Abstract: 947,564. Hinged doors. STATE OF ISRAEL. Aug. 27, 1962 [Aug. 28, 1961], No. 32847/62. Heading F2P. An emergency sealing device for sealing an aperture, such as an outlet in an atomic reactor, comprises a drop flap 1 having a substantially spherically faced rim 3 adapted sealingly to seat against a sealing ring 30 fixed around the aperture, flap support means, e.g. parallel arms 4, 5 mounted on a horizontal spindle 8, adapted to be pivotally mounted with respect to a support structure 11, and so coupled to the flap as to permit limited pivotal displacement of the flap with respect to the support means about a point located substantially at the spherical centre of the rim 1, means for releasably retaining the flap out of engagement with the ring, and means for retaining the flap in sealing engagement with the ring after the flap has been released so as to drop into said sealing engagement. As shown the arms 4, 5 are integral with a sleeve 6 surrounding a spindle 12 secured to the flap and housing a spring 16 disposed between a collar 13 secured to the sleeve and a collar 19 secured to the spindle, the collar 13 having a conical inner surface engaged by a spherically faced bearing 14 screwed on to the spindle; the collar 19 carries a resilient ring 20. The ring 30 is in two parts 30a, 30b clamped together by bolts 33 and retaining a sealing ring 32. The retaining device 21 includes a spring-loaded bar 23 which, when the flap has dropped, is turned through an angle of 90 degrees by contact of the arm 7 with the trip bar 27. A lever 34 secured to the spindle 8 is coupled to a shock-absorbing mechanism. The flap is held in a horizontal non-operative position by solenoid-operated lazy tongs which grip a pin secured to the flap. In a modification, the flap is attached to a curved arm the hinge spindle of which has secured thereto a lever supporting a drop weight comprising a sealed cylindrical container in which is disposed a weight formed with a central bore and supported within the container by a spring; when the flap is released, the drop weight falls and as the flap hits the seat thereof continues a downward movement against the effect of the spring, oil passing up the bore to displace a ball valve, and when the weight comes to rest the weight is returned to the initial position by the spring at a slow rate determined by the rate of return flow of oil around the sides of the weight. The lower end of the arm extends through a sleeve and is connected to the latter in a manner similar to that shown in Fig. 3, but the spring 16 is replaced by an annular, rubber plug.

A method of disintegrating argillaceous masses for the production of roof and wall tiles comprises subjecting the material to a coarse disintegration by rotating tools, pressing the material through a screening zone in a simultaneously rotating and axially progressing stream, and thereafter forcing the material in a radial direction through a sifting drum zone so as to be finely disintegrated. The coarse disintegration is carried out in a zone A of a combined coarse and fine disintegration apparatus, the zone A being fed with the material through a hopper A and having a plurality of crushing wheels 19 which are rotated by gearing 13 and a clutch 12 from a belt drive 11 and co-operate with a crushing grid comprising a number of bars 16 mounted on a pivot 17, the free ends 16a of the bars bearing against screws 18. The crushing wheels have arms 19a which are of spiral form and inclined so as to convey the coarsely disintegrated material through a screen 20 into a fine disintegrating zone B having a pair of fine disintegrating wheels 22 disposed within a sifting drum 23 and separated by a transverse screen 25. Each wheel 22 has a plurality of arms 22a carrying exchangeable spiral shoes 22b, the right-hand wheel also having vanes 26 to press some of the material through the screen for disintegration by the left-hand wheel 22, both wheels discharging the material radially through the sifting drum along paths 27. In other embodiments, a worm is disposed between the coarse disintegration wheels 19 and screen 20 to assist in forcing the material through the screen, and the crushing grid is replaced by radial bars secured to the casing of the apparatus.

Abstract: 1,230,739. Change-speed gear. GENERAL MOTORS CORP. 2 April, 1970 [1 May, 1969], No. 15653/70. Heading F2D. An angle-input transmission between input and output shafts 11, 12 on a heavy motorvehicle, providing hydraulic direct-drive and reverse, and mechanical direct-drive and overdrive, and also in some forms, reverse, comprises a single- or two-train planet gear 22 having its carrier braked at 124 for reverse, its sun 112 braked at 98 for overdrive and locked to output 12 (or input) by a clutch 138 for direct drive, the carrier 120 of the train being driven by an input bevel gear 16, 18, either directly through a direct clutch 14 for mechanical drive, or its sun 112 being driven through a converter clutch 15, a torque converter 20 and selective or one-way clutch 88 for hydraulic drive. In converter drive, using the converter clutch 15, the planet gear is either locked up by the clutch 138 or in reverse by the brake 124. In mechanical drive, using the direct clutch 14, lock-up 138, or overdrive by braking the sun at 98 are available. Fig. 3, not shown, replaces the one-way clutch 88 by a selective disc clutch (88a). Fig. 4, not shown, has two sun-ring trains in parallel, one for reverse, the other for overdrive. The driven member of the one-way clutch (88, Fig. 1) is now connected to the carrier sleeveshaft (55, Fig. 1) and the lock-up clutch (326) is between that sleeve shaft and the intermediate shaft (92, Fig. 1). This permits an all mechanical reverse as well as the hydraulic reverse. Fig. 5, not shown, obtains both mechanical and hydraulic reverse by a single train, with the lock-up clutch (426) arranged, as in Fig. 4, not shown, and there is an additional clutch (428) between the sleeve-shaft (55, Fig. 1) and the input planet-carrier (442), the two clutches (426, 428) being in series for lock-up.

Abstract: 1,259,632. Reverse osmosis. A B C O R WATER MANAGEMENT CO. Inc. 7 Jan., 1969, No. 927/69. Heading B1X. [Also in Division B5] Reverse osmosis, particularly the desalination of saline water, is effected using a membrane prepared by casting a solution of cellulose acetate in an organic solvent to form a film in an atmosphere which is saturated with solvent vapour so that no evaporation of solvent from the film takes place; the film is then immersed in water to separate the organic solvent (see Division B5). In a desalination process, saline water under pressure may be kept turbulent during the process in order to prevent the accumulation of a high salt concentration near the reverse osmosis membrane. Desalinated water passes through the membrane. Salt water, still under high pressure, is discharged from the apparatus through a turbine in order to recover energy for the pump. The separation of viruses and proteins in bio-medical research is mentioned.
