Abstract: Abstract of the Disclosure A web-like fibrous material consisting of fibres standing on end is produced from a starting material consisting of a web-like fibrous mater-ial, in which the fibres are oriented substantially transversely or longitu-dinally of the web.  The starting material is cut into strips which in well-known manner are arranged side by side with the fibres standing on end.  It is the object of the invention to eliminate the spaces or interfaces between these strips in a more efficient manner than has hitherto been possible.  To this end, the side-by-side pattern of strips is deposited on a perforated moving intermediary supporting surface, on which they are retained by a flow of air directed towards said surface and are at the time subjected by said flow of air to a spreading action transversely of the strips, whereafter the fibres are deposited at a second depositing position on a moving product receiving surface while at the same time interrupting the flow of air acting on the fibres being deposited.

Each tray's lips also cooperate with lateral stops on the upper shelf rails to prevent lateral spreading of the side walls where the basket is loaded.  Each side wall includes a stacking rib along the top edge thereof, and includes a stacking rail along the bottom edge thereof.  A first basket's stacking ribs are adapted to interfit with a second basket's stacking rails so that successive baskets may be stacked and retained one on top the other by the interfit of the stacking ribs and the stacking rails.

Abstract: ABSTRACT OF THE DISCLOSURE         A rotor assembly for a dynamoelectric generator having a spider  sub-assembly that is rotatable around a non-vertical axis;  characterized by having a plurality of articulated key assemblies positioned in aligned keyways formed, respectively, in the circumferential surface of the spider sub-assembly and in the inn er circumferential sur-face of an annular laminated rotor rim.  A base member in each of the key assemblies if formed to exceed by a predetermined length the normal, i.e., unheated, spacing between the rotor rim and the spider.  The rotor rim is heated to expand it radially so the base members of the key assemblies can be inserted in the aligned axial keyways in the rim and spider, then the rim is cooled to heat-shrink it against the base members of the key assemblies.  Pairs of tapered wedge keys are installed on opposite sides of the neck portions of each T-shaped base member of the res-pective key assemblies thereby to secure the laminations of the rim in aligned position and to lock the rim against tangential movement relative to the spider.

Abstract: PRESSURE TO ELECTRIC TRANSDUCER                     ABSTRACT OF THE DISCLOSURE       A pressure to electric transducer is described employing an electrical capacitance formed by two parallel metal plates separated by a variable air gap, one of the plates being fixedly mounted and the other being movable to change the spacing in direct proportion to fluid pressure acting on an input element or capsule to which the movable plate is connected. The capacitance forms one leg of a negative feed back divider network for controlling an operational amplifier  so that its gain is directly proportional to the spacing of the plates. The amplifier is driven by a constant alternating current source so that its output is directly proportional to the applied pressure.  The voltage output can be rectified and transformed in a conventional manner for transmission of a signal.

Abstract: ABSTRACT OF THE DISCLOSURE         Slag sand is produced by first mixing a stream of mol-ten slag with a quantity of between 0.5m3 and 0.7m3 of water per ton of slag to chill the slag while leaving it above the pyro-plasticity threshold.  Thereafter water at a rate of between 0.3 m3 and 0.4m3 is added to the slag to stiffen the stream and this stiffened stream is fed to a drum rotating at a rate between 600 rpm and 1000 rpm to break it up into fine granules which are collected on a foraminous belt.  The granulated slag produced has an extremely low moisture content so that it is ideally suited for use in slag cements.

Abstract: ABSTRACT OF THE DISCLOSURE         Pressurized boric acid is injected into the primary coolant of a water cooled nuclear reactor system to ensure sufficient shutdown reactivity in the event of an accident.  The method comprises heating a molten boric acid and water solution in a storage vessel, thereby creating sufficient pressure from the steam cushion which is generated to inject the solution into the reactor coolant.  When compared to known techniques for borating the primary coolant, this method has the advantage that a smaller storage vessel can be used for the solution and less power is consumed during injection.

Abstract: ABSTRACT OF THE DISCLOSURE An electric shock protective device for animals to protect, for example, a bandage affixed to one of the animal's legs. The device is positioned on or around the bandage, and if the animal attempts to bite or chew on the band-age, or the sore or wound on its leg, its mouth and tongue will come into contact with the protective device causing it to produce a mild electric shock. The device includes a flexible mounting band dimensioned to surround the leg of an animal for which it is intended, a plurality of electrical conductors such as thin copper bus bars mounted thereon in substantially parallel relationship, an elec-trical power source such as one or more electrically connected batteries having a negative and a positive terminal, a first one of said electrical conductors connected to said negative terminal and a second one of said electrical conductors connected to said positive terminal. The electrical conductors face outwardly when the protective device is wrapped around the bandaged leg, whereby the animal's tongue or mouth contacts both the said first and second conductors which completes an electrical circuit and produces an electrical shock to the portion of the tongue or mouth in contact with the conductors. More than two conductors may be mounted in parallel spaced apart relationship on the flexible mounting band, in which case they are connected so each adjacent one is of opposite polarity.
