Abstract: ABSTRACT OF THE DISCLOSURE             This invention relates to the stimulation of mushroom growth by the supplementation of nutrients utilized by the mushroom. If the nutrients are admixed into the compost before spawning of the mycelium, the extent of stimulation is necessarily limited by the heat evolution, by the stimulation of com-peting microorganisms, and by the fact that the stimulation of mushroom growth seems to be restricted primarily to the first several flushes.  If the nutrients are added at the time of casing, the heat evolution caused by the increased metabolic rates of the mushroom mycelium, the practical difficulties in mixing, the danger of the spread of pathogens or the stimulation of competing molds renders supplementation at this stage impractical for commercial utilization.  This invention provides a means of providing nutrients to enhance the growth of mushroom mycelium whereby the nutrients are admixed into the compost at the period of spawning, without the above mentioned problems.          According to this invention, denatured protein is used as a nutrient supplement for the stimulation of the growth of mushroom mycelium.  The denatured protein is admixed into the compost growing medium before or shortly after spawn-ing.  A synergistic effect is attained by admixing a vegetable oil, or fish oil with the denatured protein.

Abstract: METHOD AND APPARATUS FOR GUYING A LOAD BEARING MEMBER            Abstract of the Disclosure A system for guying a tower on which a force is exerted in a direction transverse to the elongate dimension thereof includes a plurality of guys interconnected between the tower and respective anchors. The guys are placed under a tension load to oppose the force exerted on the tower. An extensible device, such as a hydraulic piston and cylinder assembly, is serially interconnected with the guys at a location between the tower and the anchor. Before a force is exerted on the tower, the piston and cylinder assemblies are pre-pressurized with hydraulic fluid so as to retract the pistons and thus reduce the effective length of the guys. When the load on the guy bearing the greatest tension load reaches a predetermined value, hydraulic fluid is relieved from its associated piston and cylinder assembly, allowing the assembly to extend and increase the effective length of that guy. As this occurs, the tower will translate in the direction of the load exerted thereon, transferring a portion of the tension load that would otherwise be borne by the guy bearing the greatest load to the remaining guys. The tension load at which the piston and cylinder assembly extends is predetermined so as to prevent the tension load per unit cross-sectional area of its associated guy from exceeding the ultimate strength of that guy.

Abstract: ABSTRACT OF THE DISCLOSURE           A sensitive direct immunoassay system is provided for the detection of an antigen associated with hepatitis in body fluids.  An antibody which reacts with a hepatitis antigen or antigens and which is uniformly bonded to an insoluble member com-prising a polymeric material having irregular surfaces, is incubated with a test sample.  During this first incubation, a portion of an antigen present in the test sample will combine with the antibody immobilized on the insoluble member.  The antibody bonded member, to which antigen is attached, is then washed and incubated with an enzyme tagged antibody reagent comprising immunochemically reactive hepatitis antibody conjugated with a functional enzyme such as alkaline phosphatase.      During the second incubation, the tagged antibody reacts with antigen fixed to the insoluble member in the first incubation.          Thus, a "sandwich" is formed of an insoluble member- antibody-antigen- enzyme tagged antibody.      After the second incubation, the member is washed again to remove unreacted enzyme-antibody conjugate reagent.  The member is then exposed to a substrate which is induced by the now immobilized enzyme to produce a detectable end product. The enzyme-antibody conjugate will be fixed in the second incubation only if antigen was present in the sample.  The amount of enzyme tagged antibody fixed is proportional to the amount of antigen or antigens present in the test sample up to the maximum capacity of the test. The concentration of the end product, and hence the amount of antigen or antigens, is determined by a spectro-photometer which measures the optical absorption of light by the end product.  This readout is then compared against a standard value for both antigen negative and antigen positive samples.           All reagents for the test may be conveniently fur-nished in the form of a kit which has an extended shelf life and greatly simplifies the procedure.

Abstract: ABSTRACT         The disclosure concerns a hydroelectric machine including a tube-type hydraulic machine having a bladed wheel which carries adjustable blades, rotates about a horizontal axis and is connected with a shaft which extends into a guide blade lattice hub, and an electrical machine which surrounds the bladed wheel and has a rotor secured to an annular rim in which the external ends of the adjustable wheel blades are pivotably mounted. The rotating set is provided with three radial bearing arrangements, one being associated with the rotating unit formed by the rotor and the rim, providing sole radial support for that unit, and consisting exclusively of hydrostatic devices which support without physical contact.          The other bearing arrangements are associated with the shaft at its free and bladed wheel ends, respectively.  The bearing arrangement at the free shaft end and one of the other bearing arrangements center the rotating set with respect to the axis of rotation and are the only bearings which perform this function.  The remaining radial bearings provide a constant supporting force when there are slow radial movements of the rotating set and a progressively increasing supporting force when there are sudden radial movements of that set.

Abstract: OPTICAL SCANNER                Abstract of the Disclosure This disclosure provides an optical scanner for transforming an optical image into electrical signals.         Through practice of this disclosure an optical image is projected onto a surface of a photosensitive semi-conductor body wherein there is established a charge distribution or perturbation or pattern which reflects the variations in optical intensity of the optical image.    Through the parametric interaction of simultaneously applied electric field and acoustic wave to each respective portion of the electrical charge pattern on the photosensi-tive semiconductor surface, there is obtained a backward acoustic wave which is directed toward the source of the initiating acoustic wave.  In particular, the acoustic wave in the acoustic medium may be either a surface acoustic wave (SAW) or a bulk acoustic wave.  Where the surface acoustic wave is utilized, the acoustic medium may be commensurately thin.  The acoustic medium must be piezoelectric for it is the interaction of the electric field of the acoustic wave with the applied electric field via the charge pattern which achieves the parametric interaction.  Through the "holographic" electric field echo effect, an optical scanner may be achieved for the practice of this disclosure by storage of a charge pattern related to the optical image.

Abstract: BALER LOADING METHOD AND APPARATUS                      ABSTRACT OF THE DISCLOSURE           If the next charge to be stuffed into the baling chamber has not yet reached the desired size and density by the time the stuffing fork and compacting plunger are ready to begin their next operating cycles, the plunger and the fork are temporarily deactivated until the charge reaches full size and density.  Thereupon, the fork stuffs the entire charge into the baling chamber in a single cycle of operation for compaction by the plunger.  The baler is loaded from the bottom of the baling chamber through an upwardly curved duct that serves both as an accumulating chamber and as a pre-compression area into which the charge is progressively packed by a rotating, retractable finger drum at the lower end of the duct.  The plunger closes the top of the duct during such accumulation and pre-compression, and in order to provide ample time for the plunger to retract from the duct when the stuffing cycle commences, the fork moves slowly at first but then quite rapidly once the plunger has retracted.  Actuation of the plunger and stuffing fork occurs automatically in response to obtaining the predetermined density of the accumu-lated charge as sensed by a pressure-sensitive device on the loading duct.
