20090205510 | Rotary Cooker For Use With Chamfered, Stackable Cans - A rotary cooker and/or sterilizer is provided with a novel rail design to facilitate processing of chamfered, stackable cans and which prevents damage to the protective coating of chamfered, stackable cans which occurs in prior art rotary cookers. A split rail is provided having an inclined track for carrying and guiding one end of chamfered, stackable cans and a flat track for carrying and guiding the other ends of the cans so that the side wall of each can does not contact the rail and is not subjected to the abrasion of the side wall of the can otherwise caused by prior art flat rails used to carry and guide both ends of the cans. The rail design includes flanges for limiting side-to-side motion of the cans as well as rail segments which are placed in the rotary cooker wherein each rail segment supports and guides the top ends of cans in one row of cans and the bottom ends of cans moving in an adjacent row of cans. | 08-20-2009 |

20090048567 | PATCH - The invention provides a patch device adapted for use in the transdermal administration to a patient of a composition including one or more pharmaceutically, cosmetically, pesticidally, prophylactically, and nutritionally active substance, the patch consisting of a layered construct adapted to be adhered to the skin of a patient and defining a cavity for receiving one or more disruptable containers of the composition or components of the composition to be administered between a proximal layer and a distal layer thereof, which proximal layer is adapted in use to be located in intimate contact with the skin of the patient and which distal layer is in use disposed on the outer side thereof, wherein the proximal layer is partially permeable to that composition, so that in use the integrity of the one or more containers may be disrupted thereby causing the composition to be disposed in the cavity and permeate from there through the proximal layer to be absorbed through the skin into the body of the patient. The invention further provides a method of applying an irritant to the skin of a user. | 02-19-2009 |

20140302133 | CAPSULE WITH INTERNAL DIAPHRAGM - A capsule of, for instance, hard gelatin for holding a substance such as medicine, food supplements or similar materials includes a capsule body having a closed and an opposed open end with a predetermined length defined between the ends. A diaphragm having a closed end and an opposed open end and a predetermined length there between seals off the body and provides a first compartment to hold a first medicine, food supplement, etc. A cap is applied to the body as is conventional in capsules. The space between the inner portion of the cap and the diaphragm defines a second compartment for holding a second medicine, food supplement, etc. The contents of each compartment may be wet or dry (e.g., powder or liquid.) This two-compartment capsule has particular relationships between the length along an axis of the capsule of the diaphragm to that of the body, and particular dimensional parameters relating to the sidewall contact seal between the outer portion of the diaphragm and the inner wall of the body, to provide adequate capsule sealing and stability during and after manufacture. | 10-09-2014 |

20090200248 | Belt Filter Apparatus - The invention concerns a belt filter apparatus comprising a first belt filter section on which a mixture of fine material and a liquid can be placed hydraulically to create partially dry fine material and a second belt filter section on which the partially dry fine material can be placed in order to undergo a second drying cycle. The belt filter apparatus also includes means for mechanically placing the partially dry fine material from the first belt filter section onto the second belt filter section as well as a liquid collection arrangement for providing fluid communication between the first and second belt filter sections and a vacuum. In use the vacuum dries the fine material by drawing liquid through the permeable fabric of the first and second belt filter sections and into the liquid collection arrangement. The belt filter apparatus includes an agitator formation for increasing the permeability of the fine material to enhance the ability of the liquid to be released from the fine material and be collected by the liquid collection arrangement. | 08-13-2009 |
