Patent GB-1136555-A (GB)
Title: Improvements in or relating to the printing devices
IPC: G06K15/06
Filed: 1966-03-28
Abstract: 1,136,555. Printing machine control circuits. ING. C. OLIVETTI & C. S.p.A. 28 March, 1966 [29 March, 1965], No. 13520/66. Heading G4H. In a printing machine of the kind having a hammer Ml &c. for each character position adapted to be operated at the correct instant to print from type members on a moving drum 1, the input being from a cyclic memory 14 having a cycle shorter than the interval between the instants when successive characters come under the hammers, the hammers are operated by windings EM1 &c. connected to thyristors TH1 &c. selectively conditioned by the store to be operated at the correct instants by a power pulse source. The cyclic memory 14 consists of a magneto strictive delay line with a recirculating gate 13. The complete line of characters recirculates in delay line 14 during the time taken for the drum 1 to move from one printing position to the next. Oscillator 11 controls the recirculation and also applies character pulses to a counter 12 which energizes lines U1 &c. in turn to open successive character gates G1 &c. The bits relating to each character are staticized at 10 and compared at 9 with bit groups read off a coded disc 3 on the end of the character drum. When a match occurs a signal appears on lead 22 to enable the gates G1 &c. The corresponding thyristor is thereby made conductive and is held in this state by a low voltage from a source 7. When all the characters have passed through the delay line 14 a high voltage pulse from source 7 draws sufficient current through those thyristors that are conducting to operate the corresponding print magnets. The line of print is thereby built up by printing all the A's, then all the B's and so on. When all the characters have been printed, the voltage from source 7 briefly becomes negative to reset the thyristors. The source 7 consists of a transformer having secondary windings connected to rectifying networks giving the desired voltage levels. These are switched in turn to an output lead by transistors connected to tappings on a delay line. A pulse applied to the delay line operates transistors in sequence to provide the desired succession of voltage levels. A Zener diode is used to stabilize the output voltage levels.

IPC: A01K89/015
Abstract: 135,251. Young, J. W. Nov. 8, 1918. Reels, rod.-Relates to reel-braking mechanism adapted to engage with the inner surface of an annular flange formed on the rear face of thespool. Two brake blocks 12, 15 are mounted on the respective arms 4, 5 of a bell-crank lever, which has a handle 8 projecting through a slot 9 in the flange of the back-plate or frame B. The bell-crank-lever is pivoted to the back-plate at G and is formed with a circular piece 11, which fills the slot 9 so as to exclude dirt &c. The brake 12 is normally applied, and the brake 15 disengaged, by the spring 13. By moving the handle 8, the. brake 12 is first disengaged, and, by a further movement, the brake 15 is applied. The braking-pressure of the brake 15 can be adjusted, or entirely prevented, by means of the adjustable stop 16, which consists of a milled nut adapted to travel along a screwed rod mounted in a hole in the back-plate, through which the side of the nut projects somewhat, so as to be operable by the finger. A sliding plate mounted on the exterior of the back-plate embraces the nut, and suitable indicating-marks may be employed on the sliding plate and backplate, to show whether the brake is " on " or " off. " The brakes preferably consist of a block 15. Fig. 5, of leather &c. mounted in the end of a tubular socket 17, which works in a hole 18 in the end of the bell-crank lever, under control of a spring 19 and a screwed stop-rod 20. For use as an emergency brake &c., a second finger-operated brake 28 may be provided which is normally held inoperative by a spring, for example, by an extension 37 of the spring 13.

Title: Swaging tool
IPC: B21J15/02
Filed: 1965-03-30
Abstract: 1,091,962. Riveting. HUCK MANUFACTURING CO. March 30, 1965 [July 22, 1964], No. 13528/65. Heading B3U. A tool 20 for swaging a tubular collar 18, Fig. 1, on to a fastener 10 comprises a body 23 having a cylindrical bore 25, a fluid-actuated piston 40 movable in the bore, a holder 52 carrying anvil means 58 for swaging the collar, and a spring 47 for moving the piston in the opposite direction to the fluid actuated means. the anvil means being responsive to the movement of the piston in one direction to move into swaging contact with the collar and being released from the collar when the piston moves in the other direction. The anvil 58 is formed of two or more parts forming a cylinder and having an inner conical surface 58a and an outer conical surface 63 which engages a frustoconical bore 57 in the holder 52. A circlip 60 is received in a groove 61 in the anvil parts and limits the forward movement of the anvil. The groove is wider than the thickness of the circlip. A sleeve 81 abuts the end face of the anvil and carries a circlip 83 which is engaged by the forward end of the piston 40 when it moves to the left. Behind the sleeve 81 are tapered chuck jaws 72 which are internally grooved to engage a grooved portion 17 of the fastener, when the jaws move radially inwards as the piston 40 moves to the right. The tool has a handle (21), Fig. 3 (part not shown) provided with a trigger (90) operating an electrical switch in the circuit of a motor driving an hydraulic pump. Pressure fluid passes through passages 97 and 99 to move the piston to the right. Operation.-The tool is placed on the assembly of workpieces and fastener shown in Fig. 1 and actuated by the trigger (90). As the piston 40 moves to the right the jaws 72 grip the portion 17 and the reaction on the body 23 causes the anvil 58 to be forced into swaging engagement with the collar 18. After the collar has been swaged the fastener fractures at a break-neck 16 and the pintail passes through the tool and is ejected through a slot 37 in a rubber guard 33. When the trigger 90 is released the spring 47 moves the piston 40 to the left, it engages the circlip 83 on the sleeve 81 and through the sleeve moves the anvil 58 forward in the holder 52. This forward movement permits the anvil 58 to expand radially and to be released from the collar 18. In a modification, Figs. 8 and 9 (not shown) the sleeve 81 is omitted or made integral with the anvil (158) the axial movement of which is limited by a circlip (160). The groove (161) in which the circlip is received is wider than the thickness of the circlip. The anvil has two longitudinally extending slots (164) and a cut (165) is made through one of the slots to define a split anvil construction. The chuck jaws (172) directly engage the rear end of the anvil. The setting action occurs as in the previous embodiment, but in this modification as the piston (140) moves to the left the anvil (158) is released from the collar 18 by the action of a spring (176) upon a sleeve (177) and the chuck jaws (172).
