Patent EP-0428229-A1 (EP)
Inventor: VAN DER VIS PIETER ANTHONIE
IPC: H03H7/40
Filed: 1990-11-13
Abstract: Tunable high-frequency antenna which has, over its length dimension, a number of built-in switches by means of which antenna sections are defined and frequency tuning takes place through antenna length tuning by disconnecting and connecting said antenna sections. The antenna comprises a pair of parallel wire conductors, incorporated in series with the switches, which form a dipole antennas and which are used both for the high-frequency antenna current conduction and for feeding the switches. The antenna is provided at its central feed point with a control circuit for the frequency tuning. Each switch is formed by a bistable relay with an associated drive circuit which no longer requires power after switching, the disconnected antenna sections with the switches associated thereto being electrically isolated from the remaining part of the antenna after completion of the length matching. The control circuit is so designed that, in each frequency interval corresponding to a particular antenna length, an impedance matching at a freely selectable number of tuning frequencies is achieved with the aid of a circuit containing reactances.

Abstract: Electronic information input via an input means (11) is divided into first and second groups e.g. representing information which may not be modified except by a skilled operator, and information which may be modified freely. The information is stroed in an information file (14) and display elements are stored in e.g. a related information file (16). If a request for modification of one of the information elements is input via the input means (11), a judging means (15) determines, on the basis of controlling information in a controlling information area (15), whether the information element belongs to the first or second group. If it belongs to the first, a display means (13) displays one of the display elements as e.g. a warning to the operator that the information element may be modified only by a skilled operator. A password system may be provided to identify such a skilled operator.

Abstract: L'invention concerne l'emploi de composés en tant qu'amorces, permettant la polymérisation cationique, au moyen d'une activation thermique, d'une activation photochimique (rayonnement ultraviolet), ou d'une activation à bombardement électronique (BE). L'amorce de polymérisation se compose d'un sel de sulfonium hétérocyclique, à substitution aryle ou fusionnée avec un anneau d'aryle, avec un anion non-nucléophile. Pendant l'activation de l'amorce, une liaison carbone-soufre est rompue par une réaction d'ouverture de l'anneau, conduisant à la formation d'un sulfure et d'un carbocation (ion de carbonium), dans la même molécule. Ledit carbocation déclenche la polymérisation. Comme l'activation ne conduit pas à la fragmentation de l'amorce-molécule en des molécules plus petites, aucun produit moléculaire de décomposition contenant du soufre ne se forme, de sorte que l'on n'assiste pas à une évaporation ou à une migration à partir du polymère, provoquant une mauvaise odeur. Certains composés décrits sont également des composés nouveaux en soi. L'amorce de polymérisation de l'invention a une des formules structurelles suivantes (I) et (II).

Title: Hollow-section sealing strip made of elastic for sealing arched tunnel roofs.
Inventor: HERWEGH NORBERT
IPC: E21D11/38
Filed: 1990-08-24
Abstract: The hollow-section sealing strip of the invention has, viewed in cross-section, a number of identical grooves (8) and a row of channels (9, 10). The channels have different cross-sections, however. The outer channels (9) are basically conical in cross-section with a rounded vertex (91) and a curved base (92). The inner channels (10) are basically circular, part of the circle being formed by a straight line (101). In addition, the side (5) of the hollow-section strip designed to make contact with another, identical strip has two outwards-sloping surfaces (12) forming protruding corners (14). These specially shaped cross-sections produce particularly pressure-resistant sections (11) between the channels (9, 10) in the interior of the strip and strong corner zones (13) between the outer channels (9) and the strip edges (6) adjacent to them, thus giving a particularly effective sealing action against penetrating water.

Abstract: 5 n7 A remote keyless entry device providing vehicle access which utilizes a friend/foe screening technique comprising an initial sequence of two pulses which precede a transmitted code. The first pulse (24) is transmitted on a 50 kHz carrier frequency while the second (26) is transmitted on a 38 kHz carrier frequency. Once the vehicle receives the pulses, a match is acknowledged permitting the subsequently following transmitted vehicle code to be received and compared to the code stored in the receiver memory (116). The specific vehicle code in the preferred embodiment consists of five integers. These integers are transmitted by the transmitter in serial fashion. Each integer is represented as a time interval between a start and a stop pulse. Each time interval is equal to a fixed increment of time multiplied by the respective integer value. The stop pulse of the first integer is the start pulse of the second and the stop pulse of the second is the start pulse of the third, etc. Once the vehicle receiver receives the sequence of integers, the receiver microprocessor (114) compares the integers received with integers stored therein. If a suitable match is accomplished a logic signal is generated and communicated to the central locking unit (118). A central locking unit which controls individual door access mechanisms then positions the respective mechanisms according to the instruction received therefrom.
