Title: Method of raising the concentration of heavy water
IPC: C01B5/02
Filed: 1946-01-10
Abstract: 620,837. Electrolysis of water. NORSK HYDRO-ELEKTRISK KVAELSTOFAKTIESELSKAB. Jan. 10, 1946, No. 929. Convention date, Dec. 21, 1942. [Class 41] In the production of " heavy " water by the electrolysis of water in a group of cells with the use, as feed water in one group of cells, of water which has been given off as vapour in another group and condensed, the supply of water vapour is increased by the use of a gas brought into contact with the electrolyte, the gas being subsequently cooled to condense the vapour. In the arrangement shown in Fig. 1, hot electrolyte is pumped from electrolytic cells (not shown) through a pipe 2 to a distributing pan 3 in a vessel 1 and returns to the cells by a pipe 4. The vessel is connected to a cooler 5 by means of two pipes 6, 7. If the gas above the liquid in the vessel 1, as for example oxygen given off by the electrolysis, has a specific gravity higher than that of the water vapour, the gas will rise in the pipe 6 and return to the vessel 1 by way of pipe 7. The condensate is withdrawn through a pipe 8. If, however, hydrogen is the carrier gas the circulation will be up through pipe 7 and down through pipe 6. In a modification shown in Fig. 2, a gas not produced by the electrolysis, for example nitrogen, is supplied to the electrolyser 1 through a pipe 3. The gas is mixed with hydrogen obtained electrolytically and is passed through a pipe 4 to a cooler 2. After the gases have been cooled they are discharged through a pipe 5. The condensate is withdrawn through a pipe 6. The mixed gases are subsequently used to make ammonia.

Abstract: 1,215,447. Combustion air supply. ASSOCIATED BRITISH COMBUSTION Ltd. 8 Jan., 1968 [6 Jan., 1967], No. 943/67. Heading F4B. The windbox of a furnace is provided with air apertures leading into the furnace chamber, the diameter of which apertures increase with the height at which they are situated in the furnace, to compensate for pressure variations in both the furnace chamber and the windbox at differing heights so that, in use, equal quantities of air are supplied through each aperture. When the combustion air is supplied horizontally to the windbox the apertures may also increase in diameter in the direction of the air supply to the windbox. The variations in aperture diameter may be obtained by inserting sleeves of the requisite thickness into the preformed apertures.

Title: Method for reacting two components,compositions,coating compositions and uses thereof
Inventor: SCHINDLER FREDERICK JANES
IPC: C08L101/00
Filed: 1993-08-26
Abstract: Carbon Michael cure is effected by combining a tertiary amine component, an epoxide component, a component with Michael Reaction-active methylene groups, and a component with Michael Reaction-active alkene groups. The tertiary amine and epoxy components are combined during or shortly before combination of all components. Two-pack ambient cure coatings using this method have improved combinations of pot life, early cure, gloss, and ultimate cure. Improved resistance to water is achieved when the epoxide component and/or the tertiary amine component are pre-reacted with a Michael Reaction-active component during cure. Low cost and hazard, together with good cure and resistance properties are achieved when the Michael Reaction-active alkene groups are from a particular class of maleic/fumaric polyesters. When the methylene groups are acetoacetate moieties, low colour is achieved when the alkene groups are acryloxypropionate moieties, or when the alkene groups are acrylate moieties and the molar ratio of alkene moieties to acetoacetate moieties is greater than 1.5. Lower colour is achieved with fumarate and acrylate when the methylene groups are malonate rather than acetoacetate.

Title: Disk autochanger
Inventor: ENOMOTO KAZUHISA
IPC: G11B17/28
Filed: 1994-01-05
Abstract: PURPOSE:To facilitate size management and to adequately take out disks. CONSTITUTION:The top end part of a moving member 330 is provided with triangular projections 336 for closing the top end sides of disk housing grooves 304 of a tray 300 at every other pitch. This moving member 330 is moved by movement of a sliding member 320. As a result, these triangular projections 336 are shifted from each other by one pitch of the disk housing grooves 304 and the front ends of taking-out arms are guided between the triangular projections 336 in the case of taking the disks out of the tray 300. Then, the pitches at the peaks of the triangular projections 336 widen to about twice the disk pitch and, therefore, the insertion at the front ends of the taking out arms into the disk housing grooves 304 housing the disks 310 to be selected is surely executed. The restriction on the positional accuracy at the front ends of the taking out arms and pitch accuracy, etc., of the disk housing grooves 30 formed by partition plates 303 is consequently greatly relieved.

