Abstract: ABSTRACT OF THE DISCLOSURE    A method for increasing the zeolite content of high zeolite content clay derived microspheres obtained by reacting porous precursor microspheres with a sodium silicate solution in the presence of seeds to crystallize zeolite Y in situ in macropores of precursor microspheres composed of a mixture of metakaolin and kaolin calcined to undergo the exotherm.  The increased zeolite content is achieved by increasing macroporosity of the precursor microspheres and increasing the content of metakaolin in the precursor microspheres.  The increase in zeolite is associated with an increase in catalytic activity and unexpectedly improved selectivity.

Filed: 1989-11-03
Abstract: An apparatus and method for depositing liquid material onto a workpiece in the form of a deposit having a desired conformation wherein the material is discharged under pressure from the nozzle of a dispensing gun which can be manipulated by a robot to lay the deposit according to a programmed pattern on the workpiece. One or more gas jets is directed toward the material after the material is discharged from the nozzle to impart a desired conformation to the material deposited on the workpiece.      The flow rate of the gas jets is controlled in accordance with the liquid flow rate, and/or a toolspeed signal from the robot to maintain substantial uniformity of the conformation of the deposit and/or in accordance with an auxiliary signal to permit selective alteration of the conformation of the deposit.      Disruption of a desired conformation due to irregularities in the manner liquid material is pumped to the dispensing gun is avoided by sensing occurrence of the irregularity and adjusting the flow rate of the gas jets in timed relation to the manifestation of the irregularity at the liquid discharge nozzle.

Title: Process for Ion Exchange on Glass or Glass Ceramic
Inventor: KIEFER WERNER
IPC: C03C21/00
Filed: 1989-11-08
Abstract: A process for ion exchange at the surface of glass or glass ceramic is described, in which the ion exchange is carried out by means of a solid layer mainly consisting of one or more salts which do not melt at the exchange  temperature  and  contain mono-  or  divalent cations.  The layer can be applied to the glass as a dispersion in water or as an organic dispersion medium. Preferably, its thickness is 0.02 to 2 mm and the salts have a particle size of less than 60 µm.  Despite the solid reaction, the ion exchange proceeds at a surpris-ingly rapid rate and leads to products having highly reproducible properties.

Abstract: A method of producing enhanced radial texture in zirconium alloy tubing suitable for use in forming cladding for nuclear fuel rods is provided. The tubing production method described herein employs a combination of mechanical expansion and heat treatment steps in the final stage of tubing formation to produce a single peak radial texture in the tubing, thereby imparting enhanced resistance to pellet-cladding-interaction to the finished tubing. The tubing is preferably processed to a diameter within less than about 10 to 20% of the desired final diameter, annealed, and expanded less than about 10 to 20% to the desired final diameter, thereby producing a unique radial texture in the finished tubing. In an alternative method, the finally expanded tubing is subjected to a final recrystallization anneal to produce a significantly enhanced split radial texture.

Patent CA-2029926-A1 (CA)
IPC: H04B1/707
Filed: 1990-11-14
Abstract: In a phase demodulator is received a signal of which the carrier is phase-modulated by a digital pseudorandom sequence itself phase-modulated by a data signal. A frequency close to that of the carrier is locally modulated by a sequence identical to the received sequence. The received and local signals are mixed into a filtered signal with an intermediary frequency band. A repetitive double integration step of the signal filtered into an integrated signal is used and is compared with a threshold in order to quantify the correlation between the received and local signals. Firstly, the local frequency  varies according to a few discrete values spread over the uncertainty range of the carrier corresponding to intermediary frequencies in the vicinity of the filtering band. At each discrete frequency value, integration steps are carried out for half-bit local frequency shifts. Synchronization of the sequences is acquired in response to an integrated signal exceeding said threshold at the end of an integration step. Then, the value of the carrier frequency is estimated by the average of numerous discrete local frequencies corresponding to favourable integration steps  and  included  in  a  band  centering  on  the  frequency  found  during synchronization of the sequences. The invention also relates to the closed-loop controlling of the amplification gain in correlators of the demodulator.
