Title: Improvements in and relating to journal bearings, axle boxes and the like
IPC: B61F17/36
Filed: 1926-04-15
Abstract: 258,504. McLintock, J. April 15, 1926. Force-feed lubricating.-A holder e for a block d of solid lubricant which is pressed against the underside of an axle or shaft b by a spring f<1> acting on a plate f is secured on a resilient supporting plate g disposed within an inclined recess i in the bottom of the axle-box or bearing casing. The outer end g<2> of the plate g is bent as shown so that the plate lies horizontal, while the inner end g<1> is bent up to abut against a projection g<3>. The holder e is guided by ribs j, and the plate f has studs f<2> engaging slots e<1> in the holder. Guide pins j<1> secured to the plate g extend through the block d and bear on the axle. A thrust bearing comprising a convex head m bearing against the concave end of the axis and secured on a tubular member l screwed in the end cover h of the axlebox is lubricated by a block o of solid lubricant located within the member ! and pressed forward by a disc q acted on by a. spring p abutting against a plug n screwed into the inner end of the member l, the lubricant passing to the bearing surface through a passage m<1> in the head m. The amount of lubricant in the member l can be ascertained by unscrewing a pin r, which is screwed in the plug n and passes through the block o, until its screwed end is clear of the plug, and then partly withdrawing it. A sudden decrease in the resistance to such movement indicates that the inner end of the pin is free from the block o, so that the amount the pin is withdrawn indicates the amount of lubricant in the member.

Title: Control circuit
Inventor: NEWMAN REGINALD WILLIAM
IPC: H02P7/00
Filed: 1964-03-09
Abstract: 1,078,031. Automatic control systems. BRITISH ELECTRIC RESISTANCE CO. Ltd. March 9, 1965 [March 9, 1964], No.9923/64. Heading G3R. A control system for a reversible electromechanical drive device 9 includes thyristors 4 and 5 which are biased to define a dead band, both thyristors remaining non-conductive so long as an error signal applied to the system is within the dead band. When the error signal falls outside the dead band, one thyristor is rendered conductive; the resulting current flow actuates device 9 to reduce the error, and at the same time changes the bias applied to the thyristors so that the dead band is temporarily widened. As shown, the bias voltages for the thyristors are derived from amplifiers 12, 13 having output terminals 18, 17; if an error signal causes one thyristor, e. g. thyristor 4, to conduct, the resulting current flow through a variable resistor 11 produces a voltage to charge a capacitor 10. The voltage at junction 16 between the capacitor 10 and resistor 11 is thus driven negative whereby the outputs from the amplifiers 12, 13 which are also connected to the point 16, are changed to vary the bias on thyristors 4, 5 in a sense to widen the dead band. After some correction of the error has taken place thyristor 4 ceases to conduct, the current in device 9 ceases, the capacitor 10 discharges through the amplifiers 12, 13 and the dead band contracts to its normal value. If the residual error is outside this normal value the device 9 is re-energized and the cycle repeated to give a finer correction. It is stated that this arrangement prevents overshoot, particularly when applied to the positional control of motors. The system may include a diode 19 connected between capacitor 10 and resistor 11. An embodiment suitable for the control of an automatic voltage regulator, in which the device 9 is a reversible motor driving the brush gear of a variable voltage transformer, is described with reference to Fig. 4 (not shown).

Title: Output circuit arranged to output stage of semiconductor circuit
Inventor: KOIZUMI MASAYUKI
IPC: H03K17/687
Filed: 1992-01-09
Abstract: PURPOSE:To provide the output circuit immune to a switching noise and operated at a high speed. CONSTITUTION:Latch control circuits 32, 33 in the steady-state of an input signal control the operation of latch circuits 22, 23 to latch an output signal level. On the other hand, a drive control circuit 31 controls drive circuits 12, 13 in the transition of an input signal to allow voltages VDD1, GND1 to fluctuate. However, voltages VDD2, GND2 fed to the latch circuits are not fluctuated. When the input signal reaches a steady-state, the latch control circuits 32, 33 control the operation of the latch circuits 22, 23 to apply the voltage VDD2 or GND2 to a load. Since the load is charged/discharged already by the drive circuits 12, 13, the voltage VDD2 or GND2 is not fluctuated. Thus, output circuits in the steady-state arranged side by side are free from the effect of noise by other output circuit in the transition state.
