Abstract: Disclosed is a method of making a catalyst precursor by aging an aqueous solution containing the monoperoxovanadium ion, VO(O2)<+>, until a vanadium-containing sol or gel is formed, and reacting said vanadium while in said aqueous sol or gel form, with an antimony compound that contains Sb having a valence of 3. In one embodiment, the VO(O2)<+> ion is made by reacting H2O2 with a vanadium compound. Also disclosed is making a catalyst by drying and calcining such precursor. When the drying is effected by spray drying a microspheroidal catalyst is produced. The catalysts useful for ammoxidation of propane are more attrition resistant than catalysts of the same empirical formula made by prior art methods.

Abstract: There is provided a self-actuating, variable pitch propeller having a plurality of blades. All of the blades are automatically movable about their axes (10) between a first, relatively lower pitch position (Fig 5) and a second, relatively higher pitch position (Fig 5), substantially simultaneously and equally in response to achieving a predetermined combination of propeller rotational speed and hydrodynamic loading on the propeller blades. The blades are releasably locked to prevent pivoting of the blades, at least in the lower pitch position, but preferably can be locked in both the high and low pitch positions. More preferably, a feedback force is transmitted from the blade to the locking means (112) to vary the locking force in response to the net turning moment on the blade. The locking means are released in response to the combined effects of centrifugal force generated by the blades and other portions of the propeller and the hydrodynamic loading on the blades.

Abstract: A BiCMOS process which provides both isolated and vertical NPN and PNP transistors with better performance characteristics and fewer additional steps than the prior art. The additional steps consist of masked implants with no changes in the thermal steps of the CMOS process. An N-well to contain the vertical PNP transistor is formed during the same step that the NPN vertical transistor collector is formed. The N base of the PNP transistor is formed by implanting an N type material. A P type material is implanted at a high energy of at least 300 keV (150 for doubly ionized Boron) to form a collector of the PNP transistor. A P region is then formed as an emitter of PNP transistor. The high energy P implant gives a peak at approximately 0.8um below the surface to form the equivalent of a buried layer (without growing an epitaxial layer after a P implant to form a buried layer as in the prior art). The advantages of a sharp profile of the high energy P implant are maintained by performing this step near the end of the process to prevent the profile from being flattened by subsequent thermal steps. A flat base structure improves the devices' performance and is preferably provided by doing the N base implantation early in the process and allowing the temperature of later steps to drive the implanted ions deeper to provide a flat profile.

Abstract: Very potent, stable, odorless, and phenol-free virucidal solutions are active at high dilution when used for surface decontamination of animate and inanimate objects. The virucidal compositions described are efficacious in a matter of minutes against both the lipophilic and the more resistant hydrophilic viruses. The three active ingredients in these virucidal compositions are the glutaraldehyde monomer in equilibrium with its hydrates and polymers, hydrogen-bonded glycol molecules to eliminate aldehydes odor, and an anionic surfactant of the alkyl sulfate, alkyl sulfonate, alcohol sulfate or alkyl aryl sulfonate type. A preferred anionic surfactant would be the Sodium Dodecyl Sulfate (SDS), which exhibits strong cidal synergism against the Herpes Simplex Virus type 1 when mixed at a concentration as low as 0.0005% in diluted glutaraldehyde aqueous solutions (0.0025%). Improved virucidal killing at higher dilutions of the same formula were observed with the more resistant Coxsackie B viruses. Because of the low concentration of active ingredients, these solutions exhibit a very low toxicity, making them suitable for topical applications as antiseptics.

Abstract: A vest system for generating cyclic fluctuations in intrathoracic pressure for use in cardiopulmonary resuscitation and non-invasive circulatory assistance. The vest is preferably provided with a two bladder inflation system. A high pressure bladder contacts the chest wall while a bias bladder is disposed between the high pressure bladder and the vest material. The bias bladder is pressurized to press the high-pressure bladder tightly against the chest wall so that cyclic inflation of the high-pressure bladder can generate large changes in intrathoracic pressure. The bias bladder is released periodically to allow the chest to expand for adequate ventilation. Air flow into and out of each bladder is controlled by sequencing large bore 3-way and 2-way solenoid valves and the rate of air flow into the high-pressure bladder is controlled by a variable resistor.

Abstract: A method and means is described for writing data on a recording medium, such as a disk or tape, containing servo samples in such manner that the number of servo samples is increased with a minimal increase in overhead (non-data) regions. The tracks on the medium are divided into a plurality of maxi sections, each of which contains all fields with servo and associated overhead information and also a data field. At least one micro servo section containing only a portion of said information is located within each data field. As each micro servo section passes by an associated recording head, writing and reading of data is temporarily interrupted, but resumed when the micro servo section moves beyond the head, in such manner as to require minimal resynchronisation of said data during reading. Using a phase continuous clock, data is written in both portions of a data field to either side of each micro servo section in one pass of the disk or tape relative to the head. The micro servo sections contain no timing reference address mark and require no data encoder/decoder flush or synchronisation byte to resume reading in the portion of the data field following each micro servo section. <IMAGE>

Abstract: The invention concerns an hydraulic machine, typically a submerged surface cleaner which comprises a body (10) having a liquid inlet (12) and a liquid outlet (14) and a conduit extending between the inlet and the outlet. A drive element (18) is supported in or adjacent to the conduit, with a clearance between the drive element and the interior of the conduit, in a manner permitting eccentric location and rotation of the drive element relative to the conduit. The conduit can be connected in a liquid flow path so that liquid passing through the conduit past the drive element, when the drive element is positioned eccentrically relative to the conduit, applies differential forces to the drive element to cause it to rotate relative the conduit. The rotation of the drive element is used directly or indirectly to drive the cleaner over a submerged surface.   <IMAGE>
