Title: Window glazing with solar heat collector - comprising-flat photocells near transparent, pref. PMMA, plastic sheet connected to electrical circuit
IPC: H01L31/055
Filed: 1982-03-31
Abstract: A window comprises a frame (6) and a glazing element (2) mounted in the frame (6). The element (2) comprises a rigid sheet (2) of transparent plastics in which is homogeneously dispersed a series of luminescent or phosphorescent materials forming a luminous cascade, the absorption band of which covers a very large part of solar radiation wavelengths and the emission band of which covers a predetermined narrow band. The element (2) comprises, in the vicinity of at least 2 of its opposite edges, a series of flat photocells (3) the best operating range of which is situated in the narrow emission band of the luminous cascade. The lower part (8) of the frame (6) has a relatively large width to shield the photocells while its outer part (9) is of reduced width to expose the element (2). Means are provided for connecting the cells (3) to an electrical circuit (5) located outside the frame. Used for trapping solar heat. The design results in high yield and the cells are completely shielded from view by the frame (2) while the transparent sheet (2) is colourless and does not look different from a conventional glass.

Title: Variable amplitude DC analog voltage isolating circuit - is responsive to duration of periodic variable pulse-width input signal and uses flyback transformer or opto-electronics isolator
Inventor: BEDARD JAMES FREDERICK
IPC: G08C19/22
Filed: 1982-05-18
Abstract: The circuit includes a fly-back type transformer having a primary winding connected to a controlled waveform generator providing the variable pulse-width periodic waveform. The voltage across a secondary winding of the transformer is rectified to provide a unipolar D.C. analog voltage to a load. In another embodiment an optoelectronic isolator receives the controlled waveform generator output to control the resistance between a source of operating potential and a filter capacitor. A D.C. analog voltage appears across the capacitor with magnitude responsive to the duty cycle of the variable pulse-width-modulated signal. For noise-rejection purposes a pulse-width-modulated signal is used for transmission of load control information, via a medium (25), between a central facility (30) and each control circuit-ballast-lamp combination.

Title: Current supply for electric machines - using sintered metal graphite power mixt. for slip rings
Inventor: DREYER MANFRED
IPC: H01R39/08
Filed: 1982-05-28
Abstract: A current conduction device for electrical machines, specially for use as a slip ring or a collector, consists of at least one electrically conductive sliding element on the periphery or face of a cylindrical insulating carrier which forms the running track for a brush. The sliding element is made of a mixture of metal and graphite, the predominant share represented by copper or bronze powder. This has a higher mechanical strength than a graphite slide ring and permits the application of a press fit. It is easier to solder and requires no special lugs or copper plated areas.

Title: Aircraft drag indicator - has tube contg. liq. and ball where tube internal contour has flat sides to reduce ball-wall friction
Inventor: BLAS ROBERT
IPC: G01C9/10
Filed: 1982-06-11
Abstract: The toroidal tube (T) is filled with a liq. such as toluene or white spirit and containing a ball (B) made of tungsten carbide, uranium or other material heavier than steel. There is a gap between the ball and the internal wall of the tube. The internal contour of the tube cross section is polygonal having flat or convex sides at least in the zone of eventual contact of these sides with the ball. The cross section may thus be triangular, square, or have more than four sides. Alternatively, the cross section may be circular with bosses creating local convex zones. For a square cross-section, the eventual contact-points (x,y) of the ball are on two adjacent sides. These two discrete points offer a much lower friction than that which would be produced with a tube of circular internal cross-section, thus providing an improvement over existing aircraft drag indicators.

Patent FR-2522357-A1 (FR)
IPC: E06B9/165
Filed: 1983-02-25
Abstract: The invention relates to a roller-blind bar intended especially for roller blinds and rolling doors and composed of a metal bar outer part curved towards the outside of the bar and of a plastic bar inner part in catch connection with the bar outer part on the rear side of the latter. The bar inner part limits with the bar outer part an inner space. Articulation parts extend on the longitudinal edges of the roller-blind bar. The articulation parts of two successive roller-blind bars engage in one another and form an articulated connection. The bar outer part is equipped with the articulation part both on its upper longitudinal edge and on its lower longitudinal edge. Furthermore, the bar outer part is equipped on its upper and lower longitudinal edges with a projection which faces away from the articulation part and which serves for the catch connection with the bar inner part. The bar inner part is assigned elastically flexible webs projecting transversely from it. When the two bar parts are in the connected state, these webs bear against the bar outer part and subdivide the bar inner space into chambers separated from one another and therefore preventing air circulation.
