Title: Improvements in or relating to electrical synchronising systems
IPC: H04N1/36
Filed: 1939-10-09
Abstract: 535,395. Electric synchronizing system. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 9, 1939, No. 27530. Convention date, Oct. 8, 1938. [Class 40 (iii)] In synchronizing systems especially intended for copying-telegraphy, a dynatron oscillator is used to control a receiver under control of a periodic pulsation from the transmitter. As shown in Fig. 1, an amplifier 13 receiving the signals at 11 and connected to a recorder by leads 31 is also connected to a coil 27 of a magnetic commutator 25 having another coil 29 connected to a dynatron oscillator 15. This oscillator is connected through an amplifier 17 to a phonic-wheel 19 controlling a synchronous motor 21 driving the armature 23 of the magnetic commutator, which armature is also intended to act as recording member. When the motor 21 is in phase and in synchronism with the incoming pulses, little or no transfer takes place between coils 27, 29 ; but if the motor fall out of phase, strong pulses are fed through the coils 27, 29 to the dynatron oscillator to adjust its frequency and thereby restore phase and synchronism to the member 23. In a modification the magnetic commutator is replaced by a bar commutator. In another modification, Fig. 4, the motor 65 is driven directly by the output currents of the dynatron oscillator VT-6 suitably amplified by valves VT-7, VT-8, VT-9, VT-10. The signals are fed by a transformer T-1 with a potentiometer P-1 to an amplifying valve VT-1 and thence by a transformer T-2 to a double-diode-triode valve VT-2, which acts as a rectifier and limiter valve. The output of valve VT-2 is fed to a " spacing " valve VT-3 and thence to the driving valves VT-4, VT-5. acting in push-pull to operate the printing bar 71 co-operating with the recording member 23 driven by the motor 65 with the bar commutator 43. A brush 49 of the commutator is connected to the valve VT-5 by a condenser C-3, and the other brush 47 to a potentiometer P-2 in the grid circuit of the dynatron oscillator VT-6.

Patent GB-483474-A (GB)
Title: Process for the manufacture of cellulose aceto-nitrates
IPC: C08B7/00
Filed: 1936-10-16
Abstract: The manufacture of cellulose acetate-nitrate is carried out in two stages, the first causing nitration and the second acetylation, by causing anhydrous cellulose to react at about normal temperature with a mixture of acetic acid and nitric acid, said mixture containing at least 33 per cent of nitric acid, removing the waste acid, washing the product and bringing it into reaction with a mixture of acetic anhydride and benzene, the temperature being gradually raised to 25-30 DEG  C.  The nitration mixture may contain diluted nitric acid or diluted acetic acid. The nitrated cellulose from the first stage may be washed with acetic acid or benzene, and the cellulose acetate-nitrate from the second stage with benzene or an organic liquid, e.g. acetone or methyl ethyl ketone, which swells the cellulose acetate-nitrate. These liquids are then removed by treatments with cold and hot water.  The product is stabilized by adding to the wash benzene or other liquid alkaline and/or alkaline earth salts of aliphatic acids possessing long carbon chains. Acetone-insoluble products are rendered soluble by dissolving in formic or acetic acid, and saponifying in the presence of sulphuric, phosphoric or perchloric acid.  The saponification may also be carried out in suspension in a liquid having a swelling but not a solvent action on the cellulose derivative.

Abstract: 1,109,130. Sheet delivering apparatus. HAMILTON TOOL CO. 5 July, 1965, No. 28395/65. Heading B6H. Paper web 36 is fed to a rotary cutting machine 30 and the sheets 40 which are severed by a knife blade 32 are guided by superposed guides 326, 328 into the nip of speed-up rollers 80, 82 disposed in front of the sheet feeding path defined by a plate 90 and lower run 46 of conveyer belts 44 moving at a speed equal to the peripheral speed of the rotary cutting machine. The speed-up rollers 80, 82 are driven at higher speed than the rotary cutting machine to effect clean cutting of the sheets and overlapping of the sheets. Overlapping of the sheets is effected by a knock-down roller 84, whose knock-down fingers 86 press the trailing edge A1 of a preceding sheet against the inclined portion 91 of plate 90 to enable the leading edge B1 of a succeeding sheet to overlap the said sheet. The sheet 40 is subsequently lifted by suction into engagement with the conveyer belts 44, the suction being created by compressed air issuing from a nozzle in a duct 58, Fig. 10 (not shown), and leaving a discharge opening 56 disposed on the downstream side of the duct 58. Conveyer belts 44 transfer the sheet 40 to the further conveyer belts 216 moving at a reduced speed and having a similar suction duct 218. To prevent wrinkling of the sheet on account of change of speed a pair of rollers 106, 108 is provided, a lug 104<SP>1</SP> on the roller 106 which rotates at a reduced speed with respect to the conveyers 44, engaging the trailing edge of the sheet 40 at the time when the leading edge is engaged by rollers 100, 101 which guide the sheet into engagement with the conveyer belts 216 and overlapping relationship with a number of preceding sheets, Fig. 4 (not shown).
