Patent GB-2123479-A (GB)
Title: Ball-and-socket joint
Inventor: KANEKO SHINJI
IPC: F16C11/06
Filed: 1983-07-13
Abstract: A ball-and-socket joint, e.g. for a gas spring, has a socket 20 for receiving a spherical ball 25 of a ball stud which is mounted onto a member, where the ball is free to undergo rotary displacement within the socket. The socket comprises a main socket body 21 provided with a penetrating hole 26, a ring spring 23 having a discontinuous part, and a cap 22. The cap has a cylindrical part 34 which is formed with a space at an inner periphery thereof into which the ball is inserted, and an external screw 32 for engaging with a screw thread 29 of a large diameter part 30 of the hole 26 in the main socket body. The cap is screwed into the main socket body with the ring spring positioned in correspondence with a tapered part 31 of the penetrating hole. The end of the cylindrical part 34 pushes the ring spring 23 against the tapered part 31 when the cap is screwed in, and prevents the diameter of the ring spring from being enlarged, so that the ball inserted within the cylindrical part is prevented by the spring from slipping out of the cylindrical part. When the cap is unscrewed, the diameter of the ring spring can be enlarged so that the ball is free to slip in and out of the main socket body by passing through the ring spring. <IMAGE>

Title: Sealing a substrate using a recoverable sleeve
Inventor: MOLINARI ROBERT JAMES
IPC: B29C63/42
Filed: 1983-09-28
Abstract: Pipes (5) and other substrates exposed to or submerged in water can be protected by coating them with a corrosion protection sealing material and subjecting the material during or after it has been applied to the substrate to pressure applied progressively. The pressure is provided by progressive recovery of a sleeve as it is released from a holdout (1) which holds it in a recoverable configuration. The progressive recovery can be, for example, from one end of the sleeve to the other or from the center of the sleeve outwards to each end. The progressive shrinkage can be achieved, for example, by use of an external holdout which releases an inner expanded sleeve when contacted with solvent around the circumference of the sleeve commencing at one end of the sleeve and continuing along the sleeve to the other end. <IMAGE>

Patent GB-2147704-A (GB)
Title: Process for testing non-homogeneous building materials
Inventor: HERLT MANFRED
IPC: G01N3/56
Filed: 1984-09-17
Abstract: A process is provided enabling the compressive strength of non-homogeneous building materials, mainly concrete, and constructional elements made therefrom, to be non-destructively tested in the built-in state and at the manufacturing stage respectively. A current of hard particles of a size smaller than the largest grain of aggregate in the specimen is directed onto the specimen at a speed such that the kinetic energy of the particles is just sufficient to destroy that component of the over-all system which has the lowest individual strength and which is thus decisive for the compressive strength of the system as a whole. It is essential to the process that the current of particles acting on the specimen should move around the wear-resisting component and eject it after the cohesive combination has been re-separated. The compressive strength of the building material is determined from the change thus brought about in the geometry of the sample, taking into account the conditions under which the process has been carried out. The volume, depth or diameter of the crater produced in test cubes made of the building materials are used to provide calibration diagrams to enable the compressive strength of building materials to be determined.
