Title: Fruit and vegetable bag dispensing system
Inventor: LEDGER GREG
IPC: A47F9/04
Filed: 1998-09-09
Abstract: A fruit and vegetable bag dispensing system is disclosed having a bag roll with a central passage and being formed from a continuous web of bags. Each bag has a top edge, a pair of opposed side edges and the bottom edge. Each bag is attached along the top edge and the bottom edge to the next adjacent bag, the attachment being along a line weakness.      Each bag also has a closed bottom edge and an open top. The line of weakness includes a centrally cut portion generally centrally disposed between the bags side edges. The system further includes a bag dispensing rack having a rear wall mounting portion and an opposed pair of outwardly projecting frame elements extending from opposite sides of the rear wall mounting portion. A bent member is attached between the frame elements, the bent member having upwardly extending free ends and a middle web guiding portion extending between the frame elements along the lower front edge. A roll supporting element is non-rotationally mounted on the free ends of the bent member, the roll supporting element being sized and shaped to fit into the central passageway of the roll. Also provided is a snag member which extends forwardly and upwardly adjacent to the web guiding portion of the rack. Thus, the leading edge of the bag web passes under the middle portion of the bent member and across the snag member and as the bag web is drawn out the snag member catches the centrally cut portion to retain the next to last bag on the rack while freeing the last bag from the continuous web.

Title: Gas turbine combined cycle
Inventor: SUGISHITA HIDEAKI
IPC: F01K9/00
Filed: 1999-02-25
Abstract: The invention provides a gas turbine combined cycle structured such that an intermediate cooling device for cooling a compression air discharged from a low pressure compressor, so as to reduce a load of a high pressure compressor, is provided. The gas turbine combined cycle in accordance with the invention is structured such as to branch water from a condenser to a steam generating device for generating steam. Exhaust gas discharged from a steam turbine is condensed to water. Compression air discharged from a law pressure compressor is cooled by being supplied to an intermediate cooling device, and is then supplied to a high pressure compressor. Steam which heats and operates the steam turbine is generated by the heat recovered by the cooling of the compression air in the intermediate cooling device. Accordingly, there can be obtained a gas turbine combined cycle having the advantage of the conventional intermediate cooling type gas turbine combined cycle, but exhibiting an improved combined efficiency.

Inventor: VAN BERESTEIJN EMMERENTIA CATH
IPC: A23L1/305
Filed: 1998-01-16
Abstract: La présente invention se rapporte à un procédé permettant une hydrolyse sélective de caséine/caséinate en présence d'au moins un autre constituant protéique, autre que la caséine ou le caséinate, ladite caséine ou le caséinate et l'autre constituant protéique étant amenés en contact avec un enzyme protéolytique dans des conditions favorisant l'hydrolyse de la caséine ou du caséinate. Ledit procédé se caractérise en ce que la caséine ou le caséinate et de préférence également l'autre constituant protéique se présentent sous forme sensiblement dissoute, et en ce que l'enzyme protéolytique est une protéinase spécifique de la caséine ou du caséinate, de sorte que la caséine ou le caséinate est hydrolysé alors que l'autre constituant protéique demeure sensiblement intact. Ce procédé peut servir, notamment à la préparation d'une caséine hydrolysée ou éventuellement à la préparation d'une composition à base de protéines du lait, notamment une préparation protéique à base de lactosérum de laquelle on a retiré la caséine ou le caséinate. Cette invention se rapporte en outre aux préparations ainsi obtenues, qui sont dotées de propriétés bénéfiques s'agissant d'éviter les réactions allergiques associées aux protéines du lait, et pour les sujets diabétiques.

Title: Induction assembly for high efficiency air filter
Inventor: WILLKE HERBERT L JR
IPC: B01D46/42
Filed: 1998-04-17
Abstract: An induction assembly (100) for a high efficiency air filter includes a primary intake plenum (102), a primary throat aperture (106), a secondary intake plenum (112), a momentum transfer section (114), a static regain section (116), and a discharge opening (122). The primary intake plenum (102) directs primary air at high pressure to the primary throat aperture (106), which constricts the flow of the primary air and consequently increases the primary air velocity. The primary throat aperture (106) directs the high velocity primary air into the momentum transfer section (114), thus creating a negative pressure region by the Bernoulli principle and drawing a substantially equal quantity of the secondary air into the momentum transfer section (114). After the primary and secondary gasses mix in the momentum transfer section (114), the gas mixture continues on into the static regain section (116). As the gas mixture passes through the static regain section (116), the velocity pressure of the gas mixture is converted into static pressure, which is sufficient to force the gas mixture through a resistance at the discharge opening (122) such as an output filter (126).
