Patent SE-8902709-D0 (SE)
IPC: A61B18/00
Filed: 1989-08-10
Abstract: A device (1) for use in the discharge of fumes (20) from an operating site (16), e.g. in laser surgery (17, 19), comprises a chamber (3) which is defined by a body (2) and has a bottom opening (4) to be placed over the operating site (16) for conducting fumes (20) emitted therefrom into the chamber (3), and a working opening (5) substantially opposite to the bottom opening (4) for providing access to the operating site (16) through the chamber (3) and the bottom opening (4). A first end (8) of an exhaust duct (7) opens in the vicinity of the chamber (3), and a second end (9) of the exhaust duct is adapted to be connected to a negative pressure for sucking off fumes (20) conducted into the chamber (3). One or more air passages (10-13) extending from the outside of the body (2) and separate from the bottom and working openings (4, 5). These separate air passages (10-13), as well as the first end (8) of the exhaust duct (7), open in the chamber (3) between the bottom opening (4) and the working opening (5) at two opposite sides of the chamber (3). Thus, a lid of laminar air flows (10', 11', 12', 13') is formed in the chamber (3), thus preventing leakage of fumes through the working opening (5).

Abstract: The air flow produced by the excess inner air pressure in the roller creates a fairly constant friction coefficient between the cylinder (5) and the slide bearing (2) during operation. Excess pressure in the roller is produced by connecting it to a compressed air system through a hole in an axle screw (3) hollow shaft (4) and through a hole in the cylinder. The occurrence of a small air loss through the plastics-sealed ball bearing (6) is of little importance.

Patent SE-9301641-D0 (SE)
IPC: A23N1/00
Filed: 1993-05-13
Abstract: The present invention is for a worm press for extraction of plant and fruit juices, such as orange juice and grape juice. It is important that the pressing takes place at high pressure but that only small amounts of heat are developped. A worm press according to the invention has a housing with an inner circular cylindrical volume, wherein there is a worm screw. The housing has openings as required for the supply of plant material and feed in out of the remains after the extraction. The worm is correspondingly designed with a feed in section and an extraction section. Essential for the invention is the design of the worm threads in the extraction section and the adaption of the worm to the housing in this part thereof. The diameter of the central core (5) of the worm is essentially smaller in the feed in section than in the extraction section. Furthermore, the core diameter and the pitch of thread in the feed in section are preferably constant and the worm here works like a simple feed screw. In the extraction section the diameter of the core as well as the pitch of the worm thread (4) vary. Seen from the feed in section the diameter of the core increases and the pitch of the thread decreases. Furthermore, the core is so designed that its outer surface between the threads always is parallel with the axis of the worm and thus also with the inner cylindrical surface of the housing.

Title: Process and apparatus for removal of oxygen from seawater
Filed: 2011-11-14
Abstract: A process and apparatus is provided for reduction of dissolved oxygen content in seawater from about 8 ppm in the feed seawater to about 10 ppb or less. Significant advantages are achieved by: use of a separator in horizontal alignment to provide high gas-liquid contacting area for separation and de-entrainment within the separator, thereby providing higher throughput; and heating seawater to at least 30° C. and up to 60° C., so as to enhance removal of oxygen from seawater; use of once-through fuel gas as stripping gas and its subsequent combustion for heating the seawater provides for high efficiency and reduction of fouling. The combination of these features allows the amount of residual oxygen in deoxygenated seawater to be reduced to below 10 ppb and as low as 2 ppb.
