Title: Improvements in or relating to time-base control arrangements for oscillographs
IPC: G01R13/04
Filed: 1938-11-12
Abstract: 521,221. Recording-apparatus. FIDES GES. FUR DIE VERWALTUNG UND VERWERTUNG VON GEWERBLICHEN SCHUTZRECHTEN GES. Nov. 12, 1938, No. 32973. Convention date, Nov. 12, 1937. [Class 106 (iv)] [Also in Group XXXVI] An oscillograph for recording processes of brief duration has a tilting mirror for deflecting the beam of light on to a recording surface and producing the time-base movement, and also a polygonal mirror having an adjustable speed of rotation for producing the time base movement for visual observation, the tilting mirror being operated by an adjustable energy accumulator acting on a flywheel mass so as to accelerate this before the beam impinges on the recording surface, and the means for regulating the energy accumulator being mechanically coupled with the regulating means for the polygonal mirror so that the time-base movement is the same during recording and observation. A beam of light is reflected from the oscillograph mirror 1 and a tilting mirror 4 to a fixed cylindrical recording surface 5. The mirror 4 is mounted on a shaft 6 which also carries a flywheel 7, a locking disc 8, and a disc 9 round which is wound a chain 10 terminating in a link 11 which fits over a fixed pin 12. A tension spring 13 engages the link 11 and is connected to a band 16 fixed to a cam disc 17. The shaft 6 is held in its starting position by the engagement of a lever 23 with a step in the locking disc 8 and is disengaged by the depression of a key 25. Depression of a tensioning key 26 engaging a pin 27 on the flywheel 7 returns the locking disc 8 to its locking position and tensions the spring 13. In this position the light beam does not fall on the recording surface 5. On depression of the releasing key 25 the spring 13 accelerates the flywheel 7 until the link 11 engages the pin 12, in which position the light beam strikes the recording surface 5. The shaft 6 then continues its rotation at constant speed under the action of the kinetic energy of the flywheel 7 until a pin 28 engages between brake springs 29, at which point the beam of light has passed over the recording surface. A counterbalance 31, or a weight acting on a pulley, may be provided for compensating for friction. Rotation of a knob 21 tensions the spring 13 to adjust the speed of rotation of the mirror 4 and also adjusts 'a rheostat 20 which controls the speed of the polygonal mirror (not shown).

Convention date, Nov. 29, 1930. [Class 143.] Pendulum-weight apparatus. - In an automatic weighing scale of the type having two pendulums on which the load (or a force which varies with the load) acts through a lever arm of variable length, the member which directly engages the pointer arbor is associated with an element suspended through flexible tapes from, and guided by, the pendulum drums. The load applied to a rod 22, Fig. 1, actuates the pendulums 13, 14 by means of a yoke 21, flexible tapes 19, 20, cams 15, 16 and drums 9, 10 suspended as usual from the frame 1 by tapes 5, 6. The pointer arbor 2 is actuated from the drums 9, 10 by means of a rack 29, tapes 23, 24 and a flat bar 27 disposed between. and guided by, the drums. In a modification, Fig. 2, instead of employing a bar between the drums, a frame 27 embracing the drums is used, and the rack 29 is hinged to the frame so as to exert a small gravity pressure on the pointer pinion 30. Under slight out-of-level conditions of the machine, the consequential differential pull of the tapes 23, 24 maintains a substantially constant pressure of the rack against the pinion. The pointer arbor 2, instead of being rotated by a rack may be rotated by a flexible steel tape.

Abstract: 1,070,848. S.C.R. switching circuits. W. B. ZELINA, and J. L. BUCHANAN. Aug. 14, 1964 [Aug. 14, 1963], No. 33215/64. Heading H3T. [Also in Division G3] A D.C. generator GEN operates to selfexcite its field FLD through a controlled rectifier SCR1 which is controlled to keep the output voltage at a pre-determined value. The control circuit for rectifier SCR1 includes a capacitor C1, a second controlled rectifier SCR2, a voltage divider R1, VR, R9, R5 connected across the generator output lines 11, 12, Zener diodes ZD1, ZD2, and a transistor TT1. The arrangement is such that when SCR1 is conductive capacitor C1 charges over resistor R3; when the voltage across C1 reaches a sufficient level, Zener diode ZD2 breaks down and current flows into the gate of SCR2 which is thus rendered conductive so that C1 discharges into SCR1 to turn the latter off. The rectifier SCR1 then switches on again if the output voltage is below the required level; otherwise it remains off since its gate voltage is cut off by the action of transistor TT1, which is rendered conductive when the voltage derived from the voltage divider R1, VR, R9, R5 exceeds the Zener voltage of ZD1. The field current of the generator is thus automatically regulated in a manner that maintains the output voltage at a constant value. A capacitor C2 provides for system transient protection, and rectifier SCR1 and SCR2 are protected against voltage transients by C6, R12 and C7, R11 respectively. A Shockley diode may replace the Zener diode ZD2 (Figs. 4 and 5, not shown).
