[Also in Groups XXXV and XL (c)] Different modulating signals 11, 12 are applied through isolating resistors 24, 29 to a rectifier bridge 34-37 with opposite rectifier pairs 34, 35 and 36, 37 rendered conductive and blocked by a carrier wave 15 applied as shown to the bridge so that alternately each modulating signal is short-circuited to earth and the other applied to earth via a carrier resonant circuit 25, 30 common to both inputs. The input carrier wave has thus opposite halfcycles modulated by the different signals. In a modification the bridge is replaced by a single pair of oppositely connected rectifiers, with junction connected to earth, and the switching carrier applied through isolating resistors to the junction of the rectifiers with the resistors 24, 29. The R.C. circuits 22, 23 and 27, 28 provide amplitude and rate components of the signals.

Title: Means for regulating the speed of a driven shaft
IPC: H02P29/00
Filed: 1961-12-05
Abstract: 967,558. Automatic speed control. NECCHI S. p. A. Dec. 5, 1961 [Jan. 13, 1961], No. 43447/61. Heading G3R. [Also in Division F2] In a control system for regulating the speed of a shaft driven through an electromagnetic clutch, the output voltage of a tacho-generator associated with the shaft is applied to the magnetising winding of an electromagnetic brake acting on the shaft whereby the braking effect is varied as the speed varies so that the shaft speed is maintained constant. As shown, an A.C. motor 1 drives a shaft 3 through an electromagnetic clutch 4 the magnetising winding of which is connected, over a contact d of switch 14, to a voltage derived from a rectifier 9 fed from the motor supply circuit. The shaft 3 drives a load 5 and a tacho-generator 19 the output voltage of which is applied, over contacts d<SP>1</SP> and d<SP>11</SP> of switches 17 and 18, to the magnetising winding of a brake 16 acting on the shaft 3. In operation, the shaft 3 is driven so that there is some slip in the clutch 4; if the load 5 then increases, the speed of shaft 3 tends to decrease so that the output voltage of generator 19 and excitation of brake 16 also decrease whereby the shaft speed tends to remain constant. Conversely, the braking effect increases with decrease in load. An amplifier, e.g. a transistor amplifier, may be included in the electrical connection between the generator 19 and the brake 16 (Figs. 2 and 3, not shown). The switches 14, 17 and 18 are provided with other contacts a, a<SP>1</SP>, a<SP>11</SP>, b, b<SP>1</SP>, b<SP>11</SP>, and c, c<SP>1</SP>, c<SP>11</SP>, so that the shaft can be driven with no slip in the clutch and with the brake de-energized, can be stopped by the brake with the clutch de-energized, or can be free with both clutch and brake de-energized. Specification 927,630 is referred to.

The die of a pressure die-casting machine has an air vent 90, preferably connected to a vacuum line 104 and closable by an hydraulic piston rod 92 controlled by an electrically operated hydraulic control valve 178. A finger 150 on the injection piston rod 36 actuates a switch 146 at the end of the stroke of the injection piston to actuate the valve 178 and cause the piston rod 92 to close the vent to prevent passage of molten metal past it. Actuation of the switch also causes the valve 102 in the vacuum line to close, opening being effected upon closing of the dies. The melt is drawn into the shot chamber via an intake tube 16 which dips below the surface of the melt in the reservoir 10 and has a small inlet 20 to meter the flow. A cavity 96 in the die traps any molten metal which reaches the valve 92 before it closes.
