Title: Improvements in or relating to electro-transducer and method of making same
IPC: H03H9/17
Filed: 1948-09-21
Abstract: 663,546. Piezo-electric crystals. BRUSH DEVELOPMENT CO. Sept. 21, 1948 [Oct. 11, 1947], No. 24671/48. Class 40 (viii). The electrode connecting wires are attached to the crystal surface by fusing the wire into the surface of the crystal at an angle to the surface and at a point such that it also contacts the electrode. This enables the leads of a multiplate element to be attached after the plates have been assembled and the assembly formed to the desired size and shape. It also makes the use of sharp edged leads unnecessary and avoids the deficiencies of the moisture proofing coatings at these edges. An electrode connecting wire 24, Fig. 1, is heated by passing an electric current through it and the corner of a crystal element of for example Rochelle Salt or primary ammonium phosphate is pushed against it until sufficient of the crystalline material has been melted for the wire to contact the graphite electrode 21. The current is then switched off and the crystalline material sets, firmly holding the wire. One end of the wire is then cut off. The method is applied to a multi-element expander assembly (Fig. 4, not shown), and a flexural assembly (Figs. 5 and 6). In this case gaps are made in the central electrode where the upper electrode lead passes through it and a similar gap is made in the upper electrode for the central electrode lead. A piece of foil or a conductive paint 65 ensures a good connection to the upper electrode and a strip of foil 59 connects upper and lower electrodes. Another multiplate flexing assembly (Fig. 9), has one part 73 of the divided upper electrode connected to one part 74 of the divided lower electrode by a wire 78 fused into the element and in contact with conductors 80 and 81. A multiplate assembly using the invention is made as illustrated in Figs. 11-17 (not shown), by cementing together the electroded surfaces of two plates, using a conductive cement containing silver dust, machining the plates to the desired thickness and rounding the corners, applying the outer electrodes and the electrode leads and then dipping the assembly in a suitable liquid. Specifications 599,865 and 663,547 are referred to.

Title: Improvements in and relating to the manufacture of fibre pulp articles
IPC: D21J3/00
Filed: 1933-09-11
Abstract: 410,383. Moulding pulp. BAUMGARTNER, DR. KATZ & CO., GES., Eiswerder, Spandau, Germany. Sept. 11, 1933, No. 25089. Convention date, Sept. 10, 1932. [Class 87 (ii).] In the manufacture of articles from fibre pulp in moulds with pervious walls, the mould is filled from above with a predetermined amount of pulp at a filling station which is firmly, temporarily and stationarily connected with the mould, the excess water being withdrawn from the pulp by causing an atmospheric pressure difference between the inside of the mould and the outside, after which the mould is similarly connected to a drying station where a heated gaseous medium is passed through the article in the mould. Either the moulds or the filling and drying stations may be the moving parts of the apparatus. By increasing the number of filling-stations, articles may be produced with a number of layers, e.g., an outer layer of cellulose and the inner layer of wood pulp, or, an outer layer of wood pulp and the inner layer of a plastic or colloidal mass. A number of moulds may be filled and dried simultaneously. The article may be impregnated, dyed or may have its surface changed by mechanical pressing before leaving the mould. As shown, the mould a consists of three parts a\ a<2>, a<3> each consisting of a support with a fine mesh thereon, as shown in dotted lines, which parts can be opened after drying and closed before re-filling with pulp. The mould is carried on a wing c on a sleeve g revoluble on the shaft e. In Fig. 2, the mould is shown at the filling station, the mould being clamped between the hopper h and a vacuum connection i by a lever k operated by a pressure cylinder l. The mould is filled with pulp through the hopper h by a tilting measuring vessel n, and in certain cases it may be desirable to introduce water into the mould before, after, or at the time of supplying the pulp, either by a second tilting vessel, or from below through a water connection o. The cock m is then opened and the water sucked out of the mould. The mould is then similarly clamped between a heating-medium connection q and a draining connection r. A number of drying stations may be provided to which the mould is secured in succession, so that drying agents under pressure and /or vacuum may be used, e.g. steam before final drying with hot air. The movements of the moulds, or of the stations, when the moulds are stationary, may be effected by hand or automatically, and a motion other than a rotary motion may be employed.
