Abstract: A "return on investment" digital database usage metering, billing, and security system includes a hardware device which is plugged into a computer system bus (or into a serial or other functionally adequate connector) and a software program system resident in the hardware device. One or more databases are encrypted and stored on a non-volatile mass storage device (e.g., an optical disk). A tamper-proof decrypting device and associated controller decrypts selected portions of the stored database and measures the quantity of information which is decrypted. This measured quantity information is communicated to a remote centralized billing facility and used to charge the user a fee based on database usage. A system may include a "self-destruct" feature which disables system operation upon occurrence of a predetermined event unless the user implements an "antidote"-instructions for implementing the antidote being given to him by the database owner only if the user pays his bill. Absolute database security and billing based on database usage are thus provided in a system environment wherein all database access tasks are performed at the user's site. Moreover, a free market competitive environment is supported because literary property royalties can be calculated based on actual data use.

Abstract: An article including at least one segment which is capable of being elastically shirred along at least a portion of its length subsequent to manufacture of the article, preferably by mechanical manipulation of a predetermined portion of the elastically shirrable segment. The predetermined mechanically manipulatable portion of the elastically shirrable segment preferably comprises an elastomeric member (20) which is maintained in a prestretched and tensioned condition in the desired direction of shirring. The opposed ends of the elastically shirrable segment in the article are interconnected to one another through the prestretched and tensioned elastomeric member. The prestretched and tensioned elastomeric member is also secured in fixed relation to at least one rigidifying member (15,16) to form a composite structure (10) which is strong enough to resist collapse in a direction parallel to the tensile forces acting upon the prestretched and tensioned elastomeric member prior to mechanical manipulation of the composite structure. The article is elastically shirred by mechanically manipulating the predetermined portion of the shirrable segment until movement of the prestretched and tensioned elastomeric member relative to the rigidifying member is effected. To elasticize the article containing the elastically shirrable segment, the relative movement between the prestretched and tensioned elastomeric member and the rigidifying member must be sufficient to release the tensile forces in the mechanically manipulated portion of the composite structure. This relative movement produces a degree of elastic shirring in the segment, and consequently in the article to which it is attached, in the direction of prestretching of the elastomeric member. The degree of segment shirring is proportional to the extent to which there is relative movement between the prestretched and tensioned elastomeric member and the rigidifying member in the area comprising the composite structure. Thus, the tension in the elastically shirrable segment can be increased by the user, as desired, by mechanically manipulating more of the composite structure. Elastically shirrable segments of the present invention are particularly well suited to high speed article manufacturing operations, since the segments can be applied to the articles in a substantially untensioned condition and their tension released subsequent to article manufacture.

Abstract: A light beam is repeatedly deflected in the longitudinal direction through a holographic element HOE by means of a rotating multi-faceted mirror. This HOE is so formed that the beam entering at different angles leaves the HOE as a telecentric beam. Through a further HOE the telecentric beam is diffracted onto an electro-optic transducer. In the region of the telecentric beam is located an object to be measured, and the time of the interruption of the telecentric beam by means of this object enables the dimension of the latter to be determined. The production of the telecentric beam and the deflection of the latter onto the transducer by means of the HOE allows a simple cost-effect manufacture as well as a simple evalution of the measurements with increased precision. The manufacture of the HOE is likewise simple.

Abstract: An optical device comprises first and second optical waveguides (1,2) connected between respective output and input ports of first and second optical couplers (3,4). The first coupler has at least one input port and is adapted to couple optical signals received at the input port into its output ports in a predetermined coupling ratio. The second coupler has at least one output port and is adapted to couple optical signals received at each input port (7,8) into its output port in a predetermined coupling ratio. The first and second waveguides (1,2) define respective optical paths with substantially the same optical length. The waveguides (1,2) are fabricated from materials which exhibit soliton effects when optical pulses, at working intensities, are injected into the waveguides, such that the pulse propagation is dispersion dependent, whereby the portions of an optical pulse received at the input of the first coupler (3) are coupled into the waveguides (1,2) by the first coupler and arrive sychronously but phase shifted relative to one another at the second coupler (4) after travelling along the waveguides. The device may be configured to provide optical switching and logic functions.

Abstract: The invention belongs to the areas energy technology and methods for transformation of the energy of permanent magnets (from the rotation of the electrones around the parallel atom axises of the permanent magnets) to mechanic energy. The method solves the technical problems to create screen of active type, which can screen magnetic fields, at the samt time screen which does not itself be acctracted or repelled by magnetic field. Other materials screening magnetic fields without themselves being attracted or repelled by the magnetic field do not exist. Iron for example screens the magnetic field but is itself attracted by the magnetic field and in order to pull the iron from the magnet is energy using needed. Martin Denev's method is solving this problem by building permanent magnet structures similar to the chromosomes and nervous system in living organisms, since living organisms have built structures that can both screen magnetic field and the living system is not attracted or repelled by outer magnetic field, even in case of that iron is included in the living system. Only such a chromosome-like permanent magnet structure can build a screen under which protection one can situate against each other two same poles of permanent magnets, which after taking away of the screen can perform work. This cycle can be repeated as much as wanted, in a motor,which transforms the magnetic energy to mechanic. This is no perpetum mobile, since the magnetic energy has its origin in the permanently rotating electrones, and the energy is all the time supplied in the system. In perpetum mobile machines no energy is supplied all the time during the work.

Abstract: Graft polymers in which vinyl carboxylates and optionally further ethylenically unsaturated monomers are grafted polymerically onto polyurethane backbones by free-radical-initiated graft polymerisation, and products of the hydrolysis of the graft polymers, can be obtained by grafting vinyl carboxylates having 3 to 20 carbon atoms and optionally further ethylenically unsaturated, polymerisable and optionally copolymerisable monomers in amounts of from 10 to 99% by weight, based on the graft polymer, onto a polyurethane backbone containing at least 2 urethane groups in the molecule, and, if desired, subsequently partially or fully hydrolysing and/or alcoholising the vinyl ester units and any further hydrolysable monomer units in the grafted-on polymer radicals of the graft polymers. Vinyl esters which are preferred for grafting are vinyl acetate and/or vinyl propionate and possibly vinyl versatate. The graft polymerisation is carried out in solution or in bulk and can also be carried out in emulsion or suspension. Unhydrolysed graft polymers are suitable, inter alia, as adhesives, in particular as hot-melt adhesives. Fully and partially hydrolysed graft polymers are suitable, inter alia, for the production of films. Depending on the polyurethane backbone, the degree of grafting, the degree of hydrolysis and the type of grafted monomers, the graft polymers, compared with polyvinyl alcohol, can have significantly lower melting points, and are thus advantageously suitable for the production of pressed or extruded films under mild temperature conditions without the additional use of organic plasticisers. Hydrolysed graft polymers are furthermore suitable, inter alia, as adhesives.
