Patent EP-1112332-B1 (EP)
Inventor: HAMERSKI MICHAEL D
IPC: C09J7/40
Filed: 1999-02-22
Granted: 2003-06-18
Abstract: A stretch releasing adhesive article for removably adhesively bonding an object to a surface includes a stretch release adhesive strip and a secondary release member. The stretch release adhesive strip includes a first adhesive end portion having oppositely facing major surfaces arranged to adhesively bond with the object and the surface and includes a non-adhesive tab portion. The secondary release member includes oppositely facing adhesive major surfaces having temporary or repositionable adhesive which allows the adhesive article to be repositioned on the surface and object prior to adhesively bonding the stretch release adhesive strip to the surface and object. The adhesive strength of the secondary release member is sufficient to maintain the secondary release member in adhesive contact with the object and surface when the stretch release adhesive strip is stretched during the removal process. After the stretch release adhesive strip is removed from the object and surface, the secondary release member can be removed from the surface by gently peeling or twisting the secondary release member from the surface.

Granted: 2003-09-03
Abstract: A planar electron emitter, based on the existence of quasi-ballistic transport of electrons is disclosed. In its preferred embodiment the planar electron emitter structure consists of a body of finite gap pure semiconductor or insulator, the said body of macroscopic thickness (~1 mm) being terminated by two parallel surfaces and of a set of two electrodes deposited/grown on the said two free surfaces such that when a low external electrical field (~100 V/cm) is applied to this structure, consisting of two electrodes and the said semiconductor or insulating body sandwiched between them, a large fraction of electrons injected into the said semiconductor or insulator body from the negatively charged electrode (cathode) is quasi-ballistic in nature, that is this fraction of injected electrons is accelerated within the said semiconductor or insulator body without suffering any appreciable inelastic energy losses, thereby achieving sufficient energy and appropriate momentum at the positively charged electrode (anode) to be able to traverse through the said anode and to escape from the said structure into empty space (vacuum), said semiconductor or insulator body comprises a material or material system having a predetermined crystal orientation.

Abstract: In a method for generating a second data stream from a first data stream, which comprises a first header and a first payload data block with payload data, the first header is initially extracted from the first data stream. Subsequently the second header for the second data stream is generated. Then, at least a part of the first header is entered into the second header, the part of the first header including information, which allows conclusions as to the origin of the payload data. Finally, the second payload data block is generated, which comprises the same payload data, so as to obtain the complete second data stream. The method according to the invention enables device-specific encrypting of payload data, a flexible, device-specific "copy" for other devices of a user and, in particular, complete documentation of the origin of the present copy, such that effective copyright protection may be realized.

Title: Locking device for security barriers and gates
Inventor: WILLIE O'CONNOR
IPC: E06B11/00
Filed: 2014-03-26
Abstract: The present invention provides a system whereby standard padlocks are fitted to a lockbox which in turn secures a gate or security barrier. Inside the lockbox is a sliding mechanism, which includes a latch to secure a receiver from the gate or barrier, but has varying degrees of freedom of movement along a working axis, depending on the state of locking of the padlocks, and further on the presence or otherwise of a locknut or screw. The opening of any padlock will allow the release of the receiver and the opening of the gate or barrier. However, the padlocks cannot be removed in the ordinary course of the opening and closing of same. Hence, an operator with a key to only one of the padlocks can operate the gate without reference to the other padlock keyholder. The lockbox also facilitates a key holder removing their own padlock, but not the other. <Figure 2>

Title: Vacuum container for refuse
Inventor: BOTTONI MARIO
IPC: B65F/
Filed: 1993-07-26
Granted: 1997-01-24
Abstract: The vacuum container for refuse is a device designed for the storage in a depressurised environment of solid municipal waste of various kinds (organic and otherwise) collected in it. Its essential characteristics are: versatility of use so that in emergencies it is possible to store excess waste in situ or in special open-air yards, the capacity to reduce the original volume of the waste by a significant percentage and, above all, the controllability (by means of the addition of water and/or additives) and collection (by means of pipes with fast couplings) of the biogas and percolate which develops under the action of microbes. This last feature is fundamental because it is possible to interconnect several containers together by means of the above piping, making the storage and collection system modular, for disposal applications; the fundamental biological principles behind the activities of the dumps themselves are respected by this device. <IMAGE>
