Abstract: 203,966. Pritchard, C. E., and Coudour, E. M. Dec. 2, 1922. Recording music; transcribing-scales.-Music played on a piano or organ, including all the shades of tempi thereof, is recorded with the aid of pedals by an electromagnetic device utilizing red potassium ferricyanide. Depression of the keys a, b, Fig. 1, allows contacts d to drop and make contact with a bus-bar e<1> fixed longitudinally over the keyboard brackets f and set-screws g. The bar e<1> may be in sections adjustably connected together to allow of use in instruments in which the width of the keys varies. The contacts d are connected by a cable to electromagnets u arranged in rows at an angle to the direction of travel of the record strip, thus enabling the width of the latter to be reduced. Energization of an electromagnet u attracts an armature j pressing a marking-point n against the paper and completing an electric circuit, including a plate k<1> and the armature j and point n, through the paper and the bottom of a detachable tank l. The record paper coated with red potassium ferricyanide is drawn from a delivery-roll R<1>, over a guide-roll R<2> through water in the tank l, and thence by rolls R<3>, R' underneath the bottom of the tank. The two pedals of the piano, or two specially provided pedals on the organ, are utilized to mark the rhythm and standard tempo by means of contacts carried thereby, the right-hand pedal completing the circuits through two of the electromagnets u, thus obtaining a double mark indicating the first beat in a bar, and the lefthand pedal completing the circuit through one only of these two electromagnets, producing a single mark indicating the subsequent beats of the bar. The transcribing-scale consists of a slide movable by hand in a guide through which the record is passed, the slide having one edge inclined at an angle corresponding to the inclined arrangement of the electromagnets, being marked with divisions bearing the names of the notes, and co-operating with a fixed scale of note-values. Specification 105,938 is referred to.

Abstract: 604,987. Power meters. ALLAN, H. R., CURLING, C. D., COOK, A. H., SPENDLEY, W., ANDREWS; P:, and: WEIGHT, C. S. Dec. 11, 1945, No. 33457. [Class 37] [Also in Group XL (c) To form a directive, coupling between a wave guide and a coaxial line, for example for power measuring purposes, the inner, conductor of the axial line is extended into the wave-guide as a looped coupling terminated so that it responds to or excites both transverse electric and magnetic fields in the waveguide, and means are provided for separately adjusting the relative magnitude and phase of the -electric and magnetic excitations. ' In Fig. 1 the inner conductor 2 of a coaxial line 2, 3 is extended into a wave-guide 1 to form a loop 6 which is terminated by a resistor 7 inside a coaxial sleeve 8. Loop 6 respondsto both transverse magnetic and transverse electric components in the waveguide, and the magnitudes of the effects may be made equal by rotating the loop assembly in the boss 4. Phase control is obtained, by axial movement of resistor 7. When this has been effected, the loop responds to, or excites, energy flowing in one direction only in the guide. This may be used for injecting energy for test purposes into a wave-guide connecting a receiver to an aerial. Or, if two such units are arranged to respond to energy in opposite directions, the forward and backward power may be measured, from which the standing wave ratio may be derived. Instead of resistance 7, an alternating cable may be used, or discs of lossy dielectric may be mounted on the conductor 9 close to the loop, and phase adjustment may be effected by axial movement of a piston behind the discs. Alternatively, conductor 9 may be made of insulating material which is coated near loop 6 with resistive material and elsewhere with conducting material. Phase adjustment may alternatively be effected by an adjustable screw projecting into the wave-guide to form a byepass capacity to the resistive impedance. Instead of using two directive couplings for the separate measurement of forward and backward power, a single unit retatable into two balanced conditions may be used. In Fig. 3 a unit 2, 3, 6, 7, 9 functioning as in Fig. 1 is mounted in a conical member 12 rotatable in a boss 13 on a waveguide 1. The two effective positions are marked by springs 16, 17 engaging notches in adjustable rings 14, carried on member 12.

Abstract: 936,276. Inductive control of apparatus. GENERAL MILLS Inc. Oct. 2, 1959 [Oct. 17, 1958], No. 33537/59. Class 40 (5). In a leader-gear system for remote control of a land vehicle, the electromagnetic vehicle path is defined by a pair of spaced parallel conductors, Fig. 2, which carry currents flowing in opposite directions, and auxiliary conductors disposed at various locations along the path are energized selectively to modify the electromagnetic field path at the corresponding locations to effect control over a vehicle thereat. The motor-driven vehicle, Fig. 1, has a vertical antenna 18 linked through a motor 20 to control the steering gear 16, and a horizontal antenna 24 for controlling the brakes and throttle of the driving motor. As shown, Fig. 2, the path defining conductors are formed from a single cable 49 energized from an A.C. generator 50, and the path includes a stopping zone 38, an intersection 34 and a turn-around 36. Selective energization of the various auxiliary conductors 52, 60, 62, 64, 66, &c. is effected by push-buttons 118, 120 . . . 130 which through relays connect the respective auxiliary conductors in series with the conductor 49. At the zone 38, for example, energization of auxiliary conductor 52 nullifies the field normally produced by both parallel sections of the cable 49 at the zone to stop the vehicle. At the intersection 34 an approaching vehicle will normally travel straight on, but if it is to turn it will be necessary to energize an appropriate pair of the auxiliary conductors 60. . . 66. For the turn-around 36 selective energization of the auxiliary conductors 88, 90 will cause an approaching vehicle to be diverted in the direction of arrow 200 or to move straight on (arrow 198) respectively.
