Granted: 2009-01-06
Abstract: A drive connector for elastomerically coupling a drive shaft to a driven shaft. An elastomeric coupling (42) includes openings (74, 80) on opposite ends that are . generally "D"-shaped forming an interference fit with correspondingly shaped ends of the drive shaft and the driven shaft. A web (98) extends transversely within the interior of the elastomeric coupling, limiting the distance that the drive shaft and driven shaft are inserted within the openings of the coupling. The coupling includes a rib (72) that runs longitudinally along its outer length. A sleeve (86) having a groove (90) corresponding in size and shape to the rib is slipped over the coupling and is connected to the driven shaft. The sleeve includes a rigid interior element that is overmolded with an elastomeric material. A cam bearing (48) is fitted over a cam surface (96) on the sleeve (86) and provides a force in one direction, urging a plunger (58) to displace an elastomeric membrane (20) in a pumping cassette (10), forcing medicinal fluid to flow through the pumping cassette. The elastomeric membrane provides the restoring force to the plunger, so that a loop formed on the upper portion of the plunger and disposed around the cam bearing does not receive any force from the cam bearing to move the plunger away from the pump cassette. The elastomeric coupling and sleeve form a relatively compact assembly for coupling the drive shaft to the driven shaft and accommodate minor misalignment between the center lines of the drive shaft and the driven shaft.

Title: Process for introduction of additives and coadjuvants associated with a special thermal treatment for beverage packaging in plastic containers
Inventor: MORETTI ROBERTO HERMINIO
IPC: A23L2/84
Filed: 1998-11-19
Granted: 2006-03-14
Abstract: The process developed by the Applicant is characterized by the introduction into beverages (during one unique or more than one of the phases of the manufacture thereof) of a composition containing: (A) one or more enzymatic complexes comprising glucose-oxidase and catalase; (B) one or more preservative agents and optionally, (C) other food additives, (D) non conventional and mild special thermal treatment so as to allow the use of plastic containers in oxygen-sensitive products and/or requiring some type of thermal treatment like pasteurization, normally impossible to be executed in ordinary plastic containers.  The main function of the enzymatic complex (A) is to catalyse the reactions consuming the oxygen dissolved in the beverage and in the "headspace", without affecting the beverage's sensory characteristics. The enzymatic complex may comprise mainly two enzymes: glucose-oxidase and catalase. The glucose-oxidase catalyzes the reaction of the oxygen with glucose, forming the gluconic acid and the hydrogen peroxide that is later consumed by catalase, forming water and half of the original oxygen. These two are chain reactions which occur until the total consumption of the oxygen. During the shelf-life, the oxygen which permeates through the plastic packaging walls is also consumed through the same process; in case the oxygen is already in the container soon after the packaging, it shall also be consumed in the same manner, giving an extra protection to the product.   The preservatives (B) preserve the beverage microbiologically. The following may be used as preservatives: alkyl p-hydroxibenzoic acid or esters derived thereof, as for example: methyl p-hydroxibenzoic acid ester, ethyl p-hydroxibenzoic acid ester, propyl p-hydroxibenzoic acid ester, butyl p-hydroxibenzoic acid ester, heptyl p-hydroxibenzoic acid ester and octyl p-hydroxibenzoic acid ester. All of them are more active against yeasts and bacteria than benzoic acid, and lower dosages may be used. Jointly, such preservatives have a total and synergistic action, preventing the multiplication of microorganisms. Other food additives (C) may also, optionally, be added, like the antioxidants, eritorbic acid and salts thereof and/or ascorbic acid and salts and/or SO2 thereof and also stabilizers known by brewers, as for example, propylene glycol alginate.  The function of (D) is to empower the (B) activity, in order to guarantee the product's micro-biological stability.     Due to the characteristics of the beverage in which the process proposed has been added, any type of packaging can be used: tin, glass, card or plastic materials; we can mention, for example, packaging type PET, PEN, PVC, PP, PE, PC, PET/PEN blends, one or more polymer multilayers, etc.

IPC: B03B11/00
Filed: 1999-08-25
Granted: 2005-07-05
Abstract: The invention relates to a device and a method for chemically and physically separating solid materials from a suspension using flotation. A  rotationally symmetrical flocculation/flow reactor (20) is provided with outlets in the lower part thereof and is arranged in a separating tank (12). At least one suspension inlet (24) extends eccentrically into said reactor. The supplied suspension is guided into the upper area of the flocculation reactor (20) via the suspension inlet (24). A circular flow is thus created which drains off from the flocculation reactor (20) downwards in a tangential and radial manner over the outer circumference into circularly arranged distribution cells (44) which reinforce the tangential component of the suspension flow when said flow is delivered into the separating tank (12). In prior art, the flow of the mixture consisting of the suspension and air-sacs extends radially outwards. One advantage of the invention is that said flow of the mixture has to travel a longer way to the outlets in the area of the wall of the tank due to the tangential flow component. The solid matter can be separated more effectively by virtue of the longer travel path or the longer presence in the separating tank.

Abstract: A method of brewing a fluid extract using a filter pouch (10) containing flavor extractable particles. One step is supporting a fully compliant, fluid-permeable filter pouch partially filled with flavor extractable particles (14) such that the pouch is inclined at an angle to horizontal ranging from about 30 .degree.to about 90 .degree.so that the particles accumulate at a bottom end of the filter pouch. Another step is directing brew water to near an upper end of the filter pouch above the particles. The brew water enters the filter pouch without the need for an opening in the pouch, and drops to infiltrate the particles. The particles are partially fluidized by and suspended in the brew water and they rise with the brew water into an empty portion of the filter pouch without a need for opposing sides of the filter pouch to separate to generate internal space. A further step includes brewing a fluid extract from the particles in the filter pouch and dischargi ng the fluid extract from the filter pouch. The filter pouch has sufficient exit area that a fluid extract discharge rate matches a rate of brew water entry into the filter pouch when a fluid head is produced inside the filter pouch which is at least as great as a vertical depth of particles in the filter pouch.
