Inventor: CONNAN PATRICK ANDRE
IPC: B65B3/16
Filed: 1997-06-11
Abstract: L'invention concerne un appareil et un procédé pour le remplissage d'un récipient à plusieurs compartiments avec plusieurs matières coulantes. Le récipient peut être un tube de dentifrice à deux compartiments, ou un récipient à adhésif à deux compartiments, par exemple. Le récipient (20) contient un élément de séparation intérieur (20), le divisant en plusieurs compartiments (22, 24) et l'élément de séparation doit permettre d'introduire des buses d'approvisionnement (36, 40) dans les compartiments respectifs. Dans un mode de réalisation, l'élément de séparation est positionné par des sondes (30, 32) introduites dans le compartiment et la rotation relative entre le récipient et les sondes entraîne le positionnement de l'élément de séparation par les sondes. Dans un second mode de réalisation, des buses d'injection d'air émettent des jets d'air pour positionner l'élément de séparation. Dans un autre mode de réalisation, une charge électrostatique est induite dans la paroi du compartiment et dans l'élément de séparation et, puisqu'ils présentent des charges similaires, la paroi du compartiment et l'élément de séparation se repoussent, ce qui positionne l'élément de séparation. Dans un autre cas encore, une buse d'injection d'air et d'aspiration (30d) est introduite dans l'un des compartiments, et des phases d'injection d'air et d'aspiration sont alternées afin de positionner l'élément de séparation, permettant ainsi l'insertion d'une buse d'approvisionnement dans chaque compartiment du récipient.

Patent CA-2268081-A1 (CA)
Inventor: BENNETT SCOTT P
IPC: C02F1/40
Filed: 1997-08-20
Abstract: We have found that foam generated from an aqueous medium can have a thermal insulating effect. The creation of a substantial volume of foam on the surface of an aqueous medium can reduce the apparent thermal IR emission substantially when compared to that of the aqueous medium free of foam. This difference in infrared emission can be used to control the addition of a defoaming agent to control foam in the aqueous medium. In the foam control method of the invention, an infrared detector is used to measure the infrared emission of an aqueous medium free of foam and during operations such a measurement is compared to the infrared emission of the aqueous medium under foaming conditions. As foam develops on the surface of the aqueous medium, the apparent thermal infrared emission from the foam is less than that of the aqueous medium free of foam. As the thermal IR emissions drop as foam develops, the difference between the apparent temperature of the foam and the aqueous medium, as measured as infrared thermal emissions, drops. Such a drop in temperature can be used to trigger the addition of a defoaming agent which can substantially reduce foam volume. As the foam volume is reduced, the thermal infrared emission of the aqueous medium returns to a value near the thermal inverting emission of the aqueous medium without foam. At this point, the addition of a defoaming composition is substantially reduced or stopped. During the control method, a predetermined limit is established at which the defoaming composition is introduced into the aqueous medium. As long as the thermal infrared emission of the foamed aqueous medium is different than the thermal infrared emission of the aqueous medium without foam, the defoaming agent is continually added to the aqueous medium. Further, the method permits the amount of defoaming agent added to the aqueous medium to be in proportion to the difference in infrared emission above the preset predetermined limit.

Title: Method and device for producing a hook-and-pile type closure part from thermoplastic plastics
Inventor: HAMMER PAVEL
IPC: A44B18/00
Filed: 1997-10-01
Abstract: The invention relates to a process and a device for manufacture of an adhesive fastening element with interlocking means integrated with a backing. The interlocking means are produced by introducing a thermoplastic into the gap between a pressure roller and a shaping roller. This shaping roller has a screen with openings which are produced by etching or by means of a laser so that the finished interlocking means result exclusively from the circumstance that the thermoplastic hardens at least in part in the openings in the screen.      This makes it possible to prepare the shaping roller at very low cost. In addition, a previously customary second process step in formation of the interlocking means is eliminated.

Abstract: The following is an abstract of my ~cup caddy.~ The shape is constructed specifically to accommodate take-out beverage cups, however will also hold beverage cans. It is built from a plastic mold, much like the shape of a coffee mug, only the body is open, not enclosed. It has a handle that functions on the same principle as a coffee mug, again with open encasement.  The caddy is plastic, reusable and durable. It was specifically designed to accommodate the mobility of hot beverages such as tea and coffee. It is well balanced so that one can easily pick up the hot beverage without worrying about it toppling over, thereby maintaining the same operational principles as a coffee mug. There are similar inventions on the market but they are all designed to house cups for mobility in a vehicle, rather than pedestrian mobility. According to my search, the only other similar product would be something put out by Tim Horton's. The designs are similar in size but not in structure. My invention houses all take out cup sizes, not limited to one size, nor to one retail distributor of beverages.

