Abstract: 271,374. National Malleable & Steel Castings Co., (Assignees of Robinson, D., and Wittmer, R. J.). Aug. 5, 1926, [Convention date]. Couplings, automatic.-In a rigid jawed coupling having a buffing jaw 3, Fig. 4 ,and a pulling jaw 4 and a lock 7 adapted to reciprocate in a cavity 5 in the head of the coupling as shown in Specification 9622/12, lock-set mechanism 9 is suspended in the cavity and is adapted to engage and support the lock in elevated position for lock setting. The lock-set member 9 is supported in the head by a pin 11 and is provided with a projection 9<a> which, in the lock-set position. Fig. 3, .engages in a recess 21 of the lock when the latter has been pulled back by the bell-crank lever 8 pivoted in an elongated slot 14 of the lock. The end 8<b> of the bell-crank 8, in the looked position of the coupling, lies in front of a stop 17 projecting from the floor of the cavity and limits the distance the lock may be pushed rearwardly and prevents the lock from reaching lock-set position. The lock is provided with projections 15, 15a which abut stops 16 16a respectively in the coupling head to prevent the lock sliding out of the cavity. In lock setting from the coupled position the lever 8a is pulled rearwardly to rotate the end 8<b> clear of.the stop 17 and to move the lock rearwardly so that a projection 20 on the lock strikes the projection 9<a> on the lock-set member to raise the latter vertically until the stop 9<a> drops down into the recess 21 behind the projection 20. In this position the front portion of the lock-set member 9 abuts either the lock or part of the head of the opposing coupler and maintains the projection 9<a> in the recess 21. On separation of the couplings, the weight of the lock rotates the member 9 upwardly and releases stop 9<a> from its recess 21. Should the lock of one of a pair of locked coupling heads be moved into lock-set position it may be released from that position by a forward pressure on the projection 9<b> of the lock-set member 9.

Patent GB-580101-A (GB)
Title: Apparatus for investigating surface roughness
IPC: G01B7/34
Filed: 1944-02-25
Abstract: 580,101. Gauging surface roughness. BRUSH DEVELOPMENT CO. Feb. 25, 1944, No. 3540. Convention date, Feb. 26, 1943. [Class 106 (ii)] Apparatus employing an electrical pick-up measures the percentage of a surface in which the roughness exceeds a particular value. The peaks of the amplified pick-up wave are limited at a certain value and constant amplitude signals are then produced for times corresponding to the periods of limitation. The signals are then integrated with respect to time to provide the required percentage. The pick-up comprises a pivoted arm 22 carrying a large stylus 20 and a stylus 21 connected to a piezoelectric crystal 23 and provided with a sharp point to follow small scratches. The voltage output from the crystal is fed to an amplifier 28 with a push-pull output which is passed through rectifiers 33, 34 and a buffer amplifier 27 to a limiter 28. A bias battery 35 is arranged across a potentiometer 36 in series with a load resistance 37 in the rectifier circuits. The potentiometer is adjusted so that current is only transmitted by the rectifiers when a particular value of the roughness is exceeded. The limiter sends unidirectional pulses to charge the condenser 49 whenever the rectifiers are passing current so that the voltage indicated on the vacuum tube voltmeter 29 is a measure of the time, and hence the percentage of surface covered, in which the roughness is excessive. The length of time during which the voltmeter is responsive to signals from the crystal is controlled by a timing device 45. Calibration of the circuit comprising limiter 28, resistance 44. condenser 49 and voltmeter 29 is effected bv setting the potentiometer 36 for zero bias and then adjusting the condenser so that continuous signals transmitted by a device 39 will produce a 100 per cent reading in voltmeter 29. The potentiometer is graduated so that it can be set to a required reading in microinches. The Specification of the crystal being known, the signalling device is adjusted to give a suitable sinusoidal output and the resistance 54 is then adjusted until the voltmeter reading agrees with thevalue calculated in accordance with the potentiometer setting. If it is desired to have separate readings for peaks and scratches separate bias controls are provided for each rectifier and either switch 51 or switch 50 is opened so that one rectifier only is in circuit. The timing device may be omitted and replaced by a leak resistance in parallel with the condenser 49. A sine wave voltage will then produce a steady reading and an irregular wave surface will produce a fluctuating reading. In a further modification, the limiter is connected to an A.C. voltmeter having considerable inertia and damping.
