Title: Improvements in or relating to a method of and vacuumizing apparatus for sealing cans or like containers in a vacuum
IPC: B67B3/24
Filed: 1932-06-09
Abstract: 398,968. Seaming. GENERAL FOODS CORPORATION, 250, Park Avenue, New York, U.S.A.-(Assignees of Rector, T. M. ; 175, Wood Street, Rutherford, New Jersey, U.S.A.) June 9, 1932, No. 16300. Convention date, June 16, 1931. [Class 83 (iv).] A method of sealing a can &c. in vacuo comprises applying successively higher values of vacuum in stages to the container, to remove substantially all of its contained atmosphere without disturbing its contents and then sealing the container while applying to it a vacuum of equal or higher value than that applied in the last of said stages. Cans from a conveyor 7 are fed by a rocking arm 9 into pockets of a rotating valve 4. At 25, 21 air contained in the container and its pocket is shared, through a pipe 22, with a highly evacuated pocket just leaving the seaming chamber 2. On further rotation of the valve 4, to port 23, the pocket and container are subjected, through pipe 24, to the first stage of a vacuumizing pump 15, 17 which extracts more of the contained air, and then at port 26 the remaining air is removed, through pipe 27, by the second stage of the pump, an expansion chamber 28 being preferably provided to assure quick removal. The seaming chamber is exhausted also by a pump 29. The seamed cans are removed from the seaming chamber by another rotary valve 41, the pockets of which are connected up to the inlet valve casing to subject delivered containers to successively decreasing values of vacuum and then removed by a conveyor 13. The valve casings are provided with circumferential grooves top and bottom, exhausted by a pump 35, to prevent leakage of air into the pockets and the containers therein. The valves may be cylindrical or conical, and in the latter case they may be spring urged upwardly. The valve casings may be formed with grid-like surfaces, for containing lubricant, and with helically arranged ribs to bias the rotating valves upwardly to avoid undue wear &c. The various grooves &c. in the valve casings may be dimensioned so that the sidewise effect of suction is balanced.

Title: Improvements in or relating to wireless transmitting apparatus
IPC: H04B1/04
Filed: 1944-09-04
Abstract: 581,314. Wireless transmitting apparatus. ANDERSON, W. P., and WRIGHT, C. S. Sept. 4, 1944, No. 16886. [Class 40 (v)] The audio-frequency amplifier of a radio transmitter is provided with delayed automatic gain control, and the delay voltage is derived from the same variable voltage source as is used to vary the power output of the transmitter. The microphone is coupled by a transformer 1 and a chain of amplifiers 2 ... 6 to a terminal 62 of a modulating carrierwave amplifier, not shown. The output of the valve 6 is also applied to the grid of a rectifier valve 23, the anode current of which traverses resistances 26, 27 from which A.G.C. voltage is taken through a smoothing circuit 32 to the grid of the valve 2. The grid-cathode voltage of the valve 23, which determines the delay voltage of the A.G.C., is derived from a potentiometr 54 connected as load to a rectifier 57 supplied from an A.C. source which is the same as that supplying power to the carrier output amplifier. Thus when the output power is reduced, the delay voltage is also reduced and the audio input to the modulator correspondingly limited. The voltage at the terminal 68 may be applied to the suppressor grid of a carrier amplifier. The transformer 35 supplies anode current for the valves 2 ... 6 via rectifier 34, filament current for the valves 2 ... 5 and 23 via rectifiers 39, 40 and grid bias for valves 3 ... 5 via rectifiers 44. Anode current for the valve 23 is derived from a rectifier 49, filament current for the valve 6 from a secondary coil 63 without rectification, and grid bias for the valve 6 by a cathode resistance 48.
