Abstract: In a Time Division Multiple Access (TDMA) cellular system, there is provided a mechanism for synchronization and equalization comprising: providing synchronization information (S/S) sufficiently removed from the start of a TDM slot so as to maintain the integrity of that synchronization information (S/S) at adjacent cells and providing that synchronization information (S/S) not so far removed from the start of the slot as to necessitate adaptive equalization of information preceding the synchronization information (S/S) for sufficiently reliable recovery. The equalization is further enhanced by providing, roughly mid-way between the synchronization information (S/S) and the end of the slot, additional information (CC) upon which equalization may retrain. Accordingly, equalizers perform retrospective, non-adaptive equalization of information preceding the synchronization information (S/S), perform adaptive equalization of information following that synchronization information (S/S), and retrain utilizing known bit-sequences elsewhere within the TDM slot; the additional information (CC) comprises known bit-sequences identifying cells.

Title: Picture carrier controlled automatic gain control circuit for cable television interdiction or jamming apparatus
Inventor: WEST LAMAR E JR
IPC: H04H20/00
Filed: 1990-12-05
Abstract: An off-premises negative or positive trap jamming cable television or interdiction system includes a picture carrier controlled automatic gain control circuit (231). A broadband television signal output of a variable gain device (230) is distributed by a radio frequency signal splitter (280) to a number of subscribers. A portion of the output of the variable gain device (230) comprising at least two contiguous television channels is passed to a power level detector (502). A detected power level is compared with a predetermined power level reference (504) for adjusting the gain of the variable gain device (230). The predetermined power level reference is set to equal the attenuation between the off-premises equipment and the subscriber premises plus the desired level at the entrance to the subscriber's premises. The power level of a jamming or interdicting signal for denying access to unauthorized television programs is set to fall within a predetermined range of power levels related to the predetermined power level reference.

Title: Synergistic tumor therapy with combinations of biologically active anti-tumor antibodies and chemotherapy
Inventor: HELLSTROM INGEGERD
IPC: A61P43/00
Filed: 1991-05-17
Abstract: The present invention relates to the use of combinations of antibody therapy and chemotherapy in the treatment of malignant disease. It is based in part, on observation so if the surprising effectiveness of combination therapy; several patients who had received the anti-tumor antibody L6 or MG21 achieved complete remission in response to subsequent chemotherapy, although the same patients had not responded to similar chemotherapy regimens prior to receiving L6 or MG21 antibody treatment. Embodiments of the invention, antiglycolipid antibodies such as, preferably, L6 monoclonal antibody or MG21 monoclonal antibody, are administered to patients who are subsequently treated with standard chemotherapy regimens. In preferred embodiments of the invention, chemotherapy is administered within several months of antibody treatment. It is suggested that the effectiveness of combination therapy may be attributable to antibodies at the tumor site which render the malignant cells more susceptible to the toxic effects of chemotherapeutic agents.

Title: Shoe with central clasp
Inventor: BERGER CHRISTOPH
IPC: A43C11/16
Filed: 1991-08-05
Abstract: ABSTRACT OF THE DISCLOSURE       The invention concerns a shoe, in particular a shoe for sport, leisure or rehabilitation purposes, with a centrally positioned clasp mounted on a dimensionally stable instep covering which can be moved towards or away from the instep. The clasp is designed so that it can be used with shoes having uppers made of material which is flexible with respect to tensional forces, i.e. with shoes which do not have dimensionally stable sheath-like uppers.  This is achieved by virtue of the fact that the centrally positioned clasp is fitted on a mounting plate which is attached to a flexible tongue.  The mounting plate is significantly smaller than the length of the instep, thus allowing substantial parts of the tongue to remain flexible.
