Patent CA-2091782-A1 (CA)
Inventor: SCHILLING DONALD L
IPC: H04B1/7113
Filed: 1991-11-14
Abstract: An apparatus for adapting to receive a particular path, having the greatest amplitude, of a spread-spectrum signal with multipath. The spread-spectrum signal is modulated by a chip-code. A chip-code generator (401) generates a chip-code signal having the same chip-code as the spread-spectrum signal. A plurality of shift registers shift the chip-code signal by a plurality time delays. First and second ring counters (405; 409) generate first and second sequencing signals for controlling first and second switching devices (407; 411), The first switching device successively switches between a plurality of taps of the shift registers in a direction of increasing or decreasing delays for generating the chip-code signal with the first time delay. The second switching device successively switches between the plurality of taps of the shift registers in a direction of increasing or decreasing delays for generating the chip-code signal with a second time delay. A first correlator correlates the spread-spectrum signal received at the input with the chip-code signal with the first time delay. A second correlator correlates the spread-spectrum signal received at the input with the chip-code signal with the second time delay. A comparator generates first and second comparator signals by comparing the outputs of the first correlator and the second correlator.

Abstract: L'invention est une méthode de sélection de la cible de transfert pour une unité de communication (40) de système cellulaire numérique qui, par l'intermédiaire d'un site de base de service (10-19), échange un signal reçu. Cette méthode utilise un temps d'avance pour déterminer la distance entre l'unité de communication (40) et le site de base de service (10-19). Elle compare d'abord ce temps d'avance avec un seuil. Ce seuil peut correspondre à une distance égale à une fois et demie le rayon de la cellule de service. Quand le temps d'avance dépasse le seuil, la liste des fréquences des sites de base est modifiée pour inclure les sites de base non adjacents au site de base de service. L'identité de ces sites de base non adjacents au site de base de service peut être déterminée par la direction de l'unité de communication (40). La méthode de l'invention sélectionne également, parmi la liste modifiée des fréquences des sites de base, la cible de transfert pour laquelle l'intensité du signal de demande de retransmission est maximale par rapport à l'unité de communication (40).

Title: Formwork usable to produce surfaces of different curvature
Inventor: JARUZEL KURT
IPC: E04G11/04
Filed: 1992-05-14
Abstract: Formwork (1) for surfaces varying in curvature has a face sheet (2) adjustable with respect to its curvature, girders (3) supporting the face sheet and applied to the girders (3), in spaced relationship to the face sheet (2), there is a boom system which is composed of individual boom members (4,5) bridging the girders (3) and is suitably attached to the girders (3) at the outsides thereof averted from the face sheet (2). Adjustment of the curvature of the face sheet (2) is carried out by altering the effective length of the boom members (4,5) between the girders (3).      The mutually opposed formwork elements are adapted to be braced together by means of formwork anchor ties (6). A crosspiece (4) in the form of a boom member is applied to a formwork element at at least two girders (3) and simul-taneously serves as an abutment for the formwork anchor tie (6), the latter therefore being arranged between and having its reaction forces transferred to the two girders. The crosspiece is likewise changeable in its effective length by its fastening location being adjustable in the longitudinal direction in which the crosspiece extends and transversely to the orientation of the girder, so that the crosspiece (4) is available as an adjustable boom member in altering the curva-ture of the face sheet (2), as well as sustaining the tension forces.

Abstract: ABSTRACT         A fast-curing sealant composition is made from generally  liquid  oligomers  and  has  good  tensile strength, one hundred percent modulus, Shore-A Hardness, and good  insensitivity to water. One part of the sealant composition is generally a polyester or poly-ether oligomer having acetoacetate end groups or func-tionalities thereon, whereas the second part is also generally a polyester of polyether oligomer generally containing primary amine end groups or functions.  The oligomers are generally of a low molecular weight, as from about 500 to about 10,000,  and are modified by compounding with various additives such as carbon black, antioxidants,  ultraviolet  light  inhibitors,  and the like.  Polyfunctional acetoacetate-terminated molecules having 3 or more functional end groups or polyfunctional primary amine-terminated molecules having  3  or more functional end groups serve to increase the crosslink density and modulus of the compositions.  The sealant can be used as a coating or as a caulking type compound. One  preferred  application  is  automotive  windshield sealant.
