Abstract: Procédé et appareil pour créer des images cinématographiques haute définition, impliquant l'utilisation de plusieurs filtres, capables chacun de transmettre de la lumière dans une bande différente de longueurs d'ondes, pour constituer plusieurs composantes d'images superposées sur la pellicule cinématographique pendant une seule période d'image. Une opération de filtrage similaire est effectuée lorsque le film est projeté pour constituer l'image couleur originale. Ainsi, si deux filtres sont utilisés à chaque étape, on peut obtenir deux fois la cadence d'images normale tout en utilisant néanmoins une caméra et un projecteur fonctionnant à la vitesse normale.

Abstract: A primary brake means operated by either one of a hand-operated means (L) and a foot-operated means (P) is mounted on one of the front (W3) and rear (W r ) wheels, and a secondary brake means operated in response to the operation of the primary brake means is mounted on the other of the front (W3) and rear wheels (W r ). Consequently, it is possible to provide a braking-force distribution for the front and rear wheels with a predetermined common characteristic, leading to an improved operational feeling. 
     In addition, a braking-force control means (C v ) is provided for controlling the distribution of a braking force to the front (Wf) and rear (W r ) wheels in accordance with the operating forces of a first input means (M c1 ) operated by the hand-operated element (L) and a second input means (M c2 ) operated by the foot-operated element (P), so that an ideal distribution characteristic is fallen within a region located between a first braking-force distribution characteristic for the front and rear wheels by the hand-operated element (L) and a second braking-force distribution characteristic for the front and rear wheels by the foot-operated element (P), such region being a braking-force distribution characteristic region at a time when the hand- and foot-operated elements (L,P) are operated simultaneously. Consequently, a braking characteristic close to an ideal distribution characteristic can be obtained by operations by a hand and a foot, leading to an improved operational feeling.

Abstract: An acousto-optic modulator (20) for use in an optical time domain reflectometer to test multimode optical fibers (26) has an active material, such as As-Se-Ge or As₂S₃ glass, that has a high figure of merit with a low insertion loss. The transducer (42) for the modulator is configured to have a height that encompasses the multimode beam diameter at the optical wavelength, and a length that is consistent with a theoretical lower limit that is a function of the acoustic and optical wavelengths. Sufficient RF power is applied to the modulator to produce an angular efficiency, or optical throughput, that is sufficient to meet the specifications for the optical time domain reflectometer. Further dead zone correction for the optical time domain reflectometer is obtained by deriving a transient response signal for the optical time domain reflectometer as a function of a measured output electrical signal in response to a known input optical signal, and subtracting the transient response signal from an output electrical signal obtained in response to an unknown input optical signal to derive a corrected measured output electrical signal.

Abstract: 1. A commutator having hooks integrally formed on the winding-side end of each commutator laminate. 2.1 During winding of rotors having hook commutators with relatively large wire cross-sections (parallel wires) there are in each case three wires under two commutator hooks when known winding methods are used. This leads to welding problems. The new commutator is intended to facilitate winding of rotors with relatively large wire cross-sections without welding problems occurring. 2.2 The commutator has at least one commutator laminate (16) on which two hooks (17, 17') are integrally formed. <IMAGE>

Abstract: 2.1 The transporter in question is characterised in its field as a towing vehicle. It is therefore provided with a raisable and extendable platform so that a passenger vehicle can be moved up onto it or down onto it. 2.2 In order to eliminate distortion of the auxiliary frame (13) when it is stressed on one side, the longitudinal profile members of the platform (11) are guided exclusively longitudinally displaceably on the longitudinal spars of the auxiliary frame (13) and are secured in a positively locking manner against any displacement transversely with respect to the longitudinal axis because the longitudinal profile members of the platform (11) consist of profiles with a high section modulus with respect to the two bending axes. The longitudinal profile members of the platform (11) can be double-T profile members (25, 16), circular tubes (33, 15, 16) or even closed or open triangular profiles (34). 2.3 The transporter is suitable for towing away passenger vehicles damaged in accidents or even for transporting a plurality of passenger vehicles. <IMAGE>

     The operative connections between the components of the delivery system ensures that the valve can only be opened when the fluid delivery conduit is received and clamped in the opening in the fluid reception conduit.

Abstract: A low phase noise frequency multiplier is disclosed for multiplying a sine wave obtained from a low phase noise crystal oscillator to higher frequencies than can be directly obtained from a crystal oscillator. The multiplication occurs without the ordinary increase in phase noise. The multiplier, when tripling the frequency contains a low phase noise frequency doubler (21). The double and triple frequency terms in the tripler are synthesized from two orthogonally related derivatives of the same wave, which are then multiplied in a double balanced mixer (22). The process reinforces the desired harmonics while not reinforcing the short term random phase noise, and produces a substantial improvement in the single sideband phase noise ratio over conventional frequency multipliers.
