Title: Sol-gel process for glass and ceramic articles
Inventor: POPE EDWARD J A
IPC: C03C1/00
Filed: 1990-12-14
Granted: 1996-08-20
Abstract: An improved sol-gel process is disclosed for fabri-cating large monoliths of silica or ceramic material, which are substantially free of cracks. Following forma-tion of the gel, but before the gel is dried, the gel is sub-jected to a hydrothermal aging treatment (50), in which it is heated in an autoclave to a temperature of between 100 and 300 °C, for a time duration of a at least about one hour. This hydrothermal aging treatment causes sili-ca (or ceramic) particles to migrate and fill small pores in the porous gel matrix, such that the average pore size increases and capillary forces encountered in the subse-quent drying step (70) are reduced to a point where cracking of the gel is substantially eliminated.

IPC: H04R3/04
Filed: 1991-12-13
Granted: 2000-01-25
Abstract: An audio signal processor (10, 12, 14) is disclosed for correcting harmonic and phase inaccuracies caused by the transduction, recording and playback of live audio signals. Operational amplifiers with fast slew rates and large bandwiths are used to implement a simple but effective circuit that can be reduced to a single chip.  Signal phase is continuously and automatically shifted as a logarithmic function of frequency to compensate for differences in propagation velocities, thereby reducing the spatial smear that is inherent in conventional loudspeaker designs. Harmonic frequencies present during a live performance are regenerated by the signal processor to restore realism to the reproduced audio signal.

Title: Safety device
Inventor: OSTROBROD MEYER
IPC: A62B1/06
Filed: 1993-11-26
Granted: 1998-01-20
Abstract: A safety device for preventing injuries to a worker as a result of a fall includes a housing which is intended to be mounted at an elevated position where the worker is working and a cable which is adapted to be connected to a harness or belt worn by the worker. The housing includes a spring driven drum therein which normally keeps the cable wound thereon but which allows the same to be withdrawn slowly from the housing as more cable is needed by the worker. A centrifugally operated brake senses an initial quick withdrawal of the cable from the housing which results from the worker falling and stops further withdrawal therefrom to thereby prevent the worker from falling further. A  manually operated crank mechanism by the housing allows a fellow worker to raise or lower the fallen worker to safety.

Title: Suction feed nozzle assembly for hvlp spray gun
Inventor: BURNS MARVIN D
IPC: B05B7/08
Filed: 1994-09-14
Granted: 2000-05-16
Abstract: For an HVLP paint spray gun, an improved suction feed nozzle assembly including a fluid tip and an air cap. The air cap directs an annular flow of atomization air around a fluid discharge orifice formed by a tubular portion on the fluid tip to aspirate fluid from the orifice and to atomize the fluid. The air cap also directs pattern shaping air at the atomized paint.  According to one feature of the invention, the spacing of the pattern shaping air orifices from the fluid discharge orifice is made sufficiently great that undue turbulence is not induced in the atomization air in the aspiration zone to maximize the fluid flow rate. According to a second feature of the invention; the fluid orifice in the fluid tip has a straight cylindrical portion and an expanding conical section connecting the cylindrical section to an annular flat front face of the tubular portion, of the fluid tip. The flat portion of the front face on the tubular portion is kept to a minimum to increase the particle distribution uniformity of the atomized paint.

Title: Electronic combination lock with closure and locking verification
Inventor: HAMILTON JAMES E
IPC: E05B47/00
Filed: 1995-02-03
Granted: 2005-04-26
Abstract: A lock is described which has the capability to generate or encrypt a close number which is then displayed to the operator of the lock to be used to verify the locking of the lock. This number must be reported to a central dispatch operation where it is compared with a number similarly generated using identical starting values and an identical encryption algorithm. Comparison of the two numbers, resulting in a compare equal will indicate that the lock has been locked since the lock encryption operation is dependent upon the repowering of the lock. The lock is repowered after it has been opened by rotation of the dial which will extend the bolt and through the rotation of the dial drive a stepper motor/generator to provide electrical power to the lock.

Abstract: Un décodeur auxiliaire d'informations vidéo servant à extraire un signal auxiliaire d'informations vidéo à partir d'un signal vidéo comprend un extracteur de données (230) et un dispositif (220) servant à ajuster le seuil de comparaison de l'extracteur de données (230). Le seuil de comparaison est ajusté rapidement jusqu'à détection d'une composante de référence du signal d'information auxiliaire pendant un intervalle d'affichage du signal vidéo, dans lequel l'information vidéo auxiliaire est censée apparaître. Une valeur est incrémentée après des intervalles d'affichage dans lesquels la composante de référence est détectée, et est décrémentée après des intervalles d'affichage dans lesquels la composante de référence n'est pas détectée. L'ajustement du niveau de comparaison cesse, lorsque la valeur est au moins un nombre prédéterminé. Le dispositif adapte rapidement le niveau de comparaison à d'importantes modifications d'amplitude à long terme du signal vidéo (par exemple à la suite d'un changement de canal) et maintient un niveau de comparaison constant quand des variations transitoires apparaissent dans l'amplitude du signal vidéo.

Inventor: TAN QIU
IPC: C07C37/74

Granted: 2002-05-28
Abstract: A process for the production of high purity and ultrapure bisphenol-A is provided in which 4-12 mol phenol is reacted with 1 mol acetone in a multistage suspended bed reactor column (41) comprising a plurality of perforated trays (42) and downcomers (43) both having screens (44 and 45) provided thereon and catalytic resin particles (46) placed on the screens (44 and 45) in association with the trays (42). In operation, all of phenol is charged to the uppermost tray and all the required acetone is introduced to the column (41) through several inlets (52) along the wall of the column (41). An inert gas rising through the trays (42) and the catalytic particles (46) thereon stirs the reaction liquid and particles (46) therein to form a suspension and strips water generated during the reaction of phenol and acetone.  Subsequently, the reaction mixture in the column is cooled to form adduct crystals of bisphenol-A with phenol and mother liquor, the adduct crystals are separated from the mother liquor, and phenol is removed from the adduct crystals. As a result of the stripping of water from the reaction mixture, high quality bisphenol-A can be obtained without the inclusion of concentration step before crystallization.
