Abstract: In a mask-frame combination (10) for a colour picture tube, a mask (12) is connected to a frame (11) via welded points (15.2 to 15.4, 15.6, 15.8 to 15.10, 15.12) which are arranged in the corners and adjacent to the long centre axis (16.1) and to the short centre axis (16.k). It is of significance that all the welded points are constructed as double welded points instead of single welded points, as was normal until now. The individual welded points of each double welded point are located essentially at the same height of the mask skirt but are slightly separated from one another. It has been found that the use of welded points which are duplicated in such a manner leads to considerably better shock and vibration strength than the use of the conventional single welded points. At the same time, thermal expansion characteristics are improved. <IMAGE>

Abstract: A method for observing and determining the size of individual particles and for determining the weight distribution of a sample containing particles of varying size, which involves placing a deformable or nondefor- mable particle in a medium, subjecting the particle to an external force, thereby causing conformational and/or positional changes, and then measuring these changes. Preferred ways to measure conformational and positional changes include: (1) determining the rate at which a deformable particle returns to a relaxed state after termination of the external force, (2) determining the rate at which a particle becomes oriented in a new direction when the direction of the perturbing force is changed, (3) determining the rate at which a particle rotates, (4) measuring the length of a particle, particularly when it is at least partially stretched, or (5) measuring at least one diameter of a spherical or ellipsoidal particle. Measurements of relaxation, reorientation, and rotation rates, as well as length and diameter can be made using a light microscope connected to an image processor. Particle relaxation, reorientation and rotation also can be determined using a microscope combined with a spectroscopic device. The invention is' particularly useful for measuring polymer molecules, such as nucleic acids, and can be used to determine the size and map location of restriction digests. Breakage of large polymer molecules mounted on a microscope slide is prevented by condensing the molecules before mounting and unfolding the molecules after they have been placed in a matrix.

Abstract: A safety device for a crane (10) which can make a safety operation precisely taking a relationship between a swinging condition of a boom (B) and a limit working region into consideration. In the device, a working radius (R) and a swinging angle (ϑ) of the boom (B) and projection amounts (d₁-d₄) of projectable support members (105) of the crane (10) are detected, and a limit working region of the boom is set in accordance with a weight (W) of a suspended cargo (C) and the projection amounts (d₁-d₄). A remaining angle (ϑ o ) over which the boom (B) can be swung until the set limit working region is exceeded is calculated, and also a braking angular acceleration (β) at which swinging movement of the boom (B) is braked and stopped without leaving a shake of the suspended cargo (C) is calculated. Further, a swinging angle (|ϑt|) of the boom (B) required to brake and stop the swinging movement of the boom (B) at the braking angular acceleration (β) is calculated, and the thus calculated required angle (|ϑt|) and the remaining angle (ϑ o ) are compared with each other. Thus, a safety operation is performed before the remaining angle (ϑ₀) exceeds the required angle (|ϑt|). Meanwhile, the set limit working region and a current working radius (R) and swinging angle (ϑ) of the boom (B) are indicated on the same screen of a display unit (32).

Abstract: A method for locating the start of a MICR character in E13B font so as to facilitate character recognition. A Calculated Character Start Position (CCSP) is generated by using a predetermined number of voltage samples corresponding to a portion of MICR waveform generated by reading a MICR character on a document. The CCSP is generated by averaging the predetermined number of voltage samples within the window (54) which tends to minimize the harmful effects of noise. Noise from magnetic ink spatter is sometimes wrongly interpreted as the start of a character. A process of "jiggling" is used to assist character recognition techniques by utilizing different character start positions to determine whether or not a template match in character recognition techniques occurs when the new or different character start position is used. Dynamic thresholding is used to avoid false starts or "ringing" due to an immediately previous character which was read having a high intensity waveform compared to the normal intensity expected. The method also employs a technique of having a variable starting point for the search for the start of the next character, with the variable starting point being based on the character just recognized.

Abstract: The method and apparatus of the present invention may be utilized to process a complex hierarchy of interrelated data objects so that a system user may rapidly and effi­ciently traverse the hierarchy from a first selected data object within the hierarchy to a second selected data object without the necessity of manually returning to a known point or "root" within the hierarchy. Each time the system user traverses the hierarchy from a known point to a selected data object (52), the data objects encountered during the traverse are stored (54), along with a set of actions which were necessary to traverse the hierarchy to that point. Upon an indication by the user that a second selected data object is required (56), the system will automatically display (58) the existing path from the known point within the hierarchy to the selected data object in current utilization and the user is then permit­ted to alter the data objects and actions contained there­in to reflect a "path" to a second data object. Thereaf­ter, the system will automatically traverse the complex hierarchy along this newly created path to arrive at the second selected data object. In one embodiment of the present invention, a selected path to a known data object may be saved or "bookmarked" to permit the user to selec­tively return to that particular data object at any time in the future.

Abstract: The invention relates to a process for the direct preparation of 5-carbamoyl-5H-dibenzo[b,f]azepine from iminostilbene which can be carried out readily on an industrial scale. 
<??>5-Carbamoyl-5H-dibenzo[b,f]azepine is of great importance as a pharmaceutical. 
<??>The essential feature of the invention consists in the fact that a hot solution of 5-chlorocarbonyl-5H-dibenzo[b,f]azepine which has been obtained in a known manner by phosgenation of iminostilbene in an inert aromatic solvent is buffered to a pH of 5-6, water is removed from the solution which has optionally been treated with active charcoal and then filtered, by azeotropic distillation, 100-110 % of the theoretical amount of NH3 is passed in at 70-105 DEG C under increased pressure, 10 to 40 % by weight of water, based on the original amount of 5-chlorocarbonyl-5H-dibenzo[b,f]azepine in the solution, are added after the reaction time, which causes the reaction mixture to become fluid due to very rapid changes in the crystal structure, which improves its stirrability greatly, a further 15-25 % of NH3 are finally passed in, and the mixture is allowed to after-react until the reaction is complete.
