Abstract: 1,242,603. Wave couplings. NIPPON KOKAN K.K. 19 Nov., 1968 [25 Dec., 1967; 25 March, 1968], No. 54747/68. Heading H4J. In apparatus for shifting the propagation of vibratory energy through 90 degrees two transmission elements are connected at right angles at a node, an end boundary of one transmission element is at an antinode and carries a longitudinally vibrating transducer while an end boundary of the other transmission element is at an antinode and discharges longitudinally vibratory energy. A cross-shaped member (Fig. 10) may be regarded as two transmission elements joined at their centres. Each element is one half wavelength long at the frequency to be employed. When driving face A<SP>1</SP> is fitted with a vibratory transducer the amplitudes at A, A<SP>1</SP>, B. B<SP>1</SP> are equal. There may be a third transmission element perpendicular to the other two (Fig. 4) so that energy from an input transducer 1 is transmitted in four different directions parallel to its original direction to be discharged at end faces 13, 14, 15, 16. The reverse is achieved by fixing four transducers (1) Fig. 9 (not shown) to the end faces 13, 14, 15, 16, vibrating them together and discharging the vibratory energy at one of the other end faces. The other free end face is fitted with a reflection plate (22) for the frequency concerned. In another arrangement (Fig. 5), three flanges 18, 19, 20 are spaced one half wavelength apart on a transmission rod 17. The distance between each end face of rod 17 and the neighbouring flange 18 or 20 is one quarter wavelength. The energy from the transducer 1 is derived at the peripheries of the three flanges 18, 19, 20. A flange can be used. for convergence instead of divergence. If a flange 24 (Fig. 8) has a regular polygonal periphery, vibratory transducers 1 may be fitted to flat faces and discharged from one end face of the transmission element 23. The other end face is fitted with a reflector plate 22 or replaced by one more transducer. Alternatively, the vibratory energy may be discharged at the rim of a flange 25 positioned one half wavelength from the flange 24. In another embodiment a rod 33 (Fig. 14) has two supports 32, 40 at nodes and two polygonal flanges 30, 31 at antinodes. Twelve transducers (1) Fig. 15 (not shown) are fixed to each flange 30, 31 at holes 34, 35 &c. The structure of Fig. 14 may be increased by, for example, six stages. The transmission elements may be rods or tubes and the transducer(s) may be of magnetostrictive, electrostrictive or piezoelectric type.

Abstract: 1,175,193. Substation equipment. AGFAGEVAERT A.G. 19 Dec., 1966 [30 Dec., 1965], No. 56722/66. Heading H4K. A switching device comprising a telephone receiving apparatus, a transducer adapted to detect telephone call signals, a capacitor charged in response to one or more call signals and a switch arranged to operate when the charge on the capacitor reaches a predetermined value. In one embodiment an induction coil 9 or a microphone positioned near a conventional receiver picks up signals from the ringer 3. They are rectified at 11 and applied to a capacitor 14. The charge builds up and after a number of ringing signals determined by the setting of a variable resistor 15, a Zener diode 12 breaks down and operates a relay 13 which switches on a heating appliance. Alternatively the relay may start a motor driven sequencer which loops the line and connects an oscillator selected in accordance with the present state of the heating appliance to line. After a time sufficient for the caller to note by the selected frequency the state of the heating appliance, a relay, which will respond to any loud noise made by the caller and switch the state of the appliance, is connected to the line. In a modification (Fig. 8, not shown) this latter relay is replaced by a discriminator in the form of a pair of capacitors which are alternately connected to line under the control of the sequencer. The caller has a portable oscillator with which he can apply an intermittent signal to the line. The discriminator synchronizes with the oscillator, and the charge on one of the capacitors builds up until it operates a relay to switch the state of the appliance. If the wrong sequence of signals is received the charge on the other capacitor builds up first and operation is inhibited.
