Title: Improvements in high-frequency resonant systems
IPC: H03H7/01
Filed: 1935-11-05
Abstract: 463,202. High-frequency transformers. JOHNSON LABORATORIES, Inc. Nov. 5, 1935, No. 30599. Convention date, Aug. 10. [Class 38 (ii)] [Also in Group XL] A high-frequency coupling system comprises three resonant circuits tuned to the same frequency, the inductances being so arranged that there is zero magnetic coupling between two inductances and a variable magnetic coupling between the third and one of the other two. Figs. 1 and 2 show one arrangement of three inductances 1, 5, 10 with powdered iron cores and mounted on a base 3, the variable condensers 14, 15, 16 being mounted on the underside. The middle inductance is pivotally mounted on a bracket 7 having a pointer 9, the arrangement being such that rotation of the bracket varies the coupling between 5 and 10 considerably, with only small changes in coupling between 1 and 5. A typical circuit arrangement embodying this arrangement is shown in Fig. 3, and Fig. 5 shows the coupling system mounted in a screening container 25, a valve holder 24 being mounted by a bracket on the base member 3. In a modification, Figs. 6 and 7 (not shown), the inductances 1 and 10 are oppositely inclined, each at an angle of 60‹ to the base 3 ; with this arrangement, the coupling between 1 and 5 varies to a greater degree as coil 5 is swinging round, the variation being still less than that between 5 and 10. Figs. 8 and 9 show a modified method of mounting the central coil 5 by means of a ring 31, on which the bracket 7 is pivotally mounted, the ring being also rotatable by loosening screw clamps 32. The reduction in gain consequent on the use of three loose-coupled circuits may be offset by increasing the inductance of coil 1 to increase its resonant impedance. The object of the invention is to obtain a flattopped band-pass characteristic with steeply sloping sides. Specifications 403,368, and 446,743, [Group XXXVI], are referred to.

The device is placed across the rails with insulated contacts 12 carried by a graduated slide 10 engaging the surface of one rail while a guide fast with a bracket 2 on the other end of the beam engages the inner surface of the other rail. A graduated cam member 4 engaging the upper surface of this rail. The first rail is levelled up in known manner, and the sleepers marked with the amount the rail has to be raised or lowered adjacent the sleepers. The rod 10 is then raised or lowered to compensate' for the known cant between the rails and clamped by the fly-nut 11. The plate 4 is then turned about its axis 5 to bring the beam level and the indication at the pointer 8 gives the amount by which the adjacent rail must be raised or lowered, which amount must be added to or subtracted from' that marked on the sleepers at the other end. In a modification the cam plate is dispensed with and a screwed spindle arranged to be moved up and down while the slide 10 is replaced by a tubular member. In a further modification the cross member is formed of wood and has at one end a slide moved up and down by a rack and quadrant and at the other a rod which may be slid up and down and clamped in any position.

Filed: 1961-08-28
Abstract: 952,384. Rotary distributers; contactmembers for switches. ALACRA Ltd. Oct. 11, 1962 [Aug. 28, 1961], No. 30898/61. Heading H2B. In a switch of the kind wherein a brush 16 wipes over rigid contacts 12 means are provided to lift the brush should the direction of relative motion be reversed. Brush 16 is mounted on a spindle 20 and driven to wipe over a number of contacts 12 embedded in sectors 11 on a fixed disc 10. A spring 21 tends to lift brush 16 away from contacts 12 but when the roller 28 engages a sector 11 it rotates lever 24 about pivot 26 such that a pin 23 turns a forked arm 22 fixed on spindle 20 and moves brush 16 against contact 12. The roller 28 is carried by a member 30 articulated at 31 as shown for pivotal movement one way only. Thus, if the direction of relative movement between brush 16 and contact 12 is reversed, the member 30 pivots and brush 16 is maintained clear of sectors 11 (Fig. 3, not shown). Spindle 20 also carries a pick-up brush 32 which bears on a continuous contact ring or a second set of contact sectors. The disc 10 may rotate instead of the brushes, and the contacts may be on its periphery instead of a side face. The brushes may be normally in position to engage the contacts and lifted away by the roller striking a sector during reverse rotation.
