Title: Improvements in and relating to nuclear reactors
Inventor: DAVID VERNON WARNER
IPC: G21C5/12
Filed: 1958-03-05
Abstract: The primary or secondary coolant of a nuclear reactor comprises an aromatic concentrate or a fraction thereof obtained from a cycle oil having an initial boiling-point of at least 250 DEG  C. and which is obtained from the cracking of hydrocarbon oils.  The cycle oil may be obtained by a thermal cracking process but is preferably obtained from a catalytic process.  The aromatic concentrate may be obtained by extraction, extractive distillation, selective adsorption or selective absorption, but is preferably obtained by treating the cracked cycle oil with one or more selective solvents such as liquid sulphur dioxide, furfural, benzene, nitrobenzene or phenol, and the solvent may be removed by distillation.  The whole of the aromatic concentrate may be used, or the concentrate may be distilled and the fraction boiling between 290 DEG  and 330 DEG  C. used.  The concentrate may be treated to reduce the sulphur content; a treatment with sodium reduces the sulphur content from 3 to 0.3%.

Filed: 1975-02-19
Abstract: 1487439 Radar HOLLANDSE SIGNAALAPPARATEN BV 19 Feb 1975 [28 Feb 1974] 7075/75 Heading H4D Chirp pulse radar apparatus, of the kind comprising a voltage controlled oscillator (V.C.O.) 15 for transmitting a series of linearly modulated pulses of relatively long duration, the start of each pulse being synchronized with the output of a coherent oscillator (COHO) 8 and the received echo-pulses being compressed in a pulse compression filter 6 and then detected in a coherent detector 7 using the output of the coherent oscillator 8, thereby producing video signals, the moving target components of which are extracted by clutter suppression circuitry 14, wherein, during the periods that a chirp pulse is not being transmitted the V.C.O. 15 has its control signal provided by a phase detector 17 operating between the outputs of the V.C.O. 15 and a fixed frequency local oscillator (L.O.) 16 such that the V.C.O. is phase locked to the L.O., whilst during the transmission of the chirp pulse the control signal for the next transmitted chirp pulse is provided by a slope control circuit 27 which determines the rate of frequency modulation of the chirp pulse by measuring at the (now sinusoidal due to the f.m. of the chirp pulse) output of the phase detector 17, the time required for the occurence of k cycles, the synchronization of the start of each pulse at gate 25 and the change over in switch 19 of the control signal for the V.C.O. being produced by a second phase detector 20 between the outputs of the V.C.O. 15 and the COHO 8 and the generation of a timing and switching signal #T by said phase detector 20 indicating a desired phase relationship between said outputs. During the interpulse period, the output of phase detector 17 is directed via integrator 18 and gate 26 to the V.C.O. 15. During a pulse transmission, switching signal #T blocks gate 26 and the V.C.O. starts to produce an F.M. signal This is compared in phase detector 17 with the L.O. 16 output Acosw 0 t to give - Csin (¢Át<SP>2</SP>) where Á=2#(df/dt). k cycles of this output are counted at 33 whence a signal is produced terminating a pulse from generator 31 started by signal #T. Said pulse gates through 30 a number of cycles from L.O. 16 to a counter 29 indicative of the time for the k cycles to occur. This number is compared at 34 with a number in register 35 indicating a desired rate of F.M. and the comparison result used via integrator 67 to provide the control signal for the V.C.O. for the next chirp pulse. The timing and switching input T is produced by a mono circuit 24 triggered by a threshold detector 22 of the detector 20 output, via a gate 23 enabled by the radar sync pulse #S.

Filed: 1920-03-12
Abstract: 168,343. Pericarp Syndicate, Ltd., and Trevor, E. W. J. March 12, 1920. Thrashing-machines.-The fruits of the oil palm and the like are separated from the spikes or fronds by agitating on a moving sieve, or by subjecting them first to a beating or agitating operation and then passing them over the moving sieve. An endless travelling band sieve C forms the bottom of a trough E into which the fronds are fed by an elevator D, and in which agitating- arms B<5>, B<6>, B' revolve. Rollers F<2> bearing spikes or projections are arranged at both sides of the upper part of the sieve C and continue the agitation of the material. The fruits passing through the sieve are guided by an inclined plate J to the conveyer H<3> and delivered through a shoot J<1>. The stalks remaining on the sieve pass over to a shoot J<2>, which also receives from lateral conveyers G any material carried over by the rollers F. The trough E and arms B<5>, B<6> may be replaced by lateral rollers similar to the rollers F<2>. These may revolve at different speeds. According to the Provisional Specification the action of the sieve may be assisted by an air current, and the progress of the material along the sieve may be accelerated by means of an endless belt carrying ploughs or agitators, by a shaft carrying arms, or by helical projections on the rollers F<2>.

Title: Improvements in or relating to method and apparatus for continuously casting rod
IPC: B22D11/14
Filed: 1942-06-02
Abstract: 561,363. Continuous casting machines. DOEHLER DIE CASTING CO. June 2, 1942, No. 7485. [Class 87 (ii)] [Also in Group XXII] In the continuous casting of rod, the initially molten material is passed through a die tube 23 while this is subjected to a travelling distortion wave which produces a slight reduction in cross-section of the congealing material and thereby reduces friction. The die 23 is made of air hardening or nitrogenized steel or other hard material and is mounted in the bottom of a well 5 submerged in molten zinc-aluminium or other alloy or metal which is kept at about 10‹ F. above its melting point by a thermostat 3 and at a constant level by an automatic supply 4. The solidified metal is drawn up intermittently by rolls 10 driven through a ratchet 12 and variable-throw crank 15 by a motor 17. The die is cooled and distorted by a rotating jacket 27, Fig. 2, which cools only by a longitudinal passage 26 through which cooling fluid is passed from a supply tap 53 by a pipe 43, slip coupling 42, pipe 30a, jacket 54 for cooling lubricant L, and pipe 30, the fluid being returned by a pipe 29, slip coupling 42, and pipe 44. The constantly varying shape of the die reduces the diameter of the solidifying metal rod and so reduces friction. This is also assisted by the high boiling point paraffin or other oil L which flows into the space between the die and the solid rod which it also cools. The die 23 and jacket 54 are rotated by gearing 38, 39, a jointed and telescopic shaft 40, and bevel gears 41, Fig. 1. The rod is received by a holder 19 pivoted at 20 and, after cutting off by a saw (not shown), is delivered to a shoot 21. In a modification, the mould-cooling passage 26, Fig. 6, is annular and is reciprocated axially by linkwork 61, pawls 62 feeding the rod during the upward movement. The rod may have any section desired and may be fed continuously.
