Abstract: Abstract of the Disclosure Compositions hardonable by exposure to heat or electromagnetic radiation are provided by dissolving together to form a blend from about 0% to about 50% by weight of an uncrosslinked polymer, from about 2% to about 30° of a polymerizable monomer, from about 10% to about 70% of a crosslinked polymer in the form of discrete particles having average diameters of from 0.001 micron to about 500 microns and being swollen in said solution and from about 20% to about 70% of a crosslinking agent for said monomer.  Such compositions exhibit superior chemical and physical characteristics when hardened and are suitable in a wide variety of applications as construction media.  Such compositions are especially suitable in the production of prosthetic dental appliances, such as, for example, prosthetic teeth.  It is believed that the hardening of such compositions as, for example, during the preparation of dental appliances forms a polymer system known as an interpenetrating polymer network.

Abstract: ABSTRACT OF THE DISCLOSURE A solid state load protection system whereby the current supplied to a load is monitored enabling ground fault sensing to be used.  A current sensor is utilized so as to produce an output current which is proportional to the current in the electrical circuit.  Attached to the current sensing function is a resistive load which con-verts the current produced by the current sensing function to a voltage which is also proportional to the current utilized by the motor.  Attached between two  resistors which comprise the resistive load is a ground fault resis-tor which has its remaining end connected to the neutral leg of the current transformers of the current sensing function.  The ground fault sensor monitors the voltage across the resistors in the resistive load and the current in the neutral leg of the current sensors.  A ground fault condition is indicated when a current in the neutral leg of the  current  sensor  is  detected  and  thereby  causes voltages across each of the resistive load resistors to be unequal to each other.  If this condition is in excess of a predetermined level, for a predetermined period of time a trip signal to the output function is initiated, in turn causing a light-emitting diode to conduct and indicating a ground fault condition.  The output function upon receiv-ing a trip signal causes a second light-emitting diode to conduct and also de-energizes a contractor through which a current source is connected to a load.

Abstract: ABSTRACT OF THE DISCLOSURE Signal conditioning apparatus for reducing the noise frequencies of a speed representing signal being fed into a compensator for compensating the output of a synchronous generator for the effect of torsional oscillation between masses in the main AC generator sys-tem.  The signal conditioning apparatus includes two speed sensing transducers mounted 180° apart on opposite sides of a tooth gear wheel and summing the two FM output sig-nals from the transducers to eliminate odd harmonics of the synchronous frequency in FM noise due to eccentricity. The preferred embodiment of the invention reduces the remaining noise from the sensed speed signal by the use of a three-pole Butterworth low-pass filter in combination with a notch filter tuned to the turbine-generator syn-chronous frequency to thereby reduce the unwanted noise to a large degree while providing a minimal phase shift to the sensed speed signal.  Another embodiment of the in-vention may be used to determine the machining accuracy of the toothed gear wheel.

Les points d'action des leviers longs (3a, 3b) sur la pièce de transmission de force (29) étant à distance négligeable du plan de symétrie de la lame-ressort (18, 21), la force transmise à cette lame est pratiquement verticale et égale à la somme des forces exercées sur les leviers (3a, 3b, 4a, 4b) par le plateau porteur de charge, même si la répartition de la charge sur ce plateau est dissymétrique et si la base et le plateau se déforment légèrement sous l'effet de la charge. La précision de l'appareil est ainsi pratiquement indépendante de ces déformations. Fig. 1 et 4
