Title: Process for the production of radioactive technetium-99m
IPC: C22B61/00
Filed: 1968-04-16
Abstract: 1,207,246. Separation of radio-isotopes. UNION CARBIDE CORP. 16 April, 1968 [16 June, 1967], No. 17816/68. Heading G6R. Radio-active technetium 99m is separated from a solution of molybdenum 99 by forming a slurry of the solution with an oxidized zirconium compound, adjusting the pH of the slurry to 2 to 7, heating to above 40 C., and selectively extracting Tc 99m from the slurry solids with a solvent. The radio-active Mo 99 solution may be obtained from neutronirradiated molybdenum trioxide, nitrate, sulphate, or acetylacetone, or molybdenum metal. The solution is mixed with a slurry of hydrous zirconium oxide which has been oxidized with bromine or chlorine water, potassium permanganate or chlorate, hydrogen peroxide, or benzoyl peroxide. The slurry is drained in a column, washed, and Tc 99m eluted with isotonic saline, methyl ethyl ketone, or an aqueous solution of an inorganic acid. If the column and isotonic saline are sterilized, solutions suitable for medical use are obtained.

Sights.-Relates to sights mounted on the guncradle and having means for adjusting the angle of tangent elevation to compensate for decreased muzzle-velocity due to erosion. According to the invention, a secondary sight-bar, carrying the sight, is angularly adjusted relatively to the sight-bar, which is operated by the ordinary sight-elevating gear, by means of cam mechanism arranged between the two bars. In the construction shown, the two bars B, C are mounted by the same pivot a<3> on a bracket a<2> fixed to the cradle A. The sight-bar B is elevated by the ordinary gear. d<1>. The secondary sight-bar C is connected to the bar B by a link H, at one end, c<2>, pivoted to the bar C, and at the other having a cross-pin g', Fig. 4, engaging a circular camslot f<1> in a block F mounted on the bar B. A rod J connects the link H to the bracket a<2> so that when the sight-bar is elevated the pin g' is caused to travel along the slot f<1>. The radius of curvature of the slot f<1> is equal to the length of the link H, and is normally concentric with the pivot c<2> so that the two bars remain parallel. The block F can be angularly adjusted by means of worm-gearing K, Fig. 4, so that the slot f<1> is not concentric with the pivot c<2>. The secondary sight-bar C will then receive an angular adjustment relatively to the bar B when the latter is elevated by the gear d<1>.

Abstract: 784,351. Impulse transmitters. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. May 24, 1956 [June 25, 1955], No. 18424/55. Class 40 (4). An impulse train is generated by means of an impulsing cam which is driven by a mechanism on its return from a set to an initial position, an inter-train pause being produced by mounting the impulsing cam on a member having lost motion so that the cam moves away from its impulsing springs when the mechanism is set and moves back to engage the springs during an initial part of the return movement of the mechanism. The mechanism shown in Fig. 1 has a finger-plate 13 secured to a shaft 14 passing through a base plate 10 and a housing 11 which mounts a finger-plate restoring spring and a number plate. Springs 42, 43 are controlled by an off-normal cam 18. A gear 17 on the shaft 14 drives a speed regulator of the governor weight type through a one-way spring clutch 31 and pinion 21. The impulsing cam 33 is fast with a pinion 22 pivoted on an ear 35 of a disc 36 mounted on shaft 14 but frictional coupled to it by springs 37, 38, Fig. 2, lodged inside a circular flange 39 on the disc. The disc 36 can move between two abutments, one of which 49 is shown. When the finger plate is set, disc 36 moves with shaft 14 to strike one abutment after which cam 33 is driven, but in a position out of range of the impulsing springs 40; whereas when the finger plate returns, under control of the regulator, disc 36 must be moved by shaft 14 back to abutment 49 to carry cam 33 within range of springs 40 to produce an impulse train. An alternative means of clutching disc 36 to shaft 14 comprises the use of a second gear wheel loosely mounted on shaft 14 to engage pinion 22 but not pinion 21 (Figs. 3 and 4, not shown). The extra gear wheel is connected by a spring to gear wheel 17 so that the teeth of the two gear wheels pinch the teeth of pinion 22, the resulting friction being sufficient to clutch the shaft to the disc.
