abstract: INVENTOR:   GERHARD KINDLER            INVENTION:  DRIVE CONTROL FOR A TRANSPORTATION SYSTEM, ESPECIALLY AN ELEVATOR               ABSTRACT OF THE INVENTION           In this drive control the regulating circuits for the rotational speed of a drive motor and of an eddy current brake are matched in their static and in their dynamic behavior so that a common regulator may be used for both regulating circuits.  The matching is achieved by interposing a current regulation circuit for regulating the excitation current of the eddy current brake to the rotational speed regulating circuit.          The  output of  the  common  regulator  is  supplied via a linearization member as a reference value to a regulator in the current regulation circuit during the deceleration phase.          During the acceleration phase the output of the common regulator is supplied to a matching element matching the variation of the torque to the variation of the torque during the deceleration phase with respect to time.  The output of the matching element is connected to the control member of the drive motor via a linearization member.  By means of the linearization members the characteristics of a d.c.-shunt motor are approximately achievable. A distance regulating circuit is superposed on the rotational speed regulating circuit. The distance reference value is derived from jerk and acceleration magnitudes during the acceleration phase as well as during the deceleration phase,  so that an optimum travel  curve  is achievable.
