Title: Method for producing glass article
Inventor: DANZUKA TOSHIO
IPC: G02B6/00
Filed: 1991-09-06
Abstract: A glass article is produced at a high production rate and a high yield by jetting a glass-forming raw material from a multi-port burner, synthesizing glass soot through hydrolysis of the glass-forming raw material, depositing the glass soot to form a soot preform, and heating and vitrifying the soot preform to produce a transparent glass article.  The glass-forming raw material is vaporized by heating it at a temperature higher than its boiling point and it is directly supplied to the burner.  The vaporized glass-forming raw material and a fuel gas for synthesizing glass soot are supplied to an inner port of the multi-port burner, and a fuel gas for heating the preform is supplied to an outer port of the multi-port burner.  The molar ratio of water generated by reaction of the fuel gas for synthesizing glass soot to the glass-forming raw material is from 2 to 3.

Title: Solenoid control of engine valves with accumulator pressure recovery
Inventor: WAKEMAN RUSSELL J
IPC: F01L9/14
Filed: 1990-09-24
Abstract: A system for accomplishing solenoid control of engine valves places a solenoid valve between an oil gallery and the lost-motion actuator for each valve. Although the basic phasing for the valves is established by a camshaft, the actual phasing is accomplished by causing the valve actuators to execute lost-motion. The amount of lost-motion establishes the actual opening and closing phase angles for the valves. The amount of lost-motion of each actuator is established by the timing of the opening and closing of the corresponding solenoid valve. Oil that is pumped from the actuators can be stored in an accumulator that is connected to the gallery for subsequent use in replenishing the actuators.

Abstract: Vulcanizable, mercaptan- and/or xanthogen-disulfide-regulated polychloroprene rubber are produced by emulsion polymerization of chloroprene and, based on polymerizable monomer used, 0 to 30 parts by weight ethylenically unsat-urated, other monomers copolymerizable with chloroprene in an alkaline medium by a process in which (1) 0.1 to 10 parts by weight of a tricyclic diterpene carboxylic acid containing at least two conjugated C=C double bonds per molecule, based on the polymerizable monomer used, and optionally (2) 0.1 to 5 parts by weight, based on polymerizable monomer used, fatty acid esters are used for their production.      The polychloroprene produced in accordance with the invention may be used for the production of vulcanized rubber articles. The polychloroprene rubbers produced by the process according to the invention have a minimal tendency to foul metal molds. The pollution of wastewaters by the process according to the invention is minimal. The well-known favorable properties of polychloroprene remain unaffected.

Title: Process and circuit for operating an inverter with n parallel servo components
Inventor: MICKAL HERMANN
IPC: H02M7/493
Filed: 1991-01-24
Abstract: Abstract The invention relates to a process for operating an inverter arrangement with n parallel servo components (2, 4, 6) in each case consisting of m converter valves (Tln, ..., Tnn), these n servo components (2, 4, 6) being supplied from a common direct-voltage source (Uz) at the input end and being combined with one another at the output end by means of a txansformer (10) followed by a filter  capacitor  circuit  (12),  and  to  a circuit arrangement for carrying out the process. According to the invention, each of the m drive signals (UAT1,...,UATm) generated is jointly supplied to n parallel converter valves (Tl1, Tl2, ..., Tlu and ... and Tm1, Tm2, ..., Tmn, respectively) of the n servo components (2, 4, 6) and an enable signal  (UFS1 and  ...,  and UFSm respectively)  is generated in each case precisely when each of the n parallel converter valves (Tl1, Tl2, ..., Tln and ... and Tml/ Tm2,... Tmn, respectively) generates an off signal (Uoff11, Uoff12, ... Uoff1n and ... and UOffm1, UOffm2, ..., Uoffnm, respectively) and each enable signal (UFS1 and ... and UFSm, respectively) enables a drive signal (UAT1 and ... and UATm, respectively) for n parallel converter valves (Tl1, Tl2, ..., Tln and ... and Tm1, Tm2,..., Tmu, respectively), switching in complementary fashion.  This  provides  an inverter  arrangement  having  only  one  regulating  and control device (8) for n servo components (2, 4, 6), the load current being distributed symmetrically to the n servo components (2, 4, 6).

Abstract: ABSTRACT OF THE DISCLOSURE     A new controlled release vehicle which acts by breakdown of the entrapping material upon hydration has been developed.  The preferred release vehicle is made of a carboxylated cellulose, e.g., carboxymethylcellulose, which is treated with a cross-linking agent such as aluminum ions and, preferably, hydrophobicity agent such as acetic acid.          The vehicle is broken down by a release agent, e.g., cellulase, which may be coated on the vehicle together with a coating agent, e.g., hydroxypropylcellulose.  The vehicle is dried, entrapping the molecule to be entrapped, e.g., an enzyme, and hydration activates the cellulase which breaks down the carboxymethylcellulose, releasing the entrapped molecule.
