Title: Process for doping aqueous solutions with acrolein in biocidally active concentrations
Inventor: WERLE PETER
IPC: C02F1/50
Filed: 1991-12-02
Abstract: The direct dosing of aqueous solutions with acrolein as a microbiocide is problematic because of the associated laborious safety measures and the hitherto known use of reaction mixtures from the deacetalisation has proven not to be very economical. 
<??>According to the invention, aqueous solutions can be dosed in a simple, safe and economical manner with acrolein at a sufficient concentration level to be active as a biocide by cleaving acrolein acetals in the aqueous phase in the presence of a strongly acid deacetalisation catalyst into acrolein and the alcohol component, continuously removing the resulting acrolein from the deacetalisation mixture and transferring the acrolein into the aqueous solution to be dosed using an inert gas stream or a liquid jet pump with the aqueous solution to be dosed as the jet liquid.

Title: Method for fine tuning the resonant frequency of a filter in a combiner
Inventor: VICTORIN JOHN A
IPC: H03H7/46
Filed: 1991-12-19
Abstract: The invention relates to a method for fine tuning the resonant frequency of a filter in a combiner, which is provided for combining signals from several radio channels, to the carrier frequency of an input signal to the filter.      The power of the output signal from the filter is measured in a narrow frequency band around the carrier frequency of the input signal. Furthermore, the power of the signal reflected by the filter is measured in a narrow frequency band around the carrier frequency of the input signal.      Thereafter a measure of the ratio between the two power measurements is formed. The resonant frequency of the filter is adjusted so as to maximize this measure.

Filed: 1992-01-07
Abstract: A spinning nozzle for dry spinning a spinning solution containing a metal compound and an organic polymer compound by a blowing method. In the spinning nozzle, an air nozzle 6 has a rectangular-prism-like slit which is formed by opposing inner surfaces, extending in parallel to each other, of the projecting portion, which are formed at the front side, of a pair of cover plates 1,1, each of the projecting portion having a knife edge portion at its free end. Spinning solution supplying nozzles are composed of a plurality of linear pipes and are arranged in the air nozzle 6 in such a manner that they are in parallel to the parallel surfaces of the cover plates and are projected from the edges of the parallel surfaces. Air fed through a gas feeding port 5 and blown out as an air stream from the air nozzle 6, and streams of the spinning solution extruded from the spinning solution supplying nozzles form parallel streams. Further, the air stream in parallel to the spinning solution streams is sufficiently rectified so that it becomes contact with the spinning solution.      Accordingly, an amount of air used can be greatly reduced and fibers having excellent quality can be produced.

Abstract: TELEPHONE WITHOUT NUMBERS            Abstract Telephone is an apparatus people use it everyday. We know it needs a certain number of digits to dial( 7,6,or 8,.... depending on the telephone system of the specific regions,countries ). In this invention,a new telephone system and a corresponding telephone apparatus are designed so that when we want to make a phone call, instead of having to find the desired seven digits(or other numbers) from the brain memory or white pages/yellow pages,we can simply dial the name of the person and/or some supplemental identifications alphabetic and/or numeric string,which can be the address,the age,the city or some location specifications. Today the function of the communication local relay centre is to identify 7 digits,which is the simplest way. In this invention,the function of the local centre is to identify a location string,then get the corresponding 7 digits fromthe computer memory,then verify with the caller by sending message on the caller's phone small screen.until a unique matching is found see figure 2. An organisation and its internal divisions/departments are treated in the similar way as an individual person.

Abstract: Vêtement absorbant jetable (10, 10", 10"') pourvu d'une ceinture (12, 12', 12", 12"').  La ceinture peut faire partie intégrante (12", 12"') de la partie absorbante du vêtement, ou peut être amovible (12, 12').  Cette ceinture (12, 12") est arquée, et un de ses bords se prolongeant latéralement (16, 16") est plus long que l'autre bord se prolongeant dans le même sens (16, 16").  On obtient ainsi une ceinture mieux ajustée qui épouse plus discrètement la silhouette de l'utilisateur, et qui est moins perceptible sous l'habillement.  La ceinture (12"') peut présenter : une partie portée relativement haut sur le dos de l'utilisateur; des parties se prolongeant en diagonale vers le bas et le devant du corps; une partie portée relativement bas en avant, sous le ventre.  On obtient ainsi une ceinture (12"') qui n'entrave généralement pas l'amplitude des nombreux mouvements exécutés habituellement par  l'utilisateur.

