Title: Ink ribbon feed and reverse mechanism
IPC: H04L13/18
Filed: 1960-04-21
Abstract: 945,606. Ink-ribbon mechanisms. SMITH-CORONA MARCHANT Inc. April 21, 1960 [July 24, 1959], No. 10994/62. Divided out of 945,603. Heading B6F. In an ink-ribbon feeding and reversing mechanism for type-printing machines comprising a rotatable member driven from a constantly rotated member and connected to the driving member of a positive clutch device having two drive positions, and an intermediate neutral non-driving position, the driven members of the clutch in its two positions being connected respectively to the hubs of two ribbon spools, the positive drive is through inclined teeth on the clutch members, means is provided for moving and retaining the clutch driving member in engagement with the driven members, and the reaction force between the teeth moves the driving member to the neutral position when it is not positively maintained in one of its driving positions, and means is included to shift the position of the clutch driving member to reverse the drive when the ribbon on either spool from which ribbon is being unwound becomes substantially exhausted. The ribbon mechanism is incorporated in the high-speed teleprinter described in Specification 945,603 and which is arranged to operate so that the ribbon-feed is discontinued if signals have ceased for a predetermined period, and in which, on resumption of signal reversion, the ribbon feed proceeds in the same direction as that prior to the interruption. Ink-ribbon feed mechanism.-The ink ribbon is passed from spools 945, 946 over guiding rollers 968 with associated operating rollers 971, 972 and means to guide the tape over a guide plate 924 for the tape and beneath the type-wheel (not shown). The spools are alternately driven from clutch members 931, 932 having inclined driving teeth and a slidable driving sleeve 937 on a shaft 906 driven from a continuously rotated member of the receiver by a chain 342. The selective direction of the ink ribbon feed is controlled by magnets E1 E2 which through an armature 965 and lever 964 rotate a yoke member 962 engaging pins on a clutch operating member 942 connected to sleeve 937. When the ribbon on a spool is nearly exhausted, a tag member raises, for example, the roller 971 which via arm 974 operates a micro-switch S1 to energize the magnet E1 to move the clutch to effect the drive of the empty spool. If incoming signals cease for a predetermined period, e.g. 1 sec., the magnet E1, or E2, is de-energized, and the clutch control member 942 takes up a central non-driving position due to the inclined teeth on the clutch driving and driven members. When signals are resumed, a memory circuit effects re-energization of the appropriate magnet E1 or E2 so that the ribbon movement continues in the same direction as before the interruption. The chain drive 342 between the constantly rotating members 340, 941 is passed over tensioning and direction-changing rollers.

Abstract: 564,788. Party-line systems. NORRIS, W. H. July 8, 1943, No. 11073. Addition to 554,772. [Class 40 (iv)] The system described in the parent Specification is modified by the provision of a separate magnet at each sub-station for restoring the selector, these magnets being connected in parallel between one of the speaking wires and an additional common wire so that they are all controlled by the replacement of the receiver at anv sub-station. The ratchet-wheel 4 of the selector may be provided with a spring-biassed holding pawl 36 which is withdrawn when the restoring magnet 35 is energized, Fig. 1, or when it is released, Fig. 3. Alternatively, the ratchet-wheel as it steps may wind up a cord 39 attached to the core 38 of a solenoid 35a which restores the selector by its energization, Fig. 2. When the arrangement of Fig. 1 or 2 is used, the magnets 35 (or solenoids 35a) are energized over contacts 41 which are closed momentarily when the receiver is replaced by the engagement of a pawl 42, Fig. 8, on the switch-hook with an arm 47, the pawl finally slipping off the end of the arm and allowing the contacts to reopen after a delay imposed by a fly-wheel 50. When the arrangement of Fig. 3 is used, the contacts 41 are closed by the upward movement of the switch-hook. The circuits may be modified to operate with a central battery, and the restoring magnet may be in a local circuit controlled by a relay connected to the common wires.

Title: Improvements in oscillation control apparatus
IPC: H03B17/00
Filed: 1931-04-15
Abstract: 385,314. Converting ; oscillating motors. COMMUNICATION PATENTS, Inc., 60, Broadway, New York, U.S.A. April 15, 1931, No. 11140. Convention date, Aug. 2, 1930. [Classes 35 and 38 (ii).] A standard frequency is produced by a crystal oscillator 30 kept at a constant temperature as described in Specification 372,521, [Group XL], and a related lower frequency is produced by a pendulum 5 having its frequency controlled by the oscillator 30. At the bottom of the pendulum swing, light from a source 18 is reflected by a mirror 11 on the pendulum to produce interference bands on a semi-transparent film 17. A photo-electric cell 25 is focussed on the film and produces from the interference bands a frequency depending on the speed of the pendulum. This frequency is amplified, passed through a phase-shifter 38, and combined in a thermionic valve 37 with oscillations from the standard. The output from the valve varies with the phase relation between the two oscillations and is passed through a heating winding 13 in the pendulum to bring its frequency to exact relationship with the standard frequency. At one end 42 of the travel of the pendulum, light from a source 43 is reflected by the mirror 11 to a photo-electric cell 44 to produce an electric impulse which is amplified and used at 46 to drive a television apparatus, as described in Specification 360,470, [Group XL]. The impulse is also combined in a lead 49 with oscillations from the standard source 30 and excites an electromagnet 50 which imparts a propelling force to a polarized element 15 on the pendulum depending in degree on whether the impulse is in phase with a peak of the standard frequency, Fig. 3 (not shown). At the other end 55 of the pendulum travel, a mirror 10 on the pendulum produces interference bands on a film 57. These bands cross the field of view of a photo-electric cell 60 with a frequency varying down to zero at the extreme limit of the pendulum travel, Fig. 2 (not shown). Frequencies above a certain limit pass through a filter 66 and a rectifier to energize an electromagnet 72, and frequencies below the limit pass through a filter 65 and an oppositely directed rectifier 69 to energize the electromagnet in an opposite direction. Thus, as a polarized projection 14 on the pendulum enters a slot in the core of the electromagnet, it is first attracted, then repelled, and finally retarded in its movement.
