Title: Improvements in or relating to fluid pressure operated blowers for cleaning the tubes of steam generators and the like
IPC: F28G3/16
Filed: 1936-11-23
Abstract: 487,861. Boiler &c. cleaners. IVOR POWER SPECIALITY CO., Ltd., and MOSES, R. I. Nov. 23, 1936, No. 32032. [Class 99 (ii)] In a blower for cleaning the tubes of boilers &c. of the kind in which the blower tube 5, Fig. 1, is provided at its inner end with a nut 6 for engagement with a thread 2 on a central cleaning-fluid supply conduit 1, the conduit 1 is rotatably mounted within a tubular casing 52, extending from the blower wall box 36, and is in clutch engagement with a sleeve valve 8 which is located in a casing 58 at the end of the casing 52 and normally bears on a seating 74, axial movement of the conduit being prevented by collars 64, 68 abutting against a bush 62 secured to the said valve casing 58. The blower tube is also provided with a longitudinal featherway 26 slidably engaged by a feather 28 fixed in the bore of a driven gear-wheel 29 coupled to a hand wheel &c. 88, and, as shown in Fig. 1a, the adjacent ends of the collar 68 and valve 8 are provided with coacting clutch teeth 78 and the external surface of the valve is formed with a cam groove 10 for engagement by a stud 11 projecting from the casing 58. The arrangement is such that rotation of the blower tube in a clockwise direction will cause the nut 6 to travel along the supply conduit and impart an axial movement to the blower tube until the latter is in its projected or operative position and the nut abuts against a bored collar 14 on the end of the conduit. Continued rotation of the blower tube will then cause the conduit to rotate and with it the valve 8, the cam groove 10 and stud 11 coacting to open and close the valve so that cleaning fluid is supplied to the blower tube in intermittent gusts. Rotation of the gear-wheel 29 in the opposite direction will first cause the blower tube to return to its original position, and, when the nut 6 abuts against the collar 64, the conduit 1 will again rotate and with it the valve 8 until a step 13 in the groove 10 bears against the stud 11. and prevents further rotation. In a modification, the valve seating 74 is floatingly mounted in the casing. Fig. 3 shows a, construction in which the valve 100 is located'in a T-piece 102 on the end of the supply conduit 1, opening and closing of the valve being effected during rotation of the conduit by the engagement of a projection or extension 107 of the valve with an interrupted cam ring 108 fixed in the casing 116. The valve is normally held on its seating 105 by a spring 130 located between the back of the valve and a plug 132 fitted in an apertured member 130.

Abstract: 385,406. Aircraft with rotary-wing systems. RAWSON, A. H. C. A., Bush House, Aldwych, London. Nov. 19, 1931, No. 32152. [Class 4.] In an aircraft of the type having a normally wind driven sustaining rotor, an engine for forward propulsion, driving means for connecting the engine with the rotor for imparting to the latter an initial rotation before taking flight, and having means for operating brakes on the running wheels of the craft, the brake operating means are interconnected with the means disconnecting the rotor driving means and are so arranged that on release of the wheel brakes to permit the aircraft to start, the drive from the engine to the rotor is automatically disconnected. Fig 1 shows an aircraft having rotor driving means comprising two drive units 14, 19 associated with engine 13 and rotor hub 20, respectively, the unit 14 comprising a friction clutch engaged by downward movement of a lever 15 against the restraint of a spring 27, and the unit 15 comprising a dog clutch engaged by upward movement of a lever 24 against the restraint of a spring 25. Each of these levers is provided with means for holding them in the engaged position against the action of their pull-off springs which means are actuated by Bowden cables 33, 34, respectively, tensioned upon application of a brake lever 29. Lever 15 is fitted with a pawl adapted to co-operate with a pivoted ratchet 28 normally held clear of the pawl by a spring and moved into operative position by a resilient connection to wire 33<x> of cable 33. Lever 24 works in a gate 26, Fig. 3, having a notch 26<x> with which the lever is normally prevented from engaging by a spring 50. The tension member 34<x> of cable 34 is arranged, on operation of lever 29, to overcome the pull of spring 50 and hold lever 24 in the notch 26<x>. Lever 29 works in a quadrant 30, Fig. 5, to the lower edge of which are anchored the outer members of the Bowden cables 33, 34 associated with the clutch lever holding means, and a further cable 31 of which the tension member is connected to the mid point of a cross-bar 60, Fig. 6, connected at its outer ends by cables 32 to the brakes. Lever 29 is fitted with a pawl 52 engaging in a ratchet formed on quadrant 30. This pawl is releasable either by depressing a knob 55 on the lever or by remote control means operable from a rear cockpit and comprising a lever 37, Fig. 1, and Bowden cable 36 having its tension member 36<x>, Fig. 5, connected to the pawl as shown. Means for differential actuation of the brakes from either cockpit comprise rods 61, Fig. 6, linked to a rudder bar 63 pivoted at 63<x> which rods are connected to cross-bar 60 in such a way as to permit of their operating in tension only whereby movement of the rudder bar does not affect the brakes when the cross-bar 60 is pulled bodily forward on application of lever 29. To each end of rudder bar 63 is attached a stirrup 65 having a pedal 66 and a rearward extension 67 carrying a pedal 68 for use by the occupant of the rear cockpit.

