Abstract: Un circuit redresseur (80) produit un signal de sortie redresse biphase presque parfait en reponse a la reception d'un signal d'entree applique differentiellement. Le circuit redresseur comprend une paire de redresseurs (88, 86, 90, 92 et 102, 104, 106, respectivement) qui ont des caracteristiques de transfert non lineaires sensiblement identiques a celle du premier des redresseurs recevant le signal d'entree applique differentiellement a la premiere et a la seconde entrees (82, 84). Un reflecteur de courant (96) ayant une entree couplee a un premier noeud (94) sur une sortie du premier redresseur envoie un signal de sortie qui est sensiblement identique au signal de sortie apparaissant a la sortie du premier redresseur. Le second redresseur possede une sortie connectee en un second noeud (98) sur la sortie du reflecteur de courant. Un circuit de reaction (100, 108) est couple entre le second noeud et une entree du second redresseur pour faire en sorte que le signal de sortie apparaissant a la sortie du second redresseur soit une version redressee biphasee du signal d'entree applique differentiellement. Le circuit redresseur se prete a une utilisation dans des systemes detecteurs video.

Abstract: For regeneration, the activated carbon filter loaded with impurities having a boiling point of at least 120 DEG C is treated with steam. The activated carbon is in a vessel, into which steam is introduced under pressure, whereby the vessel is pressurised to 1.5 to 10 bar and the activated carbon bed is thus heated to a temperature of about 110 to 180 DEG C. For washing out the desorbed substances, the pressure in the filter vessel is lowered again. The pressurising and letting-down of the filter vessel can be repeated several times.

Abstract: In order to remove a thin-walled wax model adhering to the walls of a first core piece and a second core piece, after solidifying, from a multi-part device for making thin-walled wax models, without damaging the wax model, after the external pressure is released, a mold-opening moment is generated simultaneously and abruptly in axially opposite directions by spring-loaded push-off bolts or directly by leaf springs in the upper parting faces and lower parting faces of the device. As a result, both the lower closing plate and the upper closing plate are separated from the annular casing and the wax model is separated from the core pieces, by a maximum of 3 mm, axially in opposite directions because the adhesion of the wax model to the walls of the core arrangements is overcome simultaneously and abruptly. Subsequently the two core arrangements and the casing are transported away from one another in an axial direction relative to one another, so that the wax model is freed.

Abstract: @ When driving an AC motor (6) with a PWM inverter (1 the width of a speed command signal (i u *) is modulated by a carrier (e) to produce width modulated pulses (S, S) for controlling main switching elements (3a, 3b). The width modulated pulses are liable to be attended with impulses (pn) which cause magnetic vibrations in the AC motor (6), resulting in noises. The generation of these impulses can be suppressed by changing the amplification factor of an amplifier (20) for the speed command signal or the amplitude of the carrier on the basis of the rate of change of the speed command signal. Noises which would attendant on low speed running of the AC motor (6) can be reduced by changing the amplification factor of the amplifier (20) and the amplitude of the carrier on the basis of detected frequency of the speed command signal or revolution of the AC motor (6) during low speed running.

Abstract: Alternate modes of digital subtraction angiography are described. In each, a sequence of alternate low and high energy x-ray exposures are made extending over an interval including periods before, during and after an x-ray contrast medium has entered and departed from the blood vessel of interest. In one mode the first low energy exposure or mask image is subtracted from the respective subsequent low energy images and the sequence of difference images are stored on disk. The high energy images subsequent to the first one or mask image are subtracted from the high energy mask and stored. The plot of the projected intensity of the contrast medium as a function of time is determined and the values of the bolus plot at any time are the matched filter coefficients by which the sequences of low energy and high energy difference images are multiplied in the matched filtering process. The matched filtered low and high energy sequence of difference images are summed in separate channels and the results are multiplied by weighting factors that result in bone being cancelled when the summed images are subtracted to produce the hybrid difference image. In the alternative mode, the signals representative of the alternate low and high energy exposures are subtracted during acquisition and the sequence of energy subtracted difference images are stored on disk. Before subtraction they are multiplied by respective weighting coefficients for cancelling bone when they are subtracted. The sequence of energy-subtracted images are then accessed from disk and subjected to matched filtering and summed to produce the hybrid difference image. In both modes, negative matched filter coefficient values are used which produce negative areas belowthe abscissa of the plot equal to the positive area of the bolus plot above the abscissa which, in effect, produces a dc component in the image signal that is equal to zero so everything that is constant in the sequence of images cancels out by subtraction.

Abstract: A single cycle continuous process is provided for preparing a novel highly oil absorbent peat product useful to control oil spills for oil spill clean up. The process involves preparing a mixture by mixing peat with an alkaline earth metal basic product, e.g., a magnesium/calcium hydroxide lime substitute material, e.g., at a ratio of peat/basic material of about 100/15. That mixture is heated, either directly in an oven or a microwave oven or indirectly by a heat exchanger in a rotating drum for a predetermined period of time, e.g., at a maximum temperature of about 160°C, for a maximum time of about 15 minutes, until the peat has the desired moisture content, e.g., about 5-10% by weight water. This novel product can absorb some 20 times its own weight of oil which makes it very advantageous for cleaning up oil spills either on land or on water. Also, the oil contained in the absorbent which has been used to clean the oil spills may be easily removed from the absorbent so that the absorbent can be reused.
