Abstract: 966,335. Electromagnets. STANDARD TELEPHONES & CABLES Ltd. Sept. 29, 1961 [Oct. 29, 1960], No. 35240/61. Heading H1P. [Also in Division H3] A klystron is tuned by means of a magneto-strictive element. As shown (Fig. 2) the body of the klystron is attached to a cooling flange 2 (Fig. 2) and the tuning element is connected to the end of a magneto-strictive rod 4. The bar is held at its other end by an adjusting screw 6a in a yoke 3 to which are fastened also magnetostrictive elements la, 16. The operation of these elements is in opposite sense to that of elements 4 and they are attached at their lower end to the cooling flange 2. Hence when a control field is applied to coil 2 the movement of the two types of rod is added to increase the tuning effect at the klystron. Screw 6 is used to set the mean klystron frequency and temperature variations should be arranged to cancel. In a further arrangement a pair of magneto-strictive bars are provided each with its own magnetizing coil 12, 14, Fig. 4, one moving the klystron mounting and the other the klystron tuner. A potentiometer 31 is adjusted by motor 30 responsive to frequency drift to unblock one of tubes rol, ro2 and block the other, thus energizing one of the coils to re-tune the klystron.

Title: An improved electric transformer for use in superposing single-phase control currents or impulses on to alternating current networks
IPC: H02H1/00
Filed: 1931-12-23
Abstract: 385,427. Systems depending on static transformers. LANDIS ET GYR SOC. ANON., 1, Hofstrasse, Zug, Swizterland. Dec. 23, 1931, No. 35516. Convention date, Dec. 24, 1930. [Classes 38 (ii) and 38 (iv).] Relates to apparatus for superposing a single-phase current on a main network for remote control purposes and consists in forming the superposition transformer and neutral point impedance coil system as a constructive unit. A threephase star connected choke 2, 3, 4, Fig. 1, connected to a three-phase network 11, to obtain a neutral point 10, has a core 1 with a fourth limb 9 on which is mounted a coil 8 supplied with singlephase current for the purpose of superimposing a control current on the network. A condenser 17 may be inserted in the control circuit to tune the system to the control frequency. The winding 8 may be distributed over the limbs 5, 6, 7 if desired. In a modification, Fig. 2, for interconnecting two three-phase networks coupled by a delta-star transformer 17 so that the single phase control current flowing in one is transmitted to the other, three windings 26, 27, 28 are mounted on the same limbs as the windings of the star-connected choke connected to the system 11 and these are connected in series between the star point of the transformer secondary 22 connected to the system 21 and a neutral wire 30. If desired, the neutral 30 may be earthed. When the systems 11, 21 are connected through a deltadelta transformer, the windings 26, 27, 28 are star-connected to the conductors of the network 21, preferably through condensers to prevent load currents flowings, the star point being earthed. In a modification of this lastmentioned arrangement, an auto-transformer connection is used instead of two separate star connected windings.
Patent GB-1026770-A (GB)
Title: Glass article and method of treatment
IPC: C03C21/00
Filed: 1964-08-31
Abstract: A glass article is strengthened by thermal tempering followed by chemical tempering. Thermal tempering produces a compressive layer (Fig. 2) extending relatively deeply below the surface, while chemical tempering (Fig. 3) produces a compressive layer which is shallower but has higher modulus of rupture (M.O.R.); the combination of the invention is shown in Fig. 4.  Thermal tempering is performed by heating the glass to between the annealing and softening points, and cooling rapidly, by applying a chilling medium until the surface is rigid. <PICT:1026770/C1/1> <PICT:1026770/C1/2> <PICT:1026770/C1/3> Chilling means include liquid sprays, air baths, and immersion in oil or fused salt baths.  By the chilling operation, a thermal gradient is established, so that in the interior, but not in the surface, viscous flow and strain release proceeds, with consequent release of interior stress.  The glass is then cooled to ambient temperature, thereby eliminating the temperature gradient and developing compressive stresses in the surface layer.  The chemical tempering is performed by substitution of a relatively large ion for a smaller ion in the glass at below the glass strain point; e.g. K+ may be substituted for Na+, or Na+ for Li+.  In examples two glasses were used having the following compositions in per cent by weight: SiO2, 66.1/64.5; Al2O3, 20.0/20.9; Na2O, 8.7/5.0; Li2O, 3.6/3.9; K2O, 0.2/0; MgO, 0.9/4.0; As2O3 + Sb2O3, 0.5/0.8.  Test pieces of one glass were then heated in air to 8000 C.; held 4-5 minutes; quenched in a KNO3 bath at 450 DEG  C. for 20 seconds; cooled to room temperature; and transferred to a molten NaNO3 bath at 400 DEG  C. for four hours.  Test pieces of the other glass were heated to 850 DEG  C.; held 2 1/2 minutes; and immersed in a bath of 85% NaNO3, 15% Na2SO4 for 2 hours at 450 DEG  C. Other glasses that may be treated are comprised of exchangeable alkali metal oxide, 5-25%; Al2O3 and/or ZrO2, 5-25%; balance, essentially SiO2; other glass-making oxides-optionally, up to 20%. Drinking glasses are exemplified.

Title: Fuel elements for nuclear reactors
IPC: G21C3/28
Filed: 1963-09-16
Abstract: 1,048,187. Fuel elements. GESSELLSCHAFT FUR KERNFORSCHUNG m.b.H. Sept. 16, 1963 [Sept. 15, 1962], No. 36425/63. Heading G6C. A nuclear fuel element comprising a ceramic fuel material, e.g. UO2 or PuO2, surrounded by a substantially gas-tight can, also of ceramic material, e.g. BeO, is made by pressing the ceramic materials together in granular form and sintering, the can material being of a grading finer than that of the fuel material by several orders of magnitude, so that after manufacture a compressive force is exerted by the can upon the fuel due to the greater shrinkage of the can material. This has the effect of eliminating the tensile stresses which would otherwise be set up in the can by the gaseous fission products which is important since ceramics, although withstanding very high pressures, will fracture under relatively small tensile stresses. The fuel may be heated in powder form to a temperature at which the powder particles coagulate to form grains and then cooled so that the surface of the grains solidifies while the interior remains plastic. Further cooling causes the interior to shrink upon the solidified surface causing internal voids to be formed which are capable of absorbing a considerable portion of the fission gases formed, thus decreasing the load upon the can. A plurality of these grains may be sintered together to form a fuel unit, preferably using BeO as a bonding agent. The use of BeO improves the sintering of the grains, the bonding of the fuel units and the canning, and the thermal conductivity of the element. Spherically-shaped fuel elements according to the invention can be inserted into a reactor as bulk material, or the elements can be combined with the aid of a bonding agent to form clusters. Spheres of moderator material of the same size as the fuel elements may be added to the clusters.
