Title: Gyroscopic apparatus
Inventor: SEDGFIELD HUGH BROUGHAM
IPC: G01C19/38
Filed: 1956-03-26
Abstract: 854,507. Gyroscopic apparatus. SPERRY GYROSCOPE CO. Ltd. March 28, 1957 [March 29, 1956], No. 10041/56. Drawings to Specification. Class 97(3) [Also in Group XXXIV] In a gyroscopic apparatus, the rotor is enclosed in a case which is gimbal supported inside a mercury filled chamber. The bearings between the chamber and gimbal are of the fluid flow type, the mercury being forced through them, by an electrodynamic mercury pump into the chamber. Two embodiments are described in which the bearings are conical and spherical respectively. An expansion chamber allows for differences in the thermal expansion of the mercury and solid members. In both embodiments, a constriction is incorporated in the mercury flow path whereby the mercury pressure between the bearing and seating surfaces is reduced to half of the supply pressure when the surfaces are centralised. With the conical bearings, relative movement of the chamber and gimbal to restrict the flow of mercury between bearing and seating at one bearing causes an increase of mercury pressure at that bearing and a corresponding reduction at the other so that the gimbal is centralised by the resultant hydraulic thrust. With the spherica bearings, each is separately centralised in its own seating; one of the bearings is secured to and determines the location of the gimbal relative to the chamber, and the gimbal spindle at the second bearing is slidable therein. Specifications 854,506 and 854,508 are referred to.

Title: Blind fastener with expandable ring
Inventor: MCKAY THOMAS LORNE
IPC: F16B19/10
Filed: 1971-04-20
Abstract: 1279957 Anchored nuts; rivets T L McKAY 20 April 1971 [14 May 1970] 10212/71 Heading F2H A blind fastener comprising a sleeve 30, having a body portion 36 joined by a neck portion 40 of smaller outside diameter to a nut portion 38 with an internal screw-thread 48, and an expandable ring 32 embracing the neck portion, is inserted into a bore 35 of a workpiece 34 so that the ring 32 and nut portion 38 extend out of the far end of the bore, and the sleeve is contracted axially by tightening a bolt 52 therein to buckle the neck portion 40 so that it bulges outwardly as at 55 to expand the ring 32 and press it against the rear face of the workpiece 34. As shown, the body portion 36 has a serrated head 42 of larger diameter than the bore 35 so that when it is driven into the bore the sleeve is held against rotation. The neck portion 40 has at least two sections 40a, 40b of different diameters. In modifications (Figs. 25, 26, not shown) the neck has an annular rib between the two sections, forming a tapered shoulder to facilitate expansion of the ring. The ring 32 is a resilient split ring (Fig. 2, not shown) or two half-rings (60) (Figs. 9, 10, not shown) each having a plain end (62) and a stepped end (64) and extending over rather more than 180 degrees so that they can grip the neck portion with the stepped ends overlapping each other. The serrated head 42 may engage in a soft ring (75) of lead, copper, or aluminium in a counter-bore (74) of the workpiece bore (Figs. 13, 14, not shown). The head may be without serrations, and have a long tapered portion leading to the main body portion of the sleeve (Fig. 11, not shown), or an enlargement equivalent to the head may be formed on the body portion near the neck portion (Fig. 12, not shown). The bolt 52 may be removed after securing the fastener, the latter continuing to hold the portions of the workpiece together, though the bolt would normally be retained for strength. The bolt may have a countersunk head, with the bore 35 and the rear end of the sleeve suitably countersunk to receive it (Fig. 15, not shown). The whole body portion of the sleeve may be tapered externally, to be forced into a tapered bore so that it is frictionally held against rotation (Fig. 27, not shown). The leading end of the nut portion may be forced into a die to reduce its external and internal diameter to form a locking nut (Figs. 16-21, not shown). For thin workpieces, the body portion of the sleeve may consist solely of the head section. Such a modified fastener can be used with thicker workpieces in conjunction with a plain auxiliary sleeve 110, Fig. 24.
