Patent GB-2082205-A (GB)
Title: Dispersion-hardened platinum- group metal articles
IPC: C22C1/05
Filed: 1981-08-04
Abstract: Semi-finished articles of dispersion hardened platinum-group- metal alloys are made by co- precipitation of the precious metal together with one or more base metal oxides to give a fine powder mixture, sintering the mixture without prior compression in a two-step process at 700-1100 DEG C and 1300-1600 DEG C respectively, turning the agglomerate through 180 DEG  between the steps, optionally subjecting the base metal component to oxidation, and processing the agglomerate to the semi-finished article e.g. by forging. The sintering steps are preferably carried out under argon but may also be carried out in vacuo, or under air or H2. In an example, platinum containing 0.16% zirconium oxide is heated under argon for 8 hours at a temperature rising to 800 DEG C, then for 7 hours at a temperature rising to 1600 DEG C to give an agglomerate of 60% density, then forged at 1200 DEG C to 90% density before being cold rolled to sheet with intermediate anneals.

Patent GB-2100388-A (GB)
Title: Vibration damper
IPC: F16F15/16
Filed: 1982-06-03
Abstract: A vibration absorber for attachment to a vibrating component such as rotatable shaft 14 includes a fluid container 11 partially filled with fluid 12 which is urged outwardly during rotation. Inward reaction of the fluid results in resonant waves in the fluid which may be tuned to balance unwanted lateral radial vibration forces. The fluid is water. The absorber is particularly suitable for attachment to the rotor assembly of a helicopter to overcome the problem of the high rotor derived vibration levels transmitted to the fuselage of such aircraft. The resonant frequency of such an absorber varies with rotational speed and may be made self tuning over a range of rotor speeds. <IMAGE>

Patent GB-2125624-A (GB)
Title: Electrical switching apparatus
Inventor: WELCH ROBERT JOHN
IPC: H01H1/16
Filed: 1982-06-30
Abstract: An electrical switching contact (Figure 3), especially for an arcing contact of a tap changer switch, comprises a roller 31 rotatably mounted on a shaft 32. The shaft also has reaction means 36 between which and the roller a helical spring 35 extends coaxially with the shaft to bias the roller into electrical contact with a shoulder 34. The spring is a light frictional fit on the shaft and keyed at one end to the roller for rotation therewith. Attempted rotation of the roller in one direction winds the spring onto the shaft by increasing frictional pressure thereby preventing further rotation, while rotation in the opposite direction takes place freely. Alternatively, a spring 57 may be a light frictional fit both on a roller 51 and a sleeve 55, fitted on a shaft 52, and will also wind tight in one direction of roller movement to prevent further such movement (Figure 5). The spring 35 or 57 provides a simple method of providing both axial bias and ratchet effects. <IMAGE>
