Title: Touch-responsive keying circuit for electronic musical instruments
IPC: H03B11/00
Filed: 1972-07-20
Abstract: 1385407 Electrophonic musical instruments NIPPON GAKKI SEIZO KK 20 July 1972 [20 July 1971(3)] 34080/72 Heading G5J A touch-responsive keying circuit 11 and gating circuit 12 give an output sound intensity which depends on the speed with which a key is depressed by the player. When the key is depressed, firstly, at time t 1 , contacts c, b of switch 21 break, and C 3  which has been charged nearly to 12V through R 7  starts to discharge through R 3  towards a potential Vc determined by R 3  and R 6 , as shown in Fig. 4. At a time t 2 , t 3  or t 4 , determined by the speed of depression of the key (touch), contacts c, m of switch 21 make, C 4  changes rapidly to a voltage W 1 , W 2  or W 3  which is essentially the voltage on C 3  at that instant, and the gate 12 opens in proportion to the voltage W. Because C 3  never discharges below Vc, some output is produced even if the key is depressed very slowly. The voltage W 1 , W 2  or W 3  is held by C 4 , as shown in Fig. 5, until the key is released, when contacts c, b of switch 27 close and C 4  discharges through R 4  and R 5 . An optional independent switch (25, Fig. 7, not shown), common to a set of keying circuits 11, selects an alternative mode of operation in which the gating voltage W is independent of touch.

IPC: B61L7/02
Filed: 1957-11-01
Abstract: 882,842. Thermal compensation for railway signal wires. RAILWAY SIGNAL CO. Ltd. Oct. 23, 1958 [Nov. 1, 1957], No. 34152/57. Class 105. In a signal wire compensator for use in mechanical signalling apparatus for railways, a bell-crank lever 17 and 18, to which a plate 15 anchoring the signal wires is coupled, is rotated about a pivot 14 in dependence upon the movements of thermal expansion and contraction in a control member 23. Each signal wire 28 (one only shown) is severed at the compensator, one end being attached to a swinging arm 21, supporting a stroke wheel 22, and the other end being attached to the anchor plate 15 and lapped back upon itself around the stroke wheel. Since the amount of thermal compensation required by any signal wire is a function of its length a plurality of holes 32 are provided in the anchor plate at varying distances from the pivot 14, thus the compensator can accommodate a group of signal wires of various lengths. A breakage in the control member 23 releases the weight 26 and hence the tension in the signal wires, thereby failing the system to safety.

Abstract: 462,626. Recovering gold &c. by amalgamation. FARR, C. C., and CADIGAN, J. M. Dec. 13, 1935, Nos. 34593 and 34594. Convention dates, Feb. 8 and May 15. [Class 82 (ii)] Gold and othe: metals are separa ted from sand &c by causing a wash containing the ma terial to impinge on a mercury surface connected to the negative pole of a direct current sup ply, the positive pole of which is connected to a line electrode arranged above the mercury but in contact with the wash. The action of the current which is most intense directly below the line electrode causes a reduction in the surface tension of the mercury along this line and consequent circulation of the mercury whereby the dross &c. on the mercury surface is withdrawn to the portions of the surface having a higher surface tension. A clean mercury surface is thus maintained below the line electrode. In the form shown the mercury is contained in a trough 1 and the line electrode 7 is attached to a transverse partition 5 which forces the wash into contact with the clean mercury surface below the electrode 7. The mercury surface and the particles of gold &c. are cleaned by the nascent hydrogen liberated at the surface of the mercury.
