Title: Corrugated tubing
IPC: F16L9/06
Filed: 1969-08-28
Abstract: 1,209,569. Corrugated tubing. KOPPY TOOL CORP. 28 Aug., 1969 [11 June, 1969], No. 42852/69. Heading F2P. Corrugated tubing suitable for impact absorbing columns, e.g. a vehicle steering column, comprises a tubular member having an annularly corrugated surface for at least a portion of its length, in which either the root 16 or peak 14 portions are provided respectively with longitudinal annularly spaced bulges 18 or depressions (30, Fig. 6, not shown) connecting adjacent corrugation side walls 17. The number and size of bulges 18 or depressions (30), and the thickness or depth of the corrugations may vary along the longitudinal axis, to predetermine the collapse load characteristics of each corrugation, and the order in which they will collapse when subjected to such load. The embodiment shown, produced by moulding, has four equally annularly spaced ribs or bulges 18 crossing corrugation roots 16, except for root 16a, where the ribs are omitted to weaken the corrugation, and root 16b, which is strengthened by eight ribs. Peak 20 has a smaller diameter than the remaining peaks 14, thereby reducing the inclination of the adjacent corrugation walls to the longitudinal axis, and thus increasing the collapse load in that region. Roots 21 have a smaller diameter than the remainder, thereby increasing the inclination of the adjacent corrugation walls, and thus reducing the collapse load. Unequal annular spacing of the ribs 18 or (30) may be used to cause the tube to bend in a predetermined manner when subject to a collapse load.

Abstract: 1375086 Valves GAZ DE FRANCE 20 Sept 1972 [21 Sept 1971] 43622/72 Heading F2V A safety valve for mounting on a vertically disposed pipe comprises a valve seat 18 and a pivoted flap 17 which is retained against the closing action of a counterweight 40 by means of a piston 52 subjected to fluid pressure in a chamber 53. When the pressure is reduced, the flap closes automatically. The piston acts on one end 47 of a pivoted stirrup 30, which, at its other end, is pivotally connected to the flap and to the counterweight. In the closed position of. the valve, fluid can leak through passages 62, 60, 61 in the flap to equalize small pressure differences and thereby enable the flap to be readily re-opened by re-pressurizing the chamber 53. For large pressure differentials, however, a ball 63 closes the leak passages, and, to equalize the pressure on each side of the flap, it is necessary to insert a tool down a tube 11 to open a valve 56. The valve is contained in a housing 12 which can be screwed on to the vertically disposed pipe. In another embodiment, Fig. 8, the flap 117 is retained on its seat by a spring 80 acting on the stirrup 30. A pin 74 extending from a spring-loaded arm 70 closes a pressure equalizing port 76. Downward movement of the end 50 of a piston first causes the pressure equalization port 76 to open and thereafter the flap 117.
