Title: Rotary sprinkler
IPC: B05B3/06
Filed: 1972-07-07
Abstract: 1402608 Rotary sprinklers M DRORI 7 July 1972 [7 July 1971 12 Nov 1971] 31939/72 Heading B2F A sprinkler which is driven by water jet reaction comprises a riser 3, Fig 1, a flexible pipe 1, a nozzle 6 and an arm 9 carrying bearings 7, 8 which rotate causing twisting of the pipe 1. In the embodiment of Fig 1 the water jet flows through spiral baffles 6b to produce the rotary movement of the arm 9 about the riser 3. A collar 4 transmits jet reaction to the bearing 8. In other embodiments, Figs 2, 4, 5 (not shown), the arm 9 is driven by various mechanisms which essentially comprise a baffle plate rotatably mounted above the nozzle 6 on a vertical post extending from the bearing 8, the plate having depending baffles on which the water jet impinges. Rotation of the plate is transferred to the bearing 8 by means which include a horizontally reciprocable cam plate a gear and worm mechanism, or by a pin and slot arrangement. As shown in Fig 6. the sprinkler oscillates by impingement of 30 carried by pivotally mounted arms 31. If e.g. the right deflector 30 is struck by the jet, rotation of the nozzle 6' is in a clockwise direction and causes lug 38 on a ring 36 to actuate a pivoted bar 40 and thus a bar 45 which arrests upward movement of the. lever 31 by engagement with a stop 46. The other deflector is then hit by the jet and the reverse operation takes place.

A horizontal rotary drum washing and spindrying machine has mounted below the drum 1 a water tank 3 which is used both to store hot washing, water for the machine and to provide a sufficient weight to anchor the machine during spindrying. The water in the tank 3 is heated by immersion heaters 6, 7 controlled by thermostats, and the level of the water is kept constant by a ball valve or pressure-sensitive device (not shown). Water is fed from the tank to the drum by a centrifugal pump 4 and the washing and drying cycle may be automatically controlled including the addition of detergent. Alternatively, the detergent may be added by hand into a hopper 17 when an indicating light is illuminated. The machine may also be adapted for coin operation and suitable safety devices may be provided to ensure that the machine cannot be started until the hot water tank is charged and the drum door closed and locked, and to prevent the door being opened whilst the drum is rotating.

Abstract: 935,905. Measuring electrically. MINNEAPOLIS-HONEYWELL REGULATOR CO. Sept. 21, 1959, No. 32070/59. Class 40 (1). [Also in Group XX] The angular rotation of a shaft is measured by an inductive pick-off comprising an energizing winding, an output winding and an additional biasing winding for reducing the measuring signal to zero when the angular rotation is zero. As shown, a shaft 38 (Figs. 1, 2) carries a bipolar rotor element 62 normally inclined at 45 degrees to the axes of four pole members 64, each of which is surrounded by three coils 70, 72, 74. The four windings 70, constituting the primary windings, are connected in series aiding, and are fed with an A.C. voltage Ep (Fig. 4); the four windings 74, constituting the bias windings, are also connected in series aiding, and are centre-tapped to provide voltages E1; E2 in phase or out-ofphase, with Ep; the four windings 72, constituting the output windings, are connected in series opposition, giving zero voltage when the rotor 62 is located at 45 degrees to the pole axes, and supplying a signal voltage when the rotor is angularly displaced, whose magnitude and phase is indicative of the magntiude and direction of the rotor displacement. A potentiometer 90, connected across the windings 74, enables an adjustable bias voltage to be obtained from these windings to reduce the signal voltage from windings 72 to zero when the angular rotation of shaft 38 is zero. The pick-off is used with a rate-of-turn gyroscope 10 (Fig. 1), whose rotor 50 spins about axis 51, and rotation about an axis 53 (Fig. 2) produces precession about axis 52, along shaft 38, which is attached to a fixed stub 40 by torsion spring members 42.

[Also in Division C3] A metal ingot mould 1 has holes provided through its walls and a permeable sand liner 3 covering the holes so that a gas stream may pass through the liner 3 and the holes to carry away any gases generated from the liner and molten metal and so improve the surface quality of the finished ingot. The holes may be filled with copper wires, steel wires, or sintered iron permeable to gases. The gas stream may be air or inert gas, e.g. argon, helium or nitrogen and is caused to flow by reducing the pressure in a surrounding vessel 8 by a vacuum pump, an exhaust fan or a steam ejector. Molten metal is poured in via a sprue runner 2 and the gas stream enters by way of a hot top 5. The sand lining 2 may be made from a refractory sand such as silica sand, zircon sand, chromite sand, alumina, magnesia or a mixture thereof. The binding of the sand may be synthetic resin e.g. phenol resin, furan resin, urea resin, polyvinyl alcohol &c., organic material such as drying oil, cereals &c., organic acid, e.g. sodium alginate; or inorganic material, e.g. clay, sodium silicate, ethyl silicate, silicic acid gel &c.

Patent GB-323171-A (GB)
Abstract: 323,171. Henderson, J. B. June 29, 1917. Ordnance sights.-The line of collimation of a sighting telescope is kept parallel to the vertical plane through the axis of a gun on a ship, while the ship rolls, by means of an auxiliary sight which is at right-angles to the main sight and is maintained horizontal by keeping it sighted on the horizon or by any other means such as a bi-prism optical level or a gyroscopic pendulum. As shown in Fig. 1, an auxiliary sight comprising a peep sight 12 and a foresight 13 on a bar 11 is mounted in a slide 14a pivoted at 14 to another slide 15 on a bar 16, which is mounted on pillars 18 on a bracket 1 attached to a main sight (not shown). A box 2 also mounted on the bracket 1 contains a differential gear comprising a shaft 6 with a pinion 5 operated by a hand-wheel 7 with a pinion 3 to apply deflection to the main sight. The planet pinions 4 are carried by a spur pinion 9 in mesh with a rack 8 pivoted at 10 to the auxiliary sight-bar 11, which is at right-angles to the main sight. The slide 15 is adjusted along the bar 16 to a scale reading corresponding to the tangent elevation of the gun or to range, with the result that when the auxiliary sight is kept on the horizon while the ship rolls, the rack 8 moves and applies the necessary correction to the shaft 6 through the differential gear. In a modification, the rack is in the form of a screw attached to the bar 11 by a ball joint, and the deflection is applied to a director sight by a rotation of the rack, and the correction by the longitudinal movement of the rack. In another modification, Fig. 5, two sights 35, 36 are carried by a tripod 34 through the intermediary of a support 35 rotatable about a vertical pivot 39 and having a radial arm 40 fitted with a sector 49 which is formed with a groove and is rotatably adjusted about the axis of the arm 40 to incline the groove in accordance with the elevation of the sight 36 by a parallel link connection 52 therewith. A frame 41 is pivoted on horizontal trunnions 44 on the support and has a roller in engagement with the groove in the sector 49. The frame 41 is connected by a linkwork 67 to the mirror 57 of a periscope 56; and the frame is moved by the, shortening or lengthening of a telescopic link 54 by means of a hand-wheel 55, so as to maintain the horizon in the optical line of the periscope. The movement of the frame 41 causes the necessary deflection correction to the position of the support 35 about the axis of the vertical pivot 39, by the movement of the roller of the frame in the inclined groove in the sector 49.
