Title: Apparatus for attaching labels or the like to packs
Inventor: FOCKE HEINZ
IPC: B31B50/62
Filed: 1991-01-11
Granted: 2000-08-15
Abstract: Cigarette packs (20) are often provided with a (tax) label (26) which extends across an end face (23) and adjoining pack faces. The process of attaching the label (26) has to be integrated into the complex flow of production. For this purpose, the label (26) is held ready in front of a mouth-piece opening (inserting opening 32) in a transverse plane, such that the label is folded round the pack (20) in a U-shaped manner when the pack passes through the mouthpiece opening. The packs (20) are transported in tight arrangement, such that the end face (23) of one pack (20) abuts the bottom (35) face of another pack (20) being in front.      The label (26) is thus "clamped" between two adjacent packs (20) and therewith additionally fixed in position. The labels (26) are introduced into the continuous feed flow of the packs (20) and of the pack channels (31) for receiving the packs via a stationary label dispenser (84), such that the labels (26) are held ready in front of the inserting opening (32) of a pack channel (31) and are folded in a U-shaped manner by the insertion of the pack (20) into the pack channel.

Granted: 1996-03-26
Abstract: Apparatus and method for popping high yield popcorn using a bag having a substantially rectangular cross section as manufactured using a conventional bag machine.  A base supports the bag on edge with at least one joining panel being inclined such as, for example, at 45.  Whether the bag is initially unfolded or unfolds as a result of internal pressure caused by some kernels popping, a horizontal elongated V-shaped trough is formed as the lower-most region of the bag due to the supporting orientation of the base.          Kernels form in a clump in the nadir of the trough thereby enhancing the yield of the popping, and kernels disturbed from the clump by popping kernels are directed back to the clump by the inclined walls of the bag.

Abstract: A method and apparatus for modulating and demodulating an MCM television signal is described which is particularly useful in proposed "simulcast" HDTV terrestrial broadcasting. The MCM spectrum of the television signal is shaped using weighting coefficients which are derived from either an idealized NTSC signal or an actual NTSC co-channel signal. These coefficients are used to shape the respective MCM carriers to provide an energy distribution in the MCM signal which provides greater degree of robustness with a minimum degree of co-channel interference to and from an NTSC co-channel signal. The instant invention further takes advantage of the interference characteristics of composite television signals described above, to position the placement of the MCM carriers in frequency, to minimize interference with an NTSC co-channel signal. Several methods of deriving the weighting coefficients are described including an adaptive approach whereby the characteristics of the interfering NTSC transmission are received and the instantaneous NTSC spectrum calculated therefrom and weighting coefficients assigned accordingly. These coefficients can be transmitted to a receiver to update its coefficient table.

Title: Precoding of signature sequences for cdma systems
Inventor: WEERACKODY VIJITHA
IPC: H04W72/04
Filed: 1993-07-19
Granted: 1997-12-23
Abstract: A technique for reducing multiple access interference (MAI) experienced by receivers of transmissions from a transmitter, e.g., a base station, in a direct-sequence code division multiple access communication system, e.g., a cellular radio system, is disclosed. The technique provides for the precoding of user signature sequences for use in spreading information signals to be transmitted. The use of precoded signature sequences significantly reduces the average level of MAI experienced by the receivers. Despreading of received signals by receivers may be accomplished with the original (i.e., non-precoded) signature sequences. Thus, no changes to receivers are required. The technique includes a feature for determining a set of sequences for both transmitter and receiver from a smaller set of orthogonal sequences.

Title: Method of selecting the most desirable code search mode in a pager in the case of frame async
Inventor: KURAMATSU HIROYASU
IPC: H04L7/04
Filed: 1993-11-03
Granted: 2000-03-21
Abstract: In the event that a radio pager falls into frame async while receiving information, an appropriate code search mode is desirably selected. Firstly, a controller of the pager checks to see if a bit sync indicating signal obtained from a bit synchronizer demonstrates bit sync. If the bit sync indicating signal indicates bit synchronization, the controller selects an operation mode for searching for synchronization code (SC). On the other hand, if the bit sync indicating signal indicates bit async, the controller selects a preamble code search mode. Accordingly, in the case where the pager becomes out of synchronism and immediately thereafter restores same during information acquisition, the pager is able to successfully obtain subsequent information by means of very simplified arrangement.

Abstract: Expression of mammalian target genes is achieved by employing chromosomal target DNA, either native primary cells or YACs in a yeast host, where the YACs include a fragment of a mammalian chromosome, the fragment comprising the target gene. Employing homologous recombination, an amplifiable gene is integrated into the mammalian fragment at a site to allow for amplification. In the same step, or one or more steps, as desired, the mammalian gene and/or the transcriptional system may be modified by in vivo mutagenesis. The resulting construct from homologous recombination may then be transformed into a mammalian expression host and integrated into the host genome, either randomly or by homologous recombination. The amplifiable gene may then be amplified by an appropriate agent providing for multiple copies of the.target gene and the expression host grown to provide for high yields of the desired wild-type or modified protein.
