Title: Improvements in or relating to static packing arrangements
IPC: F16J15/10
Filed: 1970-10-14
Abstract: 1287501 Pipe joints; joint-making packing FRANCE ARMED FORCES MINISTER OF 14 Oct 1970 [17 Oct 1969] 48911/70 Headings F2B and F2G A fluid-tight packing arrangement for highpressure pipe connections comprises a toroidal member 1 of elastomeric material and concentric annular members 4, 5 of thermoplastics material held within a further concentric annular member 8 of metal. As shown in Fig. 3 a pipe coupling comprises flanged sleeves 12, 13 mounted on pipe ends 6, 7 and bolted together, the bolts 15, 15a also serving to position the packing arrangement by contacting the metal collar 8. The collar 8 prevents extrusion of the plastics collars under high pressure. As shown in Fig. 2, the intermediate collar 4 is slightly thicker axially than the metal collar 8 and is retained within the collar 8 by overlaps 11, 11a around chamfered edges 9. Grooves 2, 3 are provided in the collars 4, 5 and are tangential to an arc of radius equal to the cross-sectional diameter of the packing toroid 1, which in turn is greater than the axial thickness of the collar 4. The elastomeric material of the toroid is thus compressed between the faces of the flanges 12, 13 into the grooves 2, 3 but extrusion of the toroid 1 under high fluid pressure is curbed by the opening of the flanks of the groove 2 in the collar 4 against the flange faces. The deformation of the groove flanks also permits a fluidtight pressure seal to be achieved even when the flange faces are not exactly parallel.

Title: Apparatus for measuring the thickness of a tube
Inventor: BREBANT CHARLES
IPC: G01B5/20
Filed: 1966-11-01
Abstract: 1,097,639. Determining dimensions. COMMISSARIAT A L'ENERGIE ATOMIQUE. Nov. 1, 1966 [Nov. 10, 1965], No. 48966/66. Heading G1M. An apparatus for measuring the thickness of a tube 81 comprises a tube carrier 6 Fig. 1 (not shown) for locking the tube in the measuring position and two feelers 9, 11 contacting the inner and outer surfaces respectively of the wall of the tube to be measured, each feeler being attached to one of the ends of a straight arm 8, 10 pivotally mounted on a carriage 12 moving in a direction parallel to the axis of the tube, which also has elements for restoring the arms to a position in which the feelers are brought towards one another and detectors for recording the distances between each arm and consequently each feeler. Means are also provided for moving the feelers apart to allow the tube to be positioned on the feelers. The carriage 12 is rigidly connected to a nut 14 driven translationally by rotating a screw 16 connected to a motor 20. Each feeler arm 8, 10 is mounted in a sleeve 8b or 10b which is pivoted to the carriage 12 at 34. Between the pivot 34 and a guide ring 30 these are provided springs which tend to separate the sleeves 8b, 10b and hence bring the feelers together. The feelers are moved apart by electromagnetics which pull the lower part of the sleeves together. The sleeves are in contact with the contact members of detectors 66 for the continuous recording of their movements. Toothed gearwheels 68, 70 are provided to record by means of contacts 72, 74 the axial distance covered by the feelers. The tube 81 is held in place by means of two sets of three rollers one of each set being adjustable. When the tube is in place and the feelers are moved up to the end of the tube the electromagnetics are excited to bring the feelers into contact with the tube and the motor started to raise the carriage to move the feelers along the tube.

Title: Improvements in fitments for loose leaf binders

Filed: 1965-11-18
Abstract: 1,103,353. Filing papers. C. J. BROADHURST. 5 Oct., 1966 [18 Nov., 1965], No. 49045/65. Heading B6E. Loose leaves with filing perforations are retained in a binder by a fitment 1 having a strip-like member 4 of resilient material which is curved about its longitudinal axis in the leafreceiving position shown, but when bent into ring-like form (Fig. 2) the member 4 straightens about its longitudinal axis to assist the bending, and is retained in the ring-like form. The fitment 1 is of pressed metal with lugs 2, 3 for securing it on the spine &c. of a binder, and has two strips 4 of metal or synthetic plastics material having an inherent spring bias secured thereto. The free ends of the strips 4 may be engaged in openings 6 in the fitment 1. In another construction (Figs. 3 and 4), the striplike members are riveted by central portions (7) to a mounting plate (8), to provide upstanding opposed leg portions (9, 10) which are curved about their vertical ones. The upper ends of the legs can then be bent over each other to assume a closed position over the filed leaves (Fig. 4), no retaining means being necessary. Opposed pairs of strip-like members (12, 13, Figs. 5 and 6) can be integral with a trough-like member (11) which may be secured to a binder, or may serve as the spine of a binder and have perforated loose covers filed over the strip-like members. In a further construction (Figs. 7 and 8), a single row of strip-like members (14) is arranged on a trough-like spine (16), and the opposed edge (17) of the spine may have slots therein to receive the free ends of the members (14) in the curved position.

Fig. 1, such as a power tool supported by an overhead carriage 14, 20 running on rails 36, comprises a parallelogram linkage system 12, 64, 68, 77 arranged with the lower generally horizontal member 64 rotatable on its axis XX in bearing 60 which is pivoted to the carriage on a horizontal axis ZZ and carries the loadsupporting member 77 on a pivoted axis YY at its end. The counterweight 74 is mounted above the XX axis and behind the ZZ axis relative to the load 81 so that a balance is maintained for movements of the load 81 about all three axes XX, YY, ZZ. The carriage 14, 20 may be driven by a motor 90 which is servo-controlled from a valve 84 actuated by sideways movements of the power tool 81 through a linkage 96, 98 when the member 64 rotates about the XX axis. In a modification the counterweight may comprise two parts 163, 169, Fig. 3 (not shown), one part 163 being fixedly mounted on a vertical member 162 for counterbalancing the system when unloaded, and the other part 169 for counterbalancing the power tool &c. being pivotable on an axis 161 so that it may be swung to an ineffective position. An hydraulic actuator 172 attached to the member 162 may be used to swing the weight 119 between the two positions. In a further modification the main support member 224, Fig. 12 (not shown), may be longitudinally adjustable in its bearing 220 as by screw nuts 246, 248 for adjusting the balance.
