Abstract: PCT No. PCT/FI92/00112 Sec. 371 Date Dec. 9, 1992 Sec. 102(e) Date Dec. 9, 1992 PCT Filed Apr. 13, 1992 PCT Pub. No. WO92/19082 PCT Pub. Date Oct. 29, 1992.The invention concerns a method and equipment for the compensation of voltage increase in electrodes of a apparatus used to process dielectric materials. In the apparatus the electrodes are arranged parallel, at a constant distance from each other across the conveying path of the material to be treated. Electric power to the electrodes is supplied by connecting the adjacent electrodes to a opposite pole of a high frequency power source. In order to minimize the voltage increase in the electrodes, a reverse magnetic field is brought to influence with the magnetic field of each electrode, by arranging a return path for the electrode current at a suitable distance from the electrode and connecting these return paths to the return paths of the adjacent electrodes.

Abstract: A method in a mobile radio communication system for adapting the system and communication to prevailing traffic and performance requirements. According to the invention a mobile station inserts information on particular codes in its messages transmitted to a base station in response to an invitation message from the base station. The codes indicate whether a message is new or retransmitted and/or message age. The base station receives radio signals in time slots identified in its invitation message and estimates for each time slot based on radio signals received in the time slot whether the time slot is empty or busy, or whether the time slot is empty or correct. For each message received and understood the base station retrieves the code. The retrieved codes and the number of emty/busy/correct slots enable the base station to estimate prevailing system traffic and performance. Estimations on prevailing traffic and performance are used to control system parameters such as number of time slots following an invitation message.

Date Oct. 17, 1991.A low power OFDM signal may be transmitted in an environment where it is subject to interference from other transmissions, e.g. broadcast television services. In a receiver interference is reduced by ignoring information modulating OFDM carriers at the frequencies corresponding to the carriers of the interfering transmissions; adjacent channel interference is reduced by ignoring data on OFDM carriers at the band edges and interference from third order intermodulation products is reduced by the ignoring OFDM carriers affected. Image channel interference is reduced by using an intermediate frequency for a first mixing process in the receiver such that the image channel interference affects OFDM carriers at frequencies which are already being ignored by the receiver. Preferably no data is modulated onto OFDM carriers which are to be ignored by the receiver. Preferably the modulation of the OFDM carriers is arranged so as to produce a real baseband representation of the OFDM signal.

Title: Sonet receive signaling translator
Inventor: BAYDAR ERTUGRUL
IPC: H04J3/12
Filed: 1990-05-10
Granted: 1997-10-21
Abstract: The four signaling bits contained in the eight-bit SONET signaling bytes are read from the SONET signaling row and are converted to four parallel signaling bits for storage in a RAM in quasi SONET format, with sets of four A, four B, four C and four D bits for four consecutive channels being stored for an even and an odd tributary in one RAM memory row.  Storing sets of four of the same bit for four consecutive channels simplifies the RAM write operation.  A read-modify-write system is used for updating the RAM storage, wherein a row of RAM is read, modified by eight new signaling bits from two consecutive SONET signaling bytes, and is rewritten into the RAM.  New signaling bits are stored to accumulate eight new signaling bits for two tributaries prior to updating the RAM with the new bits for both tributaries.  The 32 signaling bits output during a RAM read operation are selectively multiplexed to output only four bits associated with a particular channel.

IPC: C01B33/38
Filed: 1990-09-10
Granted: 1995-07-18
Abstract: For producing crystalline sodium silicates having a layer structure, an SiO2/Na2O molar ratio of (1.9 to 2.1) : 1 and a water content of less than 0.3% by weight from a waterglass solution containing at least 20% by weight of solids, the waterglass solution is obtained by reacting quartz sand with sodium hydroxide solution at an SiO2/Na2O molar ratio of (2.0 to 2.3) : 1 at temperatures of 180 to 240°C and pressures of 10 to 30 bar. This waterglass solution is treated in a spray-drying zone with hot air at 200 to 300°C for a residence time of 10 to 25 seconds and at a temperature of the exit gas leaving the spray-drying zone of 90 to 130°C, to form a pulverulent amor-phous sodium silicate having a water content (determined as the loss on ignition at 700°C) of 15 to 23% by weight and a bulk density of more than 300 g/l. The pulverulent, amorphous, water-containing sodium silicate is introduced into  an  obliquely  arranged  rotary kiln  fitted with devices for moving solids and treated therein with flue gas in countercurrent at temperatures from more than 500 up to 850°C for 1 to 60 minutes to form crystalline soidium silicate. The rotary kiln is here insulated in such a way that its outside wall temperature is less than 60°C. Finally, the crystalline sodium silicate emerging from the rotary kiln is comminuted by means of a mechanical crusher to grain sizes of 0.1 to 12 mm.

Abstract: Poultry packed in a crate suitable for the transport of live poultry are passed into a chamber having an oxygen depleted atmosphere and held in the atmosphere for a sufficient period of time for the poultry first to lose consciousness and then to die as a result of the lack of oxygen in the atmosphere. The atmosphere typically comprises nitrogen or argon containing less than 1% by volume of oxygen. It is found that the birds so slaughtered exhibit less bone damage than poultry slaughtered by a conventional method including the step of electrically stunning the birds prior to slaughter.
