Title: Improvements in or relating to the sealing of glass sleeves on to wires
Inventor: SMYTH JOHN ARUNDEL
IPC: C03C27/04
Filed: 1953-10-14
Abstract: 725,785. Leading-in wires for electric discharge devices &c. STANDARD TELEPHONES & CABLES, Ltd. Oct. 14, 1953, No. 28266/53. Class 39 (2). Apparatus for sealing glass sleeves on to wires to facilitate the sealing of the latter through the envelopes of electric discharge devices, comprises a conveyer with means thereon for receiving a succession of wires which are first heated to produce an oxide layer on the part to which the glass sleeve is to be sealed, after which the sleeve is positioned over the said part and passed through a series of flames which heat it progressively from end to end. In the example the apparatus consists of a wheel 1 rotatable in intermittent steps about a horizontal axis 2 and provided around its periphery with a series of equally spaced radial holes 3 into which the leading-in wires 4 are inserted at a loading station. From the loading station the wire is carried through a slot in an arcuate plate 6 which is concentric with the wheel 1, and the part of the wire between the plate and the periphery of the wheel is heated by a series of oxidizing flames 8. During this. period a glass sleeve 7 is threaded over that part of the wire beyond the plate 6. When the wire 4 passes beyond the end of the slot in the said plate the glass sleeve slides down into contact with the edge of the wheel and is carried through the flames of an arcuate burner 9 so arranged that the flames play first at the upper end of the sleeve and then pass gradually down to the lower end, thereby driving all air out from the seal and causing the glass to melt on to the wire from one end to the other. On passing beyond the flames from the burner 9 the glass sleeve is allowed to cool slightly and then passed through the flames of a further burner 10 to cause slightly more of the oxide on the wire to be absorbed into the glass. As the wheel continues to rotate, the glass coated wires fall from the holes 3. The wheel comprising the conveyer may be mounted on a vertical axis so that it rotates in a horizontal plane. Alternatively the conveyer may be of the belt type.

Abstract: 668,216. Lap-forming apparatus. DICK CO., A. B. Nov. 7,1949, No. 28502/49. Class 120(i) [Also in Group VIII] A lap is formed by passing fibres entrained in a gaseous medium through. a first foraminous wall for deposition on a second foraminous wall arranged close to it, by means being present for preventing accumulation of fibres on the first wall. In the embodiment described, air is circulated in ducts 11, 12 by a fan 10, the fibres being fed in by means 30. The fibres are separated and prevented. from accumulating on the first wall 16 by blades 18 of a rotary disintegrator and pass through the wall 16 on to the second wall, a moving screen 21, to form the lap. Air is vented from the duct 11 at 28 so as to cause a slight inflow of air into the system in the region of lap formation. This may be achieved alternatively by having separate fans in separate blower and suction ducts operating at different outputs. Shutters 32 may vary the quantity of deposited fibres in position across the wall 21 and equivalent means may be provided at the entrance to the duct 12. Adhesives may be included in or sprayed on the fibres to form, felt-like structures or boards. A number of fibre depositing systems as described may lay fibre on a single screen such as 21, as described in Specification 668,217.

