Title: Movement-adaptive video signal reproduction circuit e.g. for VTR - unfolds luminance signal and selectively outputs luminance signal from delay circuit or unfolding circuit
Inventor: SHIN HYUN-KU
IPC: H04N5/208
Filed: 1992-06-26
Abstract: The circuit includes an unfolding circuit (10) which unfolds a folded luminance signal containing the full bandwidth of the input luminance signal. The input luminance signal is delayed by a set amount in a delay circuit (20), and a motion signal is detected (30) from the luminance signal. Two controllable attenuators (40,50) are provided for selective output of the luminance signal from the unfolding circuit or the luminance signal from the delay circuit, depending on the detected motion signal. An adder circuit (60) sums the luminance signals from the first or second attenuators. The delay time of the delay circuit is pref. equal to the processing time required by the luminance signal unfolding circuit. ADVANTAGE - Improved resolution by reproducing image dependent on motion.

Title: Compsn. for gene therapy, esp. of viral infections and tumours - comprises anti-sense DNA or RNA inserted into long terminal repeat or transposable element and e.g. virus envelope as carrier
Inventor: MEYER FRANK ANDREAS HARALD
IPC: A61K47/48
Filed: 1992-07-29
Abstract: Compsn. comprises (1) antisense viral RNA and/or viral or oncogene DNA provided with suitable promoters and incorporated into long terminal repeats; (2) a virus envelope, suitable both for the size of the antisense genome which is to be transferred into cells and for specific uptake into target cells; and (3) enzymes and chemicals to assist integration of the antisense nucleic acid. Alternatively, the nucleic acid component of (1) is formed as a transposable element and/or the virus envelope in (2) is replaced by receptor-specific substances to which the antisense nucleic acid is bonded. USE/ADVANTAGE - The compsn. is used to inhibit replication of viruses and tumour genes, for treatment or prevention and is practically free of side effects. A partic. application is treatment of AIDS, where control of sec. infections can also be provided (since the nucleic acid may be derived from many different viruses to impart multiple specificities). Prenatal immunisation against retroviruses is possible and immunity will be transferred to offspring. The compsn. is unaffected by most viral mutations since small variations in the sequence are not enough to prevent hybridisation. It can be produced quickly and in large amounts, and the same process is applicable to all viruses.

Title: Glyco-proteins derived from Halobacterium salinarium - useful in treatment and prophylaxis of diseases by non-specifically stimulating the immune system
Inventor: PIEL NORBERT DR
IPC: C07K14/195
Filed: 1992-08-10
Abstract: Glycoproteins including the aminoacid sequence Glu-Glu-Pro-Asp-Gln-Thr-Thr-Val-Asp- Gln-Pro-Glu-Asn-Asn'-Gln-Thr-Met-Thr' -Thr'-Thr'-Met-Thr-Glu in which Asp' and Thr' respectively are bound to an acidic oligosaccharide by an N-glycosidic bonding and by a complete or partial O-glycosidic bonding to a neutral oligosaccharide are new. The glycopeptides may be elongated at (i) their N-terminus by up to 740 aminoacids (AA), and at their (ii) C-terminus by up to 54 AA, possible including N- and O-glycosidically bound oligosaccharides and/or polysaccharides. USE/ADVANTAGE - The glycopeptides are useful in medicaments for therapy and prophylaxis of patients with bacterial, viral, fungal and parasitic infections by boosting the unspecific body defence. The new glycopeptides are more effective in protection against infection and in increasing the colony stimulating factor (CSF). In an example, the 600 bp fragment of H.salinarious DSM668 was cleaved with subtilisin and the glycoproteins of the sequence above were shown to have a very good immunostimulating activity. The activation of tumour necrosis factor (TNF) activity in sera was determined by cytolysis of TNF-sensitive WEHI164/13 cells. NMRI mice together with WEHI-cells in FCS/RPMI medium were incubated overnight at 37 deg.C and 7% CO2. The TNF serum level was increased after treatment with the glycoprotein. To test the prophylaxis for acute infections (peritonitis, sepsis) 24 mice were either treated with the glycoprotein or glycopeptide or with physiological NaCl soln.. After 24 hr they were injected intraperitoneally with 10x LD50 of Staphylococcus aureus ATCC13709. After 7 days, none, 3/24 and 9/24 mice treated with 10 mg/kg of NaCl glycoprotein and glycopeptide respectively survived. 0/24, 6/24 and 12/24 survived when treated with NaCl, glycoprotein and glycopeptides respectively.

Title: Moulding device for applying finishing layer to component
Inventor: FISCHER WILLI
IPC: B29C51/08
Filed: 1993-01-15
Abstract: A device for applying a finishing layer, e.g. fabric (6) to a component (7) consists of upper (5) and lower (4) tool halves between which the finishing layer (6) and component (7) are pressed together with an adhesive. One or both of the tool faces has an elastomeric cover (1) which is held against the tool (4) surface by vacuum and has at least two centring areas (2) comprising raised or recessed areas which engage in corresponding features in the adjacent tool face.Pref. undercut lips may be included on the edges of the elastomer shell (1) and engage in grooves in the tool sides. Increased pressure can be applied to certain tool areas by introducing raised areas (8), formed by thin layers, between the shell (1) and the tool (4) surface. Tolerance variation can also be compensated by varying the shell (1) thickness and hardness. Use of a hygroscopic shell surface in contact with the finishing layer (6) gives a damping effect which is useful with sensitive materials, e.g. velour.

Title: Manual control device having a control knob
Inventor: WUESTENBERG DIETER PROF DR ING
IPC: G05G5/06
Filed: 1993-02-20
Abstract: In a manual control device having a control knob which is held in a housing in a bearing so as to be able to be pivoted about two orthogonal axes about a fixed point, the bearing is constructed as an elastomeric link, whose elastic reset force is directed from all deflected positions towards the zero position of the control knob. An elastomeric link of this type yields, on the one hand, a precise mounting and, by means of the possible one-piece solution, replaces a plurality of mechanical components with respect to previous solutions. In the case of suitable dimensioning, additional reset elements for guiding back the control knob into its zero position can either be completely omitted or these can be dimensioned to be correspondingly smaller. In addition, rubber or a corresponding plastic for the elastomeric link also protects against the penetration of influences of moisture into the interior of the housing and thus also has a sealing function. The elastomeric link, as a simply produced one-piece component, thus replaces a plurality of components previously necessary for mounting, resetting and sealing or simplifies their constructional configuration.

Title: Method for monitoring the height of bonding wires
Inventor: DOEMENS GUENTER DR ING
IPC: G01R31/311
Filed: 1993-09-29
Abstract: Measuring methods known to date for testing bonding-wire height (19) are very expensive, cannot be used in a production line and therefore do not allow complete testing of a production process using an automatic bonding machine. A method is described with which the maximum bonding-wire height (19) on the stationary or moving bonded chip (5) is measured in the production line. For this purpose, a light plane is produced by a focused laser beam (18), the focus of which is located over the middle of the chip (5). The deviation (12) from a straight line over the entire measuring path (13) is kept to a minimum. It is possible to detect either the height of the bonding wire (4) protruding to the greatest extent, the existence of a bonding wire (4) torn off at one end and protruding vertically, or a condition of falling below a maximum height (19). <IMAGE>
