Abstract: 1,079,796. Elastic wave energy coupling. WESTERN ELECTRIC CO. Inc. July 14, 1965 [July 14, 1964], No. 29785/65. Heading H3U. A three-port elastic wave circulator comprises a thin disc 10 of a single crystal of polycrystalline ferromagnetic material of the type exhibiting gyromagnetic resonance, the disc radius being in the order of one wavelength of the elastic wave. The disc 10 is excited in a flexural mode by wave energy represented by vector 13 introduced at a selected port 1, 2 or 3, these ports being formed by strips 14, 15, 16 spaced at 120 degrees around the disc. This flexural mode produces a nodal point at the disc centre and a nodal circle about the centre, the disc being supported at its nodal circle between non-magnetic thin-walled cylinders 11, 12. The disc is magnetized in a direction normal to its surface by magnetic polepieces N, S, the various parameters being such that elastic wave energy introduced at port 1 will be coupled to port 2 with no reflected waves at port 1 and no energy at port 3. The underlying theory is explained.

Title: Improvements in luminous electric discharge tubes for the production of illuminated signs and the like
IPC: H01J17/49
Filed: 1920-10-25
Abstract: 153,004. Schmierer, M. Oct. 25, 1919, [Convention date]. Vacuum tubes.-A cathode in the form of a plane or arched plate is covered in parts by a coating of lac or the like or by a stencil plate, the uncovered parts being illuminated by the negative glow to form a sign. The screen may be of conducting material insulated from the cathode. In the lamp shown, the screen b forms the anode and is covered with lac on the side remote from the cathode except for a small margin around the perforations. The cathode a is lacquered at the back. The discharge takes place from the uncovered parts of the front surface of the screen, through the perforations to the cathode. Direct discharge between the opposing faces of the anode and cathode does not take place owing to the small distance; the back of the screen may, however, be lacquered to prevent this with certainty. When the screen b is connected as anode, only the perforations are illuminated; it may, however, be connected as cathode, in which case the margins around the perforations are illuminated faintly and the perforations themselves more strongly. Alternating current may be used. Letters may be formed by slits, or by a number of separate small apertures. In the latter case, the unlacquered parts of the screen are continuous, and the sign appears continuous or made up of points according to the direction of the current; when the diameter of the holes is small, their centres appear particularly bright. Either of the plates a, b may be divided into several independently connected electrodes to allow different parts of the sign to be switched in or out by hand or automatically. The lamps preferably contain rare gases; a lamp containing neon will work at 100 volts. Several lamps containing different gases may be arranged together to produce colour effects.

Title: Time Sequence Switch
IPC: H01H43/12
Filed: 1966-07-06
Abstract: 1,157,684. Time control of electric circuits. MALLORY TIMERS Ltd. July 6, 1966 [July 6, 1965], No. 30322/66. Heading G3T. [Also in Division H1] A time sequence switch includes means for selecting a particular cycle starting point comprises means for de-energizing a driving motor or a cam shaft of the switch when the shaft reaches a particular cycle starting point, the driving motor being energized intermittently by electrical pulses produced by repeated closure of a switch actuated by a constant speed timer motor. In the time sequence switch illustrated in Fig. 9 a particular cycle starting point is selected by pushing a selected pushbutton 70 to open a pair of contacts connecting a switch 76 with a selected one of the discrete conducting paths 85 to 89 on a printed circuit board 83. The switch 76 is momentarily closed by the operation of the push-button 70 to energize a motor 11 which rapidly drives a wiper arm 90 having a contact 91 wiping a continuous conductor path 84 and spaced contacts 92, 93 wiping the discrete paths 85 to 89. When the contact 92 is on a selected discrete path and the contact 93 on the insulated board 83 the motor 11 is deenergized. After this selection of the cycle starting point the programme is commenced by closing a switch 74 to energize a timer motor 27 driving a cam 78 closing contacts 77 for intermittently energizing the motor 11 which actuates control cams 31 Fig. 1 (not shown) controlling programming contacts. The period of each energization of the motor 11 is determined by the duration of the closure by a toothed cam 80 driven by the motor 11 of holding contacts 79 in parallel with the contacts 77. In an alternative switch the cycle starting point is selected by setting a rotary wiper assembly 50, Fig. 8 so that three of four discrete conducting paths 52 to 55 are connected to a continuous conducting path 51 and the fourth, e.g. the path 52, is disconnected therefrom. The paths 52 to 55 are connected respectively to paths 62, 47, 61, and 60 engaged by contacts 64, 65 of a wiper arm 24, which also has a contact 63 engaging a continuous path 59 and is carried by the switch spindle 21 driven, by the motor 11. Thus when the motor 11 is energized the wiper arm 24 will turn until the contact 64 is on the path 62 connected to the open circuited path 52. When the motor 11 is initially energized its rotor moves axially so that a pinion 13 Fig.2 (not shown) thereon is brought into driving engagement with a gear train for driving the shaft 21 carrying the wiper arm 24 or 90 and operating the cam actuated contacts (not shown) of the sequence switch.
