Title: Driving mechanism for power-operated type-writers
IPC: B41J23/12
Filed: 1962-06-22
Abstract: 1,012,834. Typewriters. SOC. DE MECANOGRAPHIE JAPY. June 22, 1962 [July 6, 1961], No. 24169/62; Heading B6F. In a power-operated typewriter wherein actuation of the type levers, carriage spacing, carriage return &c. is effected by bringing camplates 8, Fig. 2b, into contact with a constantlydriven shaft 3 having a rubber-like covering 4, the periphery of each cam plate (a) is smooth and is arched as shown, (b) has a friction coefficient of not less than 0À5 with respect to the rubber covering, and (c) has a resistance to abrading which is less than that of the covering. Wear thus occurs mainly on the cams which are easily replaceable. The cams may be made of polystyrene or acrylglass, In one, arrangement, Fig. 5, employing such cam plates 33 for actuating type levers 23, each plate 33 is carried by a member 34 pivoted at 18 and connected by a spring 26 to a lever 17 linked to the type lever. Actuation by a key of a member 24 causes the cam plate to be pivoted into contact with the driven shaft 27 to operate the type lever. A stop 35 pivoted at 36 on a bar 40 and pressed by a spring 37 against an adjusting screw 39 limits the movement of the cam plate. A part 30 on the lever 17 can be bent to vary the initial spacing of the cam plate from the shaft. The bar 40 which carries all the stops 35, is pivoted about the shaft 36 and has an arm 41 with a roller 42 held by a spring 46 in one of a number of different-depth depressions 47 in a member 43. Turning of the member 43 by a rod 44 serves to vary simultaneously the positions, of all the stops 35 for varying the type impacts according to the number of carbon copies required. The lengths of the cams vary with the size of the type characters corresponding thereto so as to effect the required printing impact. As shown in Fig. 6, the stops 54 normally rest under gravity against a bar 68 and when one is engaged by an operated cam plate 33 it moves upwardly until it abuts against one of two adjusting set-screws 52, 53 carried by a pivoted member 51, the member 51 being turned when case shift is initiated so as to bring the appropriate set-screws into operative position. A spring 60 engaged by the stop 64 causes a gradual disengagement of the camplate 33 from the driving roller 27. In a further construction, Fig. 7 (not shown), the arrangement shown in Fig. 6 has incorporated therein devices as described with reference to Fig. 5 for effecting simultaneous adjustment of all the cam-plates in addition to individual and case shift adjustments.

Title: Improved Method For Measuring The Precision of Gears
IPC: G01B7/28
Filed: 1966-05-31
Abstract: 1,153,284. Determining inaccuracies in gear transmissions, electrically. VYZKUMNY USTAV OBRABECICH STROJU A OBRABENI. May 31, 1966 [June 2, 1965], No.24198/66. Heading G1N. Relates to a modification of the method of testing the accuracy of gears described in Specification 910,939. The transmission gear to be tested comprises toothed gears 1, 2 (as shown) on shafts 3, 4 respectively and errors in angular velocity ratio are to be determined. The method of magnetically recording two reference tracks of sinusoidal waveforms on drum 6 and two similar tracks, which reflect the non-uniformity or errors in velocity ratio of the gears, on drum 10, is stated to be as in Specification 910,939. The ratio of the number of complete waveform cycles per track on drum 6 to the number on drum 10 corresponds to the gear ratio. Whereas in the Specification 910, 939 the gears are rotated while the outputs of the two reference pick-ups (at drum 6) are subtracted to give a first "difference frequency" and the outputs of two pickups at drum 10 are subtracted to give a second difference frequency of the same value as the first but shifted in phase according to inaccuracy of the gears, in the present Specification the gears are not rotated the drums being rotated in a direction to eliminate the factor dependent upon the speed of the gears as shown mathematically below:- With the motor 18 driving gears 1 and 2 and pickup heads 5, 9 fixed thereto at K 1 , K 2 , revs./sec. respectively, the gear ratio i = K 1 /K 2 . Drums 6, 10 are driven by motors 7, 11 respectively at n 1 , n 2  revs. /sec. The number of complete sinusoid cycles on drum 6 is Z 1  and on drum 10 is Z 2  so that i = Z 2 /Z 1 . Signals at the following frequencies would be induced in the pick-up heads. Stationary head 8: f 1  = Z 1 n 1  Mobile head 5: f 1 ' = Z 1 n 1  Œ Z 1 K 1  Stationary head 12: f 2  = Z 2 n 2  Mobile head 9: f 2 ' = Z 2 n 2  Œ Z 2 K 2  Since i = K 1 /K 2  = Z 2 /Z 1  then Z 1  K 1  = Z 2  K 2    To eliminate Z 1  K 1  and Z 2  K 2  the drums are rotated in an appropriate direction and difference frequencies #f and #f' are obtained as follows: - Subtracting signals in heads 8 and 12 #f = f 2 -f 1  = Z 2 n 2 -Z 1 n 1 , = Z 1  (i.n 2 -n 1 ) Subtracting signals in heads 5 & 9. #f' = f 2 ' - f 1 ' = Z 2 n 2  - Z 1 n 1  = Z 1  (i.n 2  - n 1 ) # #f = #f' Thus the speed of the gears can be zero. In an alternative method of obtaining difference frequencies the frequencies at heads 8 and 12 are added to a frequency F from an auxiliary oscillator (not shown) and the frequencies of signals at heads 5 and 9 are subtracted respectively from these sums. The phase difference between the two difference frequency signals is measured as described in Specification 910, 939, as an indication of the gear inaccuracies.

Convention date, Sept. 16, 1931. [Classes 40 (iii) and 40 (v).] The suppression of direct-current components in television signals before or during transmission is compensated by a supply of direct current controlled by fluctuations produced in the received signals. The current from the photo-electric cell 7, Fig. 1, fluctuates in a manner indicated by the curve c, Fig. 3, and by scanning a black strip beside the object 6, or by making the aperture 8, Fig. 1, smaller than the width between two apertures 3 in the scanning disc 2, a fluctuation of amplitude I, Fig. 3, is periodically produced which is proportional to the D.C. component. The received signals, Fig. 4, lack the D.C. component and are amplified by valves 13 and 14 and applied to the neon lamp 19. The valves 13, 14 are coupled by a compensating circuit comprising a rectifier 16, a condenser 17, and a high resistance 18. The fluctuation of amplitude a, Fig. 4, is rectified at 16 and the condenser 17 is charged to reduce the potential applied to the grid of the valve 14 whose plate circuit is supplied with a corresponding D.C. The resistance 18 allows the charge on condenser 17 to leak away so that the condenser is recharged by the next signal produced by scanning the black strip. The rectifier 16 may comprise a twoelectrode thermionic rectifier (Fig. 5, not shown). When transmitting on a carrier wave, the D.C. components are suppressed in amplification and are replaced by a compensating circuit identical with that of Fig. 1, before modulation (Fig. 6, not shown).
