Title: Improvements in or relating to nuclear reactors
IPC: G21C1/14
Filed: 1961-12-13
Abstract: 1,003,215. Cooling reactors. AMERICAN MACHINE & FOUNDRY CO. Dec. 13, 1961 [Dec. 23, 1960], No. 44659/61. Drawings to Specification. Heading G6C. In a swimming pool reactor the fuel is isolated from the pool within an aluminium housing which provides a re-entrant path for a flow of pressurized coolant liquid through the fuel. The fuel plates are cylindrical and are formed of uranium clad in aluminium. The plates are reversibly mounted so as to provide a higher fuel burn-up rate. Beams of fast and thermal neutrons are provided along horizontal paths from the core through apertures in the concrete lining of the pool. Pneumatic and hydraulically operated sample carriers permit irradiation of samples in the high neutron flux zones of the core. The coolant liquid is circulated in a closed circuit through a degasifier and demineralizer.

Title: Polymers
IPC: H01G13/02
Filed: 1962-11-27
Abstract: Polymers of methyl methacrylate containing a substantial proportion of syndiotactic units are made by effecting the polymerization of the monomer in the presence of an anionic polymerization initiator and in the presence of at least 1 mole of a dipolar aprotic solvent per mole of anionic initiator.  The term dipolar aprotic solvent is defined in Quarterly Reviews 16 163 (1962).  The Specification gives extensive lists of suitable aprotic solvents.  Preferred classes of compounds are dialkyl sulphoxides, oxides of heterocyclic amines, cyclic derivatives of carbonic acid, aliphatic N,N-disubstituted amides, heterocyclic ketones, cyclic derivatives of N,N1-disubstituted urea, heterocyclic compounds containing 2 non-adjacent nitrogen atoms in a heterocyclic ring, and derivatives of phosphoric triamide. The anionic initiator may be fluorenyl lithium, triphenyl-methyl sodium, triphenyl-methyl potassium, butyl lithium, or amyl sodium. The aprotic solvent may itself act as the polymerization medium. Other inert solvent may be present such as hydrocarbons and ethers.  The polymerization may be effected below - 40 DEG  C.  The polymerization is terminated by addition of acid, and the polymer recovered by conventional techniques.  The monomer is dried before polymerization.

A doped zone in a semi-conductor body is produced by diffusing from a layer of doping material incorporated in an oxide of the semiconductor body by heating in air to more than 1000‹ C. The layer may be produced as described in Specification 1,014,287 by directing on to the body a mixture of water vapour, a first substance which splits off hydrogen and/or alkali ions and volatilizes and a second substance containing the doping material; such a mixture may consist of water or hydrogen peroxide, hydrochloric acid and boric acid and/or aluminium chloride. In one example, the layer is produced by passing a current of nitrogen containing boron iodide through a quartz tube containing silicon discs, followed by a current of oxygen. Alternatively, a flow of B 2 O 3  in oxygen or P 2 O 5  in oxygen may be used. Fig. 1 shows a suitable furnace for the diffusion process. Silicon discs 2 with the doped oxide layer are heated to 1280‹ C. in a quartz tube 3 which is closed by paper or sintered steel or nickel filters 6 which allow exchange of air.

Abstract: 1,171,235. Interconnected power supplies. FRIDEN Inc. 9 Oct., 1967 [1 Feb., 1967], No. 46053/67. Heading H3T. Two power supplies feed current through loops which are electrically independent of one another, the supplies being connected by means of a diode and resistor in series across one supply with the junction point connected to one side of the other supply, the diode being forwardly biased by the first supply. In Fig. 1 a driver stage 11, which may be the output stage of an integrated circuit, feeds a switching stage 30 for operating a solenoid 34, e.g. of a print hammer, tape punch, relay or clutch. Each stage has its own power supply 14, 36, the former being earthed at 15 but the latter being floating. Across the supply 14 is a conducting diode 43 and resistor 42, the junction of these being connected to one side of the supply 36. The two supplies are otherwise coupled only through the base-emitter junction of the transistor 30, and switching transients in the latter circuit are not fed back to the earlier stage since changes in the voltages of the two sources do not affect the conduction in the diode 43. This is also unaffected by the turning on and off of the two transistors. A plurality of switching stages 30 may be fed from the same driver stage 11 containing a plurality of transistors 20. The resistor 40 may be replaced by a capacitor. The conductivity types of the transistors may be interchanged, with consequent reversal of the polarities of the supplies and of the diodes 35, 43 (Fig. 2, not shown). The emitter of transistor 30 may be earthed instead of that of transistor 20.

Abstract: 1,070,182. Circuits employing bi-stable magnetic elements. WESTERN ELECTRIC CO. Inc. Nov. 28, 1963 [Nov. 30, 1962], No. 47025/63. Heading H3B. By coincidently energizing a selected pair of conductors 46-19 from current sources 40-43 so that the stable flux distribution of a magnetic device 10-13 is changed, binary digits each represented by the presence or absence of continuous current in respective signal conductors 72 are converted into single identifying pulses which are applied to a utilization circuit 60 through output conductors 80-83. The magnetic devices are formed of square loop material and each comprise drive logs 20, 20<SP>1</SP>, shunt legs 21, 21<SP>1</SP> and apertured cross legs 22, the apartures 30-33 being threaded by the signal and output conductors and the apertures 35 threaded by control conductors 70. The devices are initially magnetized in the clockwise sense, Fig. 2, by a reset pulse in a conductor 44. When identifying pulses are required, the flux distribution in the magnetic device selected is switched by concident currents in a pair of the conductors 46-49, the remanent flux through the drive legs 20, 20<SP>1</SP> then being reversed as shown in Fig. 3. As a result no nett flux is present in the cross legs 22, the internal flux distribution being balanced about the apertures by the action of the short-circuited control conductors. If a signal conductor is not carrying current when a magnetic device is switched, the nett flux about the associated aperture is zero as in the case of apertures 30, 33, Fig. 3. Consequently no voltage is induced in the flux transistion period in the associated output conductor which passes in figure-of-eight manner about the magnetic material on each side of the aperture. If however a signal conductor is carrying current, a resultant flux about an aperture in the clockwise direction is obtained as in the case of apertures 31, 32. Since a greater charge of flux occurs on one side of the apertures than on the other, a resultant voltage pulse is produced in the associated output conductor. Subsequently the device is restored to its initial flux condition by a reset pulse. Repeated operation enables a change of binary digits in the signal conductors to be detected. Preferably the cross-sections of the drive and shunt legs are equal and their sum equal to the crosssection of the cross legs. In a modification one shunt leg and one cross leg may.be omitted.
