Title: Improvements in or relating to the removal of oxygen from water and solutions
IPC: B01J41/04
Filed: 1955-03-24
Abstract: A method of treating liquids to remove dissolved oxygen or peroxide therefrom comprises bringing the liquid into contact with a mass consisting of an ion-exchange resin having formed therein an insoluble metal oxide or hydroxide capable of reacting with the oxygen or peroxide in the liquid.  In given examples a cationic exchange resin in the sodium or hydrogen form is first treated with an aqueous solution of a metal salt, containing ferrous, manganous, cerous or cobaltous ions followed by an aqueous solution of an alkali metal such as caustic soda, caustic potash, byrata or lime water. When the resin has lost its capacity for removing the oxygen or peroxide it may be regenerated by an acid treatment followed by an aqueous solution of a metal salt and then with an alkaline solution. Anionic exchange resins of the hydroxyl form are treated with aqueous solution of a metal salt to form the metal oxides or hydroxides.  The resin may be regenerated by treatment with an acid, an alkali and a solution of metal salt in that order.  A cyclic method of treating liquids is described using two columns in series, one containing a cationic exchange and the other a similar amount of anionic exchange resin. In this method the cationic resin is treated to be capable of removing the oxygen or peroxide and then the anionic exchange resin is treated.  Further treatment returns the resins to the form at the beginning of the cycle.

Title: Improvements in or relating to record-card-controlled tabulating machines
Filed: 1923-04-09
Abstract: 197,657. British Tabulating Machine Co., Ltd., (Assignees of Hubbard, L. E.). May 10, 1922, [Convention date]. Statistical machines are provided with a device which will permit the machine to pause at the end of a card group before re-starting automatically on the next group, in order to permit a reading to be taken, the length of the pause being adjustable. The invention is shown applied to a machine of the Hollerith type, the machine being started by closing the switch 26 and depressing the key 27, thus completing a circuit through line 28, key 27, relay 29, motor 21, stop key 30 and the other side of the line. Coincidently a parallel circuit is closed through line 60 and a relay 61, energization of which opens the re-setting circuit of the machine; energization of the relay 29 allows release of the key 27 by providing an alternative path to the motor 21 through cam contacts 32, line 31, and armature of relay 29. The machine being now in operation the counter magnets 44 and clutches 48 are actuated as in Specification 131,277. While the card lever contacts 25 are closed by passing cards the relays 36, 37 are energized and the armature of the relay 37 establishes another holding circuit for the motor 21 through a line 38 and armature of relay 29, which circuit maintains the motor in operation when the contacts 32 break once per card cycle. Attraction of the armature of relay 36 partially completes the card circuits. After the last card has passed or when a stop card passes, the contacts 25 open and break one motor-holding circuit through the line 38, and when contacts 32 next open the other motor-holding circuit through line 31 is broken and de-energizes the relay 29. This stops the motor 21 and de-energizes the relay 61 which releases its armature and allows the contacts 62, 67 to close to complete the re-setting circuit. There is, however, a pause to enable the operator to take a reading between the de-energizing of the relay 61 and the closing of the contacts 62, 67, due to a dashpot 65, the armature 62 of the relay being connected by a link 63, Fig. 3, to a piston 64 which may move rapidly upwards by reason of a check-valve 66 but upon de-energization of the relay 61 the piston descends slowly by gravity, there being a slight leakage in the valve 66 to allow this pause, the length of which is adjustable by means of the screw 68. Near the end of the re-setting operation, the re-setting motor 73 rotates a cam to close the contacts 79, completing a re-starting circuit to the relay 29. Specification 131,277 is referred to.
