Abstract: ABSTRACT OF THE DISCLOSURE         A novel immunoassay technique is provided employing sacs having a lysable membrane and at least one determinant or epitopic site recognizable by an antibody.  Enclosed in the sacs are water soluble stable free radical compounds, which are capable of escape from the sac upon lysis.  The immunoassay can be employed for determination of an epitope containing compound, anti-bodies or complement.         The basic modes are employed.  The first mode depends upon the difference in the EPR spectrum of the stable free radical when enclosed in the sac, at relatively high localized concentra-tion, and when free in solution, at relatively low concentration. The amount of the free radical compound free in solution is dependent upon available antibody bound to the sacs and available complement.         The second mode can be used for the determination of an epitope containing compound or antibody.  In this mode, the antibody agglutinates the sacs, the agglutinated sacs are separated from the non-agglutinated sacs and either or both of the dif-ferentiated sacs lysed and the amount of free radical determined.         The immunoassay is extremely sensitive and has a high multiplication factor, because a single event results in the free-ing of a large number of free radical molecules.

Abstract: ABSTRACT OF THE DISCLOSURE         An ignition circuit of the capacitor discharge type is disclosed for internal combustion engines. The circuit com-prises a transistor inverter which supplies a voltage doubler to charge a storage capacitor.  The storage capacitor is connected to an ignition coil through a thyristor.  Control means for the thyristor includes engine breaker points or equiv-alent for alternately preventing and enabling turn-on of the thyristor.  A voltage divider provides gate triggering current to the thyristor on each cycle of the voltage supply.  This produces either single or multiple ignition pulses for each breaker point cycle, depending upon the engine speed. The voltage divider includes a leakage resistor to limit the initial pulse and to allow current flow through the breaker points and also includes an isolation resistor to render the triggering point of the thyristor immune to changes in the breaker point circuit.

Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a rotatable one-piece plastic fixing member intended for use with a support panel which includes two flat surfaces facing in opposite directions and a non-circular aperture through the panel.  The fixing member comprises two supporting portions coupled to each other by a rigid rod and spaced apart by a distance equal to the thick-ness of the support panel with the rigid rod having a lateral extent less than the minimum diametrical distance of the aperture.  The first supporting portion which forms one end portion of the rod engages against the first surface of the support panel and has, perpendicular to the longitudinal axis of the fixing member, a noncircular contour complementary to that of the noncircular aperture of the panel.  The non-circular contour includes at least two axes of symmetry, and the second supporting portion which forms the other end portion of the rod engages the second surface of the support panel.  The fixing member further has at least two resiliently mounted locking bosses extending between the two supporting portions and fixedly attached to at least one of the two supporting portions, the bosses being spaced apart a distance, and having external contours to fit complementarily into two diametrically opposite parts of the internal surface of the aper-ture.  The bosses have a plane of symmetry passing through the axis of the fixing member, and that plane of symmetry forms with the plane of an axis of symmetry of the first supporting portion an angle equal to a fraction of a turn of predetermined value.

Abstract: Abstract of the Disclosure The preservation of metabolically active matter such as fruit, vegetables, meat, fowl, shrimp, fish, other food, cut flowers, cuttings, foliage plants and the like is disclosed, characterized by storage at controlled and correlated conditions of hypobaric pressure, temperature, humidity, air circulation and air exchange.  Preferably, a non-deleterious gas such as air is humidified by contacting it with heated water from a supply, and then the humid air is passed through, and when advisable, recirculated and/or rehumidified within a storage chamber containing the metabolically active matter.  The relative humidity is maintained within the range of about 80 to 100 percent and the pressure is maintained continuously or intermittently at a selected value at least slightly higher than the vapor pressure of the water in the stored commodity.  Storage of metabolically active matter in this manner delays or prevents spoilage resulting from such causes as aging, senescence, decay, putrefaction, desiccation, ripening, and the like, and preserves it for a long period of time as, for example, between harvest or slaughter and an advantageously delayed date of sale or consumption.

Abstract: ABSTRACT OF THE DISCLOSURE        A sliding clasp fastener has a pair of interengageable open-end fittings whereby the fastener stringers may be completely separated one from the other.  Each fitting comprises hooking means at each side of a plane parallel to the tapes and transversely opposed surfaces to overlap surfaces of the other fitting.  More specifically, each stringer has a series of coupling elements secured to an edge of a carrier tape, the two series of coupling elements being interengaged and disengaged by movement of a slider longitudinally of the stringers, and a pair of interengageable releasably connectable end fittings secured one to each of the carrier tapes adjacent an end of the series of coupling elements.  Each end fitting comprises two hooking means positioned one at each side of a plane which is substantially parallel with a plane of the carrier tapes, both hooking means of the one fitting being directed away from its associated series of coupling elements and forming two recesses to receive the hooking means of the other fitting. Both hooking means of the other fitting are directed toward its associated series of coupling elements and form two recesses to receive the hooking means of said one fitting. The hooking means of the pair of end fittings are mutually engageable in one longitudinal direction.  Each end fitting further comprises transversely opposed surfaces formed by side surfaces of the hook-ing means, the two hooking means of each end fitting being offset one from the other so that sides of the two hooking means provide said transversely opposed surfaces.  The offset in the two end fittings are in opposite lateral directions when the end fittings are interengaged so that sides of the hook-ing means of one end fitting laterally overlap sides of the hooking means of the other end fitting.  The resulting arrangement is such that, when the two series of coupling elements and the pair of end fittings are interengaged, the hooking means prevent separation of the end fittings laterally of the carrier tapes, the transversely opposed surfaces of the end fittings prevent separa-tion thereof transversely to the plane of the carrier tapes, and the inter-engagement of the coupling elements prevents longitudinally separation in the opposite longitudinal direction.
