Inventor: TIMM GERALD L
IPC: F28F5/02
Filed: 1991-05-06
Abstract: A low differential pressure rotary syphon for the purpose of removing condensate from the interior of a heated dryer drum under low differential pressure conditions. The reduction in the magnitude of differential pressure required to remove the condensate is accomplished through the direct introduction of steam into a central plenum area receiving condensate thereby reducing the mass density of the condensate mixture. The reduction in mass density and the steam introduced acting directly on the condensate within the central plenum area facilitates the removal of the condensate from the drying drum interior. <IMAGE>

Filed: 1998-08-12
Abstract: A method of setting a timer associated with a protocol supportinga data link in a digital mobile communication system in a connection section. At least one party (MSC/IWF, MS) to the connectionsection monitors if the need to change the timer value has arisen. Should such a need be detected, the timer value (S) is set to avalue deviating from the initial value. The need to change the timer value (S) is also determined during the connection, such asin handover, for example by measuring the propagation delay associated with the connection section. This may be implemented by either of the parties to the connection transmitting to the other party a frame (F) which is selected/formed such that the party receiving the frame sends an acknowledgement (Ack) to the transmitting party. The party which transmitted the frame measures the timefrom the moment of transmission of the frame (F) to the arrival of the acknowledgement (Ack) and deduces the propagation delay (D) therefrom.

Filed: 1953-01-15
Abstract: 718,952. Radar. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 15, 1953 [Jan. 18, 1952], No. 1237/53. Class 40 (7) A radar receiver with a plan position display provided on a long afterglow screen includes electronic calibration mark generators for providing range and/or azimuth calibration indications on the screen and switch means for suppressing the echo signals and producing said calibration marks relative to a reference centre displaced from the normal image centre. In a preferred embodiment the cathode-ray tube 1 on which the disp'ay is presented is provided with a delta connected stationary coil system 2 normally energized 'through mags ip generator 3 the rotor 4 of which is moved in synchronism with the aerial scanning and fed by time base generator 5. An eccentric voltage generator 7 is interposed between the generator 3 and the coil system 2 to enable the centre of the display to be shifted to any convenient point. The echo signals are fed from the receiver 8 to intensity modulate the tube in usual manner and are controlled by varying the receiver valve screened-grid voltages by means of potentiometer 10 connected to voltage source 9. A calibration mark generator similarly provides range indications on the tube at a level determined by potentiometer 12. The mean brightness of the tube is controlled by potentiometer 14. The system thus far described gives a plan position indication with range circles the image centre of the display being off-set if desired from the tube centre. Operation of relay 62 controlling switches 15, 17, 33 and 34 blanks out the echo signal indicators, returns the image centre at the centre of the screen and enables the brilliance of the calibration indications to be increased. For the production of a bearing calibration -line on the tube screen relay 61 is operated to change over switches 20 and 21 to substitute manually adjustable magslip generator 18 for generator 3. An eccentric voltage generator 22 is provided to shift the origin of the bearings line if desired. Relays 61 and 62 may be coupled together by switch 65 and jointly contro'led by a foot control 63, alternatively the projection of the plan position image and of the calibration image may be changed over' automatically so as to maintain both indications visible on the long persistence screen. The use of the apparatus to indicate the actual and desired course of a moving craft is described with reference to Figs. 3 and 4 (not shown) and a suitable eccentric voltage generator is described with reference to Fig. 2 (not shown). To check the linearity of the radar, range circles may be drawn about two centres at n units distance apart and a visual inspection made as to whether the circles touch, Fig. 5 (not shown). It is pointed out that triangulation measurements may be performed by means of the display.

Abstract: The invention comprises 21-alkoxyoxalyl-11-ketoprogesterone alkali metal enolates of the general formula <FORM:0733448/IV (b)/1> wherein M represents an alkali metal and R represents an alkyl radical, and a process for the preparation thereof by mixing 11-ketoprogesterone with an alkyl diester of oxalic acid in the presence of a catalyst consisting of an alkali metal or an alkali metal base, and maintaining the temperature of the reaction mixture between about 0 DEG  C. and the boiling point of the reaction mixture.  The preferred compounds are those in which the alkyl radical of the alkoxy group contains from 1 to 8 carbon atoms inclusive, and those in which M represents sodium or potassium. The alkyl radicals of the diester of oxalic acid may each contain from 1 to 8 carbon atoms.  The catalyst may be an alkali metal alkoxide, e.g. containing from 1 to 8 carbon atoms in the alkyl radical, a solution of an alkali metal in an alkanol the alkyl radical of which contains 1 to 8 carbon atoms, an alkali-metal hydride, sodium amide or triphenylmethyl sodium.  About one molar equivalent of the catalyst may be used.  The reaction may be carried out in an alkanol corresponding to the ester of the oxalic acid, or in an inert solvent such as benzene or ether.  In the examples the following compounds are prepared: the sodium and potassium enolates of 21-methoxyoxalyl-and 21 - ethoxyoxalyl - 11 - keto - progesterone and the sodium enolate of 21-propoxyoxalyl-11-keto-progesterone, the catalyst used being sodium methoxide, potassium in tertiary butyl alcohol, sodium in methanol and in propanol, and sodium amide.  Additional compounds referred to are the sodium and potassium enolates of 21 - butoxy -, 21 - amyloxy -, 21 - hexyloxy-, 21 - heptyloxy - and 21 - octyloxy - oxalyl - 11-keto-progesterones.  21 - Acetoxy - 11 - ketoprogesterone is obtained by reacting iodine in methanol with an enolate of the above general formula and then adding sodium methoxide in methanol to form 21-iodo-11-ketoprogesterone which is then reacted with acetic acid in the presence of potassium bicarbonate to form the 21-acetoxy radical.

Title: Improvements relating to the decomposition of nickel carbonyl
IPC: C22B23/06
Filed: 1947-01-15
Abstract: A process for the decomposition of nickel carbonyl in which nickel pellets are pre-heated and caused to flow in counter-current to gas-containing nickel carbonyl, the initial composition of the carbonyl, the rate of flow of the gas and the initial temperature of the pellets being correlated to eliminate carbon deposition wholly or substantially wholly.  The heat for decomposition of the carbonyl may be supplied wholly by the pre-heated pellets.  The process may be carried out in a vertical decomposer in which the nickel pellets move downwards and in which the gas inlet may be situated at the bottom of the chamber and a gas outlet at the top, means being provided above the gas outlet for pre-heating the pellets.  Some of the gas removed from the decomposer may be led to a point in the path of the pellets beyond that at which the carbonyl containing gas first comes into contact with them, so as to set up a back pressure in that path.
