Abstract: 963,095. Sawing. SOC. DE CONSTRUCTIONS MECANIQUES ET AERONAUTIQUES DE LA MAYENNE. June 25, 1963 [July 24, 1962], No. 25196/63. Heading B5L. A flying cutting-off machine comprises a saw 1 carried on an arm 4 having one end connected by a pin 8 on an adjustable crank 9 and the other end 5 guided to describe either a straight line or an arc of a circle of relatively large radius so that the cutting edge of the saw, located between the ends of the arm, describes a closed curve D approximating an ellipse or oval, one arc of which intersects the path A of the workpiece while another arc is remote therefrom for the return phase of the saw. The end 5 of the arm may be connected to a straight or curved slide or, as shown, to one end of a lever 6 pivoted at 2 to a frame 12 of the machine. The pin 8 at the other end of the arm is adjustably carried by the crank 9 which is carried by a shaft 10 supported in a bearing 11 adjustable transversely of the path A of the workpiece along a slide 13. The shaft 10 is connected directly or by bevel gearing to a flexible shaft 14 having its other end connected directly or by bevel gearing to a disc 16 engaging the workpiece, which may be flat tube issuing from a profiling machine B. The workpiece is supported by a grooved wheel which may be the last element of the profiling machine. In operation, the size of the disc 16 is selected to have a circumference corresponding to the desired lengths to be cut from the workpiece, and the length of the crank 9 is adjusted to substantially equal the radius of the wheel 16. As the workpiece issues from the profiling machine B, the wheel 16, which is pressed against the workpiece by a spring, causes the crank 9 to rotate and the saw 1, which is driven by a flexible drive 22 from a motor 23 moves in the path D to cut the workpiece and return to its initial position.

Title: Photographic printing apparatus
IPC: G03B27/73
Filed: 1960-01-13
Abstract: 945, 598. Photo-electric control of photographic printing. PAKO CORPORATION. Jan. 13,1960 [Jan.30, 1959], No. 25245/61. Divided out of 945, 593. Drawings to Specification. Heading G1A. The description is substantially identical with that appearing in Specification 945, 593 but the claims are directed to the feature of providing colour convecting circuits in the exposure timing circuits which are arranged in such a manner that a change of exposure by a given amount in one direction for one colour component is automatically accompanied by changes of exposure in the other direction, each of half the amount, for the other two colour components, whereby the total exposure, and hence print density, remains unchanged. The exposure timing circuits include capacitors which are charged by pulses from a photo-electric cell responsive to a sample of the light forming the printing image, thyratrons, one for each colour component, being fired at their grids to actuate means to terminate the exposure in the colour components when the capacitors acquire potentials sufficient to overcome the bias levels set at the cathodes. The colour correcting circuits determine the cathode biases and comprise, for each colour component, a main resistor and two auxiliary resistors mechanically coupled so that increasing the value of the main resistor reduces the value of the auxiliary resistors, and vice versa, the changes for the auxiliary resistors being half that of the main resistor. The main resistor is connected in the cathode circuit of the thyratron for the related colour component, whilst the auxiliary resistors are each connected in the cathode circuit of a different one of the other thyratrons. Specifications 945,597,945,599 and 945, 600 also are referred to. Reference has been directed by the Comptroller to Specification 879, 729.

Title: Operating circuit for an electrostatic precipitator
IPC: B03C3/68
Filed: 1966-06-10
Abstract: 1,083,788. Electrostatic precipitators. KOPPERS CO. Inc. June 10, 1966 [June 11, 1965], No. 26082/66. Heading H2H. In an electrostatic precipitator, a series of sampling pulses of selected higher magnitude than the normal working voltage are applied to the electrodes and the voltages are adjusted according to the presence or absence of sparking in the precipitator. The working voltage is applied in the form of a series of pulses from a capacitor 7, changed through a resistor 1 and diode 13 and discharged through the electrodes and diode 12 by the firing of a tube 4. A similar circuit operated by tube 5 provides interleaved sampling pulses. Control voltages representative of the precipitator currents from resistors 23, 24 are passed through diodes 25, 26 to a capacitor 27, the voltage across which is compared with a reference 30 and the difference passed to an amplifier 31. If no sparkover occurs, a motor 35 increases the working and sampling voltages until the sparkover of the sampling pulses is sufficient to arrest the motor. If the sparkover level drops and both voltages cause excessive sparkover, the capacitor 27 voltage causes a reversal of the amplifier input signal and hence reversal of the motor 35. The sampling pulses may be equal to or narrower than the working pulses and may be numerically equal to or less than the working pulses. The tubes 4, 5 are fired by pulse generators 43, 44, energized from variable frequency phase displaceable alternations 40, 41. The working pulses are inhibited during the sampling pulses. In an alternative arrangement (Fig. 2, not shown), two sets of sampling pulses are generated of differing amplitude from tubes (5), (6), from which the control voltages are derived.