Abstract: PRÉCIS Dans un système d'isolation servant à retarder les pertes de chaleur de l'intérieur vers l'extérieur en hiver et inversement en été, il est reconnu que d'une façon générale les panneaux rigides sont posés en about ou à feuilleure et quelques fois l'on applique un ruban adhésif sur les joints. Cette technique n'est pas très efficace en ce qui concerne le pare-air. Dans la présente invention, le joint périmétrique de chaque panneau est conçu de manière à s'emboiter à chacun des panneaux adjacents, par un système de languettes et rainures dissimulées et par des joints entrecroisés, dissimulés aussi, empêchant toute infiltration d'air à travers l'enveloppe de l'édifice. Un tel système peut s'adapter à toutes les formes d'un édifice ainsi qu'à différents accessoires traversant cette enveloppe comme les ancrages à maçonnerie. Ce nouveau type d'ancrage est conçu spécifiquement pour s'adapter au présent système. De plus, le périmètre de cette enveloppe est scellé au mur de fondation, aux portes et aux fenêtres, ainsi qu'aux murs et à la toiture à l'aide de membrane flexible.
Patent CA-2076940-A1 (CA)
Inventor: ROLL ULRICH
IPC: H05B41/233
Filed: 1992-08-26
Abstract: To eliminate the necessity for a saturated or air gap inductance to provide a feedback circuit for a self-exciting oscillator including two active electronic switches (T1, T2), for example MOSFETs, an auxiliary winding (HW1, HW2,....HW11) is inductively coupled to the resonance inductance (L2) present in the circuit for the discharge lamp (LP) anyway; and a pulse shaping - phase shifting network (R3, C3; R4, C4....), devoid of inherent resonance, coupling the auxiliary winding to the active switching elements.      The pulse shaping - phase shifting network is formed of a one or multiple-stage RC low-pass circuit, connected serially between the auxiliary winding and the control input, for example the gate, of the active switching element. The RC network can be constructed with variable elements, for example including PTC resistors, a varistor or the like, and may include a current source, protective circuits to protect against voltage peaks including Zener diodes.      The low-pass characteristics of the pulse shaping - phase shifting network permits switching of the active semiconductor switches after the maximum current flow.

Title: Change definition language for computer database system
Inventor: OLSON JACK E
IPC: G06F17/30
Filed: 1992-09-25
Abstract: A database application implemented on a computer includes a generic database management product (software) such as IBM DB2 along with a catalog defining the way the data itself is stored. The catalog is a definition of the tables, indexes, views, user authorizations, etc., that specify a user's particular application of the database management system. Access to the database via the catalog uses a structured query language or (SQL) which provides a way of expressing statements in a high-level language so the user will not be burdened with writing code to access the data itself. The structured query language provides statements for defining tables, indexes, views, etc., to be incorporated into the catalog. A database application (to fit a user's business) is generated and updated in a number of phases, such as design, development, test and production, and in each one of these phases a facility exists for making alterations in the database definition (catalog), all of which make use of SQL to implement the changes. According to a feature of the invention, a change definition language (CDL) is provided which is an extension of (and in the general format of) the structured query language. The change definition language allows all important alterations to be described, as changes to an existing definition, for example, and may be used by all phases of the development cycle. The CDL statements do not make the changes directly in the catalog, but instead work through SQL and another intermediate mechanism such as DB2 ALTER tailored to make changes using SQL. The changes expressed in CDL may be migrated to downstream phases and fed back to earlier phases by use of a batch of change statements expressed in CDL.

Abstract: A unique hardenable gold based alloy, especially a 14 karat alloy containing gold, silver, copper, zinc, cobalt and an alternative alloy additionally containing iridium. The alloy has a fine grained structure, a lower hardness in the soft condition, a nice yellow color and a capability to be hardened to an exceptional hardness value. The alloy contains approximately 58.3% gold (Au), between about 10% to about 14% silver (Ag), between about 2.5% to about 3.0% zinc (Zn), between about 0.2% to about 1.0% cobalt (Co) and the balance of the alloy being copper (Cu) with the special provision that the ratio of the weight percent amounts of copper to, the sum of the silver and two (2) times the zinc amount, [Cu/(Ag+2Zn)], has a value of between about 1.3 to about 2.5. The copper to silver weight percent ratio [Cu/Ag] of between about 2.0 to about 3.8, in combination with the ratio of copper to, silver + 2 x zinc, [Cu/(Ag+2Zn)] results in a gold alloy with a heretofor unachievable combination of a most desirable yellow color and an exceptional degree of reversible hardness. The alloy may also contain a weight percent amount of between about 0.003 to about 0.03 iridium (Ir) which results in a gold alloy with the above characteristics but also provides for an alloy having a very fine grained structure.

Inventor: BRUTON LEONARD T
IPC: H03B27/00
Filed: 1993-04-22
Abstract: A digital oscillator generates pairs of sampled sinusoidal signals having precisely established phase relationships, e.g., in near-perfect quadrature.  The digital oscillator has first and second, interconnected multiplying-integrating modules.  Each module has a multiplier for multiplying an input signal by a first coefficient, and a digital integrator for integrating the product over a period of time and thereby generating a different one of the sampled sinusoidal signals.  Setting the multiplier coefficients appropriately controls the amplitudes of the generated sinusoidal signals.  Likewise, the frequencies and phases of the sinusoidal signals are controlled in response to the values of the multiplier coefficients and to the period of integration.  In a preferred embodiment, the first module has a delay free-forward-path ("DFFP") integrator, and the second module uses a delay-forward-path ("DFP") integrator.  In the DFFP integrator, the forward path from input to output within the integrator is substantially delay-free, and a device provides a delay in a feedback path between the integrator input and output.  In a DFP integrator, on the other hand, a device provides a delay in the forward path, and the feedback path is substantially delay-free.  Other versions of the invention provide two pairs of quadrature-related sampled sinusoidal signals.
