Abstract: Un debimetre a turbine (1) du type dans lequel un rotor a pales (14, 53) est en rotation par l'ecoulement d'un fluide autour d'un axe se trouvant dans le sens general de l'ecoulement. La longueur des pales (13, 54) ne depasse pas 0,3 fois le rayon aux extremites des pales, chaque pale etant torsadee sur sa longueur proportionnellement a son rayon. La torsion maximum est telle qu'en aucun point l'angle par rapport a l'axe de rotation n'est superieur a 15 . Aucun passage visible n'existe au travers de la zone des pales pour le fluide. Un transducteur de force (56, 57, 63) est monte dans le passage d'ecoulement du fluide pour permettre une mesure de la force d'impulsion a donner pour que, sur la base d'une mesure de la vitesse de rotation du rotor, il soit possible de deduire le debit massique du fluide.

Abstract: A multi-trace element fertilizer which contains magnesium as a further nutrient and in which the complex-forming trace elements are present in the form of anionic chelates with one or more N-carboxyalkylaminoacids is prepared by a process wherein the N-carboxyalkylaminoacids are reacted, in the presence of water, with the trace elements or trace element compounds in a molar ratio of N-carboxyalkylaminoacids to trace elements or trace element compounds of not less than 0.8:1, at least 20% by weight of the trace element compounds being oxides, hydroxides and/or carbonates. At the same time, or subsequently, the pH of the solution is brought to 3.5-6 by adding a member selected from the group consisting of magnesium oxide, hydroxide and carbonate. A maximum of 50 equivalent percent of the magnesium compound may however be replaced by a member selected from the group consisting of alkali metal oxides, hydroxides and carbonates and ammonia.

Abstract: An improved information recording medium having a special nitrated dye recording layer (35). Information can be recorded in the medium (11) by scanning the recording layer with an intensity-modulated beam of light (13), to selectively heat portions of the layer and thereby cause corresponding minute explosions in it, yielding a sequence of spaced microscopic pits (15) representative of the information. The exploded material contains primarily non-condensable gases so that very little, if any, non-gaseous residue is deposited on surrounding portions of the medium, and the information is thereby recorded with an improved signal-to-noise ratio.

Abstract: Procede de modification des caracteristiques de surface d'un substrat polymere preforme pour lui donner des caracteristiques hydrophiles, hydrophobes ou autres caracteristiques desirees, par peroxydation de la surface du substrat puis en permettant aux sites actifs le long des chaines polymeres de generer des radicaux libres qui induisent une polymerisation par greffage d'un monomere ethylenique approprie (ou autres composes non satures a liaison ethylenique) sur la surface du substrat. Une telle copolymerisation par greffage s'effectue en presence d'ions metalliques de valence variable dans un etat reduit dans des conditions acides, avec des temps de reaction selectionnes et a des temperatures relativement basses, et en presence d'ions squarate (dicetocyclobutenediol) pour controler les caracteristiques physiques de la greffe en surface et pour ramener les ions metalliques a leur etat de valence la plus basse sans pour autant produire des sous-produits nuisibles.

Abstract: A bar code reader (17) reads allophonic code from a bar code format into a speech producing system (11, 12, 13, 14, 15) to provide speech corresponding to the allophonic code. A bar code format includes a synchronization bar, followed by a barless space, one half the width of the synchronization bar. The barless one-half space is followed by a plurality of data bar spaces, each equal in width to the synchronization space. By counting the time taken to traverse the synchronization space, and by then immediately thereafter counting the counter down to zero, the mid-point of the first data bar space is sampled because of the intervening one-half width barless space. Following the last data bar space, is a full barless space to provide time for initialization to read the next set of bars. In this preferred embodiment, allophonic code is read into a speech producing system (11, 12, 13, 14, 15) whose controller (11) controls the operation of the optical reader (17). Also in this preferred embodiment, the bars are printed over or near associated text (18) and are transparent and reactant to infrared.

Abstract: In order to form safety markings at a planar card made of a plastics material, which card may be used, for instance, as credit card, this card is built up from at least two parts. The inner border area between these two parts comprises a relief-like structure which is the carrier of the safety marking. In order to generate a watermark-like effect the upper part is made of a opaque plastic material and the other part is made of a transparent plastics material. When viewing through this card the areas of the opaque layer having the largest thickness appear as darker areas, whereby when viewing the same way the areas having a smaller thickness show a certain brightness. After being embossed the two parts of the thermoplastic material are joined to each other such that they cannot be separated such that no access from the outside is possible to this safety marking. Accordingly, an additional safety factor is arrived at in cards which can be used as money substrate, identification means or a license for any kind of access.

Abstract: A differential drive arrangement distributes driving torque solely by way of viscous fluid coupling means. in one arrangement, in a motor vehicle drive transmission, a crown wheel is mounted co-axially on the housing of a coupling means from which nearside and offside half-shafts extend driven by separate sets of 'inner' annular plates interleaved with those of an 'outer' set of annular plates driven by the housing. In another arrangement, two separate viscous fluid couplings are used, the housings being driven by a common crown wheel. in each case, there is no conventional differential gear. The differential drive arrangement may be for transient four-wheel-drive where one pair of road wheels is positively driven by a conventional differential gear; or the differential drive arrangement may be for 'continuous' duty.
