Title: Cigar mouthpiece assembly
IPC: A24C5/47
Filed: 1969-01-02
Abstract: 1,211,992. Cigar mouthpiece assembly. A.M.F. Inc. 2 Jan., 1969 [11 Jan., 1968], No. 319/69. Heading A2C. A mouthpiece is attached to a cigar by applying a peripheral reinforcing band to the juncture of a cigar blank and mouthpiece, and then applying a wrapper over said blank and said band. The band is preferably of reconstituted tobacco. A suitable device for carrying out the process is shown in Fig. 1 wherein a continuous strip of reconstituted tobacco 24 is fed to a receiving platform 48. The strip is retained on the receiving platform by a vacuum created in the vacuum source 56, and transmitted via three way valve 52 and conduit 50 to the receiving platform. As the strip is positioned on the platform, the transfer head 68 swings to a position above the platform and lowers to engage the strip. This movement is followed by actuation of the cutting knife 46 to sever a band from the strip 24. A glue dipper rod is then actuated to apply glue to the underside of the projecting end portion of the band completely across its width. Simultaneously there is a transfer of vacuum from the platform 48 to the transfer head 68, which head is then raised slightly and moved through the arcuate path 72 to a delivery position relative to the wrapping device having mounted therein a pre-assembled cigar blank 14 and mouthpiece 16. On reaching the delivery position, the head 68 is tilted to place the glued end of the band against the periphery of blank 14 and mouthpiece 16. The vacuum source is disconnected from a head 68 and the band wraps around the juncture of the blank and mouthpiece. An outer wrapper is then attached to the blank. The movements of the various parts described above, and the vacuum application means, is controlled by movement of the cams 76-77, 78 and 79, each of which is mounted on the rotatable shaft 80. These cams are connected to the parts and vacuum application means by linkages 84, 85, 90, 82 and 91.

Title: Power supply for x-ray apparatus
IPC: H05G1/20
Filed: 1969-01-03
Abstract: 1,215,282. Supply systems for X-ray apparatus. WESTINGHOUSE ELECTRIC CORP. 3 Jan., 1969 [23 Jan., 1968], No. 468/69. Heading H2H. A control circuit for supplying an X-ray tube from a polyphase source includes an H.T. transformer controlled by semi-conductor switching devices and also arrangements for preventing saturation of the transformer and ringing effects. As shown in Fig. 1, a three-phase 60, Hz supply A, B, C is applied through an autotransformer 10 and a thyristor switching circuit 12 to a transformer-rectifier 14 which produces trains of pulses for operation of an X-ray tube 16. Before each pulse is produced, a preset power supply 22 is switched on to energize the transformer in such a way that saturation will not occur when the circuit 12 is switched on. A timing circuit 28 determines the duration of the pulses, and is itself controlled by a circuit 24 which prevents starting pulses from a firing angle detector 26 from reaching the timing circuit unless a signal from a command circuit 18 is present. This preventive circuit 24 also triggers the preset power supply 22. In operation, a signal from the firing angle circuit 26, indicating an appropriate phase of the supply, passes through the preventive circuit to initiate a timing sequence in the circuit 28. Immediately, two of the switching thyristors, Q C  and Q A1 , are gated on so that an output pulse begins, and 60 degrees later in the waveform of the supply the remaining thyristors are gated. This delay in the switching prevents ringing effects and helps to stop the transformer saturating. After a predetermined time, controlled by a variable resistor in the circuit 28, a reset signal is produced, switching off the timing circuit 28 and again turning on the preventive circuit 24 and so terminating the pulse. Manual termination may be achieved in a shorter time if desired by actuating a signal from the command circuit 18. If pulses shorter than 7 msec. are required, a manual switch in the timing circuit is moved to a position wherein only some of the switching thyristors are supplied with gating pulses.

Title: Improvements in and relating to electric motor control systems
IPC: H02P7/34
Filed: 1950-01-10
Abstract: 673,177. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 10, 1950. [Jan. 22, 1949] No. 633/50. Class 38 (iii). [Also in Group XXXV] In a Ward-Leonard set for operating oil-well drills, the motor 1 and generator 2 are excited by cross-flux generators 12, 13, either of whose excitation may be made dependent on the main load current in the series loop 18 to produce constant motor power for hoisting the drill, or constant motor torque for lowering the drill during boring. For hoisting, the solenoid 14 is energized to close switches 15, 16 and engage the lower contacts of switch 17 so that the signal voltage appearing across the resistor 20 is added to that from a manually variable resistor 23 and energizes the field winding 12c of the crossflux exciter 12. An increase of hoisting load. causes the motor current to rise which, in turn, increases the volt-drop across the resistor 20 and thus increases the motor excitation to reduce its speed. By this means the motor output power is maintained constant in spite of variations in lifting effort. Meanwhile, the switch 17, being in the lower position, connects the field winding 13c of the generator exciter 13 to a constant voltage supply from a manually adjusted resistor 25 controlling the generator output, by which means the motor power may be pre-set. For drilling, in which the motor acts as a constant torque drag generator maintaining constant pressure on the drill, switches 15 and 16 are opened so that the motor field is constant and depends only on the setting of resistance 23, whilst the switch 17 is in the upper position so that the generator excitation depends on the control voltage appearing across resistance 29 in the series loop 18. This voltage is matched against a fixed opposing voltage appearing across the resistance 25, so that the generator output current, and therefore the motor torque is maintained constant. Alternatively, a strain gauge attached to the drill and controlling a rheostat may be used to control the generator exciter and maintain the motor torque constant. The motor speed is limited during hoisting and drilling by matching the voltage from a tachometer generator 27 with a fixed voltage from adjustable resistances 28 and 30 respectively through rectifiers 28a and 30a, the resultant voltages being fed to exciter field 13d in such a manner as. to reduce the motor speed.
