Title: Filtre numerique a reponse impulsionnelle limitee
Inventor: ZOU YONGZHONG
IPC: H03H17/06
Filed: 2001-12-06
Abstract: La présente invention concerne un filtre numérique à réponse impulsionnelle limitée pour système de communication mobile sans fil. Le filtre numérique à réponse impulsionnelle limitée offre une très bonne caractéristique de limitation de bande et une grande robustesse pour l'échantillonnage d'une erreur temporelle. Le fait d'utiliser le filtre numérique à réponse impulsionnelle limitée en tant que filtre de bande de base dans un système de communication mobile réduit la déformation d'onde du signal de bande de base numérique modulé dans une dimension inférieure telle que BPSK, QPSK/DQPSK, GMSK, ainsi que la déformation d'onde du signal de bande de base numérique modulé dans une dimension supérieure telle que 8PSK, 16PSK, 32PSK, 16QAM. Ainsi, des systèmes de communication mobile, en particulier des systèmes de communication mobile haute vitesse, présentent une grande efficacité de spectre de fréquences et une grande capacité, constituant ainsi la base d'un système de télécommunication numérique sans fil fournissant un service de transmission de données haute capacité et haute vitesse.

Abstract: Ein Fahrrad ist mit vielen verschiedenen Lagern und Gelenken ausgestattet ist. Ein Großteil dieser Gelenke sind nicht umlaufend, werden aber im Stand der Technik unnötigerweise als umlauffähige Gelenke mit Wälz- oder Gleitlagerung ausgeführt. Die teilweise gegensätzlichen Anforderungen an Gelenke beim Fahrrad sind: Hohe Steifigkeit bei möglichst geringem Gewicht, Spielfreiheit, niedrige Lagerreibung für optimales Ansprechverhalten, sowie Wartungs- und Verschleißfreiheit. Beim Stand der Technik führt das immer zu Kompromissen mit entsprechenden Nachteilen. Das neue Gelenk soll (bei nicht umlaufenden Lagerungen am Fahrrad) die herkömmlichen Lager ersetzen, mit dem Ziel, die genannten Nachteile zu eliminieren. Das Gelenk (3) besteht aus mehreren biegeelastischen Gelenkzungen (2), welche die beiden Bauteile (1, 1') miteinander verbinden. Jede Gelenkzunge (2) ist an jedem ihrer beiden Enden starr mit einem der beiden Bauteile (1) verbunden. Die Gelenkzungen (2) sind dabei so angeordnet, dass nur eine Drehbewegung um die Drehachse möglich ist, jede Schub- oder Drehbewegung in anderer Richtung wird unterbunden. Das Gelenk (3) eignet sich für alle nicht umlaufenden Lager am Fahrrad, beispielsweise für alle Lager von gefederten Hinterbauten an einem Fahrrad.

Inventor: DOMINKE PETER
IPC: B62D6/00
Filed: 2002-01-22
Abstract: When a vehicle is running, an electronic nominal variable ( delta >VAS<) is formed in the steering system, at least from the position ( delta >LRA<) of an operating element, in order to control the wheel angle ( delta >RA<) of at least one wheel of the vehicle. The maximum wheel angle ( delta >RA<) is thus mechanically defined. The wheel and the operating element can be separated in at least one operating state, and can be interconnected in at least another operating state. In order to be able to provide a buffer for the operating element in the event of a maximum wheel angle ( delta >RA<, max?), the mechanical connection between the wheel and the operating element is created (60) when the wheel angle ( delta >RA,) reaches its mechanical limit ( delta RA, max) in such a way that a buffer is formed for the operating element.

