Title: Improvements in and relating to the protection of electric systems against excess voltages
IPC: H02H9/06
Filed: 1926-04-23
Abstract: 251,292. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts Ges.). April 23, 1925, [Convention date]. Protective. arrangements against excess voltages, particularly applicable to telephone lines but applicable also to power transmission lines. An impedance 12, Fig. 1, is inserted in the vicinity of the working apparatus, between the conductor branches 11, which in the case illustrated are telephone wires, and an earthed protection device 14 of the spark gap type is connected to a selected point on the impedance so that the balancing current through the apparatus T is very low. The lines may be connected to the instruments T through transformers 15 as shown in Fig. 2. Where the outgoing and return conductors have unequal electrical constants, the point of connection to the impedance is displaced from the central point to balance this inequality. Fig. 4 shows four conductors with a common return 16 protected by a single protective device 14 at each end. The inductive resistances 12 are tapped in the ratio 1 to 4 and led through a zig-zag choke coil 19 with four limbs to an artificial neutral point to which the protection device is connected. The multiple zig-zag choke may be replaced by several singlelimb choke coils. In addition to the protection described, the lines may be further protected by protective devices Sa, Sb, Fig. 10. directly connected to the lines and having a higher setting than the protective devices connected to the inductances.

Title: Improvements in or relating to photocell hum demodulators
IPC: G11B7/12
Filed: 1942-07-31
Abstract: 556,568. Photo-cell hum demodulators; valve amplifying circuits. RADIO CORPORATION OF AMERICA. July 31, 1942, Nos. 10753 and 10754. Convention date, July 31, 1941. [Classes 40 (iii) and 40 (v)] Relates to photo-electric devices comprising a photo-electric cell 13 having a D.C. supply circuit and an A.C. output cicuit and illuminated by exciter lamp 10, for example through a sound film F. If, as is convenient, the exciter lamp is fed with A.C. this A.C. frequency appears in the output of the cell. In order to avoid this drawback, a second photo-cell 17 is provided and subjected to light from the exciter lamp and arranged to divert a portion of the current supplied to the main cell 13 in proportion to the brightness of the exciter lamp. As shown in Fig. 1, the two cells 13, 17 are D.C. fed through a common resistance 9, so that any fluctuation of the intensity of the exciter lamp 10 causes the cell 17 to produce a fluctuation in the supply to the cell 13 which is opposed in phase to the fluctuations produced in the cell 13 by the same fluctuations of the exciter lamp. Thus these fluctuations are substantially cancelled out of the output of the cell 13, leaving the desired fluctuations produced by the film F free from undesired fluctuations. The capacities across the terminals of the cell 13 allow some undesired fluctuations to get through when the light passed by the film is of low intensity. In a modification avoiding this defect, Fig. 3, the two cells 13, 17 are arranged in a bridge circuit with resistances 19, 20 and a condenser 18 which is adjusted to balance the capacity across the terminals of cell 13. In that Figure, two pairs of cells 13, 17 and 13<SP>1</SP>, 171 are provided and are fed through the potential divider system 26, 27, 30, 31, 32, 33, 34, 35 with condensers 36, 37 from a supply slightly over 150 volts which is limited to and stabilized at 150 volts by a resistance 28 and a regulating tube 29. The outputs from the cells 13, 131 are fed to the grid of the amplifier 38 through condensers 42, 43. The grid has a leak 41 ; and a biasing resistance 39 with condenser 40 is provided in the cathode circuit. The two cells 13, 13<SP>1</SP> may be used for combining sounds from two records for a recording on a single record.

Title: Improvements in or relating to control rods for nuclear reactors
IPC: G21C7/10
Filed: 1962-03-23
Abstract: 931,974. Reactor-control rods. SCHLOEMANN A.G. March 23, 1962 [May 4, 1961], No. 11315/62. Class 39 (4). A control rod comprises a number of neutron-absorbing sections, each having a predetermined concentration of burnable neutron absorbing poison disposed within it, the sections being arranged so that the concentrations of poison therein are sufficient to compensate for the loss in excess reactivity in the core of a nuclear reactor in which one or more of the rods are disposed during the period of time the sections absorb neutrons in the core. In the embodiment illustrated, the sections 15 are in the form of nested shells 9 and stacked within an outer can 11, being spaced from one another by interposed ceramic or metal spacers 19. Each shell 9 is fabricated from a filler material having structural stability at the operating temperature of the reactor and may be aluminium, zirconium or other metal but is preferably a high temperature ceramic such as alumina, beryllia, zirconia, or other suitable refractory metal oxide. The burnable poison is uniformly dispersed throughout the filler material in each shell and, in the case of a thermal reactor, is preferably selected from gadolinium, cadmium or samarium, compounds of these metals or mixtures of these metals and/or compounds. The can 11 may be formed of aluminium, zirconium alloy or stainless steel. The poison concentration is adjusted along the length of the control rod from one section of the next to compensate for variations in neutron flux within the active portion of the reactor core and radially from one shell to the next so as to be sufficient to maintain the neutron flux and power output at relatively constant levels without repositioning the control rods in the core despite the continuing reactivity loss with time in the reactor. In one particular example, each shell is fabricated by hot-pressing in a die a particulate mixture of alumina, Al 2 O 3 , and gadolinium oxide, Gd 2 O 3 , in accordance with a conventional hot-pressing ceramic - forming technique. Specification 852,877 is referred to.
