Title: Apparatus for and method of reproducing an image
IPC: G03B27/68
Filed: 1980-03-05
Abstract: An image represented as an array of digitally valued picture elements is selectively reduced or expanded in size by addition or subtraction of rows and lines of picture elements at positions which are the closest approximation to the newly scaled base, the picture elements corresponding to grey scale values. Reproducing a given image is scanned by photodetector elements (18). The added lines are duplicative of the next adjacent line. Subsequent lines of picture elements are shifted to close the gaps. A dot generator array (such as ink jet array, cathode ray tube, electrostatic or thermal recording system) responsive to the digital values of the picture elements generates the image in scanning fashion across a copy sheet at a modified scale factor in a single or in successive scans, which may occur at the same location or after transmission of the digitally valued pictured data to a different location.

Title: New vector for the production of biologically important peptides
Inventor: DAS GOUTAM
IPC: C12P21/02
Filed: 1991-06-12
Abstract: The present invention relates to the construction of new secretion vectors based on the sequence which codes for the enterotoxin of E. coli.  It was categorically demonstrated that the pre and pro regions of the gene of the toxin were absolutely necessary for the stable extracellular secretion of the toxin.  It was also demonstrated, through specific examples, that when the sequence encoding the nucleotide of a heterologous peptide was structurally fused with the end of the pro region of the st gene, the resultant vector, in an E. coli host, secreted correctly processed heterologous peptides to the extracellular medium.  The present invention also embraces the construction of suitable vectors where it is possible to carry out this gene fusion.  General methods are also described for the creation of said fusions, including: a) recombinant DNA technology and b) the use of site-directed mutagenesis, in vitro.  The present invention also relates to a general method for the purification of heterologous peptides.  These new vector systems can be used for the hyperproduction and extracellular secretion of biologically important peptides.

Patent SE-8705144-A (SE)
IPC: F15B15/26
Filed: 1987-12-23
Abstract: The brake mechanism has application components (9a,9b), fitted on the power transmission unit (8), and which under the control of the pressure medium are applied against the outside of the cylinder tube (1) or against a strip covering the slots. The components are applied with low friction through sliding or rolling, and the braking effect is produced by the piston (4,14a,14b), under the influence of the application components, being applied with friction against the inside of the cylinder tube (1). At its axial end parts, the piston (4) has two support rings (14a,14b) which during movement and in the absence of radial forces have relatively low friction against the interior of the cylinder tube (1), but when radially applied against the inside of the cylinder tube the degree of friction is relatively higher. The piston support rings are of a thermoplastic material, possibly contg. a filler to increase friction, such as talc or fibreglass.

IPC: D21F3/08
Filed: 1990-05-08
Abstract: In order to increase the life of a flexible jacket in a shoe type press roll having a flexible jacket (11), end wall displacing element (28) and jacket stretching element (27), the end wall displacing element (28) are designed to permit a setting of an arbitrary operating position for one roll end wall (18) between two end positions on one of the two stub shafts (13) of the roll, and the jacket stretching element (27) are designed to maintain the stretching force substantially constant, whereby the other roll end wall (22) will be self-positioning and will automatically follow each axial displacment of said one roll end wall (18). Consequently, it will be possible to let the end walls (18, 22) be placed in one end position during a first period of operation and to displace them, for each subsequent period of operation, an adequate distance towards the other end position, whereby the fatigue and the wear of the roll jacket (11), which occur primarily at the axial end of the press shoe (14), will be spread over an area corresponding to the entire displacement distance between the end positions.

Title: Switching element star-delta
Inventor: LOVRENCIC ALOJZ
IPC: H01H3/00
Filed: 1999-03-24
Abstract: Subject of the invention is a switching element star-delta which allows the switching, start-up and operation of asynchronous electric drives and successfully replaces existing switching combinations for controlling electric drives with rated power exceeding 4 kW without limiting its use for any other applications. The design solution of the switching element according to the invention provides three independent positions, which are transmitted via linking elements to the switching part, where a moving flexible contact support by its moving, connects the appropriate terminals thus creating the required electric motor power - star (Y) - with feedback connection to the star point, and after a predetermined period of time the required delta (D) voltage. This is achieved by two magnetic anchors (1) located in the driving section with coils attached by special foil loops (3), and kept at a distance by distance elements (6), which at the same time serve as guides for the common magnetic anchor (2) with cut-out (c), which holds the moving metal support (7), so that the movements of the magnetic anchor (2) are limited.