Title: Improvements in or relating to turbine power plant for transmission systems
Inventor: CLARK NEIL MILLIGAN
IPC: B63H23/00
Filed: 1959-08-20
Abstract: 929,237. Turbine-reversing gear. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Aug. 12, 1960 [Aug. 20, 1959], No. 28518/59. Class 110 (3). A turbine plant, including a forward propulsion turbine 1 and a reverse propulsion turbine 3, the forward turbine normally rotating independently of the reverse turbine, has means to accelerate the reverse turbine in the same rotational direction as that of the forward turbine, a clutch arrangement la, 3a operable to establish a driving connection between the two turbines 1, 3, when their rotational speeds have been substantially synchronized and valve-controlled duct means operable to transfer working fluid from the forward turbine 1 to the reverse turbine 3 to change the rotational direction of the latter. A free piston gas generator 17 supplies working fluid through a proportioning valve 13 to either of the turbines 1, 3. A control console 18 controls the valve 13 through an oil line 20, the rate of fuel flow to the gas generator 17 through a line 22. an auxiliary valve 11 and a clutch-locking mechanism 21a through lines 23, 24, respectively. A control arm 19 on the console 18 is rotatable from a point C (full ahead) to a point F (full astern) as shown in Fig. 3. From the stop position A to the position B the gas producer 17 is idling and the proportioning valve 13 moves so as to increase the supply of working fluid to the turbine 1. The fuel supply is then progressively increased as the lever 19 travels to the point C. As the lever 19 is brought back at the position D the clutch lock mechanism is energized and the auxiliary valve diverts working fluid to the astern turbine 3 through an auxiliary nozzle 8 to rotate it in the ahead direction. As the turbine speeds synchronize, the clutch engages and is locked in engagement, whereupon the working fluid supply to the astern turbine is shut-off. Movement of the lever 19 to the position E moves the proportioning valve 13 so that working fluid is supplied to the astern turbine 3 through the nozzle 7. Beyond the point E, the working fluid supply to the astern turbine 3 is increased. Alternatively, the radial astern turbine 3 may be replaced by an axialflow turbine in which case the auxiliary inlet 8 is not fitted. A fluid coupling, which may be associated with a friction clutch, can replace the clutch 1a, 3a. The fluid coupling is charged while the control lever 19 is in the range B-F (Fig. 3), and drained while the lever travels clockwise from B to C. When the lever 19 travels anti-clockwise the coupling is charged at the position H and the reverse turbine is rotated. As the turbine speeds synchronize, the friction clutch is engaged.

Abstract: 214,561. Jackson, P. R., (Sperry Gyroscope Co.). Oct. 11, 1922, Automatic steering-gear.- Automatic steering mechanism for ships, aircraft, torpedoes and the like comprising a course control device, an auxiliary control device responsive to changes in direction of the craft, means interconnecting the controls and a steering engine is provided with means whereby the auxiliary control operates to reverse the engine before the craft reaches its course. The apparatus can be set to swing the ship into any particular course. The compass card 10 and indicator 11, Fig. 3, are rotated by a repeater motor 13 through suitable gears to which is also geared the handle 30 for setting a new course. Fixed to the gear 32 is a trolly 50 having three contacts 68, 69, 70 adapted to engage contact strips 51, 52, 71 - - 74, Fig. 4, and a separate contact 76. An auxiliary control 25 comprises brushes 26 - - 29 controlled by a lever 47 from a repeater motor 39 which has a commutator with two segments 43, 44. In a slight clockwise yawing motion, the brush 28 engages contact 44 and a circuit is established through main lead 140, contacts 69 and 76, brush 28, contact 44, and relays 80, 81, 82 to the field coil 83 of a steering motor 84 to put the rudder 46 over. The rudder has a block 85 which closes the contact 86, when the rudder moves, to energize the relay 80 and thus break the circuit in the field coil 83. The rudder is then held until the ship has swung so far back on its course that the brush 29 contacts with the segment 44 and establishes a circuit which rotates the motor in the opposite direction and thus puts the rudder over to retard the final swing of the ship into its course. When a, large deviation of the ship occurs, the contact 68 establishes a circuit and the rudder is swung over. As the ship returns to its course the brush 26 moves off the contact 43 and the brush 29 establishes a circuit which puts back the rudder slightly beyond the centre to check the momentum of the ship. For changing the course, the handle 30 is rotated to move the rudder, the auxiliary circuit being established at the end of the movement as in the above cases. An alarm 98, is in circuit with the trolly 50 and contacts 71 so that it is sounded when unusually large deviations occur. The motor 84 may control a telemotor gear by means of a pinion 111 112, 113 and plungers in the cylinders 114, 113. the fluid in the system pipes 116, 117 in turn operating plungers in cylinders 120, 121 and this the sector 122. The motor 84 is of the series type, the speed of which may be controlled by a relay 125. When the automatic control is not required the motor 84 is declutched and a hand wheel geared in. Specification 135,871 is referred to.
