Rotors.-In a radial flow turbine, the blade carrying discs are formed as annular elements as described in Specification 6104/09, and are connected together by bolts which are wholly or partly hollow. The object is to prevent deformation owing to temperature changes. Fig. 2 shows the application to one rotor of a combined-flow turbine of the oppositely-running rotor type. The elements 21, 22 carrying the inner ring of radial-flow blades, and the outer element 23 carrying the outer rings of radial-flow blades, and also the ring or axial-flow blades, are connected by hollow bolts 26 which pass through registering holes. The bolts are larger than the holes and must be forced in when the parts are cold, but they permit of some radial play when the parts are hot. Radial displacement of the bolts is prevented by stops 28, 31, or by other means. The sections of the bolts outside the holes may be of reduced diameter, and the bolts may have grooves 32 which may be filled with lubricant. A passage 24 is provided for drawing off or admitting driving fluid. A modification, in which two annular elements are connected, is described.

Title: Plate glass polishing apparatus
IPC: B24B7/24
Filed: 1957-04-02
Abstract: 825,099. Polishing plate glass. PITTSBURGH PLATE GLASS CO. April 2, 1957 ]April 2, 1956], No. 10697/57. Class 60. [Also in Group XXXVI] An apparatus for polishing plate glass G, Fig. 1, comprises means for moving the glass along a horizontal plane relative to a fixed support structure 68 carrying a vertically - adjustable polishing apparatus in the form of a runner 80 driven by a motor 64, and switch means arranged in circuit with the motor and provided with contacts 112, Figs. 2 and 4, which are carried by a support movable in unison with the runner and are vertically aligned relative to contacts 102 coupled electrically to a source of power, at least one of the contacts being resilient, whereby the aligned switch contacts are urged into contact to permit closing an electrical circuit controlling the motor when the motor and polishing apparatus are installed on the structure. The glass is carried on cars C, Fig. 1, past the polishing runners 80 which are felt-faced and mounted on freely-rotatable shafts 78 on arms 77 attached to a shaft 62 rotated by the motor 64 through gearing 66. The shaft is disposed within a tubular support 60 carried by trunnions 58, 76 engaged in the hook-shaped ends of levers 54, 70 pivoted to the fixed support bracket 68. The opposite end of the lever 54 is attached to a nut 36, which is adjustable to compensate for wear of the runners, as the piston rod 32 of a piston-and-cylinder device 22, so that fluid pressure controlled by valves 26, 28 from a tank 20 supplied to the top of the device 22 lifts the runners from engagement with the glass. When it is desired to remove or replace the runner assembly from the machine by a crane engaging the trunnions 58, a flange 172 cooperates, with the roller 170 of a limit switch L.S.1, which makes or breaks the circuit to. the motor before the switch contacts 102, 112, Figs. 2 and 4. The elements 112 are formed as copper rings in axial alignment within a steel cover 119 separated by insulators 114 and secured to a shaft 120 mounted on the gearing housing 66. Disposed vertically below the copper rings are the elements 102 formed as arcuate arms which are secured by bolts to springs 94 clamped to an insulated base 88 mounted on the lever 54. The rings 112 are connected by a cable 117 to the motor 64, and the arms 102 by a flexible conduit 106 to a cable 109. In operation, a start button 150, Fig. 1, can only energise the starter coil of the motor 64 when a limit switch LS1, which is actuated by a roller 180 contacting the lever 54, is closed ; the movement of the lever to bring the runners into contact with the glass opens the switch to break the starter coil circuit of the motor so that the motor cannot be started when the runners are in contact with the glass. A similar arrangement to that described may be used in combination with polishers for finishing both surfaces of the glass.

Title: Cooling arrangement for rotary piston machines
IPC: F02B55/10
Filed: 1961-03-27
Abstract: 926,417. Rotary l.C. engines. CURTISS-WRIGHT CORPORATION. March 27, 1961 [March 29, 1960], No. 11014/61. Class 110 (2). In a rotary I.C. engine of the n and n + 1 lobe type comprising, as shown, a three-lobed rotor 16, Fig. 1, eccentrically rotatable in a twolobed epitrochoid-shaped casing 12, the casing which is made up of end walls 22, 24, Fig. 3, and a peripheral wall 26 is provided with liquid coolant passages arranged in groups seriallyconnected so that the direction of flow of the coolant between the end walls reverses in flowing from one group of passages to the next. The end wall 24 formed with a hollow interior is provided with partitions 80, 82, 84, a coolant inlet 92 and a coolant outlet 94 whilst the end wall 22 which is also hollow has partitions 96, 98. Coolant from the inlet 92 passes through a group of openings 104 between the partitions 80, 82, aligned passages 106 in the peripheral wall 26 and openings 108 in the wall 22. The coolant then reverses its direction of flow passes through a group of openings 110, aligned passages 112 and openings 114. The coolant is again reversed passing through openings 116, aligned passages 118 and openings 120 and finally passes to the outlet 94 through openings 136, aligned passages 124 and openings 126. In an I.C. engine since the phases of the operating cycle always occur at the same locations in the casing, some parts of the casing receive a higher heat input than others and in order to avoid uneven expansion of the casing with consequential internal stresses the groups of passages are of differing " hydraulic diameter," i.e. crosssectional area divided by perimeter. In the region of the combustion chamber where the spark-plug 44 (or injection nozzle) is located and the heat input to the casing is high the hydraulic diameter is relatively small resulting in increased flow velocity with enhanced cooling. In the vicinity of the inlet 40 where the combustion air or gases enter the engine and heat input to the casing is low the " hydraulic diameter " is relatively large. In this locality the slower moving coolant allows the casing to give up some of its heat to the incoming air or gas to assist in vaporizing the fuel. Between these two extremes the " hydraulic diameter" progressively varies. Two engine units may be connected to the same shaft with the liquid coolant to the two units being supplied in parallel from a common source.

[Also in Division G3] In a fuel injection pump in which the fuel pressure varies in accordance with the driven speed and in which the flow from the feed pump to the injection pump cylinder is controlled by a throttle, the throttle is angularly movable by hand or by a governor and axially movable against resilient means by the feed pressure. The throttle valve 30 has an arm 33 connected for angular adjustment to a governor arm 35. The arm 33 also carries an abutment 46 having a cam surface 49 engageable with an adjustable stop 48 when the governor sets the valve 30 to provide maximum fuel, such that axial movement of the valve 30 in accordance with feed pressure (and hence engine speed) will vary the angular setting of the valve and hence the quantity delivered. The valve 30 has an additional port (51, Fig.4 not shown) which when the pump is stationary registers with the fuel inlet 32 to provide excess fuel for starting. The valve is loaded by a weak spring 45, which allows the valve to rise on starting, and a working spring 44.
