Title: Method and apparatus for ultrasonic leak location
Inventor: KUNZE ULRICH
IPC: G01M3/24
Filed: 1993-08-18
Abstract: Abstract of the Disclosure:          A method for ultrasonic leak location includes showing sound levels at various measuring locations along a measurement segment, with a bar diagram.  The same bar diagram is added again to the bar diagram.  A particular sound level having the highest value and being located the most in the middle of the placed together bar diagrams is picked out.  A segment around the associated pickup positions having one complete set of pickup positions is picked out.  Two compensating straight lines for that set having an intersection being ascertained to identify the leakage position are determined.          Another method includes providing at least a sound level having a position substantially facing the leakage position with a correction value.  An apparatus for ultrasonic leak location includes a number of ultrasound pickups being disposed along a measuring segment.   Amplifiers and compo-nents forming an effective value connect a data processing system to outputs of the ultrasound pickups.  The data processing system forms a placed together representation of two bar diagrams.  In another apparatus, the data processing system stores correction values for the sound levels and corrects the sound levels accordingly.
Patent CA-2109632-A1 (CA)
Inventor: GAGLIARDI UGO O
IPC: H04L47/76
Filed: 1991-05-24
Abstract: An ISDN gateway (GW, 100) dynamically allocates bandwidth by monitoring traffic at each destination queue and in response allocating or deallocating virtual B-channels. A long term allocation (LTA) algorithm is executed during usual traffic conditions to determine when, and for how long, virtual B-channels are to be allocated. During transient conditions, the gateway (GW, 100) executes a short term allocation (STA) algorithm. Bandwidth utilization is optimized by packaging data packets into trains that are transmitted to the destination when the train is complete and upon satisfaction of other conditions. Each train undergoes data compression by execution of a suitable compression algorithm.

Title: Polymers derived from ethylene and 1-butene for use in the preparation of lubricant dispersant additives
Inventor: EMERT JACOB
IPC: C10M129/92
Filed: 1993-12-09
Abstract: The invention pertains to oil soluble copolymers derived from ethylene and 1-butene which have a number average molecular weight between about 1,500 and 7,500, at least about 30 percent of all polymer chains terminated with ethylvinylidene groups, and ethylene-derived content of not greater than about 50 weight percent, and which form solutions in mineral oil free of polymer aggregates, as determined by light scattering measurements. Lubricating oil additives, particularly dispersants, produced by the functionalization and derivatization of these copolymers have enhanced performance (e. g., improved dispersancy and pour point) in lubricating oil compositions, attributable in part to the combination of properties characterizing the copolymers.

Title: Dry compositions for preparing submicron emulsions
Inventor: FRIEDMAN DORON
IPC: A61K8/06
Filed: 1993-02-17
Abstract: The present invention relates to dry, stable compositions which can be reconstituted to form pharmaceutical or cosmetic emulsions, and to methods for making such compositions. An emulsion is formed from about 0.2 to 25 weight percent of a first component of an oil, about 0.1 to 5 weight percent of a second component of an emulsifier, about 0.25 to 25 weight percent of a cryoprotectant of an amino compound, such as one or more amino acids, peptides or protein hydrolysates, and an aqueous component, wherein the amino compound is present in an amount that is equal to or greater than that of the first component. Optionally, a co-emulsifier, a suspension agent, a preservative, an antioxidant and a drug can be added to these emulsions. Thereafter, the emulsion is lyophilized to form dry compositions that have from about 40 to about 90 weight percent of the amino compound; from about 0.1 to about 20 weight percent of the emulsifier; and from about 0.2 to about 40 weight percent of the oily component. By combining the dry composition with an appropriate quantity of an aqueous liquid, the composition is reformed as an oil-in-water emulsion.

IPC: C10G2/00
Filed: 1993-02-24
Abstract: A method of conducting a continuous multi-phase catalytic reaction such as the conversion of syngas to higher hydrocarbon fuels. Gaseous reactants are introduced via a gas permeable plate (15) into a slurry (16) which includes the product and a finely divided catalyst. The liquid product is separated from the remainder of the slurry by means of a filter unit (13) including a filter member (22). A pressure differential is established across the filter member (22) by means of a constant level device (23) within the filter unit which maintains a level of filtrate (32) within the filter unit (22) below the level of the slurry (16). The slurry (16) is maintained in a constant state of agitation by the introduction of the gaseous components as a steam of bubbles. Fluctuations in the pressure differential across the filter member (22) prevent the filter member from clogging, and the gas space (28, 29) is above the filtrate (32) and the slurry (16) are in communication.

The rotating member is disposed between a slicing blade in substrate, negative air pressure is applied to the rotating transfer member to cause individual material slices to adhere to the outer surface of the transfer member in the same pattern in which they are slices from the food supply and to leave the outer surface of the transfer member in the same pattern thereby permitting, in effect, the "printing" of alternating layers of food slices on the substrate.  The apparatus has particular utility in the production of premade food set ups having a plurality of alternating layers.

Title: Voice activated data rate change in simultaneous voice and data transmission
Inventor: CHAPMAN JOSEPH Q
IPC: H04L27/34
Filed: 1994-09-22
Abstract: Voice Activated Data Rate Change in Simultaneous Voice and Data Transmission Abstract A simultaneous voice and data modem performs "voice-activated" data rate changes to improve the transmission quality of the voice signal. In particular, when the simultaneous voice and data modem detects that a local telephone set has gone "off-hook," the simultaneous voice and data modem selects a signal space with a lower symbol density, which, although resulting in fewer bits per symbol, provides for a higher quality voice transmission.