Title: Friction time and upset timing control method in friction pressure welding
Inventor: TERABAYASHI TAKAO
IPC: B23K20/12
Filed: 1979-01-08
Abstract: PURPOSE: To let the captioned controlling be readily and accurately effected by applying DC micro-voltage between the both welding works and operating timers by the current flowing when the both welding works contact thereby letting upset pressure be acted.  
     CONSTITUTION: When pipes 10, 17 contact, a circuit 90 closes and therefore a relay 42 acts. Then, a circuit 100 closes and therefore a timer 43 acts and after its set time has elapsed, the output side relay 44 operates and a clutch 46 goes off to cause a brake 47 to act, due to which the rotation of the pipe 10 stops. The operation of the relay 42 causes a circuit 102 to close to operate a timer 49. After the lapse of its set time, a relay 48 operates and therefore coils 50 and 51 change over, by which upset pressure is loaded. Hence, by suitably determining the combinations of setting of the timers 43, 49, the upset timing may be changed as desired.

Abstract: PROBLEM TO BE SOLVED: To shorten rising time till attaining specified control temperature by directly heating toner applied to paper by the surface of a halogen lamp having the structure of a rotating body roller and fixing it on the paper. SOLUTION: The halogen lamp 1 being a heat generating part whose both ends come in contact with connection terminals 5 made of phosphor bronze generates heat due to feed from the terminals 5. Since substance which becomes a heat insulating layer does not exist between the lamp 1 and the paper 9, heat responsiveness is enhanced. A bearing 3 is installed on a halogen lamp shaft 6 so as to rotate the lamp 1 with the traveling of the paper 9, whereby the lamp 1 is rotated. In order to facilitate the feed at that time, the bonding part of the lamp 1 to the terminal 5 is formed to be recessed and the bonding part of the terminal 5 to feed power to the lamp 1 is formed to be protruded, so that the lamp 1 is in a feed state even when it is rotated. The lamp 1 is pressured by a rubber roller 7 so as to fix the toner 8 on the paper 9.

Abstract: PURPOSE:To quicken and stabilize voltage control operation by varying the gain of a system voltage control circuit, based on a command value, in proportion to the magnitude of shortcircuit capacity of the system appearing when the power source is viewed from a system reactive power compensator. CONSTITUTION:System voltage is detected 301 and inputted to a feedback control circuit 302, then it is converted into a proper value which is fed to a gain operating unit 305 while simultaneously it is subtracted from a voltage command 300 for a voltage control circuit 303. The gain operating unit 305 calculates reactive power variation  Q( Q/ V) with respect to system voltage variation  V from the outputs of the voltage controller 303 and the feedback control circuit 302, and outputs a value proportional thereto. The output is employed in the voltage control circuit 303 for gain control. Then the voltage controlled 303 output is subjected to phase control 304, and the gates of thyristors 31, 32 are controlled thus controlling current flowing through a reactor 3. By such arrangement, system voltage can be controlled quickly and stably regardless of the system capacity.

Filed: 1986-01-08
Abstract: PURPOSE:To attain the second dynamic allocation of device numbers by adding a device number identifying circuit into a processor. CONSTITUTION:When the reset signal 60 is outputted from a controller 10, the processors 1-N are all set at input/output invalid signals. The processors containing the input/output invalid signals inputted to the input/output controller inputs IOMSKi2-in are inhibited for the input/output actions to the control signal given from a controller 10. Thus only a processor 1 containing the inverse signal inputted to the input/output control signal input IOMSKi1 from an inverter 500 can perform the input/output actions is response to the control signal of the controller 10. Here a specific number is set to a device number identifying circuit provided into each of processors 1-N. Thus it is possible to allocate again the device number of the processor 1.
