Title: Improvements in brake rim construction
IPC: B66D1/06
Filed: 1931-03-18
Abstract: 365,403. Brake drums. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (National Supply Corporation ; 120, Broadway, New York, U.S.A.) March 18, 1931, No. 8312. [Class 103 (i).] A brake drum more particularly for the winding drums of draw-works for high speed well drilling is mounted to float on the supporting means to allow of expansion due to heating by braking and contraction on cooling. It comprises a mounting having a fixed annular flange 1b, a movable annular flange 15 and a brake drum 24 adapted to float on the mounting and being driven by lugs 28 fitting in keyways in the drum 24 and the flange 1c. The drum 24 is narrower than the flange 1c in order that it may expand transversely when the flange 15 is clamped in place by the bolts 16. The flange 1c and the drum 24 are provided with recesses 12, 27 into which cooling fluid is introduced through openings 13 by means of pipes 33. Leakage of cooling fluid past the brake drums is prevented by packing 19 in counterbores in the flanges 1b, 15. Counterbores 17, 17a in the flanges 1b, 15 prevent brake drum parts flying from the machine in case of fracture. In a modification the brake drum is provided with thicker wearing surfaces, and larger holes 13 and a larger bracing web 35. This brake drum mounting is arranged at each end of a winding drum, a flange 1b being cast integrally with each end of the winding drum.

Title: Improvements in connection with supports for illuminating and other glassware
IPC: C03B9/32
Filed: 1928-03-20
Abstract: 313,659. Hailwood, E. A. March 20, 1928. Securing globes &c. to holders.-A globe or like glass article is detachably secured to a support by means of a cement liner C cast around or partially around a flange N or other portion of the globe. The outer surface of the liner may be smooth or moulded, painted or enamelled, and ingredients may be mixed with the cement to give it a white or other colour. The liner may be provided with inserts of elastic material to allow of expansion or contraction of the liner when setting, and with recesses R, Fig. 4, to receive rubber rings to form a water or air tight joint between the liner and the support. The liner may be secured to the support by means of a bayonet joint, it may be provided with holes or with plugs of wood or like soft material to receive holding screws. Alternatively the pressure of the screws may be taken by means of plates of sheet iron or steel embedded in the liner. When the globe is fixed to the top of a column the liner C may be formed with a flange C<1>, Fig. 7, to drain off rain or other water and its lower part may be reinforced by a metal ring M. The liner may be reinforced such as by wires W some of which may be shaped in the form of outstanding bars or loops W<1> to form means for detachably securing the globe and the liner to the support. As shown in Fig. 11, the wires W may also serve to hold together a liner formed by a number of disconnected parts. Specification 3291/00 is referred to.

Title: Mooring gear for flying boats
IPC: B64C35/00
Filed: 1944-05-05
Abstract: 575,919. Hooks. SAUNDERS-ROE, Ltd., and KNOWLER, H. May 5, 1944, No. 8485. [Class 89 (ii)] [Also in Group XXXIII] Mooring gear for a flying boat, Fig. 1, is retractable into an opening 10 in the keel 11 and comprises a hook 14 pivoted at 13 to a casting 12 fixed to the upper surface of the keel. The position of the hook is determined by a link 15, pivoted to the hook and on a pin 17 fitted to a lever 18 fixed on a shaft 19. Shaft 19 is rotatable by remote control from the cockpit. In the operative position of the hook, Fig. 1, a surface 20 of link 15 abuts a surface 21 of lever 18 thus constituting a rigid support for the hook. Pivoted at 22 to the hook is a latch 23 loaded by a spring 24 fixed to a plate 25 carrying arms 26, 27 pivoted to the hook at 28, 29. A link 30 is pivoted at 31 to the catch 23 and is formed with a slot 32 engaging pin 17. In operation, forward movement of the flying boat after alighting will engage mooring cable 33 with the hook, the slot 32 allowing movement of catch 23 against spring 24. To cast-off, the shaft 19 is rotated clockwise. Initial rotation brings the parts to the position of Fig. 3 (not shown), pin 17 operating throughlink 30 to open the catch. Aft drift of the boat will now disengage the cable. Further rotation of shaft 19, see Fig. 4 (not shown), retracts the hook sufficiently to allow disengagement by forward drift of the boat. Should the boat be entirely stationary during casting-off, arm 26 operates to eject the cable and force it beneath the keel, see Fig. 5 (not shown). In the fully retracted position, Fig. 6, the plate 25 closes the opening in the keel. Anti-clockwise movement of shaft 19 returns the hook to the operative position. Specification 575,723, [Group XXXIII], is referred to.

[Also in Group XXXVIII] A rotating drum switch in a sonic echo sounder (see Group XXXVIII) comprises a rotating drum 29 of insulating material having a helical conducting strip 33 inlaid in its surface and two co-operating axially displaced brushes 34 and 35 are mounted on spring- loaded fingers 36 attached to a support 39 by screws 37 and 38 passing through longitudinal slots 36a in the fingers. The drum is rotated by a constant speed motor 32 through gearing 31 and an electrical circuit is completed for a short duration each time the strip 33 makes simultaneous contact with the two brushes and the phasing of the contact time relative to the drum rotation is adjustable by moving the support 39 parallel to the axis of the drum by means of a screw 48. The front and rear edges of the brushes are parallel to the edges of the strip and the duration of the switching period may be adjusted by altering the relative effective length of the fingers.

IPC: F28F3/08
Filed: 1956-03-21
Abstract: <PICT:0859876/III/1> <PICT:0859876/III/2> In an evaporator which is formed by an assemblage of heat-transferring plates P clamped between heads H but spaced apart by gaskets 9 to provide channels SF for the heating-medium alternating with channels LF for the liquid-being-evaporated, the liquid is introduced through ducts 2 and flows through two sets of registered openings 1 in the lower ends of the plates, the arrangement being such that the liquid flows up between plates P1 and P2, passes through openings 10 and 11 at the tops of plates P2 and P3, and flows down between plates P3 and P4. The concentrated liquid and its evaporated vapour flow through the outlet passage formed by the openings 3, are withdrawn through outlet 4 in one of the heads, H and are separated in separator U. Heating-medium, supplied to the apparatus through opening 6, flows to the heating channels from the passage formed by the openings 5 in the plates.  Plates P1, P3 and P5 are fitted or formed with baffle-strips 12 to compel the heating-medium to follow a tortuous path.  The condensate of the heatingmedium passes through openings 7 to outlet 8.  The width of the downward-flow liquid channel (i.e. the size of the gap between the bounding plates) may, if desired, be made greater than that of the rising flow channel.  Alternatively, three parallel downflow channels could be associated with a pair of upflow channels. Each liquid flow channel may be divided into a plurality of separate side-by-side channels by suitable gasket - strips.  Evaporator units can be combined to form a multiple-effect apparatus wherein the vapour formed in one effect, after separation from the partially concentrated liquid, is supplied to the heating-channels of other effects.