Abstract: 1,139,017. Speech recognition. INTERNATIONAL BUSINESS MACHINES CORP. 15 Sept., 1967 [29 Sept., 1966], No. 42164/67. Heading G4R. [Also in Division H4] In a speech analysis system, a signal representative of the harmonic energy of a speech signal is obtained from the sum of rectified signals each representing a respective harmonic content of the speech signal. Speech is split by filters at 3 having passbands of width 300 hz and centre frequencies as shown, the filter outputs being rectified at 4, passed through low-pass filters (15 hz) at 25 and summed at 29 to give the total spectral energy at 32. The outputs of filters 4 are also passed to 9 where they are summed, band-pass filtered (70 hz to 150 hz viz fundamental) at 13, fullwave rectified at 14 and low-pass filtered (15 hz) at 15, to give the harmonic energy at 16 (voiced sound). The energy signals at 32, 16 are compared at 17 to produce a voiced/unvoiced binary indication at 20d, the gains of the summing amplifiers 10, 30 being appropriately chosen for this purpose.

Abstract: 1,154,129. Speech recognition. INTERNATIONAL BUSINESS MACHINES CORP. 20 Dec., 1967 [29 Dec., 1966], No. 57991/67. Heading G4R. In speech analysing apparatus, harmonics and the fundamental are detected, detection of the latter controlling means providing signals indicating the time of occurrence of each harmonic. A speech waveform is fed to a pre-amplifier PA having automatic gain control 26, the high, middle (viz. 250-3000 c/s.) and low frequencies being routed to a fricative selector FS, harmonic locator HL and envelope peak detector EPD respectively. In the ease of voiced sound, the detector EPD (which responds to the fundamental) starts a scan ring SCR and a time base ring TBR, after delays. The scan ring SCR distributes the pulses from the harmonic locator HL (presence of a particular harmonic being indicated by presence of a pulse at a corresponding time) to integrating pulse shapers (having a threshold) IPS2-IPS8, the digital outputs from which are set into rows 2-8 of a storage matrix SM, at column positions successively selected by the time base ring TBR. On the other hand, in the case of fricative sound, an integrating pulse shaper IPS 1, fed from the fricative selector FS, starts the time base ring TBR, after a delay, to set successive values of the output of IPS1 into row 1 of the storage matrix SM. The harmonic locator HL consists of a peak detector feeding a univibrator (to produce standard pulses). The delays in activation of the rings are to prevent a pulse from the harmonic locator HL representing the fundamental from being used.

Title: Preparation of formaldehyde

Filed: 1969-05-20
Abstract: PREPARATION OF FORMALDEHYDE... Controlling optimum conditions for HCHO preparation from vapourised methanol or vapourised methanol-water solution and air on an Ag catalyst, by a process in which the adjustment of the methanol-water mass flow takes place above the added hot stream mass flow. Industrial yield and residual methanol amount are determined from input mass streams and waste gas concns. Continuously determined adaptive models of the process are used as basis for optimisation and the level of liquid in evaporator is controlled by a level-methanol-water-flow cascade, where the theoretical value of the objective variable "flow" is changed together with the change of the hot stream theoretical value while considering a conversion factor corresponding to the heats of vapourisation. Air is added to reaction gases in amount such that reaction temps. are 500-750 degrees C, depending on Ag catalyst activity.

Title: Wrapping in plastic sheet - with embossed pattern in sheet producing wetlike envelope
IPC: B65B15/04
Filed: 1971-01-15
Abstract: A method for holding objects by a plastic sheet consists of first heating plastic sheet, then imparting to it a surface embossing while hot, then heating it again and wrapping it round the object and producing a vacuum between the sheet and the object; this causes the embossed sheet to envelope the object like a net. Specif. infra-red heating may be used locally, the remainder of the sheet being simultaneously cooled, and rolls, locally wetted with silicone may also be used to form the pattern. A typical application is the protection of one side of a perforated plate by a sheet; wiring connections are then introduced from the other side, and the plastic sheet subsequently removed.

Inventor: SCHROER FRANZ-JOSEF
IPC: B65H45/107

Abstract: As the fabric guide moves in a reciprocating path the pressure pads move in and out of position in an alternating action so that as the fabric is laid, a pad holds it down, the other pad moving out of the fabric guide path. The actions are reversed as the fabric guide returns to lay the next layer. This allows fabric to be laid in a high stack, with the edges accurately aligned to give accurate fabric lengths in each layer.
