Title: Composite tube for membrane filtration
Inventor: REKERS CASPER J N
IPC: B01D69/10
Filed: 1994-01-07
Abstract: ABSTRACT         The invention relates to a composite tube for membrane filtration, comprising a finished tube or hollow-fibre tube which is suitable for membrane filtration and which, on the outside, is provided at least locally with reinforcing means, said reinforcing means consisting of a seamless tube which fits around the membrane filtration tube in a gripping manner and is made of liquid-permeable reinforcing material. More in particular, said reinforcing material consists of a knitted, woven or braided material, formed from glass fibres, aramid fibres, carbon fibres or combinations thereof. The tube of reinforcing material is expediently bonded to the finished membrane filtration tube by means of a thermosetting resin. The liquid permeability of the reinforcing material is preferably greater than or equal to that of the membrane filtration tube. A composite tube for membrane filtration according to the invention is found, in practice, to have a very long, effective service life. Moreover it is now possible to use tubes having a smaller internal diameter at acceptable costs.

Title: Engine Catalyst Aging System and Method for Aging Catalyst
Inventor: NICHOLS ANGELO H
IPC: G01M15/10
Filed: 1994-03-31
Abstract: The present invention provides a method for catalytic aging and a system for catalytic aging. The system modifies the operation of the engine while running in combination with a catalyst, making the engine a programmable gas generator for the catalyst. The present invention allows an operator to alter the operation of the engine by varying the signals to the engine's injectors, thereby altering the exhaust gas of the engine. While the engine is operating under user initiated injector signals, a simulated exhaust gas oxygen signal is provided to the engine control module. This signal results in maintaining the engine in stable operation while operating in an unstable state. In a preferred embodiment additional gases are injected into the exhaust gas being supplied to the catalyst. The system periodically returns all functions to the engine control modules allowing the establishment of new operating parameters for the engine.

Title: Microcrystalline phosphates as oxidation inhibitors for lipids, especially lipidic foods
Inventor: TODD PAUL H JR
IPC: A23D9/06
Filed: 1994-03-31
Abstract: ABSTRACT OF THE DISCLOSURE Solid phosphate particles,  less than 38 microns in size on their largest dimension, are shown to be effective oxidation retardants for fats and oils,  and especially fatty and oily foods and ingredients of foods.   Their suspensions in a lipid in which they are insoluble are especially useful.  They greatly enhance the effectiveness of natural antioxidants,  and are therefore particularly useful in making natural antioxidant systems at least as effective  as  the  synthetic  antioxidants  now  commonly employed.

Inventor: KAPLAN SAMUEL
IPC: C02F1/70
Filed: 1993-01-13
Abstract: The invention relates to Proteobacteria that show unusually high level resistance to a wide range of metal oxides and oxyanions and to methods using selected Proteobacteria subgroups for efficient reduction of certain metal oxides and oxyanions to the free metal. High level resistance was shown to be affected by growth conditions, and was observed in facultative photoheterotrophs such as Rhodobacter sphaeroides grown either chemoheterotrophically or photoheterotrophically. The disclosed methods are adaptable to the production of hydrogen from cultures of Peoteobacteria grown in the presence of tellurite class oxyanions with carbon dioxide and nitrogen as carbon and nitrogen sources.

Title: Baby stroller with removable wheels
Inventor: BAECHLER PHILIP A
IPC: B62B9/08
Filed: 1994-09-14
Abstract: An all terrain baby stroller using an axle assembly that allows the rear wheels to be easily and quickly mounted and removed from the stroller frame without tools. The axle assembly has each rear wheel rotatably mounted on an outward end portion of a stub axle. A tubular rear axle defines a cylindrical interior chamber with an outward end opening sized to slidably receive the stub axle inward end portion therethrough for positioning of the stub axle inward portion coaxially within the interior chamber. When so positioned, a circumferential groove of the stub axle inward end portion is positioned within the interior chamber. The tubular sidewall of the rear axle has an aperture positioned axially inward from the interior chamber outward opening and at a location to coincide with the circumferential groove. A lock pin is carried by a strip spring and is movably disposed in the sidewall aperture for selective movement between an engagement position and a disengagement position. In the engagement position the pin extends into the interior chamber and into the circumferential groove of the stub axle inward end portion to prevent axial withdrawal of the stub axle from the interior chamber. When in the disengagement position, the pin is sufficiently clear of the circumferential groove to permit the stub axle inward end portion to be axially inserted into and removed from the interior chamber.

Title: Digital demodulation circuit
Inventor: WADA YOSHIO
IPC: H04L1/20
Filed: 1994-03-09
Abstract: A clock reproducing circuit which can generate a good demodulation signal by detecting the timing point of the demodulation in an extremely short period of time; a digital demodulator which uses this clock reproducing circuit; a device for estimating a bit error rate of which deterioration of communication efficiency is limited to the extremity; and an AFC circuit which is capable of correcting a frequency drift in the correct direction exactly even when the frequency drift is great. The digital demodulator demodulates a signal detected by detecting a modulated wave by a given detector in accordance with timing clock signals. The demodulator comprises means for detecting the correlation of every two extraction points adjacent to each other by sampling a signal in the process of demodulation at a plurality of extraction points predetermined for every unit data cycle (symbol cycle); means for comparing the sizes of the correlations detected by the correlation detecting means, determining two pairs of extraction points of the greatest and second greatest sizes of correlation, and generating timing clock signals in accordance with the determination; and means for shifting the phase of signal in the process of demodulation in order to equalize the correlation sizes detected by the two pairs of the extraction points. The device for estimating a bit error rate detects the correlation of every two extracted points adjacent to each other by sampling a signal in the process of demodulation at a plurality of extraction points predetermined for every unit data cycle (symbol cycle), and estimates the bit error rate in accordance with the distribution of the detected correlations. Furthermore, in the AFC circuit, the frequency drift of the modulated wave is corrected by comparing the bit error rate estimated by the said bit error estimating device and the measured bit error rate.
