Title: Improvements in reusable locking means for turbine or compressor rotor assemblies
IPC: F01D5/30
Filed: 1961-02-14
Abstract: 894,704. Turbine and compressor blade mounting. GENERAL ELECTRIC CO. Feb. 14, 1961 [March 30, 1960], No. 5417/61. Class 110 (3). In a turbine or compressor rotor assembly in which the blade roots are received in slots extending transversely across and through the rotor rim, the blade roots are prevented from sliding in the slots by means of an expansible snap-ring removably seated in a continuous annular groove opening radially inwardly and formed partly in the radially inner surface of the rotor rim and partly in the blade roots. The fir-tree roots 4 of the rotor blades 2 are mounted in correspondingly-shaped slots 13 extending across the rotor rim 10. The blades are restrained from sliding along the slots by means of a snap-ring 18, as of spring steel, which is inserted into a radially inwardly facing annular groove which is formed partly by an interrupted annular groove 15 in the rotor rim and partly by arcuate grooves 7 in the blade roots. The snap-ring 18 is interrupted at a gap 19 and one end is preferably formed with a tab 20 by which it can be grasped during insertion or removal. Tab 20 engages a notch 21 to prevent the gap 19 from rotating into a position within a slot 13. The snap-ring 18 is inserted into the grooves 7, 15 after the blades have been inserted into the slots 13. Alternatively, if the snap-ring 18 is sufficiently flexible, it may be inserted in groove 15 before insertion of the blades, the subsequent insertion of each blade into its slot 13 causing the root 4 to locally press the snapring radially inwards until the snap-ring snaps into the groove 7.

Title: Apparatus for sampling liquids
IPC: G01N1/14
Filed: 1973-02-02
Abstract: 1361161 Sampling apparatus E SINGER 2 Feb 1973 [3 Feb 1972] 5423/73 Heading B8N [Also in Division F1] Apparatus for taking measured samples of liquids comprises a closed metering chamber 18, a volume control tube 25 extending into the chamber and terminating at a lower end above the bottom of the chamber, a vacuum/pressure power source connected to the chamber near the top of the chamber, control means for causing the source alternately to apply suction to the chamber for drawing liquid to be sampled into the chamber through the tube 25, and fluid pressure to the chamber for blowing out the tube to clear any blockages, and a liquid level controller. The controller is operative when the liquid drawn into the chamber 18 reaches a predetermined level above the lower end of the tube 25 to cause the application of suction to the chamber to be discontinued and fluid pressure to be applied for forcing liquid out of the chamber through the tube 25 until the level of the liquid in the chamber drops to said lower end. In one embodiment the pressure and suction sides of a pump 56, Fig. 3, are connected respectively via solenoid valves 50, 49 to a conduit 47, 43 which enters the top of the chamber 18. The valves 49, 50 are controlled from a timer 80, Fig. 1, and the liquid level controller comprises a pair of electrodes 42 in the circuit of a purge timer 94.  In operation, the timer 80 is operated to cause alternate periods of pressure and suction to be applied to the chamber 18 to cause it to fill with liquid via a hose 31 and the tube 25. When the liquid level reaches the electrodes 42 the timer 94 overrides the timer 80 and first causes pressure to be applied to lower the liquid level to the bottom of the tube 25. A valve 39 is then opened and further pressure applied to discharge the measured sample via outlet 33 into a jar 36. The valve 39 is then closed and after a set time interval the cycle of operations is repeated. In a second embodiment the timer 80 is replaced by a control which is actuated by the pressure in the chamber 18. The tube 25 is vertically adjustable to vary the sample size.

Abstract: 554,903. Cupola &c. furnaces. FIFE, J. G. (Meehanite Metal Corporation). April 27, 1942, No. 5624. [Classes 51 (i) and 51 (ii)] Blast is supplied to the tuyeres 30, Fig. 2, of a cupola or like furnace through a chamber 22 in which means are provided to ensure that the blast which enters the upper part of the chamber through a pipe 23 shall enter the tuyeres at uniform velocity. In the furnace shown a partition 38 divides the chamber into upper and lower compartments and openings 40 in the partition are provided with rotary vaned resistors 42 mounted on spindles 41 passing through the upper end of the chamber 22 where they are provided with pinions 43 engaging with an annular gear wheel 44 to ensure that the resistors which are driven by the blast shall all rotate at the same velocity and equalize the blast supplied to the tuyeres. The pinions may be coupled by a sprocket chain and one of the spindles may be provided at its upper end with a fly wheel and braking device either mechanical or electrical. Instead of coupling the resistors together they may be independently mounted in brackets 73, Fig. 14, and the upper end of each spindle may be provided with a head 74 which makes frictional contact with the bracket. The resistors are retarded by friction to a greater extent where the pressure of blast is greater. The resistors may be arranged in two different planes with adjacent resistors overlapping. Friction may be applied to the spindles by bolts passing through the chamber casing and in a further modification springs may be arranged between the heads 74 and the brackets. In place of rotary vanes, the openings in the partition may be provided with pivoted flaps 62, Fig. 11, the spindles 63 of which carry arms 64 secured to a ring 65 encircling the blast chamber 22. The flaps 62 are opened by the blast against the resistance of springs 67 coupled to the ring 65 and to a projection 68 on the chamber 22. The coupling ring 65 may be dispensed with in which case each arm is adjustably attached to a spring secured to the chamber wall. The flaps 62 may be provided as shown in Fig. 13 with projections 71. In a further modification, shown in Fig. 20, the resistors may comprise fixed tubular members 39. Fig. 22 shows a modification in which the spindles 41 of the rotary vanes 42 are provided with dynamo electric machines 86 and one spindle is provided with a variable speed prime mover such as an electric motor 87. The rotors of the machines 86 are electrically interlocked to rotate in synchronism. Should the supply of blast to the chamber through the pipe 23 cease the resistors are driven by the machines 86 to supply the blast uniformly to the tuyeres. Specifications 532,887 and 546,169 are referred to.

Abstract: 478,094. Signalling-apparatus. MERCIER, J. Feb. 26, 1937, No. 5792. [Class 118 (ii)] - [Also in Group XXXIII] The connection between a transmitting unit and a fluid-transmission means is elastic during part of the travel of the transmitting unit and rigid for the remaining part. In Fig. 1, movement of the handle 1 is transmitted to the fluid transmission 9, 10 firstly by the compression spring 6. When the spring is so compressed that the end of tube 3 engages plate 5, the transmission becomes rigid thus ensuring an accurate final indication on indicator 11. A tensile transmitting unit is shown in Fig. 2, the initial movements of the handle 1 passing through the spring 6, and the final movement being transmitted by the rigid wire connection 13. The indicator unit in this embodiment provides for three indications. An initial' compression or tension may be given to the springs so that a rigid connection exists at the beginning as well as at the end of the movement. The invention is described for indicating to a pilot of an aircraft the position of a retractible undercarriage.
