Patent EP-0025384-B1 (EP)
IPC: B64B1/00
Filed: 1980-08-28
Granted: 1988-11-17
Abstract: The invention concerns a spheroid container flattened at either pole. The structure is made from gores assembled along their edges. Meridional mono-directional reinforcements are fixed at intervals to the connecting lines of the gores. The gores are made of a material with a low elastic modulus and a high capacity for plastic elongation and the meridional reinforcements from a material with a high elastic modulus. An overpressure inside the structure causes it to take on the shape of a lobed spheroid, flattened at either pole. Application for closed balloons and pressurized containers.

Abstract: A heat exchanger in plants for ventilating dwelling rooms, for example. The heat exchanger (10) is of the recuperative type with two duct systems (11, 12) separated by a plurality of heat-transferring partition walls (16). Supply air and exhaust air are controlled by a valve means (33) to alternate, so that the two air streams are periodically shunted between the two duct systems depending, inter alia, on the outside air temperature and the inside air temperature and humidity. By means of shunting there is avoided, inter alia, condensation and possible frost formation in the heat exchanger simultaneously as the efficiency of the heat exchanger is improved.

Abstract: This invention provides a high speed catadioptric system of F/1.2. The lens system comprises, in accordance with the advance of the light rays, a front lens, a main mirror lens, a counter mirror surfaced to the central portion of the front lens, and a field lens system. The field lens system is composed of the unsilvered central portion of the main mirror lens and additional lenses immediately adjacent to the main mirror lens at its object- and image side. The same glass is used for the front lens and the main mirror lens. This glass is light, cheap and rather resistant to chemical attack. Three preferred embodiments present a rather high state of correction for the wavelength range from 400 nm to 1000 nm, providing a high contrast image with good detectability of poor-contrast objects. Such lens systems, in spite of their good performance, are of rather simple construction bringing about a lower price of manufacture than known systems. The new lenses are useful also for systems used at low light level employing image intensifier tubes of the 1st, 2nd and 3rd generation.

Title: Disque optique en temps reel et procede d'enregistrement et de lecture
IPC: G03C1/72

Granted: 1985-02-06
Abstract: Disque optique en temps reel ayant une couche d'enregistrement deformable a la chaleur (33) qui en vertu de son epaisseur et de ses proprietes optiques, produit un signal de lecture de sortie d'un rapport signal /bruit eleve. Le disque optique de l'invention comprend une couche d'enregistrement (33) ayant une grande capacite de transmission de lumiere d'une longueur d'onde de lecture et qui presente, par rapport a la lumiere de longueur d'onde de lecture, une courbe relative entre le dephasage ((Alpha)) et l'epaisseur (t) caracterisee par une region d'une pente relativement abrupte suivie d'une region de pente relativement douce. L'epaisseur de la couche d'enregistrement est selectionnee a proximite ou dans une plage correspondant a une zone de cette courbe ou l'on trouve une transition entre les pentes forte et douce; ainsi, des diminutions d'epaisseur de la couche d'enregistrement (produites par l'enregistrement de piqures dans la couche d'enregistrement) produisent des changements relativement grands de phase d'une lumiere de lecture incidente, et des accroissements de l'epaisseur de la couche d'enregistrement (produite par exemple par des debrits optiques et des bords de crateres) produisent des changements relativement petits de phase de cette lumiere de lecture. De preference, l'epaisseur et les proprietes optiques de la couche d'enregistrement sont egalement optimales en leur donnant des proprietes de grande absorption a la lumiere de longueurs d'ondes differentes (c'est-a-dire la longueur d'onde de la lumiere utilisee pour enregistrer des informations sur la couche d'enregistrement).

Granted: 1986-12-10
Abstract: A sheet bending machine wherein a sheet of metal is fixed between a clamping beam and a lower beam mounted with interchangeable folding rails and wherein the bending is performed by a bending beam being swung against the projecting part of the sheet metal. The interchangeable folding rails have markings, for example, protrusions or recesses on the rear edge which cooperate with a set of members for establishment of a steering code which determines the maximum permissible bending angle for the folding rail. The code may be in the nature of a series of contacts which are opened or closed, dependent on the folding rail being used, having a recess opposite them or not. The state of the contacts may, for example, be sensed by a cam disc which curves synchronically with the swing movement of the bending beam and successively opens the contacts which are connected in parallel above them, so that a current circuit is switched when both corresponding pair of contacts are opened.

Title: Apparatus and method for locally heating conveyed glass sheets
IPC: C03B23/023
Filed: 1983-08-15
Granted: 1987-01-28
Abstract: An improved apparatus including a localized heater that moves along the direction of conveyance with conveyed glass sheets to provide localized heating of a portion of each glass sheet to be bent without heating the rest of the glass sheet prior to its subsequent treatment. This invention is especially suitable for locally heating designated portions of glass sheets as they are heated while being conveyed through a furnace on a horizontal roller conveyor where the designated portion of glass sheets are to be formed with bends having relatively short radii of curvature at a bending station. The apparatus includes a pair of elongated localized gas heaters, each of which is positioned above the portion of the glass sheet which requires significant bending. These heaters are mounted on a carriage driven by a drive mechanism. The drive mechanism causes the carriage to move along a path parallel to the path of glass sheet conveyance to allow the heaters to continuously heat the designated portions of the glass sheet between an upstream position and a downstream position of the carriage. After the carriage reaches its downstream position, the drive mechanism causes the carriage to return to its upstream position in preparation for another cycle.

Abstract: Flow control of data packets through a packet switching network (20) to reduce congestion is controlled by an adaptive preferential permit packet (APP) processing from an originating data terminal (10) through each packet switch node of the network to a destination data terminal (11). APP requires less buffer storage capacity at each switch node, and enables data packets to enter the network only when there is a permit packet indication that the data packets are likely to reach, and be accepted by, their destination. The permit packet is sent node to node (16-19, 25, 28) prior to a transmission of a bulk of data packets. Each node is equipped to queue buffer (12-15, 21-24) a permit packet on a preferential basis ahead of data packets. The node discards the permit packet if the number of packets awaiting transmission from that node exceeds a prescribed threshold. This is throttling process, since the originating port times out and resends a permit packing if a permit-return packet is not received within a predetermined time. Permit-return packet processing, adaptive time-out controls, and preferential treatment of permit packets are disclosed.
