Title: Assembly machine for cable sheath sections - has automatic bonding agent applicator positioned between sheath end jaw assemblies
IPC: B29C65/52
Filed: 1975-12-17
Abstract: The sections of synthetic material sleeving may be of order 6 metres long and have a male end (24) and a female end (22). A base supports two sets of jaws one (14, 16) clamping the female end and the other (28, 30) the male end. Between the two is a set of hollow jaws (38, 40) which contains the bonding agent which is forced out through the spreader brushes (46, 48) when axially mounted pistons (56, 58) are forced inwards. The piston movement is achieved automatically by arranging the jaws holding the male end to slide in grooves (34) in the base under the action of a hand lever (62). When the pipes have been positioned and the jaws closed, movement of the lever first causes the bonding agent to be applied to the male end and then draws the ends together to form the joint. A vertically sliding fork (74, 76) is fitted to raise the joint out of the jaws when finished.

Patent FR-2336617-A1 (FR)
Inventor: SHAKIB IRAJ D
IPC: F15C1/00
Filed: 1976-11-08
Abstract: In a system with pneumatic logic elements, the control valve, briefly triggered mechanically, transmits air-pressure impulses to the logic elements (46, 48). A plate-shaped valve body (34) is movable in the valve chamber (30) between two end positions, where it closes either the valve inlet (28) or a discharge port (38) connected to the atmosphere. The control valve is bistable in as much as the valve body (34), in the event of failure of the mechanical triggering, remains in the bottom end position despite the presence of a pressure impulse and closes the valve inlet (28) or, after triggering is effected, remains in the top end position and connects the valve inlet (28) to the valve outlet (42) via the valve chamber (30) as long as the pressure impulse is present at a sufficient level. The forces acting on the valve body in the end positions due to the pressure impulse differ in accordance with the area covered in each case of the bottom (32) or top (40) valve seat. Due to this bistable behaviour, the control valve is insensitive to interference impulses.