Abstract: A method and system for minimizing database overhead associated with AIN services includes a cascaded database structure having at least two databases.  The first database is a seed database containing basic information about the subscriber and his available services. The second database is a real-time database containing additional information that will be used by the appropriate service application. When the subscriber initially requests the service, the service management system creates an entry in the seed database for the subscriber. The entry contains an identifier for the subscriber and an identifier for the service. Until the subscriber actually uses the service, the seed database remains the only entry for the subscriber. When the subscriber actually uses the service, the service application reads the seed database to determine the privileges for the subscriber and creates a larger entry in the real-lame database. The service application may not write to the seed database. When the subscriber cancels the service, both the seed database entry and the real-time database entry are removed.

Title: Footwear customization system and process
Inventor: SWANSON STEPHEN C
IPC: A43D3/00
Filed: 1999-09-14
Abstract: A footwear customization system that includes a rearfoot and forefoot goniometer for measuring rearfoot and forefoot alignment of a foot to provide rearfoot and forefoot alignment data. A customizable piece of footwear having a moldable, settable midsole is mounted on a shoe press, and the shoe press applies pressure to the midsole based on the rearfoot and forefoot alignment data in order to form a contour in the midsole. The contour provides alignment corrections based on the rearfoot and forefoot alignment data. A computer running a footwear customization program can be interfaced to the rearfoot and forefoot goniometer and the shoe press to receive the rearfoot and forefoot alignment data from the rearfoot and forefoot goniometer and provide it to the shoe press. An injection apparatus can be used to set the midsole of the piece of footwear so that the midsole retains the contour after the piece of footwear has been removed from the shoe press. Preferably, the rearfoot and forefoot alignment of the foot is measured while the foot is in a non-weight bearing position known as sub-talar neutral.

Inventor: FITZPATRICK P JOHN
IPC: B63B25/14
Filed: 1999-09-22
Abstract: A marine gas storage and transport system formed of small diameter steel pipe, which is stacked horizontally in a hexagonal pattern. The system is suitable for use on top of a barge or inside the holds of a ship. The horizontal hexagonal stacking and the use of small diameter pipe permit large stacking heights to be reached without over- stressing the pipes at the bottom of the stack. The pipes are laid down in long straight lengths and are manifolded in groups of two (2) and seven (7) at their ends by a unique system that space-wise still permits the hexagonal stacking arrangement and also allows for about 33% (thirty three percent) of the system to be continuously inspected by a pig. Each group of seven can be connected to another group of seven and so also can the groups of two. Thus very large volume storage units can be constructed cheaply and efficiently. In addition when the pipes are stored within the holds of an ocean going ship a transverse watertight bulkhead is created approximately every 20 to 50 meters by infilling the spaces between the pipes with a watertight material. Since the spaces are small the force from the water head is low and the required longitudinal water-tightness can be provided by a number of materials ranging from silicone to epoxy products. This is a unique component of the invention as it precludes the expensive necessity of providing multiple penetrations through a standard watertight bulkhead.

Filed: 1999-10-21
Abstract: A low cost mixed analog digital application specific integrated circuit (ASIC) includes a standard central processing unit (CPU) programmed to execute a correlation function for arc detection. Use of a standard CPU is possible because need for digital fourier analysis is eliminated by the ASIC architecture. The ASIC includes a power supply configured to be coupled to an AC power line for supplying power to the ASIC components, and further includes a current sensor coupled to a current-carrying conductor for generating a signal representative of current in the conductor. A first analog-to-digital converter (ADC), coupled in series with the current sensor, has its output coupled to a central processing unit (CPU). The CPU supplies a digital-to-analog converter (DAC) with a digital signal representative of a portion of the sensed current. The DAC supplies this signal, in analog form, to a summer, which also receives an output signal from the current sensor. The summed analog output signal of the summer is converted to digital form by a second ADC and is supplied to the CPU. The CPU output is coupled to a trigger, e.g., a trigger of a circuit breaker.
