Abstract: A regulator assembly is provided for use in a respirator system to supply a regulated flow of air to a respirator head piece. The respirator assembly comprises a housing (15) having an air inlet port (17) for connection to a source of air at comparatively high pressure, and an air outlet port (23) for connection to the respirator head piece. The housing (15) contains an air pressure-reduction stage (19) in communication with the inlet port (17), and a noise-reduction stage (21) between the pressure-reduction stage and the outlet port (23). The noise reduction stage (21) comprises two, spaced, muffler discs (41, 43) the first of which is positioned adjacent the air outlet (39) of the pressure-reduction stage (19). A deflector plate (47) deflects the airflow from the pressure-reduction stage (19) through the first muffler disc (41), and thereby diffuses the air flow before it reaches the second muffler disc (43).

Abstract: Disclosed is a vacuum container including a container body, a lid for closing the upper end of the container body, a depression defined on the lid, a boss formed on the lid and defined with an air hole, a rotary cover rotatably arranged in the depression and having an accommodating space, and a closure member having a through-hole and coupled to the rotary cover.      The vacuum container also includes an airtightening element having a hollow body part fitted around the boss and a lip part extending in a radial direction from the hollow body part. A vacuum maintaining member includes a semi-spherical body received in the closure member and having an airtightening flange part brought into contact with the lip part of the airtightening element. An exposure bar extends upward from the semi-spherical body such that a part of the exposure bar is exposed to the outside through the through-hole of the closure member. The exposure bar is moved upward and downward in accordance with a vacuum state of the inside of the container body. The vacuum container effectively and reliably maintains the inside of the vacuum container under a vacuum state. Also, a user is allowed to easily confirm the vacuum state of the container with the naked eye, and to check an initial vacuumization date of a food item or the remaining effective vacuumization periods, as occasion demands.

Abstract: A crude oil recovery system (10) includes a downhole pump (22) and an extension (60) that extends below the downhole pump (22). The extension (60) has an extension inlet (62) positioned below the lowest drawdown level (L2) achievable by the pump (22). All of the fluid pumped by the downhole pump (22) enters the extension (60) via the extension inlet (62), and by positioning the extension inlet (62) sufficiently below the lowest drawndown level (L2) achievable by the pump (22), pressurized gas (82) is prevented from entering the extension (60), the pump (22), or the pump column (40) above the pump (22). In this way, gas (82) is prevented from displacing oil (80) in the pump column (40), thereby maintaining excellent cooling for the polish rod (38), and gas (82) is confined to the borehole annulus (18), where it can readily be recovered or vented.

IPC: C07J1/00
Filed: 2004-09-22
Granted: 2013-11-05
Abstract: A method of identifying post-translationally modified proteins is disclosed. The method comprises mass analysing peptide ions and then subtracting from the determined mass of the peptide ion the known increase in mass due to one or more modifications of interest. The resulting value which represents the mass a peptide would have, had the protein from which it is derived hot been modified, is then used to search against a peptide databank. A short list of possible peptides is formed by selecting peptides which have both the right mass or mass to charge ratio (to within a user specified tolerance) and which also support at least one of the user selected modifications of interest. Each short listed peptide is then scored in turn against fragmentation data related to the experimentally observed peptide.
