[Class 38 (iii).] To start a motor, voltages below normal, above normal, below normal, and normal, are applied to the armature winding in succession. Upon closure of a switch 10 a switch 4 is closed which connects the motor 1 to the supply with part of the windings of an autotransformer 2 acting as a series choke. After a time interval a relay 13 closes to close a switch 3, so that the motor is supplied with a voltage above normal. After a further time a relay 16 opens its contacts 17 and closes its contacts 18, so that the relay 13 and switch 3 open, and the initial motor connections are re-established. Upon opening of the switch 3 a switch 7 is closed to connect the motor directly to the supply. A field switch 9 is closed when a centrifugally operated switch 21 closes, provided that the switch 7 has been closed. The switch 9 may close independently of the switch 7, and may have auxiliary contacts in the circuit of the coil of the relay 16, so that it must close before the abnormal voltage is applied.

Title: Improvements in ammunition hoists especially suitable for use on board ship
IPC: F41A9/07
Filed: 1922-11-29
Abstract: 211,958. Armstrong, Whitworth, & Co., Ltd., Sir W. G., Lee, H. W., and Swindale, J. W. Nov. 29, 1922. Loading-appliances. - Ratchet ammunition hoists of the kind described in Specifications 143,336, 169,748, and 173,029 are rendered flash-tight whilst the ammunition is being delivered from or supplied to the hoist, by providing at the top or base of the hoist a cylindrical ammunition receptacle 13 which rotates in a frame 14 when the frame is traversed into or out of the hoist. In the form shown in Fig. 1, the projectiles P are raised into the receptacle 13 at the top of the hoist by pawls. 11 rocking on sliding bars 10. The receptacle 13 is vertically pivoted in the frame 14 which is traversed to the right by bell-crank levers 18 in the arms 17 of which engage cam slots 101 in the sliders 10. The receptacle has a toothed sector 132 which engages a fixed rack 151 to rotate the receptacle in a flash-tight manner through 180‹. The projectile is thus presented to the outside of the hoist and is received on a tray 31 which is rocked into the vertical position by a bellcrank lever 33 operated by a slot 102 in the slider 10. During continued movement of the slider, the tray 31 carries the projectile into the horizontal position for delivery, the frame 14 is returned to the hoist, and the receptacle 13 grips another projectile by means of pivoted spring catches 21, Fig. 7. These catches are interconnected by links 27, 29, Fig. 9, which are automatically rocked by engagement with a fixed finger 25 to release the catches when the cylinder 13 is turned away from the hoist. If the ammunition is to be passed into the hoist, a hand-lever 23 is operated to bring an alternative finger 25<1> into operation, the first then passing out of action. When the cylinder 13 is out of the hoist, the next projectile is retained by guideplates 39 hinged to the hoist by links 40. Specification 212,502 also is referred to.

Patent GB-792235-A (GB)
Title: Process for the recovery of magnesium
IPC: C22B26/22
Filed: 1955-11-16
Abstract: Magnesium is produced by reacting a magnesium compound with an alkaline earth hydride at a temperature between 700 and 1600 DEG C. The hydride may be contaminated with considerable amounts of other substances such as alkaline earth metal carbides, silicides, oxides and nitrides and possibly carbon, iron and aluminium which contaminants may amount to ten times the weight of magnesium present. The magnesium compounds used may be be the chloride, sulphide or phosphide, but preferably the oxide is used and may be admixed with other oxides.  The process is preferably carried out in two stages in the first of which only a part of the magnesium and substantially all the hydrogen is withdrawn as vapour from the reaction mixture under a partial pressure of hydrogen higher than the magnesium vapour pressure, and in the second of which the residual magnesium is vaporized at a lower pressure or higher temperature.  Additional hydrogen may be led through the reaction zone during the process. Specification 792,017 [Group III] is referred to.

Title: Sealing device, especially for regenerative heat exchanger
IPC: F16J15/34
Filed: 1963-08-20
Abstract: 1,063,984. Mechanical seals; pipe Joints. SVENSKA ROTOR MASKINER A.B. Aug. 20, 1963 [Aug. 20, 1962], No. 32857/63. Headings F2B and F2G. [Also in Division F4] The seal 15, Fig. 1, for a rotary heat-exchanger comprises a sealing ring 18, Fig. 2, which is carried by a yielding sleeve 20 and pressed against, or held at a small distance from, a counter sealing ring 17, and means 21, 22 for relieving the sleeve of peripherally-directed forces. The ring 18, which may be made in one or more parts and formed with grooves on its sealin face is prevented from turning relative to the flange 19 by bolts 21 which are slidablymounted in tubes 22, a clearance being provided around the bolts to permit radial as well as axial movement. As shown, flue gases are directed through a heat-retaining stator 1 via ducts 2, 3 while combustion air is directed through the stator via stationary ducts 4, 7 and rotary interconnecting-ducts 5, 6 which are secured to gear rings 11, 12 driven through gears 8, 9 by a motor 10. The sleeve may be made of asbestos strips, metal cloth or interconnecting spring plates; guide plates 23 prevent damage to the cloth on flexing. The sealing rings, which may be made of sintered materials, are urged towards each other by virtue of their own weight; springs may be employed if the heat exchanger is arranged horizontally. If contact-free sealing is preferred to sliding friction, the sealing ring may be held away from the counter sealing ring by levers and be guided in accordance with the warping; spring or fluid pressures may be used to guide the sealing rings. Instead of bolts 21, projections and notches may be employed. The seal 16 between the rotary duct 6 and stationary duct 7 is similar to seal 15 except that the flexibly-mounted ring 18 rotates and the ring 17 is stationary.

