Title: Action for keyboard stringed musical instruments
IPC: G10C3/16
Filed: 1935-10-29
Abstract: 451,554. Pianoforte actions. PAPE, W., 87, Prinzregentenstrasse, Wilmersdorf, Berlin. Oct. 29, 1935, No. 29884. Convention date, Feb. 21. [Class 88 (ii)] The key 1 operates on the hammer-butt 7 or stem 5<1> either directly, Fig. 1, or through only a single lever 29, Fig. 5, and the striking-member rigidly carries an adjustable auxiliary check 13, which latter, in the check position shown, co-operates with an adjustable headed striking screw 10, to clamp the hammer firmly at two points on opposite sides of its pivot 27, with a force depending on the pressure applied to the key. The striking is performed in consequence of the elasticity in the hammer butt and stem, in the cushions 21, 13 and in the striking- member 3, Fig. 1, or 29, Fig. 5, which latter may be of metal and be resilient. In Fig. 1, the striking-member 3 is constituted by a downward or upward bend 3 of the key, and the hammer-butt 7 has a forked part 9, loosely surrounding and retaining the striking-screw 10. The struck surface 21 of the hammer-butt is rounded to produce rolling contact with the rounded head of the screw 10. In the grand piano shown in Fig. 5, the key 1 acts on the striking-lever 29 through a screw 23, and the striking-screw acts on the hammer-stem 51 through a deerskin roller 21<1>. The arrangement reduces the size of grand or upright pianos.

[Also in Divisions G4, and H1] In a field-effect transistor memory, each cell comprises a charge storage device charged through a field-effect transistor coupled to one of a plurality of word lines and one of a plurality of bit lines. In Fig. 1, a word line 24 is energized to cause respective MOS insulated-gate field-effect transistors 12 to conduct to charge associated capacitors 14 according to bit values on bit lines 26 for write-in or discharge the capacitors to the bit lines for read-out. Fig. 3 (see Division H1) relates to a one bit cell of an integrated circuit construction. Fig. 5 shows a modified cell in which the capacitor is replaced by the gate-to-substrate capacitance of a second field-effect transistor 50. A modification includes a third field-effect transistor (having drain and gate connected to point 30 and source connected to the bit line) to prevent excessive charge build-up on the capacitance. An alternative modification has a separate word and bit line for each of the two transistors for writing and reading respectively. A separate capacitor could be inserted at point 30 in Fig. 5. Non-destructive read-out is possible with these modified cells, unlike Fig. 1. The NPN devices could be replaced by PNP.

Abstract: 1359361 Polymerization using electric fields AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE 2 July 1971 [3 July 1970] 31147/71 Headings C3P and C3R A method of polymerization comprises subjecting a liquid comprising one or more monomers to be polymerized, previously freed from traces of impurities tending to inhibit the polymerization, to the polymerizing action of a non-uniform electrical field of maximum intensity greater than 10<SP>5</SP> volts/cm established between electrodes dipping into the liquid. At least one of the electrodes may have a surface or projecting portion which is directed towards the other electrode and has a principal radius of curvature sufficiently small, e.g. less than 10 micrometres, to enable the establishment of the electrical field by means of a potential difference between the electrodes of between 1 and 100 kilo volts. The electrode may have a point or sharp edge or be consituted by a conductor wire or a metallic surface having asperities obtained by treatment with an abrasive. The other electrode may have a flat, cylindrical or spherical surface or be in the shape of a ring or grid. The liquid may be neat monomer or a solution of monomer in a solvent. In the examples pure styrene and pure methyl methacrylate are polymerized using in Example 3 a tungsten point, a razor blade, a brass plate which had been treated with abrasive and a polished brass disc as electrodes. Vinyl chloride and methyl methacrylate may be polymerized alone or dissolved in benzene or tetrahydrofurane. Tetrahydrofurane may also be polymerized by using the electrode with a projecting portion connected to the positive terminal.

Class 82(2) [Also in Groups XI, XXVIII and XL(a)]  A source of metal vapour for use in vacuum metallization apparatus comprises means for feeding a metal wire downwardly on to or  adjacent a cooled surface and means providing electrons whch bombard the end of the wire to produce a molten droplet emitting metal -vapour, said droplet adhering to the portion of the cooled surface in proximity to the end of the wire and becoming suspended on said portion. As shown, metal wire 1 is fed through the hollow core of positive water-cooled block 4 from which it emerges to be heated by electron bombardment from circular filament 5, vapour being emitted from droplet 7. Negative ring shield 8 surrounds the filament and prevents electron bombardment of nearby positive fittings.
