Abstract: FIRE BARRIER RESERVOIR                    ABSTRACT OF THE DISCLOSURE        A roofing structure including a plurality of abutting fireproof sections and a reservoir board having apertures therein, the reservoir board mounted on and secured to the sections of the fireproof member,  Insulation mounted on said reservoir board and covering said apertures therein.  In the event of a fire in the building covered by the roof, the insulation will become molten and under normal circumstances would flow on to the fireproof member and leak therefrom at the seems between abutting sections of the fireproof member and flow therethrough downwardly of the roof.  This molten insulation would serve to intensify the fire within the building.  Indicia is provided on the reservoir board to aid in the proper installation thereof so that the apertures therein will not be positioned above the seams in the fireproof member.  In a modification of the invention the reservoir board is eliminated and the fireproof member is provided with a plurality of cups formed therein to receive and to hold the molten insulation. A further modification involves a roofing structure in which the fire reservoir board upon which the insulation is mounted is composed of wood fiberboard and is provided with the apertures therein for holding the molten insulation and keeping it from flowing on to the lower roofing structure elements.  In this form of the invention the fireproof member is eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE      A button for being attached to a garment fabric has a button body composed of a double-walled tubular stem with an annular flange extending radially outwardly therefrom, a cap mounted on the button body and the cap, and a tack member having a central shank for penetrating the garment fabric into the tubular stem to join the tack member to the button body with the garment fabric interposed therebetween.          The annular flange includes a first marginal wall flaring radially outwardly and having a plurality of radially outward projections.  The cap also has a second  marginal wall fitted over the first marginal wall and including a plurality of protuberances deformed radially outwardly by the projections, respectively.  The projections and the protuberances   are held in interlocking engagement.  The shank of the tack member has a tapered end portion which, upon being forced into the button body, is elastically deformable against the back plate laterally into a retainer hood held in locking engagement with the tubular stem. The invention prevents the button body and the cap from rotating relative to each other.  Also, the button body flange is stiffened to increase the strength of the overall assembly.

Abstract: Abstract Breathing apparatus comprising a mask for defining a breathing chamber in communication with the nose of the user, a gas supply container having a movable valve control element, and an operator manipulated by the mouth of the user for moving the control to open the valve to introduce gas to the breathing chamber. As a result, control of the gas supply is provided by the mouth of the user and inhaling from and exhaling to the chamber is through the nose of the user.  The mask is shaped to contact the user's face around the nose and to define the breath-ing chamber in communication therewith, and the container of breathing gas is carried by the mask with the outlet valve com-municating with the chamber and operable by the movable control element.  The operator is carried by the body for operative association with the mouth of the user for moving the valve con-trol element between open and closed positions in response to manipulation by the mouth of the user, and an exhalation valve is in the mask in communication with the breathing chamber.  As a result, the supply of breathing gas from the container to the breathing chamber is controlled by the user manipulating the operator with his mouth and inhalation from and exhalation to the breathing chamber is performed by the user through his nose. If desired, there can be included a fluid-tight connector be-tween the gas supply container outlet and an inlet to the breath-ing chamber, a manually operated member for opening and closing the valve, and a pressure gauge in the container for monitoring the pressure of the contents thereof.

Abstract: RD-14,894 POWER SEMICONDUCTOR DEVICE WITH MAIN CURRENT       SECTION AND EMULATION CURRENT SECTION    Abstract of the Disclosure A power semiconductor device incorporates in its active, or current-carrying, region a main current section and an emulation current section.  The active region is surrounded by a common device termination region.  This is accomplished through provision of respective separate cathodes for the main and emulation current regions, while the device anode is common to both the main and emulation current sections.  The current level in the emulation current section provides an accurate represen-tation of the current level in the main current section since the main and emulation current sections are closely coupled both thermally and electrically and, further, are formed in the same fabrication process.  The current level in the main current section can be economically determined with low power circuitry by way of sensing the current level in the emulation current section.

Abstract: LENS EDGING MACHINE AND METHOD            Abstract of the Disclosure A machine for grinding the peripheries of ophthalmic lenses to predetermined outlines is characterized by a head having a rotatable workholder for moving an edge of a lens against a rough grinding or finishing wheel and a pattern holder positioned vertically above the workholder for controlling movement of the lens toward and away from the grinding wheel.          The head is mounted for horizontal, vertical and pivotal movement, is allowed to freely pivot during finishing or bevel edging of a lens but not during rough grinding, and is automatically locked against pivotal movement upon completion of bevel edging so that the lens may, if required, be returned to the same position against the finishing wheel.  Circuitry controls movement of the head in accordance with the base curve of a lens to precisely position the lens with respect to the finishing wheel, and maintains the machine in each of its rough grinding and finishing stages for a period of time which is sufficient to complete the grinding operation and independent of the number of rotations of the workholder.

Abstract: ABSTRACT Process for the production of technical grade biuret, readily in a form suitable for use as animal feed, by the controlled pyrolysis of urea in two stages, the first stage involving the partial pyrolysis of urea at a temperature above the melting point of urea to produce a first stage intermediate reaction product containing from about 20% to about 60% urea, and not more than about 25% cyanuric acid by weight, such reaction product being then cooled and comminuted, the comminuted product then being subjected, in solid form and in the absence of a liquid carrier, to a temperature at or slightly below the softening point of a solid particulate (suitable at a temperature of from about 100°C. to about 140°C.) with forced air circulation through the comminuted product for a sufficient time to lower its urea content by partial sublimation of the urea and partial further reaction thereof to biuret with only minimal further conversion of urea to cyanuric acid. Crystallization and cooling of the molten intermediate product resulting from the first stage of pyrolyzation is advantageously accelerated by addition thereof of a powered seed material, preferably including powered feed grade biuret from a previous run, which additive serves to also increase the melting point of the product and thus increase the temperature at which it may be heated during sold state pyrolyzation.