Title: Automatic tile presses
IPC: B28B17/00
Filed: 1952-12-29
Abstract: 707,960. Machines for moulding tiles. DUBIOS. F., DUBIOS, W., and DUBIOS, M., [trading as DUBIOS & CO.]. Dec. 29, 1952 [Dec. 29, 1951], No. 32901/52. Class 87 (2) A tile press comprises a mould 10, an upper pressing die 3 carried by a vertically-reciprocating ram 1, and a lower die 11 secured to a tileejecting rod 12. A pair of spaced parallel tie rods 4 are secured to the ram and extend downwardly through the press table 5, these rods carrying at their lower ends a crosshead 7 provided with means for lifting the rod 12 and with a vertically-disposed toothed rack 37 which engages toothed gearing 46 ... 49 adapted to actuate rocking levers 51 connected with the filling slide 38 for imparting the required horizontal reciprocating movement to the .slide. Thus, as the ram ascends after pressing a tile it lifts the crosshead 7 by way of rods 4, and thereby lifts rod 12 and lower die 11 to eject the pressed tile, and at the same time the rack 37 is lifted to move the slide 38 to the left, Fig. 2, to push off the pressed tile and fill the mould. The ejecting rod 12 is slidably mounted in crosshead 7 and carries rollers 17 which rest on levers 22 fulcrummed on a fixed shaft 23. Levers 21 also are fulcrummed on shaft 23 and are clutched by their hubs, at 25, to the hubs of levers 22. When the ram 1 begins to rise the levers are clutched together, springs 26 keeping the clutches in engagement, and rollers 18 mounted on the crosshead tilt the locked levers counterclockwise, Fig. 2, about 23, so that levers 22 raise rod 12; but when the filling slide is above the mould, a wedge 28 on the crosshead forces apart levers 21 (Fig. 1), so disengaging the clutches, whereupon the levers 22, rod 12 and die 11 fall to their lowermost position, thus allowing the filling material to fall into the mould. When the ram descends the levers resume their clutched position. The rod 12 is in two parts secured together by screw 14, whereby one part may be withdrawn upwardly and' one downwardly. To vary the thickness of the tile being pressed, the plate 24 which supports levers 20, 22 may be raised or lowered. The slide 38 moves on ball bearings which run in V-ways in a base 40 supported by a post 41 vertically adjustable in table 5. When the dies are to be cleaned or repaired, the ram is raised above its normal uppermost position, and this excess movement disengages a clutch on shaft 50, so that the slide may be withdrawn. Buffers 59 absorb the impact of the returning slide.

Title: Improvements in or relating to apparatus for starting up vapour power plants
IPC: F22B35/14
Filed: 1965-08-03
Abstract: 1,089,056. Raising steam in forced flow once through boilers. BABCOCK & WILCOX CO. Aug. 3, 1965 [Aug. 4, 1964], No. 33160/65. Heading F4A. A vapour power plant comprises a oncethrough forced flow vapour generator 14, having an economizer 16, vapour generating section 17 and superheater 18 connected in series, a turbine 22, a condenser 31, condensate pump 33, low pressure feed water heater 36, de-aerator 37, feed pump 10, and high pressure feed water heater 12. On start up a quarter full load water flow is established through feed pump 10, heater 12, economizer 16, vapour generating section 17 and conduit 39 to flash tank 42, valves 21, 48, 50 and 60 being closed so that no steam can enter the superheating  section 18, the valve 41 maintaining full load pressure at the outlet of vapour generating section 17. Water from flash tank 42 flows through conduit 49 to de-aerator 37 and so back to the feed pump 10. Firing is commenced and as the deaerator and flash tank pressures rise to 20 p.s.i.a. valve 51 starts to close, controlling the de-aerator pressure and valve 70 in line 65 begins to control the flash tank water level by passing the flash tank condensate to the shell of heater 12 and then to the condenser 31 through conduit 71. Consult 52 and valve 53 pass any excess flash tank water direct to the condenser 31. Steam flashing in tank 42 passes via line 59 to seal the turbine, then as the pressure increases also via conduits 54 and 57 to the deaerator 37 and high pressure heater 12. Flash steam is next passed at a pressure of 150 p.s.i.a. upwards' through conduit 45 and superheater 18 and round turbine by-pass line 43 to the Condenser 31, the flow being diverted through the turbine 22 for. rolling when suitable flash steam conditions are reached. This is facilitated by tempering the superheater outlet steam with saturated steam from flash tank 42 which bypasses superheater 18, through valved conduit , 65. Similarly the steam flow from reheater 76 to the low pressure part of turbine 22 may be tempered by saturated steam from flash tank 42 supplied through valved conduit 78. Turbine steam control at this stage is effected on valve 25 with valve 24 closed and valve 26 open. The turbine load is increased from 2 to 10% full load by closing the turbine by-pass valve 44, and then to 20% full load by increasing the firing rate, valves 50, 60 and 79 in conduits from the flash tank being closed as valve 48 in by-pass conduit 47 is opened. When valve 48 is full open, valve 41 closes and all steam from vapour generating section 17 flows directly to superheater 18 to pass to the turbine. As the by-pass system steam pressure decays turbine extraction flows take over the deaeration and feed water heating. As the load is brought up to its full value valve 21 is opened and valve 48 closed and turbine control is transferred from valve 25 to valve 26, valve 24 being fully open. During start up any excess flash steam is passed direct to the condenser 31 through conduit 62.
