Title: Improvements in and relating to vacuum electric tube devices
IPC: H01J21/20
Filed: 1928-12-08
Abstract: 328,960. Robinson, E. Y., and Associated Electrical Industries, Ltd. Dec. 8, 1928. Vacuum tubes. - To compensate for secondary emission from the grids of triode amplifying valves with oxidecoated cathodes, a diode has its cathode and anode respectively connected to or integral with, the cathode and grid of the triode, The active surface of the anode of the diode is uninfluenced by the anode of the triode and is sufficiently outside the latter to keep cool by radiation. The diode is inoperative so long as the grid of the triode does not become momentarily positive but if this occurs, due to the reception of a signal exceeding the grid bias of the triode, the diode conducts and augments the forward grid current of the triode circuit. Secondary grid emission tending to give the grid circuit a negative, resistance characteristic and thus to produce parastic high-frequency oscillations or distortion is thus swamped. In a large output stage with triodes in " push-pull " and with transformer couplings, the cathodes 11, 12 and grids 15, 16 of the triodes 2, 3, Fig. 1, are connected as shown to separate diodes 7, 8 inside or outside the triode envelopes. The diodes 7, 8 may be replaced by triodes. the filaments and grids of which form diodes of variable impedance and the anodes of which are connected to a low adjustable potential. Resistance-capacity or choke couplings may be used instead of transformers. In one constructional combination of diode and triode, the triode grid 20, Fig. 3, is connected at one end to a plate or close-mesh electrode 19 projecting beyond the anode 13 and surrounding the extended end of the filament. In another construction, channel-shaped plates 23, 24, Fig. 4, around which the grid 22 is wound and which enclose the outer limbs of a zig-zag filament 21 act similarly to the electrode 19, the anode comprising two plates. In a further modification, extensions of the filament and grid beyond the surrounding anode are. screened from the anode by an earthed screen. Specifications 211,551, 231,225 and 303,767 are referred to.

Title: Production of ketones
Inventor: GARDNER JAMES HAMILTON
IPC: C07C45/00
Filed: 1957-11-21
Abstract: A process for preparing "high molecular weight" ketones comprises reacting ethylene at temperatures below about 100 DEG C. with a quantity of acetaldehyde sufficient to form "high molecular weight" ketones containing on average at least one acetyl group, and with elemental oxygen in excess of 10% by weight of the acetaldehyde, the ethylene being introduced at a rate such as to maintain the ethylene partial pressure above about 500 p.s.i.  The products may also contain other oxygenated groups such as ester, carboxyl and ether groups.  The molecular weight is stated to be consistently above 175. An organic solvent may be used.  Preferred ethylene partial pressures are 500 to 5000 p.s.i. The oxygen is preferably fed continuously at a rate of at least one, e.g. 1-25, standard cubic foot per hour per cubic foot of reactor.  The process may be operated continuously or batchwise.ALSO:A process for preparing "high molecular weight" ketones comprises reacting ethylene at temperatures below about 100 DEG  C. with a quantity of acetaldehyde sufficient to form "high molecular weight" ketones containing an average at least one acetyl group, and with elemental oxygen in excess of 10% by weight of the acetaldehyde, the ethylene being introduced at a rate such as to maintain the ethylene partial pressure above about 500 p.s.i.

Abstract: 853,994. Extracorporeal treatment of blood. DERVEAUX, R., and ZACONTO, F. Dec. 4, 1956 [Dec. 6, 1955]. No. 36994/56. Class 81 (2). In apparatus, for rapidly varying the temperature of the body, in which blood is circulated in an extracorporeal circuit, the circuit comprises a blood take-off hose 3, a thermic exchanger 11 in which the blood is heated or cooled as required, a return hose 15 and at least one pump. For cooling the head, blood passes from the superior vena cava 2 of a patient through a hose 3 to a tank 4 arid is then directed through a heat exchanger 11 by a pump 6. After passing through an oxygenator 40, the blood is returned to the carotid artery of the patient by way of a hose 15. Tanks 25, 26 of brine maintained at about -40 ‹C. and 65 ‹C., respectively, are connected by valves 27, 28 with a mixer 31. The amounts of brine permitted to flow from each tank 25, 26 to the mixer 31 are chosen so that the resulting mixture has such a temperature, measured by a thermometer 37, that the blood in the heat exchanger 11 can attain the temperature desired. The brine mixture flows into the heat exchanger 11 which comprises brine tubes 24 surrounding capillary tubes 10 for the blood. The brine flows into a container 36 from the heat exchanger 11. Pressure gauges 18, 19, 20 measure the pressures of the blood on leaving and entering the body and the differential pressure across the heat exchanger 11, respectively. The temperature of the blood on entering and leaving the heat exchanger 11 is measured by thermometers 38, 39 which are so connected with the mixer 31 that the supply of brine to the heat exchanger 11 ceases when the blood reaches the temperature desired.
