Abstract: 1,141,242. Cutting pipes by fusion. VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY I KONSTRUKTORSKY INSTITUT AVTOGENNOGO MASHINOSTROENIA. 23 March, 1967, No. 13750/67. Heading B3V. [Also in Divisions G1 and G3] An apparatus for cutting pipes includes a means for rotating a pipe and a means for moving a cutter along the pipe, the two means being controlled by an optical tracking device responsive to a scale drawing of a planar development of the three-dimensional contour being cut. As shown, Fig. 2, a pipe 2, gripped by a clamp is revolved by a motor 9 through gearing 8. A carriage 1 with a gas cutter is linearly translated by a bogie running on rails, Fig. 1, (not shown), by a motor 4 driving through gearing 5. A table 11 supports a planar development drawing of the contour to be cut and is positioned in synchronism with the movement of the cutter and rotation of the tube by gear drives 24-27 and 28-31 respectively. The contour edge is scanned by a photo-electric device 12, incorporating a motor driven disc 14, Fig. 3, provided with a hole through which the light reflected from the drawing passes to a photo-multiplier. The output from the photomultiplier, when positioned over the border of a contour, comprises rectangular impulses of alternate widths indicative of the deviation of the scan from the contour edge. The impulses are amplified in unit 17, differentiated in unit 18 and fed to a peak impulse selector 19. The peak impulses are fed to a monostable multivibrator 20 generating equal width pulses which are amplified and fed to a Scott-Walter connected phase-sensitive unit 21, from which sine cosine component voltages are derived and applied to power amplifiers 22, 23 for control of the motors 9, 4, Fig. 2. The phase-angle of the , output of the multivibrator 20, which is representative of the angle between the pipe axis and the tangent to the counter, is applied to a phase sensitive device 35 controlling a motor 32 rotating the carriage 1 through gearing 33; feedback to the device 35 being provided from a phase shifter 37. The motor rotates the carriage so that the plane of the cutter is perpendicular to the tangent contour of the line at the point being cut.

[Also in Division G4] A photo-electric system for deriving two different signals from phosphorescent and fluorescent markings within a common area, uses as a distinguishing criterion the rate at which the intensity of secondary light emission increases. A letter 1, Fig. 5, bearing fluorescent and phosphorescent marks 3, 4 is traversed past a slot 6. Ultraviolet light from a mercury vapour lamp 7 passes through filters 12 to strike the marks 3, 4, producing secondary radiation which passes through a filter 13 to a photo-cell 8. The radiation detector pulses are of the Form 17, Fig. 8a, for fluorescent marks and 18 for phosphorescent marks. These pulses are differentiated to give a signal as shown in Fig. 8b and clipped at a level Us to produce pulses indicative of the fluorescent markings only In a modification, the speed of the letter and the size of slot 6 are so chosen with respect to the properties of the fluorescent and phosphorescent material that the peak of the phosphorescent pulse 22 Fig. 9a is less than that of the fluorescent pulse. The differentiator may then be omitted. In a further modification the differentiator is replaced by an integrator.

Title: Improvements relating to automatic regulation of clutch capacity on motor vehicles
IPC: F16D48/06
Filed: 1956-05-11
Abstract: 795,591. Controlling clutches. DAIMLERBENZ AKT.-GES. May 11, 1956 [May 14, 1955], No. 14762/56. Class 80 (2). The torque transmitting capacity of a motor vehicle clutch is determined in relation to the engine torque available and is regulated by control means adapted to detect the instantaneous engine torque, the maximum torque transmissible by the clutch being slightly above maximum engine torque and the minimum torque capacity being above the maximum braking torque when the engine is overrun, this minimum being maintained while power is transmitted from the vehicle to the engine. An engine 1 normally rotating in the direction of the arrow 2 drives through an electromagnetically regulable clutch 6 which is fed with current from a source 9 through a resistance 10. The engine is mounted by a rubber packing piece 4 to a fixed part 5 of the vehicle, and carries an arm 12 having a sliding contact 11 connected to one end of the resistance 10. The line 15 represents the position of the contact 11 under zero torque conditions ; the line 14 represents the position full overrun braking and line 16 the equivalent positive torque. Increase of engine torque above the line 16 results in a decrease in the value of the resistance 10 with consequent increase in clutch torque capacity until at 17 the clutch torque is at a maximum corresponding to maximum engine torque. In a second embodiment the resistance is shorted out from just above the line 16 to provide two clutch torque capacity conditions only.
