Abstract: Un ensemble d'engrenages fournit un certain nombre de rapports de régime par l'intermédiaire d'embrayages fonctionnant par pression hydraulique (C1, C2) au moyen d'organes de commande (26, 29 : 33, 36). Ces organes de commande sont commandés par des soupapes d'inversion de débit à deux positions (50, 51), une soupape pour chaque organe de commande fonctionnant par pression hydraulique. Ces soupapes sont reliées hydrauliquement en série avec un organe de commande au moins (33, 36) connecté en aval de la dernière soupape (51) de la liaison en série et un organe de commande au moins (26, 29) connecté entre chacune des soupapes de la série. Un moyen de commande de soupape (50a-54) sert à commander la séquence de fonctionnement des soupapes pour qu'en modifiant le régime d'une soupape à la fois, on puisse modifier le rapport de régime de l'ensemble d'engrenages d'après le rapport le plus rapproché de l'ensemble, d'une façon progressive sur toute la plage de rapports dudit ensemble. Dans l'ensemble à quatre rapports que l'invention décrit, un premier embrayage fonctionnant par pression hydraulique (C1) est accouplé à un premier embrayage venant en prise par ressort (C4) et le deuxième embrayage fonctionnant par pression hydraulique (C2) est accouplé à un deuxième embrayage venant en prise par ressort (C3), pour que, quand l'embrayage à pression hydraulique de chaque couple est en prise, l'embrayage venant en prise par ressort du couple respectif est désembrayé automatiquement et vice versa, en créant des conditions d'embrayage à quatre rapports.

IPC: H03F1/52
Filed: 1992-10-19
Abstract: An amplifier comprising a power stage (1) the output (V O ) of which is compared with a reference level (V R1 , V R2 ) by a comparator (7). If the output (V O ) exceeds the reference level, a reduction is made in the gain of a variable-gain cell (5) upstream from the power stage. The reference level varies with temperature, and, more specifically, presents a high constant value (e.g. greater than the supply voltage) when temperature is below a predetermined threshold (e.g. 130°C), and falls alongside an increase in temperature, when this exceeds the predetermined threshold. Thus, the input signal (V IN ) is only attenuated in the event the output signal exceeds given values inversely proportional to temperature, and with no reduction in peak output at high temperature.

Abstract: Audio to be recorded in a photographic film camera in association with individual exposed frames is first digitized and stored in a temporary storage memory (26) in the camera allowing playback through a speaker (20) mounted in the camera to permit playback review and editing, as needed. When the film is advanced in the camera to the next exposure frame, the digital audio signal is recorded on a magnetic layer (13) formed on the film. At the photofinisher, the digital audio signal is read and converted to suitable encodement format, such as bar code or binary coded blister marks which are impressed on the photoprint for subsequent playback.

Abstract: A phase difference autofocus method that only requires one FFT (17) for estimating a phase error in the entire synthetic array radar data. The phase difference autofocus method of the present invention automatically and efficiently estimates phase errors from radar signals, allowing a well focused SAR image to be produced. The present method comprises the following steps. First, each range bin is divided into two subarrays. Next, the two subarrays are complex-conjugate multiplied together (13) to produce a cross spectrum of the two submaps produced by the subarrays. Then, the phases of each cross spectrum are aligned with an accumulated sum of the cross spectrums from previous processed rage bins (24). The phase aligned cross spectrum is then added to the accumulated cross spectrum sum (27). All range bins are processed to get a final cross spectrum sum. Next, a single FFT (17) is performed on the final cross spectrum sum to produce the cross correlation function. Then, the cross correlation function is magnitude-detected (18). Since the location of the peak of the cross correlation function is proportional to the phase error, a phase error estimate is obtained. Finally, the phase error correction signal is produced for the entire synthetic array radar data. Since only one FFT is performed during autofocus processing, the method is relatively fast.

Abstract: In a preferred embodiment, taxol is treated with mesyl chloride to prepare a taxol derivative with a contracted A-ring, which has comparable activity to taxol in a tubulin depolymerization assay, and which shows cytotoxicity against KB cells in a cell culture assay. In an alternate preferred embodiment, taxol is treated with triethyloxonium tetrafluoroborate (Meerwein's reagent) to produce a taxol derivative with an opened oxetane ring. In another alternate preferred embodiment, reaction of taxol with acetyl chloride yields a taxol derivative in which the oxetane ring is opened and the A-ring is contracted. All of the aforementioned products show  in vivo  activity in KB cell culture assays. Further, the preferred compounds have different  in vivo  activities, which makes them ideal to form a range of standards for use in biological testing of other compounds.

Abstract: A method of introducing air into a room by passing supply air (A) into a distribution device (1) ending in the room (2) and by blowing the air from the distribution device through air supply openings (8, 9) into the room. In order to control the introduction of air even when the supply air is considerably warmer than the room air, the supply air is introduced into the distribution device selectively through two separate independent flow paths (4, 5) into the air supply openings, whereby the supply air is subjected to flow conditions required for heating at the air supply openings (8) of one flow path and correspondingly to flow conditions required for cooling at the air supply openings (9) of the other flow path. A distribution device carrying out the method comprises at least two separate alternative flow ducts (4, 5) for supply air, the flow ducts being provided with separate air supply openings (8, 9) which provide different flow conditions in the separate flow ducts.
