Filed: 1968-08-09
Abstract: 1,187,182. Teaching aid for electronic musical instruments. WURLITZER CO. 9 Aug., 1968 [21 Aug., 1967], No. 38119/68. Heading G5X. An electronic teaching aid system includes a plurality of musical instruments each having means for selectively reproducing electric oscillations corresponding to audio tones, each musical instrument including an electro-acoustic transducer and carrying two connectors each of which co-operates with a similar connector on a length of jumper cable such that the jumper cables connect adjacent instruments together, the connectors having a sufficient number of terminals that the signals from all of the instruments pass through each connector, one only of the instruments being connected by a single cable to the teacher's piano A. Figure 1 shows a part simplified circuit diagram of the system in which a teacher's piano and two student pianos are shown. The pianos, of conventional design, comprise a tone generator-for example a vibrating reed- and associate amplifying apparatus, an oscillator 20, 20-1, 20-2 being provided for producing frequency vibrato. The teacher's piano is provided with an input for a microphone at 24, the microphone amplifier 26 being contained in a monitor unit 44. The student pianos are provided with a gramophone input at 22-1, 22-2 for orchestral accompaniment. The output of the teacher's piano may be switched to a loudspeaker 34 or headphone connection 38 from which a lead is taken to the monitor 44. The output of the student pianos may be switched between loudspeaker, headphones, or ensemble at 40-1, 40-2. This latter mode connects the output from the individual student pianos to a common wire 42 which leads to a switch 48 in the monitor and on through a group instruction switch 52 and emitter follower 58 and back to the individual pianos through individual emitter followers 62-1, 62-2. This enables the student to hear any other of the pianos that are switched to the ensemble mode. Switch 52 also provides for connection of audio aids, such as electric metronomes, to the student pianos. A " mike over " unit 96 is provided within the monitor to enable the teacher to talk to the students using his microphone. The closure of switch 152 causes signals from the microphone to pass down lead 116 and via switch 80 to lead 92 and ganged switch 68-1, 68-2 and hence to selected student pianos according to which switches 66-1, 66-2 are connected. The teacher's headphones are plugged into the monitor unit at 93. Figure 2 (not shown) illustrates, in plan view, a typical layout of pianos in which twelve pianos are utilized, in two rows of six, one connection being taken from the end piano in each row to the teacher's piano which faces the student pianos.

Title: Address adder for a program-controlled computer
IPC: G06F9/32
Filed: 1964-09-18
Abstract: 1,042,539. Computer programming arrangements. TELEFUNKEN PATENTVERWERTUNGSGESELLSCHAFT m.b.H. Sept. 18, 1964 [Oct. 8, 1963], No. 38191/64. Heading G4A. In a computer storage addressing arrangement in which the effective address for addressing a storage location is formed by combining a relative address for the location with a normally invariable reference address, the combination is effected by adding the higher orders of the relative address to the lower orders of the reference address so that if an increase in size of the store requires a longer effective address, this can be achieved by decreasing the number of digits of the relative and reference addresses which are added without increasing the number of digits in the relative and reference addresses themselves. As shown in Fig. 2, a 9-bit relative address on leads 14-22 is combined with a 6-bit reference address in register 7, the combination being effected by full adders 35-40, adders 35-37 receiving the three highest bits of the relative address and the three lowest bits of the reference address, the remaining adders 38-40 being provided to process carry signals. A 12-bit effective address is thus produced on output leads 23- 34. The length of the effective address may be increased by reconnecting the full adders so that fewer than the three adders 35-37 receive inputs from the relative and reference addresses. The computer described (Fig. 1, not shown), has a magnetic core store addressable for instructions by a counter.

The primary windings are connected through one or more generators to commutator C and the supply K and alternating current may be taken from the secondary or direct current may be obtained by rectifying and adding at the commutator C1 the phase displaced secondary voltages. For direct - current output, the auxiliary generators have secondary windings in series with the main secondaries. In the form shown in Fig. 6, the commutation improving generator G2 excited in proportion to the main secondary current has axial stator core members 20 .. 27 surrounded by primary and secondary armature coils 28 .. 35 and 28<1> . . 35<1> respectively, of which alternate primary coils are connected between coils 1 .. 4 of unit A and the rings 5, 6 of commutator C and the remainder to rings 7, 8 and coils 1 .. 4 on B. The secondaries 28<1> .. 35<1> are similarly divided into two sets and connected in a corresponding manner to the commutator C1 and secondaries 11 .. 4<1> of A and B, but in this case with the interposition of transformers T<1>, T<2> each connected as shown in Fig. 7, which relates to machine half A only. G1 is an auxiliary generator similar to G2 except that its excitation is proportional to the no load current of the transformer ; it is connected in series with G2 and the main windings and has windings 58 .. 65 (primary) and 58<1> .. 65<1> (secondary) half of each set being connected to each part of the main machine. In Fig. 7, the windings 28, 30, 32, 34 are represented by G2l and connected in series with windings 58, 60, 62, 64 represented by G1l and with the primary P of the part A. The corresponding secondary windings of G2, G1, represented by G2 l1 and G1l1 are connected through transformer T1 to the secondary S of machine half A. The generator G1 which compensates for no load losses of the main machine may have exciting windings acting in opposition connected in both primary and secondary circuits or may have only one exciting winding. The transformers T1, T2 are connected in the circuit of higher voltage which is not necessarily the secondary. The generator G1 may be omitted and the no load losses compensated by a motor. The commutation may be further improved by dividing the brushes into two or more parts with condensers connected therebetween. The commutation generator may alternatively be separately excited. Specifications 323,498, [Class 35, Dynamo-electric generators &c.], and 360,418 are referred to.