Title: Improvements in or relating to double-conductor trolley systems for electric vehicles
IPC: B60M1/14
Filed: 1936-11-24
Abstract: 485,760. Overhead conductors for electric vehicles. STEVENS A. H. (Holden, Inc., R. R.) Nov. 24, 1936, No. 32172. [Class 104 (iii)] A double-conductor trolly system, comprises main conductors 15, 15<1>, branch conductors b, b<1>, m, m<1> and a pair of switches D, D<1> for guiding the collectors from the mains on to either of the branches, said switches being normally in a neutral position with respect to the branches and provided with means for guiding them into alignment with the mains and either of the branches, means for controlling said guide means, and means interconnecting the two guide means of the two switches to cause them to be similarly actuated. As the car approaches the switches, one collector lifts a shoe 102 pivoted to two bell-cranks 103, which carry a rod 107 connected at the forward end to a bell-crank 117. The forward movement of the rod 107 rocks the lever 117 which engages a pin 121 carried by a rotatable disc 122 and turns the latter so that a radial slot 125 therein lies parallel to one slant edge of a fixed adjacent plate 124, as shown in dotted lines in Fig. 7, the normal position being in full lines. A similar disc associated with the other switch D<1> is connected to 122 by a rod 127<1> so that both discs assume the same position. If the car is running straight through on to lines m, m<1>, the two collectors are in the same plane transverse to the lines 15, 15<1> and engage the two switches D, D<1> which are hung from bell-cranks 130, 131 and carry arms 128 provided with pins 126 passing across the edges of the plate 124 into the slots 125 of discs 122. The lift of the switches causes the pin 126 to move up the slots 125 towards the right as seen in Fig. 7, thus sliding the switches laterally along their pivot pins 135 into alignment with the through lines m, m<1>. If the car is turning a corner, one collector is ahead of the other, so that while one is lifting the shoe 102, the other engages the switch D<1>. The lifting of 102 turns the slots 125 into the dotted position of Fig. 7, while the lifting of D<1> moves the pin 126 up the slot 125 towards the left as seen in Fig. 7 and slides the switch D<1> into alignment with the branch b<1>. The other collector then engages the switch D and in the same way moves it into line with the branch b.

Title: Fuel rod structure
IPC: G21C3/322
Filed: 1965-07-29
Abstract: 1,088,894. Fuel elements. ATOMIC ENERGY OF CANADA. July 29, 1965 [Aug. 28, 1964], No. 32455/65. Heading G6C. The fuel rods of a cluster-type fuel element are spaced from one another by small protuberances or warts located in longitudinally spaced transverse planes. In one embodiment (Fig. 2), the cluster 1 comprises a central fuel rod 11 and inner and outer rings 12, 13 of fuel rods which are fastened together by means of slightly flexible end-plates. The outermost parts of the surfaces of the outer ring 13 of fuel rods carry wear pads 10 which engage the walls of the passage of the reactor into which the fuel cluster is placed. Warts are brazed or welded on to the surfaces of the fuel rods in those regions where they will be most deformed, the warts on each fuel rod engaging corresponding warts on the adjacent fuel rods. The surfaces of the warts may be slightly cylindrical rather than flat so that there is line contact between adjacent warts. The warts are arranged in three different transverse planes, located near the centre of the cluster, and designated left, central and right planes. The co-operating warts 24 on the fuel rods of the outer ring 13 and the co-operating warts 21 on the fuel rods of the inner ring 12 lie in the central plane. The warts 22 and 23 between the inner and outer ring fuel rods are alternately in the left, right, right left planes (Fig. 3, not shown). The six warts 19 on the inner fuel rod 11 and the warts 20 on the inner ring fuel rods with which they cooperate are alternately in the left and right planes. The advantage of staggering the planes of contact of the warts in this manner is that there is little interference with coolant flow in the axial direction of the cluster and the surface over which interacting forces between fuel rods operate is extended. In an alternative arrangement of the cluster, there may be no single central fuel rod but a central cluster, there being, for example, three or four fuel rods in this central cluster. While a cluster with three planes of warts is described, it may sometimes be desirable to have two, or four or more planes, or groups of planes, along the length of the cluster. The cluster need not be of circular array but may be square, hexagonal or of other polygonal shape.
