Title: Plastics solar heat collector - is entirely of materials in common use, pref. black polymethacrylate
IPC: F24S10/50
Filed: 1980-08-11
Abstract: The solar heat collector is constructed entirely of plastic in common use, pref. black polymethacrylate with roughened surfaces, being used. The heat accumulated in a plate-type component can be yielded up to circulating water flowing over one of its faces and through a very narrow gap. The water can be arranged to flow between one wall accumulating heat and a second one preventing this heat from being dissipated to the collector assembly. A space can be formed between a transparent wall and the heat- accumulator plate, having a greenhouse effect collecting long- range infra-red rays, and increasing the overall efficiency.

Title: Circuit permettant de commander de facon symetrique le gain d'un amplificateur differentiel
Inventor: MARWOOD LEOPOLD ALBERT
IPC: H03G3/10
Filed: 1981-01-15
Abstract: L'invention concerne un circuit permettant de commander le gain d'un amplificateur différentiel de façon symétrique. Un circuit de commande comportant un premier et un deuxième transistor identiques 52, 50 connectés entre des points de potentiel d'utilisation (+ 8,2 V, potentiel de la terre) crée une première et une deuxième tension de commande d'amplitude prescrite aux sorties de collecteur des transistors 50, 52. Le premier transistor 52 est polarisé de façon à produire la première tension de commande à un niveau fixe en relation avec la polarisation de commande de gain de l'amplificateur. La deuxième tension de commande varie symétriquement par rapport à la première en fonction du réglage d'un potentiomètre 65 couplé à un circuit de polarisation du deuxième transistor. Le potentiomètre est directement connecté entre les points de potentiel d'utilisation (+ 11,2 V, potentiel de la terre) de façon que les tensions de commande soient égales pour sa valeur de réglage centrale.

Title: Inflatable lightweight radiant energy converter - uses inflatable volume with translucent face and metallised rear panel to reflect radiation onto photovoltaic conversion devices
IPC: F24S23/71
Filed: 1981-05-11
Abstract: The radiant energy convertor uses an inflatable structure with a transparent face and a reflective rear wall to provide a lightweight collector, for earth mounted or aerial useage, which does not require extensive structures for accurate reflector location and stability. The collector uses a flexible material to form a closed volume with convex front and rear faces when the volume is inflated. The face is manufactured from a translucent material, while the rear has a metallised layer which reflects incident radiation onto an array of photovoltaic cells or heat exchanger tubes supported on tubes attached to the mounting point of the convertor. The structure possesses a transparent dome of which the base is covered with a reflective layer e.g. of silver or aluminium.

Title: Containers for storage and transport of nuclear fuels - comprising tube and sheath sealed together with a thermosetting binder
Inventor: KERJEAN JOEL
IPC: G21F5/008
Filed: 1981-09-23
Abstract: Containers, for storage and transport of irradiated nuclear fuels, the walls of which consist on the inside of a central tube, and on the outside of a sheath, each being designed to ensure bath biological protection against ionising radiation and evacuation of heat produced by the fuel, are mfd. by leaving an annular space between the two and filling this space with an appropriate thermal binder, taking account of the max. temps. which have to be considered. Process avoids the need to form a mechanical contact between the tube and the sheath.

Title: Aiding crystallisation of low solubility materials - using carrier gases to remove heat from soln. followed by recycling
Inventor: HADAMOVSKY EUGEN
IPC: C07C51/00
Filed: 1981-09-29
Abstract: Materials dissolved up to satn. level in a solvent wherein they are difficult to dissolve in normal pressure and temp. conditions, esp. terephthalic acid in water, acetic acid, methanol or a mixt. of two of these, are crystallised by removal of heat from the soln. by passing over the soln. a dried carrier gas which becomes charged with solvent vapour. The gas is then cooled, solvent is removed by condensation, absorption or adsorption, the gas is reheated and fed back into the soln. The gas is initially hotter than the soln. and is introduced below the liq. surface. The vapour pressure difference between the soln. at its entry point and in the container is 0-100 (3-60)bar. The appts. is also claimed. Suitable carrier gases include air, N, H, CO2 and inert gases. Applicable to the basic crystallising unit types with mixed or classified suspensions and mixed or classified prod. removal. The units are of moderate height, undesirably small crystals are not produced, and contamination by by-prods. is reduced.

Title: Taking successive urine samples for bacteriological investigation - with automatic separation of flow into receiving vessels for transportation
IPC: A61B10/00
Filed: 1981-10-14
Abstract: The arrangement, for taking separate successive samples of urine from a patient for subsequent laboratory analysis in respect of bacterial content etc., separates urine flow into three separate sections ready for transportation to the laboratory. A fitment (1) with a sealing strip (2) is attached to the seated patient, the fitment having an outlet (1a) for urine flow, which is connected to a rigid branched connecting piece (3). Urine first flows into a flexible shaped tube (4) with a free end whose top is sealed with wadding (5) and is physically higher than the rest of the device. When the U-shaped tube is so full that the level of urine is above the branch (3c) of the rigid connecting piece, flow proceeds down a vertical tube (6) with a U-shaped end into a spherical container (7), which has a breather tube (8). When the spherical container is full, the U-shaped end piece of the vertical tube acts as the holder for the third sect-on of the urine sample.

The matrix printer (11) is mounted on a carriage that runs on guides (121). A motor drive unit (24) allows the carriage to be moved horizontally. A combination of vertical and horizontal motions allows the characters to be reproduced.
Patent FR-2505177-A1 (FR)
Inventor: BRUDERMANN UWE
IPC: A61G5/00
Filed: 1982-05-06
Abstract: Chassis for wheelchairs with two side frames on which the front and rear wheels are rotatable and the front or rear wheels are at the same time mounted so as to be steerable. For achievement of a driving behaviour corresponding to the driving behaviour of a chassis with single-wheel suspension, the invention proposes that the two side frames (1, 2) be connected to one another by at least three connecting rods (3, 3', 5), two of which (3, 3') are arranged crosswise, in such a manner that they are each only movable relative to one another approximately in their planes, the connecting rods each being connected to the side frames in such a way that at least one of the connecting rods lies in a plane other than the remaining rods. A resilient relative movement between the two lateral frames (1, 2) is achieved by the intrinsic elasticity of the connecting rods (3, 3', 5) and/or a resilient mounting of the connecting rods on the side frames (1, 2).

Title: Fabric advance
Inventor: THOMAS ANDRE
IPC: D06B19/00
Filed: 1982-08-25
Abstract: A rotor with a central core is fitted with outer bars extending outwards. Soft sections, placed together, form the outer edges of the bars. Specifically the bars are at an angle or parallel to the axis of the rotor. Each bar is composed of a body and a carrier with a U-shaped cross section mounted to the rotor, made of two sections of which one is for the assembly and removal of the body of the bar which ranges out beyond the carrier. The rear edge, in the direction of rotor rotation, is bent back. Acting with the rotor assembly is a further rotor and guide surface so that both rotors have a synchronised rotation, with opposite directions giving a phased advance action. The mechanism gives a rapid and positive advance action on fabrics, particularly in a dyeing process, without allowing the material to slip.
