A lift-valve closure member 4 controls fluid flow from an inlet 2 to an outlet 3, the member 4 having a relatively rotatable connection 5 with a spindle 6 of triangular cross-section formed by arcs of circles. The valve body 1 is provided with a cover 7 which has a bonnet 8. The part of the cover 7 co-operating with the triangular section of the spindle has a complementary shape to prevent rotation of the spindle therein; an insert may be disposed between the spindle and cover. Valve operation is effected by a differential screw-threaded means comprising a sleeve 10 into which the spindle is threaded, the sleeve 10 in turn being screwed into the cover 7; the internal and external threads of the sleeve are of different pitch and of the same or opposite hand. The spindle may be operated by a key or hand wheel. Alternatively the valve may be actuated by a rotatable bush axially located in the cover. The joint faces 7e, 1e are sealed by welding 11, an annular groove if in the face 1e is provided to house an " O " ring for initial assembly testing purposes prior to welding, and opposite face grooves are incorporated to allow free access of fluid to and from the welds to ensure the latter will stand the pressure. A similar arrangement is used in the flange connection between the bonnet 8 and cover 7. The spindle 6 is sealed in the latter by an " O " ring 14 or a bellows.

Abstract: 700,843. Taps. HAYCOCK, H. J., and WILSON, H. G. C. Feb. 19, 1953 [March 3, 1952], No. 5469/52. Class 83 (3) A tap for cutting threads to the bottom of blind holes has the leading end-face 3 of each land 2 backed off at an angle (indicated at b), which is at least equal to, and is preferably greater than, the helix angle (indicated at h), of the tap thread, so that the trailing edge 4 is clear of the cut 9 made by the cutting-edge 5 in the conical bottom of the hole. The possibility of breakage of the tap, which may be caused on reversal by the torsional strain on the end of the tap in breaking the locking action resulting from the reaction of a flat-bottomed tap on the bottom of the hole, is thus reduced. The tap may have straight flutes but, to assist in swarf removal, the flutes 1 are preferably helically formed at 27 degrees to the tap axis, as shown, or at 45 degrees or any other angle.

Abstract: 231,644. Cudmore, A. E. March 4, 1924. Moulding walls in situ.-Walls are cast on a platform normally horizontal which can be swung up so as to position the set wall on to the foundation and be then withdrawn leaving the wall in position. The shuttering 7 is supported by swinging frames 6, each of which is carried by a fixed framework 1 to which the frames are connected by swinging levers 15. The back member 3 of each fixed framework is formed as a U-bar opening upwards, in the lower part of which is a joint 13 which is adapted to operate a lever 11 pivoted to the swinging frame to cause the frame to swing about the lower end of the lever 15. Each swinging frame is provided with a removable foot portion 9 which supports the wall during the swinging movement and from which the platform may be then detached and withdrawn prior to its being swung back to its original horizontal position by ropes 25, 26 operated by rotating drums in the frame. These feet may be subsequently removed from the cast wall and the openings filled. Each swinging frame has pivoted to its rear end a platform 28 connected by a lever 31 to the fixed frame, so that as the swinging frame is erected the platform 26 remains horizontal and' may operate as a hoist for material.

Title: Improvements in or relating to air supply regulating equipment for burners
Inventor: SHERLOCK JOHN EDWARD
IPC: F23D5/00
Filed: 1955-02-24
Abstract: 809,411. Air supply to burners. BRITISH THERMOSTAT CO. Ltd. Feb. 24, 1956 [Feb. 24, 1955], No. 5594/55. Class 75(1) A burner air supply regulator comprises a pivoted damper plate provided with a movable valve element slidably co-operating with a stationary valve element, the damper plate being adapated in response to a change in air pressure within or beyond the burner to rotate about its pivot to cause the valve elements to control the amount of air admitted to the burner. In the arrangement shown, in Fig. 1, a damper plate 17 is vertically supported on a pivot 18 and counterbalanced by an adjustable weight 10. The sides of the damper plate 17 are spaced away from the surrounding passage and an increase in air flow past the plate 17 causes a clockwise movement thereof which in turn reduces the overlap between a slit 20 formed in a curved plate 19 on the damper plate 17 and a slot 22 in a stationary plate 21 thus throttling the air supply to the burner 2. In this arrangement the damper plate 17 is responsive to the air conditions at the burner entrance. In the arrangement shown in Fig. 2 the damper plate 17 is responsive by means of an air passage 23 connected to a combustion chamber 25 to the air-flow past the damper plate 17 depending on the air pressure conditions above and beyond the burner 2 and in this case the air passes through the slots 20, 22 in the slide valve into a chamber 24 opening into an outer chamber 1. The air supply regulator may be made as a self contained unit which may be fitted to any type of burner including a solid-fuel burner. Specification 785,374 is referred to.

Title: Improvements in or relating to Electrical Means for Indicating or Transmitting Movements.
Inventor: WRIGHT HENRY ROBERT
IPC: G08B5/22
Filed: 1916-04-17
Abstract: 102,104. Wright, H. R. April 17, 1916. Order and order-type apparatus.-In a system comprising a source of direct current, a variable resistance, and an ammeter or the like, the movement of the measuring-instrument is more rapid than the movement to be indicated. Two or more measuring-instruments having different speeds may be employed, and arrangements are provided for adjusting the instruments by means of shunts. In the arrangement shown in Fig. 2, the arms 21, 28 of rheostats 19, 26 are geared together by means of wheels 11, 12. The variable rheostat 26 controls the current supplied from a battery 1 to an ammeter 27; while the rheostat 19 similarly controls the current supplied to an ammeter 20. The ammeter 27 is so arranged that the angular movement of its needle is faster than that of the arm 28, while the needle of the ammeter 20 moves one division for one complete throw of the needle of the ammeter 27. The ammeters are calibrated by the insertion of a constant resistance 29 into their circuits by means of switches 22, 23 and by variably shunting the ammeters. In a modification, the rhostats 26, 19 are replaced by potentiometers. In the modification shown in Fig. 3, a circle 6<2> provided with a fiduciary mark 17 is geared to a circle 9<2>, having four gauge marks, by gear-wheels 13, 14, 15, in the same ratio as the gearing between the arms 5, 8 of the potentiometers 7, 4. The wheel 13 is provided with an arm 16, which, when moved to cause the pointers 6<1>, 9<1> to agree with their fiduciary marks, occupies the same angular position as the transmitter arm 10. The potentiometers may be replaced by rheostats. Other indicators and transmitters may be employed to secure greater accuracy.
