Title: Improvements in carrier-wave signalling systems
IPC: H04B3/32
Filed: 1929-06-19
Abstract: 314,382. Standard Telephones & Cables, Ltd., (Assignees of Black, H. S.). June 26, 1928, [Convention date]. Wired - wireless systems ; relaying or repeating systems.-In order to reduce wave reflections and cross-talk in a two-way carrier-wave repeating system in which different frequencies are used for the two signalling directions, the attenuation-equalizers in both line sections are arranged between the terminals of the corresponding bandfilter networks, the major portion of the network lying ahead (in the direction of the amplifier) and the remainder to the rear. This disposition reduces the standard of filtering required, and so effects an economy in filter design. The attenuation-equalizers may be adjusted automatically by means of motors responsive to special pilot signals. Incoming signals of one carrier frequency from the line 2 pass first over a small portion 10 of a high-pass filter, then through a resistance network 11 and an attenuation-equalizer 12, and thereafter through the major portion 13 of the high-pass filter to the amplifier 1, and so to the output high-pass filter 14 and the outgoing line 3. Incoming signals from the line 3 on a lower carrier frequency take the corresponding path through low-pass filter 20, resistance network 21, attenuation-equalizer 22, the major part 23 of the filter to the amplifier 1, and so to the low-pass output filter 24 and line 2. The attenuation-equalizer for the line 2 consists of a fixed unit 40 of known type together with a variable unit 41. That for the line 3 is of similar design, both being independently adjustable for different frequencies and line conditions. Gain regulation through the equalizers 41, 51 may be controlled automatically by means of pilot waves, of different frequencies, sent over the two lines. Each control signal wave is selected by a tuned circuit 28 coupled to the output of the amplifier, and energizes a motor 35 in known manner through a milliameter relay 32 and reversing-switches 31<1>. The type of equalizers used are described in Specification 202,284, [Class 40 (iv), Telephones &c.], and in U.S.A. Specification 1,591,073.

Title: Improvements in or relating to parametric amplifiers
IPC: H01J25/49
Filed: 1958-06-17
Abstract: 857,652. Velocity-modulated tubes. WESTERN ELECTRIC CO. Inc. June 17, 1958 [June 20, 1957], No. 19390/58. Class 39(1). In an electron-beam parametric amplifier the beam passes first through resonator 16, Fig. 2, which velocity-modulates it at the pump frequency and then, after a drift space 24 preferably of a quarter plasma wavelength, into double gap resonator 23 to which is applied the signal frequency from source 36. By choosing the length between the gaps 30, 35 to be n + ¢  cycles of the signal frequency the beam can be made to present to gap 35 an inductive susceptance which varies at the pump frequency and produces a parametrically-amplified signal at output 37 ; at the same time noise signals on the beam are cancelled at the two gaps. A choice of gap separation of n + 1 cycles would give a capacitative susceptance but this does not have the noise cancellation property. The pump frequency need not be exactly twice the signal frequency provided the resonator 23 will support the idler frequency also. In other forms the resonator 16 is replaced by a travelling-wave arrangement which, to economise in pump frequency energy, may be of backward-wave type, the line 62, Fig. 5, having non-reflective termination 64 near the gun and the pump signal being put on by helix 63. The forward-wave arrangement would work in the " Kompfner Dip Condition." Magnetic focusing is employed. Specification 839,595 is referred to.

July 10, 1933, No. 19465. Convention date, April 28. Addition to 395,602. [Class 82 (i).] A modification of the method described in the parent Specification for removing impurities such as cadmium and lead that have a lower and a higher boiling point than zinc comprises withdrawing lead-free zinc from the top of the lead eliminating column, introducing the lead-free zinc into the cadmium eliminating column at a point intermediate its top and bottom, heating the lower part of the cadmium eliminating column, and withdrawing zinc freed from cadmium from the base of that column. An apparatus for carrying out the improved method comprises a retort 10 for volatilizing the impure zinc, a lead eliminating column 16 comprising trays 19 which retain pools of the molten zinc that descends in countercurrent with the ascending vapour, a cadmium eliminating column 23 which also comprises trays, and a heating chamber 24. Pure zinc passes into a heated sump 28 and cadmium-rich vapour is condensed in a condenser 34 provided with a well 36 from which molten metal overflows into the top tray of the purifying column. A cadmium-rich fraction of the vapour is condensed to dust in a canister 40. A reservoir 43 containing inert gas compensates for gas pressure changes in the system and prevents the entry of air.
