Title: Sheet-feeder
Inventor: SAUER HARTMUT K
IPC: B65H1/06
Filed: 1991-03-28
Abstract: DE LA RUE GIORI S.A.              LAUSANNE/SWITZERLAND                 ABSTRACT                       SHEET-FEEDER            The  sheet-feeder  (B),  designed as a buffer store, has a magazine (24) for receiving vertically stacked sheets  and having a base (26), which leaves free an edge strip (R) of the sheet stack (S). Along this edge strip there moves  an endless  belt  (18),  articulated  on which are separating elements (1), provided  with  a  curved  suction  surface, followed by a plurality of spacers (11). The edge strip of the  lowermost  sheet  is  bent  away  downward  from  the remaining stack as it is sucked against the curved suction surface, and has the following spacers engage over it,  on which the remaining stack is supported.  After  passing of a separating element by the edge strip,  this  edge  strip bears  against  the  undersides  of the spacers, bent away completely from the remaining stack. From  this  position, in which the endless belt (18) is briefly at a standstill, the edge strip is fed by adjustable suction heads (31)  to a  conveyor belt (35), the grippers (37) of which draw the lowermost  sheet  out  from  underneath  the   stack   and transport it away.
Patent CA-2039718-A1 (CA)
Inventor: ROSSI JOHN J
IPC: C12N9/00
Filed: 1990-06-05
Abstract: This invention provides chimeric DNA/RNA catalytic molecules useful to cleave RNA sequences. The invention specif-cally provides two different chimeric DNA-RNA-DNA-RNA-DNA catalytic molecules which are targeted to cleave HIV-1 RNA sequences. These chimeric molecules include DNA sequences which flank a catalytic RNA enter. Interaction with the HIV-1 substrate RNAs is achieved by Watson-Crick base pairing of the DNA  flanking sequences with HIV-I RNA. The catalytic ribonucleotide center cleaves the phosphodiester bond of the substrate HIV-I  RNA at the expected location.

Abstract: ABSTRACT OF THE DISCLOSURE       A method is disclosed for eliminating the troublesome need to select and erase messages one by one which are stored in a memory of a radio pager.  A multi-function switch is provided via which  he pager can be switched on and off.  A controller of the pager determines if each of messages stored in the memory has been retained in the memory for more than a predetermined period of time.  Then, a message is erased in the event that one of: (A) the message has been stored in the memory for more than the predetermined time period and the multi-function switch is operated in a manner which changes the on/off status of the pager; and (B) (i) the message has been stored in the memory for more than the predetermined period of time and the pager is in the power on status, or (ii) the message has been stored in the memory for more than the predetermined period of time when the pager is switched on after being switched off.

Title: Ribozyme compositions and methods for use
Inventor: ROBERTSON HUGH D
IPC: C12Q1/70
Filed: 1990-09-25
Abstract: Ribozymes, sequences cleaving RNA, derived from sequences present in the hepatitis delta virus, have been engineered for greater specificity without increasing size. The specific ribozyme sequences are useful as reagents for cleaving RNA for experimental studies as well as antiviral therapies. Examples demonstrating the targeting of these sequences against HIV and Crohn's disease are described in detail. The sequences are also useful as diagnostics for the detection of hepatitis delta virus in tissue and fluid samples, as in blood banking, as well as in isolation and characterization of new viroids having ribozyme activity, using an RNA  specific hybridization method. Based on analysis of the two domain structure of the hepatitis delta virus, it is possible to construct a vector for expression of non-hepatitis delta virus proteins in mammalian cells.

Inventor: AOKI KAZUHIRO
IPC: G11B7/126
Filed: 1992-07-23
Abstract: Disk recording/reproducing apparatus has a first switch that outputs, during operation in the reproducing mode, the address signal and data signal alternately, and during either the recording or erasing mode, a reference voltage.  A second switch outputs, during the address signal period, the address signal obtained from a amplifier, and, during the data signal period, the output signal obtained from the first switch. Thus, during the recording or erasing mode of operation, the second switch will not produce the data signal.  The invention has the advantage of avoiding the previous need for an automatic gain control circuit in such apparatus.

Abstract: AN IMPROVED TUBELESS SHIELD AND ASSEMBLY                 Abstract A tubeless inner tire or shield 14 provides for easy assembly of the shield 14 into the outer tire 12 and over the rim 16 as compared to previous designs. The beads 43 in the shield comprise stranded filaments and the bead portion 40,42 of the shield 14 has increased flexibility.  The increased flexibility of the bead portion 40,42 eliminates kinking of the shield 14 upon assembly which could prevent the shield 14 from properly sealing against the rim 16.  Air passageways 44 between the inner shield 14 and outer tire 12 are provided on the shield 14 near the bead portion 42.  The air passageway 44 includes  a protrusion 50 extending from the surface of the shield and has an inclined radially inner surface 58.  The inner surface 58 is at an angle of 25° to 60° relative to a plane perpendicular to the axis of rotation of the inner shield 14.  The inclined inner surface 58 of the protrusion 50 facilitates the assembly of the inner tire 14 and the outer tire 12 on a rim 16.

Title: Carrier regenerating device correctly operable in mobile satellite communication
Inventor: IWASAKI MOTOYA
IPC: H04L27/22
Filed: 1993-02-16
Abstract: Supplied with an input signal into which a carrier signal is modulated at a frame period by a data signal and unique words periodically interspersed throughout the data signal, a demodulating circuit (14) demodulates the input signal into a demodulated signal.          A frame synchronizing circuit (23) produces an aperture signal which defines an aperture interval determined by the frame period when the demodulated signal has a level which is lower than a predetermined threshold level.          Responsive to the aperture signal, a cross-correlating circuit (24) calculates a cross-correlation coefficient between the demodulated signal and a locally known unique word.  By the use of the cross-correlation coefficient, a phase error calculating circuit (25) calculates a phase error between a reproduced carrier signal reproduced from the demodulated signal and a regenerated carrier signal which is a correct regeneration of the carrier signal.          By the use of the cross-correlation coefficient and the demodulated signal, a frequency error calculating section (31-35) calculates a frequency error between the reproduced carrier signal and the regenerated carrier signal.  A carrier regenerating circuit (15) makes the reproduced carrier signal become the regenerated carrier signal in accordance with the phase error and the frequency error.

A bias winding is also wound on the magnetic core.  Either the bias winding is coupled in series with a bias inductor, or, alternatively, the main and bias windings are configured on the magnetic core as a cross-field inductor.  A bias circuit supply provides dc or relatively low-frequency ac current to the bias winding in order to vary the permeability of the magnetic core, and hence the inductance of the main winding, thereby tuning the starting circuit.
