Abstract: 1,258,883. Electro-photographic copier. KONISHIROKU PHOTO INDUSTRY CO. Ltd. Feb.20, 1970 [Feb.24, 1969], No.8407/70. Heading G2H. A photo-conductive paper sheet 9a secured to an endless belt 10, is held stationary while a frame 1 moves thereacross to charge the sheet and expose it to an original on a platen 7; sheet 9a then being fed past developing 12, transfer 16, 17 and cleaning 25 stations. A sheet 9b undergoes a similar process. Frame 1 supports a lamp 4, a mirror 3a, 3b, a lens and rectangular prism essembly 2, a hinged diaphragm 5 and a corona charging device 8. After exposure rollers 11a. 11b drive the sheet on belt 10 past the developing station 12, into contact with a transfer paper fed from a stock 13, and past a transfer corona discharge 16. The sheet 9a is then fed to cleaning station 25, while the transfer sheet, separated by a unit 17, is fed by belts 20, 21 to a heat fixer 22. Preferably, belts 20, 21 travel more slowly than the belt of assembly 17 so as to prolong the time in fixer 22; the spacing between sheets 9a, 9b avoids congestion in this case. The sheets 9a, 9b are secured to the belt 10 by releasable devices Figs. 2, 3, 4 (not shown). Unit 17 which comprises endless perforate belts around a suction tank, is automatically pivotedaway from belt 10 by rotating cams 82a, 82b; Fig. 5 (not shown) when the ends of sheets 9a, 9b pass thereby, so as to avoid contact between unit 17 and the projecting securing devices.

Abstract: 1333777 Automatic control of electro slag furnace BRITISH IRON & STEEL RESEARCH ASSOCIATION 3 Dec 1971 [3 Dec 1970] 57452/70 Heading G3R In electro slag refining equipment, fed from an A.C. source 3 via transformer 4 and constant current device 5 e.g. a saturable reactor, the actual power to a consumable electrode 1 is measured by transducer 7 compared with a desired reference from potentiometer 10, any error from comparator 9 driving motor 12 to raise or lower the electrode. The voltage across the slag bath 20, indicative of the electrode position, is compared with limits as set by potentiometers 18, 19. If the desired power is, for example, such that the electrode is driven clear of the slag bath, the voltage across the bath increases due to arcing until the limit set by potentiometer 18 is exceeded, when relay 21 is energized, to open switch 25 isolating the motor 12 from the comparator 9, to activate motor 27 increasing the current through device 5 i.e. to the electrode, and to close switch 22 driving motor 12 to lower the electrode, until the voltage across the slag bath is less than the value set by potentiometer 18. When relay 21 is reenergized and control of electrode position returned to the comparator 9. Thus the required power demand is met by the electrode moving between predetermined position limits. The electrode position and current are similarly modified if the voltage across the slag bath falls below the value set by potentiometer 19. The potentiometers 10, 18 and 19 may be variable. In a further embodiment Fig.2 (not shown) the electrode may be repositioned in the upper region of the slag bath if it moves outside the limits set by potentiometers 18, 19.

In the embodiment described a win during the first game or group of games pays a prize and also energizes a stepping relay which is then advanced one step on each game of the further group of games up to a predetermined limit, the relay then being zeroized. Stepping of the relay also serves to modify the switching condition in the payout unit so as to alter the amount dispensed in respect of a win during the further group of games. The number of games in the first group is determined by the amount of the original stake and the machine may be arranged so that in the event of a win during the first group of games the rest of the games in that group are forfeit. Similarly the rest of the games in the further group may be forfeited after a win in one of the games of that group. An indicator device connected to the stepping relay is provided to inform the player how many games of the further group have been played.

Inventor: LAROIA RAJIF
IPC: H04W72/04
Filed: 2000-03-06
Abstract: An orthogonal frequency division multiplexing (OFDM) based spread spectrum multiple access system using offsetting between cells, and in particular, the use of tone offsetting and time offsetting, is disclosed. More specifically, frequencies that define the tone set of one cell is offset from the frequencies that define the tone set of at least one adjacent cell. In other words, if a first base station is using tones F1, F2, ..., FN within a frequency band, then a second base station adjacent to the first base station uses tones F1+ DELTA f, F2+ DELTA f ..., FN+ DELTA f within the same frequency band. Furthermore, the symbol timing of the base-station of one cell may be offset from the symbol timing of the base-station of an adjacent cell. Thus, if a first base station starts successive symbols at times T1, T2, and T3, then a second base station adjacent to the first base station starts its respective corresponding successive symbols at times T1+ DELTA t, T2+ DELTA t, and T3+ DELTA t. For example, in a cellular system with hexagonally shaped cells, the tone sets of two adjacent cells are offset by 1/3 of the spacing between adjacent tones, and the symbol timings of two adjacent cells are offset by 1/3 of a symbol period. Advantageously, the intercell interference is more uniformly distributed among users in a cell. <IMAGE>
