Title: Device for launching and/or retrieving pipeline scrapers
IPC: F16L55/46
Filed: 1975-10-02
Abstract: 1517198 Launching/capturing pipeline pigs; pressure vessel closures WILLIS OIL TOOL CO 2 Oct 1975 [6 June 1975] 40425/75 Headings F2N and F2P A pipeline pig launcher or receiver includes a substantially spherical valve member 18, Fig. 3, formed with a through passage 80 having at one end a grid 84, which permits fluid flow but blocks passage of the pig (not shown), the valve member 18 being rotatable about axis 85 to bring the other end of passage 80 selectively into register with a pig magazine 25 and at least one of pipeline connection ports 20, 21, the valve member being housed in a cylindrical chamber 16, Fig. 2, to provide permanently open passages 141 between ports 20, 21. The valve member is urged towards an elastomeric valve seat 40 by stacks of spring washers 94, Fig. 2, acting through rings 92 and 86, so that in the position shown in Fig. 3 the pipeline is sealed from the magazine 25. A passage 34-38 connecting the pipeline and the magazine is controllable at 32. Pressure in the magazine may be relieved at 30. Rotation of the valve member is effected by hand wheel 102 acting through worm gearing (Fig. 4, not shown), shaft 115 and tongue 118, which engages with clearance in a slot 120 formed in the valve member. Pressure vessel closure.-The magazine 25 has a closure 26 rigidly mounted on arm 55 which is hinged at 58. A locking ring 48 for the closure is supported on rollers 68 for rotation about the magazine axis and is formed with a circumferential series of spaced helical projections 46 which, on rotating the ring, engage with corresponding projections 45 formed on the closure. The necessary rotation is imparted to the ring 48 by nuts and bolts 66, 65 which connect lugs 64 of the ring and lugs 62 of the closure. Disengagement of projections 45, 46 is positively prevented by fingers 78 (also Figs. 5 and 6, not shown), which extend downwardly between adjacent engaged pairs of projections and are carried by a plate 76 bolted to the cover at 74. Removal of bolt 74 relieves the pressure in the magazine if this has not already been effected at 30.

Abstract: 1282915 End-face seals F BURGMANN [trading as FEODOR BURGMANN JNR ASBEST-UND PACKUNGSWERK] 14 Aug 1969 [17 March 1969] 40582/69 Heading F2B A mechanical seal for a nuclear reactor pump comprises a pump device formed by external and internal screwthreads 15, 17 for circulating a cooling, lubricating or sealing medium to the sliding face, the screwthread rotatable with the shaft being of opposite hand to that of the screwthread associated with the shaft housing. As shown, a stationary seal ring 8a is urged by springs 14a into engagement with a seal ring 7b rotatable with the shaft, the carrier 3b for the rotary ring being provided with the external screwthread 15. The medium is discharged through an outlet 19 and passes through a heat exchanger before returning to an inlet 18. The face of either of the seal rings may be provided with arcuate grooves which extend from one point on the circumference to another. In a second embodiment, Fig. 2 (not shown), the ring (8b) rotatable with the shaft is spring- loaded towards the stationary ring (7a), the load being modified by the axial thrust generated by the pumping action. In a third embodiment Fig. 3 (not shown), two mechanical seals are' provided in series, the rotary seal rings (8<SP>1</SP>b' 8<SP>11</SP>b) of which are urged along the shaft in opposite directions towards the stationary rings and are surrounded by a single sleeve (23) containing the external screwthread (15); in this embodiment, the pressure of the medium is increased by means of a gas-charged container (22) in the circuit. In a fourth embodiment, Fig. 4 (not shown), two mechanical seals are provided and the carrier for each rotary ring is provided with an external screwthread. In a fifth embodiment, Fig. 5 (not shown), the spring for urging the rotary seal ring into engagement also serves as the external screwthread.

Title: Method of adhesively bonding foldable board
IPC: B31B5/74
Filed: 1958-12-31
Abstract: 862,930. Seaming non-metallic sheet materials. BALJAK CORPORATION. Dec. 31, 1958 [Jan. 7, 1958], No. 42193/58. Class 42 (1). [Also in Group XVII] A method of adhering areas of two surfaces of board face-to-face comprises first applying to at least one of the surfaces an aqueous emulsion of a thermoplastic adhesive, then heating the applied adhesive while on the board to a temperature sufficient to coalesce the adhesive component and convert it from its divided emulsion state of low tackiness into a state of high tackiness and then pressing the two surfaces together whereby an instantaneous contact type bond is formed. In the embodiment shown, a sealing and closing machine 11 comprises a top rail 31 which engages the initially upright cover panel 21 of the box 14 and folds it into the position shown in Fig. 2. In this position flaps 24, 25 and 26 are in a position to be folded down and sealed. As the box is advanced by conveyer 12 the box first passes through a heating and dewaxing section 17 where a heating unit 32 removes the wax from the two surfaces to be sealed. After the box leaves section 17 the front flap 26 is flattened out and passed over an adhesive applicator in the form of a wheel 42 which applies a film of adhesive to the underside of flap 26. Guide rails ensure proper contact between the flap 26 and wheel 42. The adhesive is essentially an aqueous emulsion of the consistency of heavy orlan, the adhesive constituent being a polyvinyl acetate resin. The flap 26 is engaged by a rail 51 which brings the flap into contact with the wall panel 30 as the box 14 advances. The roller 52 presses the flap 26 against wall 30. At this stage the adhesive has a rather low degree of tackiness which is insufficient to hold the flap down after the box moves beyond roller 52 so that the flap 26 swings away from the wall panel 30 but some of the adhesive has been transferred to the panel 30. The box next passes into a heating- section where the adhesive is brought to a high degree of tackiness. The heat is preferably applied by quartz lamps. The box then passes into a closing section (Fig. 8) where the flap 26 is guided by rail 56 against the wall panel 30. A series of resilient pressure rollers 57 press the flap 26 into firm contact with the wall. The process is repeated for the side flaps 24 and 25.
