Filed: 1969-06-13
Abstract: 1276871 Counter-rotating rotors of rotorcraft UNITED AIRCRAFT CORP 13 June 1969 [17 July 1968] 30133/69 Headings B7G and B7W Cyclic pitch changes of the blades 19, 21 of respective counter-rotating rotors 12, 14 of a rotorcraft, the topmost of which rotors rotates anticlockwise are controlled by respective swash plates 24, 26 which in turn are controlled for deflection about axes 92, 88 and 94, 90 respectively by rods 44, 46 and 48, 50 respectively, the blade horns 32, 40 respectively being connected by the rods 34, 42 to respective swash plates at points angularly offset in the directions of rotation of the respective blades from the blade axes 20, 22 when the blade axes are aligned with either rods 44, 48 or 46, 50 respectively, the effect of the offset connection being such that during roll motion a proportion of pitch motion is introduced to counteract gyroscopic precession, and that during pitch motion a similar proportion of roll motion is introduced for the same reason. Motion of rod 44 is caused by left/right motion of the manoeuvre stick 52 by way of connecting rods 70, 74 and 78 and bellcranks 72, 76 and 80. Similar motion of rod 48 is caused by bellcrank 82. Motion of the rods 46, 50 is caused by fore/ aft motion of the manoeuvre stick 52 by way of connecting rods 60, 64 and bellcranks 58, 62. Trim levers 54 and 56 are provided so that adjustments in trim can be made to "centre" the manoeuvre stick before each flight. Levers 54 and 56 are coupled by rod 98 so that the pitch trim lever 56 introduces a proportion of roll trim and roll trim lever 54 introduces a proportion of pitch, the proportions being predetermined and fixed by the spacings of the various connections on the rod 98. Rather than by offsetting the blades, pitch and roll movements to counteract gyroscopic precession may be derived from additional lifting surfaces on the rotorcraft or by mechanical means interposed between rods 84 and 48, 86 and 44, 66 and 46, 68 and 50 respectively.

Abstract: 967,799. Reverse gear; control; lubricating; casings. BORG-WARNER CORPORATION. Aug. 21, 1961 [Aug. 29, 1960], No. 30134/61. Heading F2D. To reduce or eliminate pump cavitation due to foaming in an hydraulically controlled marine, forward-neutral-reverse, epicyclic gear, the sump 20b is inclined upwardly from front to back at approximately 18 degrees to the gear axis thereby reducing fluid level by providing a horizontal-bottomed sump when the gear is mounted in its operating position, a unitary resilient steel sheet baffle plate 19 is snapped into position in the housing 20 to provide a part-cylindrical gear compartment separated from the sump, and returned fluid is connected directly to the pump intake 48 by a screened, tubular member 54 passing through the sump. The forward-neutral-reverse epicyclic gear comprises interengaging planets 24, 23 on an output carrier and respectively meshing an input sun 22 and a ring 21 which may be friction clutched at 14 to the sun for locked-up forward drive or friction braked at 16 for reverse drive at the same speed as forward. The clutch 14 is multiplate and is actuated by an hydraulic servomotor 15 acting through a Belleville washer lever 35 and the brake 16 is actuated directly by an hydraulic servomotor 17. The control system comprises an input gear pump 18 delivering to a combined distributer and pressure regulator valve 50, and a cooler 52. The valve 50 comprises a rotary member 56 having a bore 58 which receives fluid from the pump through an annulus 63 and radial bores 64, selectively actuates and exhausts the forward and reverse servomotors, and, when the pressure reaches a predetermined level to axially move a spring-loaded piston 61, allows fluid flow to the cooler and a gear and bearing lubrication line 66 through ports 67 and 65 in communication therewith in all shift positions of the valve. The tubular member 54, comprising a hollow tube 69 and a cylindrical screen 70 fixed thereto, prevents cavitation in the pump due to entry of foam or air during high-speed turns. The baffle 19 is formed with a radius larger than the housing 20 in order that it may be snapped into position and held by housing bosses engaging rectangular holes therein. The sump slope permits the engine and gear to be installed lower and further to the rear.

The contact element 26 is held in vertical grooves in abutments 24, integrally formed with the member 12, and by the engagement of barbs 27 in the abutments. The spacing between the legs 29 of the element is slightly less than the smallest wire diameter so that the wires are pressed into the recesses 31 by fingers positioned between the beams 52, resulting in piercing of the wire insulation and spring retention of the bared conductor. Members 34 are formed integrally with the body 12 and have resilient fingers 37 of width slightly less than the smallest wire diameter, the slots in the closed position of the connector being in line with the bores 48 and 49 and thus acting to grip the wires. The bore 49 terminates within the end wall 46, a deflection plate bending the end of the wire over. The beams 52 are spaced to fit in the gaps between the contact element 26 and the wire supports 34. Between each beam 52 and the adjacent end wall 46 or 47, are posts 57 to force the wires into slots 35 in the wire supports 34. The latching members are such that from the open position, Fig. 3, the connector can be partially closed, by finger pressure, to a position in which the end of the ramp surfaces 58 engage the centres of the projections 40, the sides of the member 12 being outwardly splayed. In this position with the wires partially retained, a tool may be substituted for the finger grip, to completely close the connector. One or both of the members 10 and 12 may be of a transparent material and a transparent dielectric grease may be inserted around the contact element. Actual dimensions of one embodiment of the invention are given.
