Title: Protective arrangement for telecommunications line interface circuit
Inventor: STIBILA MICHAEL E
IPC: H01H85/00
Filed: 1990-04-06
Abstract: ABSTRACT OF THE DISCLOSURE       A circuit protection device designed to protect a pair of electrical circuits by fracturing at such time as an overcurrent condition has occurred in a first of the circuits, this novel device comprising a substantially flat substrate of non-conductive, frangible material upon which a resistive component and a fuse conductor reside in an adjacent relationship on a common surface. The resistive component is part of a first circuit, and the fuse conductor is part of a second circuit. The resistive component, at the time of an overcurrent therethrough, becomes hot and causes a heating of the near surface of the frangible substrate. The frangible substrate, as a result of the uneven heating of its opposite surface, elongating and then fracturing, the fracturing of the frangible substrate thereby bringing about a fracturing of the resistive component as well as a fracturing of the fuse conductor, thus to effect an interruption of the first circuit as well as a substantially simultaneous interruption of the second circuit. This novel device is admirably suited for protecting a subscriber line interface circuit.

Title: Phosphate salts of monomers for pbz and their use in preparing pbz polymers
Inventor: HARRIS WILLIAM J
IPC: C07C215/80
Filed: 1990-04-20
Abstract: ABSTRACT     PBZ polymers are synthesized by the reaction of AA- and BB-monomers.  The BB-monomer is conveniently synthesized and isolated as a phosphate salt having a uniform number of phosphate ions associated with each BB-monomer ion.  Such high purity monophosphate and diphosphate salts can be obtained by precipitating the monomer from an aqueous acid solution by adjusting the pH balance or from a mixture of phosphoric acid and a volatile, polar, saturated organic liquid at a rela-tively low temperature.     37,500-F

Title: Chair, in particular work or office chair
Inventor: KORN HEINRICH
IPC: A47C1/032
Filed: 1990-05-18
Abstract: A chair, in particular a work or office chair, the seat of which is variable in inclination and is pivotal in the forward region about a horizantal pivot shaft. A backrest is mandatorily, disproportionately variable in inclination as a function of the change in seat inclination. With increasing inclination of the seat, the backrest approaches the rear end of the seat. The pivot shaft of the seat is limitedly adjustable both downward and toward the backrest on the bearing block of the chair pedestal. The seat is pivotally connected to pivot levers, one end of each of which is fixedly attached and nonrotatable with respect to the backrest and the other end of each of which is rotatably supported on the bearing block. Synchronous motion with relative motion between the seat and backrest is achieved with an adjustment mechanism disposed only beneath the seat.      This mechanism is characterized in that the pivot levers are pivotally attached to the seat, spaced apart by approximately one-fourth the depth from the rear end of the seat. The ends of the pivot levers oriented toward the back rest have two segments located at approximately a right angle to one another. The backrest is firmly connected to the segments forming the free end of the pivot levers or is connected to them in a vertically incremental manner or infinitely adjustable manner. The opposite ends of the pivot levers are pivotally attached to the bearing block approximately beneath the middle of the seat and are at an obtuse angle of approximately 150° to 170°, facing toward the floor, from the adjoining segment of the pivot levers.

Inventor: KAZAWA TOHRU
IPC: H04J3/06
Filed: 1990-08-31
Abstract: This invention relates to a correlation transmission coder or a correlation code transmission system that utilizes the correlation transmission coder. This correlation transmission coder generates a transmission signal to be sent on a transmission line -- the transmission signal being determined, as with a partial response class 4 signal, by using already-transmitted data strings and data being transmitted -- by adding a specified length of frame synchronization pattern in each constant frame period. The correlation code transmission system includes a provision of means that reset or preset in each frame period registers that are used commonly by a transmission system and a precoder that makes up the coder. The system also includes a provision of means that insert immediately before the frame synchronization pattern internal data that is added to the transmission data by the transmission system and the precoder.

IPC: D21F3/10
Filed: 1990-12-06
Abstract: The invention concerns a suction roll (10) for a paper machine, on which the paper web is pressed towards the outer face of the roll mantle. The suction roll (10) is divided, in the axial direction of the roll, into at least three vacuum spaces (A1,A2,A3). In the interior of the suction roll (10), there are at least two partition walls (17a,17b), by means of which the suction space (13) is divided into separate zones of negative pressure. The lateral vacuum spaces (A1,A3) in the suction space can be subjected to a higher negative pressure than the vacuum space (A2) in the middle area of the roll, whereby the profile of negative pressure is formed such that the negative pressure increases across the width of the roll towards the lateral areas. The invention also concerns a method for producing a desired pressure profile for a suction roll. <IMAGE>

Patent CA-2033341-A1 (CA)
Inventor: CLAUSER JOHN F
IPC: G01P15/14
Filed: 1990-03-05
Abstract: The invention is a neutral atom (and/or molecule) matter-wave interferometer (and/or set of interferometers) that can be used as a ultra-sensitive inertial and/or gravity sensor. A pair of interferometers with different energies and/or  masses  can  perform  simultaneous  independent measurements of rotation and acceleration.Interferometers with paths that follow a figure-eight pattern yield a gravitational  gradiometer.  Diffraction  gratings  are employed as beam splitters. Such gratings may consist of apertures (S1,S2,G1,G2,G3,G4,G5,G6) in a sheet of solid material,   near-resonant  standing-wave  laser  beams (97,99,101), or crystal faces (179). Path curvature due to acceleration and rotation is canceled by magnetic and/or electric field gradients that produce an effective levitation  of  slow  atoms.  A  feedback  system  that maintains an interferometer phase null is employed with its error signal yielding the inertial effect signals.

Inventor: LEE YONG H
IPC: H01S5/183
Filed: 1991-02-25
Abstract: Abstract Top surface emitting, vertical cavity, surface emitting lasers depend upon emission through apertured top surface electrodes. Biasing current, accordingly peripheral to the laser as introduced, follows a path which comes toconfluence within the active gain region to effectively attain lasing threshold. The path is a consequence of a buried region of increased resistance which encircles the laser at or above the active region. The buried region is produced by ion implantation-induced damage with ion energy magnitude and spectrum chosen to produce an appropriate resistance gradient. Integrated, as well as discrete, lasers are contemplated.
