The invention provides an article for oxygen absorption comprising a container containing a water-soluble ion source, an water activated oxygen scavenger, and a rupturable canister of hydrated polymer. The invention provides in another embodiment a method for providing timed or controlled oxygen absorption comprising providing an article for oxygen absorption comprising a container containing a water-soluble ion source, an water activated oxygen scavenger, and a rupturable canister of hydrated polymer, rupturing the canister, whereby the hydrated polymer and water-soluble ion source come in contact and release water, and the water as it is released activates the oxygen scavenger.
摘要:
An oxygen-absorbing composition including iron and a soluble tartrate. A method of absorbing oxygen from a closed environment including the steps of providing an oxygen-absorbing composition containing iron and a tartrate, injecting water into the composition, and placing the composition into the closed environment. An oxygen-absorbing packet containing iron and tartrate. All of the foregoing-mentioned compositions preferably include an electrolyte. The tartrates may be selected from the group which may include sodium acid tartrate, potassium acid tartrate, potassium sodium tartrate tetrahydrate and sodium tartrate dihydrate, but are not limited thereto.

An integrated U-tube and adsorbent unit (10) including a U-tube (19) having first and second legs (20, 22) and a return bend (21), a space (37) between the first and second legs (20, 22) and the return bend (21), adsorbent (39) in the space (37), opposite sides (24, 24') on the first and second legs (20, 22) and the return bend (21), permeable covers (40, 40') bonded to the first and second opposite sides (24, 24') to contain the adsorbent (39) within the space (37), a hole (26) in the return bend (21), a frame (41) connected to the U-bend (21) and defining a space in communication with the hole (26), and filter material (47) on the frame (41). An integrated U-tube and adsorbent unit (94) including a plastic U-tube (82) and a self-contained adsorbent unit (70) having a plastic cover (71) bonded to the U-tube (82) with the body of the self-contained adsorbent unit positioned between the legs (83, 84) of the U-tube.
摘要:
An adsorbent unit assembly (10; 10a; 10b; 10c; 10d; 10e) including a holder (11; 55; 65; 75; 85; 100; 109), an elongated member (12; 57; 65; 75; 87; 100; 110) on the holder, an enlarged portion (14; 61; 69; 77; 101; 112) at the end of the elongated member, a cylindrical adsorbent unit (17) having an opening (23) therein for receiving the elongated member, and a grid (27; 27'; 80; 27') mounted on the elongated member on the opposite side of the adsorbent unit from the enlarged portion. The foregoing adsorbent unit assembly (10; 10a; 10b; 10c; 10d; 10e) is mounted within the housing (39) of a receiver dryer (37) by compressing one or more adsorbent units (17) on the elongated member between the grid and the enlarged portion so as to cause the outer sides of the adsorbent units to bear against the inside surface of the housing while the grid also provides an interference fit with the housing.
