Abstract: TITLE EPOXY RESIN FORTIFIERS BASED ON AROMATIC AMIDES     INVENTORS                 Paul Douglas McLean Andrew Garton Robert Fredrick Scott Susan Elizabeth Gransden ABSTRACT OF THE DISCLOSURE The reaction product of (i) an aromatic amide having the amine group of the amide attached to an aromatic ring, and (ii) a mono- or di-epoxide, has been found to be a good fortifier of epoxy resins.  Epoxy resins have been found to attain increased strength and modulus (yet not brittle) by compounding:          (a)  a resin-forming polyepoxide, (b)  an amine curing agent for (a), and  (c)  the above fortifier; and heat curing the mixture. Strengths as high as 130-150 MPa and modulus values to as high as 5000 MPa have been achieved yet with a ductile mode of fracture.

Abstract: ABSTRACT OF THE DISCLOSURE           The enzyme, which is able to decompose a high molecular carbohydrate, abbreviated SPS (soluble poly-saccharide), is designated SPS-ase.  The SPS-ase is able to decompose SPS into decomposition products which attach themselves to protein in an aqueous medium to a lesser extent than the SPS prior to decomposition.  The method for selection of SPS-ase producing microorganisms is based on the fact that the main carbon source of a growth medium is SPS and on a qualitative SPS-agar plate test.  A method for production of an SPS-ase by means of a deposited strain of Asp. aculeatus is described.  TheSPS-ase also has utility in the fruit and vegetable industry and for the production of juice and wine.

Abstract: SCREEN PRINTING FRAME                        ABSTRACT        A screen printing frame is formed with hollow extruded metal frame members joined at their ends by extruded metal interfitting connectors which are retained within the ends of their associated frame members by frictional engagement supplemented by a bonding agent.  The force required to establish the frictional engagement is maintained in the preferred embodiment by elastic flexure of a bowed side wall on ech connector arm.  The structural members may have prefinished surfaces such as anodized surfaces and are joined together without welding as would mar such surfaces during the welding operation.  The amount of metal used for the extrusions has been minimized for cost reduction and to obtain a lightweight structure.         Grooves on the interfacing surfaces of the connector arms and the frame members cooperate to form an interstitial lattice which receives a bonding agent.  Miter joints at the corners of the structure are sealed by corner webs on the connectors in combination with a bonding agent.

Abstract: ABSTRACT OF THE DISCLOSURE A two axis linear motor for carrying the objective lens for optical focusing and optical tracking in an optical recording system has a stationary structure for providing a magnetic field and a moving armature structure. The stationary structure may have two permanent magnets and several pole pieces to properly shape the field with respect to the armature.  In one embodiment, a central elongated pole piece and two parallel adjacent elongated pole pieces are associated with two permanent magnets to form flux gaps with the central pole piece.  Flux returns to the magnets through a lower pole piece to which the central pole piece is attached.  The central and lower pole pieces have an aperture through which the laser beam may pass on its way to and from the objective lens.  The objective lens is carried by the armature body and positioned over the aperture in the central structure.  The armature body has focus coil windings in one orientation and tracking coil windings in an orthogonal orientation.  The tracking coil windings cause the armature to move back and forth in the direction of the elongated central magnet structure over which the armature fits. The tracking direction of the armature is radial with respect to the recording tracks on an optical recording disk.  The focus coil windings cause the armature to move up and down maintaining a constant distance between the objective lens and the optical media to keep the laser beam passing through the objective lens in focus.  Focusing motion and tracking motion may occur simultaneously or in any desired combination.  The armature structure is supported by a suspension flexure structure which eliminates rolling and yawing as well as translation in directions other than the focus or tracking directions of the armature structure. The moment of mass of the armature is centered in the suspension to reduce pitching of the armature about the axis perpendicular to the tracking axis of the armature structure.

Abstract: ABSTRACT           This  invention  relates  to  fasteners  for attaching trade or price tags to an article.   Prior art fasteners have limited length and therefore cannot be used on bulky,  thick articles.    This  invention provides  a fastener  assembly  comprising  a  plurality  of  fasteners joined by a string and which may be separated from the assembly.  Each fastener comprises a female member having an opening, a male member engageable in the opening, and a string member comprising a portion of the string joining the  fasteners.    The  string member passes through the female  and male members which are fused to it.   The individual fasteners are obtained by cutting the string between adjacent male and female members of the adjacent fasteners.   The string between each pair of male and female members may be adjusted in length to provide a fastener of any suitable length.
