Title: Improvements in gates
IPC: E06B11/02
Filed: 1929-05-21
Abstract: 327,623. House, H. May 21, 1929. Collapsable gates.-A gate comprises a number of horizontal, flexible members 4 such as chains connected by a number of vertical chains 5 and secured at one end to an angle member 6 by means of adjusting nuts 8. The angle member is removably carried between the limbs of U-shaped members 9 fixed to a post 1, vertical movement of the angle member being prevented by stops 10 projecting therefrom and engaging the members 9. The other ends of the chains are secured to a vertical chain 11 which is secured at its lower end to a framework 13 fixed to the post 2 and at its upper end to a link 17 slidable on one arm 15 of a lever 14 pivoted at 25 to the post 2. A bell-crank lever 23, 24 is also pivoted at 26, and to the lower end of the arm 24 of this lever another lever 29 is pivoted, the lever 29 carrying a pulley 31 and being linked by a link 30 to a latching member 26 which is pivoted to the lever arm 24 and is normally drawn by a spring 28 into latching engagement with a projection 27 carried by the frame 13. The weight of the lever 23, 24 and the action of a spring 38, anchored at one end to the frame 13 and at the other to the arm 23, normally cause the lever 23, 24 to take up the position shown wherein the arm 23 engages a shoulder 22 on an arm 20 which is pivoted at 21 to a catch 18 normally held, by a spring 19, in engagement with the upper end of the lever arm 15. A cord passes round the pulley 31 and around two fixed upper pulleys 33, its free ends 32 being provided with stop members 36. Upon a downward pull on either free end, the lever 29 is rocked counterclockwise to release the latch 26 whereupon the lever 24, on continued pull on the cord, rocks counterclockwise about its pivot 25, the arm 23 drawing the arm 20 downwards against the spring 19 to release the catch 18 from the lever arm 15, which then falls to the dotted position shown, the link 17 travelling along the lever to its head 16, and the chains collapsing on to the ground at this end. In this position of the lever arm a lug 40 projecting therefrom will have been swung to a position in which it abuts against a projection on the lever arm 23. After the cord has been released a subsequent downward pull on either free end rocks the lever 23, 24 as before, but in this case the projection on the arm 23 engages the lug 40 to swing the lever 15 up again and restore the chains 4 to their horizontal position, the movement of the link 17 along the lever 15 being aided by a cord 41 secured to the link. To permit the passage of wide vehicles, after the chains have been collapsed by actuation of the lever 15, the angle member 6 is removed from the post 1.

Abstract: 1,033,879. Rotary screw pumps. A. B. FLYGTS PUMPAR. April 14, 1965 [Aug. 18, 1964], No. 16103/65. Heading F1F. A rotary screw pump comprising a pump body having an inlet section 10, an outlet section 12 and a sleeve 14 clamped therebetween within which is mounted a fixed resilient stator 16 of, e.g., hard rubber, having a twostart helical thread engageable with a one-start helical thread of half the pitch on a rotor 20 which revolves and simultaneously moves eccentrically within the stator so that closed pockets between the rotor and stator are moved axially from the inlet to the outlet includes a clearance between the sleeve and stator and connected by a channel 18 to the inlet section 10, so that a slow flow of pumping medium passes from the outlet to the inlet. In operation, pressure in the pumping chamber increases linearly from the pump inlet to the pump outlet resulting in deformation of the elastic material of the stator corresponding to pump pressure with a tendency for leakage to occur across the tips of the rotor threads near the outlet and the rotor to "squeeze" into the stator near the inlet with a resulting loss in pump efficiency. The small flow through the clearance nullifies this tendency, the pressure through the clearance decreasing linearly from the outlet to the inlet of the pump so that at any point along the length of the stator the pressure prevailing inside the pump chamber is balanced by the pressure in the clearance. The flanged end 16a of the stator 16 may be at either end, providing a small flow at progressively decreasing pressure takes place through the clearance from the outlet to the inlet.
