Abstract: 1410495 Aerating and defoaming liquids R A DEWALL 8 Sept 1972 [8 Sept 1971] 40192/ 72 Headings B1C and B1M [Also in Division A5] A bubble blood oxygenator comprising a mixing chamber 27 and means for supplying venous blood and respiratory gas thereto, includes an apertured assembly 46 for passing the gas into the mixing chamber and control means 53 for varying the area of the apertures which is effective to pass gas into the mixing chamber thereby to adjust the size of the bubbles formed in the mixing chamber. The gas dispersion assembly may comprise an inner tube 46 having several longitudinally arranged rows of apertures 49-51, the apertures in each row being of the same size as one another but being of a size different from the apertures of the other rows. The inner tube is rotatable within an outer tube 53 having a longitudinal slot 55 to selectively expose only one of the rows to the mixing chamber 27. The inner tube may be blocked by exposing an a pertureless portion 57 through the slot 55, a vent 60 in the outer tube then being aligned with a vent in the inner tube to permit the escape of gas outside the oxygenator. The oxygenator housing is generally cubical and the mixing chamber 27 has a movable wall 70 for varying its volume. Blood passes from the mixing chamber 27 to a debubbling chamber 81 and thence along a ridged ramp 82 to a reservoir ramp 115 delivering one side of a reservoir 117 from which it reaches the outlet (28). In the debubbling chamber the blood passes through a defoaming bag 87 comprising a rigid mesh framework surrounded by layers of polypropylene net or polyurethane grid material coated with a defoaming agent, and a filter 129. The temperature of the blood is controlled by either a plate 126 which is electrically activated or includes a passage for water or by the reservoir ramp (155) Figures 8 and 9 (not shown), which has a corrugated surface and channels for water. Alternatively the oxygenator may be mounted on a temperature-controlling water channel member (206) Figure 10 (not shown) which engages the underside of the reservoir ramp (208). Medicament may be injected into the blood through a vent 125 and a suction device for collecting blood from the patients wound may be connected to the mixing chamber at a fitting 25. A float (122), Figure 4 (not shown) in the reservoir prevents air passing through the outlet when the oxygenator is empty of blood.

Filed: 1958-12-15
Abstract: 887,112. Superconductor circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 15, 1958 [Dec. 17, 1957], No. 40333/58. Class 40 (9). [Also in Group XIX] Two bi-stable cryotron pairs are combined to form a unit in which a change in the condition of one pair A, C is followed after a delay, by a change in the condition of the other pair B, D, which resets the first pair and is itself reset after a further delay. The arrangement provides an output pulse of substantially constant length in response to an input pulse of shorter length. A modified unit runs freely like a multivibrator. Units may be connected in chains to form ring- circuits or shift registers. Only one cryotron of a pair A, C (or B, D) conducts and the pair has two conditions in which A and C (or B and D) conduct respectively. The two pairs A, C and B, D are supplied with current from sources 12, I1. Input pulses are applied to normallyconducting cryotron A on winding 26. The currents IA to ID in the controlled elements of the cryotrons A to D are shown in Fig. lb. The length of the break pulse in IA is substantially constant for input pulses within the limits shown. The circuits supplied from source I1 have longer time constants than the circuits supplied by 12. The circuits are arranged so that, to make cryotron C resistive, a 90% switch of current I1 to winding 14 is necessary. A 50 % switch of current 12 to winding 20 is sufficient. Free-running circuit, Fig. 2a.-Cryotron D is coupled by a winding 30 to cryotron A to feed back pulses to the input. Ring circuit, Fig. 3a (not shown).-Cryotrons B, D of Fig. 1a are connected to the input of a succeeding stage, a number of stages being connected in a ring. The ring is free running. Shift register, Fig. 4a.-A number of circuits like that shown in Fig. 2a are linked together as shown and the current sources I1 are replaced by connections 44 to a source of shift pulses. If cryotrons An, Dn in stage n are conductive, Dn conducts a shift pulse to set Cn +1 to the same resistive state as Cn. Information is written into the register by means of windings 26, 26<SP>1</SP> &c., 42, 42<SP>1</SP> &c. In this circuit cryotrons A, C have larger time constants than B, D. The cryotrons may be thin film cryotrons. Specification 862,178 is referred to.

Title: Improvements in or relating to methods of producing carbides in granular form
Inventor: CARLEY-MACAULY KENNETH WALLACE
IPC: G21C3/62
Filed: 1960-11-29
Abstract: Carbides of the nuclear fuel substances uranium, thorium and plutonium are produced in granular form by preparing a finely-divided mixture of the relevant oxide with at least the stoichiometric amount of carbon necessary to form the carbide, forming the mixture into granules of the desired size and heating them to convert the oxide to the carbide.  The granules may be formed by compacting the mixtures, preferably in the presence of an organic binder such as ethyl-cellulose or furfuryl alcohol, breaking down the compact and selecting granules of the desired size, e.g. by sieving, and re-compacting the discarded granules. Suitable particle sizes are 1-5m  for the mixture of oxide and carbon and 50-100m  for the granules.  Suitable forms of carbon are carbon black and crushed graphite powder.  The conversion of uranium oxide may take place at atmospheric pressure in an inert atmosphere, e.g. argon, at 2000 DEG C. for 4 hours with a curing step at 800 DEG  C. if an organic binder has been used and thorium oxide may be converted at a temperature of at least 2000 DEG  C. in vacuo.  A tumbler furnace may be employed to prevent sintering.  If a diluted fuel is desired more than the stoichiometric quantity of carbon may be used.  The method is especially suitable for producing intimately mixed carbides of uranium and thorium. The carbide granules may be coated with carbon pyrolytically at 900 DEG  C. in a tumbler furnace in the presence of propane. An example of preparing UC2 is given. Specification 878,927 is referred to.
