Title: Improvements in or relating to Electromechanical Band Filters.
IPC: H03H9/50
Filed: 1968-05-10
Abstract: 1,160,507. Electro-mechanical filters. SIEMENS A.G. 10 May, 1968 [12 May, 1967], No. 22215/68. Heading H3U. A band filter comprises resonator elements 3, 3<SP>1</SP> formed of metal rods each having a flat longitudinal surface 4, the rods being mounted on a metal base 7 by support wires 6. The end rods 3<SP>1</SP> include, respectively, input and output electrostrictive transducers whereby flexural vibrations introduced by an input signal on wires 1, 2 to one rod 3<SP>1</SP> are transmitted by a coupling wire 10 through the rods 3 to the other rod 3<SP>1</SP> from which an output signal is taken on wires 1<SP>1</SP>, 21. The wire 10 is welded to each of the rods 3, 3<SP>1</SP> in the region of an antinode whilst wires 6 are secured at nodal points. Each rod 3<SP>1</SP> is sub-divided by blocks 12, 12<SP>1</SP>, 13, 13<SP>1</SP> of electrostrictive material arranged in pairs with a gap 14 between the blocks of each pair. The blocks are pre-polarized in the directions 15, 15<SP>1</SP>, 16, 16<SP>1</SP> so that an electric signal causes the blocks on one side of the gaps 14 to contract and those on the other side to expand thereby introducing the flexural vibrations. Attenuation poles may be produced by an additional coupling wire 18  bridging a number of the rods 3. In a modification (Fig. 3, not shown) the flat surfaces 4 are in planes perpendicular to the plane of the base 7.

Title: Improvements in or relating to musical instruments
IPC: G10D3/02
Filed: 1945-08-29
Abstract: 600,854. Musical instruments. PEGRUM, D. H. Aug. 29, 1945, No. 22246. [Classes 13 and 88 (ii)] A means for producing sound waves from a vibrating body or string comprises supporting the vibrating body on a bridge member or frame and communicating the vibrations from the latter to a sound radiator through a mechanical matching device. The radiator may be a diaphragm of comparatively small mass and the amplifier an arrangement of levers. In the form applied to a piano, the strings P, Fig. 2, are mounted on a frame F which is flexibly supported on a bracket S6 attached to a heavy mounting M5. This frame is free at its upper end and its vibrations are communicated through a rod N to a lever L pivoted on a spring S7 and having its free end connected to a diaphragm D. In a modified form more suitable for the higher frequencies the vibrations of the frame are communicated through a bell crank to a coil spring which is made to twist when compressed and thereby to actuate the diaphragm through a radial lever, Fig. 3 (not shown). In further modifications a bridge piece is attached to the strings and connected through a lever to a light soundboard, Fig. 4 (not shown).

Title: Improvements in and relating to the production of corrosion-resistant surfaces on copper and copper-alloy surfaces
IPC: C23C22/24
Filed: 1945-08-30
Abstract: In a process for producing, and an article possessing, a cupriferous surface with increased resistance to corrosion, the cupriferous surface is subjected to the action of an aqueous solution containing chromic acid and zinc ions, between 0.075 and 175 gm. per litre of total chromic acid being dissolved therein, and which solution is saturated with respect to zinc ions, so that any further zinc compound added remains undissolved.  In practice the ratio of zinc to chromic acid in the treating solution preferably corresponds to a Zn O:Cr O3 ratio of between 25 : 75 and 35 : 65.  Examples are given of the method of producing satisfactory solutions by dissolving flake chromic acid (Cr O3) in water followed by the addition a zinc oxide, hydroxide or carbonate or mixtures thereof until some zinc compound remains undissolved.  The treatment may consist of a single dip in a strong solution containing between 8.5 and 175 gm./litre, and preferably between 15 and 90 gm./litre, of Cr O3; or a dip in a strong followed by dipping in a weaker solution containing 0.075 to 15 gm./litre, and preferably 0.8 to 2.5 gm./litre, of Cr O3; or for smoothly polished, dense surfaces a dip in the weaker solution only. Where the two-dip process is employed one of the solutions need not be saturated with respect to zinc ions, and if this applies to the first (stronger) solution a water rinse should be interposed between the dips.  The solutions are preferably used hot, between 190 degrees F. and their boiling point, and the treatment may be applied to superficial cupriferous surfaces on ferrous base metals.  The treatment also provides a good foundation for a subsequent organic coating of e.g. paint, lacquer or enamel.  Spraying or washing with the solution(s) may replace dipping.  U.S.A. Specification 2,217,921 is referred to.

The handle of the machine supports a tank 14 containing cleaning liquid which is delivered to the boss 35 by a pipe 15. The boss is slotted for passage of the liquid and is formed underneath with guides 42 to direct the liquid towards the floor. The brush ring 6 is formed with flanges 32, 34, between which brushes are held detachably by means of leaf springs 40 adapted to press the brushes against the grooved edge of the flange 32. The reverse side of the ring is adapted to carry a pad 43 over which sand-paper or a polishing cloth may be stretched by means of a hoop 44. The hoop may be a tight fit on the brush ring, or may be split and provided with flanges drawn together by screw means. For waxing the floor, there may be provided in place of the sand-paper or polishing cloth two layers of burlap or other porous material, between which wax paste is placed, the wax extruding gradually as the brush-ring rotates.

Abstract: 1500395 Relay energizing circuit SCHLEICHER GmbH & CO RELAIS-WERKE KG 29 May 1975 [6 June 1974] 23397/75 Heading H3T A relay Re energizing circuit as shown has the property that it energizes the relay momentarily either when a supply voltage Uv is applied to the circuit or when the voltage is removed from the circuit depending upon which of two contact-pairs AN and AB is bridged, respectively. In effect the circuit shown acts as a differentiator causing a positive voltage pulse to be applied across the relay when the supply voltage is connected and a negative voltage pulse when the supply is disconnected, one of these pulses being shunted around the relay by one of the diodes. Connection of the supply voltage Uv, which may be either A.C. or D.C., causes capacitors C3 and C4 to charge via a resistor R1 and either relay winding Re or a diode Gr3. Capacitors C1 and C2 also charge, the potential across C I being limited to about 0À6 v by a diode Gr2, thereby maintaining a transistor T off. With all four capacitors charged disconnection of the supply voltage Uv causes C2, C3 and C4 to discharge initially via a resistor R2 and the baseemitter path of transistor T and then, when T becomes conductive, via R3 which is considerably smaller than R4. A potentiometer R6 varies the relay "on" time.
