Title: Circuit arrangements for measuring electrical energy
IPC: D01G15/00
Filed: 1973-05-25
Abstract: 1372978 Measuring electrical energy LANDIS & GYR AG 25 May 1973 [7 June 1972] 25061/73 Heading G1U Apparatus for measuring electrical energy (v x i) comprises two modulators 1, 2 for forming respective pulse trains wherein the ratio of the difference to the sum of mark duration and space duration is proportional to an input voltage and current respectively a coincidence circuit 5 which is preferably an AND gate for providing an output indicative of coincidence between the pulses of the two trains, a clock pulse source 10 which is coupled to a counter 13 via a second gate 8 such that the counter counts the clock pulses in dependence on the output of the circuit 5, and a symmetrical, rectangular pulse generator 15 which periodically reverses the polarity of one of the input signals and simultaneously reverses the direction or count at 13. The period of the generator 15 is much greater than that of the modulators 1, 2, and the counter 13 is arranged to count the clock pulses when coincidence between pulses of the trains is detected. The theory is explained in the Specification and it is shown that if the mark duration of the two modulators 1, 2 is respectively: T 1 /2 + K 1 v; T 2 /2 + K 2 i, where T 1 , T 2  are the periods of the modulators, k 1 , k 2  are constants, then the time averaged frequency of pulses reaching the counter is f r Àk 1 Àk 2 vi/T 1 ÀT 2  where #r is the frequency of the source 10 and v, i are time-averaged values. The reversals controlled at 15 nullify the effects of asymmetry in the outputs at 1, 2. In a modification, Fig.2 (not shown) the gate 5 is an EX-OR which responds to coincidence of both pulses and gaps and gate 8 is replaced by an EX-OR (19). During the first ¢-cycle of the generator 15, which provides an input to gate (19), pulses from the source 10 are counted into counter 13 when a state of coincidence exists, and are counted out otherwise. In the second ¢-cycle, the situation is reversed.

A metal extrusion press has a rotary carrier 30 for at least one billet container 32, 33 and at least one discard shearing punch 34, 35 whereby rotation of the carrier will bring the container and shearing punch alternately into the press axis. Two containers and two punches are provided for alternate use on the carrier 30 which is rotated by a motor 36 through gearing 38 and can be moved axially by an hydraulic motor 52. Two alternately acting dies such as 49 are arranged on a second carrier 40 rotatable through gearing 46 by another motor 44, Fig. 3 (not shown), and movable axially by an hydraulic motor 54, Fig. 2 (not shown). The press is used for extruding tubes and its stem 14 carrying a dummy block 15, Fig. 2 (not shown), is actuated by a main ram 12; a mandrel passes axially through the stem. After extrusion the carrier 30 is retracted and then rotated to bring a shearing punch 34 into the press axis. The punch is pressed forwardly by the press stem 14 to shear off the discard against the die. The carrier 30 is then rotated through 90 degrees to bring the next billet container 32, which has been charged with a billet by means 58, into the press axis. Simultaneously the carrier 40 is rotated through 180 degrees to bring the new die 49 into the extrusion position. A container brushing means 56 is provided. The discard may alternatively be severed by a pendulum saw 60 which can also move parallel to the press axis.
