Patent GB-817848-A (GB)
Title: Dictation system
IPC: H04M1/65
Filed: 1957-04-04
Abstract: 817,848. Centralized dictation systems. DICTAPHONE CORPORATION. April 4, 1957 [April 10, 1956], No. 11002/57. Class 40(4). When speech currents are applied to a dictating machine they immediately operate a relay to actuate the driving motor. In the recording circuit the speech currents are delayed by 200 msecs. by means of a magnetic drum so as to enable the record to achieve proper speed before the speech currents are impressed thereon. Generalarrangement.-When a subscriber gains access to a dictating machine at a telephone exchange his speech currents are delayed by 200 msecs. in a delay device 28, Fig. 1, before being applied to the recording circuit 48. The speech currents are also applied immediately to a voice-operated clutch relay 90 which operates solenoid 94 to clutch the motor to the recording medium so ensuring that the recording medium achieves proper speed before recording begins. For play back the subscriber dials an appropriate digit which causes selector 22 to energize play-back relay 114 and control relay 148, so reversing switch 58. Relay 148 operates clutch solenoid 94 and the recorded signals are picked up by reproducing head 156, and fed by amplifier 64 over leads 80, 82 to the subscriber. The normal release time of clutch relay 90 is increased during play-back by 20 per cent. If there are no recorded signals a time-out relay 136 ensures that the system goes back to normal condition for recording after a predetermined time of 10-20 seconds, by restoring relay 114 and switch 58. While voice-operated relay 88 is energized the time-out period cannot start. Speech delay unit, Fig. 2.-Speech currents from line are applied to a 3-stage amplifier feeding a voltage-doubling rectifying circuit 316, 320 which supplies negative feedback to the amplifier. The amplifier feeds stabilized speech currents to the writing head 348 of a magnetic drum from which the signals are picked up by a read-head 354. An erase head 356 is associated with an oscillator 360 which supplies the writing head with an additional high-frequency signal. This high-frequency signal is filtered out before the speech signals are amplified at 412 and fed to the recording circuit. Voice-operated relay unit, Fig. 3.-The speech currents are applied to a 3-stage amplifier feeding a voltage-doubling rectifier circuit 502, 504. The anode of rectifier 502 is biased negatively so that it does not respond to noise but causes amplifier 518 to conduct heavily when the threshold amplitude has been exceeded. Tube 518 feeds voice-operated relay 90. When the voice signals cease tube 518 continues to conduct and hold relay 90 operated for about ¢ second while capacitor 520 discharges. During playback a further capacitor 546 is put into circuit to increase the release time. The charging time of capacitor 520 is 5 msecs. so that relay 90 does not pull up due to loud but short background noises. Several features of the dictating machine are as described in Specification 811,562.

Title: Improvements in or relating to Torpedo Diverters.
Inventor: FOUST RODGER OSGOOD
IPC: B63G9/00
Filed: 1917-07-31
Abstract: 114,096. Foust. R. O., and Le Pan, F. July 31, 1917. Torpedo nets and screens.- A torpedo-diverter comprises hollow pivoted booms 3, a net 9 of electrically-insulated wires in circuit with a source of current, a heavy 'bottom bar 24 suspended by telescopic side hangers 14, and pistons 19 slidable within the booms to lift the bottom bar 24 by compressed air so as to strike and divert the torpedo 10, as shown, immediately the net 9 is broken by the impact of the torpedo. Normally the pistons 19 are held stationary by electro-magnets 33 against the action of compressed air supplied through the conduit 38, 39. The breaking of the net, however, opens the electric circuit and releases the pistons which are connected to the bottom bar by cables 20.

Patent GB-776041-A (GB)
Title: Improvements in or relating to mechanism for the feeding of single sheets from a pack or pile
IPC: B65H3/34
Filed: 1950-08-05
Abstract: 776,041. Feeding sheets. HEYWOOD B. C. Aug. 3, 1951 [Aug. 5, 1950], No. 11233/50. Class 100(1) Mechanism for the feeding of single sheets from a pack or pile 9 of the kind in which a suction operated feeder member 7 feeds a succession of single sheets to the nips of feed rolls 14, 15, comprises a pipe 12 for supplying an air blast against the leading edge of the uppermost sheet; resilient stripper fingers 13 and a suction separator 7 which, after taking up a sheet, is first moved upwardly and backwardly, causing the sheet to buckle against an abutment 10 and separate from any other to which it may be attached, and is then moved forwardly towards the feed rolls 14, 15. The level of sheets is maintained by the operation of a switch 40 controlling a motor which raises the sheets. The movments of the rack 7 are controlled by a lever secured to the sucker and having a follower 5 in contact with a stationary U-shaped cam 4. The sucker 7 is pivotally mounted in a spindle 7a secured to a lever 7b which is oscillated by a shaft 28. The relative movement of the feed rolls 14, 15 operates a switch 3 whereby the simultaneous feed by the suction member 7 of two or more adhering sheets causes cessation of feeding by the member 7, and prevents the delivery of the adhering sheets to the machine to which they are normally fed. Operation of the switch 3 by the feed of two or more sheets energizes a solenoid 16 which through an arm 20 rocks a shaft 25 and consequently an arm 23 mounted on the shaft 25 and having a hook 24 at its free end which engages a valve member 21 and retains it against closure. The valve member 21 is thus held in a position to admit air into a suction bleed pipe 22 in communication with a suction pipe 6 leading to the sucker 7 thus making the sucker inoperative. An arm 26 also mounetd on the shaft 25 carries stop fingers at its free end which rise between the split portions of an endless belt 1 by which the sheets are fed. Manual depression of the stop fingers releases the valve member 21. The sucker 7 is normally made operative through valve member 21 by a cam 29 on a member 27 fixed to the oscillating shaft 28. Movement of the feed roll 15 by a sheet also serves to maintain open a further switch, normally maintained open by other mechanism during the remainder of the sheet feeding cycle and which when closed stops the driving motor of the feeding mechinsm. The mechanism is thus stopped both on failure of a sucker 7 to feed a sheet at all and on the feeding of two or more sheets. If it is necessary to synchronize the sheet feeding mechanism with the remainder of the apparatus a clutch mechanism is provided comprising an outer driven part 32 and an inner part 31, 33 a spring urged roller 35 normally providing driving connection between the two parts 32, 33. To disconnect the parts a stop bar 37 is inserted which bears against the roller 35 to move it out of engagement with the part 32.
