Abstract: 1,242,533. Cooling reactors. ATOMIC POWER CONSTRUCTIONS Ltd. 15 Aug., 1968 [15 Aug., 1967], No. 37418/67. Heading G6C. In an integral gas cooled, nuclear reactor an independent heat: exchanger within the pressure vessel is used to absorb the reactor heat during shut-down. The turbines 6, 7 are supplied with steam from the heat exchangers 2, 3 in the reactor coolant gas duct 1. During reactor shut-down, the reactor heat is removed by the exchanger 4 and may either be dumped or fed into the turbines or feed-water. Convection circulation of the gas is also effected by the exchanger 4. The secondary flow through 4 may be increased in response to the main turbine throttle closure. In an alternative arrangement, the exchangers 4 are mounted in ducts separate from those containing 2 and 3 and the flow of coolant gas through the ducts is controlled by separately adjustable valves. In this case the exchanger 4 is exposed to forced gas flow during shut-down.

Abstract: 1309687 Uses of luminescence NUCLEARCHICAGO GROUP 6 Aug 1970 [8 Aug 1969] 37926/70 Heading C4S [Also in Divisions H1 and H4] A gamma-ray camera comprises a relatively thick -scintillation crystal 11, Fig. 1, a glass cover-plate 12, fibre optics 20, and image intensifiers 30, 40 and 50 each including an electron emitting cathode and a light emitting phosphor anode and coupled together with fibre optics, the centroid of the resulting intensified relatively large light spot corresponding to an incident gamma-ray being detected by a position-sensitive photo-diode 60 which has four output electrodes nd a common base electrode. The output signals from the photo-diode may be designated (x+), (x-), (y+) and (y-) and their respective magnitudes are such that a signal corresponding to (x+) - (x -) is proportional to the co-ordinate of the centroid of the light spot produced on phosphor anode 54, and (y+ ) - (y-) is proportional to the y coordinate. The sum of all four outputs is proportional to the intensity of the light spot. The fraction of energy going into the x and y co-ordinate signals either varies as a function of the co-ordinate of the centroid of the light spot or is constant depending upon the form of the photo-diode. When using the former type, the difference signals are normalized to produce intensity and position independent co-ordinates by computing the values and when using the latter type of diode the values where Z = (x + ) + (x - ) + (y + ) + (y - ), are computed. These computed values are displayed on a C.R.T. which is unblanked in response to the output of a pulse height analyser, or recorded on a video tape. When displayed on a C.R.T. a sequence of pulse displays may be integrated or photographic film. The sensitivity of the camera is good because a relatively thick scintillation crystal is used, e.g. 1“ cm. thick sodium iodine or casium iodine, both of which may be activated with thallium, and the resolution is good because the centroid of the relatively large light spot on the output phosphor screen is computed. If a curved scintillation crystal is used the fibre optics 20 are not required (Fig. 2, not shown). The scintillation crystal may be located inside the intensifier tube envelope with a photo-cathode deposited directly thereon (Fig. 3, not snown). Instead of the intensifier arrangement 30, 40, 50 of Fig. 1 a single intensifier may be used having electron amplifying electrodes (Fig. 4, not shown).

Title: Improvements in or relating to electrical distortion equalizers
IPC: H04N5/20
Filed: 1957-12-06
Abstract: 847,849. Electrical signal transmission systems. WESTERN ELECTRIC CO. Inc. Dec. 6, 1957 [Dec. 17, 1956], No. 38006/67. Class 40 (4). [Also in Groups XL (b) and XL (c)] An equalizing network for correcting compression or expansion of a signal comprises two parallel paths, one of which contains one or more non-linear impedances designed to produce a correcting voltage for application to the output from the main path. The paths are associated with attenuators or amplifiers which proportion the amplitudes of the signals in the two paths. The equalizer may be used to correct distortion consisting in compression or expansion of the positive or negative excursions of a signal, e.g. grey scale or luminance distortion in television circuits. In the balanced equalizing network of Fig. 1 the main path contains an amplifier 12 which may be associated with a phase-changing network 11 for correcting phase distortion in the amplifier. The total phase change in the main path is either zero or 180 degrees at a selected frequency, e.g. the frequency of the colour carrier in a colour television circuit. Two signals derived in parallel from the input are each applied across a series arrangements of a pair of rectifiers respectively 18, 19 and 22, 23 connected in one case with anodes back to back and in the other with cathodes back to back. Voltages derived from tapped resistors 21, 26 connected between the pairs of rectifiers are applied to a tapped resistor 17 shunted across the output. Resistors 21, 26 control the compression or expansion of the positive and negative excursions of the signal and resistor 17 controls the magnitude of the correction. The rectifiers may be replaced by non-linear resistors, capacitors or inductors. In a modification (Fig. 2) the circuit is unbalanced and the signal in the control-voltage path is derived from tapping points respectively on the high potential side of the input and output of a 180 degree phase-shift network 28. The main path comprises a further 180 degree phase-shift network 29. The networks 28, 29 also provide amplification. The networks shown in Figs. 3 and 4 are both unbalanced. In the former, phase-shift network 43 compensates phase changes in amplifier 48. The magnitude of the correction is controlled by resistor 49 and the sign of the correction by resistors 57, 62. The network of Fig. 4 uses no amplifier but is provided with an attenuator 65 which may be adjustable to regulate the magnitude of the correction. Specification 847,850 is referred to.

As shown the motor pinion 10 drives the cam 16 via wheels and pinions 11 - 15 and is coupled to a rate regulating balance 35 via a synchronizing system 37. The inner end of the reserve spring 26 is fixed to a spindle 24 which carries a stop pinion 43 and a wheel 23 driven by the ratchet wheel 19. The outer end of the spring is secured to a barrel having a gear 27 to drive the balance, via a train 28-34, and an output element of the movement. When the spring 26 is only lightly wound, each stroke of pawl 40 turns the wheel 19 by two teeth, but as the spring 26 becomes more fully wound, lever 18 which carries the pawl lifts off the cam 16 and each advance of wheel 19 is reduced to one tooth or  zero. The winding and unwinding rates of the reserve spring may be equal when it is nearly fully wound. Unwinding is limited by nose 41 of the pinion 43, which nose rotates geneva wheel 42 until it comes up against stop zone 50 as shown. Overwinding is similarly prevented.

Title: A process for the production of solid boron hydride compounds
IPC: C01B35/18
Filed: 1958-12-01
Abstract: Solid boron hydrides of empirical formula BH0,5 to BH1  are produced by heating a boron compound containing boron, carbon, and hydrogen only, e.g. a hydrocarbon-substituted diborane, or a compound BRR1R11, where R is a hydrocarbon radical, and R1 R11 are hydrocarbon radicals and/or hydrogen, under an elevated pressure of H2 in stoichiometric excess to a temperature exceeding 150 DEG C.  At least one mol H2 must be present for each B-C bond, and preferred conditions are 160-280 DEG C. and 10-400 atms.  The reaction may also be effected in two stages by converting the BRR1R11 compound to a hydrocarbon-substituted diborane with part of the H2, and then converting the diborane with the remainder.  The hydrocarbons formed may be separated from the solid boron hydride by evaporation, or distillation, or the solid boron hydride may be filtered from the hydrocarbon.
