Title: Improvements in or relating to apparatus for delineating electric pulse signals
IPC: H03K17/54
Filed: 1945-05-14
Abstract: 591,318. Cathode-ray oscillographs. SPERRY GYROSCOPE CO., Inc. May 14, 1945, No. 12120. Convention date, Jan 4, 1944. [Class 37] A pulse controls a time base generator for one component of movement of an oscillograph, and is applied over a delay circuit to control the other component of movement of the oscillograph so that the whole of the pulse is delineated on the screen. The pulse is applied at 4 to valve 2 and double diode 3 to produce a positive pulse for actuating a multi-vibrator constituted by pentodes 7, 8 whose screen grids act as anodes so that outputs can be taken from the plate circuits without affecting the multivibrator ; the pulse from valve 7 is applied to render the right-hand section of valve 17 non-conductive, thus allowing condensers 12, 13 to charge until the cessation of the pulse discharges the condensers through valve 17. The condenser potentials are amplified at 31 and applied to the deflecting plates of the cathode-ray tube 34. The original pulse is also applied over valve 36 and a delay network 37 to the other plates of the cathoderay tube. Marking pulses are developed from the output of valve 7 by an oscillator 44, shaping amplifier 46, differentiating circuit 51, 52 and limiting valve 54 and are applied to the control grid of the cathode-ray tube to produce bright spots on the base line. A pulse from valve 8 removes cut-off bias from the cathoderay tube during portrayal of the pulse. Specification 552,072 is referred to.

Title: A Polyphase Electricity Meter
IPC: G01R11/40
Filed: 1967-03-15
Abstract: 1,162,564. Electricity meters. SIEMENS A.G. March 15, 1967 [March 15, 1966], No. 12238/67. Heading G1Q. A member 2 of magnetic material is pivoted on or adjacent the voltage electromagnet of phase II of a three-phase electricity meter so that its free end can be moved between positions closer to one or the other of the voltage magnets of the other two phases I, III. By adjusting the position of this member, disturbing torques caused by interaction of the voltage fluxes of adjacent phases can be minimized. The disturbing torques, between phases I-II and II-III represented in Fig. 2 by the unbroken long arrows, should in theory balance, but in practice there is a residual error torque. The further disturbing torque, represented by the short unbroken arrow, between phase II and whichever of the other phases the free end of member 2 is closest to, can largely eliminate the error torque. In an assymmetric arrangement of the driving- magnet systems (such as the 90-90-180 degrees arrangement shown), it is the central driving- magnet system which should carry the member 2. This member is preferably cranked, as in Fig.4, so that it is more widely spaced from the rotor disc 1 at its pivoted end than at its free end. The member may be Y-shaped as in Fig. 5 (not shown), the 'leg' of the Y providing the pivoted end and the 'arms' the free end - each arm being directed generally towards a corresponding one of the voltage magnets of phases I and III. In this arrangement two opposing compensating torques, one larger than the other, are produced. The rotor disc, shown plain, may in fact be slotted, e.g. by a single circular slot.

Abstract: 793,334. Guiding webs transversely. DUNGLER J. April 24, 1956, No. 12458/56. Class 100(1) An apparatus for traversely guiding webs of the type having a pair of tiltable rollers 5, 6 engaging opposite selvedges of a travelling web and responsive to change the degree of tilt of the rollers upon lateral deviation of the web the rollers being mounted for movement toward and away from each other in a frame 2 pivotably mounted on a support 1, is characterized in that it further comprises a spring 13 urging the rollers together, means urging the frame 2 to a position in which the axes of the rollers assume an inclined position with respect to the marginal web portions, web tensioning means for tilting the frame, upon lateral deviation of the web against the action of the frame urging means, and means to move the rollers apart as the frame is tilted toward the position in which the axes of the rollers extend at right angles to the marginal web portions. As shown, a counterweight 17 urges the frame 2 into a position in which the axes of the rollers are substantially at right angles to the marginal web portions, while a web-engaging tensioning fork. 16 tilts the frame upon lateral deviation of the web towards the fork. Tilting the frame causes a cam follower 11, on the end of an arm 8 carrying the roller 6 to engage a cam 12 to rock the roller 6 away from the roller 5. The selvedge engaged between these rollers is thereby released and the transverse guiding effect of these rollers is interrupted. The web is restored to its correct path by an identical pair of rollers; not shown, engaging the opposite selvedge, which tilt to increase their guiding effect upon deviation of the web away from such rollers The roller 6 moves towards the roller 5 when the web is restored to its correct path.. In a modification, Fig. 4, not shown, the counterweight is replaced by a helical spring and the tensioning 'fork by a grooved wheel; in which case a cable, wound around the shaft of the wheel, is attached to the,frame to effect tilting there of. Alternatively, the cable may be replaced by a toothed rackco-operating with a toothed wheel on a shaft carrying the grooved wheel.
