Abstract: In order to achieve the spectrum economy and reduce the power consumption of a transmitter and reduce the error rate at a receiver and simplify receiver circuitry, at least one bit stream to be transmitted is quadrature modulated in a manner that the signal points do not define a trace on a complex amplitude plane which passes through the origin of the plane coordinates or in the vicinity thereof. The received signal is hard limited and frequency-discriminated to determine the instantaneous angular velocity of the received signal and is integrated to detect the phase variation between two consecutive received signals, and thereafter is decided with respect to the phase variation according to the decision threshold levels 0 and +/- pi  radians.

Abstract: Solid phase system for use in a ligand-receptor assay for the detection of a selected analyte in a fluid sample comprises a porous matrix in which microspheres are entrapped, the microspheres being bound with a receptor capable of capturing a target ligand. The system is for use in a multiple ligand-receptor assay for simultaneous detection of at least two selected analytes, distinct gps. of microspheres that are entrapped within discrete zones in the porous matrix, each gp. of microspheres being bound with a receptor capable of capturing a different target ligand. The following specific cases are claimed: one gp. of microspheres is bound with a receptor capable of capturing a target ligand; and one gp. of microspheres is bound with either (1) the target ligand or other receptor substance as a positive control; or (2) a substance incapable of capturing the target ligand without a bound component, as a negative control for the detection the analyte. Appts. is also provided.

Abstract: The invention concerns a procedure for the bleaching of pulp using an oxidating bleaching chemical containing chlorine. The essential features of the invention are that the chemical used in the oxidation stage has a chlorine dioxide content of at least 50 %, that the pulp is subjected to enzyme treatment either in conjunction with or before the oxidation, and that, after the oxidation and enzyme treatment, the pulp is treated with an alkali. The use of enzymes reduces the amount of chlorophenols and other forms of organically bound chlorine in the spent bleach liquor, simultaneously lowering its chemical oxygen demand.

Abstract: A protocol for authenticating a mobile customer unit to a service provider where signaling messages are encrypted and where voice communications can be encrypted. A service provider assigns to each mobile customer unit a unique "secret", along with other information such as a telephone number. At the pleasure of the service provider, a directive is sent to the mobile customer unit to create a shared secret datum based on the secret. The shared secret datum is created with the aid of a bit string that is sent for that purpose by the provider. A portion of the created shared secret datum is used for encrypting speech and the same or other portion of the created shared secret datum is used as an input to a process for creating a second encryption key. That key is employed in the mobile customer unit to encode those of the control signals generated by the mobile customer unit that affect the nature of the call in progress.

Abstract: A method for end-to end joining of paper rolls into a continuous core master is provided. The primary goal of the method is to produce usable paper roll cores from those returned for recycling after use. According to the aforementioned method, the ends of core sections are reworked into complementary shapes required for mating a joint, glue is applied to the complementary mating surfaces of the joint, the ends of the core sections are pushed in an axial direction abutting each other and the glue is set. The cross section of the cores is trued circular at least over the area of the joined core sections by applying a radial, compressive trueing force on the joint. The trueing force is also used for braking axial travel of the core sections during the joining of the core sections. An apparatus for implementing the method is also provided.

Abstract: Az eljárás során az olvadékkal töltött tégely tömegét
érzékelő mérőátalakító jeléből képezzük egyrészt az átmérőszabályozó
kör ellenőrző jelét, másrészt ugyanezt a
jelet hasonlítja össze egy komparátor áramkör alsó és felső
értékével. Ameddig a mérőátalakító jele az alsó és felső
komparálási szint közé esik, az utánadagoló kikapcsolt
állapotban van, az átmérőszabályozó pedig az irányítási
feladatnak legjobban megfelelő üzemmódban működik.
Ha a mérőátalakító jele eléri az alsó komparálási
szintet az utánadagolót a komparátor kimenőjele által
vezérelt kapcsoló bekapcsolja, egy másik vezérelt kapcsoló
pedig az átmérőszabályozót értéktartó üzemmódba
váltja. így az átmérőszabályozó kimenetén az alsó komparálási
szint elérésekor fennálló kimenőjelet biztosítja.
Az utánadagoló bekapcsolt állapotban marad mindaddig,
míg a mérőátalakító jele a felső komparálási szintet
el nem éri. Ekkor a komparátor áramkör által vezérelt
kapcsolók az utánadagolót kikapcsolják illetve az átmérőszabályozót
eredeti működési módjába váltják.
