Title: Improvements relating to aerials
IPC: H01Q1/20
Filed: 1953-12-21
Abstract: 748,318. Aerials. ANTIFERENCE, Ltd., and BEST, N. M. Nov. 22,1954 [Dec. 21, 1953], No. 35525/53. Class 40 (7). To avoid a high-frequencyrod aerial element being caused to vibrate by the wind and producing an audible howling effect at the receiver the rod element is provided with a loosely mounted mass at or near its free end. The inertia of the mass tends to oppose the movement of the element and damps vibration. In a first embodiment the rod element is tubular and has a plug or cork driven into the free end to leave a cavity about half an inch deep. Into this cavity is put a steel ballbearing, a lead shot, or piece of brass, and the cavity is then sealed as by a second plug in such a way as to allow the inserted mass to have free movement (Fig. 1, not shown). Fig. 2 shows the free end of a tubular rod element 1 in which has been inserted a loading device. The device consists of a plug 5, which may be of plastic material, having a cavity in which the mass 3 is loosely held and into which it may be forced through aperture 6. For a solid rod element 7 a loose ring 8 can be used held in position by collars 9 spaced to allow the required movement.

Filed: 1971-08-02
Abstract: 1323235 Electron beam furnaces AIRCO Inc 2 Aug 1971 [29 Sept 1970] 36152/71 Heading H1D An electron beam furnace includes gun 11, four solenoidal coils 13, 14, 15, (16) arranged with axes forming quadrangle about the beam path, each coil having a core (e.g. 17, 19) of low magnetic reluctance material and control circuit 21 for energizing oppositely disposed coils to produce force lines in same direction, the energizing current being controllable variable to vary the point of impact on target 24. The coils of each pair may be connected in series or parallel, the polarity being such as to produce a field in the same direction, and preferably the length is #twice the diameter and have a Œ10% field uniformity. Figs. 2 and 3 (not shown) indicate the force lines on individual excitation of opposing pairs and Fig. 4 (not shown), the combined field. The coils and cores may all be equal in length, or form a rectangular or other quadrangular geometry depending on furnace geometry or sweep required. Molten target 24 in elongated container 26 may be cooled by coolant in passages 27 to form solidified skull 28. The material 28 flows along the hearth from a launcher and the level may be controlled by a weir, such as for purification of iron and nickel alloys and Co, Ta, Ti, Zr. Tundishes, siphons and ladles for material exit and entry are also mentioned. The electron beam or a plurality of beams may prevent solidification in transit through the low pressure atmospheres such as required for differential vaporization for purification for example. Gun emitter 32 between supports 33, 34 produces a ribbon shaped, narrow oval cross-section beam reflected on three sides by shaper 36 insulated by strips 37, 38. The circumferential field produced by the D.C. heating current causes a non- normal orientation of the emitted beam, deflected by magnets 48, 49 with polepieces 47. Vapour barrier 52 also enables the two compartments to be separately pumped. Wedge shaped polepieces 53 with em. coils effect a 150 degree deflection.

Title: Process for the production of lactic acid and derivatives
IPC: C07C51/377
Filed: 1956-12-03
Abstract: Lactic acid is prepared by contacting propylene at a temperature below about 40 DEG  C. with an oxidizing medium containing at least one mol. of dinitrogen tetroxide (nitrogen dioxide), dinitrogen trioxide or a mixture thereof for each mol. of propylene, and reacting the resulting reaction products with at least one mol. of nitric acid for each mol. of propylene.  The nitric acid may be present in the oxidizing medium or may subsequently be added to the reaction products or, preferably, the reaction products added to it. Nitric acid with an HNO3 concentration of 25-100 per cent by weight is suitable.  It may be formed in situ, e.g. by reaction of added water with N2O4.  When the oxidizing medium contains both nitric acid and the oxidizing agent, reaction temperatures below about 10 DEG  C. are desirable.  When two steps are used, the first is preferably effected below about 10 DEG  C., but the step employing nitric acid may be effected at temperatures as high as 100 DEG  C. An hydrolysis step may be necessary to obtain maximum yield of lactic acid.  The lactic acid may be dehydrated to acrylic acid and/or esterified, e.g. with alkanols, or esterified then dehydrated.  Dehydration may be with P2O5 or by the methods described in Specification 409,733, [Group IV].  An example is given in which the lactic acid is isolated as the calcium salt.
