IPC: F04C18/12
Filed: 1927-12-19
Abstract: 282,752. Kozousek, J. Dec. 30, 1926, [Convention date]. Movable-abutment type; compensating for irregularity of flow; back-pressure, reducing.-Rootsblower type pump impellers are so constructed that the maximum working space, for any given number of teeth or lobes is obtained and the impellers can be made by the rolling-off method. Fig. 5 is a diagram showing the volume of the working space as a percentage of the cylinder volume for different numbers of teeth z = 2, 3, 4, the teeth being of involute form with varying angles of engagement. For an impeller with two teeth, for example, a maximum working space 59.5 per cent of the cylinder volume is obtained with an angle of engagement 47‹ 40. With teeth of cycloidal form the generating circle should be half the pitch circle, the flanks of the teeth then being straight lines. -With two teeth the working space is 63 per cent of the cylinder volume. The teeth may be slightly truncated for sealing purposes and the impellers may be made with inclined teeth. To reduce back pressure at the meshing point a recess 8 may be provided in the casing or the roots of the teeth may be hollowed out at 9. To compensate for irregularity in flow, due to the sudden opening of a pocket to the delivery pressure, the casing is cut away at 1<1>, or a duct 10 leading to the delivery pipe is provided, or an air chamber 11 may be formed in the casing. The impeller shafts are connected by gear wheels which are adjustably fixed on the shafts by key members 14, Fig. 7, which are divided along an inclined line and adjusted by a nut 15.

In a steering gear arrangement for a tracklaying vehicle one axle 4a, Fig. 3, is positively driven from the driving shaft 1 while the other 4b may be connected to the axle 4a so that it is fast in rotation therewith or may be caused to rotate in the reverse direction. The shaft 1 has a bevel gear 2 in mesh with a bevel gear 3 on the axle 4a which has a toothed ring 20 connected by a coupling sleeve 15 to a ring 16 fast with the axle 4b so that the two axles are rigidly connected when the vehicle is to travel straight ahead; a bevel gear 13 in mesh with the bevel gear 3 turns freely on the axle 4b. To cause the vehicle to make a pivot turn, the sleeve 15 is disengaged from the ring 20 by a fork 22 and is engaged with a similar ring 21 fast with the bevel gear 13 so that the latter imparts a reverse drive to the axle 4b. Means may be provided to synchronize the parts to be coupled. Fig. 3 shows an alternative construction in which the sun gear 3<SP>1</SP> of an epicyclic gear is fast with the axle 4a, the planet carrier 23 is rotatable on the axle 4a and the annular gear 26 is fast with the axle 4b. A clutch member 27 locks the planet carrier 23 to the annular gear 26 so that the epicyclic gear becomes a rigid system when the axles are to be rotated in the same direction. Reverse rotation is imparted to the axle 4b by braking the planet carrier 23.

Abstract: 820,771. Jet propulsion plant. UNITED AIRCRAFT CORPORATION. Nov. 12, 1957 [Nov. 21, 1956], No. 35205/57. Class 110 (3). [Also in Group XXXIII] Jet propulsion engine thrust reversal mechanism comprises two sets of rotatable units pivotally mounted on the exhaust duct, and means to rotate the units between a retracted position in which they form a smooth fairing outboard of the duct, and a thrust reversal position in which the units form two abutting substantially semicircular passages downstream of the duct, to divide the exhaust gas into two streams each deflected in two substantially equal stages and discharged in a direction to give a reversed thrust. Fig. 2 shows in plan a gas turbine engine 10 discharging through a nozzle 20. A member 50, which in the retracted position shown in full lines has a semicircular cross-section perpendicular to the nozzle axis, is pivoted at two nearly diametrically opposite pivots 52 to brackets 126 on beams 68, the upper pivot, bracket and beam being shown. Each beam is secured to an engine supporting ring 104, an engine flange 114, and an I-section ring 116 surrounding but not attached to the nozzle 20. A member 48, also of semicircular section is pivoted to member 50 at two pivots 54 (the upper one shown), and has pivots 58 connected to the piston rods 62 of jacks 64 universally mounted to the engine at 80, and connected to tie rods 60 pivoted at 90 to brackets 66 on beams 68, the upper pivot 58, jack 64, rod 60 and bracket 66 being shown, those on the underside of the engine being similar. The other side of the engine is similarly provided with members 501, 48<1>, jacks 64<1>, and tie rods 60<1>. Meshing gears 76, 76<1> on pivots 52, 52<1> ensure equal operation of members 50, 50<1>. The jacks 64, 64<1> are operated by fluid pressure control of conduits 86, 88. Extension of the jacks rotates members 50, 50<1> to abut on surfaces 92, Fig. 3, and imparts a compound motion to members 48, 48<1>. These members have reinforcing brackets 98, 98<1>, and members 50, 50<1> have reinforcing brackets 100, 100<1> which in the thrust reversal position of Fig. 3 abut members 48, 48<1> at surfaces 94, 941 to provide a seal. In the thrust reversal position, the angle that members 50 and 50<1> make with the engine axis equals that between members 50 and 48 or 501 and 48<1>, and the exhaust gases are deflected through a total angle of 135 degrees. Spring-loaded locking latches 46, Fig. 2, engage members 48, 48<1> so that a pilot desiring thrust reversal must release the latches, which are fluid-pressure operated, before commencing movement of jacks 64, 64<1>. On retracting members 48, 48<1> to the normal position, the latches automatically re-engage.
