Title: Apparatus for advancing material through a machine
IPC: B41J11/44
Filed: 1969-07-31
Abstract: 1,269,419. Programmed control of machines. BURROUGHS CORP. July 31, 1969 [Dec. 18, 1968], No.38487/69. Heading G3N. [Also in Division B6] Material, such as paper 51 is fed under control of a program tape 23 advanced in synchronism with the paper 51, the paper feed being at alternative rates, and provision is made for advance of the program tape 23 independently of the paper 51. The tape 23 is fed by a roller 25 driven either independently by a motor 35 through engagement of a clutch 33, or in synchronism by a motor 17 through a shaft 11 which also drives pin tractors 55 engaging the paper 51. The motor 17 is coupled to the shaft 11 through either a low speed clutch 13 or a high speed clutch 15. In the rest condition of the apparatus, a brake 19 prevents feed of the paper 51. When feed is initiated by a pulse at 83, the brake is released and low speed clutch 13 is engaged through a flip-flop FF3. The low speed feed continues until a signal occurs on line 95 from a tape reader 27 whereupon a flip-flop FF4 is set to engage the high speed clutch 15, the low speed clutch 13 being disengaged. When it is required to stop the paper 51, the low speed clutch first takes over, and then the brake 19 is applied. Independent advance of the tape 23 is permitted by closing a switch 85 whereby a clutch 31 disengages the roller 25 from the shaft 11, and the motor 35 and clutch 33 are actuated. Independent feed is only possible when the brake is applied owing to an AND gate 77. In alternative circuitry, Fig. 3 (not shown), application of the brake 19 and engagement of the clutches 13, 15 is in each case effected by a high level driver exceeding the rating of the brake or clutch, the brake or clutch being held energized by a low level driver. In further alternative circuitry, Fig.4 (not shown), the low speed and high speed clutches may initially be engaged together, the low speed clutch being disengaged subsequently to leave the high speed clutch operative.

Filed: 1966-09-06
Abstract: 1,189,293. Builder and traverse motions. COURTAULDS Ltd. 6 Sept., 1967 [6 Sept., 1966], No. 39725/66. Heading D1D. In a yarn winding machine in which the yarn guide reciprocates along the spindle or vice versa, the reversal positions of the reciprocation are controlled by subjecting one reversal position to two superimposed motions, one reciprocatory axially with respect to the spindle and the other a gradual unidirectional axial movement, while the other reversal position is subjected to a gradual unidirectional movement axially with' respect to the spindle and towards the reciprocating reversal position. Preferably the unidirectional movements applied to the two reversal positions are in the same direction and at the same constant speed. The gradual unidirectional movements of both reversal positions may each be effected using a snail cam and cam follower. A heart shaped cam, mounted on the cam follower controlling the unidirectional movement of the upper reversal position, together with a cam follower effects the reciprocatory movement of the upper reversal position. Alternatively knock over cams can be used to define the reversal points.

Title: Mechanism for effecting the positional adjustment of nuclear reactor control rods
Inventor: VAUTREY LOUIS
IPC: G21C7/14
Filed: 1966-09-12
Abstract: 1,086,099. Controlling reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. Sept. 12, 1966 [Oct. 22, 1965], No. 40722/66. Heading G6C. A mechanism for effecting the positional adjustment of nuclear reactor control rods comprises first and second vertical operating members 10, 14 pivotally coupled to an intermediate member 12 which forms a lever arm, the first member 10 terminating in a grab 9 for the control rod 8 and the second member 14 extending outside the biological shield wall 2 of the reactor, the intermediate member 12 being provided with a transverse fulcrum pin 15 which is pivotally mounted in a bearing secured to a vertical support rod 16 which also extends outside the shield wall 2. The leak-tightness of the shield wall 2 where it is traversed by the second member 14 is ensured by means of a bellows seal (not shown). The intermediate member 12 terminates at one end in a fork 19 in which is engaged a pivot pin 13 for the second member 14, the fork being intended to permit any lateral movements of these members when they perform either simultaneous or separate movements. The shield wall 2 consists of a shield slab 3 through which are formed openings which provide access to the reactor tank 1 and which are normally closed by means of plugs 4, 5. The drive mechanism also comprises a graboperating device (not shown) consisting of a first vertical rod which causes the grab to open as a result of the displacement of the rod, which rod is pivotally connected to one end of a relay rod pivoted about a pin carried by the intermediate member 12, the other end of the relay rod being pivotally connected to a second vertical or drive rod. The position of the control rod 8 is controlled externally of the reactor, from a control station located above the shield slab 3, by vertical displacement of the member 14. This displacement is considerably less than that of the member 10, thus facilitating the sealing of the member 14 in its passage through the shield wall 2. When the control rod 8 is to function as a safety rod for controlled shutdown of the reactor, the rod is propelled towards the reactor core 7 by rapid movement of the member 14 which is produced for example by the expansion of a spring. The removal of the drive mechanism, after shut down of the reactor, so as to completely clear the space above the core 7 in order that various fuel element handling operations may be effected is described.
