Abstract: 623,542. Sliding-clasp fasteners. GOODRICH CO., B. F. June 7, 1945, No. 14441. Convention date, Sept. 1, 1944. [Class 44] [Also in Group XXXIV] A sliding clasp fastener adapted to seal an opening has overlapping sealing strips along each edge, a slider serving to bring the strips into overlapping position on closing as well as causing interengagement of the fastener elements, and a closure for the end of the opening comprising a cap or housing adapted to be secured to and cover the slider and having tapering marginal edges of elastic material which are brought into contact with a sealing surface. The arrangement includes a slide fastener 15, Fig. 2, and an enclosure structure 16 at one end thereof, applied to an opening in a wall 17 of fabric, &c. The stringers of the fastener are attached e.g., by adhesive, and sealing strips 24, 25 including lateral tapered portions 26, 27 are mounted on the meeting edges of the stringers over the fastener elements. At the end not shown, the contacting faces of strips 24, 25 are attached together by adhesive, and a strip of material superposed at the other end, where the slider rests when the opening is closed, sealing is effected by the cap or housing 16 detachably connected with the slider. This cap engages the surface of a platform 37, which is less flexible than the structure as a whole. Platform 37 is integral or continuous with sealing strips 24, 25, which are cut away at the end to leave an opening 40, and stiffening means such as steel wires 51 may be incorporated. The cap or housing 16, Fig. 3, is of moulded rubber or the like, of generally elliptical form, the side walls being outwardly splayed and tapered, and has a stiffening plate 60 moulded or secured therein. It is retained in position by means of a snap fastening the socket part of which is mounted on plate 60 while the stud forms part of the slider. A pull-ring 73 is mounted on the cap, and a link 74 connects the plate 60 with a slot in the slider. The latter includes a top plate 79, and a flanged bottom plate 80, united by a post 81, and the projecting top part 75 extends from the post 81 forwardly and spaced from top plate 79 so as to afford passage for sealing strips 24, 25. The leading edge of the post between plate 79 and part 75 is tapered and slightly off-set from the centre line to facilitate the opening and spreading action on the sealing strips. In a modified form the cap is mounted on the slider 91, Fig. 8, by means of a threaded pin 104.

Title: Improvements in bearings
IPC: F16C32/06
Filed: 1946-07-25
Abstract: 642,940. Fluid bearings. GERARD, P. L. J. July 25, 1946, No. 15180/49. Divided out of and addition to 642,891 under which a Specification was laid open to inspection under Sect. 91 of the Acts, July 25, 1946. [Class 12 (i)] The surface of a fluid bearing supporting or guiding a movable element has a series of circumferentially wide fluid receiving chambers each spaced by two circumferentially narrow similar chambers, and all the chambers are spaced by longitudinally extending fluid discharging or conveying grooves, the movable element being centralised by the throttling effect on the fluid flowing from the chambers to the grooves via the bearing surface. As shown, a shaft 1 is supported in a bushing 2 having peripheral annular grooves g<SP>1</SP> and g<SP>5</SP> in communication with inlet and outlet conduits 6, 5. The bushing bore has three circumferentially wide chambers a connected respectively by passages c<SP>2</SP> ... c<SP>4</SP> with intermediate peripheral annular grooves g<SP>2</SP> ... g<SP>4</SP> and each chamber is spaced by two circumferentially narrow fluid receiving chambers a<SP>1</SP> connected by passages c<SP>1</SP> to the groove g<SP>1</SP>. Between each pair of chambers a<SP>1</SP> is a longitudinally extending groove b connected to its diametrically opposite chamber a by further respective passages c<SP>2</SP> ... c<SP>4</SP> communicating with the grooves g<SP>2</SP> ...g<SP>4</SP>. Between each pair of chambers a, a<SP>1</SP> is a longitudinally extending groove b connected by a passage c<SP>5</SP> with the annular groove g<SP>5</SP>. Fluid flows into the groove g<SP>1</SP> and to the passages c<SP>1</SP> and both narrow chambers a<SP>1</SP> of each group, from whence it passes along the bearing surface to the middle groove b and via the appropriate passages c<SP>2</SP>, g<SP>2</SP> ... c<SP>4</SP>, g' to the diametrically opposite wide chamber a, and. again via the bearing surface to the adjacent grooves b, through the passages c<SP>5</SP>, groove g<SP>5</SP> to the outlet conduit 5. Any tendency of the shaft to contact the bushing for example, in the region of the lower chamber a, is countered, on widening of the opposite bearing gap between the receiving chambers a<SP>1</SP> and middle groove b and construction of the bearing gap between the chamber a and its discharge grooves b, by the consequent changes in fluid pressure. The circuit, being symmetrical, balances the shaft in all directions.
