Title: Magnetic anti-theft and identification tag
Inventor: SCHROTT ALEJANDRO GABRIEL
IPC: G01V15/00
Filed: 1997-05-19
Abstract: A magnetic anti-theft and identification tag 206 for concealing in an article such as a SIMM 115, microprocessor, memory or logic chip or board has an amorphous wire 101 and an array of magnetic elements 201 in the form of strips of foil, wire or magnetic ink. The amorphous wire 101 acts as an anti-theft element which is detectable when passing through an interrogation field and the array of elements provides identifying information in the form of a code which can be read by a sensing head 205. The array may be binary coded in various ways, for example by leaving out or magnetizing selected elements or magnetizing elements in opposite directions 203, 204. The elements may be soft elements driven by an applied local a.c. field from the sensor head. Two parallel rows of elements may be used. Various sensor heads are described, consisting of one or more small magnetic circuits coupled to one or more pickup loops. Some heads utilise the Matteucci effect. The wire 101 may form an integral part of the array for coding information.

[Also in Division B2] Glass-paper substitutes are made by coating with an adherent coating containing powdered glass or other abrasives oriented and unoriented olefin polymer or copolymer films which have been subjected to a surface oxidizing treatment and anchor-coated with a solution or dispersion of an amine-formaldehyde thermosetting resin (i.e. a resin obtained by condensing formaldehyde and an amino compound such as used, thiourea, melamine or guanamine and resins of this type modified, e.g. by etherification with a lower alkanol in the presence of a strong acid catalyst) and a quantity up to 75% by weight of the anchor-coating dry weight of an alkyd resin derived from phthalic acid, the amineformaldehyde resin being substantially insoluble in water and compatible with the alkyd resin, drying off the anchor-coating and thereafter applying an aqueous dispersion of a heatsealable coating polymer which is dried off under conditions such that the amine-formaldehyde thermosetting resin layer becomes adhesively bonded to the base and coating films. The thermosetting resin layer may comprise an acid curing catalyst and a plasticizer e.g. a polymethylene glycol aliphatic dicarboxylic acid polyester which may be modified with a fatty acid. The heat-sealable coating may comprise cationic surface-active agents having antistatic properties (examples are given), antioxidants, dyes, pigments, lubricants, antiblocking agents, U.V. light stabilizers and slip agents of either the waxy or comminuted solid type.

Title: Jet texturing nozzle and baffle device
Inventor: BERTSCH GOTTHILF
IPC: D02J1/08
Filed: 1998-05-26
Abstract: The baffle device 26 has a first plane face and a second rounded face. The air stream 33 and the yarn 32 are deflected roughly at right angles by the first plane face upon exiting the texturing duct TK. After the transition from the first plane face into the second rounded face, the yam path and the air stream are separated. An extended path is formed round the baffle device for the yarn. The direction of the issuing air and of the yarn take off are therefore opposite. The intensity of texturing is very high. Compact yarns with regular  loop formation are achieved even with very high yarn titres.

Title: Rolling bearing
Inventor: OKITA SHIGERU
IPC: C23C8/32
Filed: 1995-09-29
Abstract: A rolling bearing has the following components: an inner race, an outer race and rolling elements. One of the components is formed of an alloy steel containing 0.1-1.0 wt% of C, 0.1-1.5 wt% of Si, 0.1-1.5 wt% of Mn and 0.1-3.0 wt% of Cr. The alloy steel is carbonitrided and then ground to form a surface layer having a carbon and a nitrogen concentration of 0.6-1.5 wt% and 0.3-0.9 wt%, respectively. The surface layer has an appropriate amount of retained austenite γ R  and is sufficiently hard to ensure long life. By optimizing the choice of constituent materials, processing methods and heat treatments for each of the rolling elements and the inner and outer races, rolling bearings that have high performance can be produced at low cost.

Title: Dielectric composites
Inventor: SHEPHERD TERENCE JOHN
IPC: B29C67/00
Filed: 1997-10-06
Abstract: A novel method of fabrication of periodic dielectric composites involving a flexible computer design stage, rapid growth of a second dielectric component. Laser stereolithography is used to form the polymer material layer by layer by photopolymerisation of a liquid. Certain materials constructed in this fashion exhibit a complete loss-free barrier to microwave propagation through the material for a desired band of frequencies and are commonly known as photonic band gap crystals. Such materials could provide a novel medium for all-angle wide- and narrow-band blocking filters, narrow-band transmission filters, reflective and loss-free substrates for planar antennas, and novel loss-free media for oscillator cavities and waveguides. In addition a novel crystal structure, particularly suited to the fabrication method mentioned above and consisting of concatenated polyhedrons, is revealed.
