Title: Appliance collapsible for insertion into human organs and capable of resilient restoration, and device for collapsing same
Inventor: INOUE KANJI
IPC: A61F2/06
Filed: 1991-02-14
Abstract: ABSTRACT    An artificial body vessel to be inserted into a human organ is collapsed and introduced into a catheter, which is brought to a required position in the human organ, where the artificial body vessel is released therefrom.  A pair of foldable, elastic wire rings 10 are provided at the opposite ends of the artificial body vessel.  A plurality of connecting wire rings bridge the end wire rings 10.  A plurality of intermediate wire rings 12 bind and keep the connecting wire rings 11 transformed to a generally elliptical shape.  The end wire rings 10, the intermediate wire rings 12 and the connecting wire rings 11 are folded thereby to collapse the artificial body vessel 7.          The collapsed artificial body vessel 7 is inserted into a catheter.          At the objective position of the blood vessel the artificial body vessel 7 is released, so that the resiliency of the end wire rings 10, the intermediate wire rings 12 and the connecting wire rings 11 restores the artificial body vessel 7 to its original tubular shape.

Title: Adaptive equalizer for digital cellular radio
Inventor: DRIEDGER MARK E
IPC: H04B7/005
Filed: 1992-02-26
Abstract: The present invention provides a method of estimating parameters of a mobile radio channel which are used for providing the equalization and synchronization of the radio channel.  The channel is modelled as a discrete number of independent Rayleigh-faded propagation paths. First, the relative delay of each path is estimated, using maximum likelihood methods.  Using this information, the associated time-varying path weights are then determined using a least-squares fit.  This is sufficient information to estimate the impulse response of the channel.  The actual equalizer weights are then obtained by inverting the estimated channel impulse response.

IPC: C07K7/23
Filed: 1990-10-30
Abstract: Peptides which include unnatural amino acids and which either inhibit or promote the secretion of gonadotropins by the pituitary gland and inhibit the release of steroids by the gonads.  Administration of an effective amount of such peptides that are GnRH  antagonists prevents ovulation of female mammalian eggs and/or the release of steroids by the gonads. The antagonists may be used to treat steroid-dependent tumors, such as prostatic and mammary tumors. The peptides are analogs of the decapeptide GnRH wherein there is at least one residue of an unnatural amino acid in the 3-position, the 5-position, the 6-position and/or the 8-position. Such unnatural amino acids are useful in the synthesis of peptides and have the formula U*: where n is an integer from 1 to 6; Y is N-CN, N-CONHR9, S, O or CH-NO2; R9 is H, Ac, lower alkyl, aromatic or heterocyclic; X is NH, O, S, M1(CHq)pM2 or M1-(CH2)p'-M2(CH2)p''-M3, where M1 is NR10, O, S or CHR3 wherein R3 is methyl, ethyl, propyl, phenyl, pyridinyl, pyrimidinyl or purinyl; q is 1 or 2; p, p' and p'' are integers between 0 and 6; R10 is H, lower alkyl or the like, and M2 and M3 are M1, COOH, CONH2, COOR3 or CN; R1 is H, alkyl, modified alkyl, alkenyl, alkynyl, aryl or a direct bond to X; R2 is R1, OH, NH2, NHR1, or heterocycle.

Title: Lockable rotary handle operator for circuit breaker
Inventor: GRUNERT KURT A
IPC: H01H71/62
Filed: 1992-07-10
Abstract: A rotary handle operator for a circuit breaker with a linearly movable handle has a housing which is mounted over the circuit breaker handle. A slide carrying a rack engages the circuit breaker handle and is slidable within a chamber in the housing. The rack engages a pinion gear sector mounted on a rotatable shaft which extends through a cover on the housing. A rotating handle mounted on the shaft is rotated to linearly operate the circuit breaker handle or is positioned thereby when the circuit breaker trips. The handle may be locked in the off position by inserting the shackle of a lock through an aperture in a lever arm on the rotating handle to urge a pin on a spring biased locking piece within the handle lever into an aperture in the housing cover, or the shackles of several locks may engage a slot in a shroud surrounding the rotating handle to interfere with rotation of the handle out of the off position. An interlock for the door of a cabinet in which then circuit breaker may be mounted is incorporated into the rotary door operator.

Title: Disk drive memory
Inventor: DUNPHY ROBERT H JR
IPC: G11B5/012
Filed: 1991-02-05
Abstract: The disk drive memory (100) of the present invention uses a large plurality of small form factor disk drives (130) to implement an inexpensive, high performance, high reliability disk drive memory that emulates the format and capability of large form factor disk drives. The plurality of disk drives (130) are switchably interconnectable (121) to form redundancy groups of N+M parallel connected disk drives to store data thereon. The N+M disk drives are used to store the N segments of each data word plus M redundancy segments. In addition, a pool of R backup disk drives (130) is maintained to automatically substitute a replacement disk drive for a disk drive in a redundancy group that fails during operation.  The number N of data segments in each data redundancy group can be varied throughout the disk drive memory to thereby match the characteristics of the input data or operational parameters within the disk drive memory. Furthermore, a group of U unassigned disk drives (130) can be maintained as a stock of disk drives that can be powered up as needed and assigned to either a redundancy group or to the pool of backup disk drives.

Title: Nucleic acid amplification with dna-dependent rna polymerase activity of rna replicases
Inventor: DIMOND RANDALL L
IPC: C12Q1/68
Filed: 1991-12-31
Abstract: The present invention entails methods, and kits for carrying them out, based on the discovery that an RNA replicase, such as Q.beta. replicase, has DNA-dependent RNA polymerase ("DDRP") activity with nucleic acid segments, including DNA segments and DNA:RNA chimeric segments, which comprise a 2'-deoxyribonucleotide and which have sequences of RNAs that are autocatalytically replicatable by the replicase. The discovery of this DDRP activity provides methods of the invention for nucleic acid amplification wherein a nucleic acid, with a DNA segment with the sequence of an RNA that is autocatalytically replicatable by an RNA replicase, is provided as a substrate for the replicase. The replicase catalyzes synthesis, from the DNA segment, of the RNA, which the replicase then autocatalytically replicates. The invention entails use of the amplification methods in detecting nucleic acid analytes, as in nucleic acid probe hybridization assays.      Such assays of the invention include those wherein a nucleic acid analyte is hybridized with one or more nucleic acid probes, which include or are processed to generate a DNA segment which is amplifiable through production from the segment, catalyzed by the DDRP activity of an RNA replicase, of an autocatalytically replicatable RNA, which is autocatalytically replicated to provide an abundance of readily detectable reporter molecules.

IPC: A47K13/12
Filed: 1991-02-27
Abstract: For use with a toilet having a toilet bowl (12) and a lid (18) mounted to pivot between a closed position covering the bowl and an open position pivoted approximately 90· from the bowl, an apparatus (10) for automatically closing the lid includes a control mechanism (52) engageable with the lid for locking the lid in the open position when the lid is pivoted to the open position and a timer mechanism (53) for actuating the control mechanism to release the lid from the open position after the passage of a predetermined time. Where the toilet includes a toilet seat (17) pivotally mounted to the toilet bowl between the bowl and the lid and is pivotable from a closed position resting atop the bowl, a timer suspension system (130) temporarily suspends operation of the timer mechanism while at least a predetermined weight is applied to the seat in the closed position.

When the input binary data is negative, the data processing unit outputs data composed of bits from the least significant bit of the input binary data to the first "1" bit detected by the first "1" bit detecting unit, and an inverted bit or bits of a bit or bits of the input binary data more significant than the first "1" bit.
