Filed: 1937-09-22
Abstract: 492,127. Lifting-slings. PAINE, H. SCOTT-. Sept. 22, 1937, No. 25743. [Class 78 (iv)] A sling, more especially for lifting boats, comprises a number of closely-arranged spaced parallel ropes secured at their ends to a common rigid member engaged with the lifting-tackle. Figs. 1, 2 and 3 show two slings used in combination for lifting a boat bodily. - Each sling comprises a number of ropes 12, which are spaced at intervals by detachable groove plates 24 bolted round them, and are formed with eyes at their ends for connection to triangular plates 15 by means of the bolts 17, Fig. 3. Curved spaced plates 23 are fitted at the points where the sling passes round the chine of the boat. Ropes 27 pass from the plates 15 to a common lifting-hook 39. A connecting rope 30 with a straining-device 31 and two ropes 30 lashed to bollards on the boat maintain the sling in position. Preferably two additional members 34 with spring or other resilient sections 37 pass directly from the boat to the lifting-hook between the ropes 27 and apply a graduated initial lifting effort before the ropes 27 take up the strain. All metal parts which contact with the hull are padded with rubber or the like, and bearing members 40 for the ropes 27 are fixed to or fitted detachably on the gunwale. The use of one sling for raising one end only of the boat is described.

Filed: 1927-10-05
Abstract: 295,855. Weir, Ltd., G. &, J., and Sim, J. Oct. 5, 1927. Feedwater, supplying. - The condensate from the condenser h of a steam power plant is fed to the boiler through a deaerating chamber a, and make-up feed is supplied to the chamber from a tank v, the flow of condensate and make-up into the chamber being controlled by valves t, w, which are so operated by a float 3 in the chamber that make-up is drawn on only when the water in the chamber falls below a certain level. The make-up is passed through a steam-heated heater x and flashes into steam upon entering the de deaerating chamber. The condensate enters the deaerating chamber through spraying nozzles and is used on its way to the chamber as a cooling medium in the condenser c of the ejector e drawing air and vapour from the chamber. Excess condensate passes into the tank v through a pipe 11 and a non- return valve 12. Water passes from the tank through a non-return valve 14 and pipe 13 into the feed pipe between the booster pump 4 and the feed pump 7 when the booster pump fails.

IPC: F02C7/224
Filed: 1957-08-20
Abstract: 843,928. Gas turbine fuel systems. ROLLSROYCE Ltd. Aug. 14, 1958 [Aug. 20, 1957], No. 26331/57. Class 110 (3). [Also in Group XXIX] A fuel heating system for a gas turbine comprises a fuel pump 16 delivering to a heat exchanger 18 supplied with heated air from the compressor 11 through pipes 23a, 23b, the flow of air being regulated by a gate valve 31 actuated by a fluid-pressure servomotor 24 controlled by a temperature-responsive element 25 in the outlet pipe 17b from the heat exchanger. The servomotor comprises differential pistons 37b, 38b working in cylinders 26, 27, and between which the gate valve 31 is mounted, the piston 38b carrying a tapered plug 38d movable within an orifice 39 between a chamber 28 and that portion of cylinder 27 to the right of piston 38b. In operation the air from inlet pipe 23a passes into the space between pistons 37b, 38b, then via a passage 38e in piston 38b and plug 38d into chamber 28, through orifice 39 and a pipe 40, and finally discharges into atmosphere through a second orifice 25c, the area of which is controlled by a needle valve 25b whose setting is varied in accordance with the temperature of the fuel in the outlet pipe 17b. The variation in the pressure of the air acting on the right-hand surface of piston 38b consequent upon movement of needle valve 25b results in movement of the differential piston unit and gate valve 31, by which the flow of hot air through pipes 23a, 23b is regulated, the arrangement being such that movement of tapered plug 38d in orifice 39 tends to restore the pressure of the air in the right-hand portion of cylinder 27 to its original value upon any variation thereof due to operation of needle valve 25b. Leakage past piston 38b is minimized by providing the latter with a recess 27b communicating with atmosphere through a passage 38f, at the end of which is a variable orifice 41, by adjustment of which the pressure in recess 27b may be made equal to that on the right of piston 38b.

Abstract: 760,647. Endless conveyers. AKTIEBOLAGET HARBOR. Sept. 13, 1954, No. 26492/54. Class 78 (1). In a conveyer of the kind wherein carriers for the load are supported between two parallel and spaced endless chains or cables, guides are provided along the return run of the conveyer to engage projections on the chains or cables and enable the chains or cables to hang in loops between the projections whilst these latter advance along the guides. As shown, goods are unloaded from the hold 6 of a ship lying alongside a quay 1 by a conveyer comprising a pair of endless chains 8 having rods 9 between them supporting fabric pockets 10 carrying the goods. The chains pass round terminal pulleys 11, 12 and driving sprockets 13, 14 driven by an electric motor 15 through shafts 16 provided with disengageable couplings 17 and braking devices 18. The conveying run of the chains passes over guide sprockets 13a, 14a which may be freely rotatable or driven by the motor 15 in a similar manner to the sprockets 13, 14. When the ship is being unloaded, the rods 9 after passing round the sprockets 14 are engaged by projections (not shown) on pulleys 21 driven synchronously with the sprockets 14 and transferred to a pair of guides 19 down which they move to the bottom and are then raised over the wheels 13, the chains hanging in loops whilst the rods are passing along the guides. If unloading is to take place from the hold 5, the guide pulley 11 is moved to its lower position 11a by temporarily stopping the sprockets 14 by disengaging the associated coupling 17 and tightening the corresponding brake 18 whereby the chains are pulled from the guides 19 by the sprockets 13. If the pulley 11 is to be returned to its upper position, the sprockets 13 are disconnected and braked. When the conveyer is to be reversed, the guides 19 are tilted about the shaft 20 to the chain-line position,. Pulleys 23 having projections similar to the pulleys 21 assist in the transfer of the rods to the guides. Plates 24 discharge the goods from the pockets 10.

A piled-element radiator core comprises a plurality of hollow aluminium plates 1, 1a . . . in, each of which is made of two plates placed together in such a way so as to define a plurality of channels 2 connecting two collecting chambers 3, of which only one is shown, each chamber being symmetrically disposed on either side of the plate and having a flange 4 upon which rest the flanges of adjacent members. Intercalary strips 14 are provided to enhance head dissipation. Correct positioning of the plates during stacking is achieved by having the corners of the plates bent along concurrent lines 6, 7 to form flaps 8, the flaps being of height greater than the distance between adjacent plates and making an angle slightly in excess of 90 degrees with the plane of the plate as a result of which on stacking the flaps overlap and so ensure proper alignment. When stacked, the radiator core is placed in a flux bath for brazing at the flaps and at the flanges 4, after which walls 5 of the collecting chambers 3 are perforated to form a continuous header. In an alternative embodiment (Figs. 2 and 3, not shown), the ends of the hollow plates are bent over along their entire width so as to delimit tongues (10) whose height is greater than the space between adjacent members, the tongues being provided with stampings (12 and 12a), which act as further centring means.
