Filed: 1947-12-11
Abstract: 645,758. Magnetic induction accelerators. AKT.-GES. BROWN, BOVERI, & CIE. Dec. 11, 1947, No. 32700. Convention date, Dec. 11, 1946. [Class 39 (i)] In a betation, for introducing the electrons into, or abstracting them from, the equilibrium orbit, the radius of the equilibrium circle is changed simultaneously with a displacement of its contre, so that the old and new circles of equilibrium still pass through the same point at one place only in the accelerating tube, thereby preserving the symmetrical distribution of the radial stabilizing forces at that point produced for example by the magnetic guide field for both the old and new circles. As shown in Fig. 6, the anticathode is located at E, and the electron stream is brought from the old circle 10<SP>1</SP> to the new circle of equilibrium 11<SP>1</SP>. At point F the stabilizing forces for the old and new circles are the same. With E representing the location of the electron source, 11<SP>1</SP> is the old and 10<SP>1</SP> the new equilibrium circle. The transition from the old to the new circle is accomplished by an auxiliary coil which is wound to produce oppositely directed fields at points on the orbit situated at opposite ends of a diameter. The radius of the orbit is simultaneously changed by saturating the guide field, or by introducing a phase displacement between the guide field and the induction field.

[Class 3 (i).] An advertising apparatus comprises a magazine of independent display panels 14 which are raised in turn into a display position by a vertically reciprocating frame 4 sliding on rods 12. The frame 4 has a cross-slot 5 in which slides a pin 6 on a disc 7 rotated by a motor 8. The frame in its upward motion first transfers a panel from the front of the inclined magazine 13 to rests 18, then on the next rise to rests 19 at the top of inclines 20 and on the following rise picks the panel up and displays it above the casing 1. The displayed panel descends with the falling frame and is transferred on to the inclines 20 and finally reaches the back of the magazine 13. The frame 4 engages the panels 14 by grippers 16, 16<1>, 16<11>, consisting of spring tongues pivoted to the frame and bearing at one end against the wall of the casing 1. The upper end of each tongue enters into the top bar 15 of the panel 14, which bar is formed as an inverted U. The rests 18 consist of fixed hooks over which the bar 15 snaps as the frame 4 rises and on which it is left as the frame falls. The grippers 16<1> then reach the panel and lift it to the rests 19, and the grippers 16<11> eventually pick it up for display. In descending from display the panel lower edge strikes a pivoted deflector 22 which causes the bar 15 to lie on top of the inclines 20 just before release by the grippers 16<11>. The panel slips down the inclines 20 but is held up at the bottom by spring- controlled stops 24. Arms 27 rigidly projecting from the frame 4 displace the stops 24 when the frame reaches its upper position, and receive the panels to deposit them at the back of the magazine 13.
