Abstract: 315,318. Universelle Cigarettenmaschinen-rabrik J. C. M³ller & Co. July 11, 1928, [Convention date]. Cigaratte-making, machines. - Cigarettes with tips of abnormal length are separated by electrical means controlled by an optical device such as a selenium cell, underneath which the cigarettes are passed. Fig. 1 shows a conveyer chain 1 carrying cigarettes c beneath a slotted screen 2, over which are arranged lamps b and a selenium cell z. The screen slot is arranged over the inner edge of the tip, when this is of normal length, so that when a tip of abnormal length comes under the slot, the cell z is effected so as to actuate an electromagnet e through a relay r. The magnet e moves axially the corresponding pin 7 in a rotating disc 6, so that this pin comes into the path of a lifter 8, which raises the faulty cigarette into a rotating gripper 10, by which it is transferred to a band 11. There may be two separating-devices, one for short tips, and the other for long tips. According to the Specification as open to inspection under Sect. 91 (3) (a) the band 11 may lead to a hopper which feeds another conveyer chain, the speed of which is slower than the chain 1, in order that the vacant spaces due to the removal of faulty cigarettes may be refilled from the hopper. This subject-matter does not appear in the Specification as accepted.

Filed: 1926-08-28
Abstract: 264,412. Armstrong, J. J. V., (Union Special Machine Co.). Aug. 28, 1926. Sack-sewing machines.-In a machine for closing filled bags, a carriage carrying a sewing head is moved positively along a track in one direction by an actuating device which is connected to or disconnected from the carriage by manually controlled means, means being provided to return the carriage to its initial position after such disconnection. The machine comprises a sewing head 88 supported by a carriage 38 adapted to ,run on a channel iron track 37 carried by brackets 35 at the top of movable vertical members 26. The members 26 slide in guides secured to vertical standards 24 and are moved to adjust the height of the sewing head 88 by nuts 29 secured to them and threaded by vertical pillars 30 secured to the standards 24 and connected at their lower ends by bevel gearing to a horizontal shaft 33 provided with a crank handle 34. The standards 24 are secured to a base platform 23 supported by side members 20, to one of which is pivoted a rock shaft 94 carrying a pedal 96 and an arm 97 adapted to turn a vertical rod 99. The rod 99 telescopes into a tube 101 and is secured to it by a pin-and-slot connection which compels the tuba to turn with the rod. At its upper end the tube 101 is journaled in the bracket 35 and through levers 106, 107 turns a rock shaft 82 journaled in brackets 83 on the bracket 35. To the shaft 82 is secured a swinging rod 81 adapted to engage between rollers 80, Fig. 7, on a lever 58 pivoted at 59 to the carriage 38. This lever,. through a screw 57, cross-lever 54, and arm 51 operates a clutch member 45 on a vertical shaft 47, Fig. 8, journaled in a table 49 supported by the carriage 38, the other clutch member 44 being mounted on a shaft carrying a pinion 42 which meshes with a rack 41 secured in the channel iron track 37 so that rotation of the pinion moves the carriage along the track 37. The shaft 47 is driven by worm gearing from a shaft 61, to the end of which is secured a friction wheel 73. A motor 68 which actuates both the carriage and the sewing head is provided with a friction wheel 69 adapted to drive the friction wheel 73 when an idler wheel 70 is drawn downwards. To effect this the idler wheel is mounted on an arm 71 slidably pivoted on a pin 72 and formed with an arm 74 secured by a spring 75 to the lever 58. In operation, depression of the lever 58 by the pedal 96 puts in the clutch 45 on the shaft 47 and operatively connects the motor, through the wheels 69, 70, 73 to that shaft. When the pedal is raised, a stud 78 on the lever 58 engages the lower end of the arm 71 and lifts it, thus positively releasing the idler wheel 70, and the carriage 28 returns to its starting position by gravity, the track 37 being inclined for this purpose. A table 111. Fig. 3, may be affixed to the standards 24 to accommodate small bags, and if only one of these is to be sewn at a time, a stud on the carriage 38 is raised to lift permanently the lever 54 and thus disconnect the carriage from its driving mechanism.

Patent GB-670123-A (GB)
Title: Improvements in or relating to thermionic valve oscillators adapted to be frequency modulated
IPC: H03C3/14
Filed: 1949-08-19
Abstract: 670,123. Frequency modulation; frequency shift telegraphy. GENERAL ELECTRIC CO., Ltd., and WATKINS, T. B. Aug. 17, 1950 [Aug. 19, 1949], No. 21616/49. Class 40 (v). The operative frequency of a valve oscillator is modulated or shifted by connecting the load resistance of a cathode-follower valve stage through a reactive impedance across the oscillator tuned circuit or a part thereof, the modulation signal being applied to a control grid of the cathode-follower stage. For frequencyshift telegraphy, pulses representative of marks and spaces are applied directly to the control grid; for telephonic or like modulation, the signal is used to amplitude-modulate the oscillation, which is then applied to the control grid. In the telegraphy circuit, Fig. 1, the oscillator circuit comprises a coil 2 and two equal condensers 3, 4, the junction of which is connected through a smaller condenser 8 to the cathode of the cathode follower valve 5. The tuned circuit is earthed at one side through a bias battery 14 and is connected on its live side to the grid of a further cathode-follower stage 9. The cathode of the latter is coupled to the grid of a valve 10 whose cathode is connected to that of the valve 5. When positive telegraph pulses, e.g. marks, are applied to the grid of the valve 5, sufficient bias is developed across the resistor 6 to block the valve 10. In this condition, the condenser 8 places an effective positive capacity across the condenser 4 and the frequency is decreased. When negative pulses, e.g. spaces, are applied to the grid of the valve 5, the valve 10 is operative and feeds oscillatory voltage to the cathode of valve 5. This voltage is higher than that at the junction of the condensers 3, 4 and the condenser 8 then places an effective negative capacity across the condenser 4 and thus increases the frequency of the tuned circuit. Figure 2 shows a suitable circuit for telephony and like signalling. The tuned circuit 20 and the cathode-follower stage 21 are arranged as in Fig. 1, except that the condenser 22 is substantially smaller than the condenser 23. The carrier oscillations in the circuit 20 are applied to a balanced amplitude modulator 25, to which the audio-signal 24 is also applied. The resulting side-bands are added to the carrier at 26 and applied to the grid of the valve 21. Oscillations varying in amplitude with the signal thus appear at the cathode of the valve 21, causing the effective capacity of the condenser 30 to vary in the rhythm of the audio signal and giving a corresponding modulation to the frequency of the carrier oscillations.
