Abstract: 322,680. Radiologie Akt.-Ges., and Bennemann, F. Jan. 19, 1929. R÷ntgen-ray tubes having a round focal spot which appears substantially, as an ellipse when viewed in the direction of propagation of the R÷ntgen rays,. has the side segments situated at the extremities of the major axis, screened off, in order to produce a defined focal spot. In one example, Fig. 3, a cylindrical copper screen 8 is secured to an anticathode 5, the upper surface of which is inclined at an acute angle, e.g. 15‹-30‹, to the axis of the tube. A slit 9 having radial edges and situated in the thickest part of the eccentrically bored screen allows propagation of raysfrom only the trapeze-shaped portion 6<c>, injurious rays emerging from the segments 6<a>, 6b being screened off. In a modification, Fig. 6, tungsten screening wings 11, situated radially to the anticathode, furnish a comparatively long path for rays from the side segments 6a, 6b. The wings 11 may have extensions situated in slits in the anticathode and secured therein by binding wires. In a further construction, Fig. 9, an opening 15 in a screening cylinder 8<a> is provided for the cathode rays. Loading of the tube may be, increased by forming a wedge-shaped groove 14 in the surface of the anticathode.

Abstract: 876,161. Radiant heating elements. GAS COUNCIL. Jan. 15, 1960 [Jan. 24, 1959], No. 2688/59. Class 51 (1). The forward part 1 of the cylindrical casing of a radiant heating element, closed at its forward end, is mounted on a furnace by a flange 4 and connected to an intermediate casing part 2 carrying a flue outlet 6. A combustion chamber, converging at 22 towards its outlet 23, is mounted by flanges 9 to leave an annular clearance 19 within the casing part 2, and a cup 3 carrying a burner mixing tube 14 closes the rear end of the element. Within the cvlindrical casing 1, a coaxial sleeve 24 is located by radial studs 27 and axially projecting studs 28, 29 so that it is nearer the combustion chamber body than the closed end of the radiant tube. Combustion products issuing from the burner outlet 23 into the sleeve 24 induce a recirculation of the gases along the space 26 between the sleeve 24 and casing 1 and inwards between the spacers 29. Excess gases are withdrawn through annular space 19 round the combustion chamber to the flue outlet 6. The burner 14 and cap 3 can be replaced as a unit, the combustion chamber can be readily removed and replaced, and by removing the intermediate casing part 2, the sleeve 24 can be removed without removing the radiant casing part 1 from the furnace.
