Abstract: A stereoscopic filmstrip (F) and associated viewer (20) are described. The filmstrip (F) is made from standard 35 mm film by a method which allows copies to be made using standard film copy equipment. Image frames are arranged on the strip in two longitudinal rows (R,R 2 ) stereo- scopically paired images (e. g. 1L, 1R) being in one of the longitudinal rows (R,) and one of the images being spaced along the row, in relation to its paired image, by four intervening frames (e. g. 23R, 2L, 24R, 3L). 
     The viewer illuminates the filmstrip by reflection of incident light by mirror (120); a mask (94) in front of the filmstrip has apertures (96) to allow viewing of paired stereoscopic images (e. g. 1L, 1R) only. A filmstrip transport mechanism (30) in the viewer is a ratchet-driven wheel turnable stepwise by an amount corresponding to the spacing on the filmstrip (F) between a first pair of images (1L, 1R) and a successive pair of images (2L, 2R).

Abstract: In a sodium sulphur cell, the cathodic reactant comprising sulphur and sodium polysulphides is highly corrosive and of poor electrical conductivity. It is known to put carbon material, e.g. a graphite felt in this reactant to form a conductive path to a metal current collector which must be protected against corrosion in any cell having a long life. The present invention is directed to an improved current collector. 
     Figure 4 illustrates an embodiment in which the current collector comprises an aluminium rod or tube 25 surrounded or partially surrounded by a sheath 26 of a metal, such as a nickel alloy, resistant to corrosive attack. The aluminium rod or tube 25, where it is exposed, becomes coated with an oxide and/or sulphide layer which is non conductive. The sheath is welded at 28 through this layerto provide electrical conductivity and may have radially extending fins 27.

Abstract: Le convertisseur de couple hydrodynamique comprend des aubes pivotantes (9) en un materiau elastique, qui sont disposees en amont d'une zone, en particulier d'une roue fixe. Les aubes peuvent pivoter autour d'un axe (11) pour etre amenees, par le courant de liquide, a s'orienter selon la direction de ce courant. Chacune d'elles est disposee entre les deux aubes fixes suivantes (10) de facon telle que son angle de pivotement soit limite dans les deux directions par ces deux aubes fixes (10). Cette limitation de l'angle de pivotement a pour consequence que, sous certaines conditions de fonctionnement du convertisseur, les aubes forment un angle avec la direction du courant de liquide. Le materiau elastique des aubes cede a la pression du liquide, c'est-a-dire que les aubes se deforment et orientent leurs bords dans la direction du courant. Par un choix judicieux des parametres, les pertes peuvent etre reduites au minimum.

Abstract: The speed of a flowing mediums is measured by determining the transit time of sound pulses transmitted alternately in opposite directions between first and second transmitterreceivers 23, 24 spaced apart in the direction of flow. A processing circuit 18, 19, 20 evaluates the speed of flow from the difference between the transit time in the two directions. The transit times in the two directions are measured by separate but identical first and second pulse circuits 11, 11'. Each pulse circuit includes a variable frequency generator 13 the frequency of which is so regulated by the transmitted pulse from the pulse generator 12 and the pulse E received from the associated transmitter-receiver that the reciprocal of its frequency is equal to the transit time in the associated direction. Delay circuitry 21 is able to delay the trigger pulse applied to the frequency generator 13 from the pulse generator 12 so as to take account of transit time errors in the apparatus.

Abstract: A colour cathode ray tube display apparatus is provided with compensation for errors due to interfering magnetic fields in which a deflection yoke causes the electron beams to raster scan across the tube, a convergence assembly on the neck of the CRT adjusting the beam convergence. Errors in the waveforms supplied to the radial convergence assembly are due to high frequency magnetic field coupling between the yoke and the convergence assembly via the internal magnetic structure (7) of the CRT. 
     A compensating coil (11) placed adjacent the affected convergence coil unit (12, 16) supplies compensating current through resistor (20) to the amplifier (15) driving that convergence coil unit, thus avoiding a fringe on the left-hand side of the screen. 
     Alternatively, compensating current can be derived from the line flyback pulse or the logic signal initiating line flyback.

Abstract: Von einer Lichtquelle (1) ausgehendes Licht gelangt über ein Linsensystem (2,3) und ein erstes Barrensystem (4) auf die Steuerschicht eines Steuerelements (SE), wird dort entsprechend deren lokalen Deformationen reflektiert und gebeugt und denn über einen Hohlspiegel (6), ein zweites Barrensystem (7) und ein weiteres Linsensystem (8) auf eine Projektionsfläche (9) geleitet. Das zu verstärkende Bild (10) wird mittels eines Linsensystems (12) auf eine lichtelektrische Leiterschicht im Steuerelement (SE) abgebildet. Die Steuerschicht ist eine Gel-Schicht und befindet sich zwischen zwei Elektroden in einem elektrischen Wechselfeld, welches durch die lichtelektrische Leiterschicht beeinflussbar ist. Die der lichtelektrischen Leiterschicht benachbarte Elektrode ist als Streifenraster ausgebildet, wobei alle Streifen bezüglich der anderen Elektrode auf demselben Potential liegen. Das zu verstärkende Bild wird auf die lichtelektrische Leiterschicht in gerasteter Form aufbelichtet, wobei das Raster orthogonal zum Elektrodenraster verläuft. Letzteres ist orthogonal zu den Barren ausgerichtet. Die optische Rasterung des Bilds erfolgt durch ein Spiegelraster, durch ein Absorptionsraster auf der Oberfläche einer Faserplatte oder dadurch, dass die lichtelektrische Leiterschicht selbst aus einzelnen Streifen besteht. Ferner kann natürlich auch das zu verstärkende Bild selbst gerastert leuchten bzw. gerastert beleuchtet sein. Das System weist eine sehr geringe Grunddeformation der Steuerschicht auf und besitzt damit eine relativ hohe Empfindlichkeit und einen hohen Wirkungsgrad.
