Title: Improvements in and relating to electromagnetic solenoid relays with pneumatic stroke retardation
Inventor: PRIESEMUTH WOLFGANG
IPC: H01H51/34
Filed: 1957-09-09
Abstract: 846,496. Electromagnetic relays. PRIESEMUTH, W. Sept. 9, 1957 [Sept. 10, 1956; Dec. 5, 1956; Aug. 5, 1957], No. 28327/57. Class 38 (5). When the coil 2 of an electromagnetic relay is energized a piston plunger 5 is attracted into the cylinder in the core 1 against the action of a compression spring 6 and air from the cylinder escapes through the valve 3, 4. When the coil is de-energized the spring returns the plunger but the valve 3, 4 is closed by the suction as it rises so that the operation is delayed as air leaks slowly into the cylinder or is let in through a control vent (not shown). Contacts 8, 9 are operated by a head 7 on the plunger. In Figs. 3 and 4 the relay operates as a self-interrupter for a flickering lamp with normally closed contacts 13, 14 on spring strips 11, 12 in series with the coil 2 and the head 7 slidable on a rod 10 of the plunger 5 against the bias of an adjusting spring 15. On operation the head 7 is held by the ends of the strips 11, 12 until the " ploy " is taken up, when the head is forced between the strips to open the contacts. On release the strips retain the head between them until it is engaged by the top of the plunger. In Fig. 5a a similar interrupter has a head 18 slidable on rod 10 with two arms 19 each passing between two spring contacts 20 and arranged to be forced between buttons on the strips so as to separate the contacts rapidly when the plunger is attracted into the cylinder. In Fig. 8 the relay is mounted in the base of an incandescent lamp which is thereby caused to flicker. The plunger operates, with lost motion, a snap-action arrangement comprising a leaf spring 34 carrying the contacts and a compression spring biasing the leaf spring to either side of a centre position. The coil may be in series or parallel with the lamp and in the latter case double contacts can be used so that the lamp energizing contacts can be arranged to close first.

Title: Improvements in or relating to electromechanical filters
Inventor: RUSSEN ALBERT
IPC: H03H9/50
Filed: 1969-06-05
Abstract: 1,240,237. Electromechanical filters. STANDARD TELEPHONES & CABLES Ltd. 5 June, 1969, No. 28427/69. Heading H3U. An electromechanical filter includes at least two resonators coupled by at least one member constructed to vibrate in a strip-line shear mode of mechanical vibrations. This mode is defined as that wherein bending oscillations simultaneously occur about two diagonal axes of a member, the oscillations being normal to the plane of the member and 180 degrees out of phase. Thus, in the instance where the coupling member is rectangular, vibration modes are situated at the mid-points of its sides. Preferably, the resonators themselves also vibrate in the strip-line shear mode but, alternatively, they may vibrate in the flexural, longitudinal or torsional mode. As shown in Fig. 1, two resonators 1, 2 of metal vibrate in the strip-line shear mode and are coupled by a member 3 which vibrates in the strip-line shear mode. Coupling members 4, 5 join the resonator system to a frame 6. A number of resonator systems 1, 3, 2 may be connected in series (Fig. 2, not shown) or in parallel, Fig. 3. In another embodiment Fig. 4, the frame 6 is omitted and the resonator system 1, 3, 2 is clamped at edge 10 or 11 or at both these edges; alternatively, the system may be clamped at edges 40 and 41 or 42 and 43 or at all these four edges. In the embodiment of Fig. 5, a strip-line shear mode resonator 12 is coupled to four resonator networks (not shown) by strip-line shear mode coupling members 13. Fig. 7 shows how a member of the filter, represented by member 14, may be driven in the strip-line shear mode. This is achieved by mounting on opposite faces of the member drive units 15, 16 of piezoelectric, electrostrictive or magnetostrictive material. In a mass loaded filter, Fig. 8, the resonators 32, 33 (which may have cut-out parts 36) are connected by a coupling member 34 vibrating in strip-line shear mode, this member 34 being loaded by a mass 35. In the embodiment of Fig. 9, the two resonators 21, 22 are connected by three coupling members 23, 24, each vibrating in strip-line shear mode. For very low frequencies the resonators may be apertured as shown by apertures 30 in resonator 25 of Fig. 10A.
