Patent EP-0242949-A1 (EP)
Inventor: WILLIAMS DAVID J
IPC: C08L79/08
Filed: 1987-02-17
Abstract: Novel miscible compositions comprising from about 1 part by weight to about 99 parts by weight of an aromatic polyimide or polyetherimide and from about 99 parts by weight to about 1 part by weight of an aromatic polybenzimidazole. In a composition mostly comprised of an aromatic polybenzimidazole, it is preferred that the aromatic polyimide be thermoplastic and that it or the aromatic polyetherimide be present in the composition in an amount sufficient to make the aromatic polybenzimidazole more processable for molding purposes and also less susceptible to moisture. In a composition mostly comprised of a soluble, thermoplastic aromatic polyimide or aromatic polyetherimide, it is preferred that the aromatic polybenzimidazole be present in an amount sufficient to render the soluble thermoplastic aromatic polyimide or aromatic polyetherimide less sensitive to solvents, and to increase the glass transition temperature of the aromatic polyimide or polyetherimide. Phase-separated compositions may be formed from the miscible compositions by heating a composition above its binodal or spinodal phase boundary temperature or glass transition temperature to cause it to phase separate and then quickly quench-cooling it to freeze the phase-separated morphology. The novel compositions are useful under severe environmental conditions. The compositions have good impact resistance, enhanced solvent resistance and generally good price-performance characteristics.

Title: Servo system for a hard disk drive
Inventor: HOSHIMA SUSUMU SONY CORPORATIO
IPC: G11B21/10
Filed: 1987-06-08
Abstract: A hard disk system has servo head means (Hs) for generating track-crossing information in addition to R/W head means (Hrw) for performing data read/write operations. Servo signals of sector shape extracted from the R/W head means (Hrw) are such that their positions are different in the lengthwise direction of the tracks as between signals recorded on different disk surfaces. The R/W head (Hrw) is positioned in the neighbourhood of a target track using the track-crossing information. The centre of the R/W head means (Hrw) is then positioned at the centre of the target track using the servo signals extracted by the R/W head means (Hrw).

Title: Wrap-around packaging machine.
Inventor: CONFORTO PETER MICHAEL
IPC: B65B/
Filed: 1987-09-08
Abstract: A blank for forming a wrap-around carton is delivered to a moving support carriage which is moved to a station where the moving carriage receives a predetermined number of articles to be packaged. The carriage, with the articles resting on the bottom portion of the blank, is moved downstream while cams actuate tucker fingers which pivot up to fold the tuck flaps of the blank toward each other, causing the end and side panels to be elevated. Another cam actuates a pusher bar which pivots up to push the articles. The carton blank and the articles are thus positively moved through subsequent flap folding and gluing stations, avoiding the problems which can arise due to the use of separate means for moving the articles and the carton blank. A cam operated hinged plate is used to segregate the leading articles at the entry to the machine.

Inventor: PUTZ ALBAN
IPC: D01F11/12

Abstract: The metallised textile web of the present invention represents a homogeneous metal layer on a textile web, which is almost as flexible as the textile web itself, provided the latter comprises fabrics made of glass fibres, synthetic resin fibres, carbon fibres and the like; it is therefore suitable inter alia for a wallpaper-like metallic lining of a room on all sides. 
<??>Thus, it has become possible by means of this invention to create electrically impenetrable Faraday cages from an elastic, i.e. shockproof and non-deformable, material and hence to provide an effective counter to one of the great technical challenges of our time, namely electronic piracy. 
<??>The invention is based on the discovery that when a workpiece is sprayed with arc-melted bar metal spidery microscopic metal particles (5) are formed on the workpiece, while spraying with a metal powder melted in a gas flame will produce spherical or droplet-shaped particles (6). The "legs" of the spidery metal particles (5) interpenetrate and interlace to form an elastically flexible metal cover which is made electrically impenetrable by sealing with a spray of metal balls (6); cf. the accompanying illustration.

Abstract: The sealing rings, arranged in an installation space, have a sealing part (2) with a sealing lip (20) which is attached to a bowl- shaped supporting body (1). It has a jacket (11) which, like the sealing lip (20), consists of an elastic material. As a result of the jacket (11) and sealing part (2) consisting of the same materials, no deliberate matching to the respective requirements can be achieved. In order to ensure a firm seat of the sealing part (2) with reliable corrosion protection and static sealing, and in order to be able to match the sealing lip (20) to the respective material to be sealed, in a cost and functionally optimum manner, the outer wall (4) of the supporting body (1) has a wall section (7) offset inwards which is surrounded by the jacket (11), so that the outer wall (4) and the wall section (7), located radially further outwards, form a common outer surface (12, 13). The sealing lip and jacket (11) furthermore consist of different materials. The sealing ring has a very firm seat in the region of the supporting body outer wall (4) and, because of the jacket (11), also has good static sealing. <IMAGE>

Abstract: Pitch that is obtained from a condensed polycyclic aromatic hydrocarbon and the content of an optically anisotropic phase in which is substantially 100% is disclosed. This mesophase pitch has a H/C atomic ratio of 0.5 - 1.0, contains naphthenic carbon in an amount of at least 7% of the total carbon, and has a softening point of 180 - 400°C. Fibers melt-spun from this mesophase pitch can be converted to carbon or graphite fibers having high strength and modulus of elasticity by a heat treatment which consists of heating to a temperature of 250 - 300°C in an air atmosphere, then heating to 1,000°C or higher in an inert gas atmosphere. Such mesophase pitch is produced by polymerizing a condensed polycyclic aromatic hydrocarbon for 5 - 300 minutes at a temperature of 180 - 400°C and at a pressure of 5 - 100 atmospheres in the presence of 0.1 - 20 moles of HF and 0.05 - 1 mole of BF₃ per mole of the condensed polycyclic aromatic hydrocarbon.
