[Also in Division H4] Apparatus for generating a complex multifrequency signal for use in diagnosing or treating disease comprises three or more electronic oscillators A1 to A8, each being variable independently of the others through a range extending from 5 cycles/sec. into the radio frequency band, a common mixer 12 to a preamplifier B1 and a main amplifier (D) to which the preamplifier output signal is supplied. Eight oscillators A1-A8, each independently capable of adjustment to produce frequencies between 1 cycle/sec. and 150 kilocycles/sec., are connected through a common bus-bar 12 and a preamplifier B1 to output terminals C1 and C2. One terminal Cl is connected through the main amplifier D to a loudspeaker, a vibrator, sound emitter or apparatus in which the frequency pattern produced by the oscillators is superimposed on a light carrier signal for treatment purposes. The other terminal C2 is connected to a tape recorder F on which the frequency pattern produced by the oscillators may be recorded. A tape recording of one frequency pattern produced by the oscillators or a sound or light signal received from the patient through a suitable transducer e.g. a microphone, may be fed into a second pre-amplifier B2 through an input terminal 20 and thus combined with a second frequency pattern produced by the oscillators at either output terminal Cl, C2. the resulting frequency pattern then being fed through the main amplifier D for application to the patient or to the tape recorder. Alternatively, sound waves (e.g. below 5 cycles/sec.) derived from the patient may be picked up by a microphone (see Division H4) and fed to the second preamplifier B2 through the terminal 20 and thus combined with the frequency pattern produced by the oscillators. The patient may be scanned by a sonic beam containing a recorded frequency pattern derived from the apparatus or infra-red light and the energy reflected from the patient picked up by a microphone or a light transducer and displayed on an oscillscope for diagnostic purposes or fed to the preamplifier B2.

Filed: 1946-08-30
Abstract: 616,220. Protractors. FUCHS, P. Aug. 30, 1946, No. 26103. [Class 97 (iii)] An adjustable protractor comprises a blade sliding in a slot in the protractor head which is urged to contact along one edge two circular sectioned surfaces, one of which is fixed and the other is interposed between the blade edge and a micrometer. As shown, the protractor head 20 is bored with two blind holes 22, 23 parallel to its length, both holes entering the slot 24 in which slides the blade 36. A hardened ball 28 is locked tight in the spherical end of the hole 23 by a screwed plug 29 and a second ball 35 is positioned in the hole 22 by the spindle 33 of the micrometer 31, 32, the body 31 of which may be secured by grub-screws or by sweating in position. The blade 36 is retained in the slot 24 with its edge 37 bearing against the balls 28, 35 by a plunger 38 having one end cut away to leave a hook 42 of generally elliptical cross-section to engage in the groove 43 of the blade 36. The plunger 38 is located within an intermediate hole 39 parallel to the holes 22, 23, but off-set slightly from their axial plane, the hole 39 being counterbored at 44 to receive a spring 45 bearing on the head 46 of the plunger, thereby urging the blade into contact with the balls. A tab 47 on the plunger head 46 passes through a slot 48 to engage a cam portion 50 on a locking member 51 located in the counterbored portion 49 of the hole 23. When the knob 53 is rotated until the open portion of the cam surface is in line with the tab 47, the plunger is free to move in its guide 39, 44 so that the angle between the protractor blade and the head may be adjusted by the micrometer. After adjustment, rotation of the knob 53 causes the cam face 55 to engage with the tab 47, thereby locking the plunger with the blade held securely against the balls in the required position. Rotation of the knob 53 in the opposite direction causes tab 47 to engage cam face 60,. thereby displacing the plunger against the action of the spring 45 so that the blade may be removed. In a modification the micrometer is enclosed in the protractor head, which is cut away to expose the micrometer scale and to provide access to the sleeve for adjustment purposes. Blades of L- and T-shaped section are also described and also the application of cranked blades whereby measurements may be made in various ranges of angles.
