Patent GB-114776-A (GB)
IPC: G03B31/00
Abstract: 114,776. Rogers, H. W. Oct. 25, 1917. Phonographs working in association with kinematographs.-A phonograph is started at the required moment by clutching its shaft to that of a kinematograph projector, the clutch being actuated eleotro-magnetically or mechanically by suitably-placed projections or slots on the kinematograph film. When one phonograph record is is completed, its clutch is disengaged, and a second phonograph may be connected to the kinematograph mechanism. As shown in Fig. 1, the projector is provided with a bracket 6 supporting a shaft 4 driven by the projector mechanism. The shaft 4 drives a clutch member 9 by means of a feather key 10, Fig. 6, the other clutch member 14 being loose on the shaft 4 and geared to a shaft 23 connected to the phonograph 100. The clutch is kept out of engagement by a spring 16, and may be engaged by a lever 29, a pin 11 then entering one of a ring of apertures 12. The film 47, Fig. 3, is provided with one or more bosses 48 which, on passing a pivoted member 44, complete a battery circuit through an electro-magnet 38 which attracts its armature 28 and throws in the clutch. The member 44 is pressed against the film 47 by a spring 46 and may be prevented from returning, after the passage of the boss 48, by a detent 49. In a modification, the film passes between a fixed roller 55, Fig. 4, and a roller 56 carried by a switch lever, the passage of the boss 48 closing the circuit of the electro-magnet 38 at the contacts 57, 58. The clutch 9 is locked in its operative position by a latch 34, which may be released by energizing a magnet 52, the circuit of which is completed when a second boss, out of alinement with the boss 48, closes a second switch. Fig. 8 shows a modification in which the clutch 9 is actuated mechanically. A spring-actuated plunger 81 is held in its innermost position by a detent lever 75 bearing against the film. When a slot in the film passes the lever 75, the plunger 81 is forced outwards by a spring 82 and actuates the clutch lever 85. When two or more phonographs are used, the first machine is disconnected and the second machine put into action by a lever lying in the path of the stylus of the first phonograph. In another modification, shown in Fig. 12, the first phonograph is started by momentarily closing the circuit of electro-magnet 38<1> at the switch 57'. The subsequent closure of the switch 58<1> energizes the magnets 52<1> and 38<a>, the former releasing the lever 29' and disconnecting the clutch C, and the latter actuating the lever 29a and throwing in the clutch C'. A further closure of the switch 57<1> energizes the magnets 52<a>, 38<1> thus disconnecting the clutch C<1> and engaging the clutch C.

Title: Radar data smoothing system
IPC: G01S13/66
Filed: 1973-03-09
Abstract: 1408494 Radar SELENIA INDUSTRIE ELETTRONICHE ASSOCIATE SpA 9 March 1973 [13 March 1972] 11647/73 Heading H4D A radar tracking system comprises a wideband channel and a narrow-band channel, each providing predicted target position and speed signals, a display showing the wide-band predicted position and the narrow-band predicted speed, a gating control operated by the wide band predicted position signal and a comparator comparing the actual target position with the narrow-band predicted position in order to update the narrow-band predicted position signal by applying the wide-band signals to the narrow band channel. A radar set RR repeatedly scans a target and provides position data signals to wide- and narrow-band channels CP, CR. These channels provide predicted values for position and speed thus (Fig. 3, not shown), Counter CN determines when the radar has made N 1  scans and enables gate CB, thus passing the radar data signals to the narrow-band channel CR. The wide-band predicted signals pb, vb pass through gate CA and the narrow-band channel begins to produce its predictions sp, sv. Signal sp is continuously compared with the measured target position in comparator CPS. If the error is small, the narrow-band predictions are based on the previous predictions (gate CA disabled). If the errors are above a preset threshold for three scans, gate CA is opened and the wide-band predictions are used to up-date the narrow band channel. After a number N 2  of scans, counter CN enables a speed comparator CV which determines whether the predicted target speed is less than V 1 , greater than V 2  or between the two (V 1 , V 2  being preset speeds). According to this determination, one of three sets of constants a, # are selected for the narrowband channel. Initially, the widest response of the three selections is used.

Abstract: 1,023,558. Cold separation of gas mixtures- LINDE A.G. March 23, 1964 [March 21, 1963; March 11, 1964], No. 12111/64. Heading F4P. Separation of condensible constituents, e.g methane from a mixture thereof with hydrogen, e.g. coke oven gas prior to working the crude hydrogen so formed with liquid nitrogen in a column 19, Fig. 1 (not shown), to produce ammonia synthesis gas in lines 41, 43 is effected by cooling coke oven gas leaving a compressor 4 in one of three cyclically interchangeable regenerators 1 . . . 3 or reversible heat exchangers thereby precipitating the methane in, say, regenerator 1 from which it is vaporized in the next cycle by vaporized sump liquid, warming to ambient temperature at least the major part of the cold crude hydrogen by passing it from the cold to the warm end of regenerator 3 thereby cooling the same and finally recooling the crude hydrogen by heat exchange at 26 in indirect countercurrent flow with product hydrogen and nitrogen mixture in line 41. Crude hydrogen leaving regenerator 1 through a line 6 serves to liquefy nitrogen supplied by a compressor 31 before being expanded in a turbine 13 and warmed in regenerator 3. The so warmed crude hydrogen is recompressed at 24 before traversing exchanger 26 and is then further cooled at 21 by sump liquid, freed of liquified residual impurities in a separator 29 and fed through a line 30 to column 19. The contaminated regenerator is cleaned by passage therethrough of sump liquid having been vaporized in an exchanger 21 having a discharge line 22 and the mixture issuing from the warm end of said regenerator through a line 16 is joined by vaporized liquid from separator 29 and used as fuel gas. During the succeeding cycle regenerator 1 is freed of condensed constituents, regenerator 2 is cooled whilst regenerator 3 serves to cool the feed gas mixture. During the third cycle regenerator 1 is cooled, regenerator 1 is on stream whilst regenerator 3 is cleaned. In a modification, washing with liquid nitrogen is eliminated and column 19 is used to rectify the crude hydrogen for the production of fume gaseous hydrogen.
