Title: Process for the treatment of rolled steel for increasing corrosion resistance
IPC: B21B45/08
Filed: 1988-08-26
Granted: 1991-12-18
Abstract: To apply a coating of a non-ferrous metal such as, for example, zinc to the surface of rolled steel to increase the corrosion resistance, it is proposed to descale the rolled steel continuously downstream of the rolling step from the rolling pass by applying pressurised water and, immediately after descaling and while preventing a renewed formation of scale, to cool it by means of water rapidly to a temperature suitable for hot application of the coating and finally to apply the coating. One of the advantages of the invention is that, both for descaling and for preventing the renewed formation of scale and for simultaneous cooling, only a single medium, namely water, is used, and the cooling can be controlled in such a way that the rolling pass can be exploited in an optimised manner for the coating. The result is that all process steps or treatment processes can proceed as a continuous extension of the rolling step, i.e. at rolling speed, so that the finished coated end product leaves the production line analogously to a normal, not aftertreated rolled product.

Abstract: Le système de détection de proximité et le procédé de traitement de signaux décrits servent à détecter des objets cibles à partir d'un véhicule mobile (8), tout en assurant une protection contre la détection de fausses cibles due à la présence de brouillard, de nuages ou d'autres aérosols. Un ou plusieurs détecteurs de cible (202) sont disposés en alternance près d'un ou de plusieurs détecteurs de surveillance (201; 203), de façon à placer les contours des champs de vision à proximité immédiate. Un faisceau de rayons laser (B) alignés par collimation est projeté depuis le véhicule par un émetteur (30) le long d'un axe qui coupe avec un angle les champs de vision adjacents, définissant ainsi des régions actives dans lesquelles le faisceau sera réfléchi par des objets. Les signaux produits par l'une et/ou l'autre des réflexions du faisceau sur un détecteur de cible sont rendus positifs, alors que les signaux produits par l'une et/ou l'autre réflexion du faisceau sur un détecteur de surveillance sont rendus négatifs par rapport à une référence seuil. Les signaux sont totalisés dans un amplificateur de différentiel et le signal qui en résulte est présenté à un comparateur numérique.

Abstract: A ferroelectric liquid crystal device (6) has a first state (TX1) of maximum transmission, a second state (TX2) of minimum transmission and a value of voltage pulse width (tS) and voltage pulse height (VS) sufficient for a switching pulse (20, 26, 28) to switch the cell from the first state (TX1) to the second state (TX2) or vice versa. A method of controlling the transmission of electromagnetic radiation through the ferroelectric liquid crystal device comprises the step of applying, for a time period greater than said value of pulse width (tS), a plurality of consecutive controlling pulses (22, 24, 27, 28a, 29a) of one polarity. Each controlling pulse is itself of insufficient pulse height and pulse width to switch the cell from the first state (TX1) to the second state (TX2) or vice versa.

Title: Process for switching signals into or out of subdomains of the supplementary signals of transmission modules of a synchronous digital signal hierarchy
IPC: H04J3/08
Filed: 1989-06-02
Granted: 1993-09-15
Abstract: Process for switching out signals from at least one subdomain of the supplementary signals and for switching signals into at least one subdomain of the supplementary signals of transmission modules of a synchronous digital-signal hierarchy according to CCITT draft recommendations G.70X, G.70Y and G.70Z. This is achieved, for switching out, in that in a demultiplex and expanding device (1a), a subdomain of the supplementary signals is switched out of the transmission module (STM-4) and is expanded over a time interval within the frame. The expanded signal is, for example, separated into the supplementary signals (TB-STM-1) of the chosen subdomain, which are allocated to the transmission modules (STM-4) of the lowest hierarchical level of the transmission module. For switching in, the stages of the process are followed in reverse order and in the opposite sense. Said supplementary signals (TB-STM-1) are fed into the lines (L1-L4) of the bus (B). The pilot signals (T) generated in the demultiplex and expanding devices (1a) or externally entered are transmitted in a sub-bus (SL). After addresses (A) have been added, bytes (D) or byte groups (D) can be taken from the bus (B) and further processed through customer interfaces (2a, 3a). Said process is suitable for synchronous digital-signal hierarchies such as NNI (Network Node Interface).

Abstract: A phase detector for a multi-channel PSK receiver is provided with a plurality of phase channels (X, Y). Each of the phase channels has its own comparator (56, 57) coupled to an electronic switch (58, 63) for producing signals which are the products of the analog data inputs on the phase channels. The outputs from the electronic switches (58, 63) are connected to positive (61) and negative (60) summing circuits and the output of the positive and negative summing circuits are connected to the positive (72) and negative (71) inputs of a differential amplifier (68) which produce a sum of the difference of the absolute value of the analog data inputs which is employed as an error voltage signal to control the frequency of a voltage controlled oscillator (not shown) in a multi-channel PSK receiver. By eliminating convention analog multipliers in the phase detector, the phase detector is capable of generating error voltage signals from analog data input signals having data rates as high as 5 gigabytes per second.
