Title: Cable drum apparatus

Filed: 1972-12-06
Abstract: 1417010 Winches GARRETT CORP 6 Dec 1972 [8 Dec 1971] 56244/72 Heading B8B A winding apparatus for a hi-line system between vessels subject to random wave motion comprises drums 56, 58 for the cables 26, 28 of the system, interconnected by a differential gear 68, and a drum 54 for a tension compensating cable 38 and coupled to the planet carrier 70 of the differential gear 68, the latter permitting random movement between the vessels to be superimposed on the motion of the drums 56, 56 causing traversing of the hi-line trolley. With the load trolley of the system staioned at the supply ship, cable 26 and drum 56 are held stationary by pinions of stationary drive motors 90, 92, which are mounted on a plate 82 braked by an electric brake 112, the random movement causing the line 28 with drum 58 to pay out and wind in and causing the drum 54 to similarly move via the differential planet 70 carried on a shaft 78 coupled to the drum 54. The cable 36 wound on the drum 54 extends to a tensioning device, to maintain a constant tension on the winding apparatus to maintain the cable 28 tensioned during the random movements. To traverse the trolley between the vessels, the motors 90, 92 are started and drive the drum 50 since the motor mounting plate 82 is still braked, the drum 58 being simultaneously counter rotated through the gear 68, and any variation in tension in the system being absorbed by superimposed rotation of the drum 58. As the trolley approaches the receiving vessel, the brake 112 and motors are de-energized to free the motor plate 82 and a clutch 98 is energized to lock the drum 54 to the plate 82 whereby random movements of the vessels payout and wind in both drums 56 and 58, the tension still being applied by the drum 54.

Title: Adjustment device for the flow of a liquid propellant into t hypergolic reaction system
IPC: F02K9/72
Filed: 1968-12-19
Abstract: 1,217,280. 280. Rocket propulsion plant. NORD AVIATION SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. Dec. 19, 1968 [Dec. 22, 1967], No.60521/68. Heading F1J. [Also in Division F4] In a hypergolic reaction system, a device 1, Fig. 1, for regulating the flow of a liquid propellant into a rocket combustion chamber 5 containing the other propellant for the reaction comprises an axially slidable piston 8 controlling the flow of propellant through an orifice 7 from an inlet 6 to a distribution duct 2 having injectors 3. The piston 8 slides in a chamber 1a and has acting on its upper surface the pressure of the propellant immediately upstream of orifice 7 and on its lower surface the pressure of propellant tapped off from inlet 6 through passage 11 and restriction 12. The latter pressure is assisted by a spring 13 which holds a ball 16 against the push rod 18 of a bellows 19. The position of the ball 16 and hence the leakoff therepast to a discharge passage 17 is controlled by the pressure of an inert gas within the bellows 19. The gas is supplied to the bellows 19 through a passage 20 having a setting needle 21 and an electrically controlled leak-off 22, 22a. Thus adjustment of the leak-off 22, 22a controls the position of piston 8 and its tapered extension 8a and hence the flow of propellant through orifice 7 to distribution duct 2. A by-pass passage 9 around orifice 7 maintains a pilot flow of propellant to duct 2 when orifice 7 is fully closed. Each injector 3 comprises, Fig. 3, a frusto-conical cup 37 sliding on a central body 38 and held against a seat 40 by a spring 30. The seat 40 is open to the distribution duct 2 at 41 and is fixed thereto by a threaded sleeve 42. The cup 37 is urged off its seat when the propellant overcomes the force of spring 39. To provide a pilot flow of propellant into the combustion chamber 5, the injector 3 includes a central bore 44 in the body 38 to which propellant flows through drillings 47. A rod 43 with a frustoconical head 46 fits into the bore 44 to provide a pilot injection orifice 45 between the head 46 and the body 38. The size of the orifice 45 can be pre-set by nut 49 on the threaded end 48 of rod 43. The other propellant for the hypergolic reaction may be block surrounding the duct 2 and separated therefrom by a space 35, or a further liquid. Several rocket units (F1 to F8), Fig. 2 (not shown), each having the hypergolic reaction system described may be used to control the attitude of a space vehicle, the liquid propellant being a mixture of NO 3 H and N 2 O 4 .

The float has a portion 11a in which lead wires 15, 16 feed to a lead switch 14 and on which a permanent magnet 13 is pressed so that on excess downward movement of the float by deformation of member 7 indicating leakage of fluid, switch 14 opens due to the weakened effect of magnet 13 causing an alarm 19 to be operated. The reservoir is provided with a cap 5 having threads trapezoidal in cross-section which mate with corresponding threads 41 on the reservoir casing 4 to provide a spiral air passage communicating through a slit formed between a gasket 9 and the cap with an air chamber in the float member 11.
