Title: Improvements in or relating to electrical musical instruments
Inventor: LANGER NICOLAS
IPC: G10H5/10
Filed: 1930-04-24
Abstract: 353,918. Electrical musical instruments. LANGER, N. and HALMAGYI, J., 3, S÷rhßz- Utca, Budapest. April 24, 1930, No. 12686. [Classes 88 (i) and 88 (ii).] Relates to electrical instruments employing a glowdischarge lamp (or lamps) G in circuit with a battery B and resistance R, a condenser C being in shunt across either the lamp or the resistance. Fig. 6 shows an arrangement for producing from one lamp, two notes at a seldomused interval apart, e.g. a note and its sharp. The lamp G with condenser C in shunt, is in series with two resistances R\ R<2> respectively put into circuit, to sound the telephone or the like L, by the instrument keys K<1>, K<2>. In Fig. 4, the lamps of a series of notes are connected to an amplifier A and loud-speaker L through transformers T preventing interference between the circuits. A potentiometer M enables the frequency in each circuit to be regulated. A resistance Z regulates the intensity and the instrument is preferably arranged in sections so that the lesser audibility of lower notes may be compensated. A multi-lamp, as shown in Fig. 3, may be used instead of a number of separate lamps. A tremolo may be produced (Fig. 5, not shown) by superposing on the note circuit, by means of a common transformer, oscillations of from 10 to 15 per second produced by a similar lamp circuit. The keys K<1> .. may be replaced by contacts operated automatically by a tune-sheet (Fig. 7, not shown). The keys may consist of fixed insulated nickel and copper contact plates arranged like the keys of a piano, which are touched by the operator, the current passing through his body. Fig. 8 shows an arrangement imitating a stringed instrument. A string is represented by a thread of silk overwound with a thin filament of metal having a high specific resistance making a resistance of from 200,000 to 300,000 ohms. This resistance is fingered by the operator who with the other hand touches a key K<2>, the current passing through his body. By touching a different key K<3> connecting to a different voltage, the effect of playing on a different string is obtained. Or more than one resistance, each with its own lamp circuit may be employed. The currents obtained from the lamps may be used directly for making sound records or for wireless transmission. The influences of electrostatic fields and temperature on the lamps may be reduced by surrounding them with grounded metal shields ; the constancy of the oscillations may also be improved by saturating the electrodes with the gas before sealing the bulb. Variation of timbre may be obtained by coupling the circuits as in an organ, or by using loud-speakers of various timbres in combination.

Abstract: 725,378. Fluid-pressure servomotor-control systems. INTERNATIONAL HARVESTER CO. May 11, 1953 [May 13, 1952], No. 13076/53. Class 135. In hydraulic control apparatus such as is employed for the raising and lowering of agricultural implements, a control valve for a hydraulic motor 17 has lands 43, 44 controlling ports 39, 41 leading to opposite ends of the motor, and a third land 42 controlling a plunger which operates a by-pass valve 83 in a conduit 23, 25 connecting a hydraulic supply pump P with an inlet chamber 35 of the control valve whereby the by-pass valve is opened when the control valve is in neutral position closing the ports 39, 41. Chambers 45, 47, 48 are interconnected by drillings 49, 51, 52 and lead to exhaust through the right-hand, open, end of the bore housing the control valve. A passage 91, 95, incorporating a restriction 94 leads from the pump delivery to ports 36 controlled by the land 42, and the plunger for operating the by-pass valve is exposed to the pressure in the section 95. Movement of the control valve opens the passage 91, 95 to exhaust to allow a spring 84 to close the by-pass valve. The ports 39, 41 connect with the motor 17 through passages 54, 55, check valves 56, 57 and passages 72, 75, the check valves causing the motor to be hydraulically locked when the control valve is in neutral position. Pressure fluid in either passage 54, 55 opens the corresponding check valve to pass to one end of the motor and also moves a plunger 65 to open the other check valve so that the other end of the motor may exhaust. The ports 39, 41 are supplemented by smaller ports (not shown) which are offset in the axial direction of the control valve so as to be opened slightly in advance of the main ports 39, 41. The control valve is actuated through differential gearing 96 and is returned to neutral position by a feedback linkage 104 between the member operated by the motor 17 and the differential gearing.

Abstract: 1,000,852. Rotameter circuit. FORGES & ATLIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. April 3, 1963 [May 16, 1962], No. 13193/63. Heading H3A. An arrangement for indicating and/or controlling angular speeds with reference to a predetermined value comprises a tachometer alternator A coupled to the rotating member, two circuits one including a resistor Z1 and the other a capacitor Z2 which connect the alternator output to an amplitude comparator D which supplies an output to indicating means (not shown) or operates a relay 5 when the speed passes through a critical value. The comparator includes a pair of saturable magnetic circuits 1, 2 to which the input currents, after rectification, are coupled in opposition via coils 12, 23 which carry the resister circuit current and coils 13, 22 which carry the capacitor current. A.C. source S is also coupled to the magnetic circuits via coils 11, 21, rectifiers 9, 10, relay 5 and an indicating device if required. When the alternator frequency is below a critical value wp, Fig. 5, the current via the resistor Z1 is greater than that via the capacitor Z2 and the difference current which acts in the same direction as current from source S saturates the magnetic circuits hence the current in the indicating circuit has a high value P<SP>1</SP> which operates the relay. When the alternator frequency has a value above critical, the difference current is opposed by the current from source S, the circuits are not saturated and the indicating current has a low value P 2  which is not sufficient to operate the relay. Between these values the current curve has a steep slope providing if required a sensitive indication of speed. The relay may be used to control the speed of the rotating member.
