Title: Improvements in vehicles adapted to carry material handling attachments
IPC: E02F9/20
Filed: 1960-04-14
Abstract: 871, 287. Motor vehicles. GENERAL MOTORS CORPORATION. April 14, 1960 [May 13, 1959], No. 13340/60. Addition to 819,954. Classes 79(3) and 79(5). A vehicle comprises a forward section which is equipped with a material handling attachment, e.g. a digger bucket, and which is articulated to the rear section about a vertical axis provided by ball-and-socket joints 26, 28 and about a longitudinal axis provided by ball-and-socket joints 26 and 30 as described in the parent Specification, the vehicle being rotated about the vertical axis for steering purposes by a pair of hydraulic jacks 32. The front and rear wheels of the vehicle are driven as in the parent Specification, and a follow up device is provided which is operative at a given angle of turn determined by the extent of turn of the steering wheel to stop the mechanism from turning the front section further, the follow up device being little affected by relative movements of the two sections about the longitudinal axis. A steering worm 36 is driven through splines 46 allowing axial movement of the worm, from a steering shaft 48. The worm is engaged by a follower 52 mounted on a crank 54 rigid with a shaft 56 with which a crank 58 is also rigid. A rod 62 is pin jointed to the crank 58 and to a member 29 of the front section to which parts of the ball-andsocket joints 28 and 30 are attached. Centering springs 44 are provided on the worm. A valve, having ports 76 and 78 communicating with the hydraulic cylinders 32, an exhaust port 68 connected with a tank 70 and an inlet port 72 connected with a pump 74, has a spool 86 moved axially by a link 92 in response to axial movements of the worm 36. At the commencement of a turn, the pivot points 28, 30 and 26 'are in the longitudinal vertical plane of the vehicle. The steering wheel is turned and because of the position of the follower 52 and its associated links prevents the follower-from moving, the worm moves axially in one direction. Because of the geometry of the mechanism, as the front section turns, the rod 62 causes the follower to move and thus the worm 36 in a direction opposite to which the worm has previously moved to the point at which the hydraulic system is inoperative. As shown in Fig. 4, the valve is in the inoperative position. When the spool moves downwards the inlet port 72 is opened to the port 76 leading to the cylinders 32 and return line 78 communicates with the return 68 through apertures 88 and a central bore of the spool. In the upper position, inlet port 72 is opened to port 78 and port 76 is connected to port 68. Because the rod 62 is close to the longitudinal axis of turn, relative movements of the sections about that axis do not substantially affect the follow up device.

Title: Dual area solid propellant rocket nozzle
IPC: F02K9/86
Filed: 1971-05-06
Abstract: 1480723 Solid fuel rockets: propulsion nozzles ROCKWELL INTERNATIONAL CORP 6 May 1971 13544/71 Heading F1J [Also in Divisions F3 and F4] A solid propellant rocket having boost and sustain grains is provided with a fixed convergentdivergent nozzle and a movable convergentdivergent nozzle, the latter being operable in response to a pressure drop to a predetermined level in the combustion chamber occurring during burning of the boost grain, to block a portion of the throat areas of the nozzles and increase the combustion chamber pressure during burning of the sustain grain. In one embodiment, Fig. 1, the aft end of the rocket casing 11 houses a boost propellant grain 13, a combustion chamber 16, and an exit nozzle section 17 having the configuration of a convergentdivergent nozzle. The section 17 can be made of asbestos- or silica-reinforced phenolic resin and have a graphite insert 19 forming the nozzle throat. Upstream from the section 17 is a hollow nozzleforming movable body 21 having a convergentdivergent throat section 22 and formed of graphite or a reinforced plastic. The outer wall 23 of the movable body 21 has a surface 27 which will act as a seal against the forward convergent surface 25 of the nozzle section 17. Disposed within the section 17 is at least one, and preferably three or more, housings 28 which serve as cylinders for pistons 29. Each piston 29 is fixed through a rod 30 to a support arm 31 secured to the movable body 21. Hydraulic fluid within each housing 28 prevents normal movement of the piston 29 from its forward position, as shown. Connected to each housing 28 is an outlet line 35 and an explosivelyactuated servovalve 37, the latter being actuated by means responsive to a drop to a predetermined pressure level within the combustion chamber, Fig. 7 (not shown) to release the fluid from the housing 28 through a dump port, the force of the combustion gases then moving the body 21 towards a closed position. Initially the movable body 21 is in an open position, permitting the gas to flow through its nozzle section as well as around the body and between it and the nozzle section 17, as shown by the arrows. The combined area of these two nozzle areas is greater than that of the throat insert 19 of the nozzle section 17, thus allowing the latter to govern the chamber pressure. In an alternative embodiment, Fig. 3, an internal body 53 is shaped about its outer periphery so as to form with a portion 51 disposed in the aft end of the rocket casing 47 a first annular convergentdivergent nozzle 57. The body 53 is permanently supported by struts 55, and has a second convergentdivergent nozzle 59 formed within it. Just upstream of the annular nozzle 57 is disposed a torus-shaped, movable body 61. In the open position shown, the gases from the boost grain 49 flow, as shown by the arrows, around the torus and through the throat portion of the first nozzle 57, as well as through the second nozzle 59. Actuating means 63 are essentially the same as those in the first embodiment.
