Title: Hydraulically operated ram - has main rod with bore accommodating rotary auxiliary rod with spiral grooves and ramps
IPC: F15B9/10
Filed: 1974-11-29
Abstract: The ram comprises a piston (4) sliding in a cylinder (1) and solidly secured to a main rod (7) passing through one end wall (2) and having an internal bore (11).

Title: Pipelines reinforced by wrapping with steel strips - has wrapping tension equalised to avoid pipe distortion by simultaneous winding of two spaced sections
Inventor: DENOOR GASTON
IPC: B65H81/08
Filed: 1975-10-14
Abstract: Several strips, or wires, are wrapped round a long cylindrical body, such as, a pipe. The winding is simultaneously undertaken in opposite directions in two spaced zones. Thus, at least two strips or wires, are wrapped in each zone, so that the resulting tension forces are zero. In each zone, the strips, or wires, are pref. applied in pairs at diametrically opposed locations, the two wires in each pair being exposed to the same tension. The wrapping can be carried out on site, e.g. immersed pipes can be butt welded together on a pontoon and then wrapped continuously. Due to the balanced tension forces, the risk of pipe distortion during wrapping is eliminated and it is no longer necessary to hold the pipes in a jig.

Title: Interior car mirror windscreen fixing - uses enamelled patch fired into glass surface for attachment or mirror adhesive
Inventor: ROSELLI SERGIO
IPC: B60R1/04
Filed: 1976-01-22
Abstract: The inside of the windscreen is fitted with a patch of enamel which is applied before the glass is moulded into shape and which is fired into the glass surface by the subsequent heat treatment.
