IPC: F16H57/025
Filed: 1964-11-26
Abstract: 1,058,060. Toothed gearing. GETRIEBE. WERE GOTHA, VEB. Nov. 26, 1964, No. 48096/64. Heading F2Q. To prevent shocks and to equalize the torque transmitted through planet pinions 2b, the stationary ring gear 2c of a sun-ring planet train 2 is yieldably mounted in a housing 1 by lugs 3 thereon engaging recesses 7 in pistons 4, 5, the associated cylinders 8, 10 or 9, 11 of which, according to the direction of rotation of an input shaft 19, are supplied by a gear pump 16 with pressure fluid which opposes the reaction torque. A duct 6 through the piston 4 connects the cylinders 8, 9 through a one-way valve 21 to a vent 22 and tapered needles 12, 13 throttle the flow from the cylinders. An increase in the reaction torque moves the piston 4 axially, whereupon the throttling effect is increased and the pressure in the cylinder 8 or 9 opposing the reaction torque also increases. Hydro-pneumatic accumulators 14a, 15a absorb sudden pressure increases caused by rapid movement of the pistons 4, 5 in response to torque surges in the transmission and thus prevent shocks. The pump 16 is driven from an input shaft 19 fast with a sun gear 2a.

Title: Temperature linearization circuit
IPC: G05D23/24
Filed: 1969-10-10
Abstract: 1,271,125. Automatic temperature control systems. PERKIN-ELMER CORP. Oct. 10, 1969 [Oct. 11, 1968], No. 49850/69. Heading G3R. To compensate for temperature gradient existing between a heater 10, which is also used as a temperature sensor, and a spatially separated substance 14 which it is desired to heat in a determined manner by varying the set point voltage according to a programme, a portion of this voltage is applied to the heater, the resulting current from which is stated to linearise the relation between the sensed temperature of the heater and the true temperature of the substance. A heater 10 e.g. a platinum element having a substantially linear resistance/temperature characteristic has an A.C. heating current passed through it during a portion of a cycle while the resistance of the heater is sensed during another portion. A sensing current is derived from a D. C. source E1 through a resistor 24, the voltage across the heater being applied, together with a reference voltage from potentiometer 33, 28 through a chopper 46 and amplifiers 48, 50 to an amplitude to phase converter 52 which controls the firing point of the thyristor 18, and hence the current to the heater. The set point is derived from a motor driven potentiometer 34, 36, 38 and passed through amplifiers 40, 42 to potentiometer 33, 28. A potentiometer 64, 66 is connected across amplifier 42 hence a determined fraction of the set point voltage of appropriate polarity is applied through a resistor 69 to heater 10. A resistor 76 applies a balancing voltage to the other input of chopper 46. A biasing current is also applied through a variable resistor 72 so that the extended characteristic (e.g. 73) Fig. 3 (not shown) will pass through the origin of the co-ordinates, the slope of the characteristic being adjusted by resistor 33. As voltages of opposite sign are applied to the terminals of potentiometer 64, 66, adjustment of the slider 66 enables heaters constructed of say nickel having opposite characteristics to that of platinum and copper to be accommodated into the circuit. The circuit may be used in conjunction with a thermal gravimetric apparatus (not shown). The chopper 46 may be of the electro-mechanical or electronic type.
