Abstract: A power supply circuit including a controllable switch is described. During normal operation of the supply, its DC output voltage is maintained at a substantially constant, first value in spite of variations of the DC input voltage and of the load on the output voltage sbecause the duration of the conductivity time of the switch is controlled. A function generator supplies a signal, which is a given function of the output voltage, to a control input of a pulse duration modulator for determining the duration of the conductivity time. At an output voltage which is considerably lower than the first value the signal of a starting circuit is passed on by a selection circuit to the said control input for causing the conductivity time of the switch to increase, which signal corresponds to a shorter conductivity time than the signal of the function generator. At the instant when the output voltage reaches the first value, the selection circuit passes on the signal of the function generator.

Abstract: The dehydration process substantially consists in causing the fabric (1) in rope form to continuously advance between at least two pairs (2, 12) of pressing rolls, with it being simultaneously submitted to a false twisting. The false twist causes a wringing of the fabric with the consequent partial evacuation of the liquid the fabric is sodden with. In order to improve the dehydration, a centrifugation of the twisted fabric is provided for. 
     The apparatus substantially comprises a twisting organ (3) capable of giving a false twist to the running fabric. The twisting organ can be constituted by a revolving structure capable of causing the fabric to run along a path outside its advancement axis, with the fabric thereby simultaneously undergoing a twist and a centrifugation.

Abstract: A method of reducing image artifacts in tomographic projection imaging systems uses the projection data acquired with continuous gantry (16) motion and a variable table (14) velocity to transport the imaged object past the rotating gantry (16). The table (14) velocity is decreased when the projections are being acquired near the slice plane and increased when the projections being acquired are further from the slice plane. The table (14) position is coordinated with the acquisition of projections so that the middle projections of the tomographic projection set are acquired close to the slice plane and the beginning and end projections are acquired when the projections are taken furthest from the slice plane. Interpolation procedures are used to further reduce image artifacts resulting from the taking of projection data at points removed from the slice plane.

Abstract: The chemical composition of the present invention is capable of forming a water soluble but curable film on fibers treated with the aqueous chemical composition to produce wet chopped strands of the fibers. In one aspect the chemical composition has a water soluble film-forming polymer with an intrinsic viscosity less than around 150 centipoise present in an effective amount to form a water soluble film. In addition the composition has at least one cationic lubricant or lubricating surfactant, polymer matrix-compatible organo silane coupling agents, epichlorohydrin polyamide adduct, and water. The film forming polymer can be poly(vinylalcohol), poly(vinylpyrrolidone), or poly(hydroxyalkylcellulose) or mixtures thereof and the like. The organo silane coupling agent can be a lubricated alkoxylated gamma aminoalkyltrialkoxy silane, a polyamino organo silane, mercapto functional organo silane, vinyl functional organo silane, or a ureido functional organo silane or a mixture thereof. The amounts of the silane, lubricant and adduct are, respectively, around 1 to 20, around 0.5 to 15 and around 0.5 to around 15 all based on the weight percent of the nonaqueous solids of the chemical composition. Glass fibers treated with the chemical composition are particularly useful as wet chopped glass fiber strands for reinforcing thermoplastic polymers, where the fiber reinforced polymer in made by a foamed wet-laid process having the thermoplastic polymer present from particles in the pulping medium.
