Abstract: 1,078,947. Pilot operated automatic gain control. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 13, 1965 [Sept. 16, 1964], No. 38977/65. Heading H4R. A transmitting system, Fig. 1, utilizes separate lines 1 and 1<SP>1</SP> for each direction of transmission and a pilot signal is extracted from the incoming line at each terminal station by a pilot receiver, e.g. 13, 14, 15, and used to control the gain of the final repeater amplifier 10 and the gain of an intermediate repeater, e.g. 6, by a frequency modulated signal transmitted over the outgoing line from the repeater. The frequency modulated signal is derived from an oscillator 21 whose frequency is controlled by an element, e.g. a capacitor, adjusted by a motor 22 which is driven in one direction or the other whenever the pilot level deviates by more than a predetermined amount. The frequency modulated signal is extracted from the line at the intermediate repeater station by a filter 18 and applied via limiters 27 and 20 to a frequency detector 19 the output of which controls a feedback impedance 11 of. the repeater amplifier 6. In order to prevent misadjustment if the pilot signal fails at the terminal station a limit device 24 is provided which detects abnormal changes in pilot level and removes the supply to motor 22 so that it remains in the last adopted position. In addition a proportion of the f.m. control signal from the channel being controlled is mixed via an attenuator, e.g. 26<SP>1</SP>, with the control signal appropriate to that channel transmitted on the other channel so that if, for example, channel 1<SP>1</SP> is interrupted at 5<SP>1</SP> the absence of pilot signal at the terminal station 91 will operate limit detector 24<SP>1</SP> so that the last adopted position of motor 22<SP>1</SP> is held, fixing the frequency of the control signal fed to channel 1. The fault at repeater 5<SP>1</SP> will also interrupt the control signal fed, via filter 18 &c., to control the gain of amplifier 6. Due to the signal fed via attenuator 26<SP>1</SP> from the control signal in channel 1, primarily intended for the control of repeaters in channel 1<SP>1</SP>, the gain will still be controlled in an approximate fashion to maintain operation of channel 1. Under normal conditions the signal fed via limiter 27 swamps the signal from attenuator 26<SP>1</SP> so that the signal from 26<SP>1</SP> has little or no effect on the control. A threshold device is provided either integrally with the limiter 27, 27<SP>1</SP> or separately at 29, 29<SP>1</SP>, Fig. 2 (not shown) to inhibit the control signal passing therethrough if the level deviates abnormally.

Abstract: 1,090,520. Logic circuits; checking. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 1, 1966 [Oct. 18, 1965], No. 38991/66. Heading G4H. A logic circuit performs both AND and OR operations on two operands, a checking means responsive to the parity of the operands and of the results indicating error when in receipt of odd inputs. In Fig. 2, corresponding bits of two 8-bit operands X, Y are ANDed at 10, ORed at 12 and EXCL-ORed at 13. Parity bits are calculated for the three results at 16, 18, 19 and one of the results and its parity bit are gated to a register 24. The calculated parity bits are fed to a parity check circuit 14a which thus effectively checks the operation of the logic circuits 10, 12 13. The parity bit from 19 and (odd) parity bits accompanying the operands X, Y are fed to a second parity check circuit 15 which thus effectively checks the input's parity. Fig. 1 (not shown) shows a modification in which the circuits 13, 19, 27, 15 are omitted and the parity bits accompanying operands X, Y are fed to a circuit corresponding to 14a in place of the output of circuit 19.

Title: Improvements in or relating to nuclear fuel
IPC: G21C3/64
Filed: 1963-10-08
Abstract: Individual nuclear fuel particles, e.g. of UC2 and/or ThC2, are coated with pyrolytic carbon, and the particles are dispersed within a graphite matrix; the resultant mixture is compacted, impregnated with a polymerizable substance, cured and carbonized; the impregnating, curing and carbonizing are repeated to reduce the gas permeability of the body; and the carbonized body is partially graphitized. In an example, nuclear fuel particles containing equal parts of UC2 (enriched or unenriched) and ThC2 of an average particle size of about 150 microns were each coated with a layer 50 microns thick of pyrolytic carbon by heating the particles to about 1500 DEG C. in a methane atmosphere.  These particles, 1 part by weight, were then mixed with 3 parts by weight of 200 mesh graphite powder and 0.3 part by weight of pitch, the resulting mass being shaped in a die at 700 DEG  C. and 4000 p.s.i. for 30 minutes to form a fuel body having a maximum pore diameter of less than 2 microns. The fuel body was then degassed and immersed in a mixture of furfuryl alcohol and maleic anhydride, 10 mols to 1 mol respectively, for 16 hours after which 5% of the filled pores were cleared of impregnant and the resin cured at 60 DEG  C. for 16 hours, then at 100 DEG  C. for 5 hours. The body was subsequently moved to a carbonization furnace where it was heated to 500 DEG  C. at a rate of 13 DEG  C./hour and to 900 DEG C. at a rate of 50 DEG  C./hour.  The body was again impregnated and then subjected to curing and carbonizing steps but this time the porecleaning step was eliminated.  The carbonized substance was finally partially graphitized by slowly heating the body to 1900 DEG C. and maintaining this temperature for 30 mins. The resulting product was found to be crack-free and to have a gas permeability of less than 10-6 cm.2/sec. (to helium at room temperature).
