Abstract: Water/air coolers are fastened to date via steel side pieces which overreach embrace the water boxes laterally. The new side pieces are to be more cost-effective and less susceptible to corrosion. This is rendered possible by a one-piece plastic side piece (1), which forms corner connections, which act in a hinge-like fashion with the water boxes, via pins (4, 4A; 5, 5A), which engage in recesses (8, 8A; 9, 9A). The plastic material is not susceptible to corrosion, and furthermore a plastic lateral part produced by injection moulding is very cost-effective. The water/air cooler can be used in commercial vehicles. <IMAGE>

Abstract: A spring clutch assembly is disclosed having an input clutch member (3), an output clutch member (4), coaxial there­with, and further having a clutch spring (8) disposed partially in each clutch member, the spring placed on an arbor (12) having a shoulder (20) at the input end thereof. The arbor is fixed to the input member by a collet fit and extends through the output member into a housing (2) where it is rotatively supported by bearings (21). The input member is also supported rotatively by bearings (6) which may further include a squeeze film damper (27) to control the assembly spring rate and thereby minimize vibrations by traversing a rigid body mode vibration at low speed. Such spring clutch assemblies are par­ticularly useful in high RPM environments where vibrations must be held to a minimum. A clutch spring is also disclosed, having a very fine axial cut across a cross-over coil (41) and transition coils (54) disposed between the teaser coils (52) and the central coils (53). The transition coils form a gradual ramp (58) to distribute stresses over several coils, preventing spring failure.

Abstract: In a teletext decoder circuit the character generator supplies picture elements at a rate of nominally approximately 6 MHz under the control of display pulses occurring at the same rate. These display pulses are derived from reference clock pulses which occur at a rate which is not a rational multiple of 6 MHz. The character generator comprises a generator circuit which receives the reference clock pulses and selects, from each series of N reference clock pulses, as many pulses as correspond to the number of horizontal picture elements constituting a character, whilst the time interval of N reference clock pulses corresponds to the desired width of the characters to be displayed. The character generator supplies picture elements of distinct length, whilst the length of a picture element is dependent on the ordinal number of this picture element in the character.

Abstract: Procédés de production d'hologrammes à partir d'un modèle informatique d'un objet quelconque (30), utilisant des moyens optiques et numériqus combinés. On spécifie un modèle d'éclairage et les propriétés de dispersion de la lumière de l'objet (30). L'hologramme (50) est synthétisé à partir d'un ensemble d'éléments holographiques plus petits (52, 54). Chaque élément individuel (52, 54) supporte un champ de vision de l'objet. Les rayons lumineux provenant de l'objet situé dans le champ de vision et le long des lignes de vision sont échantillonnés par l'ordinateur (60). La densité d'échantillonnage ne devrait pas dépasser la limite de résolution déterminée par la taille de l'élément holographique (50). Chaque rayon lumineux est spécifié par une direction et par une fonction de l'amplitude. On peut obtenir l'élément holographique (52, 54) à partir d'une transformée de Fourier des rayons échantillonnés en utilisant une radiation cohérente. On provoque ensuite l'interférence des rayons de lumière cohérente reproduits avec un faisceau cohérent de référence, de manière à former l'élément holographique (52, 54). Dans une variante, la frange d'interférence est calculée directement par l'ordinateur (60) et imprimée pour former l'élément holographique (52, 54).

√ M  =  a  +  b [(σ₁ + σ₂) + 3(σ₁ - σ₂) cos 2ϑ], 
in which σ₁ is a principal stress, σ₂ is the principal stress perpendi­cular to σ₁, ϑ is the angle between σ₁ and the direction of measure­ment of µ,  a  is the value of √ M  in a stress-free state and  b  is the stress sensitivity,  a  and  b  being determined separately.

Abstract: Cassette (3) for a device for continuous casting of molten metal between two parallel rolls (2), comprising a casing (4) which is open on one of its sides, containing a plate (5) of refractory material which can be preheated before casting of the molten metal; the refractory plate (5) is preformed so as to reserve a free space (8) between its periphery and the wall (4b) of the casing (4), and this cassette is equipped with means (9, 11) for fastening and clamping the plate (5), with elastic antagonistic action permitting free expansion in the casing (4) of the plate (5) during its heating up. The free expansion of the refractory (5) prevents any bulging or bending of the latter and of the assembly of the cassette (3), and thus ensures maintenance of sufficient leaktightness to avoid any risk of infiltrations of molten metal between the front faces (2a) of the rolls (2) and the refractory plate (5). <IMAGE>
