IPC: F16B21/16
Filed: 1959-12-08
Abstract: 929,946. Stud-and-socket fastenings; cotters. AERPAT A.G. Dec. 8, 1959 [Dec. 8, 1958], No. 41628/59. Classes 44 and 89 (2). A double-acting release pin assembly for clamping apertured work members 18, comprises a tubular shank member 10 having a central axial bore 12 and having side apertures 16 communicating with the bore, a plunger 20 mounted for movement axially within the bore, a ball 17 mounted in each of the apertures and adapted to be contacted by a portion 23 of the plunger for movement beyond the outer surface 11 of the shank member, the plunger having axially spaced grooves 21, 22 on opposite sides of the portion 23, a floating washer 32 encircling a portion of the plunger and mounted for axial movement within the shank member, a spring 33 acting to move the floating washer in one direction, a shoulder 15 on the shank member limiting motion of the washer in that direction, a shoulder 36 on the plunger engageable with the washer to move the latter in the opposite direction against the spring loading, and a second spring 34 interposed between the washer and a collar 35 fixed on the plunger acting to oppose axial movement of the plunger in the one direction. The shank member 10 has a portion 13 counterbored at 14 in which are disposed the springs 33, 34, the washer 32 and the collar 35, and the plunger 20 has a hexagonal part 26 projecting through a hexagonal opening 27 in an abutment ring 28, the latter being held in place against a shoulder 29 in the portion 13 by a rolled over lip 30 of the portion 13. The balls 17 are prevented from moving completely out of the apertures 16 by a reduction in size of the outer ends of the apertures. In operation, the assembly is inserted into the aligned apertures in the work members 18 by pressure applied to a ring 39 loosely attached to the plunger 20; the pressure moves the plunger to the projected position against the action of the spring 34, Fig. 2 (not shown), allowing the balls 17 to move to their retracted position and permitting the shank member 10 to enter the apertures in the members 18. The assembly is removed from the latter apertures by a pull on the ring 39 which moves the plunger to its retracted position against the action of the spring 33, Fig. 3 (not shown); alternatively, a nose 24 on the plunger 20 may be depressed to move the plunger to its retracted position. Specification 554,307 is referred to.

Abstract: 922,219. Buffers and or drawgear. J. B. CURRY, and F. W. LLOYD. Dec. 23, 1959 [Dec. 24, 1958], No. 41672/58. Class 103(5). A buffer arrangement which may be modified for use as drawgear or combined buffer and drawgear comprises a rubber or helical spring 4, Fig. 1, operating at first in series with a metal ring or split-ring column of springs 5 contained by a slidable auxiliary cylinder 6 provided with stops 10 for the plunger 2. When the plunger 2 abuts the stops 10 however the spring 4 will no longer be compressed, and further buffing movement will be resisted by the spring 5 alone. In another embodiment, Fig. 3, a rod 8 moving with the plunger 2 slides within a movable guide 18. The springs in this case first operate in series until the plunger 2 contacts the stops 10, then the spring 5 is alone compressed until the guide 18 contacts the base 12. Still further movement then compresses the springs 4 and 5 in parallel up to the limit where the stops 10 contact the base 12. In Fig. 2 (not shown) the rear end of the spring 5 fits over and is located by a hollow spigot flanged rearwardly to the size of the inner diameter of the cylinder 1, and a cushioning rubber pad is provided between the flange and the base 12. In drawgear in Fig. 5 (not shown) the column or rubber springs 4 is replaced by a set of rubber pads 4<SP>1</SP>, the casing 1 is stationary, and a movable casing 2 is connected by means of a yoke 20 to a drawhook 19.

Filed: 1971-09-14
Abstract: 1313231 Pyrometers ALNOR INSTRUMENT CO 14 Sept 1971 [14 June 1971] 42851/71 Heading G4H In a digital pyrometer, in which analogue voltage signals from a thermocouple 68 (Fig. 1) are digitized by counting output pulses from a dual ramp digital voltmeter in a binary coded decimal counter 20, certain output pulses are suppressed by a linearizer 16 so that the displayed count is linearly related to temperature. As described, the unknown analogue input is applied via a switch 64 through an integrator 78 until counter 20 has counted a predetermined number of pulses from a clock 12 after which bi-stable 42 is reset and a reference signal of opposite polarity, and derived, e.g., from a Zener diode circuit, is applied via switch 62 to the integrator. When the integrator output becomes zero a gate 52 is enabled to transfer the contents of counter 20 via latches and decoder to number tubes 34. If the counter overflows during the application of the reference signal a "thousand" lamp 48 is enabled. Suppression of selected pulses is effected by gates in the linearizer 16 responsive to a predetermined count in the counter. To enable fast switching of bi-stable 42 when the integrator output becomes zero the gate of a unijunction element (90, Fig. 4, not shown) is forced sufficiently below its anode to effectively short-circuit the element to ground so that a capacitor 94 is rapidly charged to set the bi-stable. Spools 72 and 74 provide compensation at low temperature and an offset voltage.
